Description: SUBSTITUTED PYRAZOLES AS p38 KINASE INHIBITORS Cross-Reference to Related Application This application claims priority from U.S. Provisional Application Serial No. 60/047,570 filed May 22, 1997. Field of the Invention This invention relates to a novel group of pyrazole compounds, compositions and methods for treating p38 kinase mediated disorders. Background of the Invention Mitogen-activated protein kinases (MAP) is a family of proline-directed serine/threonine kinases that activate their substrates by dual phosphorylation. The kinases are activated by a variety of signals including nutritional and osmotic stress, UV light, growth factors, endotoxin and inflammatory cytokines. The p38 MAP kinase group is a MAP family of various isoforms, including p38α, p38(S and p38γ, and is responsible for phosphorylating and activating transcription factors (e.g. ATF2 , CHOP and MEF2C) as well as other kinases (e.g. MAPKAP-2 and MAPKAP-3) . The p38 isoforms are activated by bacterial lipopolysaccharide, physical and chemical stress and by pro-inflammatory cytokines, including tumor necrosis factor (TNF-α) and interleukin-1 (IL-1) . The products of the p38 phosphorylation mediate the production of inflammatory cytokines, including TNF and IL-1, and cyclooxygenase-2. TNF-α is a cytokine produced primarily by activated monocytes and macrophages . Excessive or unregulated TNF production has been implicated in mediating a number of diseases. Recent studies indicate that TNF has a causative role in the pathogenesis of rheumatoid SUBSmUTE8HEET(RULE26) arthritis. Additional studies demonstrate that inhibition of TNF has broad application in the treatment of inflammation, inflammatory bowel disease, multiple sclerosis and asthma. TNF has also been implicated in viral infections, such as HIV, influenza virus, and herpes virus including herpes simplex virus type-1 (HSV-1) , herpes simplex virus type-2 (HSV-2) , cytomegalovirus (CMV) , varicella-zoster virus (VZV) , Epstein-Barr virus, human herpesvirus-6 (HHV-β) , human herpesvirus-7 (HHV-7) , human herpesvirus-8 (HHV-8) , pseudorabies and rhinotracheitis, among others. IL-8 is another pro-inflammatory cytokine, which is produced by mononuclear cells, fibroblasts, endothelial cells, and keratinocytes, and is associated with conditions including inflammation. IL-1 is produced by activated monocytes and macrophages and is involved in the inflammatory response. IL-1 plays a role in many pathophysiological responses including rheumatoid arthritis, fever and reduction of bone resorption. TNF, IL-1 and IL-8 affect a wide variety of cells and tissues and are important inflammatory mediators of a wide variety of disease states and conditions. The inhibition of these cytokines by inhibition of the p38 kinase is of benefit in controlling, reducing and alleviating many of these disease states.

This hydrophobic cavity is believed to form as the 3- position substituent binds to a specific peptide sequence of the enzyme. In particular, it is believed to bind to the sidechains of Lys 52 , Glu 69 , Leu 73 , Ile 82 , Leu 84 , Leu 101 and the methyl group of the Thr 103 sidechain of p38 kinase at the ATP binding site (wherein the numbering scheme corresponds to the numbering scheme conventionally used for ERK-2) . Where the 3 -position substituent is aryl or heteroaryl, such aryl or heteroaryl may be further substituted. It is hypothesized that such ring substituents may be beneficial in preventing hydroxylation or further metabolism of the ring. The substituent at the 4 -position of the pyrazole ring is one that is a partial mimic of the adenine ring of ATP, although it may be further elaborated. Preferably, it is a planar substituent terminated by a suitable hydrogen bond acceptor functionality. It is hypothesized that this acceptor hydrogen bonds to the backbone N-H of the Met 106 residue while one edge of this substituent is in contact with bulk solvent. Substitution at the 5-position of the pyrazole ring is well tolerated and can provide increased potency and selectivity. It is hypothesized that such substituents extend out in the direction of the bulk solvent and that suitable polar functionality placed at its terminus can interact with the sidechain of Asp 109 , leading to increased potency and selectivity. Similarly, substitution on the nitrogen atom at the 1- or 2 -position of the pyrazole ring is well tolerated and can provide increased potency. It is hypothesized that a hydrogen substituent attached to one of the ring nitrogen atoms is hydrogen bonded to Asp 165 . Preferably, the nitrogen atom at the 2 -position is double bonded to the carbon atom at the 3 -position of the pyrazole while 8yøgπTϋTE8t Er(RϋLE26} the nitrogen atom at the 1 -position of the pyrazole is available for substitution with hydrogen or other substituents . The 5-position substitutent and the 1- or 2-position substituent of the pyrazole can be selected so as to improve the physical characteristics, especially aqueous solubility and drug delivery performance, of the substituted pyrazole. Preferably, however, these substituents each have a molecular weight less than about 360 atomic mass units. More preferably, these substituents each have a molecular weight less than about less than about 250 atomic mass units. Still more preferably, these substituents have a combined molecular weight less than about 360 atomic mass units. A class of substituted pyrazoles of particular interest consists of those compounds having the formula: wherein R 1 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical having a molecular weight less than about 360 atomic mass units; and R 2 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical that binds with p38 kinase at said ATP binding site of p38 kinase; and R 3 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical having a hydrogen bond acceptor functionality; and SUeSTTRJTESHEET(RULE26) R 4 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical having a molecular weight less than about 360 atomic mass units; provided R 3 is not 2 -pyridinyl when R 4 is a phenyl ring containing a 2 -hydroxy substituent and when R 1 is hydrido; further provided R 2 is selected from aryl, heterocyclyl, unsubstituted cycloalkyl and cycloalkenyl when R 4 is hydrido; and further provided R 4 is not methylsulfonylphenyl ; or a pharmaceutically-acceptable salt or tautomer thereof . A class of substituted pyrazoles of particular interest consists of those compounds of Formula XI wherein R 1 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical having a molecular weight less than about 360 atomic mass units; and R 2 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical wherein said radical binds with Lys 52 , Glu 69 , Leu 73 , Ile 82 , Leu 84 , Leu 101 , and Thr 103 sidechains at said ATP binding site of p38 kinase, said radical being substantially disposed within a hydrophobic cavity formed during said binding by p38 kinase at the ATP binding site; and R 3 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical having a hydrogen bond acceptor functionality that hydrogen bonds with the N-H backbone of Met 106 of p38 kinase; and R 4 is a hydrocarbyl, heterosubstituted hydrocarbyl or heterocyclyl radical having a molecular weight less than about 360 atomic mass units.

