FIELD OF THE INVENTION

The field of the invention pertains to compounds of Formulas 0, I and II, and subformulas thereof, that are inhibitors of a Janus kinase, such as JAK1, as well as compositions containing these compounds, and methods of use including, but not limited to, diagnosis or treatment of patients suffering from a condition responsive to the inhibition of a JAK kinase.

BACKGROUND OF INVENTION

Cytokine pathways mediate a broad range of biological functions, including many aspects of inflammation and immunity. Janus kinases (JAK), including JAK1, JAK2, JAK3 and TYK2, are cytoplasmic protein kinases that associate with type I and type II cytokine receptors and regulate cytokine signal transduction. Cytokine engagement with cognate receptors triggers activation of receptor associated JAKs and this leads to JAK-mediated tyrosine phosphorylation of signal transducer and activator of transcription (STAT) proteins and ultimately transcriptional activation of specific gene sets (Schindler et al., 2007, J. Biol. Chem. 282: 20059-63). JAK1, JAK2 and TYK2 exhibit broad patterns of gene expression, while JAK3 expression is limited to leukocytes. Cytokine receptors are typically functional as heterodimers, and as a result, more than one type of JAK kinase is usually associated with cytokine receptor complexes. The specific JAKs associated with different cytokine receptor complexes have been determined in many cases through genetic studies and corroborated by other experimental evidence. Exemplary therapeutic benefits of the inhibition of JAK enzymes are discussed, for example, in International Application No. WO 2013/014567.

JAK1 was initially identified in a screen for novel kinases (Wilks A. F., 1989, Proc. Natl. Acad. Sci. U.S.A. 86:1603-1607). Genetic and biochemical studies have shown that JAK1 is functionally and physically associated with the type I interferon (e.g., IFNalpha), type II interferon (e.g., IFNgamma), and IL-2 and IL-6 cytokine receptor complexes (Kisseleva et al., 2002, Gene 285:1-24; Levy et al., 2005, Nat. Rev. Mol. Cell Biol. 3:651-662; O'Shea et al., 2002, Cell, 109 (suppl.): S121-S131). JAK1 knockout mice die perinatally due to defects in LIF receptor signaling (Kisseleva et al., 2002, Gene 285:1-24; O'Shea et al., 2002, Cell, 109 (suppl.): S121-S131). Characterization of tissues derived from JAK1 knockout mice demonstrated critical roles for this kinase in the IFN, IL-10, IL-2/IL-4 and IL-6 pathways. A humanized monoclonal antibody targeting the IL-6 pathway (Tocilizumab) was recently approved by the European Commission for the treatment of moderate-to-severe rheumatoid arthritis (Scheinecker et al., 2009, Nat. Rev. Drug Discov. 8:273-274).

CD4 T cells play an important role in asthma pathogenesis through the production of TH2 cytokines within the lung, including IL-4, IL-9 and IL-13 (Cohn et al., 2004, Annu. Rev. Immunol. 22:789-815). IL-4 and IL-13 induce increased mucus production, recruitment of eosinophils to the lung, and increased production of IgE (Kasaian et al., 2008, Biochem. Pharmacol. 76(2): 147-155). IL-9 leads to mast cell activation, which exacerbates the asthma symptoms (Kearley et al., 2011, Am. J. Resp. Crit. Care Med., 183(7): 865-875). The IL-4Ra chain activates JAK1 and binds to either IL-4 or IL-13 when combined with the common gamma chain or the IL-13RÎ±1 chain respectively (Pernis et al., 2002, J. Clin. Invest. 109(10):1279-1283). The common gamma chain can also combine with IL-9RÎ± to bind to IL-9, and IL-9RÎ± activates JAK1 as well (Demoulin et al., 1996, Mol. Cell Biol. 16(9):4710-4716). While the common gamma chain activates JAK3, it has been shown that JAK1 is dominant over JAK3, and inhibition of JAK1 is sufficient to inactivate signaling through the common gamma chain despite JAK3 activity (Haan et al., 2011, Chem. Biol. 18(3):314-323). Inhibition of IL-4, IL-13 and IL-9 signaling by blocking the JAK/STAT signaling pathway can alleviate asthmatic symptoms in pre-clinical lung inflammation models (Mathew et al., 2001, J. Exp. Med. 193(9): 1087-1096; Kudlacz et. al., 2008, Eur. J. Pharmacol. 582(1-3): 154-161).

Biochemical and genetic studies have shown an association between JAK2 and single-chain (e.g., EPO), IL-3 and interferon gamma cytokine receptor families (Kisseleva et al., 2002, Gene 285:1-24; Levy et al., 2005, Nat. Rev. Mol. Cell Biol. 3:651-662; O'Shea et al., 2002, Cell, 109 (suppl.): S121-S131). Consistent with this, JAK2 knockout mice die of anemia (O'Shea et al., 2002, Cell, 109 (suppl.): S121-S131). Kinase activating mutations in JAK2 (e.g., JAK2 V617F) are associated with myeloproliferative disorders in humans.

JAK3 associates exclusively with the gamma common cytokine receptor chain, which is present in the IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21 cytokine receptor complexes. JAK3 is critical for lymphoid cell development and proliferation and mutations in JAK3 result in severe combined immunodeficiency (SCID) (O'Shea et al., 2002, Cell, 109 (suppl.): S121-S131). Based on its role in regulating lymphocytes, JAK3 and JAK3-mediated pathways have been targeted for immunosuppressive indications (e.g., transplantation rejection and rheumatoid arthritis) (Baslund et al., 2005, Arthritis & Rheumatism 52:2686-2692; Changelian et al., 2003, Science 302: 875-878).

TYK2 associates with the type I interferon (e.g., IFNalpha), IL-6, IL-10, IL-12 and IL-23 cytokine receptor complexes (Kisseleva et al., 2002, Gene 285:1-24; Watford, W. T. & O'Shea, J. J., 2006, Immunity 25:695-697). Consistent with this, primary cells derived from a TYK2 deficient human are defective in type I interferon, IL-6, IL-10, IL-12 and IL-23 signaling. A fully human monoclonal antibody targeting the shared p40 subunit of the IL-12 and IL-23 cytokines (Ustekinumab) was recently approved by the European Commission for the treatment of moderate-to-severe plaque psoriasis (Krueger et al., 2007, N. Engl. J. Med. 356:580-92; Reich et al., 2009, Nat. Rev. Drug Discov. 8:355-356). In addition, an antibody targeting the IL-12 and IL-23 pathways underwent clinical trials for treating Crohn's Disease (Mannon et al., 2004, N. Engl. J. Med. 351:2069-79).

There exists a need in the art for additional or alternative treatments of conditions mediated by JAK kinases, such as those described above.

