Description

WO 97/16442 PCT/US96/18539 -1- TITLE OF THE INVENTION SUBSTITUTED PYRIDYL PYRROLES, COMPOSITIONS CONTAINING SUCH COMPOUNDS AND METHODS OF USE BACKGROUND OF THE INVENTION The present invention relates to pyridyl substituted pyrroles. This invention also relates to compositions containing such compounds and methods of treatment.

Diabetes is a disease process derived from multiple causative factors and characterized by elevated levels of plasma glucose.

Uncontrolled hyperglycemia is associated with an increased risk for microvascular and macrovascular diseases, including nephropathy, retinopathy, hypertension, stroke and heart disease. Control of glucose levels is, therefore, a major approach to the treatment of diabetes.

Glucagon is a major counter regulatory hormone that attenuates the inhibition of liver gluconeogenesis by insulin. Glucagon receptors are found primarily in the liver, although their presence has been documented in kidney and adipose tissue.

Type II diabetics have elevated levels of plasma glucagon and increased rates of hepatic glucose production. The rate of hepatic glucose production positively correlates with fasting blood glucose levels in type II diabetics. Therefore, antagonists of glucagon are useful in improving insulin responsiveness in the liver, decreasing the rate of gluconeogenesis and lowering the rate of hepatic glucose output resulting in a decrease in the levels of plasma glucose.

Blood glucose homeostasis is also mediated by the hormone insulin, produced in the P cells of the pancreas. Deterioration of these cells is typically observed in Type I diabetics, and abnormalities in the function of these cells may occur in patients presenting the symptoms of Type II diabetes.

Cytokine mediated diseases refers to diseases or conditions in which excessive or unregulated production or activity of one or more cytokines occurs. Interleukin-1 Interleukin-6 (IL-6), Interleukin-8 (IL-8) and Tumor Necrosis Factor (TNF) are cytokines WO 97/16442 PCT/US96/18539 -2produced by a variety of cells, which are involved in immunoregulation and other physiological conditions, such as inflammation.

IL-1 has been demonstrated to mediate a variety of biological activities thought to be important in immunoregulation and other physiological conditions. [See, Dinarello et al., Rev. Infect.

Disease, 6, 51 (1984)]. The myriad of known biological activities of IL-1 include the activation of T-helper cells, induction of fever, stimulation of prostaglandin or collagenase production, neutrophil chemotaxis, induction of acute phase proteins and the suppression of plasma iron levels.

There are many disease states in which IL-1 is implicated.

Included among these diseases are rheumatoid arthritis, osteoarthritis, endotoxemia, toxic shock syndrome, other acute or chronic inflammatory diseases, such as the inflammatory reaction induced by endotoxin or inflammatory bowel disease; tuberculosis, atherosclerosis, muscle degeneration, cachexia, psoriatic arthritis, Reiter's syndrome, rheumatoid arthritis, gout, traumatic arthritis, rubella arthritis and acute synovitis. Recent evidence also links IL-1 activity to diabetes and pancreatic 3 cells.

IL-6 is a cytokine effecting the immune system, hematopoiesis and acute phase reactions. It is produced by several mammalian cell types in response to agents such as IL-1 and is correlated with disease states such as angiofollicular lymphoid hyperplasia.

IL-8 is a chemotactic factor first identified and characterized in 1987. Many different names have been applied to IL-8, such as neutrophil attractant/activation protein-1 (NAP-1), monocyte derived neutrophil chemotactic factor (MDNCF), neutrophil activating factor (NAF), and T-cell lymphocyte chemotactic factor.

Like IL-1, IL-8 is produced by several cell types, including mononuclear cells, fibroblasts, and endothelial cells. Its production is induced by IL-1, TNF and by lipopolysaccharide (LPS). IL-8 stimulates a number of cellular functions in vitro. It is a chemoattractant for neutrophils, T-lymphocytes and basophils. It induces histamine release WO 97/16442 PCT/US96/18539 -3 from basophils. It causes lysozomal enzyme release and respiratory burst from neutrophils, and it has been shown to increase the surface expression of Mac-1 (CD1 lb/CD 18) on neutrophils without de novo protein synthesis. The compounds of formula I are also useful in treating diseases characterized by excessive IL-8 activity. There are many disease states in which excessive or unregulated IL-8 production is implicated in exacerbating and/or causing the disease. These diseases include psoriasis, inflammatory bowel disease, asthma, cardiac and renal reperfusion injury, adult respiratory distress syndrome, thrombosis and glomerulonephritis.

