2 ~ g TITLE OF THE INVENTION
UNSATURATED HYDROXYALKYLQUINOLINE ACIDS AS
LEUKOTRIENE ANTAGONISTS

BACKGROUND OF THE INVENTION
The leukotrienes constitute a group of locally acting hormones, produced in living systems from arachidonic acid. The major leukotrienes are Leukotriene B4 (LTB4), LTC4, LTD4 and LTE4. The 2S biosynthesis of these leukotrienes begins with the action of the enzyme 5-lipoxygenase on arachidonic acid to produce the epoxide known as Leukotriene A4 (LTA4), which is converted to the other leukotrienes by subsequent enzymatic steps. Further details of the biosynthesis as well as the metabolism of the leukotrienes are to be found in Leukotrienes and Lipoxygenases, ed. J. Rokach, Elsevier, Amsterdam (1989). The actions of the leukotrienes in living systems and their contribution to various diseases states are also discussed in the book by Rokach.
The art describes certain quinoline-containing compounds as having activity as antagonists of the actions of the leukotrienes.
Thus, EP 318,093 (Merck) describes compounds of structure A. Structure B is disclosed in W0 89/12629 (Rorer).

It will be understood that in the discussion of methods of treatment which follows, references to the compounds of Formula I are meant to also include the pharmaceutically acceptable salts.

Utilities The ability of the compounds of Formula I to antagonize the actions of the leukotrienes makes them useful for preventing or reversing the symptoms induced by the leukotrienes in a human subject. This antagonism of the actions of leukotrienes indicates that the compounds and pharmaceutical compositions thereof are useful to treat, prevent, or ameliorate in mammals and especially in humans: 1) pulmonary disorders including diseases such as asthma, chronic bronchitis, and related obstructive airway diseases, 2) allergies and allergic reactions such as allergic rhinitis, contact dermatitis, allergic conjunctivi-tis, and the like, 3) inflammation such as arthritis or inflammatory bowel disease, 4) pain, 5) skin disorders such as psoriasis, atopic eczema, and the like, 6) cardiovascular disorders such as angina, myocardial ischemia, hypertension, platelet aggregation and the like, 7) renal insufficiency arising from ischaemia induced by immunological or chemical (cyclosporin) etiology, 8) migraine or cluster headache, 9) ocular conditions such as uveitis, 10) hepatitis resulting from chemical, immunological or infectious stimuli, 11) trauma or 2~2a~

shock states such as burn injuries, endotoxemia and the like, 12) allograft rejection, 13) prevention of side effects associated with therapeutic administration of cytokines such as Interleukin II
and tumor necrosis factor, 14) chronic lung diseases such as cystic fibrosis, bronchitis and other small and large-airway diseases, and 15) cholecystitis.
Thus, the compounds of the present invention may also be used to treat or prevent mammalian (especially, human) disease states such as erosive gastritis; erosive esophagitis; diarrhea; cerebral spasm; premature labor; spontaneous abortion;
dysmenorrhea; ischemia; noxious agent-induced damage or necrosis of hepatic, pancreatic, renal, or myocardial tissue; liver parenchymal damage caused by hepatoxic agents such as CC14 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. The compounds also exhibit cytoprotective action.
The cytoprotective activity of a compound may be observed in both animals and man by noting the increased resistance of the gastrointestinal mucosa to the noxicus effects of strong irritants, for example, the ulcerogenic effects of aspirin or indomethacin. In addition to lessening the effect of non-steroidal anti-inflammatory drugs on the gastrointestinal tract, animal studies show that cytoprotective compounds will prevent gastric lesions induced by oral administration of strong acids, strong bases, ethanol, hypertonic saline solutions and the like.

2 ~ J ~ ~3 Two assays can be used to measure cytoprotective ability. These assays are; (A) an ethanol-induced lesion assay and (B) an indomethacin-induced ulcer assay and are described in EP 140,684.

Dose Ranges The magnitude of prophylactic or therapeutic dose of a compound of Formula I will, of course, vary with the nature of the severity of the condition to be treated and with the particular compound of Formula I and its route of administration. It will also vary according to the age, weight and response of the individual patient. In general, the daily dose range for anti-asthmatic, anti-allergic or anti-inflammatory use and generally, uses other than cytoprotection, lie within the range of from about 0.001 mg to about 100 mg per kg body weight of a mammal, preferably 0.01 mg to about 10 mg per kg, and most preferably 0.1 to 1 mg per kg, in single or divided doses. On the other hand, it may be necessary to use dosages outside these limits in some cases.
For use where a composition for intravenous administration is employed, a suitable dosage range for anti-asthmatic, anti-inflammatory or anti-allergic use is from about 0.001 mg to about 25 mg (preferably from 0.01 mg to about 1 mg) of a compound of Formula I per kg of body weight per day and for cytoprotective use from about 0.1 mg to about 100 mg (preferably from about 1 mg to about 100 mg and more preferably from about 1 mg to about 10 mg) of a compound of Formula I per kg of body weight per day.

