BENZOIC ACID DERIVATIVES FOR TREATING LEUKOTRIENE-RELATED DISEASES

Abstract: This invention relates to certain substituted phenyl-(2-hydroxy)ethylpyridine compounds and their ketone and alkyl analogs which are useful as leukotriene antagonists.

Description: Benzoic Acid Derivatives For Treating Leukotriene-related Diseases Scope of the Invention This invention relates to certain substituted pyridyl-(2- hydroxyethyl)benzoic acid derivatives and their ketone analogs which are useful for treating diseases associated with leukotrienes. These compounds are particularly useful in treating diseases attributable to the hydroxyleukotrienes, especially LTB4 and LTB4-agonist active substances. Background of the Invention The family of bioactive lipids known as the leukotrienes exert pharmacological effects on respiratory, cardiovascular and gastrointestinal systems. The leukotrienes are generally divided into two sub-classes, the peptidoleukotrienes (leukotrienes C4, D4 and E4) and the hydroxyleukotrienes (leukotriene B4). This invention is primarily concerned with the hydroxyleukotrienes (LTB) but is not limited to this specific group of leukotrienes. The peptidoleukotrienes are implicated with the biological response associated with the "Slow Reacting Substance of Anaphylaxis" (SRS-A). This response has been expressed in vivo as prolonged bronchoconstriction, in cardiovascular effects such as coronary artery vasoconstriction and numerous other biological responses. The pharmacology of the peptidoleukotrienes include smooth muscle contractions, myocardial depression, increased vascular permeability and enhanced mucous production. By comparison, LTB4 exerts its biological effects through stimulation of leukocyte and lymphocyte functions. It stimulates chemotaxis, chemokinesis and aggregation of polymorphonuclear leukocytes (PMNs). Leukotriene B4 (LTB4) was first described by Borgeat and Samuelsson in 1979, and later shown by Corey and co-workers to be 5(S), 12(R)-dihydroxy-(Z,E,E,Z)-6,8,10,14-eicosatetraenoic acid. It is a product of the arachidonic acid cascade that results from the enzymatic hydrolysis of LTA4. It has been found to be produced by mast cells, polymorphonuclear leukocytes, monocytes and macrophages. LTB4 has been shown to be a potent stimulus in vivo for PMN leukocytes, causing increased chemotactic and chemokinetic migration, adherence, aggregation, degranulation, superoxide production and cytotoxicity. The effects of LTB4 are mediated through distinct receptor sites on the leukocyte cell surface which exhibit a high degree of stereospecificity. Pharmacological studies on human blood PMN leukocytes indicate the presence of two classes of LTB4- specific receptors that are separate from receptors specific for the peptide chemotactic factors. Each of the sets of receptors appear to be coupled to a separate set of PMN leukocyte functions. Calcium mobilization is involved in both mechanisms. LTB4 has been established as an inflammatory mediator in vivo It has also been associated with airway hyperresponsiyeness in the dog as well as being found in increased levels in lung lavages from humans with severe pulmonary dysfunction. In addition, as with the other leukotrienes, LTB4 has been implicated in inflammatory bowel disease, rheumatoid arthritis, gout, and psoriasis. They are critically involved in mediating many types of cardiovascular, pulmonary, dermatological, renal, allergic, and inflammatory diseases including asthma, adult respiratory distress syndrome, cystic fibrosis, psoriasis, and inflammatory bowel disease. By antagonizing the effects of LTB4, or other pharmacologically active mediators at the end organ, for example airway smooth muscle, the compounds and pharmaceutical compositions of the instant invention are valuable in the treatment of diseases in subjects, including human or animals, in which leukotrienes are a key factor. SUMMARY OF THE INVENTION The compounds of this invention are represented by formula (I) or a pharmaceutically acceptable salt or N-oxide thereof where T is CO or CH(OH) R is Ci to C20 -aliphatic, unsubstituted or substituted phenyl Ci to Cio-aliphatic where substituted phenyl has one or more radicals selected from the group consisting of lower alkoxy, lower alkyl, trihalomethyl, and halo, or R is Ci to C20 _a l h tic-O-, or R is unsubstituted or substituted phenyl C to Cj o-aϋphatic-O- where substituted phenyl has one or more radicals selected from the group consisting of lower alkoxy, lower alkyl, trihalomethyl, and halo; Rl is -(Ci to C5 aliphatic)R3,-(Cl