Excessive or unregulated TNF production has been implicated in mediating or exacerbating rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions; sepsis, septic shock, endotoxic shock, gram negative sepsis, toxic shock syndrome, adult respiratory distress syndrome, cerebral malaria, chronic pulmonary inflammatory disease, silicosis, pulmonary sarcosis, bone resorption diseases, reperfusion injury, graft v. host reaction, allograft rejections, fever and myalgias due to infection, such as influenza, cachexia secondary to infection or malignancy, cachexia secondary to acquired immune deficiency syndrome (AIDS), AIDS related complex (ARC), keloid formation, scar tissue formation, Crohn's disease, ulcerative colitis and pyresis.

Cytokines, such as TNF, have been shown to activate HIV replication in monocytes and/or macrophages [See Poli, et al., Proc.

Natl. Acad. Sci., 87:782-784 (1990)]. Therefore, inhibition of monokine production or activity aids in limiting HIV progression as stated above for T-cells. TNF has also been implicated in various roles with other viral infections, such as the cytomegalovirus

(CMV),

influenza virus and the herpes virus.

There remains a need for compounds which are cytokine suppressive or antagonistic, compounds which are capable of interfering with, inhibiting or antagonizing cytokines such as IL-1, IL- 6, IL-8 and TNF.

Also included in the invention is a method of treating cytokine mediated disease in a mammal, comprising administering to a mammalian patient in need of such treatment an amount of a compound of formula I which is effective to treat said cytokine mediated disease.

DETAILED DESCRIPTION OF THE INVENTION The invention is described herein in detail using the terms defined below unless otherwise specified.

The term "alkyl" refers to a monovalent alkane (hydrocarbon) derived radical containing from 1 to 15 carbon atoms unless otherwise defined. It may be straight, branched or cyclic. Preferred straight or branched alkyl groups include methyl, ethyl, propyl, isopropyl, butyl and t-butyl. Preferred cycloalkyl groups include cyclopentyl and cyclohexyl.

Alkyl also includes a straight or branched alkyl group which contains or is interrupted by a cycloalkylene portion. Examples include the following:

(CH

2 )x -I (CH 2 )y and w (C H 2 )z wherein: x plus y from 0-10 and w plus z from 0-9.

The alkylene and monovalent alkyl portion(s) of the alkyl group can be attached at any available point of attachment to the cycloalkylene portion.

When substituted, alkyl groups may be substituted with up to three substituent groups, as defined, at any available point of attachment. One of the 15 carbon atoms can be carbonyl. Thus, substitution may be in the straight or branched portion, or in the cycloalkyl portion.

WO 97/16442 PCT/US96/18539 -9- The term "alkenyl" refers to a hydrocarbon radical straight, branched or cyclic containing from 2 to 15 carbon atoms and at least one carbon to carbon double bond. Preferably one carbon to carbon double bond is present, and up to four non-aromatic (nonresonating) carbon-carbon double bonds may be present. Preferred alkenyl groups include ethenyl, propenyl, butenyl and cyclohexenyl. As described above with respect to alkyl, the straight, branched or cyclic portion of the alkenyl group may contain double bonds and may be substituted when a substituted alkenyl group is provided.

The term "alkynyl" refers to a hydrocarbon radical straight, branched or cyclic, containing from 2 to 15 carbon atoms and at least one carbon to carbon triple bond. Up to three carbon-carbon triple bonds may be present. Preferred alkynyl groups include ethynyl, propynyl and butynyl. As described above with respect to alkyl, the straight, branched or cyclic portion of the alkynyl group may contain triple bonds and may be substituted when a substituted alkynyl group is provided.