~g~ ~?~3 In the case where an oral composition is employed, a suitable dosage range for anti-asthmatic, anti-inflammatory or anti-allergic use is, e.g. from about 0.01 mg to about 100 mg of a compound of Formula I per kg of body weight per day, preferably from about 0.1 mg to about 10 mg per kg and for cytoprotective use from 0.1 mg to about 100 mg (preferably from about 1 mg to about 100 mg and more preferably from about 10 mg to about lO0 mg) of a compound of Formula I per kg of body weight per day.
For the treatment of diseases of the eye, ophthalmic preparations for ocular administration comprising 0.001-1% by weight solutions or suspensions of the compounds of Formula I in an acceptable ophthalmic formulation may be used.
The exact amount of a compound of the Formula I to be used as a cytoprotective agent will depend on, inter alia, whether it is being administered to heal damaged cells or to avoid future damage, on the nature of the damaged cells (e.g., gastrointestinal ulcerations vs. nephrotic necrosis), and on the nature of the causative agent. An example of the use of a compound of the Formula I in avoiding future damage would be co-administration of a compound of the Formula I with a non-steroidal anti-inflam-matory drug that might otherwise cause such damage (for example, indomethacin). For such use, the compound of Formula I is administered from 30 minutes prior up to 30 minutes after administration of the NSAID. Preferably it is administered prior to or simultaneously with the NSAID, (for example, in a combination dosage form).

Pharmaceutical Compositions Any suitable route of administration may be employed for providing a mammal, especially a human - with an effective dosage of a compound of the present invention. For example, oral, rectal, topical, parenteral, ocular, pulmonary, nasal, and the like may be employed. Dosage forms include tablets, troches, dispersions, suspensions, solutions, capsules, creams, ointments, aerosols, and the like.
The pharmaceutical compositions of the present invention comprise a compound of Formula I as an active ingredient or a pharmaceutically acceptable salt thereof, and may also contain a pharmaceutically acceptable carrier and optionally other therapeutic lS ingredients. The term "pharmaceutically acceptable salts" refers to salts prepared from pharmaceutically acceptable non-toxic bases or acids including inorganic bases or acids and organic bases or acids.
The compositions include compositions suitable for oral, rectal, topical, parenteral (including subcutaneous, intramuscular, and intravenous), ocular (ophthalmic), pulmonary (nasal or buccal inhalation), or nasal administration, although the most suitable route in any given case will depend on the nature and severity of the conditions being treated and on the nature of the active ingredient. They may be conveniently presented in unit dosage form and prepared by any of the methods well-known in the art of pharmacy.

2 ~ ',, V

For administration by inhalation, the compounds of the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or nebulisers.
s The compounds may also be delivered as powders which may be formulated and the powder composition may be inhaled with the aid of an insufflation powder inhaler device. The preferred delivery system for inhalation is a metered dose inhalation (MDI) aerosol, which may be formulated as a suspension or solution of compound I in suitable propellants, such as fluorocarbons or hydrocarbons.
Suitable topical formulations of Compound I
include transdermal devices, aerosols, creams, ointments, lotions, dusting powders, and the like.
In practical use, the compounds of Formula I
can be combined as the active ingredient in intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques.
The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g., oral or parenteral (including intravenous). In preparing the compositions for oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like in the case of oral liquid preparations, such as, for example, suspensions, elixirs and solutions; or carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents and the like in the 2a~?,~.~3 case of oral solid preparations such as, for example, powders, capsules and tablets, with the solid oral preparations being preferred over the liquid preparations. Because of their ease of administration, tablets and capsules represent the most advantageous oral dosage unit form in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be coated by standard aqueous or nonaqueous techniques.
In addition to the common dosage forms set out above, the compounds of Formula I may also be administered by controlled release means and/or delivery devices such as those described in U.S.

3,598,123; 3,630,200 and 4,008,719, the disclosures of which are hereby incorporated herein by reference.
Pharmaceutical compositions of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient, as a powder or granules or as a solution or a suspension in an aqueous liquid, a non-aqueous liquid, an oil-in-water emulsion or a water-in-oil liquid emulsion. Such compositions may be prepared by any of the methods of pharmacy but all methods include the step of bringing into association the active ingredient with the carrier which constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product 2 ~ 3 into the desired presentation. For example, a tablet may be prepared by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable s machine, the active ingredient in a free-flowing form such as powder or granules, optionally mixed with a binder, lubricant, inert diluent, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine, a mixture of the powdered compound moistened with an inert liquid diluent. Desirably, each tablet contains from about 2.5 mg to about 500 mg of the active ingredient and each cachet or capsule contains from about 2.5 to about 500 mg of the active ingredient.
The following are examples of representative pharmaceutical dosage forms for the compounds of Formula I:

