中文摘要：

采用新开发的ff12SB力场在NVIDIACUDAGPU上对HIV-1蛋白酶的活性位抑制剂体系和异位抑制剂体系分别进行了100ns的长时间分子动力学模拟，并用MM—PB／GBSA方法计算了活性位点抑制剂TL-3与HIV-1蛋白酶的结合自由能。异位抑制剂体系中分子片段2-甲基环己醇结合在Exo位，有利于抑制剂被束缚在活性位点附近。异位抑制剂体系中抑制剂TL-3与蛋白酶的结合自由能为-85．78kcal／mol，活性位抑制剂体系中为-79．45kcal／mol。这些结果有助于深入了解HIV-1PR的动力学过程，为设计新型强效抑制剂提供了新见解。

英文摘要：

We performed t00 nanosecond molecular dynamics simulation for the allosteric inhibitor system and active site inhibitor system of HIV-1 protease on NVlDIA CUDA GPU with new developed force field ff12SB. We also calculated the bind free energy of inhibitor TL-3 and HIV-1 protease with MM-PB/GBSA. Exo site binded fragment 2-methylcyclohexanol is favorable for the binding of inhibitor near the site. The bind free energy of inhibitor TL-3 and protease is - 85.78 kcal/mol in allosteric inhibitor system and - 79.45 kcal/mol in active site inhibitor system. These results are benefit for the deep learning of the dynamics process of HIV-1 PR, which provides important guidelines for the design of new strong inhibitors.