â€œStereoisomersâ€ refer to compounds that have identical chemical constitution, but differ with regard to the arrangement of the atoms or groups in space. Stereoisomers include diastereomers, enantiomers, conformers and the like.

â€œChiralâ€ refers to molecules which have the property of non-superimposability of the mirror image partner, while the term â€œachiralâ€ refers to molecules which are superimposable on their mirror image partner.

â€œDiastereomerâ€ refers to a stereoisomer with two or more centers of chirality and whose molecules are not mirror images of one another. Diastereomers have different physical properties, e.g., melting points, boiling points, spectral properties or biological activities. Mixtures of diastereomers may separate under high resolution analytical procedures such as electrophoresis and chromatography such as HPLC.

â€œEnantiomersâ€ refer to two stereoisomers of a compound which are non-superimposable mirror images of one another.

Stereochemical definitions and conventions used herein generally follow S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., â€œStereochemistry of Organic Compoundsâ€ , John Wiley & Sons, Inc., New York, 1994. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L, or R and S, are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and 1 or (+) and (âˆ’) are employed to designate the sign of rotation of plane-polarized light by the compound, with (âˆ’) or 1 meaning that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of one another. A specific stereoisomer may also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture or a racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process. The terms â€œracemic mixtureâ€ and â€œracemateâ€ refer to an equimolar mixture of two enantiomeric species, devoid of optical activity.

The term â€œtautomerâ€ or â€œtautomeric formâ€ refers to structural isomers of different energies which are interconvertible via a low energy barrier. For example, proton tautomers (also known as prototropic tautomers) include interconversions via migration of a proton, such as keto-enol and imine-enamine isomerizations. Valence tautomers include interconversions by reorganization of some of the bonding electrons.

Certain compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. A â€œsolvateâ€ refers to an association or complex of one or more solvent molecules and a compound of the present invention. Examples of solvents that form solvates include water, isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, and ethanolamine. Certain compounds of the present invention can exist in multiple crystalline or amorphous forms. In general, all physical forms are intended to be within the scope of the present invention. The term â€œhydrateâ€ refers to the complex where the solvent molecule is water.

A â€œmetaboliteâ€ refers to a product produced through metabolism in the body of a specified compound or salt thereof. Such products can result, for example, from the oxidation, reduction, hydrolysis, amidation, deamidation, esterification, deesterification, enzymatic cleavage, and the like, of the administered compound.

Metabolite products typically are identified by preparing a radiolabelled (e.g., ¹⁴C or ³H) isotope of a compound of the invention, administering it in a detectable dose (e.g., greater than about 0.5 mg/kg) to an animal such as rat, mouse, guinea pig, monkey, or to a human, allowing sufficient time for metabolism to occur (typically about 30 seconds to 30 hours) and isolating its conversion products from the urine, blood or other biological samples. These products are easily isolated since they are labeled (others are isolated by the use of antibodies capable of binding epitopes surviving in the metabolite). The metabolite structures are determined in conventional fashion, e.g., by MS, LC/MS or NMR analysis. In general, analysis of metabolites is done in the same way as conventional drug metabolism studies well known to those skilled in the art. The metabolite products, so long as they are not otherwise found in vivo, are useful in diagnostic assays for therapeutic dosing of the compounds of the invention.

â€œTherapeutically effective amountâ€ means an amount of a compound of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, that (i) treats or prevents the particular disease, condition or disorder, or (ii) attenuates, ameliorates or eliminates one or more symptoms of the particular disease, condition, or disorder, and optionally (iii) prevents or delays the onset of one or more symptoms of the particular disease, condition or disorder described herein. In some embodiments, the therapeutically effective amount is an amount sufficient to decrease or alleviate the symptoms of an autoimmune or inflammatory disease (e.g., asthma). In some embodiments, a therapeutically effective amount is an amount of a chemical entity described herein sufficient to significantly decrease the activity or number of B-cells. In the case of cancer, the therapeutically effective amount of the drug may reduce the number of cancer cells; reduce the tumor size; inhibit (i.e., slow to some extent and preferably stop) cancer cell infiltration into peripheral organs; inhibit (i.e., slow to some extent and preferably stop) tumor metastasis; inhibit, to some extent, tumor growth; or relieve to some extent one or more of the symptoms associated with the cancer. To the extent the drug may prevent growth or kill existing cancer cells, it may be cytostatic or cytotoxic. For cancer therapy, efficacy can, for example, be measured by assessing the time to disease progression (TTP) or determining the response rate (RR).

â€œTreatmentâ€ (and variations such as â€œtreatâ€ or â€œtreatingâ€ ) refers to clinical intervention in an attempt to alter the natural course of the individual or cell being treated, and can be performed either for prophylaxis or during the course of clinical pathology. Desirable effects of treatment include preventing occurrence or recurrence of disease, alleviation of symptoms, diminishment of any direct or indirect pathological consequences of the disease, stabilized (i.e., not worsening) state of disease, decreasing the rate of disease progression, amelioration or palliation of the disease state, prolonging survival as compared to expected survival if not receiving treatment and remission or improved prognosis. In some embodiments, compounds of the invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, are used to delay development of a disease or disorder or to slow the progression of a disease or disorder. Those in need of treatment include those already with the condition or disorder as well as those prone to have the condition or disorder, (for example, through a genetic mutation) or those in which the condition or disorder is to be prevented.

â€œInflammatory disorderâ€ refers to any disease, disorder or syndrome in which an excessive or unregulated inflammatory response leads to excessive inflammatory symptoms, host tissue damage, or loss of tissue function. â€œInflammatory disorderâ€ also refers to a pathological state mediated by influx of leukocytes or neutrophil chemotaxis.

â€œInflammationâ€ refers to a localized, protective response elicited by injury or destruction of tissues, which serves to destroy, dilute, or wall off (sequester) both the injurious agent and the injured tissue. Inflammation is notably associated with influx of leukocytes or neutrophil chemotaxis. Inflammation can result from infection with pathogenic organisms and viruses and from noninfectious means such as trauma or reperfusion following myocardial infarction or stroke, immune responses to foreign antigens, and autoimmune responses. Accordingly, inflammatory disorders amenable to treatment with a compound of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, encompass disorders associated with reactions of the specific defense system as well as with reactions of the nonspecific defense system.

â€œSpecific defense systemâ€ refers to the component of the immune system that reacts to the presence of specific antigens. Examples of inflammation resulting from a response of the specific defense system include the classical response to foreign antigens, autoimmune diseases, and delayed type hypersensitivity responses mediated by T-cells. Chronic inflammatory diseases, the rejection of solid transplanted tissue and organs, e.g., kidney and bone marrow transplants, and graft versus host disease (GVHD), are further examples of inflammatory reactions of the specific defense system.

