Enolamides, pharmaceutical compositions and methods of use thereof for treating inflammation
This is a divisional application of U.S. Ser. No. 782,623, filed Oct. 1, 1985, now abandoned. 
    
    
     BACKGROUND ON THE INVENTION 
     The present invention relates to novel compounds, pharmaceutical compositions, and methods of use for the treatment of diseases in which products of lipoxygenase enzyme activity or the action of leukotrienes contribute to the pathological condition. The novel compounds of the present invention have activity useful for treating asthma, allergies, cardiovascular diseases, migraines, and immunoinflammatory conditions. Selected novel intermediates are also the present invention. 
     More particularly, this invention concerns certain novel enolamides having the Formula I as defined below, pharmaceutical compositions having the novel enolamides therein, and methods of use therefor in the treatment or amelioration of diseases in which products of lipoxygenase enzyme activity or the reaction of leukotrienes contribute to the pathological condition. That is, the novel enolamides inhibit lipoxygenase and/or bind leukotriene receptors. Lipoxygenase enzymes are well known in the arachidonic acid cascade. 
     Arachidonic acid serves as the biological precursor for a family of physiologically active eicosanoids. These include products derived from the action of cyclooxygenase such as the class of prostaglandin-E and -F compounds, thromboxanes, and prostacyclin, and products derived from the action of lipoxygenase enzymes such as hydroxy- and hydroperoxyeicosatetraenoic acids and the leukotrienes. 
     Lipoxygenase pathway products such as the leukotrienes B4, C4, D4, and E4, 5-hydroxyeicosatetraenoic acid, 5-hydroperoxyeicosatetraenoic acid, and 12-hydroxyeicosatetraenoic acid are related to the condition recognized as inflammation, and in allergic and immune responses. 
     These lipoxygenase products have been shown to be highly potent stereospecific inducers of polymorphonuclear leukocyte migration or chemotaxis, lysosomal enzyme release, and degranulation. Additionally, these products induce the contraction of smooth muscle such as vascular and pulmonary tissue, and induce the generation of additional inflammogens such as thromboxane A2 and prostacyclin. Lipoxygenase products also interact with vasodilator prostanoids and other mediators, leading to the enhancement or amplification of the inflammatory response. 
     Leukotrienes and the hydroxy- and hydroperoxyeicosatetraenoic acids play a major role in the pathogenesis of many disease conditions. These compounds have been found in synovial fluid of rheumatoid joints, in involved skin of psoriatic patients, in inflammed colonic tissue, and at elevated levels in ischemic myocardial tissue. They are also mediators of allergic and asthmatic conditions. 
     Compounds and pharmaceutical compositions in accordance with the present invention inhibit lipoxygenase or the biosynthesis or biochemical action of leukotrienes and, therefore, are useful in the treatment or amelioration of a number of diseases whose pathogenesis involves the production of the leukotrienes and other lipoxygenase-derived products. These lipoxygenase inhibitors aid in the prevention of tissue damage and inflammation which result from infiltration of leukocytes, release of tissuedigesting lysosomal enzymes, and changes in the permeability and contractile state of smooth muscle tissue. 
     Specific conditions in which such lipoxygenase-inhibiting or leukotriene-antagonizing compounds and pharmaceutical compositions in accordance with the present invention are useful include allergy; asthma; arthritis; skin disorders including psoriasis and acne; inflammation; inflammatory bowel diseases; pain; and cardiovasular disorders including myocardial ischemia and infarction, angina, arrhythmias, stroke, and atherosclerosis. 
     Among the novel enolamides of the present invention are benzothiopyrans and oxides thereof of Formula I having a moiety, Q, shown as substituent I 1  ; benzothiazine 1,1-dioxide type compounds having a moiety, Q, shown as substituent I 2  ; benzofurans having a moiety, Q, shown as substituent I 3  ; benzo[b]thiophenes having a moiety, Q, shown as substituent I 4  ; benzopyrans having a moiety, Q, shown as substituent I 5  ; furo[3,2-b]indoles having a moiety, Q, shown as substituent I 6  ; and indole amides having a moiety, Q, shown as substituent I 7 . Definitions for the various moieties of the present invention are found in the subsequent descriptions herein. 
     Of the above defined enolamides the compounds of Formula I wherein Q is I 1  and wherein Q is I 4  are found to have leukotriene receptor affinities also described herein as leukotriene antagonists. 
     Specific aryl carboxamides of benzothiopyran dioxides useful as antiinflammatory agents are described in British Pat. No. 1,338,996 including an aryl amide having aryl as a napthyl radical or an aryl substituted by among others alkyl, aryl, or aralkyl. Additionally, U.S. Pat. No. 3,828,073 describes phenyl carboxamides of benzothiopyrans and their corresponding S-oxides also having an antiinflammatory utility. This patent includes the phenyl having specific alkyl, aryl, and aralkyl substituents. 
     The dioxides of benzothiazines having various carboxamide moieties also useful as antiinflammatory agents are disclosed in U.S. Pat. Nos. 3,591,584; 3,674,876; 3,803,205; 3,862,319; 3,891,637; 3,892,740; 3,900,470; and 3,923,801 and also in British Pat. No. 2,118,544; Belgian Pat. No. 751,300; and Japanese No. 58225-076. Among the various carboxamides are naphthyl and substituted phenyl carboxamides including as phenyl substituents, an alkyl group.

