## Abstract

This invention is in the field of antiinflammatory pharmaceutical agents and specifically relates to compounds, compositions and methods for treating disorders mediated by cyclooxygenase-2 or 5-lipoxygenase, such as inflammation.

## Background
This invention is in the field of antiinflammatory pharmaceutical agents and specifically relates to compounds, compositions and methods for treating disorders mediated by cyclooxygenase-2 or 5-lipoxygenase, such as inflammation and allergic conditions such as asthma.

Prostaglandins play a major role in the inflammation process, and the inhibition of prostaglandin production, especially production of PGG.sub.2, PGH.sub.2 and PGE.sub.2, has been a common target of antiinflammatory drug discovery. However, common non-steroidal antiinflammatory drugs (NSAIDs) that are active in reducing the prostaglandin-induced pain and swelling associated with the inflammation process are also active in affecting other prostaglandin-regulated processes not associated with the inflammation process. Thus, use of high doses of most common NSAIDs can produce severe side effects, including life threatening ulcers, that limit their therapeutic potential. An alternative to NSAIDs is the use of corticosteroids, which have even more drastic side effects, especially when long term therapy is involved.

Previous NSAIDs have been found to prevent the production of prostaglandins by inhibiting enzymes in the human arachidonic acid/prostaglandin pathway including the enzyme cyclooxygenase (COX). The recent discovery of an inducible enzyme associated with inflammation (named "cyclooxygenase-2 (COX-2)" or "prostaglandin G/H synthase II") provides a viable target of inhibition which more effectively reduces inflammation and produces fewer and less drastic side effects.

In another portion of the arachidonic acid pathway, physiologically active leukotrienes, such as leukotriene B.sub.4 (LTB.sub.4), leukotriene C.sub.4 (LTC.sub.4) and leukotriene D.sub.4 (LTD.sub.4) and other metabolites, are produced by the 5-lipoxygenase-mediated (5-LO) oxidation of arachidonic acid. These leukotrienes have been implicated in various inflammation-related disorders and allergic diseases, and thus compounds which inhibit 5-lipoxygenase are useful in the treatment of disease states in which leukotrienes play an important role.

It is believed that selective dual inhibitors of both cyclooxygenase-2 and 5-lipoxygenase, which affect the two enzymes at low concentrations, will more completely and permanently affect the damage caused by the various diseases and disorders mediated by cyclooxygenase-2 and 5-lipoxygenase but without the gastrointestinal side effects associated with traditional NSAIDs.

The references below that disclose antiinflammatory activity, show continuing efforts to find a safe and effective antiinflammatory agent. The novel compounds disclosed herein are such safe and also effective antiinflammatory agents furthering such efforts. The invention's compounds are found to show usefulness in vivo as antiinflammatory agents with minimal side effects. The compounds disclosed herein preferably selectively inhibit cyclooxygenase-2 over cyclooxygenase-1.

Compounds which selectively inhibit cyclooxygenase-2 have been described in U.S. Pat. Nos. 5,380,738, 5,344,991, 5,393,790 and WO documents WO94/15932, WO94/27980, WO95/00501, WO94/13635, WO94/20480, and WO94/26731.

Compounds which inhibit 5-lipoxygenase have been described in U.S. Pat. Nos. 5,364,877, 5,302,603, 5,234,950, 5,098,932 and 5,354,865, among others.

Compounds which inhibit cyclooxygenase and 5-lipoxygenase have been described in U.S. Pat. Nos. 5,298,521, 5,242,940, 5,234,939, and 5,356,898, among others. However, these previous mixed inhibitors do not selectively inhibit cyclooxygenase-2 and therefore still cause the gastrointestinal side effects which substantially reduce their usage and effectiveness.

The invention's compounds are found to show usefulness in vivo as dual inhibitors of cyclooxygenase-2 and 5-lipoxygenase with minimal side effects.

