DETAILED DESCRIPTION
I. Overview of Terms

The following explanations of terms and methods are provided to better describe the present disclosure and to guide those of ordinary skill in the art in the practice of the present disclosure. The singular forms “a,” “an,” and “the” refer to one or more than one, unless the context clearly dictates otherwise. The term “or” refers to a single element of stated alternative elements or a combination of two or more elements, unless the context clearly indicates otherwise. As used herein, “comprises” means “includes.” Thus, “comprising A or B,” means “including A, B, or A and B,” without excluding additional elements.

Unless otherwise indicated, all numbers expressing quantities of components, molecular weights, percentages, temperatures, times, and so forth, as used in the specification or claims are to be understood as being modified by the term “about.” Accordingly, unless otherwise indicated, implicitly or explicitly, the numerical parameters set forth are approximations that may depend on the desired properties sought and/or limits of detection under standard test conditions/methods. When directly and explicitly distinguishing embodiments from discussed prior art, the embodiment numbers are not approximates unless the word “about” is expressly recited.

Unless explained otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure pertains. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present disclosure, suitable methods and materials are described below. The materials, methods, and examples are illustrative only and not intended to be limiting.

When chemical structures are depicted or described, unless explicitly stated otherwise, all carbons are assumed to include hydrogen so that each carbon conforms to a valence of four. For example, in the structure on the left-hand side of the schematic below there are nine hydrogen atoms implied. The nine hydrogen atoms are depicted in the right-hand structure.

[Image Omitted]

Sometimes a particular atom in a structure is described in textual formula as having a hydrogen or hydrogen atoms, for example —CH₂CH₂—. It will be understood by a person of ordinary skill in the art that the aforementioned descriptive techniques are common in the chemical arts to provide brevity and simplicity to description of organic structures.

If an R group is depicted as “floating” on a ring system, as for example with R¹in the group:

[Image Omitted]

- then, unless otherwise defined, a substituent R (e.g., R¹above) can reside on any atom of the fused bicyclic ring system, excluding the atom carrying the bond with the “” symbol, so long as a stable structure is formed.

When a group R is depicted as existing on a ring system containing saturated carbons, as for example in the formula:

[Image Omitted]

- where, in this example, y can be more than one, assuming each replaces a currently depicted, implied, or expressly defined hydrogen on the ring; then, unless otherwise defined, two R's can reside on the same carbon. A simple example is when R is a methyl group. The depicted structure can exist as a geminal dimethyl on a carbon of the depicted ring (an “annular” carbon). In another example, two R's on the same carbon, including that same carbon, can be included in a ring, thus creating a spirocyclic ring (a “spirocyclyl” group) structure.

As used herein, the term “substituted” refers to all subsequent modifiers in a term, for example in the term “substituted arylC_1-8alkyl,” substitution may occur on the “C_1-8alkyl” portion, the “aryl” portion or both portions of the arylC_1-8alkyl group.

“Substituted,” when used to modify a specified group or moiety, means that at least one, and perhaps two or more, hydrogen atoms of the specified group or moiety is independently replaced with the same or different substituent groups as defined below. In a particular embodiment, a group, moiety or substituent may be substituted or unsubstituted, unless expressly defined as either “unsubstituted” or “substituted.” Accordingly, any of the groups specified herein may be unsubstituted or substituted unless the context indicates otherwise or a particular structural formula precludes substitution. In particular embodiments, a substituent may or may not be expressly defined as substituted, but is still contemplated to be optionally substituted. For example, an “aliphatic” or a “cyclic” moiety may be unsubstituted or substituted, but an “unsubstituted aliphatic” or an “unsubstituted cyclic” is not substituted.

“Substituents” or “substituent groups” for substituting for one or more hydrogen atoms on saturated carbon atoms in the specified group or moiety can be, unless otherwise specified, —R⁶⁰, halo, ═O, —OR⁷⁰, —SR⁷⁰, —N(R⁸⁰)₂, haloalkyl, perhaloalkyl, —CN, —NO₂, ═N₂, —N₃, —SO₂R⁷⁰, —SO₃⁻M⁺, —SO₃R⁷⁰, —OSO₂R⁷⁰, —OSO₃⁻M⁺, —OSO₃R⁷⁰, —P(O)(O⁻)₂(M⁺)₂, —P(O)(O⁻)₂M²⁺, —P(O)(OR⁷⁰)O⁻M⁺, —P(O)(OR⁷⁰)₂, —C(O)R⁷⁰, —C(S)R⁷⁰, —C(NR⁷⁰)R⁷⁰, —CO₂⁻M⁺, —CO₂R⁷⁰, —C(S)OR⁷⁰, —C(O)N(R⁸⁰)₂, —C(NR⁷⁰)(R⁸⁰)₂, —OC(O)R⁷⁰, —OC(S)R⁷⁰, —OCO₂⁻M⁺, —OCO₂R⁷⁰, —OC(S)OR⁷⁰, —NR⁷⁰C(O)R⁷⁰, —NR⁷⁰C(S)R⁷⁰, —NR⁷⁰CO₂⁻M⁺, —NR⁷⁰CO₂R⁷⁰, —NR⁷⁰C(S)OR⁷⁰, —NR⁷⁰C(O)N(R⁸⁰)₂, —NR⁷⁰C(NR⁷⁰)R⁷⁰and —NR⁷⁰C(NR⁷⁰)N(R⁸⁰)₂, where R⁶⁰is C_1-10aliphatic, heteroaliphatic, or cycloaliphatic, typically, C_1-6aliphatic, more typically C_1-6alkyl, where R⁶⁰optionally may be substituted; each R⁷⁰is independently for each occurrence hydrogen or R⁶⁰; each R⁸⁰is independently for each occurrence R⁷⁰or alternatively, two R groups, taken together with the nitrogen atom to which they are bonded, form a 3- to 7-membered heterocycloaliphatic, which optionally includes from 1 to 4 of the same or different additional heteroatoms selected from O, N and S, of which N optionally has R⁷⁰substitution, such as H or C₁-C₃alkyl substitution; and each M⁺ is a counter ion with a net single positive charge. Each M⁺ is independently for each occurrence, for example, an alkali metal ion, such as K⁺, Na⁺, Li⁺; an ammonium ion, such as ⁺N(R⁶⁰)₄; a protonated amino acid ion, such as a lysine ion, or an arginine ion; or an alkaline metal earth ion, such as [Ca²⁺]_0.5, [Mg²⁺]_0.5, or [Ba²⁺]_0.5(a subscript “0.5” means, for example, that one of the counter ions for such divalent alkali earth ions can be an ionized form of a compound of the disclosure and the other a typical counter ion such as chloride, or two ionized compounds can serve as counter ions for such divalent alkali earth ions, or a doubly ionized compound can serve as the counter ion for such divalent alkali earth ions). As specific examples, —N(R⁸⁰)₂includes —NH₂, —NH-alkyl, —NH-pyrrolidin-3-yl, N-pyrrolidinyl, N-piperazinyl, 4N-methyl-piperazin-1-yl, N-morpholinyl and the like. Any two hydrogen atoms on a single carbon also can be replaced with, for example, ═O, ═NR⁷⁰, ═N—OR⁷⁰, ═N₂or ═S.

