Method of treating gout with certain indole compounds

This invention relates to the use of tryptophan derivatives as inhibitors of neutrophil mediated oxidant production and their use in treating neutrophil associated diseases and disorders.

Neutrophils play a vital role in the resistance of a host to infection. Key characteristics of neutrophils in this role include their ability to adhere initially to the endothelium, to migrate into tissue, and to kill engulfed microbes with oxidants and proteolytic enzymes. Unfortunately, in certain disease states, neutrophils secrete these oxidants and proteolytic enzymes extracellularly resulting in inflammatory diseases and conditions.

The compounds of the present invention have been shown to effectively inhibit adhesion-dependent oxidant production. Accordingly, this invention provides methods of treating disease and conditions associated with excess neutrophil mediated oxidant production, including the following inflammatory diseases and other conditions: smoking, chronic bronchitis, emphysema, asthma, cystic fibrosis, cancer, adult respiratory distress syndrome, Wegener's granulomatosis, idiopathic pulmonary fibrosis, collagen vascular disorders, interstitial lung disease, hypersensitivity pneumonitis, sarcoidosis, bronchiolitis obliterans with organizing pneumonia, Crohn's Disease, Secondary Sjörgren's Syndrome, rheumatoid arthritis, progressive systemic sclerosis, dermatopolymyositis, mixed connective tissue disease, familial idiopathic pulmonary fibrosis, systemic lupus erythematosus, progressive systemic sclerosis, autoimmune thyroid disease, inflammatory bowel disease, juvenile periodontitis, myocardial infarction, hemorrhagic shock, septic shock, ischemic shock, cerebral ischemia, stroke, hypertension, unstable angina, diabetes complications, thrombotic stroke, fibrosing alveolitis, bronchiectasis, periodontal disease, glomerulonephritis, alcoholic hepatitis, Kawasaki Disease, gingivitis, chronic obstructive pulmonary disease, pulmonary infections (staphylococcal or klebsiella pneumonia), ulcerative colitis, psoriasis, artherosclerosis, gout, gastroesophageal reflux disease, carditis, Barrett's Esophagus, Behcet's Disease, iritis, acute glomerulonephritis, periarteritis nodosa, unstable angina, coronary artery disease, coronary angioplasty, immune complex disease, cryoglobulinemic glomerulonephritis, anti-gbm glomerulonephritis, Goodpasture's Syndrome, myositis, and acute pancreatitis.

The invention provides a method for inhibiting neutrophil mediated oxidant production, comprising administering to a mammal in need thereof, a pharmaceutically effective amount of a compound of the formula I:

The species of amino-protecting group employed is usually not critical so long as the derivatized amino group is stable to the condition of subsequent reactions on other positions of the intermediate molecule and can be selectively removed at the appropriate point without disrupting the remainder of the molecule including any other amino-protecting groups. Preferred amino-protecting groups are trityl, t-butoxycarbonyl (t-BOC), allyloxycarbonyl and benzyloxycarbonyl. Further examples of groups referred to by the above terms are described by E. Haslam, “Protective Groups in Organic Chemistry”, (J. G. W. McOmie, ed., 1973), at Chapter 2; and T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis” (1991), at Chapter 7.

The term “carboxy-protecting group” as used in the specification refers to substituents of the carboxy group commonly employed to block or protect the carboxy functionality while reacting other functional groups on the compound. Examples of such carboxy-protecting groups include methyl, p-nitrobenzyl, p-methylbenzyl, p-methoxybenzyl, 3,4-dimethoxybenzyl, 2,4-dimethoxybenzyl, 2,4,6-trimethoxybenzyl, 2,4,6-trimethylbenzyl, pentamethylbenzyl, 3,4-methylene-dioxybenzyl, benzhydryl, 4,4′-dimethoxybenzhydryl, 2,2′, 4,4′-tetramethoxybenzhydryl, t-butyl, t-amyl, trityl, 4-methoxytrityl, 4,4′-dimethoxytrityl, 4,4′, 4″-trimethoxytrityl, 2-phenylprop-2-yl, trimethylsilyl, t-butyldimethylsilyl, phenacyl, 2,2,2-trichloroethyl, 2-(di(n-butyl)methylsilyl)ethyl, p-toluenesulfonylethyl, 4-nitrobenzylsulfonylethyl, allyl, cinnamyl, 1-(trimethylsilylmethyl)prop-1-en-3-yl and like moieties. Preferred carboxy-protecting groups are allyl, benzyl and t-butyl. Further examples of these groups are found in E. Haslam, supra, at Chapter 5, and T. W. Greene, et al., supra, at Chapter 5.

