Optimization of lead compounds I and 2 resulted in novel, selective, and potent thrombin inhibitors incorporating weakly basic heterobicyclic P-1-arginine mimetics. The design, synthesis, and biological activity of racemic thrombin inhibitors 17-29 and enantiomerically pure thrombin inhibitors 30-33 are described. The arginine side-chain mimetics used in this study are 4,5,6,7-tetrahydro-1,3-benzothiazol-2-amine, 4,5,6,7-tetrahydro-2H-indazole, and 2-imino-4,5,6,7-tetrahydro-1,3-benzothiazol-3(2H)-yl-amine.
