Description: 5-LLPOXYGENASE INHIBITORS FIELD OF ΓNVENΠQN This invention relates to novel compounds, pharmaceutical compositions and methods for inhibiting oxygenated polyunsaturated fatty acid metabolism and disease states caused thereby. Specifically inhibited is the lipoxygenase enzyme pathway of arachidonic acid metabolism in an animal. BACKGROUND OF THE INVENTION The metabolism of arachidonic acid occurs by many pathways. One route of metabolism is via the cyclooxygenase (CO) mediated pathway which produces PGH2 which is in turn metabolized to the prostanoids (PGE2, TxA2, and prostacyclin). These products are produced by various cells including polymorphonuclear leukocytes, mast cells and monocytes. Another route is by the lipoxygenase mediated pathway which oxidizes arachidonic acid initially to 5-hydroperoxy-eicosatetraenoic acid (5-HPETE) which is further metabolized to LTA4, the precursor to the peptidoleukotrienes (LTC4, LTD4, and LTE4) and LTB4. Additionally 5-HPETE is converted to 5-hydroxyeicosatetraenoic acid (5- HETE). Lipoxygenases are classified according to the position in the arachidonic acid which is oxygenated. Platelets metabolize arachidonic acid to 12-HETE, while polymorphonuclear leukocytes (PMNs) contain 5 and 15 lipoxygenases. It is known that 12-HETE and 5,12-diHETE are chemotactic for human neutrophils and eosinophils, and may augment the inflammation process. 5-HPETE is known to be a precursor to the peptidylleukotrienes, formerly known as slow reacting substance of anaphylaxis (SRS-A) and LTB4. The SRS family of molecules, such as leukotrienes C4 and D4 have been shown to be potent bronchoconstrictors. LTB4 has been shown to be a potent chemotatic for PMNs. The products of the 5-lipoxygenase pathway are believed to play an important role in initiating and maintaining the inflammatory response of asthma, allergy, arthritis, psoriasis, and iiiflarnrnatory bowel disease. It is believed that blockage of this enzyme will interrupt the various pathways involved in these disease states and as such inhibitors should be useful in treating a variety of inflammatory diseases, such as those inumerated above. The absence of selective inhibitors of lipoxygenase, as opposed to cyclooxygenase, which are active in vivo has prevented adequate investigation of the role of leukotrienes in inflammation. The arachidonic acid oxygenated products, as noted above, have been identified as mediators of various inflammatory conditions. The various inflammatory disease states caused by these mediators and many other conditions, as discussed herein, are all conditions in which an oxygenated polyunsaturated fatty acid metabolite inhibitor, such as a 5-LO inhibitor, would be indicated. There remains a need for treatment, in this field, for compounds which are capable of inhibiting the oxygenation of arachidonic acid by inhibition of enzymes such as lipoxygenase, specifically 5-lipoxygenase (5-LO) thereby preventing the formation of various leukotrienes and prostaglandins. The compounds of Formula (I) have been found to be not only be selective 5-lipoxygenase inhibitors but also, unexpectantly, to possess analgesic activity, not normally associated with compounds having lipoxygenase inhibition.

The compounds of Formula (II) can be produced by a process which comprises A process for producing a compound of the Formula (II) as defined above, which process comprises A. reacting a compound of Formula (LTI) wherein R2 and R3 are =0; W, Ri, R7, s, q, 1, m, v, Ar, S, t, and Y are as defined for Formula (II); with hydroxylamine in solvent to yield the corresponding oxime derivative of Formula (IV) wherein R2 and R3 are =N-OH; W, Ri, R7, s, q, 1, m, v, Ar, S, t, and Y are as defined for Formula (II); which is then reduced with borane pyridine complex, borane trimethylamine, or borane tetrahydrofuran or other borane complexes, to yield the hydroxylamine derviatives of Formula (II); or B. reacting a compound of Formula (TV) as defined above with sodium cyanoborohydride or phenyldimetiiylsilane in anhydride in trifluroacetic acid to yield the hydroxylamine derviatives of Formula (II); or C. reacting a compound of Formula (V) wherein R2 and R 3 are X; X is a leaving group, such as a halogen, tosylate, mesylate or a triflate moiety; W, Ri, R7, s, q, 1, m, v, Ar, S, t, and Y are as defined for Formula (II); with Z-furfulaldehyde oxime and base to yield the corresponding nitrone of Formula (VI) which is hydroylzed to yield the corresponding hydroxylamine derviatives of Formula (II); D. reacting a compound of Formula (V) as described above, with a protected hydroxylamine to yield the corresponding protected hydroxylamine of Formula (LI); or E. wherein R2 and R3 are OH; W, Ri, R7, s, q, 1, m, v, Ar, S, t, and Y are as defined for Formula (II) as described above; with a protected hydroxylamine, such as N,O-bis(t-butyloxycarbonyl)-hydroxylamine) or bisbenzyloxycarbonyl, and triphenylphosophine/diethyldiazodicarboxylate to produce an intermediate which is treated with acid to yield the hydroxylamines of Formula (II). The homochiral compounds of Formula L), as well as the homochiral intermediates of Formula QT) can be prepared by a process which comprises A. (i) reacting a homochiral oxazolidione of Formula (A) O _J.