Substituent groups for replacing hydrogen atoms on unsaturated carbon atoms in groups containing unsaturated carbons are, unless otherwise specified, —R⁶⁰, halo, —O⁻M⁺, —OR⁷⁰, —SR⁷⁰, —S⁻M⁺, —N(R⁸⁰)₂, perhaloalkyl, —CN, —OCN, —SCN, —NO, —NO₂, —N₃, —SO₂R⁷⁰, —SO₃⁻M⁺, —SO₃R⁷⁰, —OSO₂R⁷⁰, —OSO₃⁻M⁺, —OSO₃R⁷⁰, —PO₃⁻²(M⁺)₂, —PO₃⁻²M²⁺, —P(O)(OR⁷⁰)O⁻M⁺, —P(O)(OR⁷⁰)₂, —C(O)R⁷⁰, —C(S)R⁷⁰, —C(NR⁷⁰)R⁷⁰, —CO₂⁻M⁺, —CO₂R⁷⁰, —C(S)OR⁷⁰, —C(O)NR⁸⁰R⁸⁰, —C(NR⁷⁰)N(R⁸⁰)₂, —OC(O)R⁷⁰, —OC(S)R⁷⁰, —OCO₂⁻M⁺, —OCO₂R⁷⁰, —OC(S)OR⁷⁰, —NR⁷⁰C(O)R⁷⁰, —NR⁷⁰C(S)R⁷⁰, —NR⁷⁰CO₂⁺M⁺, —NR⁷⁰CO₂R⁷⁰, —NR⁷⁰C(S)OR⁷⁰, —NR⁷⁰C(O)N(R⁸⁰)₂, —NR⁷⁰C(NR⁷⁰)R⁷⁰and —NR⁷⁰C(NR⁷⁰)N(R⁸⁰)₂, where R⁶⁰, R⁷⁰, R⁸⁰and M⁺ are as previously defined. In an independent embodiment, the substituents are not —O⁻M⁺, —OR⁷⁰, —SR⁷⁰, or —S⁻M⁺.

In one embodiment, a group that is substituted has at least one substituent up to the number of substituents possible for a particular moiety, such as 1 substituent, 2 substituents, 3 substituents, or 4 substituents.

Additionally, in embodiments where a group or moiety is substituted with a substituted substituent, the nesting of such substituted substituents is limited to three, thereby preventing the formation of polymers. Thus, in a group or moiety comprising a first group that is a substituent on a second group that is itself a substituent on a third group, which is attached to the parent structure, the first (outermost) group can only be substituted with unsubstituted substituents. For example, in a group comprising -(aryl-1)-(aryl-2)-(aryl-3), aryl-3 can only be substituted with substituents that are not themselves substituted.

Any group or moiety defined herein can be connected to any other portion of a disclosed structure, such as a parent or core structure, as would be understood by a person of ordinary skill in the art, such as by considering valence rules, comparison to exemplary species, and/or considering functionality, unless the connectivity of the group or moiety to the other portion of the structure is expressly stated, or is implied by context.

In general, the nature of the carrier will depend on the particular mode of administration being employed. For instance, parenteral formulations usually comprise injectable fluids that include pharmaceutically and physiologically acceptable fluids such as water, physiological saline, balanced salt solutions, aqueous dextrose, glycerol or the like as a vehicle. In some examples, the pharmaceutically acceptable carrier may be sterile to be suitable for administration to a subject (for example, by parenteral, intramuscular, or subcutaneous injection). In addition to biologically-neutral carriers, pharmaceutical compositions to be administered can contain minor amounts of non-toxic auxiliary substances, such as wetting or emulsifying agents, preservatives, and pH buffering agents and the like, for example sodium acetate or sorbitan monolaurate.

“Pharmaceutically acceptable salt” refers to pharmaceutically acceptable salts of a compound that are derived from a variety of organic and inorganic counter ions as will be known to a person of ordinary skill in the art and include, by way of example only, sodium, potassium, calcium, magnesium, ammonium, tetraalkylammonium, and the like; and when the molecule contains a basic functionality, salts of organic or inorganic acids, such as hydrochloride, hydrobromide, tartrate, mesylate, acetate, maleate, oxalate, and the like. “Pharmaceutically acceptable acid addition salts” are a subset of “pharmaceutically acceptable salts” that retain the biological effectiveness of the free bases while formed by acid partners. In particular, the disclosed compounds form salts with a variety of pharmaceutically acceptable acids, including, without limitation, inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like, as well as organic acids such as amino acids, formic acid, acetic acid, trifluoroacetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, benzene sulfonic acid, isethionic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, xinafoic acid and the like. “Pharmaceutically acceptable base addition salts” are a subset of “pharmaceutically acceptable salts” that are derived from inorganic bases such as sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts and the like.

In particular disclosed embodiments, the compounds may be a formate, trifluoroactate, hydrochloride or sodium salt.

