Description:
BACKGROUND OF THE INVENTION 
     A. Field Of The Invention 
     This invention relates to novel compounds of Formula I having a 2,2-disubstituted chromanonyl (benzopyran) ring-structure which are antagonists of leukotriene D 4  (LTD 4 ) and the slow reacting substance of anaphylaxis (SRS-A). In particular, the compounds of this invention are useful as pharmaceutical agents to prevent or alleviate the symptoms associated with LTD 4 , such as allergic reactions and inflammatory conditions. 
     LTD 4  is a product of the 5-lipoxygenase pathway and is the major active constitutent of slow reacting substance of anaphylaxis (SRS-A), a potent bronchoconstrictor that is released during allergic reactions. See R. A. Lewis and K. F. Austen, Nature, 293, 103-108 (1961). When administered to humans and guinea pigs, LTD 4  causes bronchoconstriction by two mechanisms: (1) directly, by stimulating smooth muscle; and (2) indirectly, through release of thromboxin A 2  which then causes contraction of respiratory smooth muscle. Because antihistamines are ineffective in the management of asthma, SRS-A and not histamine is believed to be a mediator of the bronchoconstriction occurring during an allergic attack. LTD 4  may also be involved in other inflammatory conditions such as rheumatoid arthritis. Furthermore, LTD 4  is a potent coronary vasoconstrictor and influences contractile force in the myocardium and coronary flow rate of the isolated heart. See F. Michelassi, et al., Science 217, 841 (1982); J. A. Burke, et al., J. Pharmacol, and Exp. Thera., 221,235 (1982). 
     B. Prior Art 
     Appleton, et al., J. Med. Chem., 20, 371-379 (1977) discloses a series of chromone-2-carboxylic acids having a single substituent in the 2-position, which are antagonists of SRS-A. Specifically, sodium 7-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)-2-hydroxypropoxy]-4-oxo-8-propyl-4H-1-benzopyran-2-carboxylate (FPL 55712), appears to be the first reported specific antagonist of SRS-A and LTD 4 . 
     Miyano, et al., (U.S. Pat. No. 4,546,194) discloses substituted chromanon-2-yl alkanols and derivatives thereof which are useful as LTD 4  inhibitors. In Miyano, the LTD 4  inhibitors have two substituents at the two position of their chromane ring, one of which is alkyl. Moreover, Miyano discloses a diether at position 7 which has 4-acetyl-3-hydroxy-2-propylphenoxy as the substitutent at its terminus.

     LTD 4  acts by causing brochoconstriction in both guinea pigs and humans The bronchoconstriction has two components: (1) a direct component, wherein LTD 4  stimulates the respiratory smooth muscle to constrict; and (2) an indirect component wherein LTD 4  causes the release of thromboxane A2 which also causes the construction of respiratory smooth muscle. The compounds of this invention act by antagonizing the direct constriction of respiratory smooth muscle by LTD 4 . 
     The LTD 4  antagonistic activity of the compounds of this invention were determined by both in vivo and in vitro testing upon guinea pigs. In one in vivo assay, adult male fasted Hartly guinea pigs weighing 300-360 g were pretreated with pyrilamine and indomethacin to block the bronchoconstrictive effects of endogenous histamine and the synthesis of thromboxane A2 respectively. Compounds of the invention were administered IG (intragastrically) at approximate times prior to the IV (intravenous) administration of 2000 units of LTD 4 . Intratracheal pressure was monitored prior to and subsequent to LTD 4  administration in animals anesthetized with pentobarbital and attached to a rodent respirator. A compound was determined to antagonize the direct component of LTD 4  action on respiratory smooth muscle if the compound inhibited the intratracheal insufflation pressure increases caused by LTD 4 . The compounds of this invention were found to exhibit LTD 4  antagonistic activity at doses of 10 mg/kg. 
     One of the in vitro assays utilized to determine the LTD 4  antagonistic activity of the compounds of this invention was performed on excised guinea pig ileum (smooth muscle). In this assay, control contractions of guinea pig ileum (&#34;ileum&#34;) were incubated in a solution of LTD 4  and the number of contractions in response to the LTD 4  were determined. A solution or suspension containing a compound of this invention was substituted for the control solution and the item was allowed to incubate for 30 minutes. Thereafter, doses of LTD 4  were added and increased if necessary until contractions were obtained that are approximately equal to the control. A dose/test compound ratio was calculated from the results of each test. A concentration of the test compound was judged to be active if it produced a dose ratio that was significantly greater than that obtained in a series of blank treatment tests. Duplicate tests were conducted on each concentration of test compound. Initial screening of the compounds of this invention began at 3×10 -6  M. The compounds of the present invention were determined to exhibit LTD 4  antagonistic activity at test concentrations ranging from 3×10 -6  M to 1×10 -7  M. 
     By virtue of their activity as LTD 4  inhibitors, the compounds of Formula I are useful in treating inflammatory conditions in mammals in which LTD 4  plays a role such as psoriasis, Crohn&#39;s disease, asthmatic bronchitis, ulcerative colitis and the like. A physician or veterinarian of ordinary skill can readily determine whether a subject exhibits the inflammatory condition. The preferred utility relates to treatment of ulcerative colitis. 
