On the basis of our earlier molecular docking analysis, we designed and synthesized 5-((arylfuran/1H-pyrrol-2-yl)methylene)-2-thioxo-3-(3-(trifluoromethyl)phenyl)thiazolidin-4-ones (12ao) as HIV-1 entry inhibitors. Compounds 12ao effectively inhibited infection by both laboratory-adapted and primary HIV-1 strains and blocked HIV-1 mediated cell−cell fusion and gp41 six-helix bundle formation. Molecular docking analyses on two highly active inhibitors, 12b, containing a carboxylic acid group, and 12m, containing a tetrazole group, indicated that they both fit snugly into the hydrophobic cavity of HIV-1 gp41 from which each has important ionic interactions with lysine 574 (K574). By contrast, molecular docking of 12i, a less active compound containing a pyrrole instead of a furan ring, indicated a completely different orientation from 12b and 12m and missed critical interactions.

新型 5-((Arylfuran/1H-pyrrol-2-yl)methylene)-2-thioxo-3-(3-(trifluoromethyl)phenyl)thiazolidin-4-ones 作为 HIV-1 融合体的设计、合成和生物活性靶向 gp41 的抑制剂

在我们之前的分子对接分析的基础上,我们设计并合成了 5-((arylfuran/1 H -pyrrol-2-yl)methylene)-2-thioxo-3-(3-(trifluoromethyl)phenyl)thiazolidin-4- ( 12a - o ) 作为 HIV-1 进入抑制剂。化合物12a - o有效抑制实验室适应和原代 HIV-1 菌株的感染,并阻止 HIV-1 介导的细胞 - 细胞融合和 gp41 六螺旋束形成。两种高活性抑制剂12b12m 的分子对接分析含有四唑基团,表明它们都紧贴在 HIV-1 gp41 的疏水腔中,每个都与赖氨酸 574 (K574) 具有重要的离子相互作用。相比之下,12i 的分子对接,一种含有吡咯而不是呋喃环的活性较低的化合物,表明与12b12m 的取向完全不同,并且错过了关键的相互作用。