“Effective amount” with respect to a compound or pharmaceutical composition refers to an amount of the compound or pharmaceutical composition sufficient to achieve a particular desired result, such as to inhibit a protein or enzyme. In particular embodiments, an “effective amount” is an amount sufficient to inhibit RIP1; to elicit a desired biological or medical response in a tissue, system, subject or patient; to treat a specified disorder or disease; to ameliorate or eradicate one or more of its symptoms; and/or to prevent the occurrence of the disease or disorder. The amount of a compound which constitutes an “effective amount” may vary depending on the compound, the desired result, the disease state and its severity, the size, age, and gender of the patient to be treated and the like, as will be understood by a person of ordinary skill in the art.

“Prodrug” refers to compounds that are transformed in vivo to yield a biologically active compound, or a compound more biologically active than the parent compound. In vivo transformation may occur, for example, by hydrolysis or enzymatic conversion. Common examples of prodrug moieties include, but are not limited to, ester and amide forms of a compound having an active form bearing a carboxylic acid moiety. Examples of pharmaceutically acceptable esters of the compounds of this disclosure include, but are not limited to, esters of phosphate groups and carboxylic acids, such as aliphatic esters, particularly alkyl esters (for example C_1-6alkyl esters ). Other prodrug moieties include phosphate esters, such as —CH₂—O—P(O)(OR′)₂or a salt thereof, wherein R′ is H or C_1-6alkyl.

Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference for all purposes.

“Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of a solute. The solvent can be an organic solvent, an inorganic solvent, or a mixture of both. Exemplary solvents include, but are not limited to, alcohols, such as methanol, ethanol, propanol; amides such as N,N-dialiphatic amides, such as N,N-dimethylformamide; tetrahydrofuran; alkylsulfoxides, such as dimethylsulfoxide; water; and combinations thereof. The compounds described herein can exist in un-solvated as well as solvated forms when combined with solvents, pharmaceutically acceptable or not, such as water, ethanol, and the like. Solvated forms of the presently disclosed compounds are within the scope of the embodiments disclosed herein.

“Sulfonamide” refers to the group or moiety —SO₂amino, or —N(R)sulfonyl, where R is H, aliphatic, heteroaliphatic, or aromatic (including both aryl and heteroaryl).

“Sulfanyl” refers to the group or —SH, —S-aliphatic, —S-heteroaliphatic, —S-aromatic, (including both-S-aryl and —S-heteroaryl).

“Sulfinyl” refers to the group or moiety —S(O)H, —S(O)aliphatic, —S(O)heteroaliphatic, or —S(O)aromatic (including both —S(O)aryl and —S(O)heteroaryl).

“Treating” or “treatment” as used herein concerns treatment of a disease or condition of interest in a patient or subject, particularly a human having the disease or condition of interest, and includes by way of example, and without limitation:

- (i) preventing the disease or condition from occurring in a patient or subject, in particular, when such patient or subject is predisposed to the condition but has not yet been diagnosed as having it;
- (ii) inhibiting the disease or condition, for example, arresting or slowing its development;
- (iii) relieving the disease or condition, for example, causing diminution of a symptom or regression of the disease or condition or a symptom thereof, or
- (iv) stabilizing the disease or condition.

As used herein, the terms “disease” and “condition” can be used interchangeably or can be different in that the particular malady or condition may not have a known causative agent (so that etiology has not yet been determined) and it is therefore not yet recognized as a disease but only as an undesirable condition or syndrome, where a more or less specific set of symptoms have been identified by clinicians.

The above definitions and the following general formulas are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluoro groups). Such impermissible substitution patterns are easily recognized by a person having ordinary skill in the art.

A person of ordinary skill in the art will appreciate that compounds may exhibit the phenomena of tautomerism, conformational isomerism, geometric isomerism, and/or optical isomerism. For example, certain disclosed compounds can include one or more chiral centers and/or double bonds and as a consequence can exist as stereoisomers, such as double-bond isomers (i.e., geometric isomers), enantiomers, diasteromers, and mixtures thereof, such as racemic mixtures. As another example, certain disclosed compounds can exist in several tautomeric forms, including the enol form, the keto form, and mixtures thereof. As the various compound names, formulae and compound drawings within the specification and claims can represent only one of the possible tautomeric, conformational isomeric, optical isomeric, or geometric isomeric forms, a person of ordinary skill in the art will appreciate that the disclosed compounds encompass any tautomeric, conformational isomeric, optical isomeric, and/or geometric isomeric forms of the compounds described herein, as well as mixtures of these various different isomeric forms. Mixtures of different isomeric forms, including mixtures of enantiomers and/or stereoisomers, can be separated to provide each separate enantiomers and/or stereoisomer using techniques known to those of ordinary skill in the art, particularly with the benefit of the present disclosure. In cases of limited rotation, e.g. around the amide bond or between two directly attached rings such as pyridinyl rings, biphenyl groups, and the like, atropisomers are also possible and are also specifically included in the compounds of the disclosure.

In any embodiments, any or all hydrogens present in the compound, or in a particular group or moiety within the compound, may be replaced by a deuterium or a tritium. Thus, a recitation of alkyl includes deuterated alkyl, where from one to the maximum number of hydrogens present may be replaced by deuterium. For example, ethyl refers to both C₂H₅or C₂H₅where from 1 to 5 hydrogens are replaced by deuterium, such as in C₂D_xH_5-x.

With reference to Scheme 1, protected amine precursor 100 can be coupled with R¹group 102, which comprises an “R⁶-linker” group as illustrated in Scheme 1, using a metal-mediated, cross-coupling reaction to provide the cross-coupled product 104. In some embodiments, the metal-mediated, cross-coupling reaction can be carried out using a transition metal catalyst, such as a palladium catalyst. Exemplary palladium catalysts include, but are not limited to, Pd(O) catalysts (e.g., Pd₂(dba)₃, Pd(dba)₂, Pd(PPh₃)₄, and the like) or Pd(II) catalyst (e.g., XPhos Pd generation 2 or generation 3, PdCl₂, Pd(OAc)₂, and the like). In some embodiments, the palladium catalyst can be used in combination with another co-catalyst, such as CuI, to promote the cross-coupling reaction, such as in a Sonogoshira reaction. The metal-mediated, cross-coupling also can comprise using a base, such as an amine base (e.g., Et₃N), or an inorganic base (e.g., Cs₂CO₃, Na₂CO₃, K₂CO₃or the like), and a solvent (e.g., dimethylformamide). With reference to Scheme 1, X is a suitable group for metal-mediated, cross-coupling, such as a halogen or a triflate group and PG is an amine protecting group, which can be selected from, but is not limited to, a 9-fluorenylmethoxycarbonyl (“Fmoc”) group, a t-butyloxycarbonyl (“Boc”) group, a trityl (“Tr”) group, an allyloxycarbonyl (“Alloc”) group, a benzyloxycarbonyl (“Cbz”) group, and the like.

