BACKGROUND OF THE INVENTION
Phospholipases A.sub.2 (PLA.sub.2 's) are a class of enzymes which catalyze the hydrolysis of membrane phospholipids at the sn-2 position leading to free fatty acids and lysophospholipid. Arachidonic acid is stored in the cell membrane as an ester almost exclusively at the 2-position of phospholipids. PLA.sub.2 acts to release arachidonic acid from phospholipids in what is believed to be the rate controlling step which ultimately leads to the products of the arachidonic acid cascade. Free arachidonic acid is rapidly metabolized by cyclooxygenase to give prostaglandins and thromboxane or by lipoxygenases to form hydroxy fatty acids and leukotrienes. Prostaglandins and leukotrienes are important mediators of inflammation and hydroxy fatty acids such as leukotriene B.sub.4 act as chemotactic agents for neutrophils and eosinophils and may cause cell migration to sites of inflammation. Lysophospholipids are cytotoxic and have also been implicated in several inflammatory conditions. In addition, platelet activating factor (PAF) can be formed by the action of an acetyl transferase on a 1-alkyl-2-lysophospholipid. PAF is a potent platelet aggregating substance and causes various inflammatory conditions such as erythema, vascular permeability and cellular chemotaxis. These facts provide support for the utilization of an inhibitor of PLA.sub.2 's as therapy for various inflammatory conditions.

The compounds of formula 1 can be prepared as set forth in Schemes 1-16. ##STR5## wherein R.sub.2 ' is lower alkyl or benzyl and R.sub.3, R.sub.4, m are as previously described.
In Scheme 1 a substituted aniline of formula 2, which can be prepared according to one of the Schemes which follows, can be convened to the corresponding compound of the invention by a two step process. In the first step an aniline of formula 2 is convened to the corresponding dialkylated aniline of formula 3 by reaction with an excess of a bromo ester in the presence of a base such as 1,8-bis(dimethylamino)naphthalene (Proton Sponge) or an alkali metal carbonate in an anhydrous, polar, aprotic solvent such as acetonitrile, acetone or dimethylformamide (DMF) or mixtures thereof. The reaction is carried out at a temperature of from 56.degree.-100.degree.. Sodium iodide is usually added to facilitate the reaction. Alternatively, a compound of formula 2 can be convened to the corresponding monoalkylated aniline of formula 4 under similar reaction conditions but without using a large excess of the bromo ester. Intermediates of formulas 3 and 4 can be converted to the corresponding compounds of the invention of formula 1a and 1b by hydrolysis using an alkali metal hydroxide in a solvent mixture of water and a lower alkanol. In some cases, a co-solvent such as dioxane must be added to improve solubility. Hydrogenolysis can also be used for conversion of a compound of the formula 3 or 4 to the corresponding compound of formula 1a or 1b when the R.sub.2 ' group is benzyl. This is accomplished by shaking a solution of a compound of formula 3 or 4 with a palladium catalyst in a hydrogen atmosphere using an inert solvent such as ethyl acetate, tetrahydrofuran (THF) or DMF.
The substituted anilines of formula 2 required for the preparation of the compounds of the invention can be prepared as set forth in Schemes 2-9. ##STR6## wherein R.sub.3.sup.a and R.sub.4.sup.a are the same, and are CH.sub.3 (CH.sub.2).sub.n O--, R.sub.6 OOC(CH.sub.2).sub.0 O--, oleyloxy, linoleyloxy, R.sub.6 [O(CH.sub.2).sub.2 ].sub.q O--, R.sub.7 (CH.sub.2).sub.p O-- or CH.sub.3 (CH.sub.2).sub.n CHOHCH.sub.2 O--, R.sub.6 and R.sub.7 are as previously described, R' is benzyl or methyl, and R" is benzyl or t-butyl.