Aryl refers to aromatic rings phenyl, substituted phenyl and like groups as well as rings which are fused, naphthyl and the like. Aryl thus contains at least one ring having at least 6 atoms, with up to two such rings being present, containing up to 10 atoms therein, with alternating (resonating) double bonds between adjacent carbon atoms. The preferred aryl groups are phenyl and naphthyl.

Aryl groups may likewise be substituted with 1-3 groups selected from Ra. Preferred substituted aryls include phenyl and naphthyl substituted with one or two groups.

The term "heteroaryl" refers to a monocyclic aromatic hydrocarbon group having 5 or 6 ring atoms, or a bicyclic aromatic group having 8 to 10 atoms, containing at least one heteroatom, 0, S or N, in which a carbon or nitrogen atom is the point of attachment, and in which one additional carbon atom is optionally replaced by a heteroatom selected from O or S, and/or in which from 1 to 3 additional carbon atoms are optionally replaced by nitrogen heteroatoms. The heteroaryl WO 97/16442 PCT/US96/1853 9 10 group is optionally substituted with up to three groups selected from Ra.

Heteroaryl thus includes aromatic and partially aromatic groups which contain one or more heteroatoms. Examples of this type are pyrrole, furan, thiophene, pyridine, oxazole, thiazole and oxazine.

Additional nitrogen atoms may be present together with the first nitrogen and oxygen or sulfur, giving, thiadiazole. The preferred heteroaryls are those where only nitrogen heteroatoms are present when there is more than one. Typical of these are pyrazole, tetrazole, imidazole, pyridine, pyrimidine and pyrazine.

The group represents a heteroaryl group which contains from 5 to 10 atoms. One to four atoms are heteroatoms which are selected from O, S and N. The heteroaryl group may be unsubstituted or substituted with 0-3 Ra groups.

Preferred heteroaryl groups represented by are as follows: pyridyl, quinolyl, purinyl, imidazolyl, imidazopyridinyl and pyrimidinyl.

The terms "heterocycloalkyl" and "heterocyclyl" refer to a cycloalkyl group (nonaromatic) in which one of the carbon atoms in the ring is replaced by a heteroatom selected from O, S or N, and in which up to three additional carbon atoms may be replaced by heteroatoms.

The heterocyclyl is carbon or nitrogen linked, if said heterocyclyl is carbon linked and contains a nitrogen, then nitrogen may be substituted by R 2 4 One of the carbon atoms can be carbonyl.

Examples of heterocyclyls are piperidinyl, morpholinyl, pyrrolidinyl, tetrahydrofuranyl, tetrahydroimidazo[4,5-c]pyridine, imidazolinyl, piperazinyl, pyrolidine-2-one, piperidin-2-one and the like.

Oxo refers to carbonyl groups The term "TNF mediated disease or disease state" refer to disease states in which TNF plays a role, either by production of TNF itself, or by TNF causing another monokine to be released, such as but not limited to IL-I or IL-6. A disease state in which IL-1, for instance WO 97/16442 PCT/US96/18539 11 is a major component, and whose production or action, is exacerbated or secreted in response to TNF, would therefore be considered a disease state mediated by TNF.

The term "cytokine" as used herein is meant any secreted polypeptide that affects the functions of cells and is a molecule which modulates interactions between cells in the immune, inflammatory or hematopoietic response. A cytokine includes, but is not limited to, monokines and lymphokines regardless of which cells produce them.

Examples of cytokines include, but are not limited to, Interleukin-1 Interleukin-6 Tumor Necrosis Factor-alpha (TNF-ca) and Tumor Necrosis Factor-beta (TNF-p).

By the term "cytokine antagonizing, interfering or cytokine suppressive amount" is meant an amount of a compound of formula I which will, cause a decrease in the in vivo presence or level of the cytokine to normal or sub-normal levels, when given to the patient for the prophylaxis or therapeutic treatment of a disease state which is exacerbated by, or caused by, excessive or unregulated cytokine production.

The compounds of the present invention may contain one or more asymmetric carbon atoms and may exist in racemic and optically active forms. All of these compounds are contemplated to be within the scope of the present invention.