Representative examples of the method steps shown in Scheme 1 are provided below in Schemes 2A-2F. A method similar to that illustrated in Scheme 2A can be used to make other compound embodiments disclosed herein by replacing the propargylic alcohol in Scheme 2A with the corresponding alkyne group that gives rise to such compounds; the further modifications that can be used to arrive at the final structure of such compounds are discussed below.

Once cross-coupled product 104 is made, it can be subjected to an optional linker group reduction step wherein linker groups comprising one or more sites of unsaturation can be reduced to saturated linker groups and/or linker groups having fewer degrees of unsaturation. If a linker reduction group is used, it can then be followed by a deprotection step and then an amide formation step, as illustrated in Scheme 3. Alternatively, if a linker group reduction step is not used, then cross-coupled product 104 can be deprotected and converted to amide compound 302.

[Image Omitted]

With reference to Scheme 3, an optional linker reduction step can be carried out. For example, if the linker comprises a site of unsaturation (e.g., a double or triple bond), the site of unsaturation can be reduced such that it becomes fully saturated (e.g., such as reducing a double bond and/or a triple bond to a single bond) or that it has few degrees of unsaturation (e.g., such as reducing a triple bond to a double bond). Suitable reagents for carrying out such an optional linker reduction step are recognized by those of ordinary skill in the art with the benefit of the present disclosure; however, one exemplary set of conditions includes exposing cross-coupled product 104 to H₂in the presence of Pd on carbon. As these steps are optional, they need not be carried out in all embodiments. Instead, in some embodiments, cross-coupled product 104 can be deprotected to provide an amine that is then converted to amide compound 302 by reacting the amine with a suitable acid coupling partner 300, as illustrated in Scheme 3.

Representative examples of the method steps shown in Scheme 3 are provided below in Schemes 4A-4D. A method similar to that described in Scheme 4A can be used to make other compounds disclosed herein. Certain compounds can be further functionalized as discussed below.

In some embodiments, the method can further comprise making one or more additional modifications to amide compound 302 to provide amide compound 500, such as modifying an R⁶group to form a different R⁶group, as illustrated in Scheme 5.

[Image Omitted]

With reference to Scheme 5, one or more modifications to the R⁶group can be carried out. For example, if R⁶is an ester group, it can be converted to a carboxylic acid or to a primary alcohol. Suitable reagents for carrying out such an optional modification step are recognized by those of ordinary skill in the art with the benefit of the present disclosure; however, one exemplary set of conditions includes exposing an R⁶ester group to LiOH to provide the corresponding acid. The resulting acid can even be further modified to provide an amide-containing product by using suitable amide coupling conditions (such as those described above) in combination with an amine coupling partner. Similar methods can be used to make compound embodiments disclosed herein (wherein the double bond of the linker group is not first reduced prior to coupling). In yet additional embodiments, compound embodiments comprising an alkyne with a terminal OH group can be made by converting the terminal alcohol obtained in the above-described methods into a functionalized alcohol.

A number of the exemplary disclosed compounds are alkynyl substituted analogs. These compounds can be made using a metal-mediated coupling strategy as discussed above with reference to Scheme 1. Scheme 6 illustrates a more detailed general method for making alkynyl substituted analogs according to the present disclosure.

With reference to Scheme 6, nitrogen is bubbled through a stirring solution of an aryl halide (1 equivalent), either compound 700, CuI (0.1-0.2 equivalent), and Pd(PPh₃)₄(0.05-0.1 equivalent) in dry DMF (3-4 mL/mmol) for 3 minutes in a vial. Subsequently, to the dark reaction solution is added NEt₃(10 equivalents), followed by the corresponding alkyne (1.5-3 equivalents), compound 702, in quick succession. Nitrogen is bubbled through the reaction mixture for 2 minutes, and the vial is capped. The reaction mixture is stirred at an effective reaction temperatures, such as 70-90° C., for an effective reaction period, such as 3-6 hours. Alternatively, the reaction mixture can be heated in a microwave reactor (30-45 minutes) until the aryl halide 700 is consumed. The dark reaction solution is processed by one of the following methods: a) a work-up of diluting with ice-water/organic solvent; b) concentrating to dryness, followed by a work-up after diluting with ice-water/organic solvent; or c) the crude residue is diluted with ice-water, sonicated and the slurry allowed to warm to room temperature. The resulting grey/dark solid is collected by filtration, suction dried, dissolved in THF (20 mL), filtered through Celite®/silica gel pad, and the pad is washed with THF. Subsequently, the crude material is purified by reverse phase column chromatographic or by normal phase silica gel flash column chromatography to provide corresponding the alkynyl substituted analogs (Yield: 25-69%), compound 704.

Examples of allergic disorders that may be treated using the disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, include, but are not limited to, asthma (e.g. atopic asthma, allergic asthma, atopic bronchial IgE-mediated asthma, non-atopic asthma, bronchial asthma, non-allergic asthma, essential asthma, true asthma, intrinsic asthma caused by pathophysiologic disturbances, essential asthma of unknown or unapparent cause, emphysematous asthma, exercise-induced asthma, emotion-induced asthma, extrinsic asthma caused by environmental factors, cold air induced asthma, occupational asthma, infective asthma caused by or associated with bacterial, fungal, protozoal, or viral infection, incipient asthma, wheezy infant syndrome, bronchiolitis, cough variant asthma or drug-induced asthma), allergic bronchopulmonary aspergillosis (ABPA), allergic rhinitis, perennial allergic rhinitis, perennial rhinitis, vasomotor rhinitis, post-nasal drip, purulent or non-purulent sinusitis, acute or chronic sinusitis, and ethmoid, frontal, maxillary, or sphenoid sinusitis.

