## Abstract

This application is a non-provisional application related to U.S. application Ser. No. 60/103,371, filed on Oct. 7, 1998 priority of which is claimed hereunder.

## Background
This invention relates to compounds and methods for treating prostaglandin mediated diseases, certain pharmaceutical compositions thereof, and the like. More particularly, the compounds of the invention are structurally different from nonsteroidal anti-inflammatory drugs (NSAIDs) and opiates, and are antagonists of the pain and inflammatory effects of E-type prostaglandins.

Two review articles describe the characterization and therapeutic relevance of the prostanoid receptors as well as the most commonly used selective agonists and antagonists: Eicosanoids: From Biotechnology to Therapeutic Applications, Folco, Samuelsson, Maclouf, and Velo eds, Plenum Press, New York, 1996, chap. 14, 137-154 and Journal of Lipid Mediators and Cell Signalling, 1996, 14, 83-87. An article from The British Journal of Pharmacology (1994, 112, 735-740) suggests that Prostaglandin E.sub.2 (PGE.sub.2) exerts allodynia through the EP.sub.1 receptor subtype and hyperalgesia through EP.sub.2 and EP.sub.3 receptors in the mouse spinal cord.

Thus, selective prostaglandin ligands, agonists or antagonists, depending on which prostaglandin E receptor subtype is being considered, will have anti-inflammatory, antipyretic and analgesic properties similar to a conventional non-steroidal anti-inflammatory drug and, in addition, will inhibit hormone-induced uterine contractions and have potential anti-cancer effects, but will have a diminished ability to induce some of the mechanism-based side effects of NSAIDs which are indiscriminate cyclooxygenase inhibitors. In particular, such a compound should have a reduced potential for gastrointestinal toxicity, a reduced potential for renal side effects, a reduced effect on bleeding times and a lessened ability to induce asthma attacks in aspirin-sensitive asthmatic subjects. In The American Physiological Society (1994, 267, R289-R-294), studies suggest that PGE.sub.2 -induced hyperthermia in the rat is mediated predominantly through the EP.sub.1 receptor. World patent applications WO 96/06822 (Mar. 7, 1996), WO 96/11902 (Apr. 25, 1996) and EP 752421-A1 (Jan. 8, 1997) disclose compounds represented by Formula I as being useful in the treatment of prostaglandin mediated diseases. ##STR2##

For example, a formulation intended for the oral administration of humans may contain from 0.5 mg to 5 g of active agent compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Dosage unit forms will generally contain between from about 1 mg to about 2 g of an active ingredient, typically 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, 400 mg, 500 mg, 600 mg, 800 mg, or 1000 mg.

Pharmaceutical Compositions

For the treatment of any of the prostanoid mediated diseases compound II may be administered orally, topically, parenterally, by inhalation spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes subcutaneous injections, intravenous, intramuscular, intrasternal injection or infusion techniques. In addition to the treatment of warm-blooded animals such as mice, rats, horses, cattle, sheep, dogs, cats, etc., the compound of the invention is effective in the treatment of humans.

The pharmaceutical compositions containing the active ingredient may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for the manufacture of tablets. These excipients may be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example, magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate may be employed. They may also be coated by the technique described in the U.S. Pat. No. 4,256,108; 4,166,452; and 4,265,874 to form osmotic therapeutic tablets for control release.

Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredients is mixed with water-miscible solvents such as propylene glycol, PEGs and ethanol, or an oil medium, for example peanut oil, liquid paraffin, or olive oil.

Aqueous suspensions contain the active material in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl, p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose, saccharin or aspartame.

Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example arachis oil, olive oil, sesame oil or coconut oil, or in mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring and coloring agents, may also be present.

The pharmaceutical compositions of the invention may also be in the form of an oil-in-water emulsion. The oily phase may be a vegetable oil, for example olive oil or arachis oil, or a mineral oil, for example liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring agents.

Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents. The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleagenous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1,3-butane diol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. Cosolvents such as ethanol, propylene glycol or polyethylene glycols may also be used. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

Compound II may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient which is solid at ambient temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are cocoa butter and polyethylene glycols. For topical use, creams, ointments, gels, solutions or suspensions, etc., containing the compound of Formula II are employed. (For purposes of this application, topical application shall include mouth washes and gargles.) Topical formulations may generally be comprised of a pharmaceutical carrier, cosolvent, emulsifier, penetration enhancer, preservative system, and emollient.

