structure–activity relationship (QSAR) study using genetic function approximation technique (GFA) and docking study were performed to confirm the series of coumarin core TACE inhibitors. QSAR model have been evaluated internally and externally using test set prediction. Through docking study of each molecule, it is validated that the electrostatic descriptors from the QSAR equation could explain the importance
根据对接研究,设计了一系列基于香豆素的TACE抑制剂以结合在TACE酶的S1'口袋中。合成了十二个类似物,大多数化合物具有体外TACE酶抑制作用以及细胞TNF-α抑制作用。其中15μl通过以30mg / kg的剂量口服有效抑制血清TNF-α的产生。化合物15l在角叉菜胶模型中也显示出42%的良好口服生物利用度,并有效抑制爪水肿。使用遗传功能近似技术(GFA)进行了定量构效关系(QSAR)研究和对接研究,以确认一系列香豆素核心TACE抑制剂。QSAR模型已使用测试集预测在内部和外部进行了评估。通过对每个分子的对接研究,证实了QSAR方程中的静电描述符可以很好地解释S1'口袋和TACE抑制活性的重要性。
