BACKGROUND INFORMATION The structure and physical properties of human non- pancreatic secretory phospholipase A2 (hereinafter called, MPLA2") has been thoroughly described in two articles, namely, "Cloning and Recombinant Expression of Phospholipase 2 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 2" by Kramer, Ruth M.; Hession, Catherine; Johansen, Berit; Hayes, Gretchen; McGray, Paula; Chow, E.

Blake; The Journal of Biological Chemistry, Vol. 264, No. 10, Issue of April 5, pp. 5768-5775, 1989; the disclosures of which are incorporated herein by reference . It is believed that sPLA2 is a rate limiting enzyme in the arachidonic acid cascade which hydrolyzes membrane phospholipids . Thus, it is important to develop compounds which inhibit sPLA2 mediated release of fatty acids (e.g., arachidonic acid). Such compounds would be of value in 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.

The words, "acid linker length", refer to the number of atoms (excluding hydrogen) in the shortest chain of the linking group -(L a )- that connects the 7 or 8 position of the tricyclic nucleus with the remainder of the chain. The presence of a carbocyclic ring in -(L a )- counts as the number of atoms approximately equivalent to the calculated diameter of the carbocyclic ring. Thus, a benzene or cyclohexane ring in the acid linker counts as 2 atoms in calculating the length of -(L a )~. Illustrative acid linker groups are; where t is 1 to 5, Q is selected from the group -(CH2! -0-, -NH-, and -S-, and R84 and R85 are each independently selected from hydrogen, - (C1-C10) alkyl, aryl, - (C1-C10) alkaryl, - (C1-C10) aralkyl, carboxy, carbalkoxy, and halo. When t is one (1), groups (a), (b) , and (d) have acid linker lengths of 3, 3, and 2, respectively. The salts of the above tricyclics are an additional aspect of the invention. In those instances where the compounds of the invention possess acidic functional groups, various salts may be formed which are more water soluble and physiologically suitable than the parent compound. 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. Sodium salts are preferred. 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. R- and S- isomers and racemic mixtures are contemplated by this invention. A particular stereoisomer may be prepared by known methods using stereospecific reactions with starting materials containing asymmetric centers already resolved or, alternatively, by subsequent resolution of mixtures of stereoisomers using known methods. 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, 7Amsterdam 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. Examples of acid protecting groups include ester or amide derivatives of the acid group, such as, methyl, methoxymethyl, methyl-thiomethyl, tetrahydropyranyl, methoxyethoxymethyl, benzyloxymethyl, phenyl, aryl, ethyl, 2, 2, 2-trichloroethyl, 2-methylthioethyl, t-butyl, cyclopentyl, triphenylmethyl, diphenylmethyl, benzyl, trimethylsilyl, N, N-dimethyl, pyrrolidinyl, piperidinyl, or o-nitroanilide. A preferred acid-protecting group is methyl .

Scheme I cont. BBr, PG= oxyprotecting group; methyl, benzyl, isopropyl, allyl In a Lewis acid mediated acylation, starting material (1) is treated with a slight molar excess of a weak acid, preferably magnesium perchlorate, then reacted with an appropriately substituted glycidic where R 4' is preferably phenyl. The reaction is preferably conducted in an aprotic solvent, preferably acetonitrile, at temperatures of from about 0°C to 50°C. The arylglycidic alcohols used in this step are readily available as optically pure compounds [Katsuki, T; Sharpless, K. B. J. Am. Chem. Soc, 1980, 102, 5974] and this reaction is highly stereopspecific. For example, using the IS, 2S glycidic alcohol will give a final product having the R configuration at position 3, and using the 1R, 2R, glycidic alcohol will provide the final product having the S configuration at position 3 since this position is inverted by the epoxide opening reaction and unaffected during the course of all subsequent reactions. Conversion of dialcohol (2) to a suitable leaving group is achieved by refluxing with thiolcarbonyl diimidazole in a suitable aprotic solvent such as tetrahydrofuran (THF) . Reductive elimination of the leaving group of (3) to form olefin (4) is accomplished by heating with a suitable reducing agent such as trimethyl, triethyl or triphenyl phosphite. The reaction is preferably conducted at temperatures of from about 50° to 120 °C for