DESCRIPTION

0002 The subject invention was made with government support under a research project supported by NOAA Grant No. NA36RG0537. The government has certain rights in this invention.

FIELD OF THE INVENTION 0003 The subject invention pertains to compounds which are useful as anti-inflammatory agents and to compositions containing such compounds as active ingredients. More particularly, the invention concerns novel biologically active bis-heterocyclic compounds, e.g. bis-indoles, novel uses of the compounds, pharmaceutical compositions containing these compounds, and methods of producing the compounds. The novel uses of the compounds relate to the anti-neurogenic inflammatory properties of the disclosed bis-heterocyclic compounds. Specifically exemplified herein are dragmacidin f, topsentin d and topsentin e, and their salts, analogs and derivatives.

BACKGROUND OF THE INVENTION 0004 The prevention and control of inflammation is often of great importance for the treatment of humans and animals. Much research has been devoted to development of compounds having anti-inflammatory properties. Certain methods and chemical compositions have been developed which aid in inhibiting or controlling inflammation, but additional anti-inflammatory methods and compositions are needed. 0005 It has been found that some natural products and organisms are potential sources for chemical molecules having useful biological activity of great diversity. Marine sponges have proved to be such a source, and a number of publications have issued disclosing organic compounds derived from marine sponges. Such publications include Scheuer, P. J. Ed.

For example, bis-heterocyclic compounds such as bis-indoles have been previously described as having antimicrobial, antitumor or antiviral activity. Specifically, the bis-indole compounds known as topsentins are disclosed in U.S. Pat. No. 4,866,084. Dragmacidin and its related compounds isolated from the marine sponge of the Dragmacidon sp. are disclosed in U.S. Pat. No.4,895,844. These patents are herein incorporated by reference. These compounds as well as the homocarbonyl topsentins and hamacanthins have also been described as having inhibitory activity against cellular inflammatory responses. See U.S. Pat. Nos. 5,290,777 and 5,464,835, which are also hereby incorporated by reference. The present invention provides additional related compounds which have improved water solubility characteristics and which have a novel utility as anti-neurogenic inflammatory compositions. 0008 Other advantages and further scope of applicability of the present invention will become apparent from the detailed descriptions given herein; it should be understood, however, that the detailed descriptions, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent from such descriptions.

BRIEF SUMMARY OF THE INVENTION 0009 The objects of the present invention are accomplished by the provision of novel anti-inflammatory bis-heterocyclic compounds that have a general structure according to the formula:

A1MA2

0010 wherein each of A1 and A2is a heterocycle; and M is a core moiety linking the heterocycles, A1 and A2. In a specific embodiment, the compound comprises an indole as the A1 and A2 moieties. Thus, the compound can be a bis-indole. Other compounds of the subject invention can comprise heterocycles such as pyridyl or purine as the A1 and A2 moieties. The core moiety M can be a linear or cyclic group comprising at least three atoms. 0011 Specifically exemplified herein are the novel compounds which have been designated as dragmacidin f, topsentin d, and topsentin e. Advantageously, these compounds have been found to possess anti-neurogenic inflammation activity. 0012 As described herein, the invention also comprises pharmaceutical compositions, e.g. anti-neurogenic inflammatory compositions, containing as an active ingredient an effective amount, of one or more compounds according to the formula expressed above and a non-toxic, pharmaceutically acceptable carrier or diluent. The pharmaceutical compositions of the subject invention can further comprise other active compounds. Such other active compounds include, but are not limited to, anti-inflammatory compounds for example, steroidal compounds, including hydrocortisone and the like; or non-steroidal anti-inflammatories, including acetylsalicylic acid (aspirin), ibuprofen, acetaminophen, indomethacin, and the like. The second active ingredient can include antiviral, antibacterial, antifungal or other antimicrobial compounds or antitumor compounds as well. 0013 As described herein, the invention further comprises processes for the production of compounds and compositions of the invention and novel methods of use thereof, e.g methods of inhibiting a neurogenic inflammatory response in a human or animal. 0014 In accordance with the invention, methods for inhibiting inflammation comprise administering to a human or animal in need of such treatment an effective amount of the pharmaceutical composition

DETAILED DESCRIPTION OF THE INVENTION 0015 The subject invention pertains to novel uses as anti-inflammatory agents of bis-heterocyclic compounds and compositions comprising the bis-heterocyclic compounds.