Also included in the family of compounds of Formula I are the pharmaceutically-acceptable salts thereof. The term "pharmaceutically-acceptable salts" embraces salts commonly used to form alkali metal salts and to form addition salts of free acids or free bases. The nature of the salt is not critical, provided that it is pharmaceutically-acceptable. Suitable pharmaceutically- acceptable acid addition salts of compounds of Formula I may be prepared from an inorganic acid or from an organic acid. Examples of such inorganic acids are hydrochloric, hydrobromic, hydroiodic, nitric, carbonic, sulfuric and phosphoric acid. Appropriate organic acids may be selected from aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclyl, carboxylic and sulfonic classes of organic acids, example of which are formic, acetic, propionic, succinic, glycolic, gluconic, lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric, pyruvic, aspartic, glutamic, benzoic, anthranilic, mesylic, stearic, salicylic, p- hydroxybenzoic, phenylacetic, mandelic, embonic (pamoic) , methanesulfonic, ethanesulfonic, benzenesulfonic, pantothenic, toluenesulfonic, 2-hydroxyethanesulfonic, sulfanilic, cyclohexylaminosulfonic, algenic, β- hydroxybutyric, galactaric and galacturonic acid. Suitable pharmaceutically-acceptable base addition salts of compounds of Formula I include metallic salts and organic salts. More preferred metallic salts include, but are not limited to appropriate alkali metal (group la) salts, alkaline earth metal (group Ila) salts and other physiological acceptable metals. Such salts can be made from aluminum, calcium, lithium, magnesium, potassium, sodium and zinc. Preferred organic salts can be made from tertiary amines and quaternary ammonium salts, including in part, tromethamine, diethylamine, N,N' -dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N- 8UBSnTUTESHEET(WJLE26) methylglucamine) and procaine . All of these salts may be prepared by conventional means from the corresponding compound of Formulas I-III by reacting, for example, the appropriate acid or base with the compound of Formulas I- III. General Synthetic Procedures The compounds of the invention can be prepared according to the following procedures of Schemes I -XVIII wherein R 1 , R 2 , R 3 , R 4 , R 5 and Ar 1 are as previously defined for the compounds of Formula I, IX, X and XI except where expressly noted. SCHEME I Scheme I shows the synthesis of pyrazole 5 by two routes. Condensation of the pyridylmethyl ketone 1 with aldehyde 2 in the presence of a base, such as piperidine, in a solvent, such as toluene or benzene, either in the absence or the presence of acetic acid at reflux, provides the α, /3-unsaturated ketone 3. In route 1, ketone 3 is first converted to epoxide 4, such as by treatment with hydrogen peroxide solution at room temperature, in the presence of base such as sodium hydroxide. Treatment of epoxide 4 with hydrazine in ethanol or other suitable solvent at a temperature ranging up to reflux, yields pyrazole 5. In route 2, ketone 3 is condensed directly with tosyl hydrazide in the presence of an acid such as acetic acid, at reflux, to provide pyrazole 5. Alternatively, the intermediate tosyl hydrazone 6 may be isolated, conversion of it to pyrazole 5 is effected by treatment with a base, such as potassium hydroxide, in a suitable solvent, such as ethylene glycol, at a temperature ranging from 25 °C up to 150 °C. SUBSTmnESHEET(RULE26) SCHEME II N H N H 2 1 2 Scheme II shows the synthesis of pyrazole 12 of the present invention. The treatment of pyridine derivative 7 with ester 8 in the presence of a base, such as sodium bis (trimethylsilyl) amide, in a suitable solvent, such as tetrahydrofuran, gives ketone 9. Treatment of ketone 9 or a hydrohalide salt of ketone 9 with a halogenating agent, such as bromine, N-bromosuccinimide or N- chlorosuccinimide, in suitable solvents, such as acetic acid, methylene chloride, methanol, or combinations thereof, forms the α-halogenated ketone 10 (wherein X is halo) . Examples of suitable hydrohalide salts include the hydrochloride and hydrobromide salts. Reaction of haloketone 10 with thiosemicarbazide 11 (where R 6 and R 7 can be hyrido, lower alkyl, phenyl, heterocyclyl and the like or where R 6 and R 7 form a heterocyclyl ring optionally containing an additional heteroatom) provides pyrazole 12. Examples of suitable solvents for this reaction are ethanol and dimethylformamide . The reaction may be carried out in the presence or absence of base or acid at temperatures ranging from room temperature to 100 °C. Thiosemicarbazides which are not commercially available may be conveniently prepared by one skilled in the art by first reacting an appropriate amine with carbon disulfide in the presence of a base, followed by treatment with an alkylating agent such as methyl iodide. Treatment of the resultant alkyl dithiocarbamate with hydrazine results in the desired thiosemicarbazide . This chemistry is further described in E. Lieber and R.C. Orlowski, J. Org . Chem. , Vol. 22, p. 88 (1957). An alternative approach is to add hydrazine to appropriately substituted thiocyanates as described by Y. Nomoto et al., Chem. Pharm. Bull. , Vol. 39, p.86 (1991). The Lieber and Nomoto publications are incorporated herein by reference . SCHEME III 1 9 βϋBSπTUTESt€ETCRϋLE∑e) Scheme III shows the synthesis of pyrazole 19 in more general form by three routes. In Route 1, ketone 13 is condensed with hydrazine 14 to give the substituted hydrazide 16, which is then reacted with acyl halide or anhydride 17 at low temperature to provide acyl hydrazone 18. Upon heating at a temperature up to 200°C, acyl hydrazone 18 is converted to pyrazole 19. In Route 2, acyl hydrazone 18 is formed directly by reaction of ketone 13 with acyl hydrazide 15, formed by reaction of hydrazine with a carboxylic acid ester, at room temperature. Heating acyl hydrazone 18 as above then provides pyrazole 19. In Route 3, ketone 13 is treated with acyl hydrazide 15 at a suitable temperature, ranging from room temperature to about 200 °C, to give pyrazole 19 directly. Alternatively, this condensation may be carried out in an acidic solvent, such as acetic acid, or in a solvent containing acetic acid. SCHEME IV 8UeSfmUTE8HEET(RULE26) Synthetic Scheme IV describes the preparation of pyrazole 19. SCHEME V 31 32 33 X = ha I y a l y l n1 _ Me, CH 2 CH 2 OH eye I opropy I , 4- py r ϊ dy I , 4- i mi dazo l y l Scheme V shows the two step synthesis of the 3- substituted 4-pyridyl-5-arylpyrazoles 33 of the present invention by cyclization of hydrazone dianions with carboxylates . In step 1, the reaction of substituted pyridylmethyl ketones 31 (prepared, for example, as later described in Scheme IX) with hydrazines in the presence of solvents such as ethanol gives ketohydrazones 32. Examples of suitable hydrazines include, but are not limited to, phenylhydrazine and p-methoxyphenylhydrazine. In step 2, the hydrazones 32 are treated with two equivalents of a base such as sodium bis (trimethylsilyl) amide in a suitable solvent such as tetrahydrofuran to generate dianions. This reaction may be carried out at temperatures of about 0 °C or lower. SUBSmTUTESHEEr(RUL£26) In the same step, the dianions then are condensed with esters such as methyl isonicotinate, methyl cyclopropanecarboxylate, to give the desired pyrazoles 33. It may be necessary to treat the product from this step with a dehydrating agent, such as a mineral acid, to produce the target pyrazole in some instances. 8UBSmU1ESHE£r(RULE2e) SCHEME VI R d R 4 X 35 36 Scheme VI shows an alternative method for synthesizing pyrazoles which are unsubstituted at the 5 position of the ring. In accordance with this method, a heteroarylmethyl ketone 34 is synthesized by first treating a heteroarylmethane with a strong base such as lithium hexamethyldisilazide or lithium diisopropylamide . Examples of suitable heteroarylmethanes are 4- methylpyridine, 4-methylpyrimidine, 2 , 4-dimethylpyridine, 2-chloro-4-methylpyrimidine, 2-chloro-4-methylpyridine and 2-fluoro-4-methylpyridine . The resulting heteroarylmethyl lithium species is then reacted with a substituted benzoate ester to produce ketone 34. Examples of suitable benzoate esters are methyl and ethyl p-fluorobenzoate and ethyl and methyl p-chlorobenzoate . Ketone 34 is converted to the aminomethylene derivative 35 by reaction with an aminomethylenating agent such as dimethylformamide dimethyl acetal or tert- butoxybis (dimethylamino) methane . Ketone 35 is converted to pyrazole 36 by treatment with hydrazine. A modification of this synthetic route serves to regioselectively synthesize pyrazole 38 which contains a substituted nitrogen at position 1 of the ring. Ketone 34 is first converted to hydrazone 37 by reaction with the appropriate substituted hydrazine. Examples of suitable hydrazines are N-methylhydrazine and N- (2- hydroxyethyl) hydrazine . Reaction of hydrazone 37 with an aminomethylenating agent produces pyrazole 38. Examples of suitable aminomethylenating agents include dimethylformamide dimethyl acetal and tert- butoxybis (dimethylamino) methane . In cases where the R 3 substituent of pyrazoles 36 and 38 bears a leaving group such as a displaceable halogen, subsequent treatment with an amine produces an amino- substituted heteroaromatic derivative. Examples of such amines include benzylamine, cyclopropylamine and ammonia. The leaving group may also be replaced with other nucleophiles such as mercaptides and alkoxides. Examples of substitutable R 3 groups include, but are not limited to, 2-chloropyridinyl and 2 -bromopyridinyl groups. SCHEME VII σ. EDC/^OEjT NHR 10 R 11 42 41 Scheme VII describes the preparation of derivatives from pyrazole 5 (prepared in accordance with Scheme I) when R 2 = CH 3 . Oxidation of pyrazole 5 gives carboxylic acid 39, which is then reduced to hydroxymethyl compound 40, or coupled with amine NR 10 R 11 (wherein R 10 and R 11 are independently selected, for example, from hydrogen, alkyl and aryl, or together with the nitrogen atom to which they are attached form a 4-8 membered ring that may contain one or more additional heteroatoms selected from oxygen, nitrogen or sulfur) to form amide 41 followed by reduction to generate amine derivative 42. SCHEME VIII Base R 1 -X 44 45 Scheme VIII illustrates the synthesis of pyrazoles 44 and 45 from pyrazole 43. The alkylation of the ring nitrogen atoms of pyrazole 43 can be accomplished using conventional techniques. Treatment of pyrazole 43 with an appropriate base (for example, sodium hydride) followed by treatment with an alkyl halide (for example, CH 3 I) yields a mixture of isomers 44 and 45. 8UBSmUmSHEEr(RULE26) SCHEME IX y ldisi lazide n, RT "desoxybenzo i n ' d i me t hy I f or mam i e dimethyl aceta C4 fold excess) tetrahydrofuran 1 volume) RT 49 5D SUB§mU!£8HEET(BULE26) Scheme IX illustrates the synthesis of 3-aryl-4- pyridyl-pyrazoles of the present invention. Benzoate 46 is reacted with pyridine 47 in the presence of a strong base, such as an alkali metal hexamethyldisilazide (preferably sodium hexamethyldisilazide or lithium hexamethyldisilazide), in a suitable solvent, such as tetrahydrofuran, to give desoxybenzoin 48. Desoxybenzoin 48 is then converted to ketone 49 by treatment with an excess of dimethylformamide dimethyl acetal . Ketone 49 is then reacted with hydrazine hydrate in a suitable solvent such as ethanol to yield pyrazole 50. In Scheme IX, R 12 represents one or more radicals independently selected from the optional substituents previously defined for R 4 . Preferably, R 12 is hydrogen, alkyl, halo, trifluoromethyl, methoxy or cyano, or represents methylenedioxy . The 3 -aryl-4-pyrimidinyl-pyrazoles of the present invention can be synthesized in the manner of Scheme IX by replacing pyridine 47 with the corresponding pyrimidine. In a similar manner, Schemes X through XVII can be employed to synthesize 3 -aryl-4 -pyrimidinyl - pyrimidines corresponding to the 3 -aryl-4 -pyrimidinyl - pyrazoles shown in those schemes . SlK nTUTESHEEr(RULE26) SCHEME X 52 Scheme X illustrates one variation of Scheme IX that can be used to synthesize 3 -aryl -4 -pyridyl -pyrazoles that are further substituted on the nitrogen atom at position 1 of the pyrazole ring. If desoxybenzoin 48 (prepared in accordance with Scheme IX) instead is first converted to hydrazone 51 by treatment with hydrazine and hydrazone 51 is then treated with dimethylformamide dimethyl acetal, then the resulting product is pyrazole 52. Schemes XI through XVIII illustrate further modifications that can be made to Scheme IX to synthesize other 3 -aryl -4 -pyridyl-pyrazoles having alternative substituents . 8UB8mUΪESHEET(RULE28) inor product 54 SCHEME XII 5 5 5 6 In Scheme XII, X is chloro, fluoro or bromo; R 13 is, for example, hydrogen, alkyl, phenyl, aralkyl, heteroarylalkyl, amino or alkylamino; and R 20 is, for example, hydrogen or alkyl.

SϋBSITrϋTESHEET(Rl E26) SCHEME XVIII 7 2 7 1 Compounds wherein the 2 -position of the pyridine ring is substituted by a carboxyl group or a carboxyl derivative may be synthesized according to the procedures outline in Scheme XVIII. The starting pyridyl pyrazole 67 is converted to the 2 -cyano derivative 68 by first 8UBSOTTUTCSHEEr(RUi£26) conversion to its pyridine N-oxide by reaction with an oxidizing agent such as m-chloroperoxybenzoic acid. Treatment of the pyridine N-oxide with trimethylsilyl cyanide followed by dimethylcarbamoyl chloride produces the 2-cyano compound 68. Compound 68 is converted to its carboxamide 69 by reaction with hydrogen peroxide in the presence of a suitable base. Examples of suitable bases include potassium carbonate and potassium bicarbonate. Carboxamide 69 is converted to its methyl ester 70 by reaction with dimethylformamide dimethyl acetal in methanol. The ester 70 is converted to its carboxylic acid 71 by saponification. Typical saponification conditions include reaction with a base such as sodium hydroxide or potassium hydroxide in a suitable solvent such as ethanol or ethanol and water or methanol and water or the like. Ester 70 is also convertible to substituted amide 72 by treatment with a desired amine, such as methylamine at a suitable temperature. Temperatures may range from room temperature to 180 °C. In Scheme XVIII, R 18 and R 19 are independently selected, for example, from hydrogen, alkyl and aryl, or together with the nitrogen atom to which they are attached form a 4-8 membered ring that may contain one or more additional heteroatoms selected from oxygen, nitrogen or sulfur. The following examples contain detailed descriptions of the methods of preparation of compounds of Formulas I, XI, X and XI.