to C5 aliρhatic)CHO, -(Ci to C5 aliphatic)CH20R7, R3, -CH2OH or -CHO; R2 and R3 are independently -COR4 where R4 is -OH, a pharmaceutically acceptable ester-forming group -OR5 , or -OX where X is a pharmaceutically acceptable cation, or R4 is -N(R6)2 where R6 is H, or an aliphatic group of 1 to 10 carbon atoms or a cycloalkyl- (CH2)n- group of 4 to 10 carbons where n is 0-3 or both R6 groups form a ring having 4 to 6 carbons, or R2 is an amine, amide or sulfonamide; and R7 is hydrogen, Cl to C6-alkyl, or Ci to C6-acyl. In another aspect, this invention covers pharmaceutical compositions containing the instant compounds and a pharmaceutically acceptable excipient. Treatment of diseases related to or caused by leukotrienes, particularly LTB4, or related pharmacologically active mediators at the end organ, are within the scope of this invention. This treatment can be effected by administering one or more of the compounds of formula I alone or in combination with a pharmaceutically acceptable excipient in an amount sufficient to prevent disease or treat it once it has occurred. In yet another aspect, this invention relates to a method for making the compounds of this invention. This aspect of the invention is illustrated in the reaction schemes given below and in the examples set forth in this specification. DETAILED DESCRIPTION OF THE INVENTION The following definitions are used in describing this invention and setting out what the inventors believe to be their invention herein. "Aliphatic" is intended to include saturated and unsaturated radicals. This includes normal and branched chains, saturated or mono or poly unsaturated chains where both double and triple bonds may be present in any combination. The phrase "lower alkyl" means an alkyl group of 1 to 6 carbon atoms in any isomeric form, but particularly the normal or linear form. "Lower alkoxy" means the group lower alkyl-O-. "Halo" means fluoro, chloro, bromo or iodo. "Acyl" means the radical having a terminal carbonyl carbon. When reference is made to a substituted phenyl ring, it is meant that the ring can be substituted with one or more of the named substituents as may be compatible with chemical synthesis. Multiple substituents may be the same or different, such as where there are three chloro groups, or a combination of chloro and alkyl groups and further where this latter combination may have different alkyl radicals in the chloro/alkyl substituent pattern. The phrase "a pharmaceutically acceptable ester-forming group" in R2 and R3 covers all esters which can be made from the acid function(s) which may be present in these compounds. The resultant esters will be ones which are acceptable in their application to a pharmaceutical use. By that it is meant that the mono- or diesters will retain the biological activity of the parent compound and will not have an untoward or deleterious effect in their application and use in treating diseases. Such esters are, for example, those formed with one of the following radicals representing R5: Ci to Cio alkyl, phenyl-Ci - C6 alkyl, cycloalkyl, aryl, arylalkyl, alkylaryl, alkylarylalkyl, aminoalkyl, indanyl, pivaloyloxymethyl, acetoxy methyl, propionyloxymethyl, glycyloxy methyl, phenylglycyloxymethyl, or thienylglycyloxy methyl. Aryl includes phenyl and naththyl, or heteroaromatic radicals like furyl, thienyl, imidazolyl, triazolyl or tetrazolyl. The most preferred ester-forming radicals are those where R5 is alkyl, particularly alkyl of 1 to 10 carbons, [ie CH3-(CH2)r where n is 0-9], or phenyl-(CH2)n- where n is 0-4. When R2 is referred to as being an amine, that includes the radical -NH2 and mono- or dialkylate derivatives of this -NH2 radical. Preferred alkylated amines are the mono- or disubstituted amines having 1 to 6 carbons. When R2 is referred to as being an amide, that includes all acylate derivatives of the NH2 radical. The preferred amides are those having 1 to 6 carbons. Where there is an acid group, amides may be formed. The most preferred amides are those where -R6 is hydrogen or alkyl of 1 to 6 carbon atoms. Particularly preferred is the diethylamide. The hydroxyl group of the 2-hydroxyethylene linking group may be esterified. Lower alkyl acids of 1 to 6 carbon atoms may be used to form such esters using standard reaction conditions. This hydroxyl group also may be converted to an ether if so desired. Again, such reactions are well known in the synthetic chemical arts. Pharmaceutically acceptable salts of the instant compounds are also intended to be covered by this invention. These