The present invention contemplates both forms of the compounds, and the two forms are considered equivalent for purposes of the present invention. 
     The present invention is also a pharmaceutical composition comprising an effective amount of a compound having the Formula I as defined above together with a pharmaceutically acceptable carrier. An effective amount is the amount useful for treating or ameliorating a number of diseases or conditions comprising an inhibition of a lipoxygenase effect or comprising a binding of a leukotriene receptor. The diseases or conditions are readily recognized for the pathogenesis affected by the inhibitory lipoxygenase effect and affected by the binding of a leukotriene receptor, as recited herein. 
     Thus, in accordance with the present invention, another aspect of the invention, provides a method of administering to mammals, including humans, in need of treatment or amelioration of diseases or conditions an amount effective for treatment of the diseases or conditions of a compound or composition having the Formula I as defined above. The need is evident for diseases or conditions benefiting from inhibition of a lipoxygenase effect. 
     By virtue of the activity of the compounds having the Formula I of the present invention as leukotriene D4 antagonists, and inhibitors of 5-lipoxygenase and histamine release from basophils the compounds are useful in treating asthmas and allergies as well as cardiovascular disorders, migraine, and immunoinflammatory conditions.

     Additionally, the activity, of the compounds having the Formula I of the present invention is determined by the well known leukotriene receptor binding assay that is described by R. F. Bruns, W. J. Thomsen and T. A. Pugsley in Life Sciences, 33, 645 (1983) or the Herxheimer in vivo antiallergy test described in H. Herxheimer, J. Physiol. (London), Vol. 177, p. 251 (1952). 
     The antiasthma and antiallergic activity provides methods of treatment for hypersensitivity reaction having broad symptoms. For example, the symptoms may include dermatitis, lacrimation, nasal discharge, coughing, sneezing, nausea, vomiting, diarrhea, difficulty in breathing, pain, inflammation, and in severe cases, anaphylatic shock and circulatory collapse. The symptoms may be found in man as well as other animals suffering from bronchial asthma, seasonal pollinosis (e.g., hayfever), allergic rhinitis, urticoria, allergic conjunctivitis, food allergies, and anaphylactoid reactions. 
     Likewise, the activity of the compounds of Formula I provides a method of treatment for cardiovascular disorders, particularly ischemia and myocardial infarctions. The symptoms of a subject having a cardiovascular disorder may be determined by special diagnostic procedures directed to subjects having a history, general physical appearance and then detailed deviations from normal appearances suggesting a cardiovascular disorder. Such disorders are also found in man as well as other mammals. Symptoms of the disorders are described extensively in The Merck Manual 14th ed, (1982). 
     Further, method of treatment is provided by the compounds of Formula I herein for migraine and inflammation. The symptoms requiring treatment for these purposes are also readily recognized, particularly for migraine in man and/or inflammation in man as well as other mammals. 
     Pharmaceutical compositions which also are the present invention are prepared from the compound of Formula I and salts thereof described as the present invention having inert pharmaceutical carriers. The compositions may be either solid or liquid. 
     A physician or veterinarian of ordinary skill readily determines a subject who is exhibiting symptoms described herein. Regardless of the route of administration selected, the compounds of the present invention are formulated into pharmaceutically acceptable dosage forms by conventional methods known to the pharmaceutical art. 
     The compounds can be administered in such oral unit dosage forms such as tablets, capsules, pills, powders, or granules. They also may be administered rectally or vaginally in such forms as suppositories or bougies; they may also be introduced parenterally (e.g., subcutaneously, intravenously, or intramuscularly), using forms known to the pharmaceutical art. They are also introduced directly to an affected area (e.g., in the form of eye drops or by inhalation). For the treatment of asthma or allergies such as erythema, the compounds of the present invention may also be administered topically in the form of ointments, creams, gels, or the like. However, in general, the preferred route of administration is orally. 
     An effective but nontoxic quantity of the compound is employed in treatment. The ordinarily skilled physician or veterinarian will readily determine and prescribe the effective amount of the compound to prevent or arrest the progress of the condition for which treatment is administered. In so proceeding, the physician or veterinarian could employ relatively low dosages at first, subsequently increasing the dose until a maximum response is obtained. 
     Initial dosages of the compounds of the invention having Formula I are ordinarily in the area of 1 mg up to 3 g per day orally, preferably 1 mg to 500 mg per dose orally, given from one to four times daily or as needed. When other forms of administration are employed equivalent doses are administered. 
     The compounds of the invention are capable of forming both pharmaceutically acceptable acid addition and/or base salts. Base salts are formed with metals or amines, such as ammonium, alkali, and alkaline earth metals or organic amines. Examples of metals used as cations are sodium, potassium, magnesium, calcium, and the like. Examples of suitable amines are N,N&#39;dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, N-methylflucamine, and procaine. 
     Pharmaceutically acceptable acid addition salts are formed with organic and inorganic acids. 
     Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicyclic, malic, gluconic, fumaric, succinic, ascorbic, maleic, methanesulfonic, arginine, and the like. The salts are prepared by contacting the free base form with a sufficient amount of the desired acid to produce either a mono or di, etc salt in the conventional manner. The free base forms may be regenerated by treating the salt form with a base. For example, dilute solutions of aqueous base may be utilized. Dilute aqueous sodium hydroxide, potassium carbonate, ammonia, and sodium bicarbonate solutions are suitable for this purpose. The free base forms differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents, but the salts are otherwise equivalent to their respective free base forms for purposes of the invention. 
     The compounds of the invention can exist in unsolvated as well as solvated forms, including hydrated forms. In general, the solvated forms, including hydrated forms and the like are equivalent to the unsolvated forms for purposes of the invention. 
     Finally, the methods of preparation and selected novel intermediates for preparation for compounds of Formula I as defined above are also the present invention. 
     Generally, a method of preparation of the compounds of Formula I as defined above can be accomplished as shown in Scheme I wherein Q, y, R 5 , and R 6  are as defined above and R is hydrogen, lower alkyl, or phenyl. 
     When R is hydrogen the preparation of the compound of Formula I shown in Scheme I may be accomplished by reacting the acid II wherein R is hydrogen with dicyclohexylcarbodiimide or carbonyldiimidazole and the desired compound of Formula III in an inactive solvent, such as tetrahydrofuran, methylene chloride or ethylene dichloride or mixtures thereof under nitrogen at from about -10° C. to about room temperature for from 50 minutes to 24 hours. Optimum conditions vary within reasonable experimentation depending upon the reactants. 
     Alternatively, when R is lower alkyl or phenyl the preparation of the compound of Formula I shown in Scheme I may be accomplished by reacting the ester II wherein R is lower alkyl or phenyl in the presence of butyl lithium, diisopropylamine, and the desired aniline of Formula III. An inert organic solvent such as tetrahydrofuran is used in the reaction which is maintained at ice bath temperature with an ice bath for from ten minutes to two hours. See, for example, K. W. Yank, et al, Tetrahedron Letters, 1791 (1970). 
     Specific variations within the above general description may include, for example, preparation of compounds of Formula I wherein R 4  includes phenyl optionally substituted by at least one hydroxy group by treatment of corresponding methoxy groups to replace the methyl by hydrogen with boron tribromide in dichloroethane or dichloromethane, hydrobromic acid or trimethylsilyliodide using appropriate conditions. For example, see also M. V. Bhatt and S. U. Kulkarmi, Synthesis (4), 249 (1983) for a review of the cleavage of ethers. 
     The intermediates of Formula III wherein R 6  is alkyl of from six to twenty carbons, inclusive, are known or can be readily prepared by an ordinarily skilled artisan. However, the novel intermediate of Formula III wherein R 6  is --CH═CH-R 4  and --(CH 2 ) n  -R 4  or (CH 2 ) n  COR 4  are prepared by a synthetic sequence as shown for III 2 , III 3 , and III 4  in Schemes III or IV, respectively. More specifically, the compound of Formula IV 1 , wherein R 7  are the optional substituents for the phenyl as defined above for R 4 , a is an integer of from 0 to 5, and R 5  is as defined above; is prepared in a manner shown in Scheme II which is analogous to the method disclosed by P. Pfeiffer and S. Sergiewskaya, Ber., 44:1109 (1911). Subsequent reduction of compounds of Formula IV 1  is accomplished by either H 2  and Raney nickel or iron and hydrochloric acid or dithionate to produce the compound of Formula III.sub. 2 or Formula III 3 , respectively, wherein R 7  and R 5  are as defined above. The reduction is carried out in conditions within the ranges known for the reagents. Reduction of IV 1  by catalytic hydrogenation using a Raney nickel catalyst within the range of conditions known for this reduction produces compounds of Formula III 2   reducing both the nitro-moiety and unsaturation of the hydrocarbon chain in --CH═CH-R 4  of the R 6  definition with the compound of Formula I above. Reduction of IV 1  with iron and HCl or dithionate selectively reduces the nitro moiety. 
     Intermediate compounds of Formula III 4  wherein R 5  and R 7  are as defined above are obtained by catalytic addition of H 2  to the compound of Formula IV 2  over a palladium/carbon catalyst using conditions within those known or without unreasonable experimentation for hydrogenation using H 2  with these catalysts. Scheme IV shows the hydrogenation of the intermediate precursor having Formula IV 2  to obtain III 4 . The compounds of Formula IV 2  having R 5  and R 7  as defined above are prepared in a manner analogous to known Friedel-Crafts acylation methods as disclosed by Tadkod, et al, J. Karnatack Univ., 3:78-80 (1958). The Scheme IV also shows preparation of the compounds of Formula IV 2 . 
     The intermediates of Formula II wherein Q, y, and R are as defined above are synthesized by a process relative to the definitions of Q shown from (a) through (g) above. 