The term “leaving group” as used herein refers to a group of atoms that is displaced from a carbon atom by the attack of a nucleophile in a nucleophilic substitution reaction. The term “leaving group” as used in this document encompasses, but is not limited to, activating groups.

The term “activating group” as used herein refers a leaving group which, when taken with the carbonyl (—C═O) group to which it is attached, is more likely to take part in an acylation reaction than would be the case if the group were not present, as in the free acid. Such activating groups are well-known to those skilled in the art and may be, for example, succinimidoxy, phthalimidoxy, benzotriazolyloxy, benzenesulfonyloxy, methanesulfonyloxy, toluenesulfonyloxy, azido, or —O—CO—(C

alkyl).

The compounds used in the methods of the present invention have multiple asymmetric centers. As a consequence of these chiral centers, the compounds occur as racemates, mixtures of enantiomers and as individual enantiomers, as well as diastereomers and mixtures of diastereomers. All asymmetric forms, individual isomers and combinations thereof, are within the scope of the present invention.

The terms “R” and “S” are used herein as commonly used in organic chemistry to denote specific configuration of a chiral center. The term “R” (rectus) refers to that configuration of a chiral center with a clockwise relationship of group priorities (highest to second lowest) when viewed along the bond toward the lowest priority group. The term “S” (sinister) refers to that configuration of a chiral center with a counterclockwise relationship of group priorities (highest to second lowest) when viewed along the bond toward the lowest priority group. The priority of groups is based upon their atomic number (in order of decreasing atomic number). A partial list of priorities and a discussion of stereochemistry is contained in “Nomenclature of Organic Compounds: Principles and Practice”, (J. H. Fletcher, et al., eds., 1974) at pages 103-120.

In addition to the (R)-(S) system, the older D-L system is also used in this document to denote absolute configuration, especially with reference to amino acids. In this system a Fischer projection formula is oriented so that the number 1 carbon of the main chain is at the top. The prefix “D” is used to represent the absolute configuration of the isomer in which the functional (determining) group is on the right side of the carbon atom at the chiral center and “L”, that of the isomer in which it is on the left.

As noted suora, this invention includes the use of pharmaceutically acceptable salts of the compounds defined by Formula I. A compound of formula I can possess a sufficiently acidic, a sufficiently basic, or both functional groups, and accordingly react with any of a number of organic and inorganic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt.

The term “pharmaceutically acceptable salt” as used herein, refers to salts of the compounds of the above formula which are substantially non-toxic to living organisms. Typical pharmaceutically acceptable salts include those salts prepared by reaction of the compounds of the present invention with a pharmaceutically acceptable mineral or organic acid or an organic or inorganic base. Such salts are known as acid addition and base addition salts.

Acids commonly employed to form acid addition salts are inorganic acids such as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, and the like, and organic acids such as p-toluenesulfonic, methanesulfonic acid, oxalic acid, p-bromophenylsulfonic acid, carbonic acid, succinic acid, citric acid, benzoic acid, acetic acid, and the like. Examples of such pharmaceutically acceptable salts are the sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, bromide, iodide, acetate, propionate, decanoate, caprylate, acrylate, formate, hydrochloride, dihydrochloride, isobutyrate, caproate, heptanoate, propiolate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, butyne-1,4-dioate, hexyne-1,6-dioate, benzoate, chlorobenzoate, methylbenzoate, hydroxybenzoate, methoxybenzoate, phthalate, xylenesulfonate, phenylacetate, phenylpropionate, phenylbutyrate, citrate, lactate, γ-hydroxybutyrate, glycolate, tartrate, methanesulfonate, propanesulfonate, naphthalene-1-sulfonate, napththalene-2-sulfonate, mandelate and the like. Preferred pharmaceutically acceptable acid addition salts are those formed with mineral acids such as hydrochloric acid and hydrobromic acid, and those formed with organic acids such as maleic acid and methanesulfonic acid.