salts will be ones which are acceptable in their application to a pharmaceutical use. By that it is meant that the salt will retain the biological activity of the parent compound and the salt will not have untoward or deleterious effects in its application and use in treating diseases. Pharmaceutically acceptable salts are prepared in a standard manner. The parent compound in a suitable solvent is reacted with an excess of an organic or inorganic acid, in the case of acid addition salts of a basic moiety, or an excess of organic or inorganic base in the case where R 4 is OH. Representative acids are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, acetic acid, maleic acid, succinic acid or methanesulfonic acid. Cationic salts are readily prepared from alkali metal bases such as sodium, potassium, calcium, magnesium, zinc, copper or the like and ammonia. Organic bases include the mono or disubstituted amines, ethylene diamine, piperazine, amino acids, caffeine, tromethamine, other tris compounds and the like. Oxides of the pyridyl ring nitrogen may be prepared by means known in the art and as illustrated herein. These are to be considered part of the invention. If by some combination of substituents, a chiral center is created or another form of an isomeric center is created in a compound of this invention, all forms of such isomer(s) are intended to be covered herein. Compounds with a chiral center may be administered as a racemic mixture or the racemates may be separated and the individual enantiomer used alone. As leukotriene antagonists, these compounds can be used in treating a variety of diseases associated with or attributing their origin or affect to leukotrienes, particularly LTB4. Thus it is expected that these compounds can be used to treat allergic diseases of a pulmonary and non-pulmonary nature. For example these compounds will be useful in antigen-induced anaphylaxis. They are useful in treating asthma and allergic rhinitis. Ocular diseases such as uveitis, and allergic conjunctivitis can also be treated with these compounds. The preferred compounds of this invention are those where R is alkoxy, particularly alkoxy of 8 to 15 carbon atoms or substituted or unsubstituted phenyl Ci to Cio-aliphatic-O-; Rj is -(Ci to C5 aliphatic)R3 or -(Ci to C 5 aliphatic)CH20R7, and R2 is -COOH or N(A)(B) where A is H, or alkyl of 1 to 6 carbons and B is H, alkyl of 1 to 6 carbons, acyl of 1 to 6 carbons or -SO2R8 where R% is -CF3, Ci to C6 alkyl or phenyl. The more preferred compounds of this invention are those where R is alkoxy of 8 to 15 carbon atoms or alkoxy-substituted phenyl-Ci to Cg-alkoxy; Ri is COR4, -CH2CH2COR3 or -CH=CH-COR3 ; and R2 is -COOH or -NHSθ2Rδ > particularly where R2 is at the meta position and R δ is -CF3. The most preferred compounds are set out in Figure II. * The methylene carbon is substituted on the pyridyl ring. ** Trans configuration. Synthesis These compounds may be made by the starting materials, intermediates and reagents and the synthetic steps set out in the following reaction flow charts. These charts trace the path used to make these compounds and are based on the detailed chemistry set out in the Examples recited below. These flow charts are intended to act as a road map to guide one from known starting materials to the desired products. These specific starting materials, intermediates and reagents are only given to illustrate the general case and are not intended to limit the chemistry illustrated thereby. Reagents, intermediates, temperatures, solvents, reaction times, work -up procedures all may be varied to accommodate differences and optimize the particular conditions for making a particular compound. Such variations will be apparent to a chemist or will not require more than minimal experimentation to optimize conditions and reagents for a particular step. These reaction schemes first illustrate how to make certain portions of the R group which are not commercially available, then illustrate a means to assemble the whole compound using the materials from Reaction Scheme 1 or commercially available R- forming groups. The preparation of certain embodiments of R are given in Scheme 1. (a) H 3 CO-Ph-I ≡≡— (CH 2 ) n OSi(Ph) 2 -t-BuPh 2 ► (b ) P [(Ph) 3 P] 2 Cl 2 H 2 , Pd-C H 3 CO— — s≡≡— (CH 2 ) n OSi(Ph) 2 -t-BuPh 2 ► (c) (d) H 3 CO-^^-(CH 2 ) n+2 -OH __ ___ l ^ H 3 CO- ~ (CH 2 ) n+2 -OTs Py r (e) (f) In those instances where an ω-yn-1-ol is not commercially available, it can be prepared from a corresponding 3-yn-l-ol by treating the alcohol with a strong