     For example, generally, the compounds of Formula II wherein Q is I 1  as defined above are prepared by a process shown in Scheme V. The starting material of Formula XLII 1 , wherein R 1  is as defined above, is prepared in a process analogous to the method described by L. H. Helberg and A. Juarez, in Tetrahedron Letters, 40:3553 (1974). The treatment of the material of Formula XLIIl wherein R 1  is as defined above, by dropwise addition of oxalyl chloride to the material in an organic solvent such as diethyl ether, results in the compound of Formula XXXII 1  wherein R 1  is defined above. The addition is made over a period of about 50 minutes at room temperature under nitrogen. The mixture is stirred further for from 15 hours to 24 hours. Controlled oxidation of the compound of Formula XXXII 1  with, for example, m-chloroperbenzoic acid produces compounds of Formula XXII 1  wherein R 1  is as defined above and a is one. However, the use of excess oxidizing agent, even in the case of m-chloroperbenzoic acid, produces the compound of Formula XXII 1  where R 1  is as defined above but a is equal to two. Such oxidation proceeds under nitrogen in an inert organic solvent such as dichloromethane at a temperature of about 0° C. to -10° C. preferably about 5° C. The reaction is controlled by the dropwise addition of the oxidation agent. 
     The compound of Formula XXXII 1  XXII 1 , or II 1  is subsequently reacted as shown for the compound of Formula II in Scheme I, that is, in the form of the ketolactone or as the ester thereof having the Formula XXXII 1  /XXII 1  /II 1  wherein R 1 , a, and R is as defined above. The esters of Formula II 1  are prepared by the methods analogous to those detailed by I. W. S. Still and M. T. Thomas, J. Org. Chem., 33:2730 (1968). 
     The intermediates of Formula II wherein Q is I 2  as defined above are disclosed in various references as discussed above or can be readily prepared in a manner analogous to known procedures. 
     Likewise, intermediates of Formula II wherein R 1  is as defined above, Q is I 3  wherein R is lower alkyl is known in the literature or can be readily prepared from known processes. Similarly, a compound of Formula XII 3  wherein R 1  is as defined above are known. See P. O. Corcoran, et al, J. Org. Chem., 27, p. 586 (1962) and F. Dallacker and W. Korb, Ann., 694, 98 (1966). Reactions of a compound of Formula XII 3  to prepare a compound of Formula I wherein Q is I 3  is shown in Scheme VI. The conditions of the reactions shown in Scheme VI may be analogous to those described in Wiseman, et al, J. Med. Chem., 16, p. 131 (1973). The reactant of the Formulae XIII and XXIII may be prepared from the Compound III by methods analogous to those known for the preparation of amides. 
     The intermediates of Formula II wherein R 4  is as defined above and Q is I 4  are known can be prepared by known methods when y is one or two prepared in a manner analogous to the procedure disclosed by B. Lamm and C. J. Aurell, in Acta Chemica Scand., Ser. B., p. 435 (1982) or by adding a suspension of 5-chloro-3-hydroxybenzo[b]thiophene or appropriately substituted variation in an organic solvent such as ether to a mixture prepared by adding a lower dialkyl ester of oxalic acid to a suspension of sodium methoxide in anhydrous ether all under nitrogen. Generally, the 
     temperatures of the suspensions and mixture thereof is maintained at from about -10° to about 15° C. during the mixing and subsequently stirred at room temperature for about an hour. The 5-chloro-3-hydroxybenzo[b]thiophene or appropriately substituted variation refers to a compound wherein R 1  is present and is as defined above. Such a thiophene is either known or prepared by known methods. See L. H. Werner, et al, J.A.C.S., 79, 1679 (1957) and M. S. ElShanta et al, J. Chem. Soc. (C) 2364 (1967). 
     The intermediates of Formula II wherein R is as defined above and Q is I 5  are known or can be prepared by known methods when y is one. However, these intermediates when y is two are novel and are prepared as shown in Scheme VII. R is in a ketolactone form in Scheme VII. The preparation of the compound of Formula XXII 5  wherein R 1  is as defined above is analogous to that described by L. H. Helberg and A. Zuarez. Tetrahedron Letters, 40, 3553 (1974). Oxalyl chloride is added dropwise over a period of about one-half to one hour to a suspension of the compound of Formula XXII 5  in an anhydrous organic solvent such as ether. The temperature of the suspension during addition is about room temperature. 
     The preparation of the intermediate of Formula II wherein R is as defined above and Q is I 6  is described in copending U.S. patent application Ser. No. 456,121 now issued as U.S. Pat. No. number 4,503,236 (1985). Such intermediates can be used as described above in Scheme I or can be further decarboxylated to form a compound of Formula XII 6  (see Scheme VIII) wherein R 1  and R 2  are as defined above. The decarboxylation is analogous to that discussed above in preparing an intermediate of Formula XII 3 . The compound of Formula XII 6  is subsequently reacted as shown in Scheme VIII with a compound of Formula XIII or of Formula XXIII previously described and shown as reactants in Scheme VI. Again see E. H. Wiseman, et al, J. Med. Chem., 16, 131 (1973). 
     Finally, the intermediates of Formula II wherein R is as defined above and Q is I 7  when y is one are known or readily prepared from known processes. See the disclosure by P. Friedlander and K. Kunz, Chem. Ber., 55, 1597 (1922) and A. Etiene, Bull. Soc. Chim. Fr., 15, 651 (1948) to compounds of Formula II having Q equal to I 7  wherein R 3  is hydrogen. Protection of the enolic OH is readily accomplished by known protecting groups so the reactions of Scheme I as discussed above can proceed. The compounds of Formula II having Q as I 7  wherein y is two are also generally known or can be made by known processes. See, for example, N. Buhler, et al, U.S. Pat. No. No. 4,260,544 (1981). 