These detailed descriptions are presented for illustrative purposes only and are not intended as a restriction on the scope of the invention.

First strand cDNA was synthesized from total RNA as follows: 2 μg of RNA was annealed to 100 ng of random hexamer primers in a 10 μl reaction by heating to 70 °C for 10 minutes followed by 2 minutes on ice. cDNA was then synthesized by adding 1 μl of RNAsin (Promega, Madison WI) , 2 μl of 50 mM dNTP's, 4 μl of 5X buffer, 2 μl of 100 mM DTT and 1 μl (200 U) of Superscript II ™ AMV reverse transcriptase. Random primer, dNTP's and Superscript TM reagents were all purchased from Life-Technologies, Gaithersburg, MA. The reaction was incubated at 42 °C for 1 hour. Amplification of p38 cDNA was performed by aliquoting 5 μl of the reverse transcriptase reaction into a 100 μl PCR reaction containing the following: 80 μl dH2θ, 2 μl 50 mM dNTP's, 1 μl each of forward and reverse primers 8UBSmUϊESHEET(RULE28) (50 pmol/μl) , 10 μl of 10X buffer and 1 μl Expand TM polymerase (Boehringer Mannheim) . The PCR primers incorporated Bam HI sites onto the 5' and 3' end of the amplified fragment, and were purchased from Genosys . The sequences of the forward and reverse primers were 5 ' -GATCGAGGATTCATGTCTCAGGAGAGGCCCA-3 ' and 5 ' GATCGAGGATTCTCAGGACTCCATCTCTTC-3 ' respectively . The PCR amplification was carried out in a DNA Thermal Cycler (Perkin Elmer) by repeating 30 cycles of 94 °C for 1 minute 60 ° c f° r 1 minute and 68 °C for 2 minutes. After amplification, excess primers and unincorporated dNTP's were removed from the amplified fragment with a Wizard ™ PCR prep (Promega) and digested with Bam HI (New England Biolabs) . The Bam HI digested fragment was ligated into BamHI digested pGEX 2T plasmid DNA (PharmaciaBiotech) using T-4 DNA ligase (New England Biolabs) as described by T. Maniatis, Molecular Cloning: A Laboratory Manual , 2nd ed . (1989) . The ligation reaction was transformed into chemically competent E. coli DH10B cells purchased from Life-Technologies following the manufacturer's instructions. Plasmid DNA was isolated from the resulting bacterial colonies using a Promega Wizard™ miniprep kit. Plasmids containing the appropriate Bam HI fragment were sequenced in a DNA Thermal Cycler (Perkin Elmer) with Prism™ (Applied Biosystems Inc.). cDNA clones were identified that coded for both human p38a isoforms (Lee et al . Nature 372, 739) . One of the clones which contained the cDNA for p38a-2 (CSBP-2) inserted in the cloning site of pGEX 2T, 3' of the GST coding region was designated pMON 35802. The sequence obtained for this clone is an exact match of the cDNA clone reported by Lee et al . This expression plasmid allows for the production of a GST-p38a fusion protein. SUBST1TUTESH£ET(RU E26) Expression of human p38a: GST/p38a fusion protein was expressed from the plasmid pMON 35802 in E. coli , stain DH10B (Life Technologies, Gibco-BRL) . Overnight cultures were grown in Luria Broth (LB) containing 100 mg/ml ampicillin. The next day, 500 ml of fresh LB was inoculated with 10 ml of overnight culture, and grown in a 2 liter flask at 37 °C with constant shaking until the culture reached an absorbance of 0.8 at 600 nm. Expression of the fusion protein was induced by addition of isopropyl b-D- thiogalactosidse (IPTG) to a final concentration of 0.05 mM. The cultures were shaken for three hours at room temperature, and the cells were harvested by centrifugation. The cell pellets were stored frozen until protein purification. Purification of p38 Kinase-α: All chemicals were from Sigma Chemical Co. unless noted. Twenty grams of E. coli cell pellet collected from five 1 L shake flask fermentations was resuspended in a volume of PBS (140 mM NaCl, 2.7 mM KC1 , 10 M Na 2 HP0 4 , 1.8 mM KH 2 P0 4/ pH 7.3) up to 200 ml. The cell suspension was adjusted to 5 mM DTT with 2 M DTT and then split equally into five 50 ml Falcon conical tubes. The cells were sonnicated (Ultrasonics model W375) with a 1 cm probe for 3 X 1 minutes (pulsed) on ice. Lysed cell material was removed by centrifugation (12,000 x g, 15 minutes) and the clarified supernatant applied to glutathione-sepharose resin (Pharmacia) . Glutathione-Sepharose Affinity Chromatography: Twelve ml of a 50% glutathione sepharose-PBS suspension was added to 200 ml clarified supernatant and incubated batchwise for 30 minutes at room temperature. The resin was collected by centrifugation (600 x g, 5 min) and washed with 2 x 150 ml PBS/1% Triton X-100, suesmurESHEεr(R JE26} followed by 4 x 40 ml PBS. To cleave the p38 kinase from the GST-p38 fusion protein, the glutathione-sepharose resin was resuspended in 6 ml PBS containing 250 units thrombin protease (Pharmacia, specific activity > 7500 units/mg) and mixed gently for 4 hours at room temperature. The glutathione-sepharose resin was removed by centrifugation (600 x g, 5 min) and washed 2 x 6 ml with PBS. The PBS wash fractions and digest supernatant containing p38 kinase protein were pooled and adjusted to 0.3 mM PMSF. Mono 0 Anion Exchange Chromatography: The thrombin-cleaved p38 kinase was further purified by FPLC-anion exchange chromatography. Thrombin-cleaved sample was diluted 2-fold with Buffer A (25 mM HEPES, pH 7.5, 25 mM beta-glycerophosphate, 2 mM DTT, 5% glycerol) and injected onto a Mono Q HR 10/10 (Pharmacia) anion exchange column equilibrated with Buffer A. The column was eluted with a 160 ml 0.1 M-0.6 M NaCl/Buffer A gradient (2 ml/minute flowrate) . The p38 kinase peak eluting at 200 mM NaCl was collected and concentrated to 3-4 ml with a Filtron 10 concentrator (Filtron Corp.). Sephacryl S100 Gel Filtration Chromatography: The concentrated Mono Q- p38 kinase purified sample was purified by gel filtration chromatography (Pharmacia HiPrep 26/60 Sephacryl S100 column equilibrated with Buffer B (50 mM HEPES, pH 7.5, 50 mM NaCl, 2 mM DTT, 5% glycerol) ) . Protein was eluted from the column with Buffer B at a 0.5 ml/minute flowrate and protein was detected by absorbance at 280 nm. Fractions containing p38 kinase (detected by SDS-polyacrylamide gel electrophoresis) were pooled and frozen at -80 °C. Typical purified protein yields from 5 L E. coli shake flasks fermentations were 35 mg p38 kinase. SUBSTTrUTE8HEET(RUUE26) In Vitro Assay The ability of compounds to inhibit human p38 kinase alpha was evaluated using two in vitro assay methods . In the first method, activated human p38 kinase alpha phosphorylates a biotinylated substrate, PHAS-I (phosphorylated heat and acid stable protein-insulin inducible) , in the presence of gamma 32 P-ATP ( 32 P-ATP) . PHAS-I was biotinylated prior to the assay and provides a means of capturing the substrate which is phosphorylated during the assay. p38 Kinase was activated by MKK6. Compounds were tested in 10 fold serial dilutions over the range of 100 μM to 0.001 μM using 1% DMSO. Each concentration of inhibitor was tested in triplicate. All reactions were carried out in 96 well polypropylene plates. Each reaction well contained 25 mM HEPES pH 7.5, 10 mM magnesium acetate and 50 μM unlabeled ATP. Activation of p38 was required to achieve sufficient signal in the assay. Biotinylated PHAS-I was used at 1-2 μg per 50 μl reaction volume, with a final concentration of 1.5 μM. Activated human p38 kinase alpha was used at 1 μg per 50 μl reaction volume representing a final concentration of 0.3 μM. Gamma 32p_ ATP was used to follow the phosphorylation of PHAS-I. 32 P-ATP has a specific activity of 3000 Ci/mmol and was used at 1.2 μCi per 50 μl reaction volume. The reaction proceeded either for one hour or overnight at 30 °C. Following incubation, 20 μl of reaction mixture was transferred to a high capacity streptavidin coated filter plate (SAM-streptavidin-matrix, Promega) prewetted with phosphate buffered saline. The transferred reaction mix was allowed to contact the streptavidin membrane of the Promega plate for 1-2 minutes. Following capture of biotinylated PHAS-I with 32 P incorporated, each well was washed to remove unincorporated 32 P-ATP three times with 2M NaCl, three washes of 2M NaCl with 1% phosphoric, three washes of distilled water and finally a single wash SUBSmUTESHEEr(RULE26) of 95% ethanol. Filter plates were air dried and 20 μl of scintillant was added. The plates were sealed and counted. Results are shown in Table 4. A second assay format was also employed that is based on p38 kinase alpha induced phosphorylation of EGFRP (epidermal growth factor receptor peptide, a 21 mer) in the presence of 33 P-ATP. Compounds were tested in 10 fold serial dilutions over the range of lOOμM to O.OOlμM in 1% DMSO. Each concentration of inhibitor was tested in triplicate. Compounds were evaluated in 50μl reaction volumes in the presence of 25 mM Hepes pH 7.5, 10 mM magnesium acetate, 4% glycerol, 0.4% bovine serum albumin, 0.4mM DTT, 50μM unlabeled ATP, 25 μg EGFRP (200μM) , and 0.05 uCi gamma 33 P-ATP. Reactions were initiated by addition of 0.09 μg of activated, purified human GST-p38 kinase alpha. Activation was carried out using GST-MKK6 (5 : l,p38 :MKK6) for one hour at 30 °C in the presence of 50μM ATP. Following incubation for 60 minutes at room temperature, the reaction was stopped by addition of 150μl of AG 1X8 resin in 900 mM sodium formate buffer, pH 3.0 (1 volume resin to 2 volumes buffer) . The mixture was mixed three times with pipetting and the resin was allowed to settle. A total of 50μl of clarified solution head volume was transferred from the reaction wells to Microlite-2 plates. 150μl of Microscint 40 was then added to each well of the Microlite plate, and the plate was sealed, mixed, and counted.