Base addition salts include those derived from inorganic bases, such as ammonium or alkali or alkaline earth metal hydroxides, carbonates, bicarbonates, and the like. Such bases useful in preparing the salts of this invention thus include sodium hydroxide, potassium hydroxide, ammonium hydroxide, potassium carbonate, sodium carbonate, sodium bicarbonate, potassium bicarbonate, calcium hydroxide, calcium carbonate, and the like. The potassium and sodium salt forms are particularly preferred.

It should be recognized that the particular counterion forming a part of any salt of this invention is usually not of a critical nature, so long as the salt as a whole is pharmacologically acceptable and as long as the counterion does not contribute undesired qualities to the salt as a whole.

This invention further encompasses the use of pharmaceutically acceptable solvates of the compounds of Formula I. Many of the Formula I compounds can combine with solvents such as water, methanol, ethanol and acetonitrile to form pharmaceutically acceptable solvates such as the corresponding hydrate, methanolate, ethanolate and acetonitrilate.

The compounds employed in the present invention can be prepared by a variety of procedures well known to those of ordinary skill in the art. The particular order of steps required to produce the compounds of Formula I is dependent upon the particular compound being synthesized, the starting compound, and the relative lability of the substituted moieties.

Examples of such protocols are depicted in Schemes I through IV. The coupling of the substituted amine to the compound of Formula II (Method A) can be performed by many means known in the art, the particular methods employed being dependent upon the particular compound of Formula II which is used as the starting material and the type of substituted amine used in the coupling reaction. These coupling reactions frequently employ commonly used coupling reagents such as 1,1-carbonyl diimidazole, dicyclohexylcarbodiimide, diethyl azodicarboxylate, 1-hydroxybenzotriazole, alkyl chloroformate and triethylamine, phenyldichlorophosphate, and chlorosulfonyl isocyanate. Examples of these methods are described infra. After deprotection of the amino group, the compounds of Formula III are obtained.

The compound of Formula III is then reduced, converting the amide into an amine (Method B). Amides can be reduced to amines using procedures well known in the art. These reductions can be performed using lithium aluminum hydride as well as by use of many other different aluminum-based hydrides. Alternatively, the amides can be reduced by catalytic hydrogenation, though high temperatures and pressures are usually required for this. Sodium borohydride in combination with other reagents may be used to reduce the amide. Borane complexes, such as a borane dimethylsulfide complex, are especially useful in this reduction reaction.

The next step in Scheme I (Method C) is the selective acylation of the primary amine using standard methods, as typified by Method C. Because of the higher steric demand of the secondary amine, the primary amine is readily available for selective substitution.

This acylation can be done using any of a large number of techniques regularly employed by those skilled in organic chemistry. One such reaction scheme is a substitution using an anhydride such as acetic anhydride. Another reaction scheme often employed to acylate a primary amine employs a carboxylic acid preferably with an activating agent as described for Method A, supra. An amino-de-alkoxylation type of reaction uses esters as a means of acylating the primary amine. Activated esters which are attenuated to provide enhanced selectivity are very efficient acylating agents.

Primary amines can also be acylated using amides to perform what is essentially an exchange reaction. This reaction is usually carried out with the salt of the amine. Boron trifluoride, usually in the form of a boron trifluoride diethyl ether complex, is frequently added to this reaction to complex with the leaving ammonia.

The next procedure is one of substitution of the secondary amine (Method D). For most of the compounds of Formula I this substitution is one of alkylation, acylation, or sulfonation. This substitution is usually accomplished using well recognized means. Typically, alkylations can be achieved using alkyl halides and the like as well as the well-known reductive alkylation methods as seen in Method G, Scheme II, supra, employing aldehydes or ketones. Many of the acylating reaction protocols discussed suora efficiently acylate the secondary amine as well. Alkyl- and aryl-sulfonyl chlorides can be employed to sulfonate the secondary amine.

