2,4-oxadiazole conjugate ester derivatives (7a–j) was synthesized. All the derivatives were evaluated for their in vitro antibacterial activity against Gram-positive (Enterococcus, Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Salmonella, Klebsiella and Escherichia coli) bacteria and their minimum inhibitory concentration (MIC) was determined. Some of the derivatives have shown significant
由于全球抗菌素耐药性的快速增长,最需要开发新的抗菌素药物。因此,在这种情况下,合成了一系列新颖的吡唑/ 1,2,4-恶二唑共轭酯衍生物(7a–j)。评价所有衍生物对革兰氏阳性菌(肠球菌,枯草芽孢杆菌和金黄色葡萄球菌)和革兰氏阴性菌(沙门氏菌,克雷伯菌和大肠杆菌)的体外抗菌活性,并确定其最低抑菌浓度(MIC)。一些衍生物已显示出显着的生物学活性,其效力可与标准药物链霉素相媲美。。此外,通过计算机方法预测了分子对接研究,ADMET的药代动力学特性(吸收,分布,代谢,排泄和毒性),分子特性和TOPKAT分析。体外和计算机模拟研究表明,在所有化合物中,化合物(7a)已显示出显着的生物学活性,且LibDock得分为162.751 kcal / mol。所有合成的衍生物通过FTIR,1 H NMR,13 C NMR和质谱确认。
