A novel series of 2,6-diphenoxypyridines has been designed to inhibit factor Xa, a serine protease strategically located in the coagulation cascade. The evolution from the photochemically unstable bisamidine (Z,Z)-BABCH to potent bisamidine compounds with a pyridine heterocycle as the core scaffold has been achieved. The most potent compound in the series, 6h, has a K-i for human factor Xa of 12 nM. The selectivity of 6h against bovine trypsin and human thrombin was greater than 90- and 1000-fold, respectively. Two proposed modes of binding of 6h Do factor Xa are made based on the crystal structures of 6h by itself and of 6h bound to bovine trypsin.

The synthesis of aromatic ring-based pentamidine analogues, in which the aliphatic bridge has been replaced by benzene, pyridine, or pyrimidine has been accomplished in two steps. Compounds containing benzene and pyridine as the central core of the molecule have demonstrated activity against PCP in culture. Copyright (C) 1996 Elsevier Science Ltd