     Compounds wherein X is lower alkyl can be prepared by an appropriate process step analogous to known processes. 
     Under certain circumstances it is necessary to protect either the N or O of intermediates in the above noted process with suitable protecting groups which are known. Introduction and removal of such suitable oxygen and nitrogen protecting groups are well known in the art of organic chemistry; see for example &#34;Protective Groups in Organic Chemistry,&#34; J. F. W. McOmie, ed., (New York, 1973), pages 43ff, 95ff; J. F. W. McOmie, Advances in Organic Chemistry, Vol. 3, 191-281 (1963); R. A. Borssonas, Advances in Organic Chemistry, Vol. 3, 159-190 (1963); and J. F. W. McOmie, Chem. &amp; Ind., 603 (1979). 
     Examples of suitable oxygen protecting groups are benzyl, t-butyldimethylsilyl, ethoxyethyl, and the like. Protection of an N-H containing moiety is necessary for some of the processes described herein for the preparation of compounds of this invention. Suitable nitrogen protecting groups are benzyl, triphenylmethyl, trialkylsilyl, trichloroethylcarbamate, trichloroethoxycarbonyl, vinyloxycarbamate, and the like. 
     Under certain circumstances it is necessary to protect two different oxygens with dissimilar protecting groups such that one can be selectively removed while leaving the other in place. The benzyl and t-butyldimethylsilyl groups are used in this way; either is removable in the presence of the other, benzyl being removed by catalytic hydrogenolysis, and t-butyldimethylsilyl being removed by reaction with, for example, tetra-n-butylammonium fluoride. 
     In the process described herein for the preparation of compounds of this invention the requirements for protective groups are generally well recognized by one skilled in the art of organic chemistry, and accordingly the use of appropriate protecting groups is necessarily implied by the processes of the charts herein, although not expressly illustrated. 
     The products of the reactions described herein are isolated by conventional means such as extraction, distillation, chromatography, and the like. 
     The salts of compounds of Formula I described above are prepared by reacting the appropriate base or acid with a stoichometric equivalent of the acid enol or N base compounds of Formula I, respectively, to obtain pharmacologically acceptable salts thereof.

     The usefulness of the compounds of the present invention as inhibitors of lipoxygenase enzyme or antagonists of leukotriene or other related biochemical actions is demonstrated by their effectiveness in various standard pharmacological test procedures. A description of each procedure follows. 
     Human Leukocyte Lipoxygenase Assay (LDA-H) 
     Whole blood is collected from normal volunteers and spun in a refrigerated centrifuge for four minutes at 1°-6° C. at 3800 g. The buffy coat is manually separated and washed twice with chilled 0.83% NH 4  Cl and centrifuged at 1000 RPM for ten minutes at 4° C. The white cell is suspended in culture media-EMEM supplemented with 6% Agamma human serum, tricine buffer, and neomycin and recentrifuged at 1000 g to yield a pellet containing the leukocytes used for the preparation of the acetone pentane powder. 
     The acetone-pentane powder is prepared utilizing a modification of the procedure reported for human platelet lipoxygenase. See Siegel, et al, Arachidonate Metabolism via Lipoxygenase and 12-L-hydro-peroxy-5 Eicosatetraenoic Acid Peroxidase Sensitive to Antiinflammatory Drugs, Proc. Natl. Acad. Sci., U.S.A. 77:308, 1980 and D. P. Wallach and V. R. Brown, A Novel Preparation of Human Platlet Lipoxygenase, Biochem. Biophys. Acta. 663:361, 1981. Buffy coat prepared above is resuspended in 5-7 volumes of cold 0.1M Tris buffer, pH 7.4 containing 0.154M NaCl. The suspension is centrifuged at 13,300 g for ten minutes at 4° C. The resultant pellet is retained, resuspended in five volumes of cold acetone, recentrifuged at 13,300 g and resuspended in five volumes of cold pentane. The pentane suspension is centrifuged for ten minutes at 13,300 g to give a pellet which is dried in the cold under vacuum with periodic pulverization. The dry powder is stable for several weeks when stored at -80° C. 
     Enzyme stock solution is prepared in the following manner. About 15 mg of the acetone-pentane powder is suspended in 4 ml of cold tris buffer (0.1M, pH 7.4), allowed to stand for five minutes, and homogenized thoroughly. The homogenate is sonicated three times for 15 seconds each time, diluted to 7 ml with cold tris buffer (0.1M, pH 7.4), and centrifuged at 4° C. for 60 minutes at 13,300 g. The supernatent is retained and diluted to a total of 10 ml with cold tris buffer (0.1M, pH 7.4) to give the stock enzyme solution. Additional dilutions of 2-50 fold are done as necessary to locate optimal enzyme reaction rate in the assay described below. 
     Substrate solution is prepared at 100 μM or 1.0 μM concentrations of arachidonic acid or linoleic acid in 0.1M tris buffer, pH 9.0 containing 20% ethanol. 