As another example, rheumatoid arthritis (RA) typically results in swelling, pain, loss of motion and tenderness of target joints throughout the body. RA is characterized by chronically inflamed synovium that is densely crowded with lymphocytes. The synovial membrane, which is typically one cell layer thick, becomes intensely cellular and assumes a form similar to lymphoid tissue, including dendritic cells, T-, B- and NK cells, macrophages and clusters of plasma cells. This process, as well as a plethora of immunopathological mechanisms including the formation of antigen-immunoglobulin complexes, eventually result in destruction of the integrity of the joint, resulting in deformity, permanent loss of function and/or bone erosion at or near the Joint. The disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, may be used to treat, ameliorate or prevent any one, several or all of these symptoms of RA. Thus, in the context of RA, the compounds are considered to provide therapeutic benefit when a reduction or amelioration of any of the symptoms commonly associated with RA is achieved, regardless of whether the treatment results in a concomitant treatment of the underlying RA and/or a reduction in the amount of circulating rheumatoid factor (“RF”).

The American College of Rheumatology (ACR) has developed criteria for defining improvement and clinical remission in RA. Once such parameter, the ACR20 (ACR criteria for 20% clinical improvement), requires a 20% improvement in the tender and swollen joint count, as well as a 20% improvement in 3 of the following 5 parameters: patient's global assessment, physician's global assessment, patient's assessment of pain, degree of disability, and level of acute phase reactant. These criteria have been expanded for 50% and 70% improvement in ACR50 and ACR70, respectively. Other criteria include Paulu's criteria and radiographic progression (e.g. Sharp score).

In some embodiments, therapeutic benefit in patients suffering from RA is achieved when the patient exhibits an ACR20. In specific embodiments, ACR improvements of ACRC50 or even ACR70 may be achieved.

In one embodiment, the presently disclosed compounds can be used to slow the onset of the consequences of aging. For example, the present compounds reduce the heightened chronic inflammation associated with advanced age (“inflammaging”). Myriad symptoms and conditions are associated with inflammaging, by way of example, such conditions that can be treated with the present compounds include, neurodegenerative disorders, such as Parkinson's and Alzheimer's, hematopoietic neoplasms and myeloproliferative disorders. Additional conditions that can be treated or ameliorated by the present compounds include those described by Franceschi C, Campisi J. Chronic inflammation (inflammaging) and its potential contribution to age-associated diseases. J Gerontol A Biol Sci Med Sci. 2014; 69 Suppl 1:S4-S9. In another aspect, the present compounds can be used to reduce aging effects on the reproductive system. For example, necroptosis induced by RIP1 signaling has been implicated in the aging of reproductive organs by Li et al. eLife 2017; 6:e27692 and Chaudhary et al. Journal of Biomedical Science (2019) 26:11, thus the present compounds could be used to treat symptoms of associated with aging, such as reduced testosterone levels, reduced fertility and prostate hyperplasia.

The present compounds can be used to treat disorders such as cancers, leukemias and lymphomas in combination with the standard of care. By way of example, myelodysplastic syndrome (MDS) can be treated with a compound disclosed herein along with the standard of care.

B. Formulations and Administration

Pharmaceutical compositions comprising one or more active compounds of the disclosure may be manufactured by any suitable method, such as mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilization processes. The pharmaceutical compositions may be formulated using one or more physiologically acceptable excipients (e.g., diluents, carriers, or auxiliaries), one or more adjuvants, or combinations thereof to provide preparations which can be used pharmaceutically.

The active compound(s) may be formulated in the pharmaceutical compositions per se, or in the form of a pharmaceutically acceptable salt, a stereoisomer, an N-oxide, a tautomer, a hydrate, a solvate, an isotope, or a prodrug thereof. Typically, such salts are more soluble in aqueous solutions than the corresponding free acids and bases, but salts having lower solubility than the corresponding free acids and bases may also be formed.

Pharmaceutical compositions of the disclosure may take a form suitable for virtually any mode of administration, including, for example, topical, ocular, oral, buccal, systemic, nasal, injection, such as i.v. or i.p., transdermal, rectal, vaginal, etc., or a form suitable for administration by inhalation or insufflation.

For topical administration, the active compound(s), pharmaceutically acceptable salt, stereoisomer, N-oxide, tautomer, hydrate, solvate, isotope, or prodrug may be formulated as solutions, gels, ointments, creams, suspensions, etc. as are well-known in the art.

Systemic formulations include those designed for administration by injection, e.g., subcutaneous, intravenous, intramuscular, intrathecal or intraperitoneal injection, as well as those designed for transdermal, transmucosal oral or pulmonary administration.

Useful injectable preparations include sterile suspensions, solutions or emulsions of the active compound(s) in aqueous or oily vehicles. The pharmaceutical compositions may also contain formulating agents, such as suspending, stabilizing and/or dispersing agent. The formulations for injection may be presented in unit dosage form, e.g., in ampules or in multidose containers, and may contain added preservatives.

Alternatively, the injectable formulation may be provided in powder form for reconstitution with a suitable vehicle, including but not limited to sterile, pyrogen-free water, buffer, dextrose solution, etc., before use. To this end, the active compound(s) maybe dried by any art-known technique, such as lyophilization, and reconstituted prior to use.

For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are known in the art.

For oral administration, the pharmaceutical compositions may take the form of, for example, lozenges, tablets or capsules prepared by conventional means with pharmaceutically acceptable excipients, such as: binding agents (e.g., pregelatinised maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or silica); disintegrants (e.g., potato starch or sodium starch glycolate); and/or wetting agents (e.g., sodium lauryl sulfate). The tablets may be coated by methods well known in the art with, for example, sugars, films or enteric coatings.

Liquid preparations for oral administration may take the form of, for example, elixirs, solutions, syrups or suspensions, or they may be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations may be prepared by conventional means with pharmaceutically acceptable excipients such as: suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol, Cremophore™ or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid). The preparations may also contain buffer salts, preservatives, flavoring, coloring and sweetening agents as appropriate.