The compounds of Formula () can be prepared according to the following synthetic route, as displayed in Scheme I below : SCHEME I In scheme I, compound 1 or any other suitable alkoxy derivative may be treated by a known means to remove the alkyl portion of the alkoxy group, such as using a solution of sodium ethanethiolate in a solvent, such as dry DMF, to which the alkoxy derivative is added and heated. Following concentration of the reaction and addition of an organic solvent, such as ethyl acetate, an aqueous acidic workup yields the corresponding hydroxy derivative 2. The hydroxy compound 2 is then treated with a metal hydride, such as potassium hydride, and after the gas evolution subsides, a benzylhalide or phenylethyl halide, such benzylbromide, is added. After stirring and concentrating, the residue is dissolved in an organic solvent , such as ethyl acetate, and washed with acid, preferably hydrochloric, to yield after a standard aqueous workup the benzyloxy derivative 3. Compound 3 is then converted to the corresponding oxime 4 by addition of hydroxylamine hydrochloride in a solvent, such as pyridine and heated for about 30 minutes to about 2 hours. The oxime 4 is reduced to the corresponding hydroxylamine 5 by addition of a borane/pyridine complex to which is added, after stirring an acidic solution, preferably 6N HCl. Borane dimethylsulfide in tetrahydrofuran may also be used. Addition of an alkali metal hydroxide, such as NaOH, and extraction into an organic solvent , for example ethyl ether or CH2CI2, yields the hydroxylamine 5. The hydroxylamine is converted to the corresponding hydroxyurea 6 by addition of trimethysilylisocyanate and heating followed by an aqueous/organic workup. The hydroxamates can also be produced in a similar manner from the same intermediate 5 which is then converted to a diacetate intermediate by addition of an acylating agent, such as acetyl chloride (about 2 equivalents), with triethylamine (about 3 equivalents) in methylene chloride for about 30 minutes. Acetic anhydride in the presence of other bases such as pyridine will also work. The O-acetate moiety is removed by hydrolysis with an alkali metal hydroxide, such as lithium hydroxide, to yield the corresponding hydroxamic acid of Formula (L). The oxime 4 or O-protected derivatives, such as the acetate, may also be reduced by borane-trimethylamine, borane-tetrahydrofuran, sodium cyanoborohydride in methanol, or other borane compounds. Another synthetic route to prepare the compounds of Formula (I) is described in Scheme π, illustrated below. The hydroxytetralone derivative 2 is modified to contain an active leaving group, such as the triflate indicated in 7. Other acceptable leaving groups are the bromides, chlorides, iodides, tosylates, and mesylates. Using a bidentate Pd (II) catalyst, such as PdCl2 (dppf) or Pd(PPh3)4, or any other acceptable coupling agent, and a tris(phenethyl)- borane derivative, using the method of Sukuki (A. Suzuki et. al. J.A.C.S.. Il l, pgs.314- 321, 1989) results in the addition of the appropriate Ri group to yield the corresponding tetralone compound 8. The above cited procedure is especially useful for the preparation of compounds in which Ri is an alkyl group. The use of other organometallics, such as alkylzinc, -lithium, -tin or -aluminum reagents may also be useful when Ri is an alkyl group (see references cited in Suzuki paper). Additional ways of coupling using a palladium catalysis and organoborane (A. Suzuki , Pure & Appl. Chem.. 57, pgs. 1749- 1758, 1985), organozinc (R. Keenan et. al., Svn. Commun.. 19, pgs.793-798, 1989), or organotin (J. K. Stille, Angew. Chem. Int. Ed.. 25, pgs. 508-524, 1986) compounds may also be useful in this process step when Ri is an aryl or olefinic group. Also potentially useful when Ri is an alkyl, aryl, or olefinic group is the copper mediated coupling of aryl trifaltes, such as 7, using the procedure of McMurry (J. E. McMurry et. al., Tett. Lett.. 24, pgs. 2723-2726, 1983). The ketone 8 is converted to the hydroxylamine 9 by reaction with hydroxylamine, and subsequently reduced with borane in pyridine and hydrochloric acid. The hydroxylamine 9 is converted into the corresponding hydroxyurea 10 by the method outlined in Scheme I. The hydroxylamine 9 is also converted into the corresponding hydroxamate by the method outlined above for Scheme I. Alternatively, the hydroxyureas of Formula (I) wherein R4 is NR5R6 is a substituted amine or cyclic amine can be prepared by reaction of the appropriately substituted hydroxylamine hydrochloride of Formula 03) with phosgene to yield the acyl chloride intermediate which is reacted with the appropriate amine to yield the compounds of Formula (J . An additional alternative to the use of phosgene is an alkyl chloroformate, such as ethyl chloroformate, in which case the resulting R4 term of Formula Q will determine the reaction time and temperature needed for the reaction to proceed, i.e. at O° C or below or, if slow at an elevated temperatures of 100 o -200° C in the appropriate solvent. The preparation of the hydroxyureas of Formula (I) when -OB is a protecting group, as opposed to the free hydroxyl proceeds in a similiar manner. The protected hydroxylamine is reacted with phosgene or a phosgene equivalent, such as carbonyl diimidazole or phosgene trimer yielding a protected hydroxylamine intermediate which is reacted with an appropriate amine component ONHR5R6) to yield the protected hydroxyurea of Formula 0). Alternatively, the reaction of the protected hydroxylamine with trimethylsilyl isocyante or with sodium or potasium cyanate in an acidic solution as discussed above may be employed to prepare the protected hydroxyurea of Formula (T). This is followed by any means appropriate for the deprotection of the -OB group. Deprotection of the hydroxyl may be by hydrogenation with H2/Pd/C when B is benzyl , by mild acid treatment, such pyridinium para-toluenesulphonate in refluxing methanol or dilute HCl when B is tetrahydropyranyl , by a suitable base, such as potassium carbonate when B is an alkoyl or aroyl, by use of anhydrous fluoride (R4N + )F" when B is Si(Rχ)3, or by treatment with trifluoroacetic acid, trimethylsilyltrifilate with 2,6-lutidine, or anhydrous ether HCl when B is t-butyloxycarbonyl. In general, suitable protecting groups and methods for their removal will be found in T.W. Greene, Protective Groups in Organic Svnthesis. Wiley, New York, 1981. A hydroxylamine which is protected, such as 0-benzylhydroxylamine or O- tetrahydropyranyl hydroxylamine, or other O-protected hydroxylamines can also be used to produce the hydroxyureas of Formula (I) using as a starting material a compound having an active leaving group X ( in structure 11, Scheme