In many instances one of the later steps in the synthesis of the compounds of Formula I is the removal of an amino- or carboxy-protecting group. Such procedures, which vary, depending upon the type of protecting group employed as well as the relative lability of other moieties on the compound, are described in detail in many standard references works such as T. W. Greene, et al., Protective Groups in Organic Synthesis (1991).

Schemes II and III depict alternative protocols and strategies for the synthesis of the compounds of Formula I. Many of the individual reactions are similar to those described in Scheme I but the reactions of Schemes II and III are done in a different, but yet well known to those skilled in the art, series of steps.

In order to preferentially prepare one optical isomer over its enantiomer, the skilled practitioner can proceed by one of two routes. The practitioner may first prepare the mixture of enantiomers and then separate the two enantiomers. A commonly employed method for the resolution of the racemic mixture (or mixture of enantiomers) into the individual enantiomers is to first convert the enantiomers to diastereomers by way of forming a salt with an optically active salt or base. These diastereomers can then be separated using differential solubility, fractional crystallization, chromatography, or like methods. Further details regarding resolution of enantiomeric mixtures can be found in J. Jacques, et al., “Enantiomers, Racemates, and Resolutions”, (1991).

In addition to the schemes described above, the practitioner of this invention may also choose an enantiospecific protocol for the preparation of the compounds of Formula I. Scheme IV, infra, depicts a typical such synthetic reaction design which maintains the chiral center present in the starting material in a desired orientation, in this case in the “R” configuration. These reaction schemes usually produce compounds in which greater than 95 percent of the title product is the desired enantiomer.

Many of the synthetic steps employed in Scheme IV are the same as used in other schemes, especially Scheme III.

The following depicts representative examples of reaction conditions employed in the preparation of the compounds of Formula I.

This mixture was continuously stirred for 4.25 hours. Triethylamine (147.0 ml, 1.055 moles) was added followed by the addition of a solution of triphenylmethyl chloride (147.0 g, 0.552 mole) in methylene chloride (400 ml) using an addition funnel. The mixture was stirred at room temperature, under a nitrogen atmosphere for at least 20 hours. The reaction was quenched by the addition of methanol (500 ml).

The solution was concentrated on a rotary evaporator to near dryness and the mixture was redissolved in methylene chloride and ethyl acetate. An aqueous work-up involving a 5% citric acid solution (2×) and brine (2×) was then performed. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated to dryness on a rotary evaporator.

After 4 hours, the reaction mixture was concentrated to an oil on a rotary evaporator and redissolved in diethyl ether and 1.0 N hydrochloric acid. The aqueous layer was washed twice with diethyl ether and basified with sodium hydroxide to a pH greater than 12. The product was extracted out with methylene chloride (4×). The organic extracts were combined, dried over anhydrous sodium sulfate, filtered, and concentrated on a rotary evaporator to a white foam. The compound 2-amino-3-(1H-indol-3-yl)-1-[N-(2-methoxybenzyl)acetylamino]propane (7.52 g, 21.397 mmols) was isolated giving a 90% yield. No further purification was necessary.

METHOD M

Bromoacetylation

Preparation of 2-[(2-bromo)acetyl]amino-3-(1H-indol-3-yl)-1-[N-(2-methoxybenzyl)acetylamino]propane

To a stirring solution of 2-amino-3-(1H-indol-3-yl)-1-[N-(2-methoxybenzyl)acetylamino]propane (7.51 g, 21.369 mmoles) in anhydrous tetrahydrofuran (100 ml) under a nitrogen atmosphere at 0° C. was added diisopropylethylamine (4.1 ml, 23.537 mmoles) and bromoacetyl bromide (2.05 ml, 23.530 mmoles). After 2 hours, ethyl acetate was added and the reaction mixture washed with water twice, 1.0 N hydrochloric acid (2×), saturated sodium bicarbonate solution (2×), and brine. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated to a tan foam on a rotary evaporator. In this manner the 2-[(2-bromo)acetyl]amino-3-(1H-indol-3-yl)1-[N-(2-methoxybenzyl)acetylamino]propane was obtained in quantitative yield. No further purification was necessary.