extended periods of time, from about 20 to 24 hours, preferably about 22 hours. In a two step, one pot reaction, oxidation of (4) is accomplished by treating first with a borane reagent, preferably 9-borobicylo [3.3.1] nonane followed by treatment with hydrogen peroxide in the presence of an excess of a hydroxide base, preferably sodium hydroxide. Lithium hydroxide may also be employed. Reactions maybe run at temperatures of from about -10°C to 250°C, preferably at about 0°C. Preferably, the reactions are conducted in an aprotic solvent such as THF. Aromatization of the indole ring may be accomplished by oxidation of (5) with a slight excess, preferably 1.1 equivalents, of 2, 3-dichloro-5, 6-dicyano-l, 4-benzo quinone (DDQ) , at temperatures from about 50° to 110°C, preferably at about 70°C. The reaction is substantially complete in about 5 hours. Conversion of intermediate (6) to the alkylhalide (7) may be achieved by treatment with a reagent of the formula CX 4 , where X is halo, preferably chlorine, in the presence of an activating agent, preferably triphenylphosphine . The reaction may be conducted at room temperature and requires extended periods of time, up to about 16 hours, for completion. Free radical cyclization of (7) is generally accomplished by treatment first with a tin hydride reagent such as tributyl tinhydride, in the presence of a free radical initiatior such as 1, 1' azobis (cyclohexanecarbonitrile) (ACN) or 2,2'- azobisisobutyronitrile (AIBN) then with additional aliquots of ACN or AIBN added slowly over a period of about five hours. The reaction is substantially complete about one hour after the last addition of ACN or AIBN. The reaction is preferably conducted in an aprotic, high boiling organic solvent such as degassed toluene, at temperatures of about 110°C. Oxidation of indoline (8) to indole (9) is accomplished as described above, by oxidation with an oxidizing reagent such as DDQ. Other oxidizing agents are also suitable, however if DDQ is utilized, it is critical that a slight excess (about 1:1 equivalents) is employed. The reaction is preferably conducted in an organic solvent such as dioxane, usually under moderate reaction conditions. Deprotection of the oxy group of (9) is readily accomplished by treatment with an excess of from about 2 to 10 equivalents of boron tribromide.

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 sPLA2 with an 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 sepsis, septic shock, adult respiratory distress syndrome, pancreatitis, trauma- induced shock, asthma, rheumatoid arthritis, osteoarthritis, acute bronchitis, chronic bronchitis, Inflammatory Bowel Disease, apoptosis, stroke, cystic fibrosis, allergic rhinitis, acute bronchiolitis, chronic bronchiolitis, gout, spondylarthropathris, ankylosing spondylitis, Reiter' s syndrome, psoriatic arthropathy, enterapathric spondylitis, Juvenile arthropathy or juvenile ankylosing spondylitis, Reactive arthropathy, infectious or post-infectious arthritis, gonoccocal arthritis, tuberculous arthritis, viral arthritis, fungal arthritis, syphilitic arthritis, Lyme disease, arthritis associated with "vasculitic syndromes", polyarteritis nodosa, hypersensitivity vasculitis, Luegenec' s granulomatosis, polymyalgin rheumatica, joint cell arteritis, calcium crystal deposition arthropathris, pseudo gout, non-articular rheumatism, bursitis, tenosynomitis, epicondylitis (tennis elbow) , carpal tunnel syndrome, repetitive use injury (typing) , miscellaneous forms of arthritis, neuropathic joint disease (charco and joint) , hemarthrosis (hemarthrosic) , Henoch-Schonlein Purpura, hypertrophic osteoarthropathy, multicentric reticulohistiocytosis, arthritis associated with certain diseases, surcoilosis, hemochromatosis, sickle cell disease and other hemoglobinopathries, hyperlipoproteineimia, hypogammaglobulinemia, hyperparathyroidism, acromegaly, familial Mediterranean fever, Behat's Disease, systemic lupus erythrematosis, or relapsing polychondritis; and related diseases (preferably, sepsis, septic shock, adult respiratory distress syndrome, pancreatitis, trauma-induced shock, asthma, rheumatoid arthritis, osteoarthritis, acute bronchitis, chronic bronchitis, Inflammatory Bowel Disease) 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 sPLA2 may be readily determined by taking a sample of body fluid and assaying it for sPLA2 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. However it must be noted that the study of adverse conditions of the central nervous system in non-human animals is only now beginning, an that some instances of such treatments are coming into use. Accordingly, use of the present compounds in non-human animals is contemplated. 