Description: SUBSTITUTED TRICYCLICS FIELD OF THE INVENTION This invention relates to novel substituted tricyclic organic compounds useful for inhibiting sPLA2 mediated release of fatty acids for the treatment of inflammatory diseases. BACKGROUND INFORMATION The structure and physical properties of human non- pancreatic secretory phospholipase A2 (hereinafter called, "SPLA2") has-been thoroughly described in two articles, namely, "Cloning and Recombinant Expression of Phospholipase A2 Present in Rheumatoid Arthritic Synovial Fluid" by Seilhamer, Jeffrey J. ; Pruzanski, Waldemar; Vadas Peter; Plant, Shelley; Miller, Judy A. ; Kloss, Jean; and Johnson, Lorin K. ; The Journal of Biological Chemistry, Vol. 264, No. 10, Issue of April 5, pp. 5335- 5338, 1989; and "Structure and Properties of a Human Non- pancreatic Phospholipase A2" by Kramer, Ruth M. ; Hession, Catherine; Johansen, Berit; Hayes, Gretchen; McGray, Paula; Chow, E.

It is believed that SP A2 is a rate limiting enzyme in the arachidonic acid cascade which hydrolyzes membrane phospholipids . Thus, it is important to develop compounds that inhibit sPLA2 mediated release of fatty acids (e.g., arachidonic acid). Such compounds would be of value in the general treatment of conditions induced and/or maintained by overproduction of sPLA2 such as septic shock, adult respiratory distress syndrome, pancreatitis, trauma-induced shock, bronchial asthma, allergic rhinitis, rheumatoid arthritis, etc. It is desirable to develop new compounds and treatments for SPLA2 induced diseases.

Representative pharmaceutically acceptable salts include but are not limited to the alkali and alkaline earth salts such as lithium, sodium, potassium, calcium, magnesium, aluminum and the like. Salts are conveniently prepared from the free acid by treating the acid in solution with a base or by exposing the acid to an ion exchange resin. Included within the definition of pharmaceutically acceptable salts are the relatively non-toxic, inorganic and organic base addition salts of compounds of the present invention, for example, ammonium, quaternary ammonium, and amine cations, derived from nitrogenous bases of sufficient basicity to form salts with the compounds of this invention (see, for example, S. M. Berge, et al . , "Pharmaceutical Salts," J. Phar . Sci . , 66: 1-19 (1977)). Compounds of the invention may have chiral centers and exist in optically active forms.

Prodrugs are derivatives of the compounds of the invention which have chemically or metabolically cleavable groups and become by solvolysis or under physiological conditions the compounds of the invention which are pharmaceutically active in vivo . Derivatives of the compounds of this invention have activity in both their acid and base derivative forms, but the acid derivative form often offers advantages of solubility, tissue compatibility, or delayed release in a mammalian organism (see, Bundgard, H. , Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives, such as, esters prepared by reaction of the parent acidic compound with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a suitable amine. Simple aliphatic esters (e.g., methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, tert-butyl) or aromatic esters derived from acidic groups pendent on the compounds of, this invention are preferred prodrugs. Other preferred esters include morpholinoethyloxy, diethylglycolamide and diethylaminocarbonylmethoxy. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy) alkyl esters or ( (alkoxycarbonyl) oxy) alkyl esters . The term "acid protecting group" is used herein as it is frequently used in synthetic organic chemistry, to refer to a group which will prevent an acid group from participating in a reaction carried out on some other functional group in the molecule, but which can be removed when it is desired to do so. Such groups are discussed by T. W. Greene in chapter 5 of Protective Groups in Organic Synthesis, John Wiley and Sons, New York, 1981, incorporated herein by reference in its entirety.