IE replace OH with X), such as Cl, Br, OMs, or OTs by reaction with the hydroxylamine (NH2-OB) with heating in an appropriate solvent to yield a protected intermediate of Formula (II). The protected intermediate may then be deprotected using the standard removal conditions for the protecting group employed to yield the free hydroxylamines of Formula (II), or the protected intermediate may used as outlined above to prepare the O-protected hydroxyurea and then deprotected to yield the final compounds of Formula Q). Similarly, the above noted process can be used to make the starting amine compounds, chiral or not , as so desired, by use of NH3, or N3 and suitable reduction step, all well known to those skilled in the art. The starting compound, a halo compound can readily be prepared from the mesylate or toyslate derivatives (benzylic sulfonates are highly reactive and thus in most cases are used as non-isolated intermediates) or can be produced directly by a number of art known procedures from the corresponding alcohol. The mesylates or tosylate derivatives can be prepared from the ketone derivatives by reduction to the corresponding alcohol by any number of readily available agents, such as sodium borohydride, or lithium aluminum hydride. The alcohol is then reacted with mesyl or tosyl chloride in the presence of an appropriate base, for example pyridine or triethylamine, with or without additional solvent to form the mesylate or tosylate derivatives which are in turn displaced, for example either by in situ reaction or in a subsequent reaction with lithium chloride or bromide in acetone, to form the corresponding halogenated derivatives. Selected examples of protected compounds of Formula (LI) may also prepared by reaction of the alcohol 11 with a protected hydroxylamine, such as O-benzyl hydroxylamine or O-t-butyldiphenylsilyl hydroxylamine under solvolytic conditions, for example in the presence of trifluoroacetic acid. The protected intermediate may then be deprotected using the standard removal conditions for the protecting group employed to yield the free hydroxylamines of Formula 01), or the protected intermediate may be converted first to the protected urea and then to the final compounds of Formula (I) as discussed above. Another synthetic pathway which will produce the hydroxylamines of Formula (II) and may also used to prepare the optically active intermediates, if the optically active alcohol derivative is used as a starting material is illustrated in Scheme III below. The alcoholic starting material 11 is treated with N,0-bis(t-butyloxycarbonyl)hydroxylamine and triphenylphosphine / diethyldiazodicarboxylate ODEAD) producing the intermediate 12 which is then treated with an appropriate acid, such as trifluroacetic acid or hydrochloric acid, to produce the free hydroxylamines of Formula (II). The optically active alcohol 11 may be prepared by enantioselective reduction of the corresponding ketone precursor with an appropriate reducing agent (M. Kawasaki et. al., Chem. Pharm, Bull..33, pgs 52-60, 1985 or D. Mathre et. al., J. Org. Chem..56, pgs 751-762 and references cited therein). The thus obtained optically active alcohol may also be convened to the corresponding optically active halo or sulfonate compound (see D. Mathre., compounds of Formula (II). Such steps as noted above are obviously useful as well to make the racemic mixture. The alcoholic starting material 11 is treated with diphenylphosphoryl azide and triphenylphosphine /diethyldiazodicarboxylate (DEAD) producing the optically active azide which can be reduced to the optically active amine 13. SCHEME 1 1 1 Formula (II) hydroxylamine compounds An additional route for preparation of the optically active compounds of Formula (I) is detailed in Scheme IV below. The sequence starts with optically active amines, obtained through a variety of methods including the classical methods of preparing salts with chiral acids, such as camphor sulfonic acids, such techniques being readily apparent to those skilled in the art The requisite racemic amine can be prepared from the alcohol 11 or activated derivatives thereof, by the methods previously outlined above, substituting ammonia for (un)substituted hydroxylamines. One available review for resolving racemic compounds is by R.M. Secor, Chem. Rev.. 63, 197 (1963). The starting material 13 is either the pure "R" or a pure "S" configuration which is then reacted to form the intermediate 14 with 4-methoxybenzaldehdye in triethylamine. The intermediate 14 is then oxidized by a variety of agents, such as MCPBA (metachloroperbenzoic acid), MPP (monoperoxyphthalate) or MMPP (magnesium monoperoxyphthalate) to yield the oxaziridine derivative 15 which under acidic conditions then yields the hydroxylamine salt 16. The general procedure can be found in Polanski et al., Tetrahedron Letters.. 28, 2453- 2456 (1974). Alternatively, the optically active amine 13 may be converted directly to the chiral hydroxylamine 16 using dimethyldioxirane ODanishesky, et.al. J. Ore. Chem.. vol . 55, p 1981-1983, 1990) or a peracid anhydride, such as benzoyl peroxide (R.M. Coates et.al.. J. Ore. Chem.. vol. 55, 3464-3474, 1990). SCHEME IV An additional method for obtaining the homochiral hydroxyureas of formula II is to form diastereomeric adducts of the racemic hydroxyureas or hydroxamates which may then be separated by a variety of commonly used techniques, including flash chromatography and HPLC. This approach is illustrated in Scheme V. Reaction with a homochiral oxazolidinone, for example 4-(phenylmethyl)-2-όxazolidinone (see Org. Syn.. John Wiley & Sons, Inc., vol.68, p77 for preparation), with phosgene or a phosgene equivalent, such as phosgene trimer or carbonyl diimidazole, and a base in an anhydrous solvent, preferrably with NaH in toluene at reflux and then adding to this cooled solution at about -70°C to about 20 °C, preferably about -30 to about 0°C for use with phosgene. Should a phosgene equivalent be used to temperature range will be from about 20°C to about 200 °C. The thus formed intermediate, for eample, when phosgene is used, a chloro carbamate may be isolated. Additional 4-substituted chiral oxazolidinones which may also be used are optionally substituted (R groups) aryl, arylmethyl, heteroaryl, or heteroarylmethyl wherein the substituents include, but are not limited to, mono or disubstituted alkyl, halo, alkoxy, cyano, or any other protected amino, alcohol, carboxy, or sulfur (regardless of oxidation state). Additionally R can be an alkyl moiety of greater than 2 carbons, preferably longer, such as t-butyl or isopropyl, which may be optionally substituted as well. Representative examples of the aryl and heteroaryl groups include, but not limited