series of 2,4-hexadienoic acid derivatives (S(1)-S(42)) has been synthesized and evaluated as antimicrobial agents against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans, and Aspergillus niger. Quantitative structure-activity relationship (QSAR) investigation using Hansch analysis was applied to find out correlation between antimicrobial activities with physicochemical properties
合成了一系列新的2,4-己二酸衍生物(S(1)-S(42)),并将其作为抗金黄色葡萄球菌,枯草芽孢杆菌,大肠杆菌,白色念珠菌和黑曲霉的抗菌剂进行评估。应用Hansch分析法进行定量构效关系(QSAR)研究,以发现抗菌活性与合成化合物的理化性质之间的相关性。各种理化指标和实验确定的不同微生物的最低抑菌浓度值分别用作自变量和因变量。QSAR结果表明,拓扑参数,尤其是分子连接性指数(chi(2),(0)chi(v),(2)chi(v))与抗菌活性2具有总体显着相关性,4-己二酸衍生物。训练集,交叉验证的r(2)和常规r值的统计结果为使用QSAR模型预测具有活性的分子提供了可靠性。
