The design and synthesis of tetrapeptide-based alpha-ketoamides containing prime side acid isosteres HCV NS3 protease inhibitors are described. Tetrazole, sulfonic acid, and N-sulfonylcarboxamids were demonstrated to be efficient carboxylic acid replacements. Further optimization yielded a series of potent HCV NS3 protease inhibitors with IC(50) of 0.020-0.060 microM.
描述了基于四肽的α-酮酰胺的设计和合成,这些α-酮酰胺含有酸侧链等位
基因HCV
NS3蛋白酶抑制剂。已证明
四唑,
磺酸和N-磺酰基甲酰胺是有效的
羧酸替代品。进一步的优化产生了一系列有效的HCV 蛋白酶抑制剂,IC(50)为0.020-0.060 microM。