A blood sample (7 ml) was carefully layered over 5 ml PMN Cell Isolation Medium (Robbins Scientific) in a 15 ml round bottom centrifuge tube. The sample was centrifuged at 450-500 x g for 30-35 minutes in a swing out rotor at room temperature. After centrifugation, the top band of cells were removed and washed 3 times with PBS w/o calcium or magnesium. The cells were centrifuged at 400 x g for 10 minutes at room temperature. The cells were resuspended 8UBSπTUTE8HEEr(R .E26) in Macrophage Serum Free Medium (Gibco BRL) at a concentration of 2 million cells/ml. LPS Stimulation of Human PBMs : PBM cells (0.1 ml, 2 million/ ml) were co-incubated with 0.1 ml compound (10-0.41 μM, final concentration) for 1 hour in flat bottom 96 well microtiter plates. Compounds were dissolved in DMSO initially and diluted in TCM for a final concentration of 0.1% DMSO. LPS (Calbiochem, 20 ng/ml, final concentration) was then added at a volume of 0.010 ml. Cultures were incubated overnight at 37 °C. Supematants were then removed and tested by ELISA for TNF-a and ILl-b. Viability was analyzed using MTS. After 0.1 ml supernatant was collected, 0.020 ml MTS was added to remaining 0.1 ml cells. The cells were incubated at 37 °C for 2-4 hours, then the O.D. was measured at 490-650 nM. Maintenance and Differentiation of the U937 Human Histiocvtic Lymphoma Cell Line: U937 cells (ATCC) were propagated in RPMI 1640 containing 10% fetal bovine serum, 100 IU/ l penicillin, 100 μg/ml streptomycin, and 2 mM glutamine (Gibco) . Fifty million cells in 100 ml media were induced to terminal monocytic differentiation by 24 hour incubation with 20 ng/ml phorbol 12-myristate 13-acetate (Sigma). The cells were washed by centrifugation (200 x g for 5 min) and resuspended in 100 ml fresh medium. After 24-48 hours, the cells were harvested, centrifuged, and resuspended in culture medium at 2 million cells/ml. LPS Stimulation of TNF production by U937 Cells: U937 cells (0.1 ml, 2 million/ml) were incubated with 0.1 ml compound (0.004-50 μM, final concentration) for 1 hour in 96 well microtiter plates. Compounds were prepared as 10 mM stock solutions in DMSO and diluted in syasrnuTESHEEriwJtEse ) culture medium to yield a final DMSO concentration of 0.1% in the cell assay. LPS (E coli, 100 ng/ml final concentration) was then added at a volume of 0.02 ml. After 4 hour incubation at 37°C, the amount of TNF-α released in the culture medium was quantitated by ELISA. Inhibitory potency is expressed as IC50 (μM) .

Male Harlen Lewis rats [Sprague Dawley Co.] were used in this model. Each rat weighed approximately 300 g and was fasted overnight prior to testing. Compound administration was typically by oral gavage (although intraperitoneal, subcutaneous and intravenous administration were also used in a few instances) 1 to 24 hours prior to the LPS challenge. Rats were administered 30 μg/kg LPS [salmonella typhosa, Sigma Co.] intravenously via the tail vein. Blood was collected via heart puncture 1 hour after the LPS challenge. Serum samples were stored at -20 °C until quantitative analysis of TNF-α by Enzyme Linked- Immuno- Sorbent Assay ("ELISA") [Biosource] . Additional details of the assay are set forth in Perretti, M. , et al . , Br . J . Pharmacol . (1993), 110, 868-874, which is incorporated by reference in this application. Mouse Assay Mouse Model Of LPS-Induced TNF Alpha Production: TNF alpha was induced in 10-12 week old BALB/c female mice by tail vein injection with 100 ng lipopolysaccharide (from S. Typhosa) in 0.2 ml saline. One hour later mice were bled from the retroorbital sinus and TNF concentrations in serum from clotted blood were quantified by ELISA. Typically, peak levels of serum TNF ranged from 2-6 ng/ml one hour after LPS injection. The compounds tested were administered to fasted mice by oral gavage as a suspension in 0.2 ml of 0.5% methylcellulose and 0.025% Tween 20 in water at 1 hour or 6 hours prior to LPS injection. The 1 hour protocol allowed evaluation of compound potency at Cmax plasma levels whereas the 6 hour protocol allowed estimation of 8UBSπTUTESHEEr(RULE28) compound duration of action. Efficacy was determined at each time point as percent inhibition of serum TNF levels relative to LPS injected mice that received vehicle only. Additional results obtained using the above- described assays are set forth in Table 6 below. p38 assay and U937 cell assay results are expressed as IC 50 (μm) . Mouse-LPS assay results are expressed as percent inhibition. gUBSntU ESHEETlW tESfi) TABLE 6 8UBSπTUTESHEETCRULE2β) p38α in vitro assay results based on PHAS-I assay procedure p38α in vitro assay results based on EGFRP assay procedure SUBSnTUTESHEET(RULE26) Induction And Assessment Of Collagen-Induced Arthritis In Mice : Arthritis was induced in mice according to the procedure set forth in J.M. Stuart, Collagen Autoimmune Arthritis, Annual Rev . Immunol . 2:199 (1984), which is incorporated herein by reference. Specifically, arthritis was induced in 8-12 week old DBA/l male mice by injection of 50 μg of chick type II collagen (CII) (provided by Dr. Marie Griffiths, Univ. of Utah, Salt Lake City, UT) in complete Freund's adjuvant (Sigma) on day 0 at the base of the tail. Injection volume was 100 μl . Animals were boosted on day 21 with 50 μg of CII in incomplete Freund's adjuvant (100 μl volume). Animals were evaluated several times each week for signs of arthritis. Any animal with paw redness or swelling was counted as arthritic. Scoring of arthritic paws was conducted in accordance with the procedure set forth in Wooley et al . , Genetic Control of Type II Collagen Induced Arthritis in Mice: Factors Influencing Disease Suspectibility and Evidence for Multiple MHC Associated Gene Control., Trans . Proc . , 15:180 (1983). Scoring of severity was carried out using a score of 1-3 for each paw (maximal score of 12/mouse) . Animals displaying any redness or swelling of digits or the paw were scored as 1. Gross swelling of the whole paw or deformity was scored as 2. Ankylosis of joints was scored as 3. Animals were evaluated for 8 weeks. 8-10 animals per group were used. Preparation And Administration Of Compounds: The compounds tested on mice having collagen-induced arthritis were prepared as a suspension in 0.5% methylcelluose (Sigma, St. Louis, MO), 0.025% Tween 20 (Sigma) . The compound suspensions were administered by oral gavage in a volume of 0.1 ml b.i.d. Administration began on day 20 post collagen injection and continued SUBSπrUTESHEET(RULE26) daily until final evaluation on day 56. Scoring of arthritic paws was conducted as set forth above.

The active compounds of the present invention may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted to such a route, and in a dose effective for the treatment intended. The active compounds and composition may, for example, be administered orally, intravascularly (IV) , intraperitoneally, subcutaneously, intramuscularly (IM) or topically. For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, hard or soft capsule, lozenges, dispensable powders, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient . Examples of such dosage units are tablets or capsules. The active ingredient may also be administered by injection (IV, IM, subcutaneous or jet) as a composition wherein, for example, saline, dextrose, or water may be used as a suitable carrier. The pH of SυBSTTrUTESHEET(RULE2β) the composition may be adjusted, if necessary, with suitable acid, base, or buffer. Suitable bulking, dispersing, wetting or suspending agents, including mannitol and PEG 400, may also be included in the composition. A suitable parenteral composition can also include a compound formulated as a sterile solid substance, including lyophilized powder, in injection vials. Aqueous solution can be added to dissolve the compound prior to injection. The amount of therapeutically active compounds that are administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the severity of the inflammation or inflammation related disorder, the route and frequency of administration, and the particular compound employed, and thus may vary widely. The pharmaceutical compositions may contain active ingredients in the range of about 0.1 to 1000 mg, preferably in the range of about 7.0 to 350 mg. A daily dose of about 0.01 to 100 mg/kg body weight, preferably between about 0.1 and about 50 mg/kg body weight and most preferably between about 0.5 to 30 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day. In the case of skin conditions, it may be preferable to apply a topical preparation of compounds of this invention to the affected area two to four times a day. For disorders of the eye or other external tissues, e.g., mouth and skin, the formulations are preferably applied as a topical gel, spray, ointment or cream, or as a suppository, containing the active ingredients in a total amount of, for example, 0.075 to 30% w/w, preferably 0.2 to 20% w/w and most preferably 0.4 to 15% w/w. When formulated in an ointment, the active ingredients may be employed with either paraffinic or a water-miscible ointment base. SUBSrmJTESHEET(R £26} Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example at least 30% w/w of a polyhydric alcohol such as propylene glycol, butane- 1, 3 -diol , mannitol, sorbitol, glycerol, polyethylene glycol and mixtures thereof. The topical formulation may desirably include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethylsulfoxide and related analogs. The compounds of this invention can also be administered by a transdermal device. Preferably topical administration will be accomplished using a patch either of the reservoir and porous membrane type or of a solid matrix variety. In either case, the active agent is delivered continuously from the reservoir or microcapsules through a membrane into the active agent permeable adhesive, which is in contact with the skin or mucosa of the recipient. If the active agent is absorbed through the skin, a controlled and predetermined flow of the active agent is administered to the recipient. In the case of microcapsules, the encapsulating agent may also function as the membrane. The transdermal patch may include the compound in a suitable solvent system with an adhesive system, such as an acrylic emulsion, and a polyester patch. The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier, it may comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier (s) with or without stabilizer (s) make-up the so-called emulsifying wax, and 8UBSTmrrESHEET(R JE2e) the wax together with the oil and fat make up the so- called emulsifying ointment base which forms the oily dispersed phase of the cream formulations. Emulsifiers and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, and sodium lauryl sulfate, among others. The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the active compound in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus, the cream should preferably be a non- greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters may be used. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used. Formulations suitable for topical administration to the eye also include eye drops wherein the active ingredients are dissolved or suspended in suitable carrier, especially an aqueous solvent for the active ingredients. The anti-inflammatory active ingredients are preferably present in such formulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10% and particularly about 1.5% w/w. For therapeutic purposes, the active compounds of this combination invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered per os, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose. Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art. All patent documents listed herein are incorporated by reference.

