Description: NAPHTHALENEPROPIONIC ACID DERIVATIVES AS ANTI-TNFLAMMATORY / ANTIALLERGIC AGENTS This invention relates to novel naphthalenepropionic acid derivatives possessing lipoxygenase inhibitory and leukotriene antagonist activity, which are useful as anti-inflammatory, antiallergic and cytoprotective agents. It is known that arachidonic acid (AA) is metabolized in mammals by two distinct pathways. The metabolism of arachidonic acid by cyclooxygenase enzymes results in the production of prostaglandins and thromboxanes. The physiological activity of the prostaglandins has already been amply elucidated in recent years. The other pathway of A A metabolism involves lipoxygenase enzymes and results in the production of a number of oxidative products called leukotrienes. The latter are designated by the LT nomenclature system, and the most significant products of the lipoxygenase metabolic pathway are the leukotrienes B4, C4, D4 and E4. The substance denominated slow-reacting substance of anaphylaxis (SRS-A) has been shown to consist of a mixture of sulfidopeptide leukotrienes, C4, D4 and E4 [see Bach et al.. J. Immun.. 215. 115-118 (1980); Biochem. Biophvs. Res. Commun.. 93. 1121-1126 (1980)]. The significance of these leukotrienes is that a great deal of evidence has been accumulated showing that leukotrienes participate in inflammatory reactions, exhibit chemotactic activities, stimulate lysosomal enzyme release and act as important factors in the immediate hypersensitivity reaction. It has been shown that LTC4 and LTD4 are potent bronchoconstrictors of the human bronchi [see Dahlen et al., Nature 288. 484-486 (1980) and Piper, Int. Arch. Appl. Immunol.. 2__, suppl. 1, 41 (1985)] which stimulate the release of mucus from airways in vitro [Marom et al., Am. Rev. Resp. Pis.. 126. 449 (1982)], are potent vasodilators in skin [see Bisgaard et al., Prostaglandins. 23. 797 (1982)], and produce a wheal and flare response [Camp et al., Br. J. Pharmacol.. £Q, 497 (1983)]. The nonpeptide leukotriene, LTB4, is a powerful chemotactic factor for leukocytes [see A.S. Ford-Hutchinson, J. Rov. Soc. Med.. 74. 831-833 (1981)], which stimulates cell accumulation and affects vascular smooth muscle [see Bray, Br. Med. Bull.. 29, 249 (1983)]. The activity of leukotrienes as mediators of inflammation and hypersensitivity is extensively reviewed in Bailey and Casey, Ann. Reports Med. Chem.. 17. 203-217 (1982) and in Bray, Agents and Actions. 19, 87 (1986). There is also evidence that products of the cyclooxygenase lipoxygenase pathways play key roles in both the pathogenesis of gastric mucosal damage due to extracellular (gastric and intestinal contents, microorganisms, and the like) or intracellular (ischemia, viruses, etc.) agents, as well as in cytoprotection against such damage. Thus, on the one hand prostaglandins exert a cytoprotective effect on the gastric mucosa [see Robert, Gastroenterologv. 77, 761-767 (1979)] and this action of the prostaglandins, especially of the E series, is considered to be of importance in the treatment of gastrointestinal ulceration [see Isselbacher, Drugs. 33 (suppl.), 38-46 (198)]. On the other hand, ex vivo experiments have shown that gastric mucosal tissue from ethanol-pretreated rats is capable of LTC4 generation and that this LTC 4 production is quantitatively related to the severity of the ethanol damage [see Lange et al., Naunvn-Schmiedeberg's Arch. Pharmacol. Suppl.. 330. R27, (1985)]. It has also been demonstrated that LTC4 can induce vasoconstriction in both venous and arteriolar vessels in the rat submucosa [see Whittle, IUPHAR Ninth Int. Cong, of Pharm.. S30- 2, London, England (1984)]. This is significant since ethanol-induced lesion formation in gastric mucosa may be multifactorial with, for example, stasis of gastric blood flow contributing significantly to the development of the hemorrhagic necrotic aspects of the tissue injury [see Guth et al., Gastroenterologv, 87, 1083-90 (1984)]. Moreover, in the anesthetized cat, exogenous LTD4 evokes both increased pepsin secretion and decreased transgastric potential [Pendleton et all, Eur. J. Pharmacol.. 125. 297-99 (1986)]. A particularly significant recent finding in this regard is that 5-lipoxygenase inhibitors and some leukotriene antagonists protect the gastric mucosa against lesions ' induced by the oral or parenteral administration of most nonsteroidal antiinflammatory drugs [see Rainsford, Agents and Actions. 21. 