to phenyl, naphthyl, pyrrolyl, thienyl, thiazinyl and furanyl. These oxazolidinones are prepared from the chiral amino alcohols which are readily available from reduction of the chiral amino acids by the general procedure of Evans (Org. Syn.. John Wiley & Sons, Inc. Vol. 68, p77 and references cited therein) which are incorporated by reference herein. Addition of this adduct to a solution containing the hydroxyurea in a chloronated hydrocarbon or etheral solvent, preferably CH2O2, and a base (either an amine base such as trialkylamine or pyridine or a solid alkali metal carbonate, such as potassium or calcium, but most preferably triethylamine) affords the diastereomeric adducts, 17A and 17B. Chromatography or other physical methods are employed to separate these adducts which are then cleaved under basic conditions, for example using an alkali metal hydroperoxide, such as lithium, in an-aqueous-etheral solvent (THF, glyme, digylme, ethyl ether ) at about -20 to about 50°C, preferably from about -5°C to about room temperature, more preferably from about O°C to about 15°C to yield the individual enantiomers of the hydroxyurea . 17 a- (S,S)-diastereomer 17b- (S,R)-diastereomer 1.) separate diastereomers by chromatography or recrystallization 2.) hydrolyze to yeild individual enantiomers using aqueous base (S)-isomer (R)-isomer SCHEME V For the preparation of compounds in which W contains nitrogen a synthetic sequence similar to that outlined in Scheme I is employed (illustrated in Scheme VI). The starting materials 18 shown in Scheme VI can be prepared by the method of Kano et al ( J.C.S. Perkin I. pgs 2105-2111, 1980 and references therein) or when Ri = OMe by dealkylation refunctionalization as described in previous examples (Schemes I and II). When R2 is alkyl or substituted alkyl, this group is attached by reaction of 18 using the appropriate base catalysis and alkylating reagent When R2 in the final product 20 is to be hydrogen, then protection of 18 by formation of the carbamate 19 is required (R2 = CO2R3). Following transformation to the protected hydroxyurea 20, the nitrogen is deprotected, for example with acid or fluoride when R3 is t-butyl or trimethylsilylethyl respectively. Enantiomerically pure compounds can be prepared from 19 using the procedures outlined above (Schemes III and IV plus text) or from 20 (R3 = alkyl or substituted alkyl or COR3) by resolution (Scheme V). 1 8 1 9 Ra - alkyl, substituted alkyl or CO*J 3 where R 3 is t-butyl or trimethylsilylethyl SCHEME V I Compounds in which q= 0 and 1 = 1 OFormula (I)) can be prepared by the 1,2 carbonyl transposition of the ketone intermediates used to prepare compounds in which q= 1 and 1 = 0 (Scheme VII). Many such 1,2 carbonyl transposition procedures are known (see Tetrahedron. 39, p345, 1983 for review). A particularly useful and general procedure is the reduction, dehydration, hydroboration-oxidation sequence ( see Kirkiacharian, B.S.et. al., Svnthesis. p815, 1990 for hydroboration-oxidation). When W contains nitrogen, suitable protection is required to effect this transformation. Protecting groups such as those previously outlined are applicable. When W is sulfur the oxidation of the borane to the ketone may afford sulfur oxidation products, sulfoxide or sulphones. In cases where selective reduction of the oxidized sulfur is not possible alternative routes are employed. Scheme VII Pharmaceutically acceptable base addition salts and their preparation are well known to those skilled in pharmaceuticals. Pharmaceutically acceptable bases (cations) of the compounds of Formula (J which are useful in the present invention include, but are not limited to nontoxic organic and inorganic bases, such as ammonium hydroxide, arginine, organic amines such as triethylamine, butylamine, piperazine and (rrihydroxy)methylamine, nontoxic alkali metal and alkaline earth metal bases, such as potassium, sodium and calcium hydroxides. Pharmaceutically acceptable acid addition salts of the compounds of Formula (I) which are useful in the present invention include, but are not limited to, maleate, fumarate, lactate, oxalate, methanesulfonate, ethane-sulfbnate, benzenesulfonate, tartrate, citrate, hydrochloride, hydrobromide, sulfate and phosphate salts and such salts can be readily repared by known techniques to those skilled in the art. METHOD OF TREATMENT It has now been discovered that the compounds of Formula ( ) are useful for treating disease states mediated by the 5-lipoxygenase pathway of arachidonic acid metabolism in an animal, including mammals, in need thereof. The discovery that the compounds of Formula (I) are inhibitors of the 5-lipoxygenase pathway is based on the effects of the compounds of Formula (I) on the production of 5-lipoxygenase products in blood gx vivo and on the 5- lipoxygenase in vitro assays, some of which are described hereinafter. The 5-lipoxygenase pathway inhibitory action of the compounds of Formula (£) was confirmed by showing that they impaired the production of 5-lipoxygenase products such as leukotriene B4 production by RBL-1 cell supematants. It has also been found, unexpectedly that the compounds of Formula (I) possess analgesic activity, using the phenylbenzoquinone writhing test. It has further been found that the compounds of Formula (J) do not appear to inhibit prostaglandin production in vitro and are therefore selective 5-lipoxygenase inhibitors. Test data presented in this specification is consistent with the premise that the mechanism of analgesic activity of the compounds of this invention is distinct and independent of the mechanism of action commonly associated with cyclooxygenase inhibitors. The pathophysiological role of arachidonic acid metabolites has been the focus of recent intensive studies. In addition to the well-described phlogistic activity (i.e. general inflammatory activity) of prostaglandins, the more recent description of similar activity for other eicosanoids, including the leukotrienes, has broadened the interest in these products as mediators of inflammation [See, O'Flaherty, Lab. Invest.. 47. 314-329 (1982)]. The reported discovery of potent chemotactic and algesic activity for LTB4 [see, Smith, Gen. Pharmacol.. U, 211-216 (1981) and Levine et al., Science. 225. 743-745 (1984)], together with known LTC4 and LTD4-mediated increase in capillary permeability [see, Simmons et al., Biochem. Pharmacol.. 32. 1353-1359 (1983), Vane et al., Prostaglandins. 21_, 637-647 (1981), and Camp et al., Br. J. Pharmacol.. 