Injectable Suspension (I.M.) mg/ml Compound of Formula I 10 Methylcellulose 5.0 Tween 80 0.5 Benzyl alcohol 9.0 Benzalkonium chloride 1.0 Water fGr injection to a total volume of 1 ml Tablet mg/tablet Compound of Formula I 25 Microcrystalline Cellulose 415 Providone 14.0 Pregelatinized Starch 43.5 Magnesium Stearate 2.5 3~ia9 Capsule mg/capsule Compound of Formula I 25 Lactose Powder 573.5 Magnesium Stearate 1.5 Aerosol Per canister Compound of Formula I 24 mg Lecithin, NF Liquid Concentrate 1.2 mg Trichlorofluoromethane, NF 4.025 gm Dichlorodifluoromethane, NF 12.15 gm Combinations with other drugs In addition to the compounds of Formula I, the pharmaceutical compositions of the present invention can also contain other active ingredients, such as cyclooxygenase inhibitors, non-steroidal anti-inflammatory drugs (NSAIDs), peripheral analgesic agents such as zomepirac diflunisal and the like. The weight ratio of the compound of the Formula I to the second active ingredient may be varied and will depend upon the effective dose of each ingredient. Generally, an effective dose of each will be used. Thus, for example, when a compound of the Formula I is combined with an NSAID
the weight Iatio of the compound of the Formula I to the NSAID will generally range from about 1000:1 to about 1:1000, preferably about 200:1 to about 1:200.
Combinations of a compound of the Formula I and other active ingredients will generally also be within the aforementioned range, but in each case, an effective dose of each active ingredient should be used.

Methods of Synthesis Compounds of the present invention can be prepared according to the following methods.
Temperatures are in degrees Celsius.

Method A
Bromoacid II is treated with 2 equivalents of a base such as n-butyllithium in a suitable solvent such as THF at -100~C, then at -78~C to afford III, which is reacted with IV (see EP 206,751, Dec. 30, 1986; EP 318,093, May 31, 1989 and U.S.
Patent 4,851,409, July 25, 1989) to yield the hydroxyacid V. (When Y = -C_C-, compound IV can also be prepared by the methodology of Y~m~n~ka et al., Chem. Pharm. Bull., 27, 270-273 (1979) and by Crisp et al., Aust. J. Chem., 42, 279-285 (1989).) V is then esterified using conditions such as methanol/HCl, CH2N2 or MeI/K2C03 and an organometallic reagent is then added to give the diol VI. The benzylic alcohol of VI is then reacted with the thiol IX by: (1) making the chloride by reaction with methanesulfonyl chloride in the presence of triethylamine, and (2) substituting the chloride by the thiol IX in the presence of a base such as sodium hydride or cesium carbonate to afford VII. In the cases where Ql is an ester, hydrolysis with a base such as NaOH, LiOH or K2C03 (followed by acidification) affords the acid VIII. VII and VIII
are both representatives of structure I.

2 ~ J ~ ~

Method B
The ketone IV is reduced to the benzylic alcohol using a reagent such as NaB~4. This benzylic alcohol is converted to the benzylic bromide, using conditions such as carbon tetrabromide/1,2-bis-(diphenylphosphino)ethane, and treatment with triphenylphosphine affords the phosphonium salt X.
Using a base such as potassium hexamethyldisilazide, the ylid of X is formed and is added to a lactol.
Oxidation of the benzylic alcohol so obtained using conditions such as (1) MnO2 in EtOAc and (2) MnO2/HCN/MeOH affords the ester XI. The thiol IX is then added to XI using a Lewis acid such as AlC13 or TiC14 to give the thioether XII. Reaction of XII
with an organometallic compound such as a lithium or a magnesium salt, yield, in the cases where Ql is stable in these conditions, the tertiary alcohol XIII, which is a representative of structure I.

Method C
The ester XXVII, obtained by Method E, is hydrolyzed with a base such as NaOH to give XIV. XIV
is reacted with an organometallic and the reaction mixture is quenched with chlorotrimethylsilane to yield the hydroxyketone XV. The benzylic alcohol is then reacted with methanesulfonyl chloride in the presence of a base such as triethylamine. The mesylate so obtained is substituted by the thiolate derivative of IX to afford XVI. Finally, an organometallic reaction or a reduction using a reagent such as NaBH4 on XVI gives the alcohol XVIII. Using this method, two different R groups can be added to give a secondary or an unsymmetrical tertiary alcohol.

S Method D
The hydroxyacid XVII (included within the definition of XIV) is cyclized to the lactone XXI
using a reagent such as 2-chloro-N-methylpyridinium iodide. An organometallic reagent is then added to XXI to give the diol XXII. Finally, the secondary alcohol is substituted by the thiol IX as in Method C
to yield the thioether XX.