METHOD N

Nucleophilic Displacement

Preparation of 1-[N-(2-methoxybenzyl)acetylamino]-3-(1H-indol-3-yl)-2-[N-(2-((4-cyclohexyl)piperazin-1-yl)acetyl)amino]propane

1-Cyclohexylpiperazine (3.65 g, 22.492 mmoles) was added to a stirring solution of 2-[(2-bromo)acetyl]amino-3-(1H-indol-3-yl)-1-[N-(2-methoxybenzyl)acetylamino]propane (21.369 mmoles) and powdered potassium carbonate (3.56 g, 25.758 mmols) in methylene chloride under a nitrogen atmosphere. The reaction mixture was stirred overnight at room temperature. The salts were filtered and the solution concentrated to a brown foam on a rotary evaporator. The desired product was purified on a Prep 500 column using a 10 L gradient starting with 100% methylene chloride and ending with 5% methanol/94.5% methylene chloride/0.5% ammonium hydroxide. Impure fractions were combined and purified further by reverse phase preparative high performance liquid chromatography (methanol/acetonitrile/water/ammonium acetate). After combining the material from both chromatographic purifications the title compound (10.43 g, 18.663 mmoles) was isolated (87% yield).

An alternative means of acylation of the primary amine as shown in the final step of the synthesis protocol of Scheme IV is by means of reacting a compound of the formula

with a potassium carboxylate of the formula

in the presence of isobutylchloroformate and N-methylmorpholine. This reaction is usually performed in the presence of a non-reactive solvent such as methylene chloride at cool temperatures, usually between −30° C. and 10° C., more preferably at temperatures between −20° C. and 0° C. In this reaction equimolar amounts of the two reactants are generally employed although other ratios are operable. An example of this preferred means of acylating the primary amine is shown in the following example.

METHOD P

Preparation of (R)-1-[N-(2-methoxybenzyl)acetylamino]-3-(1H-indol-3-yl)-2-[N-(2-((4-cyclohexyl)piperazin-1-yl)acetyl)amino]propane

The title compound was prepared by first cooling 2-((4-cyclohexyl)piperazin-1-yl)acetic acid potassium salt to a temperature between −8° C. and −15° C. in 5 volumes of anhydrous methylene chloride. To this mixture was then added isobutylchloroformate at a rate such that the temperature did not exceed −8° C. This reaction mixture was then stirred for about 1 hour, the temperature being maintained between −8° C. and −15° C.

To this mixture was then added (R)-2-amino-3-(1H-indol-3-yl)-1-[N-(2-methoxybenzyl)acetylamino]propane dihydrochloride at such a rate that the temperature did not exceed 0° C. Next added to this mixture was N-methyl morpholine at a rate such that the temperature did not exceed 0° C. This mixture was then stirred for about 1 hour at a temperature between −15° C. and −8° C.

The reaction was quenched by the addition of 5 volumes of water. The organic layer was washed once with a saturated sodium bicarbonate solution. The organic phase was then dried over anhydrous potassium carbonate and filtered to remove the drying agent. To the filtrate was then added 2 equivalents of concentrated hydrochloric acid, followed by 1 volume of isopropyl alcohol. The methylene chloride was then exchanged with isopropyl alcohol under vacuum by distillation.

The final volume of isopropyl alcohol was then concentrated to three volumes by vacuum. The reaction mixture was cooled to 20° C. to 25° C. and the product was allowed to crystallize for at least one hour. The desired product was then recovered by filtration and washed with sufficient isopropyl alcohol to give a colorless filtrate. The crystal cake was then dried under vacuum at 50° C.

The following table illustrates many of the compounds produced using essentially the steps described in Schemes I through IV. A person of ordinary skill in the art would readily understand that a certain order of steps must be employed in many instances to avoid reactions other than the one sought. For example, as in the above methods, it is frequently necessary to employ a protecting group in order to block a reaction at a particular moiety.