Utilities

The ability of the compounds of Formula II (i.e., Compound II) to interact with prostaglandin receptors makes them useful for preventing or reversing undesirable symptoms caused by prostaglandins in a mammalian, especially human subject. This mimicking or antagonism of the actions of prostaglandins indicates that the compounds and pharmaceutical compositions thereof are useful to treat, prevent, or ameliorate in mammals and especially in humans: Pain, fever and inflammation of a variety of conditions including rheumatic fever, symptoms associated with influenza or other viral infections, common cold, low back and neck pain, skeletal pain, post-partum pain, dysmenorrhea, headache, migraine, toothache, sprains and strains, myositis, neuralgia, synovitis, arthritis, including rheumatoid arthritis, degenerative joint diseases (osteoarthritis), gout and ankylosing spondylitis, bursitis, burns including radiation and corrosive chemical injuries, sunburns, pain following surgical and dental procedures as well as immune and autoimmune diseases. In addition, such a compound may inhibit cellular neoplastic transformations and metastic tumor growth and hence can be used in the treatment of cancer. Compound II may also be of use in the treatment and/or prevention prostaglandin-mediated proliferation disorders such as may occur in diabetic retinopathy and tumor angiogenesis. Compound II will also inhibit prostanoid-induced smooth muscle contraction by antagonizing contractile prostanoids or mimicking relaxing prostanoids and hence may be use in the treatment of dysmenorrhea, premature labor, asthma and eosinophil related disorders. It will also be of use in the treatment of Alzheimer's disease, the treatment of glaucoma, for the prevention of bone loss (treatment of osteoporosis) and for the promotion of bone formation (treatment of fractures) and other bone diseases such as Paget's disease.

By virtue of its prostanoid or prostanoid antagonist activity, Compound II will prove useful as an alternative to conventional non-steroidal anti-inflammatory drugs (NSAID'S) particularly where such non-steroidal anti-inflammatory drugs may be contraindicated such as in patients with peptic ulcers, gastritis, regional enteritis, ulcerative colitis, diverticulitis or with a recurrent history of gastrointestinal lesions; GI bleeding, coagulation disorders including anemia such as hypoprothrombinemia, haemophilia or other bleeding problems; kidney disease; thrombosis, occlusive vascular diseases; those prior to surgery or taking anti-coagulants. Compound II will also be useful as a cytoprotective agent for patients under chemotherapy. In addition, compounds of Formula II may be combined with conventional nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, ketoprofen, and naproxen.

Similarly, compounds of Formula II, will be useful as a partial or complete substitute for conventional NSAIDs in preparations wherein they are presently co-administered with other agents or ingredients. Thus in further aspects, the invention encompasses pharmaceutical compositions for treating prostaglandin mediated diseases as defined above comprising the compound of Formula II as defined above and one or more ingredients such as another pain reliever including acetominophen or phenacetin; a potentiator including caffeine; an H2-antagonist; aluminum or magnesium hydroxide; simethicone; a decongestant including phenylephrine, phenylpropanolamine, pseudophedrine, oxymetazoline, ephinephrine, naphazoline, xylometazoline, propylhexedrine, or levo-desoxyephedrine; an antiitussive including codeine, hydrocodone, caramiphen, carbetapentane, or dextramethorphan; a diuretic; a sedating or non-sedating antihistamine; a cyclooxygenase-2 (COX-2) inhibitor. Examples of such COX-2 inhibitors are disclosed in U.S. Pat. Nos. 5,474,995; 5,633,272; and 5,466,823; and in WO 96/25405, WO 97/38986, WO 98/03484, WO 97/14691, and WO 95/0051.

Preparation of Intermediates

Biphenyl Sulfonamides:

As shown in Scheme I, 2-bromobenzenesulfonyl chloride III (purchased from Lancaster) is reacted withtert-butylamine. The resulting sulfonamide IV is converted, via a palladium-catalyzed coupling with boronic acid V (purchased from Omega Chemical Company Inc.) to biphenyl derivative VI. When treated with HBr in acetic acid, activation of the hydroxyl group and deprotection occur in the same procedure to afford sulfonamide VII. This sulfonamide is a common intermediate used in alkylation reactions with azocinones (dibenzolactams). ##STR4##

Substituted boronic acids can also be prepared according to the following scheme: ##STR5##

Synthesis of Compounds

Azocinones (dibenzolactams):