The present invention comprises a pharmaceutical composition comprising a therapeutically-effective amount of a compound of Formula I in association with at least one pharmaceutically-acceptable carrier, adjuvant or diluent.

The present invention also comprises a method of treating inflammation or inflammation-associated disorders in a subject, the method comprising administering to the subject having or susceptible to such inflammation or disorder a therapeutically-effective amount of a compound of Formula I. The method includes prophylactic or chronic treatment, especially in the case of arthritis and other inflammatory conditions which can lead to deterioration in the joints.

Also included in the family of compounds of Formula I are the stereoisomers and tautomers thereof. Compounds of the present invention can possess one or more asymmetric carbon atoms and are thus capable of existing in the form of optical isomers as well as in the form of racemic or nonracemic mixtures thereof. Accordingly, some of the compounds of this invention may be present in racemic mixtures which are also included in this invention. The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example by formation of diastereoisomeric salts by treatment with an optically active acid or base. Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric and camphorsulfonic acid and then separation of the mixture of diastereoisomers by crystallization followed by liberation of the optically active bases from these salts. A different process for separation of optical isomers involves the use of a chiral chromatography column optimally chosen to maximize the separation of the enantiomers. Still another available method involves synthesis of covalent diastereoisomeric molecules by reacting an amine functionality of precursors to compounds of Formula I with an optically pure acid in an activated form or an optically pure isocyanate. Alternatively, diastereomeric derivatives can be prepared by reacting a carboxyl functionality of precursors to compounds of Formula I with an optically pure amine base. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization or sublimation, and then hydrolyzed to deliver the enantiomerically pure compound. The optically active compounds of Formula I can likewise be obtained by utilizing optically active starting materials. These isomers may be in the form of a free acid, a free base, an ester or a salt.

Synthetic Scheme II shows the preparation of pyrazole compounds embraced by Formula I where R is Ar or Z (as defined in Scheme I), and R.sup.a is a radical defined above for the substituents optionally substituted on A. In step 1, ketone 4 is treated with a base, preferably NaOMe or NaH, and an ester, or ester equivalent, to form the intermediate diketone 5 (in the enol form) which is used without further purification. In step 2, diketone 5 in an anhydrous protic solvent, such as absolute ethanol or acetic acid, is treated with the hydrochloride salt or the free base of a substituted hydrazine at reflux to afford a mixture of pyrazoles 6 and 7. Recrystallization from diethyl ether/hexane or chromatography affords 6 usually as a solid. Similar pyrazoles can be prepared by methods described in U.S. Pat.

Scheme III shows the four step procedure for forming pyrazoles 11 of the present invention (where R.sup.b is alkyl) from ketones 8. In step 1, ketone 8 is reacted with a base, such as lithium bis(trimethylsilyl)amide or lithium diisopropylamide (LDA) to form the anion. In step 2, the anion is reacted with an acetylating reagent to provide diketone 9. In step 3, the reaction of diketone 9 with hydrazine or a substituted hydrazine, gives pyrazole 10. In step 4, the pyrazole 10 is oxidized with an oxidizing reagent, such as Oxone.RTM. (potassium peroxymonosulfate), 3-chloroperbenzoic acid (MCPBA) or hydrogen peroxide, to give a mixture of the desired 3-(alkylsulfonyl)phenyl-pyrazole 11 and the 5-(alkylsulfonyl)phenyl-pyrazole isomer. The desired pyrazole 11, usually a white or pale yellow solid, is obtained in pure form either by chromatography or recrystallization.

Alternatively, diketone 9 can be formed from ketone 8 by treatment with a base, such as sodium hydride, in a solvent, such as dimethylformamide, and further reacting with a nitrile to form an aminoketone. Treatment of the aminoketone with acid forms the diketone 9. Similar pyrazoles can be prepared by methods described in U.S. Pat. No. 3,984,431 which is incorporated by reference. ##STR14##

Some of the suitable solvents for this reaction are isopropanol, acetone and dimethylformamide. The reaction may be carried out at temperatures of about 20.degree. C. to about 90.degree. C. In step 3, the 4,5-dihydroimidazoles 31 may be dehydrated in the presence of an acid catalyst such as 4-toluenesulfonic acid or mineral acids to form the 1,2-disubstituted imidazoles 32 of the invention.