Preparations for oral administration may be suitably formulated to give controlled release of the active compound, as is well known.

For buccal administration, the pharmaceutical compositions may take the form of tablets or lozenges formulated in conventional manner.

For rectal and vaginal routes of administration, the active compound(s) may be formulated as solutions (for retention enemas) suppositories or ointments containing conventional suppository bases, such as cocoa butter or other glycerides.

For nasal administration or administration by inhalation or insufflation, the active compound(s), pharmaceutically acceptable salt, stereoisomer, N-oxide, tautomer, hydrate, solvate, isotope, or prodrug can be conveniently delivered in the form of an aerosol spray from pressurized packs or a nebulizer with the use of a suitable propellant, e.g.,) dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, fluorocarbons, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges for use in an inhaler or insufflator (for example capsules and cartridges comprised of gelatin) may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.

A specific example of an aqueous suspension formulation suitable for nasal administration using commercially-available nasal spray devices includes the following ingredients: active compound (0.5 20 mg/ml); benzalkonium chloride (0.1 0.2 mg/mL); polysorbate 80 (TWEEN® 80; 0.5 5 mg/ml); carboxymethylcellulose sodium or microcrystalline cellulose (1 15 mg/ml); phenylethanol (1 4 mg/ml); and dextrose (20 50 mg/ml). The pH of the final suspension can be adjusted to range from about pH 5 to pH 7, with a pH of about pH 5.5 being typical.

Another specific example of an aqueous suspension suitable for administration of the compounds via inhalation contains 20 mg/mL of the disclosed compound(s), 1% (v/v) polysorbate 80 (TWEEN® 80), 50 mM citrate and/or 0.9% sodium chloride.

For ocular administration, the active compound(s) may be formulated as a solution, emulsion, suspension, etc. suitable for administration to the eye. A variety of vehicles suitable for administering compounds to the eye are known in the art. Specific non-limiting examples are described in U.S. Pat. Nos. 6,261,547; 6,197,934; 6,056,950; 5,800,807; 5,776,445; 5,698,219; 5,521,222; 5,403,841; 5,077,033; 4,882,150; and 4,738,851, which are incorporated herein by reference.

For prolonged delivery, the active compound(s) can be formulated as a depot preparation for administration by implantation or intramuscular injection. The active ingredient maybe formulated with suitable polymeric or hydrophobic materials (e.g., as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, e.g., as a sparingly soluble salt. Alternatively, transdermal delivery systems manufactured as an adhesive disc or patch which slowly releases the active compound(s) for percutaneous absorption may be used. To this end, permeation enhancers may be used to facilitate transdermal penetration of the active compound(s). Suitable transdermal patches are described in for example, U.S. Pat. Nos. 5,407,713; 5,352,456; 5,332,213; 5,336,168; 5,290,561; 5,254,346; 5,164,189; 5,163,899; 5,088,977; 5,087,240; 5,008,110; and 4,921,475, which are incorporated herein by reference.

Alternatively, other pharmaceutical delivery systems may be employed. Liposomes and emulsions are well-known examples of delivery vehicles that may be used to deliver active compound(s). Certain organic solvents, such as dimethylsulfoxide (DMSO), may also be employed, although usually at the cost of greater toxicity.

The pharmaceutical compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active compound(s). The pack may, for example, comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration.

Several approaches exist for transporting molecules across the blood brain barrier. These include, but are not limited to physical methods, lipid-based methods, and receptor and channel-based methods. Physical methods of transporting a compound across the blood-brain barrier include, but are not limited to, circumventing the blood-brain barrier entirely, and/or creating openings in the blood-brain barrier. Circumvention methods include, but are not limited to, direct injection (e.g., Papanastassiou et al., Gene Therapy 9:398-406, 2002), interstitial infusion/convection enhanced delivery (Bobo et al., Proc. Natl. Acad. Sci. U.S.A. 91:2076-2080, 1994), and implanting a delivery device in the brain (see, e.g., Gill et al., Nature Med. 9:589-595, 2003. Openings in the blood-brain barrier include, but are not limited to, ultrasound, osmotic pressure (e.g., by administration of hypertonic mannitol and permeabilization by, e.g., bradykinin or permeabilizer A-7 (see, e.g., U.S. Pat. Nos. 5,112,596, 5,268,164, 5,506,206, and 5,686,416). Compounds also may be encapsulated in liposomes that are coupled to antibody binding fragments that bind to receptors on the vascular endothelium of the blood-brain barrier.

For certain embodiments, the compounds can be administered continuously by infusion into the fluid reservoirs of the CNS or by bolus injection. Compounds can be administered using an indwelling catheter and a continuous administration means such as a pump, or by Implantation of a sustained-release vehicle. For example, the compounds may be injected through chronically implanted cannulas or chronically infused with the help of osmotic minipumps. Subcutaneous pumps can deliver compounds to the cerebral ventricles.

C. Dosages

The disclosed compound, pharmaceutical compositions, or combinations of disclosed compounds will generally be used in an amount effective to achieve the intended result, for example, in an amount effective to inhibit a RIP1 kinase and/or to treat, prevent or ameliorate a particular condition. The disclosed compound(s), or pharmaceutical compositions thereof, can be administered therapeutically to achieve therapeutic benefit or prophylactically to achieve a prophylactic benefit. Therapeutic benefit means eradication or amelioration of the underlying disorder being treated and/or eradication or amelioration of one or more of the symptoms associated with the underlying disorder such that the patient reports an improvement in feeling or condition, notwithstanding that the patient may still be afflicted with the underlying disorder. For example, administration of a compound to a patient suffering from an allergy provides therapeutic benefit not only when the underlying allergic response is eradicated or ameliorated, but also when the patient reports a decrease in the severity or duration of the symptoms associated with the allergy following exposure to the allergen. As another example, therapeutic benefit in the context of asthma includes an improvement in respiration following the onset of an asthmatic attack or a reduction in the frequency or severity of asthmatic episodes. Therapeutic benefit also includes halting or slowing the progression of the disease, regardless of whether improvement is realized.