Method E
The aldehyde XXIII, a derivative of IV, is reacted with an organometallic reagent and the benzylic alcohol so obtained is oxidized to XXIV with an oxidant like activated manganese dioxide. XXIV is then reacted with the iodide XXV in the presence of a base such as lithium diisopropylamide to yield the alkylation product XXVI. Reduction with sodium borohydride or addition of an organometallic reagent afford the hydroxyester XXVII, which is then treated as the lactone XXI in Method D to give the thioether XXVIII.

Method F
The enolate of the ketone XXIX, obtained by treatment of XXIX with a base such as KH or NaH, is reacted with dimethylcarbonate to yield the ketoester XXX. XXX is enolized with a base such as NaH and treated with the iodide XXXI, the methyl ester of J ~3 ~

XXV. The adduct so obtained is then decarboxylated using conditions such as heating with HCl in acetic acid to afford a mixture of the ester XXXII and the corresponding acid. Esterification of the mixture, using a reagent such as diazomethane or methyl iodide and K2C03, yields XXXII, which is then converted to XXXIII or its epimer, as described in Method G.

Method G
The hydroxy acid XvII is esterified using conditions such as heating with MeI and K2C03 or reacting with diazomethane. Treatment of this hydroxyester with an oxidant such as activated manganese dioxide affords the ketoester XXXIV. The ketone is then reduced using the chiral oxazaborolidine XXXV in the presence of borane/THF
complex. Reaction of the ester with an organometallic gives the diol XXXVI, which is chiral XXII. Protection of the secondary alcohol with tert-butylchlorodiphenylsilane in the presence of a basesuch as 4-(dimethylamino)pyridine, protection of the tertiary alcohol as the 2-tetrahydropyranyl ether and removal of the silyl ether afford XXXVII. The chiral center of XXXVII can be inverted to give XXXVIII
using condit.ions such as: ~1) treatment with triphenylphosphine, diethyl azodicarboxylate and an acid such as R-(-)a-methoxyphenylacetic acid (chiral acid improves the resolution), and (2) hydrolysis of the ester so obtained with a base such as NaOH.
Formation of the mesylate and substitution with the thiol IX as in Method C, followed by hydrolysis of 2.

the 2-tetrahydropyranyl ether using conditions such as pyridinium p-toluenesulfonate in methanol afford the thioethers XXXIX and XL.

5 Method H
The bromoaldehyde XLI is reduced with a reagent such as sodium borohydride and the resulting benzylic alcohol is protected as the 2-tetrahydropyranyl ether. The Grignard reaction of XLII on Xv afford an hydroxyacid, which is then converted to the ketone XLIII as in Method C.
Substitution by the thiol IX is then performed (as in Method C) to afford XLIV. An organometallic reagent is then added to this ketone to yield a tertiary alcohol. In cases where Ql is an acid, it is protected as the methyl ester using a reagent such as CH2N2. Deprotection of the benzylic alcohol, followed by an oxidation with a reagent such as MnO2, affords the aldehyde XLV. A Wittig reaction with a phosphonium derivative of a substituted 2-(bromo-methyl)quinoline, followed by an hydrolysis step when Ql is an ester, yield the styrylquinoline XLVI.

Method I
The phenylacetic acid XLVII is reduced to the alcohol XLVIII using a reagent such as borane in tetrahydrofuran. Formation of the alcoholate with one equivalent of a Grignard reagent, followed by treatment with magnesium afford the dimagnesium salt of XLVIII. It is added to a ketone or an aldehyde toyield the alcohol XLIX. The bromide L is then formed using conditions such as (1) formation of the 2 ~ ~ ? 3 r ~ 3 mesylate with methanesulfonyl chloride and triethylamine and (2) substitution of the mesylate by sodium bromide in N,N-dimethyl formamide. The dimagnesium salt of L is then formed as previously described and added to the ketone IV. The adduct LI
is then reacted with the thiol IX as in Method C to yield LII.

Method J
The ketoester XXX is treated with the iodide LIII and decarboxylated as in Method F. Reduction of the ketone with a reagent such as NaBH4 yields the alcohol LIV. By reaction with an organometallic in toluene, the nitrile LIV is converted to the amine LV. The thiol IX is then added as in Method C to afford LVI. Reaction of an iodide with the amine LVI
gives a secondary or tertiary amine LVII. Both LVI
and LVII are representatives of structure I.

Method K
Vinylmagnesium bromide or alkylmagnesium bromide is added to the aldehyde derivative of IV to yield LVIII. Using the procedure of R.C. Larock et al. (Tetrahedron Letters, 30, 6629 (1989), the aryl 2s halide LIX is coupled to the alcohol LVIII to give LX. When Q- is an ester or an alcohol, LX can be converted to LXI or its epimer, a structure representative of Ia, using the procedure of Method G. Also, when Q3 is Ql, chiral reduction of the ketone LX with XXXV as in Method G followed by formation of the mesylate and substitution by the thiol LXII afords LXIII, a structure representative of Ib.