     The enzyme reaction is followed spectrophotometrically by the appearance of a conjugated diene product at 234 nm. The reaction is monitored at 24° C. using a Gilford Model 2600 spectrophotometer. Each assay had a total volume of 1.0 ml and contained substrate, tris buffer (0.1M, pH 9.0), 2% ethanol, and sufficient enzyme to give an easily measurable initial rate of reaction. The effects of inhibitors on the reaction are compared with control reactions run under indentical conditions. Routinely, each compounds of the present invention is incubated with the enzyme for five minutes prior to addition of substrate to initiate the reaction. Inhibition expressed as IC 50  as molar concentration of the compound required to reduce reaction rate to 50% control. 
     Binding of  3  H-Leukotriene D 4  to Guinea Pig Lung Membranes (RBL) 
     Materials 
     [14,15- 3  H]leukotriene D4 ( 3  H-LTD 4 ) (25 Ci/mmol and 40 Ci/mmol) is purchased from New England Nuclear. Unlabeled LTC 4  is a gift of Ono Pharmaceuticals (Japan). LTC 4 , LTD 4 , and LTE 4  are purchased as methyl esters from Paesel GmbH (Frankfurt, W. Germany). Concentrations of the Paesel leukotrienes are calculated from their absorbance at 280 nm. Leukotriene esters are saponified overnight under N 2  in 3.3% potassium carbonate at room temperature. Tritiated leukotrienes are stored as received from New England Nuclear at -20° C. Ono LTC 4  (5 μg/ml) is stored at -60° C. in phosphate buffer pH - 6.8. Saponified Paesel leukotrienes are stored at -60° C. in 3.3% potassium carbonate (pH 9.0-9.5). Aliquots of leukotrienes are taken from stock solutions immediately after thawing, after which the stock solutions are immediately refrozen. 2-Amino-2-(hydroxymethyl)-1,3-propanediol (Tris) is Sigma pH 7.7 pre-set crystals, and dimethylsulfoxide is Aldrich Gold Label. Preparation of crude lung membranes 
     Two pairs of lungs (1.3 g) from freshly sacrificed 300 g male guinea pigs (older animals gave substantially lower binding) from Kuiper Rabbit Farm, Gary, Ind. are disrupted with a Polytron PT 10 (setting 4) for 30 seconds in 20 ml ice-cold 50 mM Tris adjusted with HCl to pH 7.7 at 25° C. (Tris buffer), filtered through a single layer of gauze to remove connective tissue, and centrifuged at 50,000 xg for ten min. The pellet is resuspended by homogenization with a Polytron in 20 ml Tris buffer, centrifuged at 50,000 xg for ten min., resuspended, incubated at 37° C. for 30 minutes, and centrifuged again. The final pellet is resuspended in Tris buffer and either used fresh or stored at -70° C. 
     Binding assay 
     All incubations are in triplicate for 60 minutes at 25° C. in 12×75 mm polystyrene tubes containing 1 ml Tris buffer with 20 mg original tissue wet weight of guinea pig lung membranes, 0.2 nM  3  H-LTD 4  (6,000-11,000 cpm), 10 mM MgCl 2 , and 1% dimethylsulfoxide. Leukotrienes are diluted in Tris buffer. All other test compounds dissolved at 10 mM in dimethylsulfoxide on the same day as the experiment, and diluted in dimethylsulfoxide to 100× the final incubation concentration. Control incubations receive an equal volume (10 μl) of dimethylsulfoxide; the resulting concentration of dimethylsulfoxide had no effect on binding.  3  H-LTD 4  is diluted to 2 nM in Tris buffer. The membrane suspension (20 mg/0.89 ml) contains sufficient MgCl 2  to give 10 mM final concentration in the incubation. For test compounds with IC 50  values less than 1 μM, the order of incubations is test compound (10 μ l),  3  H-LTD 4  (100 μl), and values greater than 1 than 1 μM and limited water solubility, the order of additions is test compound, membranes, and  3  H-LTD 4 . All additions are performed at 0° C. Immediately after the last addition, the incubation is initiated by agitating the rack of tubes on a vortex mixer and warming to 25° C. in a water bath. Tubes are vortexed at least once more during the incubation to ensure that the membranes remained suspended. Incubations are terminated after 60 minutes by filtering under reduced pressure through 25 mm Whatman GF/B filters followed by rapid washing three times with 4 ml of ice-cold Tris buffer. Filters are added to scintillation vials with 8 ml Formula 947 (New England Nuclear), left overnight, shaken, and the radioactivity counted in a scintillation counter (efficiency 40%). Nonspecific binding, defined as binding of  3  H-LTD 4  in the presence of 100 nM LTC 4 , is 300-500 cpm for all lots of  3  H-LTD 4 . Binding to the filters in the absence of tissue is about 100 cpm, and is not affected by unlabeled LTC 4 . Specific binding, defined as total binding minus nonspecific binding, varied considerably from lot to lot of  3  H-LTD 4 . Specific  3  H-LTD 4  binding ranged from 1500 to 3000 cpm, and is greater than 80% of total binding for the better lots of  3  H-LTD 4 . 