An appropriately substituted nitrobenzene (1) can be reduced to the aniline (2) by treatment with a reducing agent, such as hydrogen in the presence of Pd/C, preferably at room temperature . Compound (2) is N-alkylated at temperatures of from about 0 to 20 °C using an alkylating agent such as an appropriately substituted aldehyde and sodium cyanoborohydride to form (3). Alternately, an appropriately substituted benzyl halide may be used for the first alkylation step. The resulting intermediate is further N-alkylated by treatment with 2-carbethoxy-6- bromocyclohexanone, preferably at temperatures of about 80 °C to yield (4) or by treatment with potassium hexamethyldisilazide and the bromoketoester . The product (4) is cyclized to the tetrahydrocarbazole (5) by refluxing with ZnCl2 in benzene for from about 1 to 2 days, preferably at 80 °C, (See Julia, M. ; Lenzi, J. Preparation d'acides tetrahydro-1, 2, 3, 4-carbazole-l ou -4. Bull . Soc . Chim. France, 1962, 2262-2263). Compound (5) is converted to the hydrazide (6) by treatment with hydrazine at temperatures of about 100 °C, or to the amide (7) by reacting with methylchloroaluminum amide in benzene (see Levin, J.I.; Turos, E.; Weinreb, S.M. An alternative procedure for the aluminum-mediated conversion of esters to amides. Syn . Comm. , 1982, 12, 989-993) . Alternatively, (7) may be produced by treatment of (6) with Raney nickel active catalyst. It will be readily appreciated that when R 3 ( a ) j_ S: alkyl), conversion to the amide will also be achieved in this procedure. Compounds (6) and (7) may be dealkylated, preferably at 0°C to room temperature, with a dealkylating agent, such as boron tribromide or sodium thioethoxide, to give compound (7) where R^ (a) ± s _OH, which may then be further converted to compound (9), by realkylating with a base, such as sodium hydride, and an alkylating agent, such as Br(CH2) m R^, where R^ is the carboxylate or phosphonic diester or nitrile as defined above. Conversion of R^ to the carboxylic acid may be accomplished by treatment with an aqueous base. When R2 is nitrile, conversion to the tetrazole may be achieved by reacting with tri-butyl tin azide or conversion to the carboxamide may be achieved by reacting with basic hydrogen peroxide. When R^ is the phosphonic diester, conversion to the acid may be achieved by reacting with a dealkylating agent such as tri ethylsilyl bromide. The onoester may be accomplished by reacting the diester with an aqueous base. When R2 and R 3 are both methoxy, selective demethylation can be achieved by treating with sodium ethanethiolate in dimethylformamide at 100 °C. An alternative synthesis of intermediate (5) is shown in Scheme 1(b), as follows. Scheme Ig(b) (2) where PG is a protecting group; R 3a is as defined in Scheme 1, above. The aniline (2) is N-alkylated with 2-carbethoxy-6- bro ocyclohexanone in dimethyl formamide in the presence of sodium bicarbonate for 8-24 hours at 50 °C . Preferred protecting groups include methyl, carbonate, and silyl groups, such as t-butyldimethylsilyl . The reaction product (4') is cyclized to (5') using the ZnCl2 i- n benzene conditions described in Scheme 1(a), above. N- alkylation of (5') to yield (5) is accomplished by treatment with sodium hydride and the appropriate alkyl halide in dimethylformamide at room temperature for 4-8 hours . Scheme Ilg R 3 ( a ) i s as defined in Scheme Ig, As discussed in Scheme I above, carbazole (5) is hydrolyzed to the carboxylic acid (10) by treatment with an aqueous base, preferably at room temperature to about 100 °C. The intermediate is then converted to an acid chloride utilizing, for example, oxalyl chloride and dimethylformamide, and then further reacted with a lithium salt of (S) or (R) -4-alkyl-2-oxazolidine at a temperature of about -75 °C, to give (11a) and (lib) , which are separable by chromatography. The diastereomers are converted to the corresponding enantiomeric benzyl esters (12) by brief treatment at temperatures of about 0 °C to room temperature with lithium benzyl oxide. See Evans, D.A.; Ennis, M.D. ,- Mathre, D.J. Asymmetric alkylation reactions of chiral imide enolates . A practical approach to the enantioselective synthesis of alpha-substituted carboxylic acid derivatives. J.Ara. Chem. Soc . , 1982, 104 , 1737-1738. The esters (12) are then converted to (7) preferably by treatment with methylchloroaluminum amide (see Levin, J.I.; Turos, E.,- Weinreb, S.M. An alternative procedure for the aluminum-medi ted conversion of esters to amides is disclosed in Syn . Comm. , 1982, 12, 989-993. Alternately, the conversion of esters to amides may be accomplished by hydrogenation using, for example, hydrogen and palladium on carbon, as described above, to make the acid and then reacting with an acyl azide, such as diphenylphosphoryl azide followed by treatment with ammonia. Using the procedure described above in Scheme I, preparation of compound (9a) or (9b) may be accomplished. Compounds of formula Ie where Z is phenyl can be prepared as follows in Schemes III(a)-(f), below. Scheme III (a) (13) (14) A 1,2,3, 4-tetrahydrocarbazole-4-carboxamide or 4- carboxhydrazide (13) is dehydrogenated by refluxing in a solvent such as carbitol in the presence of Pd/C to produce the carbazole-4-carboxamide. Alternately, treatment of (13) with DDQ in an appropriate solvent such as dioxane yields carbazole (14) . Depending on the substitution pattern, oxidation as described above may result in de-alkylation of the nitrogen. For example when R 3 is substituted at the 8- position with methyl, oxidation results in dealkylation of the nitrogen which may be realkylated by treatment with sodium hydride and the appropriate alkyl halide as described in Scheme 1(a) above to prepare the desired product (14) .