Reaction of cyanohydrin 34 with a strong base followed by treatment with benzaldehyde 35 (where R.sup.2 is alkyl) and using both acid and base treatments, in that order, on workup gives benzoin 36. Examples of strong bases suitable for this reaction are lithium diisopropylamide (LDA) and lithium hexamethyldisilazane. Benzoin 36 may be converted to benzil 37 by reaction with a suitable oxidizing agent, such as bismuth oxide or manganese dioxide, or by a Swern oxidation using dimethyl sulfoxide (DMSO) and trifluoroacetic anhydride. Benzil 37 may be obtained directly by reaction of the anion of cyanohydrin 34 with a substituted benzoic acid halide. Any of compounds 36 and 37 may be used as intermediates for conversion to imidazoles 38 (where R.sup.2 is alkyl) according to chemical procedures known by those skilled in the art and described by M. R. Grimmett, "Advances in Imidazole Chemistry" in Advances in Heterocyclic Chemistry, 12, 104 (1970). The conversion of 37 to imidazoles 38 is carried out by reaction with ammonium acetate and an appropriate aldehyde (RYCHO) in acetic acid. Benzoin 36 may be converted to imidazoles 38 by reaction with formamide. In addition, benzoin 36 may be converted to imidazoles by first acylating with an appropriate acyl group (RYCO--) and then treating with ammonium hydroxide. Those skilled in the art will recognize that the oxidation of the sulfide (where R.sup.2 is methyl) to the sulfone may be carried out at any point along the way beginning with compounds 35, and including oxidation of imidazoles 38, using, for examples, reagents such as hydrogen peroxide in acetic acid, m-chloroperoxybenzoic acid (MCPBA) and potassium peroxymonosulfate (OXONE.RTM.).

Diaryl/heteroaryl pyridines can be prepared by the methods described in U.S. Pat. Nos. 5,169,857, 4,011,328, and 4,533,666, which are incorporated by reference. For example, Synthetic Scheme XII shows the procedure used to prepare 3-alkylcarbonylaminoalkyl pyridine antiinflammatory agents 53, 3-haloalkyl pyridine antiinflammatory agents 55, 3-hydroxyalkyl pyridine antiinflammatory agents 56, heteroatom substituted 3-alkyl pyridine antiinflammatory agents 58 and 3-aryloxyalkyl pyridine antiinflammatory agents 59 from the corresponding carbonitriles 51. The 3-alkylcarbonylaminoalkyl pyridine antiinflammatory agents 53 (where R' is alkyl) are prepared in a two step procedure from the carbonitriles 51. In step one, the carbonitrile 51 is reduced using reducing agents, such as diisobutyl aluminum hydride (DIBAL) in a solvent such as toluene or boranes in a solvent such as tetrahydrofuran, at room temperature or reflux to form the aminoalkyl pyridine 52. Additional reducing reagent may be added to the solution. In step two, an acid chloride is added to the aminoalkyl pyridine 52 in a solvent such as ethyl ether or tetrahydrofuran and stirred to form the alkylcarbonylaminoalkyl pyridines 53. The 3-haloalkyl pyridine antiinflammatory agents 55 are prepared in a two step procedure from the carbonitriles 51. In step one, the carbonitriles 51 are reduced using agents, such as diisobutyl aluminum hydride (DIBAL) in a solvent such as toluene, at room temperature to form the aldehydes 54. The 3-hydroxyalkyl pyridines 56 also can be isolated from this reaction. In step two, a halogenating agent, such as diethylamino sulfur trifluoride (DAST) is added to the aldehyde 54 to form the haloalkyl pyridines 55. Reduction of aldehydes 54 with agents such as diisobutyl aluminum hydride (DIBAL) followed by methanol and water in methanol to yield the 3-hydroxyalkyl pyridines 56. Compound 56 is convertible to alkoxyalkyl and aralkoxyalkyl compounds 59 by sequential treatment first with a base and then with an alkyl or aralkyl halide. An example of a suitable base is sodium hydride. Examples of alkyl and aralkyl halides are methyl iodide and benzyl chloride. Alternatively, compound 56 may be converted to the haloalkyl compound 57 using a suitable halogenating agent, such as thionyl chloride. Under such circumstances, the hydrochloride salt may be isolated. This in turn may be converted to compounds 58 by reaction with the appropriate alcohol, thiol, or amine. It may be advantageous to carry out this reaction in the presence of a base. Examples of suitable alcohols are methanol, ethanol, benzyl alcohol and phenol. Examples of suitable thiols are n-butyl mercaptan, benzylthiol and thiophenol. Examples of suitable amines are dimethylamine, benzylamine, N-methylbenzylamine, aniline, N-methylaniline and diphenylamine. Examples of suitable bases are sodium hydride and potassium carbonate. Alternatively, amines are accessible by reaction of aldehyde 54 with a primary or secondary amine in the presence of a reducing agent. Examples of suitable primary amines are methyl amine and ethylamine. An example of a suitable secondary amine is dimethylamine. Suitable reducing agents include sodium cyanoborohydride and sodium borohydride. ##STR23##