316-19 (1987)]. Accordingly, a significant body of evidence implicates the involvement of lipoxygenase products in the development of pathological features associated with gastric mucosal lesions, such as for example those induced by ethanol exposure and administration of non-steroidal anti- inflammatory drugs. Thus, compounds which inhibit the biological effects of leukotrienes and/or which control the biosynthesis of these substances, as by inhibiting 5-lipoxygenase, are considered to be of value as cytoprotective agents. Accordingly, the biological activity of the leukotrienes and SRS's, and of lipoxygenase as the enzyme leading to the metabolism of AA to leukotrienes, indicates that a rational approach to drug therapy to prevent, remove or ameliorate the symptoms of allergies, anaphylaxis, asthma and inflammation and for gastric cytoprotection must focus on either blocking the release of mediators of these conditions or antagonizing their effects. Thus compounds, which inhibit the biological effects of the leukotrienes and SRS's and/or which control the biosynthesis of these substances, as by inhibiting lipoxygenase, are considered to be of value in treating such conditions as allergic bronchial asthma, allergic rhinitis, as well as in other immediate hypersensitivity reactions and in providing gastric cytoprotection. Our European Patent Applications 301813 and 396839 describe certain novel naphthalenepropionic acid derivatives which inhibit lipoxygenase and antagonize products of the lipoxygenase pathway, and so are useful as anti-inflammatory, anti¬ allergic and cytoprotective agents. The present invention provides further novel compounds having the following formula: wherein A is alkyl of 3-19 carbon atoms, diloweralkyl vinyl, dihalovinyl, diphenylvinyl, lower alkynyl, R V f N v I] or W is -CR 2 O- , -CH=CH- or -CH=CHCH 2 O- X is N or CR; R R R R R I I I I I Z is -C=C- , -ON- , -N=C- , -N- , -S- or -O- ; R is hydrogen or lower alkyl; R R R R OH R 1 , 1 I 1 1 I Y is -CCOR 3 , -CCH 2 OH, -CCHO, -C-N-C-NH 2 or -C-NHC-NROH I I 2 I I II 2 I II R R R R O R O * CH, with the proviso that when -CCOR 3 is CHCOR 3 , R R 3 is other than OR when W is CH2O; R 1 is hydrogen, lower alkyl or phenyl; R 2 is hydrogen or lower alkyl; or R 1 and R 2 taken together form a benzene ring, optionally substituted by halo; R R 3 is -OR , -N-OR or -NHSO 2 R 4 ; R 4 is phenyl or loweralkyl substituted phenyl; R 5 is hydrogen or halo; and the pharmaceutically acceptable salts thereof.

Some of these compounds are disclosed generally as intermediates in our European Application 301813.

The starting materials used in the reaction sequences are available commercially or can be prepared by known methods conventional in the art. Thus, for example, the benzo-fused heterocyclic compounds such as l-methyl-2-chloromethylbenzimidazole, 2-chloromethylbenzthiazole and 2- chloromethylbenzoxazole can be prepared by the following reaction schemer wherein X is O, S or NCH3. The reaction is preferably carried out at a controlled low temperature in an organic solvent, such as methylene chloride. The compounds of the invention which contain a basic nitrogen atom can form pharmacologically acceptable salts from pharmacologically acceptable organic and inorganic acids such as hydrochloric, hydrobromic, sulfonic, sulfuric, phosphoric, nitric, maleic, fumaric, benzoic, ascorbic, pamoic, succinic, methanesulfonic, acetic, propionic, tartaric, citric, lactic, malic, mandelic, cinnamic, palmitic, itaconic and benzenesulfonic. The compounds which are carboxylic acids are capable of forming alkali metal and alkaline earth carboxylates and carboxylates of pharmacologically acceptable cations derived from ammonia or a basic amine. Examples of the latter include but are not limited to cations such as ammonium, mono-, di-, and trimethylammonium, mono-, di- and triethylammonium, mono-, di- and tripropylammonium (iso and normal), ethyldimethylammonium, benzyldimethylammonium, cyclohexylammonium, benzylammonium, dibenzylammonium, piperidinium, morpholinium, pyrrolidinium, piperazinium, 1- methylpiperidinium, 4-ethylmorpholinium 1-isopropylpyrrolidinium, 1,4- dimethylpiperazinium, 1-n-butyl-piperidinium, 2-methylpiperidinium, l-ethyl-2- methylpiperidinium, mono-, di- and triethanolammonium, ethyl diethanolammonium, n-butylmonoethanolammonium, tris(hydroxymethyl)methylammonium, phenyl- monoethanolammonium, and the like. The compounds of the invention, by virtue of their ability to inhibit the activity of lipoxygenase enzyme and to antagonize mediators arising from this enzymatic pathway, are useful in the treatment of inflammatory conditions. Accordingly, the compounds are indicated in the treatment of such diseases as rheumatoid arthritis, osteoarthritis, tendinitis, bursitis and