## Title
Functionalized tris(hydroxyphenyl) compounds

## Abstract

Compounds having the formula I: ##STR1## are antagonists of the actions of leukotrienes. These compounds are useful as anti-asthmatic, anti-allergic, anti-inflammatory, and cytoprotective agents. They are also useful in treating angina, cerebral spasm, glomerular nephritis, hepatitis, endotoxemia, uveitis, and allograft rejection.

## Background
The leukotrienes constitute a group of locally acting hormones, produced in living systems from arachidonic acid. The major leukotrienes are Leukotriene B4 (abbreviated at LTB.sub.4), LTC.sub.4, LTD.sub.4, and LTE.sub.4. The biosynthesis of these leukotrienes begins with the action of the enzyme 5-lipoxygenase on arachidonic acid to produce the epoxide known as Leukotriene A.sub.4 (LTA.sub.4), 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 is found in the book 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.

Several classes of compounds exhibit the ability to inhibit the biosynthesis of leukotrienes in mammals, especially humans.

EP 181,568 describes a series of compounds of the general formula:

which differ from the present invention in not having a cycloalkyl or phenyl substituent (R) attached directly to the alkylene chain Z and in not having the Q substituent in the preferred embodiment of the present invention attached by a sulfur atom to the alkylene chain.

U.S. Pat. No. 4,631,287 contains compounds of the formula:

which differ from the present invention in that the R.sub.3 and R.sub.4 substituents which contain a carboxy group (corresponding to the Q substituent of the present invention) are attached directly to Ar.sub.1 by an oxygen atom. Further, when they contain an aryl group, it is either attached directly to Ar.sub.1 or is attached through an oxygen atom. Furthermore, R.sub.3 or R.sub.4 do not simultaneously include the Q substituent of the present invention and the cycloalkyl or phenyl substituent of the present invention.

EP 200,101 and Australian Patent application 56398/86 disclose compounds of the formula: --Y--Z.sub.3 -R.sub.4)

which differ from the compounds of the present invention in that the substituent unit (Z.sub.2 --Y--Z.sub.3 --R.sub.4) does not simultaneously contain the cycloalkyl or phenyl and Q substituents of the present invention.

W0 87/05510 discloses compounds of the general formula: ##STR2## which differ from the compounds of the present invention in that they contain the heterocyclic tetrazole moiety which is absent from the present compounds, and in that the phenyl group present in the R.sub.2 and R.sub.3 substituents is unsubstituted.

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.

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 conjunctivitis, and the like, 3) inflammation such as arthritis or inflammatory bowel disease, 4) pain, 5) skin disorders such as 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, 1 1) trauma or shock states such as bum 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 CCl.sub.4 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 noxious 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.

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.

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 0.00 1 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 is 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.

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 1 00 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 an NSAID 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).

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 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 an of pharmacy.

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. 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 a compound of Formula I in suitable propellants, such as fluorocarbons or hydrocarbons.

Suitable topical formulations of a compound of formula 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 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 carders 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. Pat. Nos. 3,845,770; 3,916,899; 3,536,809; 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 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 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 for injection to a total volume of 1 mL ______________________________________ Tablet                  mg/tablet ______________________________________ Compound of Formula I   25 Microcrystalline Cellulose 415 Povidone                14.0 Pregelatinized Starch   43.5 Magnesium Stearate      2.5 500 ______________________________________ Capsule                 mg/capsule ______________________________________ Compound of Formula I   25 Lactose Powder          573.5 Magnesium Stearate      1.5 600 ______________________________________ Aerosol                 Per canister ______________________________________ Compound of Formula I   24       mg Lecithin, NF Liquid Concentrate 1.2      mg Trichlorofluoromethane, NF 4.025    g Dichlorodifluoromethane, NF 12.15    g ______________________________________

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 ratio 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.

Compounds of the present invention can be prepared according to the following methods. In these schemes: ##STR11##

Allyl or vinylmagnesium bromide is added to the aldehyde III to yield IV. (A description of the formation of III where Y is CH.dbd.CH is given in the Examples. For Y.dbd.CH.sub.2 CH.sub.2 and 1,2-cyclopropyl, see U.S. Pat. No. 5,104,882, Example 3, Step 2 and Styrene 4 respectively.) The homoallylic or allylic alcohol IV is then treated with the suitable bromide or iodide V in the presence of Pd at 100.degree. C. to give VI. Chiral reduction of the ketone is done using a reagent such as (-)-B-chlorodiisopinocampheylborane. Formation of the mesylate and substitution by the thiol VIII in the presence of a base such as NaH or Cs.sub.2 CO.sub.3 affords IX. When Q is an ester, hydrolysis yields the acid X. The epimer of IX can be obtained by using the (+) enantiomer of the chiral reagent for the reduction of VI.

Starting from XI, the synthesis is like Method A, except that the chiral reducing agent is the oxazaborolidine XIV. Deprotection of the tetrahydropyranyl protecting group is performed with pyridinium p-toluenesulfonate in methanol and the primary alcohol is oxidized to the aldehyde XVII with MnO.sub.2. The quinoline moiety is added at the end of the synthesis by a Wittig coupling reaction between XVII and the phosphonium XVIIa in the presence of a base such as potassium t-butoxide.