base. An alkali metal amide may be used. The alcohol is then protected in order to add the desired phenyl group at the terminal triple bond. A silyl ether was formed in this instance; it illustrates the general case. A halo-substituted-phenyl adduct is used to add the phenyl group at the triple bond. The silyl group is removed and the resulting alcohol converted to the tosylate, or another group which is sufficiently reactive so as to provide ready formation of an ether later in the synthesis of these compound. Scheme 1(b) illustrates another method for making certain alkoxy-substitutedphenylalkoxy R groups. Scheme Kb) (a) TsCl LiAlH (b) (C) While the methoxyphenyl compound is illustrated here, this series of steps and reagents may be used to make other ω-(unsubstituted)phenylaliphatic or ω-(substituted)phenylaliphatic groups denoted by R. The starting material, the benzaldehydes, are commercially available or can be readily made by known methods. To make the acid, first an alkylsilazide is added to an inert solvent under an inert atmosphere. Then the phosphonium salt is added. This addition can be done at room temperature or thereabouts. After a brief period of mixing, this mixture is usually a suspension, the benzaldehyde is added slowly at about room temperature. A slight molar excess of the phosphonium salt is employed. After an additional brief period of stirring at about room temperature, the reaction is quenched with water. The solution is acidified and the acid (a) extracted with a suitable organic solvent. Further standard separatory and purification procedures may be employed as desired. The alcohol is made by reducing the acid using a reducing agent. Lithium aluminum hydride or similar reducing agents may be employed and conditions may be varied as needed to effect the reduction. The tosylate is prepared in an inert solvent employing p-toluenesulfonylchloride and a base such as pyridine. Suitable conditions include carrying out the reaction at room temperature or thereabouts for a period of 1 to 5 hours. Other suitable leaving groups similar in function to the tosylate may be prepared and will be useful as a means for adding this R moiety to the pyridyl ring. Compounds of formula I can then be synthesized by the sequence of steps outlined in the following schemes. Scheme 2 (2b) (2c) (2d) First 2,6-lutidine-α 2 ,3-diol is oxidized to the 3-hydroxy-6- methyl-2-pyridine carboxaldehyde. This aldehyde is then treated with a 1-halosubstituted group which adds to the 3-hydroxy group to form an ether. This reaction is effected by base, for example a carbonate such as K2CO2. Hydrazine hydrate is then used to form an aminohydrazone. This reaction is carried out at an elevated temperature. The reaction mixture is then cooled and treated with a base before recovering the aminohydrazone. This hydrazone is then converted to a triazolo[l,5-α]pyridine(2a) by means of O2 or another oxidizing agent such as KFe(CN)6- If nickel peroxide is used, 'he reaction can be effected at room temperature or thereabouts, though it may require an extended reaction time. For the nickel peroxide process, an inert atmosphere is preferred, as are dry conditions. Other oxidizing agents may require elevated temperatures. The 2-hydroxyethyl product is then made by first preparing i n situ a reagent capable of extracting a proton from the triazolopyridine compound after which the triazolo compound is added followed by a halobenzaldehyde. A useful base is lithium diisopropylamide. It is preferable to prepare it at reduced temperatures, i.e. -40 to 0°C or thereabouts. After the triazolopyridine and benzaldehyde are added, the reaction is allowed to run its course at room temperature or thereabouts. A carbonylation reaction is then carried out to introduce a carboxyl group into the phenyl ring. This is effected by Pd(OAc)2 and gaseous carbon monoxide in an appropriate solvent, preferably at an elevated temperature, i.e. 50-100°C. This gives the carbomethoxy- substituted phenyl compound (2b). Treating the resulting triazolo compound with Br2 destroys the triazole ring and brominates the resulting 2-position carbon on the pyridine ring to afford the 2-(α,α-dibromomethyl)pyridyl adduct. This reaction is best carried out at reduced temperature, i.e. about 0°C and is complete in about an hour or so. Silver nitrate oxidation gives aldehyde (2c). A Wittig reaction is then carried out to form the carbomethoxyethylene group at position 2 on the pyridyl ring. This compound can be treated with a base to hydrolyze the esters, which is then