Novel bicyclic lactam inhibitors of thrombin: potency and selectivity optimization through P1 residues
摘要:
Peptidomimetic inhibitors of thrombin lacking the important Ser195-carbonyl interaction have been prepared. The binding energy lost after the removal of the activated carbonyl was recaptured through a series of modifications of the PI residues of the bicyclic lactam inhibitors. Selected substituted compounds displayed useful pharmacological profiles both in vitro and in vivo. (C) 2001 Elsevier Science Ltd. All rights reserved.
