chemical space around the entrance channel of HIV-1 reverse transcriptase (RT), a series of novel indolylarylsulfones (IASs) bearing N-substituted piperidine at indole-2-carboxamide were identified as potent HIV NNRTIs by structure-guided scaffold morphing and fragment rearrangement. All the IASs exhibited moderate to excellent potency against wild-type HIV-1 with EC50 values ranging from 0.62 μM to 0.006 μM
为了进一步探索HIV-1逆转录酶(RT)入口通道周围的化学空间,通过结构引导支架将一系列在吲哚-2-甲酰胺上带有N-取代哌啶的新型吲哚基芳砜(IAS)鉴定为有效的HIV NNRTI。变形和片段重排。所有的国际会计表现出中度至对野生型优异效力HIV-1与EC 50值范围从0.62μM至0.006μM 8(EC 50 = 6 1nM)和18(EC 50 = 9 nM)被认为是最有效的化合物,其活性高于NVP和DLV,并达到EFV和ETV的相同数量级。此外,大多数化合物在低微摩尔至两位数纳摩尔浓度范围内保持高活性,抵御各种单一的HIV-1突变体(L100I,K103N,E138K,Y181C)和一个具有EC 50值的双重突变体(F227L / V106A)。特别地,8个显示出对L100I的出色效能(EC 50 = 17 nM,抗性是2.8倍),而18个对E138K突变体则相对更有效(EC