     The compounds can be administered in such oral dosage forms as tablets, capsules, softgels, pills, powders, granules, elixirs, or syrups. The compounds may also be administered intravascularly, intraperitoneally, subcutaneously, intramuscularly, or topically using forms known to the pharmaceutical art. In general, the preferred form of administration is oral or in such a manner so as to localize the inhibitor. For example, for asthma, the compounds could be inhaled using an aerosol or other appropriate spray. In an inflammatory condition such as rheumatoid arthritis, the compounds could be injected directly into the affected joint. 
     For the orally administered pharmaceutical compositions and methods of the present invention the foregoing active ingredients will typically be administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as &#34;carrier&#34; materials) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, softgels, elixirs syrups, drops, and the like, and consistent with conventional pharmaceutical practices. 
     For example, for oral administration in the form of tablets or capsules, the active drug components may be combined with any oral non-toxic pharmaceutically acceptable inert carrier such as lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate mannitol, and the like, or various combination thereof. For oral administration in liquid forms, such as in softgels, elixirs, syrups, drops and the like, the active drug components may be combined with any oral non-toxic pharmaceutically acceptable inert carrier such as water, saline, ethanol, polyethylene glycol, propylene glycol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, various buffers, and the like, or various combinations thereof. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated in the mixture. Suitable binders include starch, gelatin, natural sugars, corn sweeteners, natural and synthetic gums such as acacia, sodium alginate, carboxymethylcellulose, polyethylene glycol, and waxes, or combinations thereof. Lubricants for use in these dosage forms include boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like, or combinations thereof. Disintegrators include, without limitation, starch, methylcellulose, agar, bentonite, guar gum, and the like, or combinations thereof. Sweetening and flavoring agents and preservatives can also be included where appropriate. 
     For intravascular, intraperitoneal, subcutaneous, intramuscular or aerosol administration, active drug components may be combined with a suitable carrier such as water, saline, aqueous dextrose, and the like. 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 those skilled in the art. The compounds may also be formulated using pharmacologically acceptable acid or base addition salts. Moreover, the compounds or their salts may be used in a suitable hydrated form. 
     Regardless of the route of administration selected, a non-toxic but therapeutically effective quantity of one or more compounds of this invention is employed in any treatment. The dosage regimen for preventing or treating inflammatory conditions with the compounds of this invention is selected in accordance with a variety of factors, including the type, age, weight, sex, and medical condition of the patient, the severity of the inflammatory condition, the route of administration, and the particular compound employed in the treatment. A physician or veterinarian of ordinary skill can readily determine and prescribe the effective amount of the drug required to prevent or arrest the progress of the condition. In so proceeding, the physician or veterinarian could employ relatively low doses at first and subsequently increase the dose until a maximum response is obtained. 
     The compounds of this invention are prepared by the general methods illustrated in Schemes A-E. In the discussion of these schemes, the conventional numbering of the chromane ring is employed as illustrated in Formula II below. ##STR9## 
     In charts A to E, the various compounds and intermediates can be readily modified by methods known to those skilled in the art. For example, esters can be hydrolyzed to corresponding carboxylic acids (and their respective addition salts), or converted to corresponding amides by appropriate reactions with amines, or reduced to alcohols by such reagents as lithium aluminium hydride (LiAlH 4 ). Such products and intermediates can, of course, be similarly interconverted. 
     As illustrated in Chart A, 2,4-dihydroxylacetophenones of Formula X, wherein W and Y are as defined herein, react readily with ketodiesters of Formula XI, such as dimethyl 4-oxopimelate where (n=2), to afford fused ring compounds of Formula XII or of Formulas XII and XIII depending upon reaction conditions. The preferred reaction conditions for condensation and cyclization to produce the compound of Formula XII includes heating Formulas X and XI in toluene, in the presence of a base such as pyrrolidine, with provisions for removal of the water with an apparatus such as a Dean-Stark trap. Alternatively, to produce the compounds of both Formulas XII and XIII, the condensation and cyclization is allowed to proceed overnight at room temperature in the presence of a secondary amine, such as pyrrolidine, and then at reflux for about 3-4 hours. 
     The intermediates of Formulas XII and XIII may be used in reactions in Chart B without further modification or they may be converted to related intermediates of Formulas XIV and XV by methods known to those skilled in the art. For example, hydrogenation over palladium on carbon (Pd/C) will reduce the keto function of the dihydrobenzopyran-4-ones (Formulas XII or XIII) to the corresponding --CH 2  --, producing a dihydrobenzopyran of Formula XIV. Partial hydrogenation or reduction with NaBH 4  in a polar solvent will afford the corresponding 4-hydroxy compound of Formula XV. These latter two sequences of reactions provide the means for achieving the necessary diversity in &#34;V&#34; of Formula I. 