acidified if the free acid (2d) is desired. Alternatively, the ethylene group at position 2 can be saturated by catalytic hydrogenation, then saponified using a base, which gives the salt, or thereafter acidifying the soluton to obtain the free acid (see Scheme 3 below). The acid can be converted to a pharmaceutically acceptable salt or esterified by known means. Amides can be made from the acids using known procedures. Analogs of the compounds in Scheme 2 where Ri is an alkanoic acid can be made by simply hydrogenating the unsaturated bonds in that chain. Such process is illustrated in Scheme 3. Reducing the double bond is effected by catalytic mean using a heavy metal catalyst and hydrogen gas. Mild conditions will suffice. The illustrated esters can be hydrolyzed with base and further converted to other forms of formula I from there or transesterification can be used to convert to another ester. Compounds where Ri contains a terminal -OH group, or an ester thereof, can be prepared by the series of steps given in Scheme 4. Scheme 4 (4a) (4b) Starting material is derived from Scheme 2, then carried through that set of steps, except that the R 2 carbomethoxy function is not introduced until after the Ri alcohol has been prepared. Also, separately and apart from the steps in Scheme 2, the Ri carbomethoxy group can be reduced to the alcohol using a reducing agent such as diisobutylaluminum hydride (DIBAL) or a similar reducing agent. Catalytic hydrogenation can be used to saturate the ethylene group at position 2 on the pyridyl ring. A base can be used to saponify the ester to obtain the acid salt, or that salt can be acidified if the free acid is desired. Each of the products containing an hydroxyl group in Schemes 2-4 can be oxidized to the corresponding ketone, that is where T is - CH 2 C(0)-, by means of a mild oxidizing agent. Formulations Pharmaceutical compositions of the present invention comprise a pharmaceutical carrier or diluent and an amount of a compound of the formula (I) or a pharmaceutically acceptable salt, such as an alkali metal salt thereof, sufficient to produce the inhibition of the effects of leukotrienes. When the pharmaceutical composition is employed in the form of a solution or suspension, examples of appropriate pharmaceutical carriers or diluents include: for aqueous systems, water; for non- aqueous systems, ethanol, glycerin, propylene glycol, corn oil, cottonseed oil, peanut oil, sesame oil, liquid parafins and mixtures thereof with water; for solid systems, lactose, kaolin and mannitol; and for aerosol systems, dichlorodifluoromethane, chlorotrifluoroethane and compressed carbon dioxide. Also, in addition to the pharmaceutical carrier or diluent, the instant compositions may include other ingredients such as stabilizers, antioxidants, preservatives, lubricants, suspending agents, viscosity modifiers and the like, provided that the additional ingredients do not have a detrimental effect on the therapeutic action of the instant compositions. The nature of the composition and the pharmaceutical carrier or diluent will, of course, depend upon the intended route of administration, for example parenterally, topically, orally or by inhalation. In general, particularly for the prophylactic treatment of asthma, the compositions will be in a form suitable for administration by inhalation. Thus the compositions will comprise a suspension or solution of the active ingredient in water for administration by means of a conventional nebulizer. Alternatively the compositions will comprise a suspension or solution of the active ingredient in a conventional liquified propellant or compressed gas to be administered from a pressurized aerosol container. The compositions may also comprise the solid active ingredient diluted with a solid diluent for administration from a powder inhalation device. In the above compositions, the amount of carrier or diluent will vary but preferably will be the major proportion of a suspension or solution of the active ingredient. When the diluent is a solid it may be present in lesser, equal or greater amounts than the solid active ingredient. For parenteral administration the pharmaceutical composition will be in the form of a sterile injectable liquid such as an ampule or an aqueous or nonaqueous liquid suspension. For topical administration the pharmaceutical composition will be in the form of a cream, ointment, liniment, lotion, pastes, and drops suitable for administration to the eye, ear, or nose. For oral administration the pharmaceutical composition