2 a ~ ~ ~

Method L
The iodide LXIV is converted to a mixed zinc copper organometallic which is added to XXIII in the presence of BF3-Et20. This alcohol LXV is converted to a mesylate and displaced with LXII in the presence of a base such as Cs2C03. Alternatively, the alcohol may be oxidized (Swern type) and reduced using catalyst such as B-chlorodiisopinocampheylborane (H.C. Brown et al., J. Am. Soc., 1988, llO, 1539) before mesylation and displacement to give LXVII or its enantiomer.

Method M
The tertiary alcohol of LX is protected first with dihydropyran (DHP) and the ketone is then reduced with (-)-B-chlorodiisopinocampheylborane or as in Method G to give LXVIII. The secondary benzylic alcohol is then coverted to thiolacetate LXIX using the conditions of Volante (Tetrahedron lett., 22, 3119, (1981)). The thiol ester is cleaved by hydrazine or an alkoxide, and the side chain is added by nucleophilic substitution in the presence of a base such as Cs2C03. Deprotection of the tertiary alcohol affords LXX, the isomer of LXI.
Methods N, P, Q and R describe the formation of l-(mercaptomethyl)cyclopropaneacetic acid and its ester, derivatives which are useful for the practice of this invention. Method R is described in more detail in Example 161.

Method N
A diester of itaconic acid is cyclopropanated using CH2N2/Pd(OAc)2 (Synthesis, 1981, 714) or Me3SI/n-BuLi (J. Org. Chem., (1973), 38, 3942) or Me3SOI/NaH (J. Am. Chem. Soc., (1965), 87, 1353) or the Simmons-Smith conditions (J. March, Advanced Organic Chemistry, 3rd Edition, 1985, p.
772-773). The cyclopropane ring can also be prepared by addition of a dihalocarbene and reduction of the dihalocyclopropane so obtained. Hydrolysis of the diester and dehydration of the diacid affords the cyclopropanated succinic anhydride. This anhydride can alternatively be prepared directly by the cyclopropanation of itaconic anhydride. Reduction with LiAlH4 or NaBH4 (Can. J. Chem., 56, 1524 (1978)) and acidification afford the lactone. The lactone is opened to the bromoester with HBr (Helv. Chim. Acta.
63, 2508 (1980)) and the bromide is substituted by KSH (Chem. Abstr. 58 P11490b) or AcSNa. Hydrolysis with KOH affords the mercaptoacid.

Method P
A cuprate reagent is prepared from a bromomethyl sulfide such as bromomethyl benzyl 2s sulfide by rea~tion with butyllithium and a copper salt. This reagent is alternatively prepared from the tributyltin derivative as shown. 1,4-Addition of this cuprate to an a,~-unsaturated cyclopropylidene ester yields the protected (l-mercaptomethyl)cyclo-propaneacetate. Deprotection with Na/NH3 when Z is abenzyl group, and hydrolsis, afford the mercaptoacid.

2 ~

Method Q
2-(Bromomethyl)acrylate is reacted with a thiol such as benzyl mercaptan. Reduction of the - ester with a reagent such as diisobutyl-aluminum hydride gives the primary alcohol. Cyclopropanation of the double bond as in Method N affords l-(hydroxy-methyl)cyclopropanemethylthioether. If the ester is reduced first, then it is preferable to effect the cyclopropanation with CH2N2 or by the Simmons-Smith procedure. If the ester is to be cyclopropanated first, it is preferable to use one of the sulfonium reagents in Method N. Mesylation of the primary alcohol, substitution by cyanide, hydrolysis of the nitrile and removal of the Z group (with Na/NH3 when Z is benzyl) yield the desired mercapto acid.

Method R
Diethyl l,l-cyclopropanedicarboxylate is reduced to the diol with a reagent such as LiAlH4 and monoprotected as, for example, a benzoyl ester. The alcohol is mesylated and substituted for a cyanide group. Hydrolysis and esterification affords methyl l-(hydroxymethyl)cyclopropaneacetate. This hydroxyester can also be prepared from the lactone of Method N. The alcohol is mesylated and substituted by a thiolacetaie group. This group can alternatively be introduced by the action of thiolacetic acid/triphenylphosphine/diisopropyl azodicarboxylate (Tetrahedron Lett., 22, 3119 (1981)) on the hydroxyl group. The thiol is then generated in situ with hydrazine.

Assays for Determining BioloEical Activity Compounds of Formula I can be tested using the following assays to determine their mammalian leukotriene antagonist activity and their ability to inhibit leukotriene biosynthesis.

The leukotriene antagonist properties of compounds of the present invention were evaluated using the following assays.

