Synthesis and evaluation of 2-anilino-3-phenylsulfonyl-6-methylpyridines as corticotropin-releasing factor1 receptor ligands

A novel series of 2-anilino-3-phenylsulfonyl-6-methylpyridines was synthesized and evaluated as corticotropin-releasing factor receptor ligands. Structure–activity relationship studies focused primarily on optimization of the 3-phenylsulfonyl group. Compounds within this series were identified which showed potent binding affinity for the CRF1 receptor. Selected compounds were examined in a rat pharmacokinetic study and were found to have oral bioavailabilities ranging from 16 to 35%.