The term â€œnonspecific defense systemâ€ refers to inflammatory disorders that are mediated by leukocytes that are incapable of immunological memory (e.g., granulocytes, and macrophages). Examples of inflammation that result, at least in part, from a reaction of the nonspecific defense system include inflammation associated with conditions such as adult (acute) respiratory distress syndrome (ARDS) or multiple organ injury syndromes; reperfusion injury; acute glomerulonephritis; reactive arthritis; dermatoses with acute inflammatory components; acute purulent meningitis or other central nervous system inflammatory disorders such as stroke; thermal injury; inflammatory bowel disease; granulocyte transfusion associated syndromes; and cytokine-induced toxicity.

â€œAutoimmune diseaseâ€ refers to any group of disorders in which tissue injury is associated with humoral or cell-mediated responses to the body's own constituents. Non-limiting examples of autoimmune diseases include rheumatoid arthritis, lupus and multiple sclerosis. â€œAllergic diseaseâ€ as used herein refers to any symptoms, tissue damage, or loss of tissue function resulting from allergy. â€œArthritic diseaseâ€ as used herein refers to any disease that is characterized by inflammatory lesions of the joints attributable to a variety of etiologies. â€œDermatitisâ€ as used herein refers to any of a large family of diseases of the skin that are characterized by inflammation of the skin attributable to a variety of etiologies. â€œTransplant rejectionâ€ as used herein refers to any immune reaction directed against grafted tissue, such as organs or cells (e.g., bone marrow), characterized by a loss of function of the grafted and surrounding tissues, pain, swelling, leukocytosis, and thrombocytopenia. The therapeutic methods of the present invention include methods for the treatment of disorders associated with inflammatory cell activation.

â€œInflammatory cell activationâ€ refers to the induction by a stimulus (including, but not limited to, cytokines, antigens or auto-antibodies) of a proliferative cellular response, the production of soluble mediators (including but not limited to cytokines, oxygen radicals, enzymes, prostanoids, or vasoactive amines), or cell surface expression of new or increased numbers of mediators (including, but not limited to, major histocompatability antigens or cell adhesion molecules) in inflammatory cells (including but not limited to monocytes, macrophages, T lymphocytes, B lymphocytes, granulocytes (i.e., polymorphonuclear leukocytes such as neutrophils, basophils, and eosinophils), mast cells, dendritic cells, Langerhans cells, and endothelial cells). It will be appreciated by persons skilled in the art that the activation of one or a combination of these phenotypes in these cells can contribute to the initiation, perpetuation, or exacerbation of an inflammatory disorder.

In some embodiments, inflammatory disorders which can be treated according to the methods of this invention include, but are not limited to, asthma, rhinitis (e.g., allergic rhinitis), allergic airway syndrome, atopic dermatitis, bronchitis, rheumatoid arthritis, psoriasis, contact dermatitis, chronic obstructive pulmonary disease and delayed hypersensitivity reactions.

The terms â€œcancerâ€ and â€œcancerousâ€ , â€œneoplasmâ€ , and â€œtumorâ€ and related terms refer to or describe the physiological condition in mammals that is typically characterized by unregulated cell growth. A â€œtumorâ€ comprises one or more cancerous cells. Examples of cancer include carcinoma, blastoma, sarcoma, seminoma, glioblastoma, melanoma, leukemia, and myeloid or lymphoid malignancies. More particular examples of such cancers include squamous cell cancer (e.g., epithelial squamous cell cancer) and lung cancer including small-cell lung cancer, non-small cell lung cancer (â€œNSCLCâ€ ), adenocarcinoma of the lung and squamous carcinoma of the lung. Other cancers include skin, keratoacanthoma, follicular carcinoma, hairy cell leukemia, buccal cavity, pharynx (oral), lip, tongue, mouth, salivary gland, esophageal, larynx, hepatocellular, gastric, stomach, gastrointestinal, small intestine, large intestine, pancreatic, cervical, ovarian, liver, bladder, hepatoma, breast, colon, rectal, colorectal, genitourinary, biliary passage, thyroid, papillary, hepatic, endometrial, uterine, salivary gland, kidney or renal, prostate, testis, vulval, peritoneum, anal, penile, bone, multiple myeloma, B-cell lymphoma, central nervous system, brain, head and neck, Hodgkin's, and associated metastases. Examples of neoplastic disorders include myeloproliferative disorders, such as polycythemia vera, essential thrombocytosis, myelofibrosis, such as primary myelofibrosis, and chronic myelogenous leukemia (CML).

A â€œchemotherapeutic agentâ€ is an agent useful in the treatment of a given disorder, for example, cancer or inflammatory disorders. Examples of chemotherapeutic agents are well-known in the art and include examples such as those disclosed in U.S. Publ. Appl. No. 2010/0048557, incorporated herein by reference. Additionally, chemotherapeutic agents include pharmaceutically acceptable salts, acids or derivatives of any of chemotherapeutic agents, as well as combinations of two or more of them.

â€œPackage insertâ€ is used to refer to instructions customarily included in commercial packages of therapeutic products that contain information about the indications, usage, dosage, administration, contraindications or warnings concerning the use of such therapeutic products.

The terms â€œcompound(s) of this invention,â€ and â€œcompound(s) of the present inventionâ€ and the like, unless otherwise indicated, include compounds of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, and stereoisomers (including atropisomers), geometric isomers, tautomers, solvates, metabolites, isotopes, salts (e.g., pharmaceutically acceptable salts), and prodrugs thereof. In some embodiments, solvates, metabolites, isotopes or prodrugs are excluded, or any combination thereof.

Unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. Exemplary isotopes that can be incorporated into compounds of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-249, 2-1 to 2-481 or 3-1, include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, and iodine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ³²P, ³³P, ³⁵S, ¹⁸F, ³⁶Cl, ¹²³I, and ¹²⁵I, respectively. Isotopically-labeled compounds (e.g., those labeled with ³H and ¹⁴C) can be useful in compound or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ¹⁴C) isotopes can be useful for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements). In some embodiments, in compounds of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, one or more hydrogen atoms are replaced by ²H or ³H, or one or more carbon atoms are replaced by ¹³C- or ¹⁴C-enriched carbon. Positron emitting isotopes such as ¹⁵O, ¹³N, ¹¹C, and ¹⁸F are useful for positron emission tomography (PET) studies to examine substrate receptor occupancy. Isotopically labeled compounds can generally be prepared by following procedures analogous to those disclosed in the Schemes or in the Examples herein, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.

It is specifically contemplated that any limitation discussed with respect to one embodiment of the invention may apply to any other embodiment of the invention. Furthermore, any compound or composition of the invention may be used in any method of the invention, and any method of the invention may be used to produce or to utilize any compound or composition of the invention.

The use of the term â€œorâ€ is used to mean â€œand/orâ€ unless explicitly indicated to refer to alternatives only or the alternative are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and â€œand/or.â€

Throughout this application, the term â€œaboutâ€ is used to indicate that a value includes the standard deviation of error for the device or method being employed to determine the value.

