A series of non-nucleoside reverse transcriptase inhibitors derived from indole-based α-amino acids were designed and synthesized. Their inhibitory activities were detected by a TZM-bl cell assay on HIV virus type HIV-1IIIB. The comprehensive understanding of the SAR was obtained by utilizing the variation of the substituents of the indole-based α-amino acids. From the screened compounds, the novel inhibitors 19 and 29 were identified to be highly potent candidates with EC50 values of 0.060 μM and 0.045 μM respectively (CC50 values of 109.545 μM and 49.295 μM and SI values of 1825.8 and 1095.4). In most cases, the variation of substituents at different positions had a significant effect on the potency of activities. The results also indicate that the indole-based α-amino acids as efficient NNRTIs displayed comparable anti-HIV-1 activities to the reference drug NVP. We hope the identification of these indole-based amino acids as efficient NNRTIs of RT could stimulate researchers to develop more diversified anti-HIV drugs.
设计并合成了一系列由吲哚基δ-氨基酸衍生的非核苷类逆转录酶抑制剂。通过 TZM-bl 细胞试验检测了它们对 HIV 病毒 HIV-1IIIB 型的抑制活性。通过改变吲哚基 δ±-氨基酸的取代基,对其 SAR 有了全面的了解。在筛选出的化合物中,新型抑制剂 19 和 29 被确定为高效力候选化合物,其 EC50 值分别为 0.060 μM 和 0.045 μM(CC50 值分别为 109.545 μM 和 49.295 μM,SI 值分别为 1825.8 和 1095.4)。在大多数情况下,不同位置的取代基对活性的效力有显著影响。研究结果还表明,吲哚基δ-氨基酸作为高效 NNRTIs 具有与参考药物 NVP 相当的抗 HIV-1 活性。我们希望这些吲哚基氨基酸被鉴定为 RT 的高效 NNRTIs 能激励研究人员开发出更多样化的抗 HIV 药物。