similar conditions involving inflammation. Moreover, by virtue of their ability to inhibit the activity of lipoxygenase enzyme and by their ability to antagonize the effect of LTC4, LTD4 and LTE4 which are the constituents of SRS-A, they are useful for the inhibition of symptoms induced by these leukotrienes. Accordingly, the compounds are indicated in the prevention and treatment of those disease states in which LTC4, LTD4 and LTE4 are causative factors, for example allergic rhinitis, allergic bronchial asthma and other leukotriene mediated naso-bronchial obstructive air-passageway conditions, as well as in other immediate hypersensitivity reactions, such as allergic conjunctivitis. The compounds are especially valuable in the prevention and treatment of allergic bronchial asthma. The compounds of the invention are cytoprotective agents and are considered especially useful when administered with conventional non-steroidal anti¬ inflammatory drugs, whose major side effect is gastrointestinal irritation. The cytoprotective effect of the compounds of the invention significantly reduces the gastroirritant impact of conventional anti-inflammatory drugs. This effect is based not only on the ability of the compounds of the invention to inhibit the biological effects of leukotrienes and/or control the biosynthesis of these substances, as by inhibiting lipoxygenase, but also by a shunting effect, whereby the control of the lipoxygenase pathway "shunts" the oxidation of arachidonic acid into the cyclooxygenase pathway, giving rise to an increase in the formation of cytoprotective prostaglandins. These biological effects make the compounds of the invention especially useful in treating such conditions as erosive esophagitis, inflammatory bowel disease and induced hemorrhagic lesions such as those induced by alcohol or non-steroidal anti¬ inflammatory drugs (NSAID's), hepatic ischemia, noxious agent induced damage or necrosis of hepatic, pancreatic, renal or myocardial tissue; liver parenchymal damage caused by hepatotoxic agents such as carbon tetrachloride and D-galactosamine; ischemic renal failure; disease-induced hepatic damage; bile salt-induced pancreatic or gastric damage; trauma or stress-induced cell damage; and glycerol-induced renal failure. When the compounds of the invention are employed in the treatment of allergic airway disorders, as anti-inflammatory agents and/or as cytoprotective agents, they can be formulated into oral dosage forms such as tablets, capsules and the like. The compounds can be administered alone or by combining them with conventional carriers, such as magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, low melting wax, cocoa butter and the like. Diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, tablet- disintegrating agents and the like may be employed. The compounds may be encapsulated with or without other carriers. In all cases, the proportion of active ingredients in said compositions both solid and liquid will be at least to impart the desired activity thereto on oral administration. The compounds may also be injected parenterally, in which case they are used in the form of a sterile solution containing other solutes, for example, enough saline or glucose to make the solution isotonic. For administration by inhalation or insufflation, the compounds may be formulated into an aqueous or partially aqueous solution, which can then be utilized in the form of an aerosol. The dosage requirements vary with the particular compositions employed, the route of administration, the severity of the symptoms presented and the particular subject being treated. Treatment will generally be initiated with small dosages less than the optimum dose of the compound. Thereafter the dosage is increased until the optimum effect under the circumstances is reached. In general, the compounds of the invention are most desirably administered at a concentration that will generally afford effective results without causing any harmful or deleterious side effects, and can be administered either as a single unit dose, or if desired, the dosage may be divided into convenient subunits administered at suitable times throughout the day. The lipoxygenase inhibitory and leukotriene antagonist effects as well as the antiinflammatory and cytoprotective effects of the compounds of the invention may be demonstrated by standard pharmacological procedures, which are described more fully in the examples given hereinafter. The following examples show the preparation and pharmacological testing of compounds within the invention. Examples 1 and 2 are reference examples.

