Screening of new non-nucleoside reverse transcriptase inhibitors of HIV-1 based on traditional Chinese medicines database

HIV-1 RT is an important target for the treatment of AIDS.There are two major classes of antiviral agents that inhibit HIV-1 RT have been identified,nucleoside RT inhibitors(NRTIs) and non-nucleoside RT inhibitors(NNRTIs).In this report,a noval class of non-nucleoside compound with potential RT inhibitory activity were found from the traditional Chinese medicines database (TCMD) using a combination of virtual screening,docking,molecular dynamic simulations,where results were ranked by scoring function of...     

Syntheses of new difluoromethylene benzoxazole and 1,2,4-oxadiazole derivatives, as potent non-nucleoside HIV-1 reverse transcriptase inhibitors

In an effort to prepare new fluorine-containing compounds, which are active against HIV, several chemical modifications of a series of benzoxazole and 1,2,4-oxadiazole-CF₂CHOHAr derivatives were carried out. The products (9-30) which all have one or two CF₂ groups were tested for activity against HIV-1; they were devoid of significant activity, one of them being cytotoxic.     

Pyridazines 92. Synthesis of dialkyldipyridazinodiazepinones as potential HIV‐1 reverse transcriptase inhibitors

Two methods for the preparation of dialkylsubstituted dipyridazino[4,3‐b:3′,4′‐e][1,4]diazepinones and dipyridazino[3,4‐b:3′,4′‐e][1,4]diazepinones are reported. The new compounds were evaluated for their inhibitory effects against the replication of human immunodeficiency virus [HIV‐1(III_B) and HIV‐2(ROD)] in MT‐4 cells.     

HIV-1逆转录酶抑制剂2-氨基6-苯磺酰基苄腈及其类似物活性OSAR研究

首先利用半经验AM I量子化学方法计算了54个2-氨基-6-苯磺酰基苄腈及其类似物的物理化学、电子结构、指示变量等共28个参数,然后使用偏最小二乘,穷举回归和混沌遗传乘法训练的人工神经网络方法建立了这些参数和其抑制H IV-1逆转录酶活性之间的定量构效关系模型,为设计、合成更高生物活性的该类化合物提供了理论参考。
