摘要: 目的研究黄酮类化合物对抑制重组人蛋白激酶CK2全酶的二维定量构效关系作用.方法采用密度泛函理论、分子力学和统计学相组合的方法,对一系列对重组人蛋白激酶CK2全酶具有抑制作用的黄酮类化合物进行二维的定量构效关系(2D-QSAR)的相关性进行分析.结果所建立的2D-QSAR方程具有较好的回归性(R2达到0.829).结论黄酮类化合物分子的最高占据轨道的能量(EHOM)O对重组人蛋白激酶CK2全酶的抑制活性起着关键的作用,同时,黄酮类化合物分子的体积大小也对CK2的抑制活性起着重要的作用.Abstract: Objective To establish a two-dimensional quantitative structure-activity relationship(2D-QSAR)model for predicting the inhibitory activities of flavonoids on recombinant human protein kinase CK2 holoenzyme.Method 2D-QSAR study was performed in a series of flavonoids with inhibitory activities on recombinant human protein kinase CK2 holoenzyme by combination of density functional theory,molecular mechanics and statistics.Result The established 2D-QSAR model(Eq.1)showed a reasonable regressive performance(R2 ...
