Nucleophilic Aromatic Substitution of Methacrylamide Anion and Its Application to the Synthesis of the Anticancer Drug Bicalutamide
Alkylsulfone-containing trisubstituted cyclohexanes as potent and bioavailable chemokine receptor 2 (CCR2) antagonists
We describe novel alkylsulfones as potent CCR2 antagonists with reduced hERG channel activity and improved pharmacokinetics over our previously described antagonists. Several of these new alkylsulfones have a profile that includes functional antagonism of CCR2, in vitro microsomal stability, and oral bioavailability. With this improved profile, we demonstrate that two of these antagonists, 2 and 12, are orally efficacious in an animal model of inflammatory recruitment
Biphenylsulfonamide Endothelin Receptor Antagonists. 2. Discovery of 4‘-Oxazolyl Biphenylsulfonamides as a New Class of Potent, Highly Selective ET A
Pyrazolo-pyrimidines: a novel heterocyclic scaffold for potent and selective p38 alpha inhibitors
The synthesis and structure-activity relationships (SAR) of p38 alpha MAP kinase inhibitors based on a pyrazolo-pyrimidine scaffold are described. These studies led to the identification of compound 2x as a potent and selective inhibitor of p38 alpha MAP kinase with excellent cellular potency toward the inhibition of TNFalpha production. Compound 2x was highly efficacious in vivo in inhibiting TNFalpha production in an acute murine model of TNFalpha production. X-ray co-crystallography of a pyrazolo-pyrimidine analog 2b bound to unphosphorylated p38 alpha is also disclosed

The discovery of (R)-2-(sec-butylamino)-N-(2-methyl-5-(methylcarbamoyl)phenyl) thiazole-5-carboxamide (BMS-640994)-A potent and efficacious p38alpha MAP kinase inhibitor
A novel structural class of p38alpha MAP kinase inhibitors has been identified via iterative SAR studies of a focused deck screen hit. Optimization of the lead series generated 6e, BMS-640994, a potent and selective p38alpha inhibitor that is orally efficacious in rodent models of acute and chronic inflammation
