细胞周期蛋白依赖性激酶Ⅱ(cyclin-dependent kinase 2,CDK2)是一种重要的治疗癌症的靶标.本文中采用分子动力学取样,运用MM-PBSA/GBSA两种方法计算了CDK2-NU6102复合物的绝对结合自由能.通过能量分解的方法考察了CDK2大分子主要残基与配体NU6102之间的相互作用和识别.

关键词: 分子动力学, MM-PBSA/GBSA, 结合自由能, CDK2, 抑制剂

The cyclin-dependent kinases play important roles in regulation of the cell cycle. Their inhibitors have entered clinical trials to treat cancer. In the paper, the absolute binding free energy of cyclin-dependent kinase 2 with a potent purine-base inhibitor NU6102 was calculated by molecular dynamics simulation with MM-PBSA/GBSA methods, and reasonable results were obtained. Furthermore, the interaction between CDK2 and NU6102 was evaluated by energy decomposition analysis.