SUBSπTϋTE8HEEr(RϋUE26) Description of parallel array synthesis methodology utilized to prepare compounds of Examples B-i, B-ii, and B-iii. Scheme B-l describes the parallel array reaction blocks that were utilized to prepare compounds of Examples B- 0001 through B-1574, and by analogy could also be used to prepare compounds of Examples B-1575 through B-2269. Parallel reactions were performed in multi-chamber reaction blocks. A typical reaction block is capable of performing 48 parallel reactions, wherein a unique compound is optionally prepared in each reaction vessel Bl. Each reaction vessel Bl is made of either polypropylene or pyrex glass and contains a frit B2 toward the base of the vessel. Each reaction vessel is connected to the reaction block valve assembly plate B3 via leur-lock attachment or through a threaded connection. Each vessel valve B4 is either opened or closed by controlling the leur-lock position or by the opening or closing of levers B5 within a valve assembly plate row. Optionally, solutions can be either drained or maintained above the vessel frits by leaving the valves in the opened position and controlling the back pressure beneath the valve assembly plate by control of inert gas flow through the inert gas inlet valve B6. The parallel reactions that are performed in these reaction blocks are allowed to progress by incubation in a jacketed, temperature controlled shaking station. Temperature control of the reaction chambers is effected by passing a heat-transfer liquid through jacketed aluminum plates that make contact with the reaction block eUBSmUTESHΞΞT(RULE26) mantle B7. Mixing is effected at the shaking station by either vertical orbital shaking of the up-right reaction block or by lateral shaking of the reaction block tilted on its side. Functionalized resins are optionally added to each reaction vessel Bl during the course of reaction or at the conclusion of the reaction. These functionalized resins enable the rapid purification of each reaction vessel product. Vacuum filtration of the reaction block apparatus by opening of the vacuum valve B8 allows purified products to be separated from resin-sequestered non-product species. Valve B8 is located on the bottom reaction block chamber BIO which houses the quadrant collection vial racks Bll. The desired products are obtained as filtrates in unique collection vials B9. Removal of solvent from these collection vials affords desired products. 8ϋBSπTϋlB8HEET(R JE26) Scheme B-2 illustrates the various utilizations of functionalized resins to purify reaction vessel products B22 prior to filtration from the fritted vessels Bl into collection vials B9. Said functionalized resins perform as 1) resin-bound reagents B12, which give rise to resin- bound reagent byproducts B13 ; 2) sequestrants B14 or B15 of excess solution-phase reactants B16 or B17 , respectively. Solution-phase reactants B16 and B17 contain inherent reactive functionality -rfi and -rf 2 8UBSrnimSHEET(R £28 which enable their chemoselective sequestration by the complementary reactive functionality -Crfi and -Crf 2 attached to resins B14 and B15; 3) sequestrants B18 of solution-phase byproducts B19. Byproduct B19 contains molecular recognition functionality -mr 2 which enables its chemoselective sequestration by the complementary functionality -Cmr attached to resin B18; 4) reaction- quenching resins B20 which give rise to quenched resins B21. Resin B20 contains functionality -Q which mediates reaction quenching (for instance, proton transfer) of product B22 to form a desired isolable form of product B22. Upon performing reaction quench, the resin B20 is converted to resin B21 wherein -q represents the spent functionality on resin B21 ; 5) sequestrants B23 of chemically-tagged reagents B24 and their corresponding reagent byproducts B25. The soluble reagent B24 contains a bifunctional chemical group, -tag, which is inert to the reaction conditions but is used to enable the post- reaction sequestration of B24 by the complementary functionality -Ctag attached to resin B23. Additionally, the soluble reagent byproduct B25, formed during the course of reaction, contains the same chemical function - tag that also enables its sequestration by resin B23. Additionally, some reactants B16, particularly sterically-hmdered reactants and/or electron deficient nucleophiles, contain poorly sequestrable functionality (rfl in this case is a poorly sequestable functionality) . These poorly sequestable reactants B16 can be transformed in si tu to more robustly sequestrable species B27 through their reaction with sequestration-enabling-reagents B26. B26 contain highly reactive, complementary functionality Crfi which reacts with B16 to form B27 in situ . The 8U8STΠUΓESHEEΓ(RULE26) bifunctional molecular recognition functionality, mr, contained within B26 is also present on the in si tu derivatized B27. Both B26 and B27 are sequestered by the complementary molecular recognition functionality attached to resin B28. By analogy, some reactions contain poorly sequestable byproducts B19 , wherein the molecular recognition functionality mr 2 in this case is not able to mediate the direct sequestration of B19 by the complementary functionality attached to resin B18. Similar use of the bifunctional sequestration-enabling- reagent B29 transforms B19 into the more readily sequestrable species B30. The imparted molecular recognition functionality, mr, present in B30 is readily sequestered by the complementary functionality, Cmr, attached to resin B31. In some reactions, multiple sequestration resins are utilized simultaneously to perform reaction purifications. Even resins containing incompatible (mutually reactive) functional groups can be used simultaneously because these resins scavenge complementary functionalized solution phase reactants, reagents, or byproducts from solution phase faster than resin cross-neutralization. Similarly, resins containing mutually reactive or neutralizing reaction-quenching functionality are able to quench solution phase reactants, products, or byproducts faster than resin cross-neutralization . 8UBSmUTE$HEEr(R JE26) Scheme B-2 C Denotes insoluble resin Scheme B3 describes the modular robotics laboratory environment that was utilized to prepare compounds of Examples B0001 through Bxxxx. Chemicals that are utilized in the robotics laboratory are weighed and then dissolved or suspended- into solvents at Station #1 (Automated Chemistry Prep Station) . Thus, solutions or suspensions of known molarity are prepared for use at the other robotics workstations. Station #1 also optionally bar-code labels each chemical solution so that its identity can be read by bar-code scanning at this and other robotics workstations. Reactions are initiated at the modular Stations #2 and #2 DUP. Station #2DUP is defined as a duplicate of Station #2 and is used to increase capacity within the robotics laboratory. A reaction block is mounted at Station #2 or #2 DUP. Also, racks containing reactants, reagents, solvents, and resin slurries are also mounted at Station #2 or #2 DUP. Under the control of a chemical 8UB8fmUTESHEET(RuUE26) informatics mapping file, reactions are initiated by the transfer of reactant solutions, reagent solutions, solvents, and/or resin slurries into each mounted reaction block vessel. The transfer of known volumes of solutions, suspensions, or solvents is mediated by syringes which control a one-up septum piercing/argon purging cannula, a wide-bore resin slurry-despensing cannula, or by a six-up cannula which can simultaneously deliver volumes to a row of six reaction vessels. The reaction block and/or chemical solution racks may be optionally cooled below room temperature during the chemical solution transfer operations. After the transfer of chemical solutions and solvents has been performed by Station#2 or #2DUP, incubation of the reaction block may occur while the reaction block is mounted at the robot station. Preferably, however, the reaction block is removed after all volume transfers are complete and the reaction block is brought to ambient temperature. The reaction block is transferred off-line to either a vertical- or lateral shaking Incubator Station #5. The Automated weighing/archival Station #3 performs the functions of weighing empty collection vials (to obtain tare weights of collection vials) and also performs the functions of weighing collection vials containing filtered, purified products (to obtain gross weights of collection vials) . After product-containing collection vials have been weighed (gross weight determinations) at workstation #3 , the collection vial products are optionally redissolved into an organic solvent at workstation #3. Transfer of solvents is accomplished with syringes which control a mounted one-up septum- piercing/argon purging cannula. Each product-containing SUBafTnUTE8HEET(RU E26) collection vial is prepared as a solution of known molarity as directed and recorded by the chemical informatics system. These product solutions may be subsequently mounted at Station #2 or #2DUP for subsequent reaction steps or taken to Station #7 or #7DUP for analytical processing. Rapid solvent evaporation of product-containing collection vials is accomplished by mounting the collection racks at Savant Automated Solvent Evaporation Stations #4, #4 DUP, or #4 TRIP, wherein #4DUP and #4TRIP are defined as a duplicate and a triplicate of Station #4 to increase the capacity for solvent removal within the robotics laboratory. Commercially available solvent removal stations were purchased from the Savant Company (model # SC210A speedvac unit equipped with model # RVT4104 vapor trap and model # VNlOO vapornet cryopump) . Stations #7 and #7DUP perform analytical processing functions. Station #7DUP is defined as a duplicate of Station #7 to increase capacity within the robotics laboratory. Product-containing collection racks are mounted at either of these stations. Each product- containing collection vial is then prepared as a solution of known molarity as directed and recorded by the chemical informatics mapping file. Optionally, this dissolution function is performed by prior processing of the collection vial rack at Station #3 as described above. Station#7 or #7DUP, under the control of the chemical informatics mapping file, transfers aliquots of each product vial into unique and identifable microtiter plate wells that are utilized to perform analytical determinations . 8UBSnTUreSHEEr(RUL£26) One such microtiter plate is prepared at . Station #7 or #7DUP for subsequent utilization at the Automated HPLC/Mass Spectrometer Station #8 or #8DUP. Station #8DUP is a duplicate of Station #8 to increase the analytical capacity of the robotics laboratory. Stations #8 and #8DUP are commercially available benchtop LC/Mass spec units purchased from Hewlett Packard (model HP1100 HPLC connected to HP1100 MSD (G1946A) mass spectrometer; this unit is also equipped with a model# G1322A solvent degasser, model # G1312A binary pump, a model # G1316A column heater, and a model # G1315A diode array detector. The HP unit has been interfaced with a commercially available autosampler rack (Gilson Company # 215 autosampler) . Station #8 or #8DUP is utilized for the determination of product purity and identity by performing high performance liquid chromatography (HPLC) and companion atmospheric pressure chemi-ionization (APCI) or electrospray mass spectrometry for molecular weight determination. Another microtiter plate is prepared at Station #7 or #7DUP for subsequent utilization at a commercially available flow-probe Varian NMR spectrometer Station #10 (Varian Instruments flow probe NMR, 300 MHz, interfaced with a commercially available Gilson 215 autosampler) . Proton, 13 -Carbon, and/or 19 -Fluorine NMR spectra are determined at this Station #10. Other microtiter plates are optionally mounted at Station #7 or #7DUP for the purpose of preparing product- containing plates for biological assays. Aliquots of product-containing collection vials are transferred to these biological assay microtiter plates under the control of the chemical informatics mapping file. Identity and amount of each transferred product is gyBSπTϋTE8*€ET(R £26 recorded by the chemical informatics system for retrieval by biologists who perform the biological assaying of products . The Fourier Transfrom InfraRed (FT-IR) Spectrometer Station #11 is utilized to analyze resins for the identity of organic functional groups chemically attached to these resins. The resins, as mentioned above, contain chemical functionality utilized as reagents, chemoselective sequestrants, or reaction quenching media for the workup and purification of the crude product mixtures contained within reaction block vessels. The robotics laboratory utilizes a commercially available FT- IR spectrometer purchased from Nicolet Instruments (model # MagnaIR 560 interfaced with an InspectIR microscope for resin mounting and positioning) . Scheme B-3 The lines interconnecting the modular Stations denote the transfer of chemical racks, reaction blocks, and/or collection vial racks from one modular Station to another. The ChemLib IT system is a composite of software running on the client's desktop and software running on a remote server. The ChemLib IT system is a client/server software application developed to support and document the data handling flow in the robotics laboratory described above. This IT system integrates the chemist with the robotics synthesis laboratory and manages the data generated by this processes. The software running on the server warehouses all the electronic data for the robotics chemistry unit. This SUrøπUTES»CEr(RυLE2 β ) server, a Silicon Graphics IRIX station v6.2 , runs the database software, Oracle 7 v7.3.3.5.0 , that warehouses the data. Connection from the client's desktop to the server is provided by Oracle's TCP/IP Adapter v2.2.2.1.0 and SQL*Net v2.2.2.1.0A. SQL*Net is Oracle's network interface that allows applications running on the client's desktop to access data in Oracles' database. The client's desktop is Microsoft Windows 95. The ChemLib IT system client software is composed of Omnis7 v3.5 and Microsoft Visual ,C-F+ v5.0. This composition on the client side is what is herein referred to as ChemLib. ChemLib communicates with the server for its data via Oracle's PL/SQL v2.3.3.4.0. These PL/SQL calls within ChemLib creates a network socket connection to Oracle's SQL*Net driver and the TCP/IP Adapter thereby allowing access to the data on the server. A "library" is defined as a composite number of wells, where each well defines a single compound. ChemLib defines a library in a module called the Electronic Spreadsheet . The Electronic Spreadsheet is then a composite of n-number of wells containing the components that are required to synthesize the compound that exist in each these well(s) . The chemist begins by populating the Electronic Spreadsheet with those components required for the compound synthesis. The identity and the availability of these components are defined in the Building Block Catalog module of ChemLib. The Building Block Catalog is a catalog of a listing of all reagents, solvents, peripherals available in the robotics laboratory. Upon selecting the components for each compound we also 8UBSπTUTESHEET(RϋUE26) declare the quantity of each component to be utilized. The quantity of each component can be identified by its molarity and volumetric amounts (ul) or by it's solid state form (mg) . Therefore a well in the Electronic Spreadsheet defines a compound that is identified by its components and the quantity of each of these components. The assembly or the synthesis of these components for each compound in the Electronic Spreadsheet is defined in the WS Sequence module of ChemLib. The Define WS Sequence module identifies the synthesis steps to be performed at the robotics workstations and any activities to be performed manually or off-line from the robotics workstation. With this module we identify which components from the Electronic Spreadsheet and the activity that should be performed with this component in the robotics laboratory. In the Define WS Sequence module the chemist chooses from a list of activities to be performed in the robotics laboratory and assembles them in the order in which they are to occur. The ChemLib system takes these set of activities identified, and with the component data in the Electronic Spreadsheet assembles and reformats these instructions into terminology for the robotics workstation use. This robotics terminology is stored in a 'sequence' file on a common server that is accessible by the robotics workstation. The robotics workstation performs the synthesis in a reaction block apparatus as described. Each well in the Electronic Spreadsheet is tracked and mapped to a unique location in the reaction block apparatus on the robotics workstation. The compound or product synthesized at the @UBSrnUTESCET(RaE26) robotics workstation in the reaction block is then captured into collection vials. The collection vials are first tarred then grossed on the robotics workstation after colLecting their products from the reaction block. These weights (tare and gross) are recorded into the ChemLib system with the Tare/Gross Session module. The Tare/Gross Session module then calculates the product or compound yields and its final mass. Preparation of the compound for analytical analysis and screening is defined by the Analytical WS Setup module in ChemLib. The Analytical WS Setup module identifies the dilution factor for each well in the Electronic Spreadsheet , based on the compound's product yield and the desired molar concentration. This identifies the quantity, in uL, to be transferred at the robotics workstation, to a specific location on the MTP (microtiter plate) to be sent for analysis and/or biological assaying. The mass spectrometric and HPLC results for each well are recorded and scored into the ChemLib system. The Dilute/Archive WS module further identifies each compound by mapping the compound's well from the Electronic Spreadsheet to a specific MX block location for long term storage and archival as part of the registration process. All communications between ChemLib and the robotics workstations are by ASCII files. These files are placed on a server by the ChemLib system that is accessible by 8UBSΠTUΓESHEEΓ(RULE26) the robotics workstations. Reports generated by the robotics workstations are also placed on the server where the ChemLib system can read these files to record the data generated. Each robotics workstation consists of robotics hardware by Bohdan Automation, Inc. Mundelein, Illinois, and a PC currently running Microsoft Windows for Workgroup v3.11 and Ethernet software. The robotics workstation PC is logged into the network for one-way communication that allows the workstation to access the server for file access only. General Scheme B4 Scaffold C-i with a primary amine functionality contained within the R 4 substituent is reacted in spatially addressed, parallel array reaction block vessels with excess of electrophiles R J -Q wherein Q is chloro, bromo, or an acid activating group including but not limited to N-hydroxysuccinimide . R J -Q includes acid chlorides, alkyl chloroformates , sulfonyl chlorides, activated esters of carboxylic acids, activated carbamates, and isocyanates. Reaction of scaffold C-i with R J -QAs effected in the presence of a tertiary amine base at room temperature in a mixture of a polar aprotic solvent and/or a halogenated solvent. As illustrated in Scheme B-4 the products of the general formulae B-i are isolated in purified form by addition of a carbonyl- functionalized resin B32 which covalently sequesters any unreacted primary amine scaffold C-i as resin-bound adduct B35, and also by the addition of a primary amine- functionalized resin B33 which covalently sequesters any remaining electrophile R J -Q from each reaction mixture as 8UBS !UϊESHEεr(RULES£} resin-bound adduct B34. Resin B33 also sequesters the HQ byproduct from the reaction mixture by proton transfer from solution-phase Base-HQ. Incubation at room temperature, filtration, rinsing of the resin cake, and concentration of the filtrates affords purified products B-i filtered away from resin-bound adducts B32, B33, B34, B35, and B36. Scheme B-4 Scheme B-5 specifically illustrates the derivatization of the primary amine-containing scaffold Cl to afford the desired products B-i in a parallel array synthesis format. In a parallel array synthesis reaction block, individual reaction products are prepared in each of multiple reaction block vessels in a spatially 8C©STπUTESHEET(RULE26) addressed format. A solution of the desired primary amine-containing scaffold Cl (limiting amount,) in dimethylformamide (DMF) is added to the reaction vessels followed by a 4.0 fold Ξtoichiometric excess solution of N-methylmorpholine in DMF. To each reaction vessel is then added the electrophiles : either a 2.0 fold stoichiometric excess when R J -Q is an acid chloride or alkyl chloroformate, or a 1.5 fold stoichiometric excess when R J -Q is a sulfonyl chloride, or a 1.25 fold Ξtoichiometric excess when R J -Q is an isocyanate. Excess electrophiles and N-methylmorpholine were used to effect more rapid and/or more complete conversion of scaffold Cl to products B-0001-B-0048 compared to reactions that do not utilize stoichiometric excesses of electrophiles and N-methylmorpholine. The reaction mixtures are incubated at ambient temperature for 2-3 h. Each reaction vessel is then charged with a large excess (15-20 fold stoichiometric excess) of the amine-functionalized resin B33 and the aldehyde-functionalized resin B32. The resin-charged reaction block is shaken vertically for 14-20 h on an orbital shaker at ambient temperature to allow optimum agitation of the resin-containing vessel mixtures. The excess electrophiles R J -Q and any unreacted scaffold amine Cl are removed from the reaction medium as insoluble adducts B34 and B37 respectively. In addition the N-methylmorpholine hydrochloride salt formed during the course of the reaction is also neutralized to its free base form by proton tranΞfer reaction to the amine-functionalized resin B33. Simple filtration of the insoluble resin- adducts B32, B33, B34 , B36, and B37 , rinsing of the resin cake with dichloroethane, and evaporation of the filtrates affords the desired products B-i in purified form. SUBS UTE»CEr(RUl£26) Scheme B-5 Scheme B-6 illustrates a general synthetic method involving the parallel array reaction of a scaffold C-ii containing a secondary amine functionality within the definition of the R 4 substituent. Each reaction vessel is charged with the secondary amine-containing scaffold C- ii, followed by the introduction of a stoichiometric excess of an optionally unique electrophile R L -Q into each vessel, wherein Q is chloro, bromo, or an acid activating group including but not limited to N-hydroxysuccinimide. R L -Q includes acid chlorides, alkyl chloroformates, ggBSπTϋTESHEEriRϋl£2 6 ) sulfonyl chlorides, activated esters of carboxylic acids, activated carbamates, and isocyanates . Reaction of Ξcaffold C-ii with R L -Q is effected in the presence of tertiary amine base at room temperature or elevated temperature in a mixture of a polar aprotics solvent and/or a halogenated solvent. After solution-phase reactions have progressed to afford crude product mixtures in each vessel, the products B-ii are isolated in purified form by the addition of the isocyanate-functionalized resin B38 which covalently sequesters remaining secondary amine scaffold C-ii as resin-bound adduct B39, and also by the addition of the primary amine-functionalized resin B33 which covalently sequesters remaining electrophile R-Q from each reaction vessel as resin-bound adducts B40. Resin B33 also sequesters the HQ byproduct in each vessel as B36, formed by proton transfer from solution-phaΞe Base-HQ. Incubation with these resins, either simultaneously or sequentially, followed by filtration, rinsing, and concentration of the filtrates affords purified products B-ii filtered away from resin-adducts B33, B36, B38, B39, and B40. SUBSTWUTE8HEEr(F%Λ££6) Scheme B-6 Scheme B-7 illustrates the conversion of the secondary- amine containing scaffold C-2 to the desired products B- ii . In a parallel array synthesis reaction block, individual reaction products are prepared in each of 48 multiple reaction block vessels. A solution of the Ξcaffold C-2 (limiting amount) in dimethylformamide (DMF) is added to the reaction vessels followed by a 4.0- fold stoichiometric excess solution of N-methylmorpholine in DMF. To each reaction vessel is then added an electrophile R L -Q as a dichloroethane (DCE) solution: either a 2.0 fold stoichiometric excess is used when R L -Q is an acid chloride or alkyl chloroformate, or a 1.5 fold Ξtoichiometric excess when R-Q is a Ξulfonyl chloride, or 1.25 fold Ξtoichiometric excess when R -Q is an isocyanate . The reaction mixtures are incubated at 8UBSΠTUTESHEEΓ(RULE26) ambient temperature for 2-6 h. Each reaction vessel is then charged with a large excess (15-20 fold stoichiometric excess) of the amine-functionalized resin B33 and the isocyanate-functionalized resin B32. The i resin-charged reaction block is shaken vertically for 14-20 h on an orbital shaker at ambient temperature to allow optimum agitation of the resin-containing vessel mixtures.