     As illustrated in Chart B, alcohols of the formula R 1  OH (XVIa) may be alkylated to form ethers in the presence of an alkylating agent (XVIb) and a base. Preferably, the alcohol is methanol or hydroxyaryl. By &#34;hydroxyaryl&#34; is meant phenol, naphthol, 5,6,7,8-tetrahydronaphthols or substituted analogs thereof, wherein the substituents include --NH 2 , NO 2 , Cl, Br, CF 3  and lower alkyl from 1-4 carbon atoms. Preferably, the alkylating agent is a dihaloalkane of the formula X--(CH 2 ) m  --X wherein X is Br, Cl or I and m is an integer from 1-9. Especially preferred as an alkylating agent is Br--(CH 2 )m--Br. Preferred reaction conditions include reaction in dry dimethylformamide (DMF) in the presence of the anhydrous base, potassium carbonate. 
     Intermediates of Formula XVII are typically purified by column chromatography on silica gel. The further reaction of XVII with 7-hydroxybenzopyran-4-ones of Formula XII in the presence of base in polar aprotic solvents afford the diester pyranone ethers (XVIII) of this invention. Similarly, diester pyran and pyranol ethers can be afforded by reaction of XVII with pyrans of Formula XIV and pyranols of Formulas XV, respectively. Preferred reaction conditions for this ether formation include reaction in dry DMF in the presence of an anhydrous base, such as potassium carbonate. 
     Chart B further illustrates that the diesters XVIII may be hydrolyzed to the corresponding diacid salt XIX in the presence of a base. Preferably, the base is a hydroxide species having a pharmaceutically acceptable cation as disclosed herein. The preferred solvent system is aqueous alcohol, such as aqueous methanol. The resulting diacid salts XIX may be converted to the corresponding diacid species XX by acidification of XIX in an aqueous alcoholic solution. Preferred acidifying agents are the mineral acids such as HCl, H 2  SO 4 , H 3  PO 4  and the like. 
     Chart C illustrates the preparation of the compounds of Formula XVIII using a variation of the method of Chart B. The compounds of Formula XII are first reacted with dihaloalkanes of the formula, X--(CH 2 ) m  --X, preferably Br--(CH 2 ) m  --Br, in the presence of base in a polar solvent to produce an intermediate of Formula XXI. As in Chart B, the preferred conditions for ether formation include reaction in dry dimethyl formamide (DMF) in the presence of anhydrous potassium carbonate (K 2  CO 3 ). By the same general procedure for ether formation just employed in converting Formula XII to XXI above, Formulas XXI and X react in the presence of base in a polar solvent to form the title compounds of this invention, Formula XVIII. 
     Chart D illustrates a condensation reaction analogous to Chart A wherein 2,4-dihydroxyacetophenones of Formula X react with ketodienes of Formula XXX in the presence of a weak base in a nonpolar solvent with heat to afford the corresponding 2,2-bis-enylpyranones of Formula XXXI. Preferred reaction conditions include toluene as the solvent and pyrrolidine as the weak base. Formula XXXI reacts with a halide XVII in a polar solvent, preferably dimethylformamide (DMF), in the presence of a base, preferably K 2  CO 3 , via a nucleophilic substitution to form the corresponding bis-(enyl)ether XXXII. The enyl groups of XXXII are oxidized to the vicinal diols of XXXIII by OsO 4  in aqueous alcoholic tetrahydrofuran (THF) in the presence of N-methylmorpholine-N-oxide. Preferably the alcoholic portion of the solvent is t-butanol. 
     Chart E illustrates further reactions of the bis-diol XXXIII to yield the compounds of this invention. The bis-diol XXXIII may be esterified to a tetraester XXXIV by acetylation--reaction of the bis-diol with an excess of an alkyl or aryl anhydride such as acetic anhydride in the presence of a weak base, preferably pyridine. Alternatively the bis-diol XXXIII can be oxidized to a bis-aldehyde, wherein the oxidized side chain loses one carbon atom. The preferred oxidizing agent is periodate (IO 4  -) associated with either H+ or an alkali metal cation. 
     In another reaction sequence in Chart E, the diester XVIII is first converted to the diacyl chloride by reaction with thionyl chloride (SO 2  Cl) and then to the bis-(dibenzyl ester) XXXVI by reaction of the diacyl chloride with 1,3-dibenzyloxy-2-propanol. Partial hydrogenation of XXXVI over 10% Pd/C produces the tetra-ol XXXVII. Alternatively, the diester XVIII may be converted to the terminal bis-(diol ester) XXXVIII by reaction with glicidol in the presence of benzyl-trimethylammonium hydroxide. 
     It is recognized that certain compounds of this invention may exist in L, D and D, L forms. These stereoisomers may be separated into their individual enantiomers by techniques well known in the art, such as recrystallization and chromatography of their optically active derivatives. 
    
    
     The following examples are given by way of illustration only and should not be construed as limiting this invention either in spirit or in scope, as based upon the disclosure herein many variations will become obvious to those of ordinary skill in the art. ##STR10##
