摘要:
                                SAR and molecular modeling investigations on the potent and selective thrombin inhibitor 1b (CVS 1578) and related serine protease inhibitors led to the design of series 2a-g, featuring quaternary alpha-amino-alpha-benzyl-lactam scaffolds that serve as novel P-3-P-4 dipeptide mimics. The design, synthesis, and biological activity of these targets are presented. (C) 1997 Elsevier Science Ltd.
