exhibited excellent inhibitory activity against drug-resistant pathogenic fungi. Preliminary mechanism studies revealed that the compound 11b might play an antifungal role by inhibiting the activity of SE and CYP51. Notably compounds did not show the genotoxicity through plasmid binding assay. Finally, this study of molecular docking, ADME/T prediction and the construction of 3D QSAR model were performed
通过对角鲨烯环氧合酶(SE)和14α-脱甲基酶(CYP51)抑制剂药效团特征和双靶活性位点的分析,设计并合成了一系列具有酰胺-吡啶骨架的化合物,以治疗药物增加的发病率抗真菌感染。体外评价表明,这些化合物具有一定程度的抗真菌活性。MIC值在0.125-2μg/ ml范围内的最有效化合物11a,11b具有广谱抗真菌活性,并且对耐药性病原真菌表现出优异的抑制活性。初步的机理研究表明,化合物11b可能通过抑制SE和CYP51的活性而发挥抗真菌作用。值得注意的是,通过质粒结合试验,化合物未显示出遗传毒性。最后,进行了分子对接,ADME / T预测和3D QSAR模型构建的研究。这些结果可以指出进一步优化铅化合物的方向。