Throughout the instant application, the following abbreviations are used with the following meanings: aFGF acid fibroblast growth factor Bu butyl Bn benzyl BOC, Boc t-butyloxycarbonyl CBZ, Cbz Benzyloxycarbonyl DCC Dicyclohexylcarbodiimide DCM dichloromethane DIEA diisopropylethylamine DMF N,N-dimethylformamide DMAP 4 -Dimethylaminopyridine WO 97/1 6442 PCT/US96/1 8539 12

The pharmaceutically acceptable salts of the compounds of formula I include the conventional non-toxic salts or the quaternary ammonium salts of the compounds of formula I formed e.g. from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, sulfanilic, 2 -acetoxybenzoic fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic and the like.

The pharmaceutically acceptable salts of the present invention can be synthesized from the compounds of formula I which contain a basic or acidic moiety by conventional chemical methods.

Generally, the salts are prepared by reacting the free base or acid with stoichiometric amounts or with an excess of the desired saltforming inorganic or organic acid or base in a suitable solvent or various combinations of solvents.

The compounds of the present invention may have asymmetric centers and occur as racemates, racemic mixtures, and as individual diastereomers, with all possible isomers, including optical isomers, being included in the present invention.

The compounds of the present invention also may have different tautomeric forms. For example, when Har-(Ra) 0 _3 represents a 4 -hydroxy-3-pyridyl group, the following tautomers are equivalent and within the present invention: WO 97/16442 PCT/US96/18539 37 N

OH O Numerous other tautomeric structures are contemplated as falling within the invention.

This invention relates to method of antagonizing or inhibiting the production or activity of glucagon, thereby reducing the rate of gluconeogenesis and the concentration of glucose in plasma.

The compounds of formula I can be used in the manufacture of a medicament for the prophylactic or therapeutic treatment of disease states in mammals caused by elevated levels of glucose.

This invention also relates to a method of inhibiting or antagonizing the production or activity of cytokines in a mammal in need thereof which comprises administering to said mammal an effective amount of a compound of formula I to antagonize or inhibit cytokine production or activity, such that it is regulated down to normal levels, or in some cases to subnormal levels, so as to ameliorate or prevent the disease state.

The compounds of formula I can be used in the manufacture of a medicament for the prophylactic or therapeutic treatment of disease states in mammals, which are exacerbated or caused by excessive or unregulated cytokine production, more specifically

IL-

1, IL-6, IL-8 or TNF production, by such mammal's cells, such as but not limited to monocytes and/or macrophages.

Compounds of formula I inhibit cytokines, such as IL-1, IL-6, IL-8 and TNF and are therefore useful for treating inflammatory diseases such as rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions.

WO 97/16442 PCT/US96/18539 38 The compounds of formula I may be used to treat other disease states mediated by excessive or unregulated cytokine production or activity. Such diseases include, but are not limited to sepsis, septic shock, endotoxic shock, gram negative sepsis, toxic shock syndrome, adult respiratory distress syndrome, cerebral malaria, chronic pulmonary inflammatory disease, silicosis, pulmonary sarcoisosis, bone resorption diseases, such as osteoporosis, reperfusion injury, graft vs.

host reaction, allograft rejections, fever and myalgias due to infection, such as influenza, cachexia secondary to infection or malignancy, cachexia, secondary to acquired immune deficiency syndrome

(AIDS),

AIDS, ARC (AIDs related complex), keloid formation, scar tissue formation, Crohn's disease, ulcerative colitis, pyresis, AIDS and other viral infections, such as cytomegaliovirus (CMV), influenza virus, and the herpes family of viruses such as Herpes Zoster or Simplex I and II.

The compounds of formula I may also be used topically in the treatment of inflammation such as for the treatment of rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions; inflamed joints, eczema, psoriasis and other inflammatory skin conditions such as sunburn; inflammatory eye conditions including conjunctivitis; pyresis, pain and other conditions associated with inflammation.

Interleukin-1 (IL-1) has been demonstrated to mediate a variety of biological activities thought to be important in immunoregulation and other physiological conditions. [See, Dinarello et al., Rev. Infect. Disease, 6, 51 (1984)]. The myriad of known biological activities of IL-1 include the activation of T helper cells, induction of fever, stimulation of prostaglandin or collagenase production, neutrophil chemotaxis, induction of acute phase proteins and the suppression of plasma iron levels.