LTD4 Receptor Binding Studies in Guinea Pig Lung Membranes, Guinea Pig Trachea and In vivo Studies in Anesthetized Guinea Pigs A complete description of these three tests is given by T.R. Jones et al., Can. J. Physiol.
Pharmacol., 67, 17-28 (1989).

Compounds of Formula I were tested using the following assays to determine their mammalian leukotriene biosynthesis inhibiting activity.

Determination of Inhibition of 5-Lipoxygenase The activity of 5-lipoxygenase was measured from the conversion of [14C]-arachidonic acid to 5-HETE and 5,12-diHETEs catalyzed by the 10,000 x g supernatant fraction from rat PMN leukocytes, using the procedure of Riendeau and Leblanc (Biochem.
Biophys. Res. Commun., 141, 534-S40, (1986)) with minor modifications. The incubation mixture contained 25 mM Na+/K+ phosphate buffer, p~ 7.3, 1 mM
ATP, 0.5 mM CaC12, 0.5 mM mercaptoethanol and an aliquot of the enzyme preparation in a final volume of 0.2 ml. The enzyme was pre-incubated with the inhibitor for 2 min at 37~C before initiation of the 2 ~ 3~ 2 reaction with the addition of 2 ml of [14C]-arachidonic acid (25,000 DPM) in ethanol to obtain a final concentration of 10 mM. Inhibitors were added as 500-fold concentrated solutions in DMS0. After incubation for 10 min at 37~C, the reaction was stopped by adding 0.8 mL of diethyl ether/methanol/l M citric acid (30:4:1). The samples were centrifuged at 1,000 x g for 5 min and the organic phases analyzed by TLC on Baker Si250F-PA or Whatman silica gel 60A LKGF plates using diethyl ether/petroleum ether/acetic acid (50:50:1) as solvent. The amount of radioactivity migrating at the positions of arachidonic acid, 5-HETE and 5,12-diHETEs was determined using a Berthold TLC
analyzer LB 2842. The activity of 5-lipoxygenase was calculated from the percentage of conversion of arachidonic acid to 5-HETE and 5,12-diHETEs after the 10 min incubation.

Human Polymorphonuclear (PMN) Leukocyte LTB,~ Assay A. Preparation of Human PMN
Human blood was obtained by antecubital venepuncture from consenting volunteers who had not taken medication within the previous 7 days. The blood was immed;ately added to 10% (v/v) trisodium citrate (0.13 M) or 5% (v/v) sodium heparin (1000 IU/mL). PMNs were isolated from anticoagulated blood by dextran sedimentation of erythrocytes followed by centrifugation through Ficoll-Hypaque (specific gravity 1.077), as described by Boyum.l Contaminating erythrocytes were removed by lysis following exposure to ammonium chloride (0.16 M) in Tris buffer (p~ 7.65), and the PMNs resuspended at 5 x 105 cells/mL in HEPES (15 mM)-buffered Hanks balanced salt solution containing Ca2+ (1.4 mM) and Mg2+ (o 7 mM), p~ 7.4. Viability was as~essed by Trypan blue exclusion and was typically greater than 98%.

B. Generation and Radioimmunoassay of LTB/, PMNs (0.5 mL; 2.5 x 105 cells) were placed in plastic tubes and incubated (37~C, 2 min) with test compounds at the desired concentration or vehicle (DMS0, final concentration 0.2%) as control.
The synthesis of LTB4 was initiated by the addition of calcium ionophore A23187 (final concentration 10 mM) or vehicle in control samples and allowed to proceed for S minutes at 37-C. The reactions were then terminated by the addition of cold methanol (O.25 mL) and samples of the entire PMN reaction mixture were removed for radioimmunoassay of LTB4.
Samples (50 mL) of authentic LTB4 of ~nown concentration in radioimmunoassay buffer (RIA) buffer (potassium phosphate 1 mM; disodium EDTA 0.1 mM;
Thimerosa~*0.025 mM; gelatin 0.1%, pH 7.3) or PMN
reaction mixture diluted 1:1 with RIA buffer were added to reaction tubes. Thereafter t3R~-LTB4 (10 nCi in 100 mL ~'A buffer) and LTB4-antiserum (100 mL
of a 1:3000 dilution in RIA buffer) were added and the tubes vortexed. Reactants were allowed to equilibrate by incubation overnight at 4-C. To ~eparate antibody-bound from free LTB4, aliquots (50 mL) of activated charcoal (3% activated charcoal in RIA buffer containing 0.25% Dextra~*T-70) were added, * Trademark b ~ ~ 5 ~

the tubes vortexed, and allowed to stand at room temperature for 10 minutes prior to centrifugation (1500 x g; 10 min; 4-C). The supernatants containing antibody-bound LTB4 were decanted into vials and s Aquasol 2*(4 mL) was added. Radioacti~ity was quantified by liquid scintillation spectrometry.
Preliminary studies established that the amount of methanol carried into the radioimmuno-assay did not influence the results. The specificity of the antiserum and the sensitivity of the procedure have been described by Rokach et al.2 The amount of LTB4 produced in test and control (approx. 20 ng/106 cells) samples were calculated. Inhibitory dose-response curves were constructed using a four-parameter algorithm and from these the IC50 values were determined.