80, 497-502 (1983)], has led to their consideration as targets for pharmacological intervention in both the fluid and cellular phases of inflammatory diseases. The pharmacology of several inflammatory model systems has attested to the effectiveness of corticosteroids in reducing the cellular infiltration. These results, and the observation that corticosteroids inhibit the generation of both cyclooxygenase and lipoxygenase products, suggest that such dual inhibitors may effectively reduce both the fluid and cellular phases of the iriflammatory response since selective cyclooxygenase inhibitors do not reliably inhibit cell influx into inflammatory sites [See, Vinegar et al., Fed. Proc..25, 2447-2456 (1976), Higgs et al., Brit. Bull..22, 265-270 (1983), and Higgs et al., Prostaglandins. Leukotrienes and Medicine.12, 89-92 (1984)]. Under optimal conditions, it is likely that an agent with preferential lipoxygenase inhibitory activity would not share the ulcerogenic liability of cyclooxygenase inhibitors or the toxicity of corticosteroids. This may suggest that the compounds of the present invention could be useful in treating diseases, such as osteoarthritis, where it is beneficial to limit ulcerogenic activity or steroidal side effects. [See Palmoski et al., "Benoxaprofen Stimulates Proteoglycan Synthesis in Normal Canine Knee Cartiledge in Vitro." Arthritis and Rheumatism 2£, 771-774 (1983) and Rainsford, K.D., Agents and Actions 21, 316-319 (1987).] Clinical data supports the enthusiasm for inhibitors of the 5-lipoxygenase pathway in a variety of inflammatory diseases in which granulocyte and/or monocy te infiltration is prominent. The reported demonstration of elevated levels of LTB4 in rheumatoid arthritic joint fluid [See, Davidson et al., Ann. Rheum. Pis.. 42. 677-679 (1983)] also suggests a contributing role for arachidonic acid metabolites in rheumatoid arthritis. Sulfasalazine, which is used for treatment of ulcerative colitis, has been reported to inhibit LTB4 and 5-HETE production in vitro [See, Stenson et al., J. Clin. Invest.. 69, 494-497 (1982)]. The recently reported preliminary observation of efficacy, including remission, reported with sulfasalazine treatment of rheumatoid arthritic patients [See Neumann et al., Brit. Med. J.. 287. 1099-1102 (1983)] illustrates the utility of inhibitors of the 5-lipoxygenase pathway in rheumatoid arthritis. Additionally it has been reported that inflamed gastrointestinal mucosa from inflammatory bowel disease patients showed increased production of LTB4 [See, Sharon et al., Gastroenterol.. 84. 1.306 (1983)], which suggests that sulfasalazine can be effective by virtue of inhibition of production of chemotactic eicosanoids (such as the 5-Iipoxygenase pathway product known as LTB4). The observations serve to underscore utility of inhibitors of the 5-lipoxygenase pathway in inflammatory bowel disease. Another area of utility for an inhibitor of the 5-lipoxygenase pathway is in the treatment of psoriasis. It was demonstrated that involved psoriatic skin had elevated levels of LTB4 [See, Brain et al., Lancet, 19, February 19, 1983]. The promising effect of benoxaprofen on psoriasis [See, Allen et al., Brit. J. Dermatol.. 109. 126-129 (1983)], a compound with in vitro lipoxygenase inhibitory activity lends support to the concept that inhibitors of the 5-lipoxygenase pathway can be useful in the treatment of psoriasis. Lipoxygenase products have been identified in exudate fluids from gouty patients. This disorder is characterized by massive neutrophil infiltration during the acute inflammatory phases of the disease. Since a major 5-lipoxygenase product, LTB4, is produced by neutrophils, it follows that inhibition of the synthesis of LTB4 may block an amplification mechanism in gout Another area in which inhibitors of the 5-lipoxygenase product can have utility is in myocardial infarction. Studies in dogs with the dual inhibitor, BW755-C, demonstrated that the area of infarction following coronary occlusion was reduced, and such reduction was attributed to inhibition of leukocyte infiltration into the ischaemic tissue [See, Mullane et al., J. Pharmacol. Exp. Therap.. 228. 510-522 (1984)]. Yet another area in which inhibitors of lipid peroxidation involved in the OPUFA mediated can have utility is that generally refered as degenerative neurological disorders, such as Parkinson's disease. Another area is that of traumatic or ischemic injuries, such as stroke, brain or spinal cord injuries and inflammatory disease of the brain and spinal column. More specicially preferred disease states are the mycardial induced ischemic injuries and/or reperfusion injuries. [See, Braughler et al., Jour. Biol. Chem.. Vol. 262, No. 22, ppl0438-40 (1987), see also Xu et al., J. Neurochemistrv.55, 907-912 (1990); Asano et al., Molecular and Chemical Neuropathologv. lβ: 101-133 (1989) and Bracken et al., NE. J. Med., 222:1405-1411 (1990)] Yet another area of utility for inhibitors of the 5-lipoxygenase pathway is in the area of prevention of rejection of organ transplants. [See, e.g., Foegh et al., Adv. Prostaglandin. Thromboxane. and Leukotriene Research.12, 209-217 (1983).] Yet another utility for inhibitors of the 5-lipoxygenase pathway is in the treatment of tissue trauma. [See, e.g., Denzlinger et al. Science, 230 (4723), 330-332 (1985)]. Furthermore, another area of utility for inhibitors of the 5-lipoxygenase pathway is in the treatment of inflammatory reaction in the central nervous system, including multiple sclerosis. [See, e.g., Mackay et al., Clin. Exp. Immunology.15, 471-482 (1973)]. Another area of utility for inhibitors of the 5-lipoxygenase pathway is in the treatment of asthma. [See, e.g., Ford-Hutchinson, J. Allergy Clin. Immunol..24, 437-440 (1984)]. Additionally another utility for inhibitors of the 5-lipoxygense pathway is in the treatment of Adult Respitory Distress Syndrome. [ See, e.g., Pacitti et. al., Circ. Shock , 21. 155-168 (1987)]. Yet another utility for inhibitors of the 5-lipoxygenase pathway is in the treament of allergic rhinitis. Another area of utility for inhibitors of the 5-lipoxygenase pathway is in the treatment of vasculitis, glomerulonephritis, and immune complex disease. [See Kadison et al., "Vasculitis: Mechanism of Vessel Damage" in Inflammation: Basic Principles and Clinical Correlates. 703-718, Ed. Gallin et al., Raven Press, N.Y., N.Y. (1988).] Another area of utility for inhibitors of the 5-lipoxygenase pathway is in the treatment of dermatitis. [See Pye et al., "Systemic Therapy" in Textbook of Dermatology. Vol. m, 2501-2528, Ed. Rook et al., Blackwell Scientific Publications, Oxford, England (1986).] Another area of utility for inhibitors of the 5-lipoxygenase pathway is in the treatment of atherosclerosis. Recent studies have shown that inhibition of oxidative modification of low density lipoprotein slows progression of atherosclerosis, and that inhibitors of lipoxygenase effectively inhibit cell-induced oxidative modification. [See Carew et al., Proc. Natl. Acad. Sci. USA. £4. 