A new series of potential nonnucleoside inhibitors of HIV-1 reverse transcriptase (NNRTIs) based on the carbocyclic 5′-nor-uracil scaffold were designed and synthesized. Three different aspects of the scaffold were investigated: the effects of adding a linker between the carbocyclic and phenyl fragments, introduction of different substituents on the benzoyl residue and replacing the central carbocyclic ring with a benzyl group. Analogues of 2′,3′-dideoxy-2′,3′-didehydro-5′-nor-uridine, bearing 3,5-dichloro- or 3,5-dimethylbenzoyl groups, showed inhibitory activity against HIV-RT wild-type (IC50 5–10 μM) and mutants L100I (IC50 1.2–2.1 μM) and K103N (IC50 8–17 μM).
我们设计并合成了一系列基于碳环 5′-or-uracil 支架的新型潜在 HIV-1 逆转录酶非核苷抑制剂(NNRTIs)。对该支架的三个不同方面进行了研究:在碳环和苯基片段之间添加连接物、在苯甲酰基残基上引入不同取代基以及用苄基取代中心碳环的效果。带有 3,5-二氯或 3,5-二甲基苯甲酰基的 2′,3′-二脱氧-2′,3′-二脱氢-5′-去甲尿苷的类似物对 HIV-RT 野生型(IC50 5-10 μM)和突变体 L100I(IC50 1.2-2.1 μM)及 K103N(IC50 8-17 μM)具有抑制活性。