The abbreviations used in the following table are commonly used in the field and would be readily understood by a practitioner in the field. For example, the abbreviation “Ph” refers to a phenyl group, “i-Pr” refers to an isopropyl group, “Me” describes a methyl group, “Et” refers to an ethyl group, “t-Bu” describes a tert-butyl group, and the like.

In the following table, the first column gives the example number of the compound. The next columns (may be one, two, or three columns) describe the substitution patterns of the particular example. The column entitled “Mp° C. ” gives the melting point of the compound if it is a solid or notes the form of the substance at ambient temperature. The next column, entitled “MS”, defines the mass of the compound as determined by mass spectroscopy. The following column gives the nuclear magnetic resonance profile of the example compound as synthesized. The final columns give the molecular formula of the example compound as well as its elemental analysis.

The compounds of formula I are potent effective inhibitors of neutrophil mediated oxidant production. As such, they are useful in treating conditions associated with excessive or unregulated neutrophil accumulation, such as, but not limited to, the following: smoking, chronic bronchitis, emphysema, asthma, cystic fibrosis, cancer, adult respiratory distress syndrome, Wegener's granulomatosis, idiopathic pulmonary fibrosis, collagen vascular disorders, interstitial lung disease, hypersensitivity pneumonitis: sarcoidosis, bronchiolitis obliterans with organizing pneumonia, Crohn's Disease, Secondary Sjörgren's Syndrome, rheumatoid arthritis, progressive systemic sclerosis, dermatopolymyositis, mixed connective tissue disease, familial idiopathic pulmonary fibrosis, systemic lupus erythematosus, progressive systemic sclerosis, autoimmune thyroid disease, inflammatory bowel disease, juvenile periodontitis, myocardial infarction, hemorrhagic schock, septic shock, ischemic shock, cerebral ischemia, stroke, hypertension, unstable angina, diabetes complications, thrombotic stroke, fibrosing alveolitis, bronchiectasis, periodontal disease, glomerulonephritis, alcoholic hepatitis, Kawasaki Disease, gingivitis, chronic obstructive pulmonary disease, pulmonary infections (staphylococcal or klebsiella pneumonia), ulcerative colitis, psoriasis, artherosclerosis, gout, gastroesophageal reflux disease, carditis, Barrett's Esophagus, Behcet's Disease, iritis, acute glomerulonephritis, periarteritis nodosa, unstable angina, coronary artery disease, coronary angioplasty, immune complex disease, cryoglobulinemic glomerulonephritis, anti-gbm glomerulonephritis, Goodpasture's Syndrome, myositis, and acute pancreatitis.

It is known that excess accumulation of neutrophils may lead to release of toxic oxygen radicals that potentiate tissue damage. Accordingly, representative compounds of the formula I were evaluated and found to effectively inhibit adhesion dependent oxidant production in the Inhibition of Adhesion-Dependent Oxidant Production test system described below.

Isolation of Human Neutrophils

Venous blood was drawn from healthy donors into citrate-phosphate dextrose anti-coagulant. Five ml of the collected blood were mixed with 1.5 ml 6% dextran in 0.87% NaCl solution (Macrodex®) and incubated at 37° C. for 25-35 minutes until the erythrocytes agglutinated and settled to the bottom of the tube. The supernatant fluid was removed and centrifuged at room temperature for 5 minutes at 300 g. The resulting cell pellet was resuspended in a volume of Dulbeccol's phosphate buffered saline (PBS) containing 0.2% glucose that was equal to the original blood volume. In 10 ml portions, the suspension was layered over 5 ml of Ficoll-Paque® and centrifuged at room temperature for 20 minutes at 675 g. All of the supernatant fluid and the resulting mononuclear cell layer were carefully removed and discarded. The pellet was resuspended as above, the cell density determined with a Cell-Dyne 1600 and the suspension centrifuged at 300 g for 5 minutes. The differential white blood cell (WBC) count was >90% granulocytes. After discarding the supernatant fluid, the cell pellet was resuspended as above at 1 million granulocytes/ml and used promptly in the assay.