The process of Scheme 2 can be used for the preparation of disubstituted anilines of formula (2a) wherein R.sub.3.sup.a and R.sub.4.sup.a are the same. A known dihydroxy ester of formula 5 can be dialkylated to give the corresponding compound of formula 6 by heating with excess of the corresponding alkyl halide or epoxide using an alkali metal carbonate as a base in a solvent such as acetone or DMF or mixes thereof. The ester of formula 6 can be hydrolyzed to the corresponding acid of formula 7 under standard conditions using an alkali metal hydroxide in a solvent mixture of water and a lower alkanol with added dioxane to improve solubility, if needed. A benzoic acid of formula 7 can be convened to the corresponding carbamate of formula 8 using the Curtius Reaction under the following conditions. An acid of formula 7 is converted to the corresponding acyl azide using diphenylphosphoryl azide in an inert, anhydrous solvent such as toluene or benzene in the presence of a tertiary amine such as triethylamine at temperatures of from 0.degree.-30.degree.. Heating the acyl azide solution at 60.degree.-110.degree. causes rearrangement to the corresponding isocyanate. Addition of benzyl alcohol or t-butyl alcohol followed by continued heating at 60.degree.-110.degree. results in formation of the corresponding carbamic acid benzyl ester or t-butyl ester of formula 8. The conversion of a compound of formula 7 to the corresponding compound of formula 8 can also be carried out by heating a compound of formula 7, diphenylphosphoryl azide and triethylamine in t-butyl alcohol at 60.degree.-83.degree.. Finally, a carbamate of formula 8 can be convened to the corresponding disubstituted aniline of formula 2a by hydrogenolysis, if R" is benzyl, carried out by shaking with a palladium catalyst in a hydrogen atmosphere in an inert solvent such as ethyl acetate or THF. A carbamate of formula 8, if R" is t-butyl, is convened to the corresponding compound of formula 2a by treatment with trifluoroacetic acid in a solvent such as methylene chloride at a temperature of from 0.degree.-30.degree.. ##STR7## wherein R.sub.3.sup.b and R.sub.4.sup.b are different, and are CH.sub.3 (CH.sub.2).sub.n O--, R.sub.5 COO--, R.sub.5 HNCOO--, oleyloxy, linoleyloxy, R.sub.6 [O(CH.sub.2).sub.2 ].sub.q O--, R.sub.6 OOC(CH.sub.2).sub.0 O--, R.sub.7 (CH.sub.2).sub.p O-- or CH.sub.3 (CH.sub.2).sub.n CHOHCH.sub.2 O--, R' is benzyl or methyl or R" is benzyl or t-butyl.
The process of Scheme 3 can be used for the preparation of disubstituted anilines of formula 2b, wherein R.sub.3.sup.b and R.sub.4.sup.b are different. A known dihydroxy ester of formula 5 can be monoalkylated by heating with an equimolar amount of the corresponding alkyl halide using an alkali metal carbonate as the base in a solvent such as acetone or DMF or mixes thereof. The desired monoalkylation product of formula 9 can be separated from the dialkylation product and the starting material of formula 5 using standard separation techniques. Alkylation of a compound of formula 9 using the same conditions but with a different alkyl bromide then provides the corresponding compound of formula 10 which can be hydrolyzed or hydrogenolyzed to the corresponding acid of formula 11. An acid of formula 11 is subjected to the Curtius Reaction to give the corresponding carbamate 12, which can be converted to the disubstituted aniline of formula 2b, as described in Scheme 2. ##STR8## wherein X and Y are the same, and are OH or NH.sub.2, R.sub.3.sup.c and R.sub.4.sup.c are the same, and are R.sub.5 COO--, R.sub.5 NHCOO--, R.sub.5 CONH-- or R.sub.5 NHCONH--, R.sub.5 is as previously described, and R" is benzyl or t-butyl.
In Scheme 4, a known dihydroxy or diaminobenzoic acid of formula 13 can be convened to the corresponding compound of formula 14 by treatment with the corresponding acid chloride or isocyanate in the presence of a tertiary amine such as triethylamine and a solvent such as methylene chloride or THF at a temperature of from 0.degree.-30.degree.. The resulting acid of formula 14 when subjected to the Curtius Reaction under conditions described earlier provides the corresponding carbamate of formula 15 which can be convened to the substituted aniline of formula 2c, as in Scheme 2. ##STR9## wherein R.sub.3.sup.d and R.sub.4.sup.d are the same, and are R.sub.5 OOC--, R.sub.5 NHCO-- or [CH.sub.3 (CH.sub.2).sub.n ].sub.2 NCO--, and R.sub.5 is as previously described.