As used herein, â€œaâ€ or â€œanâ€ means one or more, unless clearly indicated otherwise. As used herein, â€œanotherâ€ means at least a second or more.

Headings used herein are intended only for organizational purposes.

Compounds of the invention may contain one or more asymmetric carbon atoms. Accordingly, the compounds may exist as diastereomers, enantiomers or mixtures thereof. The syntheses of the compounds may employ racemates, diastereomers or enantiomers as starting materials or as intermediates. Mixtures of particular diastereomeric compounds may be separated, or enriched in one or more particular diastereomers, by chromatographic or crystallization methods. Similarly, enantiomeric mixtures may be separated, or enantiomerically enriched, using the same techniques or others known in the art. Each of the asymmetric carbon or nitrogen atoms may be in the R or S configuration and both of these configurations are within the scope of the invention.

In the structures shown herein, where the stereochemistry of any particular chiral atom is not specified, then all stereoisomers are contemplated and included as the compounds of the invention. Where stereochemistry is specified by a solid wedge or dashed line representing a particular configuration, then that stereoisomer is so specified and defined. Unless otherwise specified, if solid wedges or dashed lines are used, relative stereochemistry is intended.

Another aspect includes prodrugs of the compounds of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, including known amino-protecting and carboxy-protecting groups which are released, for example hydrolyzed, to yield the compound of the present invention under physiologic conditions.

The term â€œprodrugâ€ refers to a precursor or derivative form of a pharmaceutically active substance that is less efficacious to the patient compared to the parent drug and is capable of being enzymatically or hydrolytically activated or converted into the more active parent form. See, e.g., Wilman, â€œProdrugs in Cancer Chemotherapyâ€ Biochemical Society Transactions, 14, pp. 375-382, 615th Meeting Belfast (1986) and Stella et al., â€œProdrugs: A Chemical Approach to Targeted Drug Delivery,â€ Directed Drug Delivery, Borchardt et al., (ed.), pp. 247-267, Humana Press (1985). Prodrugs include, but are not limited to, phosphate-containing prodrugs, thiophosphate-containing prodrugs, sulfate-containing prodrugs, peptide-containing prodrugs, D-amino acid-modified prodrugs, glycosylated prodrugs, (3-lactam-containing prodrugs, optionally substituted phenoxyacetamide-containing prodrugs or optionally substituted phenylacetamide-containing prodrugs, and 5-fluorocytosine and 5-fluorouridine prodrugs.

A particular class of prodrugs are compounds in which a nitrogen atom in an amino, amidino, aminoalkyleneamino, iminoalkyleneamino or guanidino group is substituted with a hydroxy group, an alkylcarbonyl (â€”COâ€”R) group, an alkoxycarbonyl (â€”COâ€”OR), or an acyloxyalkyl-alkoxycarbonyl (â€”COâ€”Oâ€”Râ€”Oâ€”COâ€”R) group where R is a monovalent or divalent group, for example alkyl, alkylene or aryl, or a group having the Formula â€”C(O)â€”Oâ€”CP1P2-haloalkyl, where P1 and P2 are the same or different and are hydrogen, alkyl, alkoxy, cyano, halogen, alkyl or aryl. In a particular embodiment, the nitrogen atom is one of the nitrogen atoms of the amidino group of the compounds of Formula 0, Formula I or Formula II. Prodrugs may be prepared by reacting a compound of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, with an activated group, such as acyl groups, to bond, for example, a nitrogen atom in the compound to the exemplary carbonyl of the activated acyl group. Examples of activated carbonyl compounds are those containing a leaving group bonded to the carbonyl group, and include, for example, acyl halides, acyl amines, acyl pyridinium salts, acyl alkoxides, acyl phenoxides such as p-nitrophenoxy acyl, dinitrophenoxy acyl, fluorophenoxy acyl, and difluorophenoxy acyl. The reactions are generally carried out in inert solvents at reduced temperatures such as âˆ’78 to about 50Â° C. The reactions may also be carried out in the presence of an inorganic base, for example potassium carbonate or sodium bicarbonate, or an organic base such as an amine, including pyridine, trimethylamine, triethylamine, triethanolamine, or the like.

Additional types of prodrugs are also encompassed. For instance, a free carboxyl group of a compound of the invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or suitable free carboxyl-containing compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, can be derivatized as an amide or alkyl ester. As another example, compounds of the present invention comprising free hydroxy groups can be derivatized as prodrugs by converting the hydroxy group into a group such as, but not limited to, a phosphate ester, hemisuccinate, dimethylaminoacetate, or phosphoryloxymethyloxycarbonyl group, as outlined in Fleisher, D. et al., (1996) Improved oral drug delivery: solubility limitations overcome by the use of prodrugs Advanced Drug Delivery Reviews, 19:115. Carbamate prodrugs of hydroxy and amino groups are also included, as are carbonate prodrugs, sulfonate esters and sulfate esters of hydroxy groups. Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers, wherein the acyl group can be an alkyl ester optionally substituted with groups including, but not limited to, ether, amine and carboxylic acid functionalities, or where the acyl group is an amino acid ester as described above, are also encompassed. Prodrugs of this type are described in J. Med. Chem., (1996), 39:10. More specific examples include replacement of the hydrogen atom of the alcohol group with a group such as (C₁-C₆)alkanoyl oxymethyl, 1-((C₁-C₆)alkanoyloxy)ethyl, 1-methyl-1-((C₁-C₆)alkanoyloxy)ethyl, (C₁-C₆)alkoxycarbonyloxymethyl, Nâ€”(C₁-C₆)alkoxycarbonylaminomethyl, succinoyl, (C₁-C₆)alkanoyl, alpha-amino(C₁-C₄)alkanoyl, arylacyl and alpha-aminoacyl, or alpha-aminoacyl-alpha-aminoacyl, where each alpha-aminoacyl group is independently selected from the naturally occurring L-amino acids, P(O)(OH)₂, â€”P(O)(O(C₁-C₆)alkyl)₂or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal form of a carbohydrate).

â€œLeaving groupâ€ refers to a portion of a first reactant in a chemical reaction that is displaced from the first reactant in the chemical reaction. Examples of leaving groups include, but are not limited to, halogen atoms, alkoxy and sulfonyloxy groups. Example sulfonyloxy groups include, but are not limited to, alkylsulfonyloxy groups (for example methyl sulfonyloxy (mesylate group) and trifluoromethylsulfonyloxy (triflate group)) and arylsulfonyloxy groups (for example p-toluenesulfonyloxy (tosylate group) and p-nitrosulfonyloxy (nosylate group)).

