基于结构的研究导致鉴定S-三苯甲基-L-半胱氨酸(STLC)支架的受限衍生物作为丙型肝炎病毒(HCV)NS 5 B聚合酶的候选抑制剂。合成了一组STLC衍生物,并研究了它们对HCV NS 5 B的活性。三种STLC衍生物9、F-3070和F-3065被鉴定为中度HCV NS 5 B抑制剂,IC 50值在22.3至39.7 μM之间。F-3070和F-3065在BHK-NS 5 B-FRLuc报告基因中显示出对细胞内NS 5 B活性的有效抑制,并且还在Huh 7/Rep-Feo 1b报告基因系统中抑制HCV RNA复制。结合模式研究表明,STLC支架可用于开发新的NS 5 B抑制剂,通过在三苯甲基苯基基团之一的进一步化学修饰。
Structure-based studies led to the identification of a constrained derivative of S-trityl-L-cysteine (STLC) scaffold as a candidate inhibitor of hepatitis C virus (HCV) NS5B polymerase. A panel of STLC derivatives were synthesized and investigated for their activity against HCV NS5B. Three STLC derivatives, 9, F-3070, and F-3065, were identified as modest HCV NS5B inhibitors with IC50 values between 22.3 to 39.7 μM. F-3070 and F-3065 displayed potent inhibition of intracellular NS5B activity in the BHK-NS5B-FRLuc reporter and also inhibited HCV RNA replication in the Huh7/Rep-Feo1b reporter system. Binding mode investigations suggested that the STLC scaffold can be used to develop new NS5B inhibitors by further chemical modification at one of the trityl phenyl group.