In addition, U.S. Patent No. 4,885,338 and Jpn. Kokai Tokkyo Koho 05286912, Nov 1993 Hesei teach a method for • preparing 2-fluoro-5-methoxyaniline derivatives useful for the preparation of a starting material for the purpose of the present invention. Scheme IΙIg (c ) 1 22 ) ( 23 ) ( 24 ) R is as defined in Scheme IΙIg(b), R3 ( a ) £ s as defined in Scheme Ig(a), above; and X is halo. Benzoic acid derivatives (16) (X= CI, Br, or I) and boronic acid derivative (27) (either commercially available or readily prepared by known techniques from commercially available starting materials) are condensed under the general procedure of Miyaura, et al . , N. Miyaura, et al . , Synth. Commun. 11, 513 (1981) or Trecourt, et al . , F. Trecourt, et al . , Tetrahedron, 51, 11743 6) in the presence of a palladium catalyst, such as Pd(P.3P)4, a base, such as sodium bicarbonate, in an inert solvent, such as THF, toluene or ethanol, to afford compound (28) . Compound (28) is converted to the carbazole product (29) by treatment with a trialkyl or triaryl phosphite or phosphine, such as, triethylphosphite or triphenyl phosphine, according to the general procedure of Cadogan, et al . (see J. Cadogan et al . , J. Chem. Soc . , 4831 (1965) Compound (29) is N-alkylated with an appropriately substituted alkyl or aryl halide XCH R in the presence of a base, such as sodium hydride or potassium carbonate, in a non-interfering solvent, such as toluene, dimethylformamide, or dimethylsulfoxide to afford carbazole (30) .

When R (a ) is substituted at the 8-position with chloro, de-alkylation of (30) with boron tribromide results in de-benzylation of the nitrogen as described above. Alkylation may be readily accomplished in a two step process. First, an O-alkylation by treatment with a haloalkyl acetate such as methyl bro o acetate using sodium hydride in tetrahydrofuran, followed by N- alkylation using for example a base such as sodium hydride and an appropriately substituted alkyl or aryl halide in dimethoxy formamide.