Synthesis of Janus Kinase Inhibitor Compounds

Compounds of the present invention may be synthesized by synthetic routes described herein. In certain embodiments, processes well-known in the chemical arts can be used, in addition to, or in light of, the description contained herein. The starting materials are generally available from commercial sources such as Aldrich Chemicals (Milwaukee, Wis.) or are readily prepared using methods well known to those skilled in the art (e.g., prepared by methods generally described in Louis F. Fieser and Mary Fieser, Reagents for Organic Synthesis, v. 1-19, Wiley, N.Y. (1967-1999 ed.), Beilsteins Handbuch der organischen Chemie, 4, Aufl. ed. Springer-Verlag, Berlin, including supplements (also available via the Beilstein online database)), or Comprehensive Heterocyclic Chemistry, Editors Katrizky and Rees, Pergamon Press, 1984.

Compounds may be prepared singly or as compound libraries comprising at least 2, for example 5 to 1,000 compounds, or 10 to 100 compounds. Libraries of compounds may be prepared by a combinatorial â€˜split and mixâ€™ approach or by multiple parallel syntheses using either solution phase or solid phase chemistry, by procedures known to those skilled in the art. Thus according to a further aspect of the invention there is provided a compound library comprising at least 2 compounds of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1.

For illustrative purposes, reaction Schemes 1-24 depicted below provide routes for synthesizing the compounds of the present invention as well as key intermediates. For a more detailed description of the individual reaction steps, see the Examples section below. Those skilled in the art will appreciate that other synthetic routes may be used. Although some specific starting materials and reagents are depicted in the Schemes and discussed below, other starting materials and reagents can be substituted to provide a variety of derivatives or reaction conditions. In addition, many of the compounds prepared by the methods described below can be further modified in light of this disclosure using conventional chemistry well known to those skilled in the art.

In the preparation of compounds of the present invention, protection of remote functionality (e.g., primary or secondary amine) of intermediates may be necessary. The need for such protection will vary depending on the nature of the remote functionality and the conditions of the preparation methods. Suitable amino-protecting groups include acetyl, trifluoroacetyl, benzyl, phenylsulfonyl, t-butoxycarbonyl (BOC), benzyloxycarbonyl (CBz) and 9-fluorenylmethyleneoxycarbonyl (Fmoc). The need for such protection is readily determined by one skilled in the art. For a general description of protecting groups and their use, see T. W. Greene, Protective Groups in Organic Synthesis, John Wiley & Sons, New York, 1991.

Other conversions commonly used in the synthesis of compounds of the present invention, and which can be carried out using a variety of reagents and conditions, include the following:

(1) Reaction of a carboxylic acid with an amine to form an amide. Such a transformation can be achieved using various reagents known to those skilled in the art but a comprehensive review can be found in Tetrahedron, 2005, 61, 10827-10852.
(2) Reaction of a primary or secondary amine with an aryl halide or pseudo halide, e.g., a triflate, commonly known as a â€œBuchwald-Hartwig cross-coupling,â€ can be achieved using a variety of catalysts, ligands and bases. A review of these methods is provided in Comprehensive Organic Name Reactions and Reagents, 2010, 575-581.
(3) A palladium cross-coupling reaction between an aryl halide and a vinyl boronic acid or boronate ester. This transformation is a type of â€œSuzuki-Miyaura cross-coupling,â€ a class of reaction that has been thoroughly reviewed in Chemical Reviews, 1995, 95(7), 2457-2483.
(4) The hydrolysis of an ester to give the corresponding carboxylic acid is well known to those skilled in the art and conditions include: for methyl and ethyl esters, the use of a strong aqueous base such as lithium, sodium or potassium hydroxide or a strong aqueous mineral acid such as HCl; for a tert-butyl ester, hydrolysis would be carried out using acid, for example, HCl in dioxane or trifluoroacetic acid (TFA) in dichloromethane (DCM).

Scheme 1 provides details of the reactions available for the preparation of compounds of the invention wherein R²of Formula 0 is of type (a). Compound (1-3) can be prepared from 3-bromo-2-aminopyridine (1-1) according to WO2009/155551, incorporated herein by reference, and may undergo a Buchwald-Hartwig cross-coupling reaction with an aryl halide, an example of which would be ethyl 4-iodobenzoate, using a catalyst such as tris(dibenzylideneacetone)dipalladium (0) (Pd₂(dba)₃) or palladium (II) acetate (Pd(OAc)₂), a phosphine ligand such as 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) and a base such as caesium carbonate. Where (1-1) has additional substituents in the pyridine ring, a compound (1-3) having additional substitution in the 6-membered ring can be prepared. A wide range of substituted 3-bromo-2-aminopyridines are known in the literature and are commercially available and the preparations of compounds (i), (ii) and (iii) from the corresponding substituted 3-bromo-2-aminopyridine, using analogous chemistry to that shown for (1-3) in Scheme 1, are described in WO2011/092272, WO2010/141796 and WO2010/141796, respectively, each incorporated herein by reference.

An ester (1-4) can be hydrolysed to the corresponding carboxylic acid (1-5) using standard conditions which would be dependent upon the particular ester group present. An amide (1-6) may be formed from (1-5) using an amine R¹R²NH under standard coupling conditions, for example using (O-(7-azabenzotriazol-1-yl)-N,N,Nâ€²,Nâ€²-tetramethyluronium hexafluorophosphate) (HATU) in the presence of a base such as N,N-diisopropylethylamine (DIPEA). Intermediate (1-6) may also be prepared directly from (1-3) and amide (1-7) using the same chemistries in an alternative sequence. Compound (1-6) may then be converted into (1-9) by reaction with a cyclic secondary amine (1-8) via a Buchwald-Hartwig cross-coupling using a palladium catalyst such as Pd₂(dba)₃and a suitable ligand such as Xantphos in the presence of a base providing structures of Formula 0 with R²being of type (a). Alternatively, ester (1-4) may undergo a palladium catalysed amination with (1-8) to give (1-10). The ester moiety in (1-10) may then be hydrolysed under standard conditions to give an acid (1-11) which then may be reacted with an amine R¹R²NH to give a compound (1-9).

[Image Omitted]

In Scheme 1, R³or R⁴may be further elaborated. For example, in Scheme 2, where R⁴is CH₂CN (2-1), the nitrile group may be converted into the corresponding primary amide (2-2). Reagents suitable for this conversion include acetaldoxime in the presence of palladium (II) acetate and triphenylphosphine. The nitrile group in (2-1) may also be hydrolysed to the corresponding carboxylic acid (2-3) which in turn can be treated with an amine R⁴R⁵NH under standard amidation conditions to provide compounds of type (2-4).

[Image Omitted]

Where R⁴in the compounds of Scheme 1 is an ester, exemplified by structure (3-1) of Scheme 3, this group may be hydrolysed under standard conditions to give an acid of type (3-2). Common amidation conditions may then be used to prepare an amide (3-3) from (3-2) and a suitable amine R³R⁴NH.