Resin B33 also sequesters the HQ byproduct in each vessel as B36, formed by proton transfer from solution-phase Base- HQ . Incubation with theΞe resins, followed by filtration and rinsing with solvent mixtures of DMF and/or DCE, > affords purified product solutions in collection vials filtered away from resin-adducts B33, B36, B38, B39, and B40. Concentration of filtrates affords purified products B-ii. aUBSmUTE8HEEr(RUlE26) Scheme B-7 B39 B36 Scheme B-8 illustrates another general synthetic method involving the parallel array reaction of a scaffold C-ii containing a secondary amine functionality within the definition of the R 4 substituent. Each reaction vessel is charged with the secondary amine-containing scaffold C- ii, followed by the introduction of a stoichiometric excesΞ of an optionally unique electrophile R L -Q into each vessel. Reaction of scaffold C-ii with R-Q is effected in the presence of tertiary amine base at room temperature or elevated temperature in a mixture of a polar aprotic solvent and/or a halogenated solvent. gU β giπUlESHEEURUUi*) Excess electrophiles and N-methylmorpholine are used to effect more rapid and/or more complete conversion of scaffold C-ii to products B-ii compared to reactions that do not utilize stoichiometric excesses of electrophiles and N-methylmorpholine. The reaction mixtures are incubated at ambient temperature for 2-8 h. Each reaction vessel is then charged with the sequeΞtration- enabling reagent phenylsulfonylisocyanate B41. This reagent B41 reacts with remaining secondary amine scaffold C-ii, converting C-ii to the in si tu-derivatized compound B42. SubΞequent incubation of these vessel mixtures with a large excess (15-20 fold stoichiometric excess) of the amine-functionalized resin B33 sequesters the solution-phaΞe species R L -Q, HQ, B41, and B42 as the resin-bound adducts B40, B36, B44 , and B43, respectively. The resin-charged reaction block is Ξhaken vertically for 14-20 h on an orbital shaker at ambient temperature to allow optimum agitation of the resin-containing vessel mixtures. Filtration of the insoluble resin- adducts B33, B36, B40, B43 and B44 and subsequent rinsing of the vessel resin-bed with DMF and/or DCE affords filtrates containing the purified products B-ii. Concentration of the filtrates affords the purified products B-ii. SUBSnrnUTESHEEr(RULE26) Scheme B-8 B44 Scheme B-9 illustrates the method of Scheme B-8 using scaffold C-2. A solution of the scaffold C-2 (limiting 8UBSπTUTESHEET(RU E26) amount) in dimethylformamide (DMF) is added to the reaction vessels followed by a 4.0-fold stoichiometric excess solution of N-methylmorpholine in DMF. To each reaction vessel is then added an electrophile R L -Q as a dichloroethane (DCE) solution: either a 2.0 fold Ξtoichiometric excess is used when R-Q is an acid chloride or alkyl chloroformate, or a 1.5 fold stoichiometric excess when R L -Q is a sulfonyl chloride, or a 1.25 fold stoichiometric excess when R L -Q is an isocyanate. The reaction mixtures are incubated at ambient temperature for 2-6 h. After solution-phase reactions have progressed to afford crude product mixtures, each reaction vessel is then charged with a dichloroethane solution of the sequestration-enabling reagent phenylsulfonylisocyanate B41. This reagent B41 reacts with remaining secondary amine scaffold C-2, converting C-2 to the in si tu-derivatized compound B45. Subsequent incubation of these vessel mixtures with a large excess (15-20 fold stoichiometric excess) of the amine-functionalized resin B33 sequeΞters the solution- phase species R L -Q, HQ, B41, and B45 as the resin-bound adducts B40, B36, B4 , and B46, respectively. The resin- charged reaction block is shaken vertically for 20 h on an orbital shaker at ambient temperature to allow optimum agitation of the resin-containing vessel mixtures. Filtration of the insoluble resin- adducts B33, B36, B40, B44 , and B46 and subsequent rinsing of the vessel resin- bed with DCE affords filtrateΞ containing the purified productΞ B-ii. Concentration of the filtrates affordΞ the purified products B-ii. SUBSmUTESHEET(RU-E26) B44 Another general method for the parallel array reaction block synthesis is illustrated in Scheme B-10 for the derivatization of the carboxylic acid-containing scaffold 8UBSTO nESHEEUBUl£«) C-iii. Scaffold C-iii with a free carboxylic acid functionality is reacted in spatially addressed, parallel array reaction block vessels with excesses of optionally different primary or secondary amines B47 in the presence of the polymer-bound carbodiimide reagent B48 and a tertiary amine base in a mixture of a polar aprotic solvent and/or a halogenated solvent. After filtration of each crude vessel product misture away from resins B48 and B49, each reaction mixture is purified by treatment with the sequeΞtration-enabling-reagent B50 ( fcetra- fluorophthalic anhydride) . The reagent B50 reacts with remaining excess amine B47 to afford the in si tu- derivatized intermediates B51 which contain carboxylic acid molecular recognition functionality. Subsequent incubation of each reaction mixture with a 15-20-fold stoichiometric excess of the primay amine-functonalized resin B33 sequesters B51, B50, and any remaining acid Ξcaffold C-iii as resin-bound adducts B52 , B53, and B54, respectively. Filtration of soluton-phase products B-iii away from these resin-bound adducts and rinsing of the resin beds with a polar aprotic Ξolvent and/or halogenated solvent affordΞ filtrateΞ containing purified products B-iii. Concentration of the filtrates affords purified B-iii. Scheme B-10 B 7 C-iii B-iii (remaining) 8UBS rTUTESHEET(Rϋ E26) Scheme B-ll illustrates the conversion of the acid containing scaffold C-49 to the desired amide products B- iii in a parallel ΞyntheΞiΞ format. A limiting amount of the scaffold C-49 is added as a Ξolution in dimethylformamide to each reaction vessel containing the polymer bound carbodiimide reagent B48 (5 fold stoichiometric excess). A solution of pyridine (4 fold stoichiometric excess) in dichloromethane is added to this slurry, followed by addition of an excess amount of a dimethylformamide Ξolution of a unique amine B47 (1.5 fold Ξtoichiometric excess) to each vessel . The parallel reaction block is then agitated vertically on an orbital Ξhaker for 16-18 h at ambient temperature and filtered to separate the solution phase product mixture away from resin-bound reagent B48 and resin-bound reagent byproduct B49. The reΞulting solutions (filtrates) containing a mixture of the desired amide products B-iii, excess amines B47 and any unreacted acid containing Ξcaffold C- 49, are treated with tetrafluorophthalic anhydride B50. B50 convertΞ the excess amines B47 in each filtrate vessel to its respective sequeΞtrable half acid form B51. After two h incubation time, an excess of the amine- functionalized resin B33 and dichloromethane solvent are added to each reaction vessel. The amine-containing resin B33 converts B51, any remaining B50, and any remaining C-49 to their resin-bound adductΞ B52, B53, and B55, respectively. The resin-charged reaction block is shaken vertically for 16 h on an orbital shaker at ambient temperature to allow optimum agitation of the resin-containing vessel mixtures. Filtration of the insoluble resin- adducts B33, B52, B53 , and B55 and subsequent rinsing of the vessel resin-bed with -SUBSrmjI£SHEET(RULE26) dimethylformamide affords filtrates containing the purified products B-iii.