As known by those of ordinary skill in the art, the preferred dosage of disclosed compounds may depend on various factors, including the age, weight, general health, and severity of the condition of the patient or subject being treated. Dosage also may need to be tailored to the sex of the individual and/or the lung capacity of the individual, when administered by inhalation. Dosage may also be tailored to individuals suffering from more than one condition or those individuals who have additional conditions that affect lung capacity and the ability to breathe normally, for example, emphysema, bronchitis, pneumonia, respiratory distress syndrome, chronic obstructive pulmonary disease, and respiratory infections. Dosage, and frequency of administration of the disclosed compound(s) or pharmaceutical compositions thereof, will also depend on whether the disclosed compound(s) are formulated for treatment of acute episodes of a condition or for the prophylactic treatment of a disorder. A person of ordinary skill in the art will be able to determine the optimal dose for a particular individual.

For prophylactic administration, the disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, can be administered to a patient or subject at risk of developing one of the previously described conditions. For example, if it is unknown whether a patient or subject is allergic to a particular drug, the disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, can be administered prior to administration of the drug to avoid or ameliorate an allergic response to the drug. Alternatively, prophylactic administration can be used to avoid or ameliorate the onset of symptoms in a patient diagnosed with the underlying disorder. For example, a disclosed compound(s), or pharmaceutical composition thereof, can be administered to an allergy sufferer prior to expected exposure to the allergen. A disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, can also be administered prophylactically to healthy individuals who are repeatedly exposed to agents known to one of the above-described maladies to prevent the onset of the disorder. For example, a disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, can be administered to a healthy individual who is repeatedly exposed to an allergen known to induce allergies, such as latex, in an effort to prevent the individual from developing an allergy. Alternatively, a disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, can be administered to a patient suffering from asthma prior to partaking in activities which trigger asthma attacks to lessen the severity of, or avoid altogether, an asthmatic episode.

Effective dosages can be estimated initially from in vitro assays. For example, an initial dosage for use in subjects can be formulated to achieve a circulating blood or serum concentration of active compound that is at or above an IC₅₀or EC₅₀of the particular compound as measured in an in vitro assay. Dosages can be calculated to achieve such circulating blood or serum concentrations taking into account the bioavailability of the particular compound. Fingl & Woodbury, “General Principles,” In: Goodman and Gilman's The Pharmaceutical Basis of Therapeutics, Chapter 1, pages 1-46, Pergamon Press, and the references cited therein, provide additional guidance concerning effective dosages.

In some embodiments, the disclosed compounds have an EC₅₀from greater than 0 to 20 μM, such as from greater than 0 to 10 μM, from greater than 0 to 5 μM, from greater than 0 to 1 μM, from greater than 0 to 0.5 μM, from greater than 0 to 0.1 μM, or from greater than 0 to 0.05 μM.

Initial dosages can also be estimated from in vivo data, such as animal models. Animal models useful for testing the efficacy of compounds to treat or prevent the various diseases described above are well-known in the art. Suitable animal models of hypersensitivity or allergic reactions are described in Foster, (1995) Allergy 50(21Suppl):6-9, discussion 34-38 and Tumas et al., (2001), J. Allergy Clin. Immunol. 107(6):1025-1033. Suitable animal models of allergic rhinitis are described in Szelenyi et al., (2000), Arzneimittelforschung 50(11):1037-42; Kawaguchi et al., (1994), Clin. Exp. Allergy 24(3):238-244 and Sugimoto et al., (2000), Immunopharmacology 48(1):1-7. Persons of ordinary skill in the art can adapt such information to determine dosages suitable for human administration.

In some embodiments, assays suitable for determining RIP1 activity can be used. Such assay methods can be used to evaluate the efficacy of compound embodiments disclosed herein and/or that can be used to determine amounts/dosages of the compound embodiments that can provide a desired efficacy. In some embodiments, the assay can be an ADP-Glo™ assay that assesses the ability of a compound embodiment to inhibit RIP1. In other embodiments, whole cell assays using mouse and/or human cells, such as U937 and/or L929 cell necroptosis assays, can be performed to determine safe and effective doses of compounds that can be used in human in vivo studies. Using these whole cell assays, the compound's activity against human and/or murine RIP1 can be assessed in an in vitro context, which then allows a person of ordinary skill in the art to determine safe and effective dosages for in vivo use. Yet another assay that can be used to evaluate the activity of compound embodiments described herein to treat a disease or condition involving RIP1 is an acute hypothermia mouse model, which assesses the compound's ability to inhibit TNF-alpha induced hypothermia. Each of these assays, and various results from using these assays, are described in detail in the Examples section of the present disclosure.

Dosage amounts of disclosed compounds will typically be in the range of from greater than 0 mg/kg/day, such as 0.0001 mg/kg/day or 0.001 mg/kg/day or 0.01 mg/kg/day, up to at least about 100 mg/kg/day. More typically, the dosage (or effective amount) may range from about 0.0025 mg/kg to about 1 mg/kg administered at least once per day, such as from 0.01 mg/kg to about 0.5 mg/kg or from about 0.05 mg/kg to about 0.15 mg/kg. The total daily dosage typically ranges from about 0.1 mg/kg to about 5 mg/kg or to about 20 mg/kg per day, such as from 0.5 mg/kg to about 10 mg/kg per day or from about 0.7 mg/kg per day to about 2.5 mg/kg/day. Dosage amounts can be higher or lower depending upon, among other factors, the activity of the disclosed compound, its bioavailability, the mode of administration, and various factors discussed above.

Dosage amount and dosage interval can be adjusted for individuals to provide plasma levels of the disclosed compound that are sufficient to maintain therapeutic or prophylactic effect. For example, the compounds can be administered once per day, multiple times per day, once per week, multiple times per week (e.g., every other day), one per month, multiple times per month, or once per year, depending upon, amongst other things, the mode of administration, the specific indication being treated, and the judgment of the prescribing physician. Persons of ordinary skill in the art will be able to optimize effective local dosages without undue experimentation.