Vinylmagnesium bromide is added to the aldehyde III followed by oxidation to give enone XIX. Then, an appropriate copperzincate reagent XX (prepared from the corresponding iodide, zinc powder and copper cyanide) is added to the enone XIX in the presence of chlorotrimethylsilane to yield, after hydrolysis of the enol ether, the ketone XXI. Chiral reduction gives the alcohol XXII. Alternatively, this alcohol can be obtained by addition of the appropriate copper-zincate reagent XXIII onto the aldehyde III in the presence of boron trifluoride etherate followed by oxidation and chiral reduction. Mesylate formation followed by displacement by the thiol VIII affords XXIV. When Q is an ester, hydrolysis yields the carboxylate XXV.

The .beta.-keto ester XXVI (see U.S. Pat. No. 5,104,882) is alkylated with the appropriate reagent XXVII (such as 2-chloromethylpyridine) in the presence of a base such as NaH or t-BuOK to yield XXVIII. Decarbomethoxylation is accomplished by heating under acid or neutral conditions and the resulting ketone XXIX is reduced enantioselectively to the alcohol XXX. Mitsunobu inversion (Synthesis, pp 1-28, 1981) using thiolacetic acid as the nucleophile gives the thioacetate XXXI. Treatment with hydrazine generates the corresponding thiol which, upon reaction with a suitable mesylate XXXII followed by hydrolysis, yields the carboxylate XXXIII. Alternatively, the thiol can be treated with a substituted acrylic acid XXXIV to yield carboxylate XXXV.

Aldehyde III is converted into epoxide XXXVI using trimethylsulfoxonium ylid. Addition of a suitable organolithium reagent XXXVII gives the racemic alcohol XXXVIII.

Oxidation using tetrapropylammonium perruthenate and N-methylmorpholine N-oxide followed by chiral reduction gives alcohol XXX. Transformation of the latter into carboxylate XXXIII is accomplished as in Method C or D. ##STR12##

The leukotriene antagonist properties of the compounds of the present invention are evaluated using the following assays. Cells (a human monocytic cell line);

The above assays are described in T. R. Jones et al., Can. J. Physiol. Pharmacol., 1991,69, 1847-1854.

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 is supplied by Sandoz Ltd., Basel.

The challenge and subsequent respiratory recordings are carried out in a clear plastic box with internal dimensions 10.times.6.times.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 inserted into one end of the box and coupled to a Grass volumetric pressure transducer (PT5-A) which is then connected to a Buxco Electronics preamplifier (Buxco Electronics Inc., Sharon, Conn.). The preamplifier is connected to a Beckman Type R Dynograph and to a s Buxco computer consisting of waveform analyzer, Data Acquisition Logger with Buxco software. 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.

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 post sensitization. In order to eliminate the serotonin component of the response, rats are pretreated intravenously 5 minutes prior to aerosol challenge with 3.0 .mu.g/kg of methysergide. Rats are then exposed to an aerosol of 3% 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 by the Buxco computer.

Compounds are generally administered either orally 2-4 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. The activity of compounds is determined in terms of their ability to decrease the duration of antigen-induced dyspnea in comparison with a group of vehicle-treated controls. Usually, a compound is evaluated at a series of doses and an ED.sub.50 is determined. This is defined as the dose (mg/kg) which would inhibit the duration of symptoms by 50%.

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 for a period of about 30 minutes to establish each monkey's normal control values for that day. For oral administration, compounds are dissolved or suspended in a 1% methocel solution (methylcellulose, 65 HG, 400 cps) and given in a volume of 1 mL/kg body weight. For aerosol administration 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 D.sub.4 (LTD.sub.4) or Ascaris suum antigen; 1:25 dilution.

Following challenge, each minute of data is calculated by computer as a percent change from control values for each respiratory parameter including airway resistance (R.sub.L) and dynamic compliance (C.sub.dyn). 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 LTD.sub.4 or Ascaris antigen response by the test compound. For statistical analysis, paired t-test is used. (References: McFarlane, C. S. et al., Prostaglandins, 28, 173-182 (1984), and McFarlane, C. S. et al., Agents Actions, 22, 63-68 (1987).)

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, N.C.) and b) they have previously responded to inhalation challenge with Ascaris suum with both an acute bronchoconstriction and a late bronchial obstruction (W. M. Abraham et al., 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 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 dimension, 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, Calif.). For the measurement of pulmonary resistance (R.sub.L), the maximal end of the nasotrachel 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, N.Y.) which is linked to a PDP-11 Digital computer (Digital Equipment Corp., Maynard, Mass.) for on-line calculation of R.sub.L from transpulmonary pressure, respiratory volume obtained by integration and flow. Analysis of 10-15 breaths is used for the determination of R.sub.L. Thoracic gas volume (V.sub.tg) is measured in a body plethysmograph, to obtain specific pulmonary resistance (SR.sub.L =R.sub.L .multidot.V.sub.tg).

Aerosol Delivery Systems: Aerosols of Ascaris suum extract (1:20) are generated using a disposable medicalnebulizer (Raindrop.RTM., Puritan Bennett), which produces an aerosol with a mass median aerodynamic diameter of 6.2 .mu.M (geometric standard deviation, 2.1) as determined by an electric size analyzer (Model 3030; Thermal Systems, St. Paul, Minn.). 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 pan of a Harvard 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 both placebo and drug trials.

Experimental Protocol: Prior to antigen challenge baseline measurements of SR.sub.L are obtained, infusion of the test compound is started 1 hr prior to challenge, the measurement of SR.sub.L repeated and then the sheep undergoes inhalation challenge with Ascaris suum antigen. Measurements of SR.sub.L are obtained immediately after antigen challenge and at 1, 2, 3, 4, 5, 6, 6.5, 7, 7.5, and 8 hrs after antigen challange. 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 hrs after Ascaris as described above.

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