In continuation of our efforts toward the discovery of potent non-nucleoside hepatitis B virus (HBV) inhibitors with novel structures, we have employed bioisosterism and hybrid pharmacophore-based strategy to explore the chemically diverse space of bioactive compounds. Cytotoxicity, anti-HBV antigen secretion activities and anti-HBV DNA replication activity were assayed with cell counting kit-8 (CCK-8)
在继续努力发现具有新颖结构的有效非核苷乙型肝炎病毒(HBV)抑制剂的过程中,我们采用了生物立体异构和基于混合药效团的策略来探索生物活性化合物的化学多样性空间。使用细胞计数试剂盒8(CCK-8),酶联免疫吸附测定(ELISA)和实时PCR分别测定细胞毒性,抗HBV抗原分泌活性和抗HBV DNA复制活性。一些新化合物能够在低微摩尔范围内抑制HBV DNA活性的复制。尤其是,化合物8u对HBV DNA复制表现出最有效的活性,IC50值为3.4μM。研究了这些新化合物的初步构效关系(SAR),