There are many disease states in which excessive or unregulated IL-1 production is implicated in exacerbating and/or causing the disease. These include rheumatoid arthritis, osteoarthritis, endotoxemia and/or toxic shock syndrome, other acute or chronic inflammatory disease states such as the inflammatory reaction induced WO 97/16442 PCT/US96/18539 39 by endotoxin or inflammatory bowel disease; tuberculosis, atherosclerosis, muscle degeneration, cachexia, psoriatic arthritis, Reiter's syndrome, rheumatoid arthritis, gout traumatic arthritis, rubella arthritis, and acute synovitis. Recent evidence also links IL-i activity to diabetes and pancreatic 3 cells.

The compounds of formula I are also useful in treating diseases characterized by excessive IL-8 activity. There are many disease states in which excessive or unregulated IL-8 production is implicated in exacerbating and/or causing the disease. These diseases include psoriasis, inflammatory bowel disease, asthma, cardiac and renal reperfusion injury, adult respiratory distress syndrome, thrombosis and glomerulonephritis. The invention includes a method of treating psoriasis, inflammatory bowel disease, asthma, cardiac and renal reperfusion injury, adult respiratory distress syndrome, thrombosis and glomerulonephritis, in a mammal in need of such treatment which comprises administering to said mammal a compound of formula I in an amount which is effective for treating said disease or condition.

The compounds of formula I are normally formulated in accordance with standard pharmaceutical practice as a pharmaceutical composition. This invention, therefore, also relates to a pharmaceutical composition comprising a compound of formula I and a pharmaceutically acceptable carrier or diluent. The compounds of formula I are administered in conventional dosage forms prepared by combining a compound of formula I with standard pharmaceutical carriers according to conventional procedures. The compounds of formula I may also be administered in conventional dosages in combination with a known, second therapeutically active compound. These procedures may involve mixing, granulating and compressing or dissolving the ingredients as appropriate to the desired preparation.

The pharmaceutical carrier employed may be, for example, solid or liquid. Solid carriers include lactose, terra alba, sucrose, talc, gelatin, agar, pectin, acacia, magnesium stearate, stearic acid and the like. Liquid carriers include syrup, peanut oil, olive oil, water and the WO 97/16442 PCT/US96/18539 40 like. Similarly, the carrier may include time delay material, such as glyceryl monostearate or glyceryl distearate, alone or with a wax.

A wide variety of pharmaceutical forms can be employed.

Thus, if a solid carrier is used, the preparation can be in the form of a tablet, hard gelatin capsule, troche or lozenge. The amount of solid will vary widely but preferably will be from about 0.025 mg to about 1 g.

When a liquid carrier is used, the preparation is typically in the form of a syrup, emulsion, soft gelatin capsule, sterile injectable liquid or nonaqueous liquid suspension.

The compounds of formula I may also be administered topically in the form of a liquid, solid or semi-solid. Liquids include solutions, suspensions and emulsions. Solids include powders, poultices and the like. Semi-solids include creams, ointments, gels and the like.

The amount of a compound of formula I, for the methods of use disclosed herein, vary with the compound chosen, the nature and severity of the condition, and other factors left to the discretion of the physician. A representative, topical, anti inflammatory dose of a compound of formula I is from about 0.01 mg to about 1500 mg, administered one to four, preferably one to two times daily.

While it is possible for an active ingredient to be administered alone as the raw chemical, it is preferable to present it as a pharmaceutical formulation. The active ingredient typically comprises about 0.001% to about 90% w/w.

Drops according to the present invention may comprise sterile aqueous or oil solutions or suspensions, and may be prepared by dissolving the active ingredient in a suitable aqueous solution, optionally including a bactericidal and/or fungicidal agent and/or any other suitable preservative, and optionally including a surface active agent. The resulting solution may then be clarified by filtration, transferred to a suitable container which is then sealed and sterilized by autoclaving or maintaining at 98-100C for half an hour. Alternatively, the solution may be sterilized by filtration and transferred to the container by aseptic technique. Examples of bactericidal and fungicidal agents suitable for inclusion in the drops are phenylmercuric nitrate or acetate (0.002%), WO 97/16442 PCT/US96/18539 41 benzalkonium chloride and chlorhexidine acetate Suitable solvents for the preparation of an oily solution include glycerol, diluted alcohol and propylene glycol.

