this study, a series of novel gossypol derivatives were synthesized and screened in vitro for their anti-HIV-1 and anti-H5N1 activities, respectively. Replacing the aldehyde groups of gossypol with some amino acids not only reduced the cytotoxicity but also enhanced the activities against HIV-1 and H5N1. Compounds 13–17 showed more potent activities against HIV-1 and H5N1 than the other gossypol derivatives
在这项研究中,合成了一系列新颖的棉酚衍生物,并在体外对其抗HIV-1和抗H 5 N 1活性进行了筛选。用某些氨基酸取代棉酚的醛基,不仅可以降低细胞毒性,而且还可以增强对HIV-1和H 5 N 1的活性。与其他棉酚衍生物相比,化合物13 – 17对HIV-1和H 5 N 1的活性更强。同时,这些化合物还对H 5 N 1表现出更强的活性。比1-金刚烷胺。棉酚衍生物中缺少COONa基团会导致抗HIV-1活性的丧失,这表明该基团可能在介导抗病毒活性中起重要作用。添加时间分析表明,化合物13 – 17具有与T20相似的抗HIV-1作用机理。分子建模分析表明,化合物13 - 17可能适合的gp41的疏水口袋内通过氢键网络,疏水性接触性强的静电相互作用。
