Viral infectivity factor (Vif) is protective against APOBEC3G (A3G)-mediated viral cDNA hypermutations, and development of molecules that inhibit Vif mediated A3G degradation is a novel strategy for blocking HIV-1 replication. Through optimizations of the central ring of N-(2-methoxyphenyl)-2-((4-nitrophenyl)thio)benzamide (RN-18), we found a potent compound 12c with EC50 value of 1.54 μM, enhancing
病毒感染因子(Vif)对APOBEC3G(A3G)介导的病毒cDNA超突变具有保护作用,而抑制Vif介导的A3G降解的分子的发展是一种阻断HIV-1复制的新策略。通过优化N-(2-甲氧基苯基)-2-((4-硝基苯基)硫基)苯甲酰胺(RN-18)的中心环,我们发现有效化合物12c的EC50值为1.54μM,从而进一步增强了抗病毒活性与非许可的H9细胞中的RN-18相比,高出150倍。12c通过抑制Vif功能来保护A3G免于降解。此外,12c抑制了具有相对较高活性的不同HIV-1临床菌株(HIV-1KM018,HIV-1TC-1和HIV-1WAN)和耐药菌株(NRTI,NNRTI,PI和FI)。用甘氨酸酰胺化12c得到前药13a,与12c相比,其水溶性提高了约2600倍。而且,图13a以0.228μM的EC 50值有效地抑制了病毒复制。这些结果表明前药13a是用于治疗AIDS的有前途的候选药物。