Compounds of Formula I were tested in the following assays to determine their ln vivo activity as both leukotriene antagonist and leukotriene biosynthesis inhibitor.

Asthmatic Rat Assay Rats are obtained from an inbred line of asthmatic rats. Both female (190-250 g) and male (260-400 g) rats are used.
Egg albumin (EA), grade V, crystallized and lyophilized, is obtained from Sigma Chemical Co., St.
Louis. Aluminum hydroxide is obtained from the Regis Chemical Company, Chicago. Methysergide bimaleate was supplied by Sandoz Ltd., Basel.
The challenge and subsequent respiratory recordings are carried out in a clear plastic box with internal dimensions 10 x 6 x 4 inches. The top of the box is removable; in use, it is held firmly in place by four clamps and an airtight seal is maintained by a soft rubber gasket. Through the center of each end of the chamber a Devilbiss nebulizer (No. 40) is inserted via an airtight seal and each end of the box also has an outlet. A
Fleisch No. 0000 pneumotachograph is inserted into one end of the box and coupled to a Grass volumetric pressure transducer (PT5-A) which is then connected to a Beckman Type R Dynograph through appropriate couplers. While aerosolizing the antigen, the outlets are open and the pneumotachograph is isolated from the chamber. The outlets are closed and the pneumotachograph and the chamber are connected during the recording of the respiratory patterns. For challenge, 2 mL of a 3% solution of antigen in saline is placed into each nebulizer and the aerosol is generated with air from a small Potter diaphragm pump operating at 10 psi and a flow of 8 liters/minute.

2 ~ 9 Rats are sensitized by injecting (subcutaneously) 1 mL of a suspension containing 1 mg EA and 200 mg aluminum hydroxide in saline. They are used between days 12 and 24 postsensitization. In order to eliminate the serotonin component of the response, rats are pretreated intravenously 5 minutes prior to aerosol challenge with 3.0 mg/kg of methysergide. Rats are then exposed to an aerosol of 3~/O EA in saline for exactly 1 minute, then their respiratory profiles are recorded for a further 30 minutes. The duration of continuous dyspnea is measured from the respiratory recordings.
Compounds are generally administered either orally 1-4 hours prior to challenge or intravenously 2 minutes prior to challenge. They are either dissolved in saline or 1% methocel or suspended in 1%
methocel. The volume injected is 1 mL/kg (intravenously) or 10 mL/kg (orally). Prior to oral treatment rats are starved overnight. Their activity is determined in terms of their ability to decrease the duration of symptoms of dyspnea in comparison with a group of vehicle-treated controls. Usually, a compound is evaluated at a series of doses and an ED50 is determined. This is defined as the dose (mg/kg) which would inhibit the duration of symptoms by 50%.

Pulmonary Mechanics in Trained Conscious Squirrel Monkeys The test procedure involves placing trained squirrel monkeys in chairs in aerosol exposure chambers. For control purposes, pulmonary mechanics measurements of respiratory parameters are recorded 3 i~ ~ 3 for a period of about 30 minutes to establish each monkey' 8 normal control values for that day. For oral administration, compounds are dissolved or suspended in a 1% methocel solution (methylcellulose, 65HG,400 cps) and given in a volume of l mL/kg body weight. For aerosol administraiton of compounds, a DeVilbiss ultrasonic nebulizer is utilized.
Pretreatment periods vary from 5 minutes to 4 hours before the monkeys are challenged with aerosol doses of either leukotriene D4 (LTD4~ or Ascaris antigen.
Following challenge, each minute of data is calculated by computer as a percent change from control values for each respiratory parameter including airway resistance (RL) and dynamic compliance (Cdyn)~ The results for each test compound are subsequently obtained for a minimum period of 60 minutes post challenge which are then compared to previously obtained historical baseline control values for that monkey. In addition, the overall values for 60 minutes post-challenge for each monkey (historical baseline values and test values) are averaged separately and are used to calculate the overall percent inhibition of LTD4 or Ascaris antigen response by the test compound. For statistical analysis, paired t-test is used.

Prevention of Induced Bronchoconstriction in Allergic Sheep A. Rationale:
Certain allergic sheep with known sensitivity to a specific antigen (Ascaris suum) respond to inhalation challenge with acute and late bronchial responses. The time course of both the acute and the late bronchial responses approximates the time course observed in asthmatics and the pharmacological modification of both responses is similar to that found in man. The effects of antigen in these sheep are largely observed in the large airways and are conveniently monitored as changes in lung resistance or specific lung resistance.