7725-7729, November 1987; and Steinberg, P.. Cholesterol and Cardiovascular Disease. 76. 3, 508-514 (1987).] An additional area of utility for inhibitors of the 5-lipoxygenase pathway is in the opthamalogic area, in particular general inflammation of the corneal anterior and posterior segments due to disease or surgery such as in post surgical inflammation, uveitis, and allergic conjuntivitis. [See Rao N. et al. Arch. Ophathmal. 105 (3) 413-419 (1987); Chiou, L. and Chiou, G. J. Ocular Pharmacol. 1. 383-390 (1985); Bazan H., J. Ocular Pharma. 4, 43-49 (1988); and Verbey N.L. et al., Current Eve Research 2, 361-368 (1988).] FORMULATION OF PHARMACEUTICAL COMPOSITIONS The pharmaceutically effective compounds of this invention are administered in conventional dosage forms prepared by combining a compound of Formula (I) or (13) ("active ingredient") in an amount sufficient to produce 5-lipoxygenase pathway inhibiting activity with standard pharmaceutical carriers or diluents according to conventional procedures. These procedures may involve mixing, granulating and compressing or dissolving the ingredients as appropriate to the desired preparation. The pharmaceutical carrier employed may be, for example, either a solid or liquid. Exemplary of solid carriers are lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, stearic acid and the like. Exemplary of liquid carriers are syrup, peanut oil, olive oil, water and the like. Similarly, the carrier or diluent may include time delay material well known to the art, such as glyceryl monostearate or glyceryl distearate alone or with a wax. A wide variety of pharmaceutical forms can be employed. Thus, if a solid carrier is used, the preparation can be tableted, placed in a hard gelatin capsule in powder or pellet form or in the form of a troche or lozenge. The amount of solid carrier will vary widely but preferably will be from about 25 mg. to about 1 g. When a liquid carrier is used, the preparation will be in the form of a syrup, emulsion, soft gelatin capsule, sterile injectable liquid such as an ampule or nonaqueous liquid suspension. Preferably, each parenteral dosage unit will contain the active ingredient [i.e., the compound of Formula (I)] in an amount of from about 30 mg. to about 300 mg. Preferably, each oral dosage will contain the active ingredient in an amount of from about 50 mg to about 1000 mg. The compounds of Formula (J.) may also be administered topically to a mammal in need of the inhibition of the 5-lipoxygenase pathway of arachidonic acid metabolism. Thus, the compounds of Formula (I) may be administered topically in the treatment or prophylaxis of inflammation in an animal, including man and other mammals, and may be used in the relief or prophylaxis of 5-lipoxygenase pathway mediated diseases such as rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions, inflamed joints, eczema, psoriasis or other inflammatory skin conditions such as sunburn; inflammatory eye conditions including conjunctivitis; pyresis, pain and other conditions associated with inflammation. The amount of a compound of Formula (I) (hereinafter referred to as the active ingredient) required for therapeutic effect on topical administration will, of course, vary with the compound chosen, the nature and severity of the inflammatory condition and the animal undergoing treatment, and is ultimately at the discretion of the physician. A suitable anti-inflammatory dose of an active ingredient is 1.5 mg to 500 mg for topical administration, the most preferred dosage being 1 mg to 100 mg, for example 5 to 25 mg administered two or three times daily. By topical administration is meant non-systemic administration and includes the application of a compound of Formula (I) externally to the epidermis, to the buccal cavity and instillation of such a compound into the ear, eye and nose, and where the compound does not significantly enter the blood stream. By systemic administration is meant oral, intravenous, intraperitoneal and intramuscular administration. While it is possible for an active ingredient to be administered alone as the raw chemical, it is preferable to present it as a pharmaceutical formulation. The active ingredient may comprise, for topical administration, from 0.001% to 10% w/w, e.g. from 1% to 2% by weight of the formulation although it may comprise as much as 10% w/w but preferably not in excess of 5% w/w and more preferably from 0.1% to 1% w/w of the formulation. .The topical formulations of the present invention, both for veterinary and for human medical use, comprise an active ingredient together with one or more acceptable caπier(s) therefor and optionally any other therapeutic ingredient(s). The caιrier(s) must be 'acceptable' in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. Formulations suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin to the site of inflammation such as: liniments, lotions, creams, ointments or pastes, and drops suitable for administration to the eye, ear or nose. Drops according to the present invention may comprise sterile aqueous or oily solutions or suspensions and may be prepared by dissolving the active ingredient in a suitable aqueous or alcholic solution of a bactericidal and/or fungicidal agent and/or any other suitable preservative, and preferably including a surface active agent. The resulting solution may then be clarified by filtration, transferred to a suitable container which is then sealed and sterilized by autoclaving or maintaining at 98-100°C. for half an hour. Alternatively, the solution may be sterilized by filtration and transferred to the container by an aseptic technique. Examples of bactericidal and fungicidal agents suitable for inclusion in the drops are phenylmercuric nitrate or acetate (0.002%), benzalkonium chloride (0.01%) and chlorhexidine acetate (0.01%). Suitable solvents for the preparation of an oily solution include glycerol, diluted alcohol and propylene glycol. Lotions according to the present invention include those suitable for application to the skin or eye. An eye lotion may comprise a sterile aqueous solution optionally containing a bactericide and may be prepared by methods similar to those for the preparation of drops. Lotions or liniments for application to the skin may also include an agent to hasten drying and to cool the skin, such as an alcohol or acetone, and/or a moisturizer such as glycerol or an oil such as castor oil or arachis oil. Creams, ointments or pastes according to the present invention are semi- solid formulations of the active ingredient for extemal application. They may be made by mixing the active ingredient in finely-divided or powdered