中文摘要：
本文针对43个噻唑衍生物Fascin蛋白抑制剂,运用CoMFA（比较分子力场分析）以及CoMSIA（比较分子相似性指数分析）这两种经典的3D-QSAR方法,建立了CoMFA模型和CoMSIA模型,分别对其进行三维定量构效关系研究。CoMFA模型和CoMSIA模型的交叉验证系数q~2分别为0.731和0.846,相关系数r~2分别为0.969和0.926。这两种模型都显示出了比较好的预测性和稳定性。它们的三维等势图以及对接结果也证实了抑制剂活性和结构特征之间的关系,可以为今后设计研究新型Fascin抑制剂而提供了理论基础。
英文摘要：
In this paper, two typical 3D-QSAR methods of CoMFA （comparative molecular field analysis） and CoMSIA （comparative molecular similarity index analysis） models were applied to systematic investigate 43 thiazole derivatives as Fascin protein inhibitors, and the CoMFA and CoMSIA model were builted to carries on the three-dimensional quantitative structure-activity relationship studies. The coefficients of cross-validation q2 and non cross-validation r2 for CoMFA model were 0.731 and 0.846, for CoMSIA model were 0.969 and 0.926 respectively. Both model had good predictive capability and stability. The contour maps provided useful guidance for more potent Fascin inhibitors discovery.
