derivatives with dual structural conformations was designed through a molecular hybridization strategy and expected to bind into the non-nucleoside inhibitor binding pocket (NNIBP) of HIV-1 RT in a flexible manner. A cell-based antiviral screening assay showed that some compounds were active against both wild-type and drug-resistant mutant virus strains (K103N+Y181C RT) of HIV-1 (compound 10b3 with EC50 = 0
通过分子杂交策略设计了一系列具有双重结构构象的新型哌啶基氨基-二芳基嘧啶(pDAPY)衍生物,并有望以灵活的方式结合到HIV-1 RT的非核苷抑制剂结合口袋(NNIBP)中。基于细胞的抗病毒筛选试验表明,某些化合物对HIV-1(化合物10b3,EC 50 = 0.047和4.6μM,选择性指数= 10 )的野生型和耐药突变病毒株(K103N + Y181C RT)均具有活性。2145和22)。分子模拟研究表明化合物10b3可以维持两个RT /配体配合物与NNIBP的关键疏水相互作用和氢键。特别地,它可以同时占据蛋白质/溶剂界面和进入通道。探索具有双重结合构象的杂合分子可能会提供可选的化学支架,作为新型HIV-1逆转录酶抑制剂(HIV-1 NNRTIs)。