Therapeutic Use of Tricyclic Compounds The compounds described herein are believed to achieve their beneficial therapeutic action principally by direct inhibition of human SPLA2 , and not by acting as antagonists for arachidonic acid, nor other active agents below arachidonic acid in the arachidonic acid cascade, such as 5-lipoxygenases, cyclooxygenases, etc. The method of the invention for inhibiting SPLA2 mediated release of fatty acids comprises contacting sPLA with a therapeutically effective amount of the compound of Formula (I) or its salt. The compounds of the invention may be used in a method of treating a mammal (e.g., a human) to alleviate the pathological effects of septic shock, adult respiratory distress syndrome, pancreatitus, trauma, bronchial asthma, allergic rhinitis, and rheumatoid arthritis; wherein the method comprises administering to the mammal a compound of formula (I) in a therapeutically effective amount. A "therapeutically effective" amount is an amount sufficient to inhibit sPLA2 mediated release of fatty acid and to thereby inhibit or prevent the arachidonic acid cascade and its deleterious products. The therapeutic amount of compound of the invention needed to inhibit SP A2 may be readily determined by taking a sample of body fluid and assaying it for sPLA 2 content by conventional methods . Throughout this document, the person or animal to be treated will be described as a "mammal", and it will be understood that the most preferred subject is a human. Use of the present compounds in non-human animals is also a contemplated aspect of the invention. It will be understood that the dosage ranges for other animals will necessarily be quite different from the doses administered to humans, and accordingly that the dosage ranges described will be recalculated. For example, a small dog may be only l/10 th of a typical human's size, and it will therefore be necessary for a much smaller dose to be used. The determination of an effective amount for a certain non- human animal is carried out in the same manner described below in the case of humans, and veterinarians are well accustomed to such determinations . Pharmaceutical Formulations of the Invention As previously noted the compounds of this invention are useful for inhibiting SPLA2 mediated release of fatty acids such as arachidonic acid. By the term, "inhibiting" is meant the prevention or therapeutically significant reduction in release of sPLA2 initiated fatty acids by the compounds of the invention. By "pharmaceutically acceptable" it is meant the carrier, diluent or excipient must be compatible with the other ingredients of the formulation and not deleterious to the recipient thereof . In general, the compounds of the invention are most desirably administered at a dose that will generally afford effective results without causing any serious side effects and can be administered either as a single unit dose, or if desired, the dosage may be divided into convenient subunits administered at suitable times throughout the day. The specific dose of a compound administered according to this invention to obtain therapeutic or prophylactic effects will, of course, be determined by the particular circumstances surrounding the case, including, for example, the route of administration, the age, weight and response of the individual patient, the condition being treated and the severity of the patient's symptoms. Typical daily doses will contain a non-toxic dosage level of from about 0.01 mg/kg to about 50 mg/kg of body weight of an active compound of this invention. Preferably the pharmaceutical formulation is in unit dosage form. The unit dosage form can be a capsule or tablet itself, or the appropriate number of any of these. The quantity of active ingredient in a unit dose of composition may be varied or adjusted from about 0.1 to about 1000 milligrams or more according to the particular treatment involved. It may be appreciated that it may be necessary to make routine variations to the dosage depending on the age and condition of the patient. The dosage will also depend on the route of administration. A "chronic" condition means a deteriorating condition of slow progress and long continuance. As such, it is treated when it is diagnosed and continued throughout the course of the disease. An "acute" condition is an exacerbation of short course followed by a period of remission. In an acute event, compound is administered at the onset of symptoms and discontinued when the symptoms disappear. Pancreatitis, trauma-induced shock, bronchial asthma, allergic rhinitis and rheumatoid arthritis may occur as an acute event or a chronic event. Thus, the treatment of these conditions contemplates both acute and chronic forms. Septic shock and adult respiratory distress, on the other hand, are acute conditions treated when diagnosed. The compound can be administered by a variety of routes including oral, aerosol, rectal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal . Pharmaceutical formulations of the invention are prepared by combining (e.g., mixing) a therapeutically effective amount of the compounds of the invention together with a pharmaceutically acceptable carrier or diluent therefor. The present pharmaceutical formulations are prepared by known procedures using well known and readily available ingredients . In making the compositions of the present invention, the active ingredient will usually be admixed with a carrier, or diluted by a carrier, or enclosed within a carrier which may be in the form of a capsule, sachet, paper or other container. When the carrier serves as a diluent, it may be a solid, semi- solid or liquid material which acts as a vehicle, or can be in the form of tablets, pills, powders, lozenges, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium) , or ointment, containing, for example, up to 10% by weight of the active compound. The compounds of the present invention are preferably formulated prior to administration. For the pharmaceutical formulations any suitable carrier known in the art can be used. In such a formulation, the carrier may be a solid, liquid, or mixture of a solid and a liquid. Solid form > formulations include powders, tablets and capsules. A solid carrier can be one or more substances which may also act as flavoring agents, lubricants, solubilisers, suspending agents, binders, tablet disintegrating agents and encapsulating material . Tablets for oral administration may contain suitable excipients such as calcium carbonate, sodium carbonate, lactose, calcium phosphate, together with disintegrating agents, such as maize, starch, or alginic acid, and/or binding agents, for example, gelatin or acacia, and lubricating agents such as magnesium stearate, stearic acid, or talc. In powders the carrier is a finely divided solid which is in admixture with the finely divided active ingredient. In tablets the active ingredient is mixed with a carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from about 1 to about 99 weight percent of the active ingredient which is the novel compound of this invention. Suitable solid carriers are magnesium carbonate, magnesium stearate, talc, sugar lactose, pectin, dextrin, starch, gelatin, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, low melting waxes, and cocoa butter. Sterile liquid form formulations include suspensions, emulsions, syrups and elixirs. The active ingredient can be dissolved or suspended in a pharmaceutically acceptable carrier, such as sterile water, sterile organic solvent or a mixture of both. The active ingredient can often be dissolved in a suitable organic solvent, for instance aqueous propylene glycol. Other compositions can be made by dispersing the finely divided active ingredient in aqueous starch or sodium carboxymethyl cellulose solution or in a suitable oil. The following pharmaceutical formulations 1 through 8 are illustrative only and are not intended to limit the scope of the invention in any way. "Active ingredient", refers to a compound according to Formula (I) , (II) or (III) or a pharmaceutically acceptable salt, solvate, or prodrug thereof.