Catalytic hydrogenation of a compound of formula 18 using a palladium catalyst in a solvent such as ethyl acetate or THF gives the corresponding substituted aniline of formula 2d. ##STR10## wherein n is as previously described.

The invention also relates to salts of the compounds of formula 1 when they contain an acidic functionality, such as when R.sub.2 is hydrogen, which lends itself to salt formation with a base. Salts of the compounds of formula 1 which have a carboxy group are prepared by the reaction with a base having a non-toxic, pharmacologically acceptable cation. In general, any base which will form a salt with a carboxylic acid and whose pharmacologically properties will not cause an adverse physiological effect is within the scope of this invention.
Suitable bases thus include, for example, the alkali metal and alkaline earth metal hydroxides, carbonates or the like, for example, calcium hydroxide, sodium hydroxide, sodium carbonate, potassium carbonate or the like, ammonia, primary, secondary and tertiary amines, such as, monoalkylamines, dialkylamines, trialkylamines, for example, methylamine, diethylamine, triethylamine or the like, nitrogen containing heterocyclic amines, for example, piperidine or the like. A salt thus produced is the functional equivalent of the corresponding compound of formula 1 wherein R.sub.2 is hydrogen and one skilled in the art will appreciate that the variety of salts embraced by the invention is limited only by the criterion that a base employed in forming the corresponding salts be both non-toxic and physiologically acceptable.
The useful activity of the compounds of formula 1 as phospholipase A.sub.2 (PLA.sub.2) inhibitors can be demonstrated as hereinafter set forth.
The compounds of formula 1 are potent inhibitors of phospholipases A.sub.2 (PLA.sub.2 's) and are therefore useful in the treatment of inflammatory diseases, such as psoriasis, inflammatory bowel disease, asthma, allergy, arthritis, dermatitis, gout, pulmonary disease, myocardial ischemia, and trauma induced inflammation, such as spinal cord injury.
Assay for Inhibition of HSF-PLA.sub.2 In Vitro
The PLA.sub.2 used in this test is the extracellular enzyme obtained from human synovial fluid (HSF-PLA.sub.2).
The assay for HSF-PLA.sub.2 activity was a modification of the described method [Franson R., Dobrow R., Weiss, J., Elsbach P., and Weglick W. B., J. Lipid Res., 19, 18-23 (1978)] which was conducted using [1-.sup.14 C]-oleate-labelled E. coli substrate in excess at a final concentration of 20,000 dpm/ml. This was equivalent to 18.2 .mu.M of cell membrane phospholipid phosphorus and 2.times.10.sup.9 autoclaved E. coli/ml. The optimal conditions which were developed for the assay of HSF-PLA.sub. 2 inhibitors are summarized as follows. A total volume of 0.5 ml of reaction mixture typically had the following final composition: substrate (20,000 dpm/ml); enzyme (0.1% HSF, v/v); 2 mM CaCl.sub.2 ; 150 mM Na.sup.+ ; 50 mM sodium HEPES buffer, pH 7.3; and 1% dimethyl sulfoxide (DMSO, used to solubilize test inhibitors) in the presence or absence of inhibitor. The reaction was initiated by the addition of HSF-PLA.sub.2 and duplicate samples of the mixture were incubated in 13.times.100 mm glass tubes with shaking for 30 minutes at 37.degree. C. The reaction was terminated by the addition of 2.5 ml of chloroform-methanol (1 to 1.5, v/v). The extraction of lipids from the stopped reaction mixture was conducted by the further additions of 0.5 ml of chloroform and 1 ml of water with mixing. After centrifuging, the lower chloroform phase was transferred to smaller glass tubes and the solvent was evaporated to dryness with a nitrogen stream. The extracted lipid residue was redissolved in 50 .mu.l of a solution containing carrier oleic acid (0.2 mg/ml) of chloroform-methanol [9 to 1, v/v]). The whole lipid extract was applied to a preactivated (30 minutes at 110.degree. C.) silica gel-impregnated glass fiber thin layer chromatography sheet (ITLC type SG sheet from Gelman Sciences Inc., Ann