Scheme XIII shows a method to form the alkylsulfonylphenyl substituted heterocycles 61 of the current invention by oxidation of alkylthio or alkylsulfinyl derivatives 60. Aqueous hydrogen peroxide (30%) is added to a suspension of a (methylthio)phenyl substituted heterocycle 60 in acetic acid. The mixture is stirred while heating to about 100.degree. C. for about 2 hours. Alternatively, m-chloroperoxybenzoic acid (MCPBA), and other oxidizing agents [potassium peroxymonosulfate (OXONE.RTM.)] can be used to form the sulfonyl radicals ##STR24##

Synthetic Scheme XIV shows the three step procedure used to prepare sulfonamide antiinflammatory agents 63 and the two step procedure used to prepare fluoromethyl sulfone antiinflammatory agents 64 from their corresponding methyl sulfones 62. In step one, THF solutions of the methyl sulfones 62 at -78.degree. C. are treated with an alkyllithium reagent, e.g., methyllithium, n-butyllithium, etc. In step two, the anions generated in step one are treated with an organoborane, e.g., triethylborane, tributylborane, etc., at -78.degree. C. then allowed to warm to ambient temperature prior to stirring at reflux. In step three, an aqueous solution of sodium acetate and hydroxylamine-O-sulfonic acid is added to provide the corresponding sulfonamide antiinflammatory agents 63 of this invention. As an alternative to the borane chemistry found in step two above, the base treated sulfone is reacted with an alkylsilane, such as (iodomethyl)trimethylsilane or (chloromethyl)trimethylsilane, at room temperature to give a silylalkylsulfone. The silylalkylsulfone is converted to a sulfinic acid salt by heating to about 90.degree. C. with tetrabutylammoniumfluoride. Treatment proceeds as in step three above to produce the sulfonamide.