Lotions according to the present invention include those suitable for application to the skin or eye. An eye lotion may comprise a sterile aqueous solution optionally containing a bactericide and may be prepared by methods similar to those for the preparation of drops.

Lotions or liniments for application to the skin may also include an agent to hasten drying and to cool the skin, such as an alcohol or acetone, and/or a moisturizer such as glycerol or an oil such as castor oil or arachis oil.

Creams, ointments or pastes according to the present invention are semi-solid formulations of the active ingredient for external application. They may be made by mixing the active ingredient in finely-divided or powdered form, alone or in solution or suspension in an aqueous or non-aqueous liquid, with the aid of suitable machinery, with a greasy or non-greasy base. The base may comprise hydrocarbons such as hard, soft or liquid paraffin, glycerol, beeswax, a metallic soap; a mucilage; an oil of natural origin such as almond, corn, arachis, castor or olive oil; wool fat or its derivatives, or a fatty acid such as steric or oleic acid together with an alcohol such as propylene glycol or macrogels. The formulation may incorporate any suitable surface active agent such as an anionic, cationic or non-ionic surfactant such as sorbitan esters or polyoxyethylene derivatives thereof.

Suspending agents such as natural gums, cellulose derivatives or inorganic materials such as silicas, and other ingredients such as lanolin may also be included.

The methods of the instant invention may be carried out by delivering the monokine activity interfering agent parenterally. The term 'parenteral' as used herein includes intravenous, intramuscular, intradermal and subcutaneous administration. The intravenous and intramuscular forms of administration are preferred. Appropriate dosage forms for such administration may be prepared by conventional techniques. The instant invention can also be carried out by delivering .WO 97/16442 PCT/US96/185 3 9 42 the compound of formula I intranasally, rectally, transdermally or vaginally.

The compounds of formula I may also be administered by inhalation. By 'inhalation' is meant intranasal and oral inhalation administration. Appropriate dosage forms for such administration, such as an aerosol formulation or a metered dose inhaler, may be prepared by conventional techniques.

Specific examples of formula I may require the use of protecting groups to enable their successful elaboration into the desired structure.

Compounds of formula I may be prepared by the reaction of a benzoin 1, or protected version thereof with a methyl ketone 2 (commercially available or prepared by well established methods) in the presence of potassium cyanide followed by treatment with an alkyl or aryl amine or ammonia or equivalent thereof (ammonium acetate) at elevated temperature (Ceraulo, L. et al, J.

Coupling chemistry may be utilized to introduce R3 groups as shown below in Scheme IX. 4 -unsubstituted pyrroles optionally protected at nitrogen 22 may be halogenated by treatment with electrophilic sources of bromine and iodine to provide 41. The halogen WO 97/16442 PCT/US96/18539 55 may then be coupled with carbon monoxide in the presence of an alcohol to give, after removal of the protecting group, 4-alkoxycarbonyl substituted pyrroles of formula I.

R

3 or R4 groups attached.

The synthesis of pyrroles containing nucleopilic groups for coupling reactions depends on the pyrrole substitution pattern. Lithium anions are prepared by metalation of a regioselectively halogenated pyrrole, or the regioselective deprotonation of the pyrrole preferably by the use of a directing functional group. The resulting anion may then be trapped by a trialkyl stannyl halide or a trialkyl borate or transmetalated to magnesium or zinc by treatment with appropriate halide salts. A further method used to incorporate a trialkyl stannyl group is the coupling of a bromo, iodo or triflate substituted pyrrole with hexaalkylditin in the presence of a palladium catalyst.

The synthesis of pyrroles incorporating electrophilic groups may be carried out by the regioselective halogenation of a WO 97/16442 PCT/US96/18539 58 pyrrole (Pyrroles Part 1, R. Alan Jones,ed., Heterocyclic Compounds ,Vol 48 Part 1, John Wiley, New York, 349-391,1990). The regioselectivity of halogenation will depend on the size, nature and substitution position on the pyrrole ring as well as the presence or absence of the N-alkyl protecting group. Triflates may be prepared by acylation of hydroxy pyrroles with triflic anhydride.