will be in the form of a tablet, capsule, powder, pellet, atroche, lozenge, syrup, liquid, or emulsion. Usually a compound of formula I is administered to a subject in a composition comprising a nontoxic amount sufficient to produce an inhibition of the symptoms of a disease in which leukotrienes are a factor. When employed in this manner, the dosage of the composition is selected from the range of from 50 mg to 1000 mg of active ingredient for each administration. For convenience, equal doses will be administered 1 to 5 times daily with the daily dosage regimen being selected from about 50 mg to about 5000 mg. The pharmaceutical preparations thus described are made following the conventional techniques of the pharmaceutical chemist as appropriate to the desired end product. Included within the scope of this disclosure is the method of treating a disease mediated by LTB4 which comprises administering to a subject a therapeutically effective amount of a compound of formula I, preferably in the form of a pharmaceutical composition. For example, inhibiting the symptoms of an allergic response resulting from a mediator release by administration of an effective amount of a compound of formula I is included within the scope of this disclosure. The administration may be carried out in dosage units at suitable intervals or in single doses as needed. Usually this method will be practiced when relief of symptoms is specifically required. However, the method is also usefully carried out as continuous or prophylactic treatment. It is within the skill of the art to determine by routine experimentation the effective dosage to be administered from the dose range set forth above, taking into consideration such factors as the degree of severity of the condition or disease being treated, and so forth. Pharmaceutical compositions and their method of use also include the combination of a compound of formula I with Hi blockers where the combination contains sufficient amounts of both compounds to treat antigen-induced respiratory anaphylaxis or similar allergic reaction. Representative Hi blockers useful here include cromolyn sodium, compounds from the ethanolamines (diphenhydramine), ethylenediamines (pyrilamine), the alkylamines (chlorpheniramine), the piperazines (chlorcyclizine), and the phenothiazines (promethazine). Hi blockers such as 2-[4-(5-bromo-3- methylpyrid-2-yl)butylamino] -5-[(6-methylpyrid-3 -yl)methyl] -4- pyrimidone are particularly useful in this aspect of the invention. Bioassays The specificity of the antagonist activity of a number of the compounds of this invention is demonstrated by relatively low levels of antagonism toward agonists such as potassium chloride, carbachol, histamine and PGF2- The receptor binding affinity of the compounds used in the method of this invention is measured by the ability of the compounds to bind to [ 3 H] -LTB 4 binding sites on human U937 cell membranes. The LTB4 antagonists activity of the compounds used in the method of this invention is measured by their ability to antagonize in a dose dependent manner the LTB4 elicited calcium transient measured with fura-2, the fluorescent calcium probe. The methods employed were as follows. U937 Cell Culture Conditions U937 cells were obtained from Dr. John Bomalaski (Medical College of PA) and Dr. John Lee (SK&F, Dept. of Immunology) and grown in RPMI-1640 medium supplemented with 10% (v/v) heat inactivated fetal calf serum, in a humidified environment of 5% CO2, 95% air at 37°C. Cells were grown both in T-flasks and in Spinner culture. For differentiation of the U937 cells with DMSO to monocyte- like cells, the cells were seeded at a concentration of 1 x 10 5 cells/ml in the above medium with 1.3% DMSO and the incubation continued for 4 days. The cells were generally at a density of 0.75-1.25 x 10 6 cells/ml and were harvested by centrifugation at 800 x g for 10 min. Preparation of U937 Cell Membrane Enriched Fraction Harvested U937 cells were washed with 50 mM Tris-HCl, pH 7.4 at 25°C containing 1 mM EDTA (buffer A). Cells were resuspended in buffer A at a concentration of 5 x 10 7 cells/ml and disrupted by nitrogen cavitation with a Parr bomb at 750 psi for 10 min at 0°C . The broken cell preparation was centrifuged at 1,000 x g for 10 min. The supernatant was centrifuged at 50,000 x g for 30 min. The pellet was washed twice with buffer A. The pellet was resuspended at about 3 mg membrane protein/ml with 50mM Tris-HCl, pH 7.4 at 25°C and aliquots were rapidly frozen and stored at -70°C . [ 3 H] -LTB4 binding assays were