Example 34 The compounds 5- and 12-hydroxyeicosatetraenoic acid (5-HETE and 12-HETE) and 5,12-dihydroxeicosatetraenoic acid (5,12-diHETE) are early arachidonic acid oxidation products in the lipoxygenase cascade which have been shown to mediate several aspects of inflammatory and allergic response. The assay of this Example measures the ability of the comounds of the invention to inhibit the synthesis of 5- HETE by rat glycogen elicited polymorphonuclear leukocytes. The assay is carried out as follows: Peritoneal PMN are obtained from female Wistar rats (150-250 g) that received an i.p. injection of 6% glycogen (10 ml). After 24 hours, rats are killed by CO2 asphyxiation and peritoneal cells are harvested by peritoneal lavage using Ca ++ and MG ++ free Hanks' balanced salt solution (HBSS). The peritoneal exudate is centrifuged at 400 g for 10 minutes. After centrifugateion, the lavaged fluid is removeed and the cell pellet is resuspended in HBSS containing Ca++ and Mg++ and 10 mM L-cysteine at a concentration of 2 x 10 7 cells/ml. To 1 ml portions of cell suspension, test drugs or vehicle are added and incubated at 37°C for 10 minutes. Following this preincubation, the calcium ionophore (10 μM), A23187, is added together with 0.5 μCi [ 14 C] arachidonic acid and further incubated for 10 minutes. The reaction is stopped by the addition of ice cold water (3 ml) and acidifying to pH 3.5. Lipoxygenase products are then extracted twice into diethyl ether. The pooled ether extracts are evaporated to dryness under nitrogen and the residue is redissolved in a small volume of methanol and spotted on aluminum backed precoated thin layer chromatographic plates. The samples are then cochromatographed with authentic reference 5-HETE in the solvent system - hexane : ether : acetic acid (50:50:3). After chromatography, the areas associated with 5-HETE standard are identified by autoradiography, cut out and quantitated by liquid scintillation. The compounds of the invention and the nonsteroidal anti-inflammatory drug naproxen, when tested in this assay at the level of 10 μM, gave the following results in inhibiting the synthesis of the arachidonic acid lipoxygenase oxidation product 5-HETE. Table 1 JCso 11.4 μM 0.43 μM * The negative value denotes a potentiation of 5-HETE synthesis. ** Tested at a level of 0.1 μM. These results show that the compounds of the invention exhibit very significant activity in inhibiting the enzyme, 5-lipoxygenase. Example 35 The procedure of Example 34 is also employed for the determination of the ability of the compounds of the invention to inhibit the synthesis of the arachidonic acid cyclooxygenase oxidation products TxB2 and PGE2. In this assay, the procedure of Example 34 is carried out as described. However, in order to determine cyclooxygenase activity, the samples are cochromatographed with authentic reference TxB 2 and PGE2 in the solvent system ethyl acetate : formic acid (80:1) and the upper phase of ethyl acetate : isooctane : acetic acid : water (110:50:20:100). After chromatography, the areas associated with the TxB 2 and PGE2 standards are identified by autoradiography, cut out and quantitated by liquid scintillation techniques. The results are calculated as in Example 34. When tested in this assay the compounds of the invention and the nonsteroidal anti-inflammatory drug naproxen, a well-established inhibitor of cyclooxygenase, at a level of 10 μM, gave the following results in inhibiting the synthesis of the arachidonic acid cyclooxygenase oxidation products TxB 2 and PGE2.