The reaction conditions used will depend on the nature of the coupling species. In the case of magnesium, zinc and stannyl coupling reactions the solvent used is normally toluene or DMF under anhydrous conditions. In the case of boronic acid couplings, a heterogenous system is used of water, toluene, dimethoxyethane or ethanol in the presence of a base such as sodium carbonate or bicarbonate. In general the reaction takes place at an elavated temperature (80-100 oC).

Catalysts used depend on the structure of the components to be coupled as well as the functional groups. Most commonly, tetrakistriphenylphosphinepalladium or palladium bis triphenyl phosphine dichloride are utilized.

Coupling of alkenes or alkynes with 4-halo pyrroles (Heck reaction, see Kalinin, V. Synthesis 413 1991 for a review) will give rise to R 2 (generic nomenclature) alkenyl and alkynyl substituted pyrroles that may be reduced or otherwise modified to provide compounds of formula

I.

Substituents of the pendant groups of the pyrrole ring system are prepared utilizing methods well known to those skilled in the art. For example, functional groups such as halogens, sulfides, nitro groups, ethers and other groups stable to the reaction conditions used in the linear synthesis of the pyrroles are incorporated in the initial steps of the reaction sequence. Sulfides may be oxidized to sulfoxides and sulfones with reagents such as m-chloroperbenzoic acid. Sulfides may also be converted to sulfonyl chlorides by oxidation and chlorination by chlorine in water. Primary amines are prepared from nitro groups by catalytic (Pd/C, H2 or Raney Nickle, H2) or chemical means (CoCl2, NaBH4). Alkylation of amines to give secondary and tertiary amines SWO 97/16442 PCT/US96/185 3 9 59 is achieved by reductive alkylation (aldehyde, NaCNBH4) or alkylation with an alkyl group substituted with a leaving group in the presence of a base such as K2C03. Tertiary amines may, alternatively, be carried through the reaction sequence to the pyrroles. Acylation of primary or secondary amines with activated acids, achloroformates, isocyanates and chlorosulfonates will give rise to amides, carbamates, ureas and sulonamides respectively.

Other methods of preparing amides and ureas are useful; treatment of the amine with phosgene, or an equivalent thereof, followed by acyaltion of an alcohol or amine with the intermediate activated chloroformamide. Carboxylic acids are best introduced as esters early in the synthesis. Saponification will provide carboxylic acids. Transesterification or esterification of the acids will give esters.

Carboxylic acids may be converted to amides by activation and reaction with amines. Phenols are best introduced in a protected form early in the synthetic sequence to the pyrrole. Removal of the protecting group provides a phenol which may subsequently be alkylated in the presence of an alkylating agent and base to give an ether or acylated with an isocyanate to give carbamates. Phenols may be converted to aryl ethers by reaction with an aryl bismuthane in the presence of copper II acetate.

Aryl and heteroaryl groups may be attached to pyrrole pendant aryl and heteroaryl groups by application of coupling chemistry technology as outlined above.

The sequence and conditions of the reaction steps is dependant on the structure and functional groups present. Protecting groups may be necessary and may be chosen with reference to "Protecting Groups in Oranic Synthesis, Greene T. Wiley-Inerscience, New York, 1981". The blocking groups are readily removable, i.e., they can be removed, if desired, by procedures which will not cause cleavage or other disruption of the remaining portions of the molecule.

Such procedures include chemical and enzymatic hydrolysis, treatment with chemical reducing or oxidizing agents under mild conditions, treatment with fluoride ion, treatment with a transition metal catalyst and a nucleophile, and catalytic hydrogenation.