Tetrahydrodibenz[b,f]azocin-6-one (VIII), shown in Scheme 2, is commercially available from Aldrich Chemical Co., Inc., in Milwaukee, Wis. The corresponding unsaturated compound IX can be prepared (VIII can also be prepared in the same manner from dibenzosuberone) from commercially available dibenzosuberenone (X) via a two-step sequence (i-oxime formation using hydroxylamine and ii-Beckmann rearrangement on the corresponding tosylate) as shown in Scheme 2. ##STR6##

As depicted in Scheme 3, other dibenzolactam and heteroarylenediyl derivatives can be prepared via a three-step sequence: (I) palladium-catalyzed Heck reaction; (ii) hydrogenation and (iii) cyclization induced by 1-hydroxybenzotriazole hydrate (HOBT), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDCl) and potassium hydride. For example, fluorinated derivatives XI and XII are prepared from the reaction of styryl derivative XV and anilines XIII and XIV, respectively (both purchased from Lancaster). Heteroaryl starting materials related to XV can also be prepared using the Heck reaction on the corresponding heteroaryl bromide and ethylene. ##STR7##

Alternatively, compound VIII can be converted to VIIIA and subsequently to VIIIB via a benzylic bromination reaction using N-bromosuccinimide (NBS) outlined in Scheme 4 and described in J. Org. Chem. 1972, p. 4907. This intermediate can in turn be transformed to VIIIC using standard procedures and VIIIE can be obtained from VIIIC following one of many protocol for carbonyl transposition (PhCHO,OH-/LiAlH.sub.4, AlCl.sub.3 /O.sub.3). These isomers can then each be transformed to the difluoro analog VIIID and VIIIF by reaction with DAST (diethylaminosulfur trifluoride). The lactams corresponding to products VIIID and VIIIF can then be obtained using standard hydrolytic procedures. Other lactams described herein can be prepared according to published procedures and/or are commercially available. ##STR8##

As shown in Scheme 5, dibenzolactam VIII was then treated with sodium hydride and sulfonamide VII to provide biphenyl derivative XVI which serves as a common intermediate for the synthesis of several of the compounds of the present invention. Alternatively, dibenzolactam VIII can be replaced by any of the lactams IX, XI or XII and reacted with VII. Compound XVI can then be transformed to several compounds depending on the choice of the acid chlorides used. For example, treatment of XVI with hydrocinnamoyl chloride and Hunig's base in DMF (dimethylformamide) provides acid sulfonamide XVII. ##STR9##

Preparation of Intermediates

2-bromo tert-butylbenzenesulfonamide IV ##STR10##

At 0.degree. C., carbon tetrabromide (12.5 g, 37.6 mmol) was added to compound VI (10 g, 31.3 mmol) in dichloromethane (100 mL). Bis(diphenylphosphino)ethane (7.5 g, 0.6 mmol) was then added portionwise. The mixture was stirred at 0.degree. C. for 12 hours and it was then poured into dry ether (750 mL), filtered over Celite and evaporated. Trifluoroacetic acid (100 mL) was then added and the resulting mixture was evaporated under reduced pressure. The residue was recrystallized from hexanes.

Assays For Determining Biological Activity

The compound of Formula II can be tested using the following assays to determine their prostanoid antagonist or agonist activity in vitro and in vivo and their selectivity. The prostaglandin receptors investigated were DP, EP.sub.1, EP.sub.2, EP.sub.3, EP.sub.4, FP, IP and TP.

Stable Expression of Prostanoid Receptors in the Human Embryonic Kidney (HEK) 293(ebna) Cell Line

Prostanoid receptor cDNAs corresponding to full length coding sequences were subcloned into the appropriate sites of mammalian expression vectors and transfected into HEK 293(ebna) cells. HEK 293(ebna) cells expressing the individual cDNAs were grown under selection and individual colonies were isolated after 2-3 weeks of growth using the cloning ring method and subsequently expanded into clonal cell lines.

Prostanoid Receptor Binding Assays

HEK 293(ebna) cells are maintained in culture, harvested and membranes are prepared by differential centrifugation, following lysis of the cells in the presence of protease inhibitors, for use in receptor binding assays. Prostanoid receptor binding assays are performed in 10 mM MES/KOH (pH 6.0) (EPs, FP and TP) or 10 mM HEPES/KOH (pH 7.4) (DP and IP), containing 1 mM EDTA, 10 mM divalent cation and the appropriate radioligand. The reaction is initiated by addition of membrane protein. Ligands are added in dimethylsulfoxide which is kept constant at 1% (v/v) in all incubations. Non-specific binding is determined in the presence of 1 .mu.M of the corresponding non-radioactive prostanoid. Incubations are conducted for 60 min at room temperature or 30.degree. C. and terminated by rapid filtration. Specific binding is calculated by subtracting non specific binding from total binding. The residual specific binding at each ligand concentration is calculated and expressed as a function of ligand concentration in order to construct sigmoidal concentration-response curves for determination of ligand affinity.

