Conformational restriction is a promising strategy in the development of DAPY-type non-nucleoside reverse transcriptase inhibitors (NNRTIs). Herein, eighteen thiophene-biphenyl-DAPY derivatives were designed and synthesized as potent HIV-1 NNRTIs in which halogen and methyl groups were introduced to explore the conformationally constrained effects. Molecular docking and dynamic simulation analysis
构象限制是开发DAPY型非核苷逆转录酶抑制剂(NNRTIs)的一种有前途的策略。本文中,设计并合成了十八种噻吩-联苯-DAPY衍生物,作为有效的HIV-1 NNRTIs,其中引入了卤素和甲基以探索构象约束效应。分子对接和动态模拟分析表明,联苯环不同位置的取代基引起不同的二面角和结合构象,进一步解释了它们的抗病毒活性。2'-氟和3'-氯取代可与RT酶的相邻残基形成静电或卤素键相互作用。2'-甲基有助于扩大联苯环的二面角,并位于一个充满空间的疏水口袋中。具有两个甲基的22和23对WT-1被WT HIV-1感染的MT-4细胞(分别为EC 50 = 14和17 nM)和RT酶(分别为EC 50 = 27和42 nM)表现出强大的生物学活性。特别是,23种药物的毒性比 伊曲韦林低得多(CC 50 = 264.19μM),选择性指数高(SI = 18,564)。综上所述,提出了进一步构筑DAPYs
