5-dimethylpyrrole (NB-2) and N-(3-carboxy-4-hydroxyphenyl)-2,5-dimethylpyrrole (A12) target a hydrophobic pocket of HIV-1 gp41 and have moderate anti-HIV-1 activity. In this paper, we report the design, synthesis, and structure–activity relationship of a group of hybrid molecules in which the pocket-binding domain segment of the C34 peptide was replaced with NB-2 and A12 derivatives. In addition, the synergistic
小分子融合抑制剂N-(4-羧基-3-羟基苯基)-2,5-二甲基吡咯(NB-2)和N-(3-羧基-4-羟基苯基)-2,5-二甲基吡咯(A 12)靶HIV-1 gp41的疏水口袋,并具有中等的抗HIV-1活性。在本文中,我们报道了一组杂合分子的设计,合成和结构-活性关系,其中C34肽的口袋结合结构域区段被NB-2和A 12取代衍生品。此外,分析了小分子与肽部分之间的协同作用,并发现了具有新型支架的先导化合物。我们发现单独的非肽或肽部分对HIV-1介导的细胞间融合均显示弱活性,但结合物正确地产生了强大的协同作用。其中,缀合物Aoc-βAla-P26和Noc-βAla-P26在细胞-细胞融合测定中显示出低的纳摩尔IC 50值,并有效抑制了对T20敏感和耐药的HIV-1菌株。此外,新分子对蛋白酶K的消化表现出比T20和C34更好的稳定性。