Alternatively, the anion solutions generated in step one may be warmed to 0.degree. C. and treated with N-fluorodibenzenesulfonamide to provide the corresponding fluoromethyl sulfone antiinflammatory agents 64 of this invention. ##STR25##

Synthetic Scheme XV shows the four step procedure used to prepare anti-inflammatory compound of Formula II. In step one, a dichloromethane solution of 1-(substitutedphenyl)-2-hydroxy-2-[4-(methylsulfonyl)phenyl]ethanone 65 (described in U.S. Pat. No. 5,380,738) is treated with benzyloxyacetyl chloride in the presence of pyridine base to provide 2-benxyloxymethyl-4-(substitutedphenyl)-5-[4-(methylsulfonyl)phenyl]oxazol e 66 in good yield. In step two, the benzyloxy group is removed by hydrogenolysis in the presence of a catalytic amount of 10% palladium on charcoal to provide the hydroxymethyl compound 67. In step three, the hydroxymethyl compound 67 is treated with a solution of methanesulfonyl chloride in the presence of triethylamine base to produce the unstable mesylate 68 that is used directly in the next step. In step four, a mixture of the mesylate and a 3,4,5,6-tetrahydro-2H pyran in dimethylformamide (DMF) is treated with potassium carbonate to effect ether formation and provide the anti-inflammatory agents 69 (where R.sup.f is halo, alkoxy, or alkyl) of the present invention. ##STR26##

Synthetic Scheme XVI shows the four step procedure that is used to prepare anti-inflammatory compound of Formula II. In step one, benzoin 70 is mixed with ethyl carbamate (urethane) and heated to reflux to provide oxazolone 71 in high yield. In step two, oxazolone 71 is treated with a mixture of phosphorus oxychloride and triethylamine base to produce 2-chloro-5-phenyloxazole 72. In step three, 2-chloro-5-phenyloxazole 72 is treated first with chlorosulfonic acid to effect regioselective chlorosulfonation, followed by treatment with aqueous ammonia provides 2-chloro-5-(4-sulfonamido)phenyloxazole 73 in high yield. In step four, 2-chloro-5-(4-sulfonamido)phenyloxazole 73 and a tetrahydro-2H-pyran is treated with potassium carbonate to effect ether formation and provide the anti-inflammatory agents of the present invention 74. ##STR27##

Synthetic Scheme XVII shows a four step method of making the pyrazole phenylethers 79 of the present invention. In step 1, the dione 76 is formed from ketone 75 through the addition of a base, such as lithium bis(trimethylsilyl)amide or lithium diisopropylamide (LDA), followed by reacting with an appropriate acetylating reagent, such as (CO.sub.2 CH.sub.3).sub.2. Treatment of the dione 76 with a phenylhydrazine yields the pyrazole ester 77. The pyrazole ester 77 is first treated with base to hydrolyze the ester and is then reduced to the alcohol 78 by treatment with borane in THF. In step four, the alcohol 78 is treated with methanesulfonyl chloride in the presence of triethylamine base to produce the unstable mesylate that is directly reacted with a 3,4,5,6-tetrahydro-2H pyran in dimethylformamide and K.sub.2 CO.sub.3 to effect ether formation and provide the anti-inflammatory agents 79 of the present invention. ##STR28##

Scheme XVIII shows a procedure for forming an alkynyl oxazole 84 (where R.sup.2 is amino), similar to that shown in Scheme V above. The ketone sulfonamide 81 is formed from ketone 80 through chlorosulfonation and ammonolysis with ammonium hydroxide in a solvent such as acetone. The ketone sulfonamide 81 is halogenated, such as with HBr in acetic acid and bromine, to form the haloketone sulfonamide 82. Substitution with butynoic acid in the presence of K.sub.2 CO.sub.3, a crown ether, such as 18-crown-6, and dimethylacetamide (DMA) yields the alkynyl ketoester 83. Conversion of the alkynyl ester 83 to the alkynyl oxazole 84 proceeds as previously described in Scheme V. ##STR29##