B. Methods:
Animal Preparation: Adult sheep with a mean weight of 35 kg (range, 18 to 50 kg) are used. All animals used meet two criteria: a) they have a natural cutaneous reaction to 1:1,000 or 1 10,000 dilutions of Ascaris suum extract (Greer Diagnostics, Lenois, NC) and b) they have previously responded to inhalation challenge with Ascaris suum with both an acute bronchoconstriction and a late bronchial 2s obstruction (Abraham, W.M., Delehunt, J.C., Yerger, L. and Marchette, B., Am. Rev. Resp. Dis., 128, 839-44 (1983)).

Measurement of Airway Mechanics: The unsedated sheep are restrained in a cart in the prone position with their heads immobilized. After topical anesthesia of the nasal passages with 2% lidocaine 2 ~ Y.~ J ~

solution, a balloon catheter is advanced through one nostril into the lower esophagus. The animals are then intubated with a cuffed endotracheal tube through the other nostril using a flexible fiberoptic bronchoscope as a guide. Pleural pressure is estimated with the esophageal balloon catheter (filled with one ml of air), which is positioned such that inspiration produces a negative pressure deflection with clearly discernible cardiogenic oscillations. Lateral pressure in the trachea is measured with a sidehole catheter (inner dimensions, 2.5 mm) advanced through and positioned distal to the tip of the nasotracheal tube. Transpulmonary pressure, the difference between tracheal pressure and pleural pressure, is measured with a differential pressure transducer (DP45; Validyne Corp., Northridge, CA). Testing of the pressure transducer catheter system reveals no phase shift between pressure and flow to a frequency of 9 Hz. For the measurement of pulmonary resistance (RL), the maximal end of the nasotracheal tube is connected to a pneumotachograph (Fleisch, Dyna Sciences, Blue Bell, PA). The signals of flow and transpulmonary pressure are recorded on an oscilloscope (Model DR-12;
Electronics for Medicine, White Plains, NY) which is linked to a PDP-ll Digital computer (Digital Equipment Corp., Maynard, MA) for on-line calculation of RL from transpulmonary pressure, respiratory volume obtained by integration and flow. Analysis of 10-15 breaths is used for the determination of RL.
Thoracic gas volume (Vtg) is measured in a body plethysmograph, to obtain specific pulmonary resistance (SRL = RL~Vtg).

Aerosol Delivery Systems: Aerosols of Ascaris suum extract (1:20) are generated using a disposable medical nebulizer (Raindrop~, Puritan Bennett), which produces an aerosol with a mass median aerodynamic diameter of 6.2 ~M (geometric standard deviation, 2.1) as determined by an electric size analyzer (Model 3030; Thermal Systems, St. Paul, MN). The output from the nebulizer is directed into a plastic t-piece, one end of which is attached to the nasotracheal tube, the other end of which is connected to the inspiratory part of a ~arvard respirator. The aerosol is delivered at a tidal volume of 500 ml of a rate of 20 per minute. Thus, each sheep receives an equivalent dose of antigen in lS both placebo and drug trials.

~ xperimental Protocol: Prior to antigen challenge baseline measurements of SRL are obtained, infusion of the test compound is started 1 hr prior to challenge, the measurement of SRL repeated and then the sheep undergoes inhalation challenge with Ascaris suum antigen. Measurements of SRL are obtained immediately after antigen challenge and at 1,2,3,4,5,6,6.5,7,7.5 and 8 hr after antigen challenge. Placebo and drug tests are separated by at least 14 days. In a further study, sheep are given a bolus dose of the test compound followed by an infusion of the test compound for 0.5-1 hr prior to ascaris challenge and for 8 hr after ascaris as described above.

2 ~ ~ 3 ~ ~ 9 Statistical Analysis: A Kruskal-Wallis one way ANOVA test was used to compare the acute immediate responses to antigen and the peak late ~response in the controls and the drug treated animals.

The invention is further defined by reference to the following examples, which are intended to be illustrative and not limiting. All temperatures are in degrees Celsius.

Parham and ~.A. Sayed, J. Org. Chem., 39, 2051 (1974)), a solution of 3-(2-(7-chloro-2-quinolinyl)ethenyl)benzaldehyde (1.503 g, 5.12 mmol) (U.S. Patent 4,851,409, July 25, 1989, Example 24, Step 1) in THF (25 mL) was added dropwise at -7~~C. The mixture was stirred for 2 h at -78~C and was quenched with 25% aqueous NH40Ac.
The mixture was acidified to pH 5 with AcOH and extracted with EtOAc. The organic fractions were dried over Na2S04 and evaporated. Flash chromatography of the residue on silica using EtOAc:toluene:AcOH 30:70:1 yielded the title compound.