0037 Skilled chemists having the benefit of the instant disclosure, can readily use procedures to prepare the subject compounds. In carrying out such operations, suitable filtration, chromatographic and other purification techniques can be used. These techniques could include, for example, reversed phase (RPLC), column, vacuum flash, medium pressure (MPLC) and high performance liquid chromatography (HPLC) with a suitable column such as silica gel, Sephadex LH-20, ammonia-treated silica gel, bonded phase RP-18, RP-8 and amino columns. Such columns are eluted with suitable solvents such as heptane, ethyl acetate, methylene chloride, methanol, isopropanol, acetonitrile water, trifluoroacetic acid (TFA) and various combinations thereof. One method of preparation of the compounds used according to the subject invention involves extraction from marine sponges of the genus Spongosorites (Phylum Porifera, Class Demospongiae, Order Halichondrida, Family Halichondriidae). Certain of the samples used in connection with this invention have been assigned to the species Spongosorites ruetzleri (HBOM Catalog Numbers 003:00112, 003:00113, 003:00114, 003:00115, 003:00116, 003:00117, 003:00118, 003:00119, 003:00120, 003:00927); other specimens represent new species of Spongosorites (HBOM Catalog Numbers 003:00549 and 003:00696). For descriptions of these samples and other Spongosorites species, refer to Diaz., M. C., Pomponi, S. A. and Van Soest, R. W. M. (1993) A systematic revision of the central West Atlantic Halichondrida (Demospongiae, Porifera), Part III: Description of valid species, Scientia Marina, 57(4):283-306. All taxonomic voucher samples cited herein with HBOM Catalog Numbers are deposited in the Harbor Branch Oceanographic Museum, Fort Pierce, Fla. All voucher specimens are preserved in 70% ethanol with an expected shelf life of at least 30 years and are accessible to those skilled in the art for taxonomic identification purposes. 0038 A novel use for the described compounds and compositions is their administration to an animal or human as an agent in the control of a neurogenic inflammatory response. Anti-inflammatory activity against cellular activation of specific immune cells, e.g., phorbol myristate acetate (PMA)-induced inflammation, has been described for the subject compounds. See U.S. Pat. Nos. 5,290,777 and 5,464,835, which are hereby incorporated by reference. However, it is well recognized that activity of a compound in inhibiting cellular activated inflammation (e.g., PMA-induced edema or inflammation) is not predictive or suggestive of that compound's activity in inhibiting neurogenic inflammation, e.g., capsaicin-induced or resiniferatoxin (RTX)-induced edema or inflammation. 0039 Therefore, the discovery that the subject compounds have inhibitory activity against neurogenic inflammation is unexpected and advantageous. Neurogenic inflammation is evoked by neuropeptides released from primary afferent nerve terminals and by other secondarily released inflammatory mediators. Specifically, neurogenic inflammation can be evoked by neuropeptides, such as substance P (SP), calcitonin gene-related peptide (CGRP), vasoactive intestinal peptide (VIP), and neurokinin A (NKA), released from primary afferent C-fiber nerve terminals and histamine, secondarily released from mast cells (Dray, A., 1992 Neuro pharmacological mechanisms of capsaicin and related substances Biochem Pharm 44(4):611-15). For purposes of the subject invention, unless otherwise noted, the terms inflammation and inflammatory response refer to any and all such neurogenic inflammatory reactions including, but not limited to, immune-related responses and/or allergic reactions to a physical, chemical, or biological stimulus. Anti-neurogenic inflammatory activity, as used herein, will be understood by those of ordinary skill in the art to mean biological activity inhibiting or controlling a neurogenic inflammatory response. 0040 Anti-inflammatory activity can occur by modes of action which can include, but are not limited to, lipid-mediated inflammatory responses, e.g., (i) suppression of cellular activation of phospholipase A2, either directly (as is known for the anti-inflammatory compound, manoalide) or indirectly (as is known for the anti-inflammatory compound, hydrocortisone); (ii) by inhibiting, or controlling, cyclooxygenation of arachidonic acid, similar to the action of non-steroidal anti-inflammatory drugs; or (iii) by affecting lipooxygenase products of peroxidase reactions to arachidonic acid, or by non-lipid-mediated inflammatory responses, e.g., protease-induced inflammatory responses, and the like. In addition, it is known that capsaicin (CAP), the active constituent found in cayenne pepper, induces an acute neurogenic inflammatory response when applied topically to skin. CAP is a highly selective pain producing substance that selectively stimulates nociceptive and thermal-sensitive nerve endings in tissues by acting on a specific membrane receptor. The mode of action of capsaicin therefore differs significantly from phorbol myristate acetate (PMA)-induced inflammation. By comparison, PMA elicits its pro-inflammatory effects through cellular activation of specific immune cells, such as macrophages and neutrophils. Consequently, the pain response to PMA develops more slowly than the immediate, but transient, pain response to capsaicin. 0041 The compounds and compositions of the subject invention advantageously can block the nociceptive (CAP-induced) inflammatory pathway, thereby providing a method for inhibiting neurogenic inflammation. Accordingly, the compounds can be used in the treatment of inflammation at sites where the primary activating factor is of neurogenic origin, e.g., inflammatory bowel disease or nepehritis. The subject compounds and compositions can be useful in the treatment of chronic pain, migraines, thermal-induced pain, such as sunburn, or other thermal and nociceptive pain, and chronic pain associated with arthritis. Uses can also include other inflammatory conditions that involve a neurogenic pain-producing component, e.g., certain metastic carcinomas or inflammation of the blood vessels. 0042 The compounds of the subject invention can be used to treat a variety of skin conditions including, but not limited to, radiation irritation and burns (including UV and ionizing), chemical bums, rhinitis, thermal burns, reddening of the skin, and chemically indued lesions. 0043 The compounds of the subject invention can also be used to treat allergic response and/or promote wound healing. This can include the use of the compounds in aerosol form for the treatment of acute allergic reactions such as acute asthmatic attack and in the treatment of inflammation of the lung caused by chemical exposure. 0044 The compounds of the subject invention can also be used to treat systemic anaphylactic reactions in animals and man. 0045 The compounds of the subject invention can also be used to treat conjunctivitis and inflammatory gum diseases. 0046 Following are examples which illustrate procedures for practicing the invention. A more complete understanding of the invention can be obtained by reference to the following specific examples of compounds, compositions, and methods of the invention. It will be apparent to those skilled in the art that the examples involve use of materials and reagents that are commercially available from known sources, e.g., chemical supply houses, so no details are given respecting them. These examples should not be construed as limiting. All percentages are by weight and all solvent mixture proportions are by volume unless otherwise noted.