Synthetic Scheme XIX shows the procedures for forming heterocycloalkynylethers 87, heterocyclotriazole ethers 88 and heterocycloalkylethers 89, from the corresponding alkynes 85. The alkynes 85 are halogenated such as with N-bromosuccinimide (NBS) and 2,2'-azobis(2-methylpropionitrile) (AIBN) to form the haloalkynes 86. Substitution with the appropriate aryl or aralkyl alcohols in the presence of potassium carbonate yields the alkynyl ethers 87 of the present invention. The alkynylethers 87 can be converted to heterocyclo-containing spacers 88 by treatment with azidotrimethylsilane, followed by acid. Alternatively, the alkynylethers 87 can be reduced, such as with hydrogen in the presence of catalyst, such as palladium, to yield the heterocycloalkylethers 89. ##STR30##

Scheme XX shows another method of forming the alkynylethers 92, alkylethers 93, alkenylethers 94 and the diols 95 of the present invention from the appropriate alkynes 90. In Step one, the alkynes 90 (where P is a protecting group such as tetrahydropyranyl, trialkylsilyl, tert-butyldimethylsilyl or diphenylalkylsilyl) are acid treated to form the alkynyl alcohols 91. Substitution of the alcohol 91 with aralkyl halides or heteroaryl halides in the presence of 1,8-diazabicyclo[5.4.0]undecane (DBU) yields the propynylethers 92 of the present invention. Reduction of the alkynylethers 92 with hydrogen in the presence of metal catalyst yields the alkylethers 93. Alternatively, treatment with diimide reduces the alkynylethers 92 to the alkenylethers 94. Oxidation of the alkenylether 94, such as with osmium tetraoxide and hydrogen peroxide, yields the diols 95 of the present invention. ##STR31##

Additional antiinflammatory agents containing various substituted alkylether spacer radicals including carbonylalkylethers 98, aminoalkylethers 100, hydroxyalkylethers 101, oxyiminoalkylethers 99, and amidoalkylethers 102, can be prepared from ketones 96, by the procedures shown in Scheme XXI. The ketones 96 are halogenated to form halomethylketone 97 such as by treatment with NBS in the presence of AIBN. Substitution of appropriate alcohols with the halides 97 in the presence of base, such as potassium carbonate, generates the ketoalkylethers 98. The ketoalkylethers 98 can be converted to the oxyimino-containing spacers 99 (where R.sup.g is alkyl) by treatment with substituted oxyamines, such as hydroxylamine. Hydroxyalkyl spacers 101 can be prepared by reducing the carbonyl in the ketoalkylethers 99 such as with sodium borohydride. Amination of the ketoalkylethers 99 by reaction with ammonium acetate and sodium cyanoborohydride in the presence of acetic acid generates the aminoalkylethers 100. Acetylation of the aminoethers 100 by acid chlorides or anhydrides in the presence of base, such as trialkylamines, produces the amidoalkylethers 102. ##STR32##

Scheme XXII shows the preparation of ethers 105 and amides 107 antiinflammatory agents of the present invention. Esters 103 where R.sup.i is alkyl, can be converted to the alcohols 104 by treatment with a reducing agent, such as DIBAL-H. The ethers 105 are formed by reacting with an aralkyl halide in the presence of base. Alternatively, the esters 103 can be hydrolyzed to the acids 106 with base such as LiOH. Amides 107 are formed from the acid 106 by treatment with thionyl chloride to form the acid chlorides, followed by substitution with aralkylamines. ##STR33##

Scheme XXIII shows the preparation of the antiinflammatory esters 109 and amides 110 of the present invention. Base treatment of ester 108, such as with sodium hydride, followed by addition of an aralkyl halide or heteroaralkyl halide forms the ester 109. Formation of the amide 110 from the esters 109 occurs in a three step procedure. Treatment with base, such as lithium hydroxide, and thionyl chloride yields the acid chloride. Addition of an amine yields the amide 110.