Arbor, Mich.) using hexane-acetic acid (100 to 1, v/v) as the developing solvent. This TLC system rapidly (6 minutes) resolved the enzymatically released product, .sup.14 C-oleic acid, from the unreacted .sup.14 C-phospholipid substrate. The unsaturated lipids were located on the chromatogram by a brief exposure to iodine vapor. The oleic acid zone (R.sub.f value 0.95) and phospholipid zone (origin) were cut out, chopped into small pieces, shaken with 2 ml of ethanol-water (80 to 20, v/v) and 15 ml of Aquasol and counted for radioactivity. A control incubation of substrate in the absence of HSF-PLA.sub.2 was performed in each experiment. The PLA.sub.2 activity of the human synovial fluid was corrected for this small control value. In the absence of inhibitors, these optimal conditions resulted in approximately 18% hydrolysis of substrate (corrected for a substrate blank of <2%). The specific activity of PLA.sub.2 in the pooled human synovial fluid under the optimal assay conditions was 49.2 nmoles [1-.sup.14 C]-oleic acid released hour.sup.-1 mg.sup.-1. The IC.sub.50 (.mu.M concentration of test compound that produces 50% inhibition of PLA.sub.2 activity) was determined for each test compound. The results are reported in Table I.
Phospholipase A.sub.2 Rat Paw Edema
Representative compounds of the invention were tested in rats to determine their ability to inhibit the acute inflammatory response induced by the injection of snake venom phospholipase A.sub.2. Test compounds are administered intraperitoneally or orally to groups of seven Lewis rats (.apprxeq.200 gm) 1 hr prior to phospholipase A.sub.2 administration. The test compounds are dissolved in dimethyl sulfoxide for intraperitoneal administration and dissolved or suspended in Labrafil M-1944CS for oral administration. At 0 hr, 5 ug (10 units) of purified phospholipase A.sub.2 from Naja naja venom (Sigma Chem. Co.) dissolved in 0.1 mL of pyrogen free saline is injected subplantarly into the right hind paw to elicit the inflammatory response. The volume (in mL) of the right hind paw is measured by immersion of the paw to the level of the lateral malleolus in an aqueous plethysmometer immediately prior to the injection of phospholipase A.sub.2 and then at 0.5, 2 and 4 hr after phospholipase A.sub.2 injection. The paw edema is calculated by subtracting the zero time reading from the readings taken after injection. The percent change of the edema volume from the vehicle treated control is calculated to determine the activity of the test compound. Statistical analysis of the mean paw edema values of the control versus the treated groups is performed using Student's t-test. Significance of changes from mean value for vehicle-treated animals (*p<0.05, **p<0.01, ***p<0.001, ns/not significant).
Croton Oil Mouse Ear Edema Test
The croton oil-induced mouse ear edema test, a model of irritant-induced contact dermatitis, has also been used for evaluation of the PLA.sub.2 inhibitors by the topical route of administration. This test was carried out as described in the following references:
Weirich, E. G., Longauer, J. K and Kirkwood, A. A. Arch Dermatol. Res. 259: 141-149, 1977.
Tubaro, A., Dri, P., Delbello, G., Zilli, C. and Della Loggia, R. Agents and Actions, 17: 347-349, 1985.
The major active ingredient in croton oil is the tumor promoter 12-O-tetradecanoylphorbol 13-acetate (TPA) and the topical application TPA to mouse skin has been reported to cause an increase in epidermal PGE.sub.2 production as well as an increase in epidermal cell membrane PLA.sub.2 activity. Indomethacin, an inhibitor of prostaglandin synthesis, prevented the TPA-mediated increase in epidermal PGE.sub.2 levels as well as the TPA-mediated induction of epidermal cell ornithine decarboxylase. Furthermore, the application of PGE.sub.2 to mouse skin countered the inhibitory effect of indomethacin upon TPA-stimulated cellular proliferation. Taken together these dam suggest that the croton oil mouse ear edema test is a valid model for the topical evaluation d PLA.sub.2 inhibitors.