     To Evaluate the Effect of Each Compounds as a 5-Lipoxygenase Inhibitor in Comparison to Standard Reference Agents in Human Leukocytes (5LOAl) 
     The purpose of this assay is to evaluate the activity of each compound as an inhibitor of human leukocyte 5-lipoxygenase. 
     Arachidonic acid and calcium ionophore A23l87 are obtained from Sigma (St. Louis, Mo.). Silica gel plates, GF are obtained from Analtech (Newark, Del.). Arachidonic acid, (1- 14  C) and 5-HETE ( 3  H), 5 (S)-hydroxy-6-trans, 8,11,14-cis eicosatetraenoic acid, are obtained from New England Nuclear (Boston, Mass.). Six percent Dextran-70 in 0.9% NaCl is obtained from Cutter Labs (Berkeley, Calif.). 
     Preparation of Leukocytes 
     Fresh blood from normal adult men who had not received any drugs for at least the previous five days is obtained by the Community Research Clinic (WL/PD) using venipuncture and collected into heparinized vacuotainer tubes. To every 100 ml of pooled blood is added 25 ml of dextran solution (6% dextran -70 in 0.9% sodium chloride containing 3% dextrose) and this is mixed gently in a plastic cylinder. The mixture is left to stand at room temperature for at least 90 minutes. The upper layer which is rich in leukocytes and platelets is then carefully decanted into 50 ml plastic tubes and centrifuged at about 100×g for eight minutes in an IEC centrifuge and rotor number 269 (about 600 rpm). The supernatant fluid is discarded and the pellet is resuspended in 10 ml of 0.87% ammonium chloride for exactly two minutes. This procedure is to lyse completely contaminating red blood cells. Leukocytes are then separated by centrifugation for ten minutes. The pellet is washed three times by suspension in 20 ml PBS (sodium chloride, 7.1 g; Na 2  HPO 4 , 1.15 g; KH 2  PO 4 , 0.2 g, and KCl, 0.2 g/L) and centrifuged as before. The final pellet is suspended in PBS containing 0.87 mM CaCl 2 . Viability of the cells is then checked using trypan blue exclusion method and is found to be over 90%. 
     5-Lipoxygenase Enzyme Assay 
     Leukocyte cells in suspension (0.98 ml) are incubated with or without test compounds for five minutes at 37° C. in a shaking water bath. At this time a 17 μl mixture is prepared per 1 ml of cell suspension: 100 mM arachidonic acid, 1 μl, 0.05 μCi  14  C-arachidonic acid in 5 ρl; 1 mM calcium ionophore A23187, 10 μl (1). This mixture is added and the incubation continued for five minutes. The reaction is stopped by adding four volumes of absolute ethanol and the mixture is kept in ice for 30 minutes. The floculated precipitate is separated by centrifugation at about 37,000×g for 20 minutes (Beckman Instruments rotor number 40). The alcohol extract is taken to dryness under a stream of nitrogen and the residue is dissolved in 100-200 μl absolute ethanol. At the time any turbidity is removed by centrifugation. An aliquot (25-50 μl) is applied onto 20×20 cm silica gel TLC plate and developed using the following solvent system: diethyl ether, petroleum ether (2040° C.), acetic acid (50:50: 1 v/v). Zones of 1 cm apart are scraped from the TLC plate and transferred to mini-vials. Methanol (0.5 ml) is added to dissolve the radioactivity adsorbed to the silica gel and scintillation fluid (H.P., Beckman), 5 ml is then added and vials are counted in a liquid scintillation counter. A sample of  3  H-5-HETE is applied and used for the identification of the formed 5-HETE. 
     Total radioactivity in the test as well as the control samples are normalized and the amount of 5-HETE present is calculated accordingly. 
     IC 50  values are defined as the concentrations of test agents which caused a 50% inhibition of the formation of 5-HETE as compared to control and are determined by inspection of the concentration-response curves. 
     5-Lipoxygenase Assay Using Isolated 
     Human Leukocytes (5LOA 2 ) 
     The formation of 5-HETE in human leukocytes is considered a measure of 5-lipoxygenase activity. The protocol is described in the following. 
     Fresh heparinized or EDTA treated human blood is mixed with 6% dextran-3% dextrose in isotonic saline in the ratio 0.25 ml dextran solution per 1.0 ml blood. After mixing the blood is allowed to sit at room temperature for about 90 minutes while the RBC&#39;s settle. During this period, the plasma is removed with a plastic pipette to nalgens tubes. 
     The plasma is centrifuged at 800 rpm (125 kg) on the Beckman Td-b refrigerated centrifuge to remove the platelets (which remain in the supernatant). The pellet, consisting of leukocytes and erythrocytes, is treated with 10 ml 0.87% ammonium chloride at room temperature for four minutes, lysing the red cells. At the end of four minutes the cells are diluted with a 2× volume of phosphate buffered saline, pH 7.4, and centrifuged for ten minutes. The cells are washed three times with the phosphate buffered saline. Any of the pelleted cell matter which is not easily resuspended is discarded during the washings--the material contains platelets (12-lipoxygenase activity) 
     After washing, the cells are resuspended in phosphate buffered saline containing 1.0 mM calcium and 0.5 mM magnesium. After counting the cells are diluted to 1.5-2.0×10 7  leukocytes per milliliter. 