Rat Carrageenan Foot Pad Edema Test

The carrageenan foot edema test was performed with materials, reagents and procedures essentially as described by Winter, et al., (Proc. Soc. Exp. Biol. Med., 111, 544 (1962)). Male Sprague-Dawley rats were selected in each group so that the average body weight was as close as possible. Rats were fasted with free access to water for over sixteen hours prior to the test. The rats were dosed orally (1 mL) with compounds suspended in vehicle containing 0.5% methylcellulose and 0.025% surfactant, or with vehicle alone. One hour later a subplantar injection of 0.1 mL of 1% solution of carrageenan/sterile 0.9% saline was administered and the volume of the injected foot was measured with a displacement plethysmometer connected to a pressure transducer with a digital indicator. Three hours after the injection of the carrageenan, the volume of the foot was again measured. The average foot swelling in a group of drug-treated animals was compared with that of a group of placebo-treated animals and the percentage inhibition of edema was determined (Otterhess and Bliven, Laboratory Models for Testinq NSAIDs, in Non-steroidal Anti-Inflammatory Drugs, (J. Lombardino, ed. 1985)). The % inhibition shows the % decrease from control paw volume determined in this procedure and the data for selected compounds in this invention are summarized in Table I. ______________________________________ RAT PAW EDEMA % Inhibition @ 10 mg/kg body weight ______________________________________ Example 3   15 ______________________________________

Evaluation of COX-1 and COX-2 activity in vitro

The compounds of this invention exhibited inhibition in vitro of COX-2. The COX-2 inhibition activity of the compounds of this invention illustrated in the Examples was determined by the following methods.

a. Preparation of recombinant COX beculoviruses

Recombinant COX-1 and COX-2 were prepared as described by Gierse et al, [J. Blochem., 305, 479-84 (1995)]. A 2.0 kb fragment containing the coding region of either human or murine COX-1 or human or murine COX-2 was cloned into a BamH1 site of the baculovirus transfer vector pVL1393 (Invitrogen) to generate the baculovirus transfer vectors for COX-1 and COX-2 in a manner similar to the method of D. R. O'Reilly et al (Baculovirus Expression Vectors: A Laboratory Manual (1992)). Recombinant baculoviruses were isolatedby transfecting 4 .mu.g of baculovirus transfer vector DNA into SF9 insect cells (2.times.10.sup.8) along with 200 ng of linearized baculovirus plasmid DNA by the calcium phosphate method. See M. D. Summers and G. E. Smith, A Manual of Methods for Baculovirus Vectors and Insect Cell Culture Procedures, Texas Agric. Exp. Station Bull. 1555 (1987). Recombinant viruses were purified by three rounds of plaque purification and high titer (10.sup.7 -10.sup.8 pfu/ml) stocks of virus were prepared. For large scale production, SF9 insect cells were infected in 10 liter fermentors (0.5.times.10.sup.6 /ml) with the recombinant baculovirus stock such that the multiplicity of infection was 0.1. After 72 hours the cells were centrifuged and the cell pellet homogenized in Tris/Sucrose (50 mM: 25%, pH 8.0) containing 1% 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS). The homogenate was centrifuged at 10,000 xG for 30 minutes, and the resultant supernatant was stored at -80.degree. C. before being assayed for COX activity.

b. Assay for COX-1 ond COx-2 activity

COX activity was assayed as PGE.sub.2 formed/.mu.g protein/time using an ELISA to detect the prostaglandin released. CHAPS-solubilized insect cell membranes containing the appropriate COX enzyme were incubated in a potassium phosphate buffer (50 mM, pH 8.0) containing epinephrine, phenol, and heme with the addition of arachidonic acid (10 .mu.M). Compounds were pre-incubated with the enzyme for 10-20 minutes prior to the addition of arachidonic acid. Any reaction between the arachidonic acid and the enzyme was stopped after ten minutes at 37.degree. C./room temperature by transferring 40 .mu.l of reaction mix into 160 .mu.l ELISA buffer and 25 .mu.M indomethacin. The PGE.sub.2 formed was measured by standard ELISA technology (Cayman Chemical). Results are shown in Table II.