Inhibition of Adhesion-Denendent Oxidant Production

Compounds were evaluated for their ability to inhibit hydrogen peroxide produced by neutrophils after the cells had been stimulated with formyl-L-methionyl-L-leucyl-L-phenylalanine (fMLP) to adhere and spread on a keyhole limpet hemocyanin (KLH)-coated surface. The amount of peroxide produced was measured by reacting it enzymatically with the fluorescent substrate, scopoletin. The reaction was carried out in 96-well plates using a protocol very similar to that reported by Shappell et al.,

J. Immunol.,

144, 2702-2711 (1990). Tissue culture plates (Linbro/ICN Flow) were prepared by filling each well with 250 μl of a filtered solution of 0.5 mg/ml KLH in carbonate-bicarbonate buffer containing 0.02% sodium azide. Plates were tightly sealed, incubated at 37° C. for 2-18 hours and then stored at 4° C. for up to 6 weeks. Just prior to being used, plates were washed twice with 250 μl Dulbecco's PBS per well and patted dry. All reagents were dissolved in a Krebs-Ringer-Phosphate (KRP) buffer containing 0.1% glucose, pH 7.35, 145 mM NaCl, 4.86 mM KCl, 0.54 mM CaCl

, 1.22 mM MgSO

, and 5.77 mM Na

. Compounds were initially dissolved in dimethyl sulfoxide (DMSO) at 50 mM and stored at 4° C. until used. Appropriate dilutions were made with the KRP buffer to yield working solutions containing 0.2% DMSO. To start the reaction, wells were initially filled with 100 μl of buffer containing 0.2% DMSO or appropriate stock inhibitor solution. Next, 25 μl of fluorescent indicator mixture containing 5.6 mM sodium azide, 136 μM scopoletin and 28.8 μg/ml of horseradish peroxidase was added to each well. Then 25 μl of 240 nM fMLP in PBS was dispensed into the wells. The reaction was started by adding 50 μl of cell suspension (1×10

6

cells per ml). All experiments were carried out at 37° C. Spontaneous oxidation of scopoletin was monitored by observing the loss of fluorescence in wells to which no cells had been added. Fluorescence readings were made with either a Millipore Cytofluor 2350 or PerSeptive Biosystems Cytofluor II using an excitation wavelength of 360 nm and an emission wavelength of 460 nm. Inhibition concentration studies were carried out by testing five, 3-fold dilutions of each compound. After a lag period of 15-30 minutes, cells stimulated in the absence of any inhibitor began to produce H

and the fluorescence decreased rapidly for the next 30-45 minutes. The time points that bracketed the steepest drop in fluorescence of these positive control wells were used to determine the extent of reaction in all wells. The fluorescence decrease (f.d.) during this time period at all compound concentrations was measured and the percent inhibition determined with the following formula:

100 \times \frac{\begin{matrix} (f . d . of positive control - \\ f . d . of compound - treated cells) \end{matrix}}{\begin{matrix} (f . d . of positive control - \\ f . d . of no cells control) \end{matrix}}

The IC

value was calculated assuming a linear relationship between percent inhibition and compound concentration in the region between 25% and 75% inhibition.

The compounds of Formula I are usually administered in the form of pharmaceutical compositions. These compounds can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular, and intranasal. These compounds are effective as both injectable and oral compositions. Such compositions are prepared in a manner well known in the pharmaceutical art and comprise at least one active compound.

The active compound is effective over a wide dosage range. For example, dosages per day normally fall within the range of about 0.5 to about 30 mg/kg of body weight. In the treatment of adult humans, the range of about 1 to about 15 mg/kg/day, in single or divided doses, is especially preferred. However, it will be understood that the amount of the compound actually administered will be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, and the severity of the patient's symptoms, and therefore the above dosage ranges are not intended to limit the scope of the invention in any way. In some instances dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effect, provided that such larger doses are first divided into several smaller doses for administration throughout the day.
