A series of lactam derivatives 1b-g featuring P4-o-alkoxycarbonylbenzylsulfonamide residues along with the potential P4-homosaccharin prodrug candidate 1h was prepared in order to probe the thrombin S3 specificity pocket. The synthesis and alkoxide-catalyzed ring opening of the novel homosaccharin intermediate 7 followed by subsequent elaboration delivered the targets 1b-h which were potent and selective
制备了一系列具有P4-邻烷氧基羰基苄基磺酰胺残基的内酰胺衍生物1b-g,以及潜在的P4-糖精蛋白前体候选药物1h,以探测凝血酶S3的特异性口袋。新型高糖精中间体7的合成和醇盐催化的开环,然后进行后续的精制,产生了目标1b-h,它们是有效的选择性凝血酶抑制剂。将介绍这些靶标的设计,合成和生物学活性。
