insight into the anti-HIV efficacy of MKC-442 analogues (1-(alkoxymethyl)-6-benzyluracils), a new series of compounds was synthesized and evaluated for inhibition of HIV-1 replication. The modifications include a reactive center such as an aldehyde or an epoxide substituted at the benzyl group. It was believed that such reactive groups could improve the activity against HIV for the Y181C mutant by forming
为了更深入地了解MKC-442类似物(1-(烷氧基甲基)-6-苄基尿嘧啶)的抗HIV功效,合成了一系列新化合物并评估了其对HIV-1复制的抑制作用。所述修饰包括反应性中心,例如在苄基上取代的醛或环氧化物。据信,这种反应性基团可以通过与疏水口袋中的半胱氨酸中的巯基形成共价键而提高针对Y181C突变体的针对HIV的活性。不幸的是,在基于细胞的测定中对于此类化合物针对野生型HIV仅发现中等活性,而对Y181C突变体没有活性。然而,发现相应的肟和在苄基中具有丁烯基和烯丙氧基取代基的前体分子具有更高的活性。一些氨基 还合成了 DABO 和 S - DABO 类似物,但发现它们对HIV无活性。
