N-terminal truncation of the hexapeptide ketoacid 1 gave rise to potent tripeptide inhibitors of the hepatitis C virus NS3 protease/NS4A cofactor complex. Optimization of these tripeptides led to ketoacid 30 with an IC50 of 0.38 microM. The SAR of these tripeptides is discussed in the light of the recently published crystal structures of a ternary tripetide/NS3/NS4A complexes.
六肽酮酸1的N端截短产生了丙型肝炎病毒NS3蛋白酶/ NS4A辅因子复合物的有效三肽抑制剂。这些三肽的优化产生了酮酸30,IC50为0.38 microM。鉴于最近公布的三元三元/ NS3 / NS4A配合物的晶体结构,讨论了这些三元的SAR。