[Image Omitted]

The cyclic secondary amine (1-8) of Scheme 1, in which R⁴is hydroxyl and R³is an optionally substituted alkyl, aryl or heteroaryl group, may be prepared according to Scheme 4. Reaction of a suitably nitrogen protected aminoketone (4-1) with either a Grignard reagent or an organolithium may provide the alcohol (4-2). Deprotection of the amine nitrogen to give amine (4-3) can then be achieved using conditions designed to remove the protecting group of choice.

[Image Omitted]

Schemes 5 to 8 and 18 to 24 describe the methods that can be used to prepare other cyclic secondary amines (1-8), of Scheme 1, which are required for preparation of examples where the required amine (1-8) is hitherto unknown in the scientific literature. The methods use standard reactions known to those skilled in the art.

Scheme 5 provides a preparation of 1-oxa-3,7-diazaspiro[4.4]nonan-2-one (5-4). Starting with the commercially available aminoalcohol (5-1), reaction with triphosgene, or one of its equivalents, followed by removal of the benzyl group by catalytic hydrogenation can provide (5-3).

[Image Omitted]

Scheme 6 describes routes to secondary amines (1-8) of Scheme 1 in which R³is phenyl or substituted phenyl and R⁴is either cyano (6-6) or hydroxymethyl (6-5). Treatment of a cyanomethylbenzene with a base such as sodium hydride and subsequent reaction of the resultant anion with commercially available (6-1) may provide (6-2). The deprotection of (6-2) under acidic conditions gives amine (6-6). Reduction of the nitrile in intermediate (6-2), using diisobutylaluminium hydride for example, affords the aldehyde (6-3) which may be further reduced to the alcohol (6-4) by treatment with sodium borohydride. Boc deprotection will give the amine (6-5).

[Image Omitted]

Scheme 7 shows methods that can be used to prepare a secondary amine (1-8) of Scheme 1 in which R³is hydrogen and R⁴is 2-(2-methoxyethoxy)pyridin-4-ylmethoxy (7-4). Treatment of Boc-protected 4-piperidinol (7-2) with a base such as potassium tert-butoxide, and reaction with commercially available 4-(chloromethyl)-2-(2-methoxyethoxy)pyridine (7-1) in the presence of an iodide source such as terabutylammonium iodide gives (7-3). Treatment of the latter with acid leads to Boc deprotection and provides amine (7-4)

[Image Omitted]

Scheme 8 describes routes to amines 1-8 from Scheme 1 in which R³is a phenyl or substituted phenyl and R⁴is either cyanomethyl (8-6), hydroxyethyl (8-9) or cyanoethyl (8-12). The synthesis of intermediates of type (8-5) is described in Journal of Medicinal Chemistry, 2011, 54 (11), 3756-3767 and Boc deprotection can be achieved by treatment with acid. Reduction of the nitrile in (8-5) firstly to the aldehyde (8-7) using diisobutylaluminium hydride and then to the alcohol (8-8) with sodium borohydride provides (8-8) which can be Boc-deprotected in acid to give (8-9). Conversion of the alcohol (8-8) into the corresponding methanesulfonate ester (8-10) and subsequent reaction with a cyanide source such as sodium cyanide provides (8-11). Boc-deprotection of (8-11) results in the formation of amine (8-12).

Analogous chemistries to those described in Scheme 1 may be used prepare compounds of the invention wherein R²of Formula 0 is of type (b) by replacing the cyclic secondary amine (1-8) with an amine of type (iv). Here, R³/R⁴may be modified further using standard chemistries.

[Image Omitted]

Scheme 9 indicates how other compounds of the invention may be prepared wherein R²of Formula 0 is of type (d). Ester (1-4) or amide (1-6) from Scheme 1 may undergo a palladium catalysed Buchwald-Hartwig cross-coupling with a diamine (9-1). Where R³in (9-5), or indeed (9-3), is a protecting group, it may be removed under standard conditions and the resulting amine (9-6) may be further modified through alkylation, arylation, acylation, sulfonylation etc.

[Image Omitted]

Scheme 10 indicates how other compounds of the invention may be prepared wherein R²of Formula 0 is of type (c). Either ester (1-4) or amide (1-6) from Scheme 1 may be reacted with a suitable boronate ester or boronic acid in a Suzuki-Miyaura cross-coupling reaction. An example of a palladium catalyst that may be useful in such a transformation would be bis(triphenylphosphine)palladium (II) dichloride (Pd(PPh₃)₂Cl₂). Where R³in intermediate (10-2) or (10-5) is a protecting group, it may be removed under standard conditions to give amines (10-3) and (10-6), respectively.

Methods of Separation

In each of the exemplary Schemes it may be advantageous to separate reaction products from one another or from starting materials. The desired products of each step or series of steps is separated or purified (hereinafter separated) to the desired degree of homogeneity by the techniques common in the art. Typically such separations involve multiphase extraction, crystallization or trituration from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods including, for example: reverse-phase and normal phase; size exclusion; ion exchange; supercritical fluid; high, medium, and low pressure liquid chromatography methods and apparatus; small scale analytical; simulated moving bed (SMB) and preparative thin or thick layer chromatography, as well as techniques of small scale thin layer and flash chromatography.

Another class of separation methods involves treatment of a mixture with a reagent selected to bind to or render otherwise separable a desired product, unreacted starting material, reaction by product, or the like. Such reagents include adsorbents or absorbents such as activated carbon, molecular sieves, ion exchange media, or the like. Alternatively, the reagents can be acids in the case of a basic material, bases in the case of an acidic material, binding reagents such as antibodies, binding proteins, selective chelators such as crown ethers, liquid/liquid ion extraction reagents (LIX), or the like.

Selection of appropriate methods of separation depends on the nature of the materials involved. Example separation methods include boiling point, and molecular weight in distillation and sublimation, presence or absence of polar functional groups in chromatography, stability of materials in acidic and basic media in multiphase extraction, and the like. One skilled in the art will apply techniques most likely to achieve the desired separation.

Diastereomeric mixtures can be separated into their individual diastereoisomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as by chromatography or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereoisomers and converting (e.g., hydrolyzing) the individual diastereoisomers to the corresponding pure enantiomers. Also, some of the compounds of the present invention may be atropisomers (e.g., substituted biaryls) and are considered as part of this invention. Enantiomers can also be separated by use of a chiral HPLC column or supercritical fluid chromatography.