Assay Experiments Assay Example 1 The following chromogenic assay procedure was used to identify and evaluate inhibitors of recombinant human secreted phospholipase A2. The assay described herein has been adapted for high volume screening using 96 well microtiter plates. A general description of this assay method is found in the article, "Analysis of Human Synovial Fluid Phospholipase A2 on Short Chain Phosphatidylcholine-Mixed Micelles : Development of a Spectrophotometric Assay Suitable for a Microtiterplate Reader", by Laure J. Reynolds, Lori L. Hughes, and Edward A Dennis, Analytical Biochemistry, 204, pp. 190- 197, 1992 (the disclosure of which is incorporated herein by reference) : Reagents : REACTION BUFFER - CaCl2-2H2θ (1.47 g/L) KC1 (7.455 g/L) Bovine ■ Serum Albumin (fatty acid free) (1 g/L) (Sigma A-7030, product of Sigma Chemical Co.

Meridian Road, Rockford, Illinois 61101 . REACTION MIXTURE - A measured volume of racemic dipheptanoyl thio PC supplied in chloroform at a concentration of 100 mg/ml is taken to dryness and redissolved in 10 millimolar TRITON X-100™ nonionic detergent aqueous solution. Reaction Buffer is added to the solution, then DTNB to give the Reaction Mixture . The reaction mixture thus obtained contains ImM diheptanoly thio-PC substrate, 0.29 mm Triton X- 100™ detergent, and 0.12 mm DTMB in a buffered aqueous solution at pH 7.5. Assay Procedure: 1. Add 0.2 ml reaction mixture to all wells; 2. Add 10 ul test compound (or solvent blank) to appropriate wells, mix 20 seconds; 3. Add 50 nanograms of SPLA2 (10 microliters) to appropriate wells; 4. Incubate plate at 40°C for 30 minutes; 5. Read absorbance of wells at 405 nanometers with an automatic plate reader. All compounds were tested in triplicate. Typically, compounds were tested at a final concentration of 5 ug/ml . Compounds were considered active when they exhibited 40% inhibition or greater compared to uninhibited control reactions when measured at 405 nanometers. Lack of color development at 405 nanometers evidenced inhibition. Compounds initially found to be active were reassayed to confirm their activity and, if sufficiently active, IC50 values were determined. Typically, the IC50 values (see, Table I, below) were determined by diluting test compound serially two-fold such that the final concentration in the reaction ranged from 45 ug/mL to 0.35 ug/ml . More potent inhibitors required significantly greater dilution. In all cases, % inhibition measured at 405 nanometers generated by enzyme reactions containing inhibitors relative to the uninhibited control reactions was determined. Each sample was titrated in triplicate and result values were averaged for plotting and calculation of IC50 values. IC50 were determined by plotting log concentration versus inhibition values in the range from 10-90% inhibition. Compounds of the instant invention were tested in Assay Example 1 and were found to be effective at concentrations of less than lOOμM.
