As a continuation of our previous work, a series of new phenyl acrylamide derivatives (4Aa-g, 4Ba-t, 5 and 6a-c) were designed and synthesized as non-nucleoside anti-HBV agents. Among them, compound 4Bs could potently inhibit HBV DNA replication in wild-type and lamivudine (3TC)/entecavir resistant HBV mutant strains with IC50 values of 0.19 and 0.18 μM, respectively. Notably, the selective index value
作为我们先前工作的延续,设计并合成了一系列新的苯基丙烯酰胺衍生物(4Aa-g,4Ba-t,5和6a-c)作为非核苷类抗HBV剂。其中,化合物4Bs可以有效抑制野生型和拉米夫定(3TC)/恩替卡韦耐药HBV突变株中HBV DNA复制,IC 50值分别为0.19和0.18μM。值得注意的是,4Bs的选择性指数值高于526,表明安全性良好。有趣的是,不像核苷类似物3TC,4BS能显著禁止3.5kb的pgRNA表达。分子对接研究表明4B通过疏水,π-π和H键相互作用可以很好地适合HBV核心蛋白的二聚体-二聚体界面。考虑到强效的抗HBV活性,低毒性以及与核苷类抗HBV药物3TC不同的抗HBV机理,化合物4Bs有望成为开发新型非核苷类抗HBV治疗药物的有希望的线索,并值得进一步研究。