A single stereoisomer, e.g., an enantiomer, substantially free of its stereoisomer may be obtained by resolution of the racemic mixture using a method such as formation of diastereomers using optically active resolving agents (Eliel, E. and Wilen, S., Stereochemistry of Organic Compounds, John Wiley & Sons, Inc., New York, 1994; Lochmuller, C. H., J. Chromatogr., 113(3):283-302 (1975)). Racemic mixtures of chiral compounds of the invention can be separated and isolated by any suitable method, including: (1) formation of ionic, diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure stereoisomers, and (3) separation of the substantially pure or enriched stereoisomers directly under chiral conditions. See: Drug Stereochemistry, Analytical Methods and Pharmacology, Irving W. Wainer, Ed., Marcel Dekker, Inc., New York (1993).

Diastereomeric salts can be formed by reaction of enantiomerically pure chiral bases such as brucine, quinine, ephedrine, strychnine, Î±-methyl-Î²-phenylethylamine (amphetamine), and the like with asymmetric compounds bearing acidic functionality, such as carboxylic acid and sulfonic acid. The diastereomeric salts may be induced to separate by fractional crystallization or ionic chromatography. For separation of the optical isomers of amino compounds, addition of chiral carboxylic or sulfonic acids, such as camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid can result in formation of the diastereomeric salts.

Alternatively, the substrate to be resolved is reacted with one enantiomer of a chiral compound to form a diastereomeric pair (Eliel, E. and Wilen, S., Stereochemistry of Organic Compounds, John Wiley & Sons, Inc., New York, 1994, p. 322). Diastereomeric compounds can be formed by reacting asymmetric compounds with enantiomerically pure chiral derivatizing reagents, such as menthyl derivatives, followed by separation of the diastereomers and hydrolysis to yield the pure or enriched enantiomer. A method of determining optical purity involves making chiral esters, such as a menthyl ester, e.g., (âˆ’) menthyl chloroformate in the presence of base, or Mosher ester, Î±-methoxy-Î±-(trifluoromethyl)phenyl acetate (Jacob, J. Org. Chem. 47:4165 (1982)), of the racemic mixture, and analyzing the NMR spectrum for the presence of the two atropisomeric enantiomers or diastereomers. Stable diastereomers of atropisomeric compounds can be separated and isolated by normal- and reverse-phase chromatography following methods for separation of atropisomeric naphthyl-isoquinolines (WO 96/15111, incorporated herein by reference). By method (3), a racemic mixture of two enantiomers can be separated by chromatography using a chiral stationary phase (Chiral Liquid Chromatography W. J. Lough, Ed., Chapman and Hall, New York, (1989); Okamoto, J. of Chromatogr. 513:375-378 (1990)). Enriched or purified enantiomers can be distinguished by methods used to distinguish other chiral molecules with asymmetric carbon atoms, such as optical rotation and circular dichroism. The absolute stereochemistry of chiral centers and enatiomers can be determined by x-ray crystallography.

Positional isomers, for example E and Z forms, of compounds of Formula 0, Formula I or Formula II, and intermediates for their synthesis, may be observed by characterization methods such as NMR and analytical HPLC. For certain compounds where the energy barrier for interconversion is sufficiently high, the E and Z isomers may be separated, for example by preparatory HPLC.

The pH of the formulation depends mainly on the particular use and the concentration of compound, but typically ranges anywhere from about 3 to about 8. In one example, a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, is formulated in an acetate buffer, at pH 5.

Factors for consideration in this context include the particular disorder being treated, the particular mammal being treated, the clinical condition of the individual patient, the cause of the disorder, the site of delivery of the agent, the method of administration, the scheduling of administration, and other factors known to medical practitioners.

It will be understood that the specific dose level for any particular patient will depend upon a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing treatment. Optimum dose levels and frequency of dosing will be determined by clinical trial, as is required in the pharmaceutical art. In general, the daily dose range for oral administration will lie within the range of from about 0.001 mg to about 100 mg per kg body weight of a human, often 0.01 mg to about 50 mg per kg, for example 0.1 to 10 mg per kg, in single or divided doses. In general, the daily dose range for inhaled administration will lie within the range of from about 0.1 Î¼g to about 1 mg per kg body weight of a human, preferably 0.1 Î¼g to 50 Î¼g per kg, in single or divided doses. On the other hand, it may be necessary to use dosages outside these limits in some cases.

The compounds of the invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, may be administered by any suitable means, including oral, topical (including buccal and sublingual), rectal, vaginal, transdermal, parenteral, subcutaneous, intraperitoneal, intrapulmonary, intradermal, intrathecal, inhaled and epidural and intranasal, and, if desired for local treatment, intralesional administration. Parenteral infusions include intramuscular, intravenous, intraarterial, intraperitoneal, or subcutaneous administration. In some embodiments, inhaled administration is employed.

The compounds of the present invention, such as a compound of Formula 0, I, Ia, Ib, Ic, Id, Ie, If, Ig or II, or a compound of any of Examples 1-1 to 1-303, 2-1 to 2-486 or 3-1, may be administered in any convenient administrative form, e.g., tablets, powders, capsules, lozenges, granules, solutions, dispersions, suspensions, syrups, sprays, vapors, suppositories, gels, emulsions, patches, etc. Such compositions may contain components conventional in pharmaceutical preparations, e.g., diluents (e.g., glucose, lactose or mannitol), carriers, pH modifiers, buffers, sweeteners, bulking agents, stabilizing agents, surfactants, wetting agents, lubricating agents, emulsifiers, suspending agents, preservatives, antioxidants, opaquing agents, glidants, processing aids, colorants, perfuming agents, flavoring agents, other known additives as well as further active agents.

Suitable carriers and excipients are well known to those skilled in the art and are described in detail in, e.g., Ansel, Howard C., et al., Ansel's Pharmaceutical Dosage

Forms and Drug Delivery Systems. Philadelphia: Lippincott, Williams & Wilkins, 2004; Gennaro, Alfonso R., et al. Remington: The Science and Practice of Pharmacy. Philadelphia: Lippincott, Williams & Wilkins, 2000; and Rowe, Raymond C. Handbook of Pharmaceutical Excipients. Chicago, Pharmaceutical Press, 2005. For example, carriers include solvents, dispersion media, coatings, surfactants, antioxidants, preservatives (e.g., antibacterial agents, antifungal agents), isotonic agents, absorption delaying agents, salts, preservatives, drugs, drug stabilizers, gels, binders, excipients, disintegration agents, lubricants, sweetening agents, flavoring agents, dyes, such like materials and combinations thereof, as would be known to one of ordinary skill in the art (see, for example, Remington's Pharmaceutical Sciences, pp 1289-1329, 1990). Except insofar as any conventional carrier is incompatible with the active ingredient, its use in the therapeutic or pharmaceutical compositions is contemplated. Exemplary excipients include dicalcium phosphate, mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate or combinations thereof. A pharmaceutical composition may comprise different types of carriers or excipients depending on whether it is to be administered in solid, liquid or aerosol form, and whether it need to be sterile for such routes of administration.