These results show that the compounds of the invention, in contradistinction to naproxen, are virtually devoid of cyclooxygenase inhibitory activity, having activity substantially only on the lipoxygenase pathway of arachidonic acid oxidation. Example 36 The assay of this Example measures the ability of the compounds tested to inhibit 5-lipoxygenase in human whole blood. This assay is carried out as follows: Blood is obtained in 50-100 ml quantities from male donors. White blood cell counts and differentials are made. Two ml of blood are placed in a 15 ml polypropylene test tube. Compounds are solubilized in dimethylsulfoxide and diluted 1:10 in 10% bovine serum albumin in phosphate buffered saline, pH 7.4 resulting in a final dimethylsulfoxide concentration of 0.1% in the blood. Then, compounds are added to the blood in a shaking water bath at 37°C for 10 minutes prior to the addition of 30 μM calcium ionophore (A23187; Sigma). After ionophore administration, whole blood samples are mixed and incubated for 20 minutes at 37°C in a shaking water bath. Incubation is terminated by placing samples in an ice bath and immediately adding ethylene glycol-bis-(β-aminoethyl ether)-N,N,N',N'-tetraacetic acid (10 mM). Samples are mixed and centrifuged at 1200 x g for 15 minutes at 4°C. Preparation of samples for evaluation by RIA or ELISA is carried out by the following protocol. Plasma is removed from sample tubes, placed in 15 ml polypropylene test tubes containing 8 ml methanol, and then vortexed to precipitate protein. Samples are stored at -70°C overnight. The next day, samples are centrifuged at 200 x g for 15 minutes at 4°C to pellet the precipitate. Samples are dried in a Savant speed vac concentrator, reconstituted to original volume with ice cold RIA or ELISA buffer, and stored at -70°C until assayed. The assay for eicosanoids (LTB4, TxB2, and PGE 2 ) is performed as described by the manufacturer of the [ 3 H]-RIA kit or ELISA kit (LTB4-Amersham, TxB2 and PGE2 - Caymen Chemical). The total eicosanoid level in 2 ml of blood is calculated and reported as ng 10 6 neutrophils. Significance is determined by a one-way analysis of variance with least significant difference (LSD) comparisons to control (p < 0.05) and ICso's (μM) are determined by regression analysis (Finney, 1978). Drug effects are expressed as percent change from control values. Compounds tested in vitro are solubilized in dimethylsulfoxide and diluted 1:10 in 10% bovine serum albumin in phosphate buffer saline resulting in a final dimethylsulfoxide concentration of 0.1% in the blood. The results for compounds of the invention tested in this assay are presented in Table 9.

This assay is carried out as follows: Male Hartley guinea pigs (350-400 g) are euthanized by a blow to the head, the neck is opened and the trachea removed. The trachea is maintained in aerated physiological salt solution, cleared of connective tissue and fat and cut into rings approximately 2 mm in width (usually containing two cartilaginous segments per ring). Two pieces of silk suture are then passed through the lumen of the tracheal ring and are tied around the cartilage, one on each side of the trachealis muscle. The tracheal ring is suspended between a glass hook and a force displacement transducer in a 10 ml organ bath for measurement of isometric tension. Tissues are maintained at 37°C in aerated (95% CO_l5% CO2) physiological salt solution of the following composition: NaCl (100 mM), KH2PO4 (1.18 mM), KC1 (4.74 mM), CaCl 2 (2.5 mM), MgSO 4 • 7H 2 O (1.19 mM), NaHCO3 (25 mM), dextrose (11.1 mM) and indomethacin (1 μM). The tracheal rings are maintained at 2 g resting tension and equilibrated for 45 minutes (with frequent washing and readjustment of resting tension). The tracheal rings are first contracted by the addition of carbachol (3 lO" 6 M), to determine tissue responsiveness and establish a reference contraction. On attainment of a stable level of contraction (approximately 30 minutes), the tissues are washed several times until baseline tension has been restored and then re-equilibrated for 30 minutes. The tissues are then incubated for 45 minutes with a test antagonist (either lxlO^M or lxlO _5 M) or 10 μl of an appropriate solvent control (control, non-treated). One tissue in each group serves as the control. Twenty minutes prior to the construction of the LTD4 cumulative concentration-response curve, L-cysteine (lxlO _2 M final bath concentration) is added to inhibit biocσnversion of LTD4 to LTE4. Only one LTD 4 concentration-response curve is constructed in each tissue. All responses to LTD4 in an individual tissue are measured as a percentage of the reference contraction of that tissue to carbachol. LTD 4 antagonist activity is determined by comparison of the concentration response curves of LTD 4 in the presence and absence of antagonist. Assessment of the relative rightward shift of the antagonist treated curve relative to the solvent (control) treated tissue is calculated as a concentration ratio (Eq. A) and used in subsequent calculations to derive an antagonist pKβ value (Eqs B and C). In the event that the maximum response to LTD4 is depressed, the EC50 for that particular curve is determined, an "apparent" pKβ reported, and the compound reported as "not-competitive." EC 50 treated tissue A) Concentration Ratio (CR) = EC 50 control C) -log K B = pK B If a compound is found to be active and/or depress the maximal response to LTD4, then a range of concentrations of the test compound should be used generating multiple concentration ratios which would then be used to perform a Schild analysis, and determination of a pA 2 value where appropriate. The activity of reference leukotriene antagonists in this assay is as follows: Compound pKn Ly-171,883 7.44 + 0.12 Wy-48,252 6.90 + 0.23 When tested in this assay, a compound of the invention gave the following results: Table 4 The above results demonstrate that the compound tested has significant leukotriene antagonist activity as measured in the in vitro isolated guinea pig trachea assay.
