  Design and synthesis of Rho kinase inhibitors (I)

  摘要：

  Several structurally unrelated scaffolds of the Rho kinase inhibitor were designed using pharmacophore information obtained from the results of a high-throughput screening and structural information from a homology model of Rho kinase. A docking simulation using the ligand-binding pocket of the Rho kinase model helped to comprehensively understand and to predict the structure-activity relationship of the inhibitors. This understanding was useful for developing new Rho kinase inhibitors of higher potency and selectivity. We identified several potent platforms for developing the Rho kinase inhibitors, namely, pyridine, 1H-indazole, isoquinoline, and phthalimide. (C) 2004 Elsevier Ltd. All rights reserved.

  atom economy has been developed for the synthesis of N-aryl-N′-(4-pyridinyl)ureas. With cheap selenium as the catalyst, carbon monoxide (instead of phosgene) as the carbonyl reagent, N-aryl-N′-(4-pyridinyl)ureas can be obtained in a one-pot manner mostly in moderate to good yields via oxidative cross-carbonylation of 4-aminopyridine with a variety of aromatic amines in the presence of oxygen under atmospheric