A general ΞyntheΞis of pyridylpyrazole scaffolds C-i, C- ii, and C-iii is depicted in Scheme C-l. Step A: Picoline iΞ treated with a baΞe chosen from but not limited to n-butyllithium (n-BuLi) , lithium di-iso- propylamide (LDA) , lithium hexamethyldisilazide (LiHMDS) , potasΞium t-butoxide (tBuOK), or sodium hydride (NaH) in an organic solvent such as tetrahydrofuran (THF) , diethyl ether, t-butyl methyl ether, t-BuOH or dioxane from -78 °C to 50 °C for a period of time from 10 minutes to 3 hours. The metallated picoline Ξolution iΞ then added to a Ξolution of ester B56. The reaction is allowed to stir from 30 minutes to 48 hours during which time the temperature may range from -20 °C to 120 °C . The mixture is then poured into water and extracted with an organic solvent. After drying and removal of solvent the pyridyl monoketone B57 is isolated as a crude solid which can be purified by crystallization and/or chromatography. 8UBSTΠUTESHEEΓ(RULE26) Step B: A solution of the pyridyl monoketone B57 in ether, THF, tBuOH, or dioxane is added to a base chosen from but not limited to n-BuLi, LDA, LiHMDS, tBuOK, or NaH contained in hexane, THF, diethyl ether, t-butyl methyl ether, or t-BuOH from -78 °C to 50 °C for a period of time from ranging from 10 minutes to 3 hourΞ . An appropriately ΞubΞtituted activated ester or acid halide derived from R 4 -C0 2 H is then added as a solution in THF, ether, or dioxane to the monoketone anion of B57 while the temperature iΞ maintained between -50 °C and 50 °C . The reΞulting mixture iΞ allowed to Ξtir at the specified temperature for a period of time from 5 minutes to three hours. The reΞulting pyridyl diketone intermediate B58 is utilized without purification in Step C. Step C: The solution containing the pyridyl diketone B58 is quenched with water and the pH is adjuΞted to between 4 and 8 utilizing an inorganic or organic acid chosen from HOAc, H 2 S0 4 , HCl, or HN0 3 . The temperature during this Ξtep is maintained between -20 °C and room temperature. Hydrazine or hydrazine hydrate was then added to the mixture while maintaining the temperature between -20 °C and 40 °C for a period of 30 minutes to three hours. The mixture is then poured into water and extracted with an organic solvent. The pyridyl pyrazole C-i or C-ii is obtained as a crude solid which is purified by chromatography or crystallization. Step: D In some cases the pyridyl pyrazole C-i or C-ii is alkylated with Q-C (R A ) - (CH2) n C0 2 alkyl wherein Q is halogen. C-i or C-ii is treated with a baΞe chosen from NaH, NaOEt, KOtBu, or NEt 3 in an organic solvent such as THF, methylene chloride, dioxane, or DMF at temperatures between -20 °C and 150 °C and reaction times between 30 minuteΞ and 12 hours . The reΞulting alkylated pyridyl pyrazole ester iΞ then hydrolyzed to the acid by treament with NaOH or LiOH in aqueous/alcohol solvent mixtures or in THF/water solvent mixtures. Alternatively, the ester function is removed by treatment with an organic or inorganic acid if the alkyl residue is t-butyl . Acidification, followed by extraction with an organic solvent affords C-iii which may be purified by chromatography or crystallography. In some cases, regioisomeric alkylated productΞ C-iv are alΞO formed. The desired C-iii can be separated away from C-iv by chromatographic purification or by fractional crystallization.