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 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. For example, 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 or II 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 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 IC5 0 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. Assay Example 2 Method: Male Hartley strain guinea pigs (500-700g) were killed by cervical dislocation and their heart and lungs removed intact and placed in aerated (95% 02 : 5% CO2) Krebs buffer. Dorsal pleural strips (4xlx25mm) were dissected from intact parenchymal segments (8x4x25mm) cut parallel to the outer edge of the lower lung lobes. Two adjacent pleural strips, obtained from a single lobe and representing a single tissue sample, were tied at either end and independently attached to a metal support rod. One rod was attached to a Grass force-displacement transducer Model FT03C, (product of Grass Medical Instruments Co., Quincy, MA, USA). Changes in isometric tension were displayed on a monitor and thermal recorder (product of Modular Instruments, Malvern, PA) . All tissues were placed in 10 ml jacketed tissue baths maintained at 37 °C. The tissue baths were continuously aerated and contained a modified Krebs solution of the following composition (millimolar) NaCl, 118.2; KC1, 4.6; CaCl2-2H2θ, 2.5; MgSθ4-7H2θ, 1.2; NaHC03, 24.8; KH2PO4, 1.0; and dextrose, 10.0. Pleural strips from the opposite lobes of the lung were used for paired experiments. Preliminary data generated from tension/response curves demonstrated that resting tension of 800mg was optimal. The tissues were allowed to equilibrate for 45 min. as the bath fluid was changed periodically. Cumulative concentration-response curves: Initially tissues were challenged 3 times with KC1 (40 mM) to test tissue viability and to obtain a consistent response. After recording the maximal response to KC1, the tissues were washed and allowed to return to baseline before the next challenge. Cumulative concentration-response curves were obtained from pleural strips by increasing the agonist concentration (sPLA2) in the tissue bath by half-logio increments while the previous concentration remained in contact with the tissues (Ref.l, supra.). Agonist concentration was increased after reaching the plateau of the contraction elicited by the preceding concentration. One concentration-response curve was obtained from each tissue. To minimize variability between tissues obtained from different animals, contractile responses were expressed as a percentage of the maximal response obtained with the final KC1 challenge. When studying the effects of various drugs on the contractile effects of sPLA2, the compounds and their respective vehicles were added to the tissues 30 minutes prior to starting the sPLA2 concentration-response curves. Statistical analysis: Data from different experiments were pooled and presented as a percentage of the maximal KC1 responses (mean ± S.E.). To estimate the drug induced rightward shifts in the concentration response curves, the curves were analyzed simultaneously using statistical nonlinear modeling methods similar to those described by Waud (1976), Equation 26, p. 163, (Ref.2). The model includes four parameters: the maximum tissue response which was assumed the same for each curve, the ED50 for the control curve, the steepness of the curves, and the pA2, the concentration of antagonist that requires a two-fold increase in agonist to achieve an equivalent response. The Schild slope was determined to be 1, using statistical nonlinear modeling methods similar to those described by Waud (1976), Equation 27, p. 164 (Ref. 2). The Schild slope equal to 1 indicates the model is consistent with the assumptions of a competitive antagonist; therefore, the pA2 may be interpreted as the apparent KB, the dissociation constant of the inhibitor. To estimate the drug-induced suppression of the maximal responses, SPLA2 responses (10 ug/ml) were determined in the absence and presence of drug, and percent suppression was calculated for each pair of tissues. Compounds of the instant invention were tested in Assay Example 2 and were found to be effective at concentrations below 20μM. Ref. 1 - Van, J.M. : Cumulative dose-response curves. II.