form, alone or in solution or suspension in an aqueous or non-aqueous fluid, with the aid of suitable machinery, with a greasy or non-greasy basis. The basis may comprise hydrocarbons such as hard, soft or liquid paraffin, glycerol, beeswax, a metallic soap; a mucilage; an oil of natural origin such as almond, com, arachis, castor or olive oil; wool fat or its derivatives, or a fatty acid such as steric or oleic acid together with an alcohol such as propylene glycol. The formulation may incorporate any suitable surface active agent such as an anionic, cationic or non-ionic sulfactant such as sorbitan esters or polyoxyethylene derivatives thereof. Suspending agents such as natural gums, cellulose derivatives or inorganic materials such as silicaceous silicas, and other ingredients such as lanolin, may also be included. The compounds of Formula (I) may also be administered by inhalation. By "inhalation" is meant intranasal and oral inhalation administration. Appropriate dosage forms for such administration, such as an aerosol formulation or a metered dose inhaler, may be prepared by conventional techniques. The daily dosage amount of a compound of Formula Q.) administered by inhalation is from about 0.1 mg to about 100 mg per day, preferably about 1 mg to about 10 mg per day. This invention relates to a method of treating a disease state which is mediated by the 5-lipoxygenase pathway in an animal in need thereof, including humans and other mammals, which comprises administering to such animal an effective, 5-lipoxygenase pathway inhibiting amount of a Formula (T) compound. This invention further relates to a method of treating analgesia in an animal in need thereof, which comprisies administering to such animal an effective, analgesia inhibiting amount of a compound of Formula (I). By the term "treating" is meant either prophylactic or therapeutic therapy. By the term "mediated" is meant caused by or exacerbated by. Such Formula (I) compound can be administered to such mammal in a conventional dosage form prepared by combining the Formula (I) compound with a conventional pharmaceutically acceptable carrier or diluent according to known techniques. It will be recognized by one of skill in the art that the form and character of the pharmaceutically acceptable carrier or diluent is dictated by the amount of active ingredient with which it is to be combined, the route of administration and other well-known variables. The Formula (J compound is administered to an animal in need of inhibition of the 5-lipoxygenase pathway in an amount sufficient to inhibit the 5- lipoxygenase pathway. The route of administration may be oral, parenteral, by inhalation or topical. The term parenteral as used herein includes intravenous, intramuscular, subcutaneous, intra-rectal, intravaginal or intraperitoneal administration. The subcutaneous and intramuscular forms of parenteral administration are generally preferred. The daily parenteral dosage regimen will preferably be from about 30 mg to about 300 mg per day. The daily oral dosage regimen will preferably be from about 100 mg to about 2000 mg per day for both 5-lipoxygenase and algesia treatment. It will be recognized by one of skill in the art that the optimal quantity and spacing of individual dosages of a Formula (I) or ( L) compound will be determined by the nature and extent of the condition being treated, the form, route and site of administration, and the particular animal being treated, and that such optimums can be determined by conventional techniques. It will also be appreciated by one of skill in the art that the optimal course of treatment, i.e., the number of doses of the Formula (I) compound given per day for a defined number of days, can be ascertained by those skilled in the art using conventional course of treatment determination tests.

The following examples further illustrate the synthesis and use of the compounds of this invention. The following examples are, therefore, to be construed as merely illustrative and not a limitation of the scope of the present invention in any way.

UTILΓΓΎ EXAMPLES I. METHODS For the in vitro experiments, compounds were dissolved at appropriate concentrations in ethanol or DMSO (dimetiiylsulfoxide) having a final concentration of less than or equal to 1.0%, and then diluted to their respective concentrations using the buffers indicated in the text. Animals: In experiments when mice were used they were CD1 mice obtained from Charles River Breeding Laboratories, and within a single experiment the mice were age- matched. Their weight range was from 25 to 42 g. The test groups generally contained 3-6 animals. 5-LLPOXYGENASE ACTIVITY: The 5-lipoxygenase (5-LO) was isolated from extracts of RBL-1 cells. The assay for assessing inhibition of the 5-LO activity was a continuous assay which monitored the consumption of oxygen (O2). The cell extract (100 ug) was preincubated with the inhibitor or its vehicle in 25 mM BisTris buffer (pH 7.0) that contained 1 mM EDTA, 1 mM ATP, 150 mM NaCl and 5% ethylene glycol for 2 minutes at 20°C (total volume 2.99 ml). Arachidonic acid (10 uM) and CaC-2 (2 mM) were added to start the reaction, and the decrease in O2 concentration followed with time using a Clark-type electrode and the Yellow Spring O2 monitor (type 53) (Yellow Springs, OH). The optimum velocity was calculated from the progress curves. All compounds were dissolved in ethanol with the final concentration of ethanol being 1% in the assay. Drag-induced effects on enzyme activities are described as the concentration of drug causing a 50% inhibition of oxygen consumption OC50). EICOS ANOID PRODUCTION FROM HUMAN MONOCYTES IN VITRO Human monocytes were prepared from leukosource packs supplied by the American Red Cross. The leukosource packs were fractionated by a two-step procedure described by F. Colatta et al. (J. Immunology 132:936, 1984) that uses sedimentation on Ficoll followed by sedimentation on Percoll. The monocyte fraction that results from this technique was composed of 80-90% monocytes with the remainder being neutrophils and lymphocytes. In addition, significant number of platelets are present. The monocytes (10^ cells) were placed into polypropylene tubes and used as a suspended culture. The assay buffer consisted of RPMI 1640 buffer, 2 mM glutamine, 2.5 mM HEPES and 2 mM CaCl2 (total volume 0.475 ml). Compounds (0.005 ml) were added in DMSO, and the cells were preincubated for 10 minutes at 37°C with constant agitation. A23187 (2 uM) was used to stimulate the cells. After an additional 10 minutes, the buffer was collected by cenrrifugation (2500 xg for 15 minutes), and stored at -70°C until assayed. LTB4 production was measured by radioimmunassay which was performed