performed at 25°C, in 50 mM Tris-HCl (pH 7.5) buffer containing 10 mM CaCl 2 , 10 mM MgCl 2 , [ 3 H] - LTB4, U937 cell membrane protein (standard conditions) in the presence (or absence of varying concentrations of LTB4, or SK&F compounds. Each experimental point represents the means of triplicate determinations. Total and non-specific binding of [ 3 H] -LTB4 were determined in the absence or presence of 2 μM of unlabeled LTB4, respectively. Specific binding was calculated as the difference between total and non-specific binding. The radioligand competition experiments were performed, under standard conditions, using approximately 0.2 nM [ 3 H]-LTB4, 20-40 μg of U937 cell membrane protein, increasing concentrations of LTB4 (0.1 nM to 10 nM) or other competing ligands (0.1 μM to 30 μM) in a reaction volume of 0.2 ml and incubated for 30 minutes at 25°C. The unbound radioligand and competing drugs were separated from the membrane bound ligand by a vacuum filtration technique. The membrance bound radioactivity on the filters was determined by liquid scintillation spectrometry. Saturation binding experiments for U937 cells were performed, under standard conditions, using approximately 15-50 μg of U937 membrane protein and increasing concentrations of [ 3 H] -LTB 4 (0.02- 2.0 mM) in a reaction volume of 0.2 ml and incubation at 22°C, for 30 minutes. LTB4 (2 μM) was included in a separate set of incubation tubes to determine non-specific binding. The data from the saturation binding experiments was subjected to computer assisted non-linear least square curve fitting analysis and further analyzed by the method of Scatchard. Uptake of Fura-2 by Differentiated U937 Cells Harvested cells were resuspended at 2 x 10 6 cells/ml in Krebs Ringer Hensilet buffer containing 0.1 % BSA (RIA grade), 1.1 mM MgSθ4, 1.0 mM CaCtø and 5 mM HEPES (pH 7.4, buffer B). The diacetomethoxy ester of fura-2 (fura-2/AM) was added to a final concentration of 2 μM and cells incubated in the dark for 30 minutes at 37°C. The cells were centrifuged at 800 x g for 10 minutes and resuspended at 2 x 10 6 cells/ml in fresh buffer B and incubated at 37°C for 20 minutes to allow for complete hydrolysis of entrapped ester. The cells were centrifuged at 800 x g for 10 minutes and resuspended in cold fresh buffer B at 5 x 10 6 cells/ml. Cells were maintained on ice in the dark until used for fluorescent measurements. Fluorescent Measurements-Calcium Mobilization The fluorescence of fura-2 containing U937 cells was measured with a fluorometer designed by the Johnson Foundation Biomedical Instrumentation Group. Fluorometer is equipped with temperature control and a magnetic stirrer under the cuvette holder. The wave lengths are set at 339 nm for excitation and 499 nm for emission. All experiments were performed at 37°C with constant mixing. U937 cells were diluted with fresh buffer to a concentration of 1 x 10 6 cells/ml and maintained in the dark on ice. Aliquots (2 ml) of the cell suspension were put into 4 ml cuvettes and the temperature brought up to 37°C, (maintained in 37°C, water bath for 10 min). Cuvettes were transferred to the fluorometer and fluorescence measured for about one minute before addition of stimulants or antagonists and followed for about 2 minutes post stimulus. Agonists and antagonists were added as 2 μl aliquots. Antagonists were added first to the cells in the fluorometer in order to detect potential agonist activity. Then after about one minute 10 nM LTB4 (a near maximal effective concentration) was added and the maximal Ca 2+ mobilization [Ca 2+ ]i was calculated using the following formula: F-Fmin) [Ca + ] i = 224i \Fmax-F\ F was the maximum relative fluorescence measurement of the sample. Fmax was determined by lysing the cells with 10 μl of 10% Triton X- 100 (final concentration 0.02%). After Fmax was determined 67 μl of 100 mM EDTA solution (pH 10) was added to totally chelate the Ca 2+ and quench the fura-2 signal and obtain the Fmin. The [Ca 2+ ]i level for 10 nM LTB4 in the absence of an antagonist was 100% and basal [Ca 2+ ]i was 0%. The IC50 concentration is the concentration of antagonist which blocks 50% of the 10 nM LTB4 induced [Ca 2+ ]i mobilization. The EC50 for LTB4 induced increase in [Ca 2+ ]i mobilization was the concentration for half maximal increase. The Ki for calcium mobilization was determined using the formula: With the experiments described, the LTB4 concentration was 10 nM and the EC50 was 2 nM. Results for compounds tested by these methods are given in Figure III. Figure III Binding. IOvn.