Determination of IL-l1 TNF- IL-6 and prostanoid producton LPS or IL-1 stimulated PBMC's

ELISA

Human IL-1 can be detected in cell-culture supematants or whole blood with the following specific trapping ELISA. Ninety-six well plastic plates (Immulon 4; Dynatech) are coated for 12 hours at 4°C with I mg/mL protein-A affinity chromatography purified mouse anti-human IL-lb monoclonal antibody (purchased as an ascites preparation from LAO Enterprise, Gaithersburg Maryland.) diluted in Dulbecco's phosphate-buffered saline (-MgCI 2 -CaCI 2 The plates are washed with PBS-Tween (Kirkegaard and Perry) then blocked with 1% BSA diluent and blocking solution (Kirkegaard and Perry) for minutes at room temperature followed by washing with PBS Tween.

IL-1 standards are prepared from purified recombinant IL-lp produced from E. coli.. The highest concentration begins at 10 ng/mL followed by 11 two-fold serial dilution's. For detection of IL-1p from cell culture supernatants or blood plasma, 10 25 mL of supematant is added to each test well with 75 90 mL of PBS Tween. Samples are incubated at room temperature for 2 hours then washed 6 times with PBS Tween on an automated plate washer (Dennly). Rabbit anti-human IL-1p polyclonal antisera diluted 1:500 in PBS-Tween is added to the plate and incubated for 1 hour at room temperature followed by six washes with PBS-Tween. Detection of bound rabbit anti-IL-1 IgG is accomplished with Fab' fragments of Goat anti-rabbit IgG-horseradish peroxidase conjugate (Accurate Scientific) diluted 1:10,000 in PBS- Tween. Peroxidase activity was determined using TMB peroxidase substrate kit (Kirkegaard and Perry) with quantitation of color intensity on a 9 6-well plate Molecular Devices spectrophotometer set to deter- WO 97/16442 PCT/US96/18539 105 mine absorbance at 450 nM. Samples are evaluated using a standard curve of absorbance versus concentration. Four-parameter logistics analysis generally is used to fit data and obtain concentrations of unknown compounds.

TNF-ca

ELISA

Immulon 4 (Dynatech) 9 6-well plastic plates are coated with a 0.5 mg/mL solution of mouse anti-human TNF-a monoclonal antibody. The secondary antibody is a 1:2500 dilution of a rabbit anti-human TNF-a polyclonal serum purchased from Genzyme. All other operations are identical to those described above for IL-lb. The standards are prepared in PBS-Tween 10% FBS or HS. Eleven 2 fold dilution's are made beginning at 20 ng/mL TNF-a.

IL-6 ELISA Levels of secreted human IL-6 are also determined by specific trapping ELISA as described previously in Chin and Kostura, J. Immunol. 151, 5574-5585 (1993). (Dynatech) ELISA plates are coated with mouse anti-human IL-6 monoclonal antibody diluted to mg/ml in PBS. The secondary antibody, a rabbit anti-human 1L-6 polyclonal antiserum, is diluted 1:5000 with PBS-Tween. All other operations are identical to those described above for IL-I3. The standards are prepared in PBS-Tween 10% FBS or HS. Eleven 2 fold dilution's are made beginning at 50 ng/mL IL-6.

PGE2 production Prostaglandin E2 is detected in cell culture supernatants from LPS or IL-I stimulated PBMC's using a commercially available enzyme immunoassay The assay purchased from the Cayman Chemical (Catalogue number 514010) and is run exactly according to the manufacturers instructions.

tereukin8 (L-8 WO 97/16442 PC'( I/S96/18539 106 The present compounds can also be assayed for IL-8 inhibitory activity as discussed below. Primary human umbilical cord endothelial cells (HUVEC) (Cell Systems, Kirland, Wa) are maintained in culture medium supplemented with 15% fetal bovine serum and I% CS-HBGF consisting of ocFGF and heparin. The cells are then diluted before being plated (250 il) into gelatin coated 9 6-well plates.

Prior to use, culture medium is replaced with fresh medium (2001p).

Buffer or test compound (251p, at appropriate concentrations) is then added to'each well in quadruplicate wells and the plates incubated for 6h in a humidified incubator at 37°C in an atmosphere of 5% CO 2 At the end of the incubation period, supernatant is removed and assayed for IL-8 concentration using an IL-X ELISA kit obtained from R&D Systems (Minneapolis, MN). All data is presented as mean value (ng/ml) of multiple samples based on the standard curve. IC50 values where appropriate are generated by non-linear regression analysis.