EXAMPLE 3 0069 Inhibition of Resiniferatoxin-Induced Inflammation (Edema) of the Mouse Ear 0070 Induction of mouse ear edema can be conducted by known methods (Inoue, 1-f., N. Nagata, Y. Koshffiara 1993). Compounds to be tested for anti-neurogenic inflammatory activity are topically applied in acetone to the ears of mice in a solution that includes the edema-causing irritant resiniferatoxin (RTX). RTX alone (0.1 g/ear) or in combination with various dilutions of test compound are applied to both sides of the left ears (5 mice per treatment group) and acetone is applied to all right ears. After a 30-minute incubation, the mice are sacrificed, the ears removed, and bores taken and weighed. Edema is measured by subtracting the weight of the right ear (acetone control) from the weight of the left ear (treated). Results are recorded as % decrease (inhibition) or % increase (potentiation) in edema relative to the control group edema. 0071 Bis-heterocycle compounds of the subject invention, e.g., the bis-indole compounds, show significant anti-inflammatory properties. When screened for the ability to reduce edema in mouse ears caused by application of resiniferatoxin (RTX), a known inflammatory agent, a dose of 50 g/ear of topsentin d, (IV), inhibited RTX-induced edema by approximately 96.9%), and a dose of 50 g/ear of topsentin e, (VI), inhibited RTX-induced edema by approximately 88.4%. In the same model, a dose of 50 g/ear of dragmacidin f, (II), inhibited RTX-induced edema by approximately 69.9%.