Twenty five .mu.l of a 1% croton oil solution [dissolved in a mixture of pyridine/water/diethyl ether at a ratio of 5/20/75 (croton oil vehicle)]'are applied to the outer side of the right ear of 3-4 week old male CD-1 mice (8 animals per group). The test compounds are dissolved directly in the 1% croton oil solution at various concentrations and coapplied. Control animals receive 25 .mu.l of croton oil vehicle on the right ear. Biopsy punches are removed at 6 hours from the right ear of the animals using a 6 mm skin trephine (Roboz, Washington, D.C.) and the wet weight of the ear punches is determined. The weight of the biopsy punches is a measure of ear inflammation, primarily edema. The data are expressed as percent inhibition relative to control groups.
The in vivo activity of representative compounds of formula 1 in the PLA.sub.2 rat paw edema and the croton oil ear edema tests are reported in Table I.

Rat Carrageenan Paw Edema
Representative compounds of the invention were tested in rat carrageenan-induced paw edema to determine their ability to inhibit this acute inflammatory response. Test compounds are administered intraperitoneally or orally to groups of seven Lewis rats (.apprxeq.200 gm) 1 hr prior to carrageenan administration. The test compounds are dissolved in dimethyl sulfoxide for intraperitoneal administration and dissolved or suspended in Labrafil M-19944CS for oral administration. At 0 hour, 0.1 mL of 1% carrageenan dissolved in pyrogen free saline is injected subplantarly into the right hind paw to elicit the inflammatory response. The volume (in mL) of the right hind paw is measured by immersion of the paw to the level of the lateral malleolus in an aqueous plethysmometer immediately prior to the injection of carrageenan and then at 1, 2 and 4 hr after carrageenan injection. The paw edema is calculated by substracting the zero time reading from the readings taken after injection. The percent change of the edema volume from the vehicle treated control is calculated to determine the activity of the test compound. Statistical analysis of the mean paw edema values of the control versus the treated groups are performed using Student's t-test.
The results obtained are set forth in Table III.

Acetic Acid-Induced Colitis in Rats
The rat acetic acid-induced colitis bioassay has been described by J. E. Krawisz, et al. in Amer. J. Proc. Castro. Col. Rec. Surg. 31: 11-18 (1980), and by P. Sharon and W. F. Stenson in Gastroenterology 88: 55-63 (1985) and 86: 453-460 (1984). Acetic acid-induced colitis is characterized by the movement of inflammatory cells into the colon, with the number of such cells in the mucosa being measured by the activity of myeloperoxidase, a marker enzyme for these cells. Positive desirable activity is indicated by a reduction in the high levels of myeloperoxidase caused by acetic acid. Male rats (Sprague-Dawley), weighing 150 to 300 g, were pretreated twice daily for two days with either the vehicle (water, or dimethylsulfoxide) or the test inhibitor compound suspended in water or dissolved in dimethylsulfoxide and orally administered. On the third day, the animals were dosed the same as on the previous two days, anesthetized with metofane, and 2 ml of 2.5% acetic acid was injected..by syringe into the colonic lumen, followed immediately by 3 ml of air and a rinse consisting of 3 ml of phosphate-buffered saline (the acetic acid is present in the lumen for a sufficient period to cause inflammation without producing severe necrosis or irreversible damage). The animals were administered a second dose of the test compound in the same amount about 16 hours later. Then 24 hours after the acetic acid treatment, the animals were sacrificed. The colonic mucosa was surgically removed and homogenized in an aqueous buffer at pH 6 with a Tissumizer or similar device and myeloperoxidase was measured in the homogenate using o-phenylenediamine as a cromagen, as described by A. Voller, D. E. Bidwell and A. Bartlett in "The Enzyme Linked Immunosorbent Assay (ELISA)", Zoological Soc., London, 1979, pages 29-30. Control animals were pretreated with the vehicle and saline in place of acetic acid.