For example, tablets and capsules for oral administration may be in unit dose presentation form, and may contain conventional excipients such as binding agents, for example syrup, acacia, gelatin, sorbitol, tragacanth, or polyvinyl-pyrrolidone; fillers, for example, lactose, sugar, maize-starch, calcium phosphate, sorbitol or glycine; tabletting lubricant, for example, magnesium stearate, talc, polyethylene glycol or silica; disintegrants, for example, potato starch, or acceptable wetting agents such as sodium lauryl sulfate. The tablets may be coated according to methods well known in normal pharmaceutical practice. Oral liquid preparations may be in the form of, for example, aqueous or oily suspensions, solutions, emulsions, syrups or elixirs, or may be presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid preparations may contain conventional additives such as suspending agents, for example, sorbitol, syrup, methyl cellulose, glucose syrup, gelatin hydrogenated edible fats; emulsifying agents, for example, lecithin, sorbitan monooleate, or acacia; non-aqueous vehicles (which may include edible oils), for example, almond oil, fractionated coconut oil, oily esters such as glycerine, propylene glycol, or ethyl alcohol; preservatives, for example, methyl or propyl p-hydroxybenzoate or sorbic acid, and if desired conventional flavoring or coloring agents.

For topical application to the skin, a compound may be made up into a cream, lotion or ointment. Cream or ointment formulations which may be used for the drug are conventional formulations well known in the art, for example as described in standard textbooks of pharmaceutics such as the British Pharmacopoeia.

For delivery by inhalation, the compound is typically in the form of microparticles, which can be prepared by a variety of techniques, including spray-drying, freeze-drying and micronisation. Aerosol generation can be carried out using, for example, pressure-driven jet atomizers or ultrasonic atomizers, such as by using propellant-driven metered aerosols or propellant-free administration of micronized compounds from, for example, inhalation capsules or other â€œdry powderâ€ delivery systems.

By way of example, a composition of the invention may be prepared as a suspension for delivery from a nebulizer or as an aerosol in a liquid propellant, for example, for use in a pressurized metered dose inhaler (PMDI).

In some embodiments, a composition of the invention is in dry powder form, for delivery using a dry powder inhaler (DPI). Many types of DPI are known.

Microparticles for delivery by administration may be formulated with excipients that aid delivery and release. For example, in a dry powder formulation, microparticles may be formulated with large carrier particles that aid flow from the DPI into the lung. Suitable carrier particles are known, and include lactose particles; they may have a mass median aerodynamic diameter of, for example, greater than 90 Î¼m.

Enzymatic Assays

JAK Enzyme Assays were Carried Out as Follows:

The activity of the isolated recombinant JAK1 and JAK2 kinase domain was measured by monitoring phosphorylation of a peptide derived from JAK3 (Val-Ala-Leu-Val-Asp-Gly-Tyr-Phe-Arg-Leu-Thr-Thr, fluorescently labeled on the N-terminus with 5-carboxyfluorescein) using the Caliper LabChipÂ® technology (Caliper Life Sciences, Hopkinton, Mass.). To determine inhibition constants (K_i), compounds were diluted serially in DMSO and added to 50 Î¼L kinase reactions containing purified enzyme (1.5 nM JAK1, or 0.2 nM JAK2), 100 mM HEPES buffer (pH 7.2), 0.015% Brij-35, 1.5 Î¼M peptide substrate, ATP (25 Î¼M), 10 mM MgCl₂, 4 mM DTT at a final DMSO concentration of 2%. Reactions were incubated at 22Â° C. in 384-well polypropylene microtiter plates for 30 minutes and then stopped by addition of 25 Î¼L of an EDTA containing solution (100 mM HEPES buffer (pH 7.2), 0.015% Brij-35, 150 mM EDTA), resulting in a final EDTA concentration of 50 mM. After termination of the kinase reaction, the proportion of phosphorylated product was determined as a fraction of total peptide substrate using the Caliper LabChipÂ® 3000 according to the manufacturer's specifications. K_ivalues were then determined using the Morrison tight binding model (Morrison, J. F., Biochim. Biophys. Acta. 185:269-296 (1969); William, J. W. and Morrison, J. F., Meth. Enzymol., 63:437-467 (1979)) modified for ATP-competitive inhibition [K_i=K_i,app/(1+[ATP]/K_m,app)].

JAK1 Pathway Assay in Cell Lines was Carried Out as Follows:

Inhibitor potency (EC₅₀) was determined in cell-based assays designed to measure JAK1 dependent STAT phosphorylation. As noted above, inhibition of IL-4, IL-13, and IL-9 signaling by blocking the Jak/Stat signaling pathway can alleviate asthmatic symptoms in pre-clinical lung inflammation models (Mathew et al., 2001, J Exp Med 193(9): 1087-1096; Kudlacz et. al., 2008, Eur J. Pharmacol 582(1-3): 154-161).

In one assay approach, TF-1 human erythroleukemia cells obtained from the American Type Culture Collection (ATCC; Manassas, Va.) were used to measure JAK1-dependent STATE phosphorylation downstream of IL-13 stimulation. Prior to use in the assays, TF-1 cells were starved of GM-CSF overnight in OptiMEM medium (Life Technologies, Grand Island, N.Y.) supplemented with 0.5% charcoal/dextran stripped fetal bovine serum (FBS), 0.1 mM non-essential amino acids (NEAA), and 1 mM sodium pyruvate. The assays were run in 384-well plates in serum-free OptiMEM medium using 300,000 cells per well. In a second assay approach, BEAS-2B human bronchial epithelial cells obtained from ATCC were plated at 100,000 cells per well of a 96-well plate one day prior to the experiment. The BEAS-2B assay was run in complete growth medium (bronchial epithelial basal medium plus bulletkit; Lonza; Basel, Switzerland).

Test compounds were serially diluted 1:2 in DMSO and then diluted 1:50 in medium just before use. Diluted compounds were added to the cells, for a final DMSO concentration of 0.2%, and incubated for 30 min (for the TF-1 assay) or 1 hr (for the BEAS-2B assay) at 37Â° C. Then, cells were stimulated with human recombinant cytokine at their respective EC₉₀concentrations, as previously determined for each individual lot. Cells were stimulated with IL-13 (R&D Systems, Minneapolis, Minn.) for 15 min at 37Â° C. The TF-1 cell reactions were stopped by the direct addition of 10Ã— lysis buffer (Cell Signaling Technologies, Danvers, Mass.), whereas the BEAS-2B cell incubations were halted by the removal of medium and addition of 1Ã— lysis buffer. The resultant samples were frozen in the plates at âˆ’80Â° C. Compound mediated inhibition of STAT6 phosphorylation was measured in the cell lysates using MesoScale Discovery (MSD) technology (Gaithersburg, Md.). EC₅₀values were determined as the concentration of compound required for 50% inhibition of STAT phosphorylation relative to that measured for the DMSO control.