Assay for 5-Lipoxygenase activity

The 5-lipoxygenase (5-LO) activity of the compounds were determined by the calcium ionophore-induced Leukotriene B4 (LTB4) production in human whole blood. Venous blood was collected from healthy human donors using heparin as an anti-coagulant. Human blood samples (0.2 ml of a 1:4 dilution in RPMI 1640 medium) were incubated in 96-well culture plates for 15 minutes at 37.degree. C. with test compounds dissolved in ethanol (EtOH; final concentration <1%), or vehicle. Typically 7 concentrations of test compounds were examined in duplicate. A-23187 [Sigma] was added to the blood to a final concentration of 20 .mu.g/ml, and the mixtures were incubated for 10 minutes at 37.degree. C. The reaction was stopped by placing the samples on ice. The samples were then centrifuged at 800.times.g at 4.degree. C. for 10 minutes to pellet the cells, and the supernatants were recovered for quantitation of LTB4 by ELISA (Cayman Chemical Co.; sensitivity 3 pg/ml). IC.sub.50 's were estimated from a four parameter logistic model with two parameters fixed, the minimum (0% inhibition) and maximum (100% inhibition). The IC.sub.50 value is the concentration that produces 50% inhibition between the fixed values of the minimum and maximum. Data is reported as the mean IC.sub.50 for each compound.

The compounds of the present invention may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted to such a route, and in a dose effective for the treatment intended. The compounds and composition may, for example, be administered intravascularly, intraperitoneally, subcutaneously, intramuscularly or topically.

For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are tablets or capsules. The active ingredient may also be administered by injection as a composition wherein, for example, saline, dextrose or water may be used as a suitable carrier.

The amount of therapeutically active compound that is administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the severity of the disease, the route and frequency of administration, and the particular compound employed, and thus may vary widely. The pharmaceutical compositions may contain active ingredient in the range of about 0.1 to 2000 mg, preferably in the range of about 0.5 to 500 mg and most preferably between about 1 and 100 mg. A daily dose of about 0.01 to 100 mg/kg body weight, preferably between about 0.1 and about 50 mg/kg body weight and most preferably between about 1 to 20 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day.

In the case of psoriasis and other skin conditions, it may be preferable to apply a topical preparation of a compound of this invention to the affected area two to four times a day.

For inflammations of the eye or other external tissues, e.g., mouth and skin, the formulations are preferably applied as a topical ointment or cream containing the active ingredient(s) in a total amount of, for example, 0.075 to 30% w/w, preferably 0.2 to 20% w/w and most preferably 0.4 to 15% w/w. When formulated in an ointment, the active ingredients may be employed with either paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example at least 30% w/w of a polyhydric alcohol such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethylene glycol and mixtures thereof. The topical formulation may desirably include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethylsulfoxide and related analogs. The compounds of this invention can also be administered by a transdermal device. Preferably topical administration will be accomplished using a patch either of the reservoir and porous membrane type or of a solid matrix variety. In either case, the active agent is delivered continuously from the reservoir or microcapsules through a membrane into the active agent permeable adhesive, which is in contact with the skin or mucosa of the recipient. If the active agent is absorbed through the skin, a controlled and predetermined flow of the active agent is administered to the recipient. In the case of microcapsules, the encapsulating agent may also function as the membrane.

The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier, it may comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make-up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations. Emulsifiers and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, and sodium lauryl sulfate, among others.

The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the active compound in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus, the cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmirate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters may be used. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used.

Formulations suitable for topical administration to the eye also include eye drops wherein the active ingredients are dissolved or suspended in suitable carrier, especially an aqueous solvent for the active ingredients. The antiinflammatory active ingredients are preferably present in such formulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10% and particularly about 1.5% w/w.

For therapeutic purposes, the compounds of this invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered per os, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose. Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art.

Although this invention has been described with respect to specific embodiments, the details of these embodiments are not to be construed as limitations.