Data for representative compounds of this invention is reported in Table V.

In practice of the invention, the dose of a compound of formula 1 or a salt thereof to be administered and the frequency of administration will be dependent on the potency and duration of activity of the particular compound of formula 1 or salt to be administered and on the route of administration, as well as the severity and nature of the condition and age of the mammal to be treated and the like. Oral doses of a compound of formula 1 or a salt thereof contemplated for use in practicing the invention can be in the range of from 10 mg to about 2.0 g per day, preferably about 50 mg to about 1 gm per day, either as a single dose or in divided doses.
A compound of formula 1, or a salt or a composition containing a therapeutically effective mount of a compound of formula 1, (an enantiomer of a racemate, where applicable) or a salt thereof can be administered by methods well known in the art. Thus, a compound of formula 1, or a salt thereof can be administered either singly or with other pharmaceutical agents, for example, antihistamines, mediator release inhibitors, methyl xanthines, beta agonists or antiasthmatic steroids such as prednisone and prednisolone, orally, parenterally, rectally, or by inhalation, for example in the form of an aerosol, micropulverized powder or nebulized solution. For oral administration, they can be administered in the form of tablets, capsules, for example, in admixture with talc, starch, milk sugar or other inert ingredients, that is, pharmaceutically acceptable carriers, or in the form of aqueous solutions, suspensions, elixirs or aqueous alcoholic solutions, for example, in admixture with sugar or other sweetening agents, flavoring agents, colorants, thickeners and other conventional pharmaceutical excipients. For parenteral administration, they can be administered as solutions or suspension, for example, as an aqueous or peanut oil or suspension using excipients and carriers conventional for this mode of administration. For administration as aerosols, they can be dissolved in a suitable pharmaceutically acceptable solvent, for example, ethyl alcohol or combinations of miscible solvents, and mixed with a pharmaceutically acceptable propellant. Such aerosol compositions are packaged for use in pressurized container fined with an aerosol valve suitable for release of the pressurized composition. Preferably, the aerosol valve is a metered valve, that is one which on activation releases a predetermined effective dose of the aerosol composition.
EXPERIMENTAL SECTION
The Examples which follow further illustrate the invention. All temperatures set forth in the specification and the Examples are in degrees Centigrade. Melting points were taken on a Thomas Hoover capillary melting point apparatus and are uncorrected. All compounds were characterized by proton magnetic resonance spectra taken on a Varian XL-200 or XL-400 spectrometer and electron impact or fast atom bombardment (+FAB) mass spectra taken on either VG ZAB-1F or VG 70E-HF mass spectrometers. Preparative high-pressure liquid chromatography (HPLC) was performed on silica gel Prep-Pak 500 cartridges using a Waters Associates Prep LC 500A. Extracts were dried over anhydrous magnesium sulfate unless otherwise noted.

EXAMPLE 3
3,5-Bis(decyloxy)phenylcarbamic acid phenylmethyl ester
To a stirred, ice bath cooled solution of 5.0 g (0.0115 mol) of 3,5-bis(decyloxy)benzoic acid in 100 ml of anhydrous toluene was added dropwise 3.0 ml (0.0138 mol) of diphenylphosphoryl azide followed by dropwise addition of 1.9 ml (0.0138 mol) of triethylamine. The reaction mixture was stirred in the ice bath for 75 minutes and then was heated at 90.degree. for 2 hours. Benzyl alcohol (100 ml) was added and the solutionwas stirred and heated at 90.degree. for 3.5 hours. The solvent was removedunder reduced pressure and most of the excess benzyl alcohol was removed at80.degree./0.1 mm. Sodium bicarbonate solution (100 ml) was added to the residue and the product was extracted with ethyl acetate. The dried extract was concentrated at reduced pressure to an oil which was purified by HPLC using 25% hexane-ethyl acetate to give 4.87 g (79% yield) of 3,5-bis(decyloxy)phenylcarbamic acid phenylmethyl ester as an oil.