according to the manufacturer's (Advanced Magnetics, Boston, MA) instructions. PGE2 was determined using an RIA kit supplied by New England Nuclear (Boston, MA). EX VTVQ MOUSE BLOOD EICQSANQLP ASSAY Mice were pre-treated per os with vehicle or a test compound (dissolved in dimethylacetamide and diluted 1 to 10 with sesame oil) 30 minutes prior to removal of blood. The 5-lipoxygenase product LTB4, was extracted from whole blood following A23187 stimulation. Aliquots of pooled heparinized mouse blood (1 ml each aliquot) from male CDl mice (Charles River) were placed into 4 ml polypropylene tubes. The tubes were preincubated for about five minutes at 37°C. A23187 (60 uM) was added to stimulate eicosanoid production. Several aliquots of blood were not stimulated and, thus, provided background levels for eicosanoid production. All tubes were incubated for about 30 minutes at 37°C. The blood samples were centrifuged at 400 xg for about 15 minutes, and the plasma recovered for extraction. One volume of chilled acetonitrile was added to all at 5°C. The supernatants were recovered and diluted with 1% formic acid:l% triethylamine to achieve a final concentration of 20% acetonitrile. These supernatants were then loaded onto the extraction cartridge that had been conditioned according to the Manufacturer's instructions (Solid Phase Extraction Columns, J. T. Baker, C18 3 ml size). The samples were washed with 3 ml of 1% formic acid:l% triethylamine, air dried, and then washed with 3 ml of petroleum ether. After air drying again, the samples were eluted with methyl formate. The eluents were concentrated under vacuum. The concentrates were resuspended in 30% acetonitrile buffered with 50 mM ammonium acetate (200 ul). The recovery of LTB4 was 60%. The 300 ul concentrates were assayed by radioreceptor assay for LTB4 by labortatory protocol- PHENYLBENZOOUINONE-INDUCED ABPOM NAL CONSTRICTION ASSAY Phenylbenzoquinone (PBQ, Eastman Kodak Co., Rochester, NY) was dissolved in warm (50°C) ethanol and diluted with distilled water to a final concentration of 0.2 mg/ml. The solution which was protected from light by a foil wrap was administered intraperitoneally at a dose volume of 0.01 ml/gm. Mice were pre-treated with vehicle or test compound (dissolved or suspended in 25% PEG 200) for about 15 minutes and then injected with PBQ, following which each mouse was placed into individual 4 liter beakers. CP1 mice show a characteristic abdominal contraction/stretching response which consists of extending one or both of the hind limbs. These responses which occur at a variable frequency (not less than 1-2 seconds apart) were counted on a hand counter. The counting period was for 10 minutes following a 5 minute acclimation period. Results are based on the total number of constrictions observed during the 10 minute period. ATA ANALYSIS AND STATISTICS Mean values for groups were calculated and percent inhibition was determined between the vehicle control mean and test group. The ED50 was determined using linear regression analysis and was taken as the dose which resulted in a 50% inhibition of the vehicle control constriction response. Statistical analysis was done using Student's "t" test and a p<0.05 was considered statistically significant. RESULTS The effect of hydroxyurea compounds as inhibitors of 5-LO is shown in Table I. The compounds tested displayed a range of inhibitory activity both in vitro and in vivo. On the RBL-1 supernatant 5-LO enzyme assay several compounds showed activity in and around 1.0 uM IC50. A second group of compounds had activity in the range of 2-3 uM IC50 and a third group had appreciably less activity (15-48 uM IC50), which can be seen from a review of Table 1. Examination of the activity of the first two groups of compounds on human monocyte production of LTB4 corroborated the 5-LO inhibitory activity. All the compounds tested were less than 1 uM IC50. In contrast, none of the compounds showed potent inhibition of cyclooxygenase activity as indicated by production of the prostaglandin, PGE2. Evaluation of the in vivo 5-LO inhibitory activity of these compounds was done using mouse whole blood stimulated with calcium ionophore (A23187) ex vivo. As seen in Table π, with the exception of three compounds (3, 7 and 12) all of the others tested were shown to inhibit 5-LO activity ex vivo as well as in vitro. Several of these compounds also showed dose-related inhibition of LTB4 production ( ϊDso's ranged from 1-10 mg/kg, p.o.). N-Acetoxy-N-l-[6-(2-phenylethyl)-l,2,3,4-tetrahyά^onaphthyl]acetamide, showed a 64 percent inhibition of LTB4 in mouse blood ex vivo at a dose of lOmg/kg, or an IC50 of 5.8. Compounds of Formula (LI): N-l-(5-Benzyloxyindanyl)-N-hydroxy amine, N-l-(5- Benzyloxy-l,2,3,4-tetrahydronaphthyl)-N-hydroxyamine, N-l-(5-Phenoxy-l,2,3,4- tetrahydronaphthyl)-N-hydroxyamine, N- l-(5-Phenoxyindanyl)-N-hydroxyamine all inhibited LTB4 at a dose of lOmg/kg. The analgetic activity of these compounds was tested using the phenylbenzoquinone- induced abdominal constriction assay. As seen in Table π, several of these compounds (1 , 2, 5, 6,7, 8 and 10) possessed significant analgetic activity. Several of these compounds also showed a dose response QΞD507.9 to 11.2 mg/kg, p.o.). N-Acetoxy-N-l-[6-(2-phenylethyl)-l,2,3,4-tetrahydronaphthyl]-acetamide, a hydroxamate of Formula CO compounds yielded a statistically significant percent inhibition of PBQ writhing at a dose of lOmg/kg of 27%. Compounds of Formula (II): N- 1-(5- Benzyloxyindanyl)-N-hydroxyamine yielded a statistically significant percent inhibition of PBQ writhing at a dose of lOmg/kg; N-l-(5-Benzyloxy-l,2,3,4-tetrahydronaphthyl)-N- hydroxyamine, N- l-(5-Phenoxy- 1,2,3,4- tetrahydronaphthyl)-N-hydroxyamine, N- 1-(5- Phenoxyindanyl)-N-hydroxyamine, yielded a statistically significant percent inhibition of PBQ writhing at a dose of 20mg/kg. Discussion and Conclusion The compounds shown herein inhibited 5-LO enzyme activity using isolated enzyme, whole cells and mouse blood, ex vivo. This inhibition of fatty acid oxygenase activity did not extend to cyclooxygenase and therefore, these selective 5-LO inhibitors would not be expected to have analgetic activity which is a property of cyclooxygenase inhibitors (Doherty, N.S. Mediators of the Pain of Inflammation. Annual Reports in Med. Chem. 22: 245-252, 1987). It was therefore surprising to find that many of these 5-LO inhibitors had significant and potent analgetic activity. This property enhances the utility of these inhibitors in diseases such as osteoarthritis were the clinical endpoint is pain (Moskowitz, R.W. Treatment of Osteoarthritis. In: Arthritis and Allied Conditions. Ed. D.J. McCarty. Lea and Febiger, Philadelphia, PA p.1181-1189, 1979).
