A novel series of 1-[2-(diarylmethoxy)ethyl]-2-methyl-5-nitroimidazole (DAMNI) analogues were synthesized and tested in cell-based assays and in enzyme assays against HIV-1 recombinant reverse transcriptase (RT). Preparation of the new derivatives was performed by reacting the appropriate benzhydrols or the corresponding bromides with 1-(2-hydroxyethyl)-2-methyl-5-nitroimidazole or the 3-hydroxypropyl
合成了一系列新型的1- [2-(二芳基甲氧基)乙基] -2-甲基-5-硝基咪唑(DAMNI)类似物,并在基于细胞的检测和针对HIV-1重组逆转录酶(RT)的酶检测中进行了检测。新的衍生物的制备是通过使适当的苯甲醇或相应的溴化物与1-(2-羟乙基)-2-甲基-5-硝基咪唑或3-羟丙基同系物反应来进行的。几种化合物在亚微摩尔范围内显示抗HIV-1活性。结构活性关系研究表明,二芳基甲烷部分的一个苯环上的间位取代会强烈影响其抗病毒活性。在相同的苯环上的3,5-二取代导致衍生物效力降低。RT非核苷结合位点内的分子建模和对接研究证实,DAMNIs,与其他NNRTIs(例如TNK-651和delavirdine(BHAP U90152))相似,假定蝴蝶状构象似乎介于经典NNRTIs(例如奈韦拉平,HEPT,TBZ,TIBO和DABO)的中间, BHAP。特别地,二苯基甲烷部分模拟了机翼,而1-(2-甲基
