Following on our initial discovery of S-CN-DABOs as non-nucleoside reverse transcriptase inhibitors (NNRTIs), a series of novel S-N3-DABO derivatives F1-F31 were developed by substituting the cyano group of S-CN-DABOs with azide group. Some of these compounds were conferred significantly increased potency against wild-type HIV-1 and clinically observed mutant strains. Remarkably, the best compound
继我们最初发现S -CN- DABOs作为非核苷类逆转录酶抑制剂 (NNRTIs) 之后,通过将S -CN - DABOs的氰基取代为叠氮基团。其中一些化合物对野生型 HIV-1 和临床观察到的突变株具有显着增强的效力。值得注意的是,与感染野生型 HIV-1 的 MT-4 细胞相比,最好的化合物F10的效力提高了 7 倍 (EC 50 = 0.053 μM),选择性提高了 12.5 倍 (SI = 6818)母体化合物B1 (EC 50 = 370 纳米,SI = 547)。F10对测试突变株的抗 HIV-1 活性显着增强。对于野生型逆转录酶,它的效力 (IC 50 = 0.080 μM) 是B1 (IC 50 = 1.51 μM) 的大约 19 倍。未发现该类似物在单剂量F10 (1.0 g/kg) 后对 hERG、CYP 和急性毒性具有显着抑制作用。