Pharmaceutical compositions comprising one or more of the disclosed compounds typically comprise from greater than 0 up to 99% of the disclosed compound, or compounds, and/or other therapeutic agent by total weight percent. More typically, pharmaceutical compositions comprising one or more of the disclosed compounds comprise from about 1 to about 20 total weight percent of the disclosed compound and other therapeutic agent, and from about 80 to about 99 weight percent of a pharmaceutically acceptable excipient. In some embodiments, the pharmaceutical composition can further comprise an adjuvant.

Preferably, the disclosed compound, combinations of disclosed compounds, or pharmaceutical compositions thereof, will provide therapeutic or prophylactic benefit without causing substantial toxicity. Toxicity of the disclosed compound can be determined using standard pharmaceutical procedures. The dose ratio between toxic and therapeutic (or prophylactic) effect is the therapeutic index. Disclosed compounds that exhibit high therapeutic indices are preferred.

Example 10

In this example, compounds of the disclosure were evaluated using a biochemical assay using the ADP-Glo™ technology.

ADP-Glo™ (Promega, Madison, WI, USA) reagents were thawed at ambient temperature. Kinase Detection Reagent was prepared by mixing kinase detection buffer with the lyophilized kinase detection substrate.

A 500 ml stock volume of 5×Reaction Kinase Buffer was made by mixing 1000 μl of 1M MgCl₂, 500 μl of 1M Tris-HCL pH7.4, 0.5 mg/ml (25 mg) of BSA, and 3475 μl of distilled H₂O. A 3 ml 2× working stock volume of Reaction Kinase Buffer was made containing a final concentration of 100 μM DTT and 4 mM MnCl₂.

Components of RIPK1 enzyme (Rigel Pharmaceuticals, South San Francisco, CA, USA) were thawed on ice. Diluted RIPK1 was prepared in 1×Kinase Reaction Buffer (diluted from 2× buffer) to 31 ng/well. A 166 M working stock ATP assay solution was prepared in 1×× Kinase Reaction Buffer (diluted from 2×× buffer).

Compounds were serially diluted in DMSO from 250 uM in 4-fold dilutions then diluted 1:5 in 2× Reaction Buffer in a 96 well plate. 1.0 ul of diluted compound was added to a 384 well plate in duplicate. 2 μl of diluted Active RIPK1 was added to 384 well plate (do not add to column1) add 2×rxn buffer to column 1. AKT (Anaspec, Fremont, CA, USA) at 150 nM was combined with ATP working stock at equal volume and 2 ul/well were added to the 384 well plate. The final reaction volume was 5.0 μl.

The plate was quickly centrifuged and the reaction was incubated at 30° C. for 30 minutes. Adding 5 μl of ADP-Glo™ terminated the reaction. The plate was quickly centrifuged and the reaction was incubated at room temperature for 40 minutes. Kinase Detection Reagent was then added and incubated at room temperature for 30 minutes. The relative light unit (RLU) of kinase reaction was determined by luminescent (Luminescence 0.1 s) using a Wallac Victor2 Luminometer (PerkinElmer, Waltham, MA, USA). IC₅₀values obtained from this example are provided by Table 1.

Example 11

In this example, U937 and L929 cells were exposed to compounds of the present disclosure and a cell necroptosis assay was conducted to evaluate the compounds' activity against human RIP1 and murine RIP1.

U937 and L929 cells were obtained from the American Type Culture Collection (Manassa, VA, USA). Both cells were maintained in logarithmic growth phase in complete RPMI 1640 media (Sigma, ST Louis, MO, USA) supplemented with 10% fetal bovine serum (Sigma, ST Louis, MO, USA) at 37° C. with 5% CO₂. For necroptosis assay, L929 cells were plated for 18 h in 100 μL/well medium at 10K cells/well in Costar 96-well black clear-bottom plates (Fisher Scientific, Hampton, NH, USA); U937 cells were plated on the day of the assay in 50 μL/well medium containing 60 uM zVAD-fmk (Lonza, Basel, Switzerland) at 50K cells/well. Medium from L929 cells were removed from the 96-well plates and replaced with 50 μL/well new medium containing 40 uM zVAD-fmk. Each compound of the present disclosure evaluated in this example was serially diluted in DMSO from 2.5 mM in 4-fold dilutions, and then diluted 1:125 in complete medium. 50 μL/well 2× of the compound was then added to the cells in the plates. The cells were pre-incubated with the compound for 1 hour at 37° C. with 5% CO₂and before addition of 10 μL/well 11×TNFα (Peprotech, Rocky Hill, NJ, USA) to give a final concentration of 2 ng/mL for TNFa. The relative amount of necroptosis cells was determined by luminescent using a Wallac Victor2 Luminometer (PerkinElmer, Waltham, MA, USA) and a CellTiter-Glo® Luminescent Cell Viability Reagent Assay (Promega, Madison, WI, USA) added per manufacturer instructions after 18 hours of TNFa stimulation at 37° C. with 5% CO₂. Results from this example are summarized in Table 2. This example establishes that embodiments of the compounds described herein have unexpectedly potent activity against human RIP1 and murine RIP1, which allows their assessment in in vivo mouse models of disease. These results are useful in determining safe and effective doses for humans.

Example 12

In this example, an acute hypothermia mouse model assay is used to evaluate the ability of compounds disclosed herein to inhibit TNF-alpha induced hypothermia.

Female C₅₇BL/6 mice are randomly grouped and weighed on Day −1. On the day of the study (Day 0), mice are administered vehicle or test article by oral gavage. Fifteen minutes after oral administration of test agents, each mouse is administered an intraperitoneal (IP) injection of solution containing recombinant human tumor necrosis factor alpha (TNF-a, 25.0 μg) and zVAD-FMK (200 μg). Body temperature is measured at 0 hours (before IP injections) and every hour via rectal probe temperature measuring device. Three (3) hours after IP injections of TNF-α and zVAD/FMK, mice are euthanized by CO₂asphyxiation and blood is collected via cardiac puncture. Serum and plasma are harvested for determination of cytokine and compound levels, respectively. Separate groups of mice (satellite mice) are included for the determination of compound levels in plasma at the time of administration of TNFa/zVAD-FMK.