Step A: 8 BSfi πE8t€ET(RϋLE2 β ) Picoline is added to a Ξolution of LiHMDS in THF at room temperature over a time period ranging from 30 minutes to 1 hour. The resulting solution is Ξtirred for an additional 30 minutes to 1 hour at room temperature. This solution is then added to neat ethyl p- fluorobenzoate B60 at room temperature over 1-2 h. The mixture is then allowed to stir at room temperature for 16-24 h. Equal portions of water and ethyl acetate are then added to the reaction and the mixture is partitioned in an extraction funnel. The organic layer is dried, filtered, and evaporated to give an oily solid. Hexanes are then added and the solid is filtered and waΞhed with cold hexanes leaving the pyridyl monoketone B61 for use in Step B. Step B: The pyridyl monoketone B61 iΞ added as a solution in THF to a flask maintained at room temperature which contains t-BuOK in a THF/ t-BuOH cosolvent. A yellow precipitate forms and stirring at room temperature is continued for 1-3 h. After this time, N-Cbz-protected glycine N- hydroxysuccinimide B62 is added dropwise at room temperature as a solution in THF over 1-3 h. This solution, containing crude diketone B63, is used directly in Step C. Step C:. The solution from step C is treated with water and the pH iΞ adjuΞted to between 6 and 7 with acetic acid. Hydrazine hydrate iΞ then added dropwise to the mixture as a solution in water over 30 minutes to lh at room temperature . Water and ethyl acetate are then added to the flask and the mixture is then partitioned in a separatory funnel. The organic layer is dried, filtered, and evaported to give a crude oil which is purified by 8UBSrmUTESHEET(RULE26) silica gel chromatography, giving rise to purified C- lCbz. Step: D The Cbz protecting group contained in compound C-lCbz is cleaved using hydrogen gaΞ under pressure and Pd-C in methanol Ξolvent.

The metallated picoline solution iΞ then added to a Ξolution of an appropriately activated ester analog of a carboxylic acid CbzNR H -(CH 2 ) n CR F (R G ) -C0 2 H or BocNR H -(CH 2 ) n CR F (R G ) -C0 2 H, preferably but not limited to the N-hydroxysuccinimide B64. The reaction is allowed to stir from 30 minutes to 48 hours during which time the temperature may range from -20 °C to 120 °C . The mixture is then poured into water and extracted with an organic solvent. After drying and removal of solvent the pyridyl monoketone B65 is isolated as a crude solid which can be purified by crystallization and/or chromatography. Step B: A solution of the pyridyl monoketone B65 in ether, THF, tBuOH, or dioxane is added to a base chosen from but not limited to n-BuLi, LDA, LiHMDS, tBuOK, or NaH contained in hexane, THF, ether, dioxane, or tBuOH from -78 °C to 50 °C for a period of time from 10 minutes to 3 hours. The anion sometimeΞ precipitateΞ as a yellow solid. An appropriately substituted activated ester such as the N-hydroxysuccinimide B66 is then added as a solution in THF, ether, or dioxane to the monoketone anion while the temperature is maintained between -50 °C and 50 °C . The resulting mixture is allowed to stir at the Ξpecified temperature for a period of time from ranging from 5 minuteΞ to 3 hourΞ . The resulting pyridyl diketone intermediate B67 is utilized without further purification in Step C. Step C: The Ξolution containing the pyridyl diketone B67 is quenched with water and the pH is adjusted to between 4 and 8 utilizing an inorganic or organic acid chosen from HOAc, H 2 S0 4 , HCl, or HN0 3 . The temperature during this step iΞ maintained between -20 °C and room temperature. Hydrazine or hydrazine hydrate is then added to the mixture while maintaining the temperature between -20 °C and 40 °C for a period of 30 minutes to three hours . The mixture iΞ then poured into water and extracted with an organic solvent. The pyridyl pyrazole C-vBoc or C-vCbz is obtained as a crude solid which is purified by chromatography or crystallization.

Step A: A Boc protected pyridylpyrazole B68 is treated with benzaldehyde in methylene chloride at room temperature in the presence of a drying agent for a period of time ranging from 1-24 h. Solvent is then evaporated and the resulting imine B69 is used in step B without further purification. Step B: The pyridylpyrazole imine B69 is dissolved in THF and stirred under nitrogen at temperatures ranging from -78 to -20 °C. A base such as LDA, n-BuLi, or LiHMDS is added dropwise to the mixture which is then stirred for an additional 10 minutes to 3 h. Two-five equivalents of an alklyating agent R F -Q are then added to the mixture and Ξtirring iΞ continued for several hours. The mixture iΞ then quenched with acid and allowed to warm to room temperature and Ξtirred several hours until cleavage of the Boc and the imine functions is complete.

Examples B-0001 through B-0048 To each reaction vessel (polypropylene syringe tubes fitted with a porous frit, closed at the bottom) of a parallel reaction apparatus was added 200 uL of dimethylformamide. A stock solution of the scaffold amine C-1 in dimethylformamide (0.1 M, 500 uL) was added to each reaction vessel followed by the addition of a stock solution of N-methylmorpholine in dimethylformamide (1.0 M. , 200 uL) . A stock solution of each of the electrophiles was then added to the appropriate reaction vessels: a) 500 uL of a 0.2 M solution of the acid chlorides in dichloroethane or b) 500 uL of a 0.2 M Ξolution of the chloroformates in dichloroethane or c) 313 uL of a 0.2 M Ξolution of the iΞocyanates in dichloroethane or d) 375 uL of a 0.2 M solution of the sulfonyl chlorides in dichloroethane. The parallel reaction apparatus was then orbitally shaken (Labline Benchtop orbital shaker) at 200 RPM at ambient 8UaSTπϋTESHEET(RaE26) temperature (23-30 °C) for a period of 2-3 h, under a gentle flow of nitrogen. At this time each reaction vessel was treated with approximately 250 mg of polyamine resin B33 (4.0 meq N/g resin) and approximately 100 mg of polyalde yde resin B32 (2.9 mmol/g resin). Each reaction vessel was diluted with 1 mL dimethylformamide and 1 L dichloroethane and the orbital shaking was continued at 200 RPM for a period of 14-20 h at ambient temperature. Each reaction vessel was then opened and the desired solution phase products Ξeparated from the inΞoluble quenched byproducts by filtration and collected in individual conical vialΞ . Each vessel was rinsed twice with dichloroethane (1 mL) and the rinsings were alΞo collected. The solutions obtained were then evaporated to dryness in a Savant apparatus (an ultracentrifuge equipped with high vacuum, scalable temperature settings and a solvent trap to condense the volatile solvent vapors) . The resulting amide, carbamate, urea and sulfonamide products were then weighed and characterized.

To each slurry was added a solution of pyridine in dichloromethane (0.2 M, 1000 uL) followed by a solution of a unique amine B47 (0.2 M, 375 uL) in dimethylformamide . The reaction mixtures were agitated on a Labline benchtop orbital shaker at 250 RPM for 16-20 h at ambient temperature. The reaction mixtures were filtered into conical vials and the polymer was washed with 1.5 mL of dimethylformamide and 2.0 mL of dichloromethane. The filtrates were evaporated to dryness in a Savant apparatus and dimethylformamide (350 uL) was added to each conical vial to dissolve the residue. A solution of tetrafluorophthalic anhydride (1.0 M, 150 uL) in su B smxresHEET Jua β *) dimethylformamide was added to the reconstituted conical vials and the mixture incubated for 2 hours at ambient temperature. Polyamine polymer B33 (4.0 meq N/g resin, 250 mg) and 1.0 mL dichloromethane was then added to the reaction mixture in each conical vial. After agitating the reaction mixtures for 16 h at 250 RPM on an orbital shaker at ambient temperature, the mixtures were filtered through a polypropylene syringe tube fitted with a porous frit. The polymers were washed twice with dimethylformamide (1.0 mL each) and the filtrates and washings collected in conical vials.