     To each polypropylene reaction tube is added 0.48 ml leukocytes in Ca-Mg phosphate buffered saline, pH 7.4; 1-5 μl test compound buffer; or DMSO for control tubes. 
     The tubes preincubate at 37° C. for five minutes. 
     The reaction is started by adding 20 μl of the following, 0.5 μ20 mM arachidonic acid--final concentration=20 μm; 1 μ5 mM calcium ionophore A23187--final concentration=10 μm; and 18.5 μl buffer. 
     The reaction proceeds for five minutes, then is stopped by adding 0.5 ml 0.5 mM ice cold Tris buffer, pH 8.0. The tubes are chilled on ice for ten minutes and then extracted three times with a total of 3.5 ml ethyl acetate (3.0 ml removed). 
     The tubes can be stored at this point. For extended storage, the tubes should be filled with nitrogen. 
     The ethyl acetate is evaporated with a Sorvall Speed-Vac. The residue is dissolved in ethanol. The tubes can also be stored at this point at -20° C. under nitrogen. 
     A portion of the ethanol solution is injected into the HPLC system for 5-HETE quantitation. 
     The HPLC system consists of Hewlett-Packard 1040A UV spectrophotometry system with an HP85 computer. Injections are made automatically with a Waters WISP 710B. The pump is a Spectra Physics SP8700. Peaks are measured with a Hewlett Packard 3390A integrator. An RP C-18 column is used. The solvent system is isocratic; the solvent is 70% methanol and 30% 0.01M sodium acetate, pH 5.7, pumped at 1.0 ml/min. The flow is monitored at 235 nm for 5-HETE quantitation. Using a 15 cm Alltech Nucleosil C-18 5 μM column provides for a sample turnaround time of about 16 minutes. 
     IC 50  is calculated as the amount of test agent that causes 50% inhibition of the formation of 5-HETE relative to the control.

     Accordingly, the present invention also includes a pharmaceutical composition for treating one of the above diseases of conditions comprising an antidisease or anticondition effective amount of a compound of the Formula I as defined above together with a pharmaceutically acceptable carrier. 
     The present invention further includes a method for treating one of the above named diseases or conditions in mammals, including man, suffering therefrom comprising administering to such mammals either orally or parenterally a corresponding pharmaceutical composition containing a compound of Formula I as defined above in appropriate unit dosage form. 
     For preparing pharmaceutical compositions from the compounds described by this invention, inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets, and suppositories. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solublizers, lubricants, suspending agents, binders or tablet disintegrating agents; it can also be encapsulating material. In powders, the carrier is a finely divided solid which is in admixture with the finely divided active compound. In the tablet the active compound is mixed with carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from 5 or 10 to about 70 percent of the active ingredient. Suitable solid carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term &#34;preparation&#34; is intended to include the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component (with or without other carriers) is surrounded by carrier, which is thus in association with it. Similarly, cachets are included. Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration. 
     For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides or cocoa butter is first melted, and the active ingredient is dispersed homogeneously therein as by stirring. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool and thereby to solidify. 
     Liquid form preparations include solutions, suspensions, and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injection. Liquid preparations can also be formulated in solution in aqueous polyethylene glycol solution. Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavors, stabilizing and thickening agents as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, i.e., natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, and other well-known suspending agents. 
     Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions, and emulsions. These particular solid form preparations are most conveniently provided in unit dose form and as such are used to provide a single liquid dosage unit. Alternately, sufficient solid may be provided so that after conversion to liquid form, multiple individual liquid doses may be obtained by measuring predetermined volumes of the liquid form preparation as with a syringe, teaspoon, or other volumetric container. When multiple liquid doses are so prepared, it is preferred to maintain the unused portion of said liquid doses at low temperature (i.e., under refrigeration) in order to retard possible decomposition. The solid form preparations intended to be converted to liquid form may contain, in addition to the active material, flavorants, colorants, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like. The liquid utilized for preparing the liquid form preparation may be water, isotonic water, ethanol, glycerine, propylene glycol, and the like as well as mixtures thereof. Naturally, the liquid utilized will be chosen with regard to the route of administration, for example, liquid preparations containing large amounts of ethanol are not suitable for parenteral use. 
     Preferably, the pharmaceutical preparation is in unit dosage form. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, for example, packeted tablets, capsules, and powders in vials or ampoules. The unit dosage form can also be a capsule, cachet, or tablet itself or it can be the appropriate number of any of these in packaged form. 
     The quantity of active compound in a unit dose of preparation may be varied or adjusted from 1 mg to 500 mg preferably to 1 to 50 mg according to the particular application and the potency of the active ingredient. The compositions can, if desired, also contain other compatible therapeutic agents. 
     In therapeutic use as described above, the dosages may be varied depending upon the requirements of the patient, the severity of the condition being treated, and the compound being employed. Determination of the proper dosage for a particular situation is within the skill of the art. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter the dosage is increased by small increments until the optimum effect under the circumstances is reached. For convenience, the total daily dosage may be divided and administered in portions during the day if desired. ##STR1##
