Based on the structure of HIV-1 gp41 binding site for small-molecule inhibitors, optimization of lead 2 resulted in the discovery of a new series of 2,5-dimethyl-3-(5-(N-phenylrhodaninyl)methylene)-N-(3-(1H-tetrazol-5-yl)phenyl)pyrrole compounds with improved anti-HIV-1 activity. The most active compounds 13a and 13j exhibited significant potency against gp41 6-HB formation with IC50 values of 4.4
基于HIV-1 gp41的结合位点的结构为小分子抑制剂,铅优化2产生了一系列新的2,5-的发现-二甲基-3-(5-(Ñ -phenylrhodaninyl)亚甲基)- ñ -具有改善的抗HIV-1活性的(3-(1H-四唑-5-基)苯基)吡咯化合物。活性最高的化合物13a和13j对gp41 6-HB的形成具有显着的效力,IC 50值为4.4和4.6μM,对HIV-1在MT-2细胞中的EC-1复制具有EC 50 值分别为3.2和2.2μM,从而为开发靶向gp41的高效小分子HIV融合抑制剂提供了新的起点。