Prostanoid Receptor Agonist and Antagonist Assays

Whole cell second messenger assays measuring stimulation (EP.sub.2, EP.sub.4, DP and IP in HEK 293(ebna) cells) or inhibition (EP.sub.3 in human erythroleukemia (HEL) cells) of intracellular cAMP accumulation or mobilization of intracellular calcium (EP.sub.1, FP and TP in HEK 293(ebna) cells stably transfected with apo-aequorin) are performed to determine whether receptor ligands are agonists or antagonists. For cAMP assays, cells are harvested and resuspended in HBSS containing 25 mM HEPES, pH 7.4. Incubations contain 100 .mu.M RO-20174 (phosphodiesterase type IV inhibitor, available from Biomol) and, in the case of the EP.sub.3 inhibition assay only, 15 .mu.M forskolin to stimulate cAMP production. Samples are incubated at 37.degree. C. for 10 min, the reaction is terminated and cAMP levels are then measured. For calcium mobilization assays, cells are charged with the co-factors reduced glutathione and coelenterazine, harvested and resuspended in Ham's F12 medium. Calcium mobilization is measured by monitoring luminescence provoked by calcium binding to the intracellular photoprotein aequorin. Ligands are added in dimethylsulfoxide which is kept constant at 1% (v/v) in all incubations. For agonists, second messenger responses are expressed as a function of ligand concentration and both EC.sub.50 values and the maximum response as compared to a prostanoid standard are calculated. For antagonists, the ability of a ligand to inhibit an agonist response is determined by Schild analysis and both KB and slope values are calculated.

The method is the same as described in Chan et al. (J. Pharmacol. Exp. Ther. 274: 1531-1537, 1995).

LPS-Induced Pyrexia in Conscious Squirrel Monkeys

The method is the same as described in Chan et al. (Eur. J. Pharmacol. 327: 221-225, 1997).

Acute Inflammatory Hyperalgesia Induced by Carrageenan in Rats

The method is the same as described in Boyce et al. (Neuropharmacology 33: 1609-1611, 1994).

Adiuvant-Induced Arthritis in Rats

Female Lewis rats (body weight .about.146-170 g) were weighed, ear marked, and assigned to groups (a negative control group in which arthritis was not induced, a vehicle control group, a positive control group administered indomethacin at a total daily dose of 1 mg/kg and four groups administered with a test compound at total daily doses of 0.10-3.0 mg/kg) such that the body weights were equivalent within each group. Six groups of 10 rats each were injected into a hind paw with 0.5 mg of Mycobacterium butyricum in 0.1 mL of light mineral oil (adjuvant), and a negative control group of 10 rats was not injected with adjuvant. Body weights, contralateral paw volumes (determined by mercury displacement plethysmography) and lateral radiographs (obtained under Ketamine and Xylazine anesthesia) were determined before (day -1) and 21 days following adjuvant injection, and primary paw volumes were determined before (day -1) and on days 4 and 21 following adjuvant injection. The rats were anesthetized with an intramuscular injection of 0.03-0.1 mL of a combination of Ketamine (87 mg/kg) and Xylazine (13 mg/kg) for radiographs and injection of adjuvant. The radiographs were made of both hind paws on day 0 and day 21 using the Faxitron (45 kVp, 30 seconds) and Kodak X-OMAT TL film, and were developed in an automatic processor. Radiographs were evaluated for changes in the soft and hard tissues by an investigator who was blinded to experimental treatment. The following radiographic changes were graded numerically according to severity: increased soft issue volume (0-4), narrowing or widening of joint spaces (0-5) subehondral erosion (0-3), periosteal reaction (0-4), osteolysis (0-4) subluxation (0-3), and degenerative joint changes (0-3). Specific criteria were used to establish the numerical grade of severity for each radiographic change. The maximum possible score per foot was 26. A test compound at total daily doses of 0.1, 0.3, 1, and 3 mg/kg/day, indomethacin at a total daily dose of 1 mg/kg/day, or vehicle (0.5% methocel in sterile water) were administered per os b.i.d. beginning post injection of adjuvant and continuing for 21 days. The compounds were prepared weekly, refrigerated in the dark until used, and vortex mixed immediately prior to administration.