EXAMPLE 4 0072 Formulation and Administration 0073 The compounds of the invention are useful for various non-therapeutic and therapeutic purposes. It is apparent from the testing that the compounds of the invention are effective for anti-inflammatory uses. 0074 Therapeutic application of the new compounds and compositions containing them can be contemplated to be accomplished by any suitable therapeutic method and technique presently or prospectively known to those skilled in the art. Further the compounds of the invention have use as starting material for intermediates for the preparation of other useful compounds and compositions. 0075 In a preferred embodiment, the compounds or compositions ofthe subject invention are administered in a lotion or other cosmetic preparation. This administration is done directly to the skin where anti-inflammatory activity is desired. 0076 The dosage administration to a host in the above indications will be dependent upon the identity of the infection, the type of host involved, its age, weight, health, kind of concurrent treatment, if any, frequency of treatment and therapeutic ration. 0077 The compounds of the subject invention can be formulated according to known methods for preparing pharmaceutically useful compositions. Formulations are described in detail in a number of sources which are well known and readily available to those skilled in the art. For example, Remington's Pharmaceutical Science by E. W. Martin describes formulations which can be used in connection with the subject invention. In general, the compositions of the subject invention will be formulated such that an effective amount of the bioactive compound(s) is combined with a suitable carrier in order to facilitate effective administration of the composition. 0078 In accordance with the invention, pharmaceutical compositions comprising, as active ingredient, an effective amount of one or more of the subject compounds and one or more non-toxic, pharmaceutically acceptable carriers or diluents can be used by persons of ordinary skill in the art. In addition, the pharmaceutical composition can comprise one or more of the bis-heterocycle compounds, e.g., a bis-indole, as a first active ingredient plus a second active ingredient comprising an anti-inflammatory compound known in the art. Such known anti-inflammatory drugs include, but are not limited to, the steroidal anti-inflammatory drugs and the non-steroidal anti-inflammatory drugs (NSAIDs). 0079 In accordance with this invention, pharmaceutically effective amounts of a known anti-inflammatory agent and the bis-heterocycle compounds are administered sequentially or concurrently to the patient. The most effective mode of administration and dosage regimen of bis-heterocycle compounds and anti-inflammatory agent will depend upon the type of condition to be treated, the severity and course of that condition, previous therapy, the patient's health status, and response to bis-indoles and the judgment of the treating physician. Bis-heterocycle compositions may be administered to the patient at one time or over a series of treatments. 0080 Preferably, the bis-heterocycle, e.g., a bis-indole composition, and any second anti-inflammatory agent are administered sequentially to the patient, with the anti-inflammatory agent being administered before, after, or both before and after treatment with the bis-indole compound. Sequential administration involves treatment with the anti-inflammatory agent at least on the same day (within 24 hours) of treatment with bis-indole and may involve continued treatment with the anti-inflammatory agent on days that the bis-indole is not administered. Conventional modes of administration and standard dosage regimens of anti-inflammatory agents may be used (see Gilman, A. G. et. al. eds The Pharmacological Basis of Therapeutics, pp. 697-713, 1482, 1489-1491 1980; Physicians Desk Reference, 1985 Edition). For example, indomethacin can be administered orally at a dosage of about 25-50 mg, three times a day. Higher doses can also be used. Alternatively, aspirin (about 1500-2000 mg/day), ibuprofen (about 1200-3200 mg/day), or conventional therapeutic doses of other anti-inflammatory agents can be used. Dosages of anti-inflammatory agents can be titrated to the individual patient. 0081 According to one embodiment of this invention, the patient may receive concurrent treatments with the anti-inflammatory agents and compositions comprising bis-heterocycles, e.g. bis-indoles. For example, local intralesional, or intravenous injection of bis-indoles is preferred (see Gilman et. al. supra at pp. 1290-91). The anti-inflammatory agent should preferably be administered by subcutaneous injection, subcutaneous slow release implant, or orally. 0082 Alternatively, the patient can receive a composition comprising a combination of one or more bis-indole compounds and an anti-inflammatory agent according to conventional modes of administration of agents which exhibit antibacterial, anticancer, antitumor or anti-inflammatory activity. These include, for example, parenteral, subcutaneous, intravenous, or intralesional routes of administration. 0083 The compounds used in these therapies can also be in a variety of forms. These include for example, solid, semi-solid and liquid dosage forms, such as tablets, pills, powders, liquid solutions or suspensions, suppositories, injectable and infusible solutions. The preferred form depends on the intended mode of administration and therapeutic application. The compositions also preferably include conventional pharmaceutically acceptable carriers and adjuvants which are known to those of skill in the art. Preferably, the compositions of the invention are in the form of a unit dose and will usually be administered to the patient one or more times a day. 0084 The compounds of the subject invention may also be administered utilizing liposome technology, slow release capsules, implantable pumps, and biodegradable containers. These delivery methods can, advantageously, provide a uniform dosage over an extended period of time. 0085 Examples of such carriers or diluents include ethanol, dimethyl sulfoxide, glycerol, silica, alumina, starch and equivalent carriers and diluents. While effective amounts may vary, as conditions in which compositions are used vary, a minimal dosage required for anti-inflammatory activity is generally between 0.01 and 100 g of the compound. To provide for the administration of such dosages for the desired therapeutic treatment, new pharmaceutical compositions of the invention will advantageously comprise between about 0.1% and 45%, and especially, 1 and 15% by weight of the total of one or more of the new compounds based on the weight of the total composition including carrier or diluent. 0086 Illustratively, dosage levels of the administered active ingredients can be: intravenous, 0.01 to about 20 mg/kg; intraperitoneal, 0.01 to about 100 mg/kg; subcutaneous, 0.01 to about 100 mg/kg; intramuscular, 0.01 to about 100 mg/kg; orally 0.01 to about 200 mg/kg and preferably about 1 to 100 mg/kg; intranasal instillation, 0.01 to about 20 mg/kg; and aerosol, 0.01 to about 20 mg/kg of animal (body) weight. 0087 Once improvement of the patient's condition has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, may be reduced as a function of the symptoms to a level at which the improved condition is retained. When the symptoms have been alleviated to the desired level, treatment should cease. Patients may however require intermittent treatment on a long-term basis upon any recurrence of disease symptoms. 0088 It should be understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and the scope of the appended claims.
