A total of 14 of 1,5-disubstituted tetrazole derivatives were prepared by reacting appropriate thiourea and sodium azide in the presence of mercury (II) chloride and triethylamine. All compounds were evaluated in vitro for their antimicrobial activity. Derivatives 10 and 11 showed the highest inhibition against Gram-positive and Gram-negative strains (standard and hospital strains). The observed minimal
通过使合适的硫脲和叠氮化钠在氯化汞(II)和三乙胺存在下反应,总共制备了14种1,5-二取代的四唑衍生物。在体外评估所有化合物的抗微生物活性。衍生物10和11对革兰氏阳性和革兰氏阴性菌株(标准菌株和医院菌株)显示出最高的抑制作用。观察到的最小抑菌浓度值在1–208μM(0.25–64μg/ ml)的范围内。1,5-四唑衍生物10和11对分离自金黄色葡萄球菌的促旋酶和拓扑异构酶IV的抑制活性被研究了。分子对接研究对所有合成衍生物和参考环丙沙星进行了评估。此外,所选择的四唑(2,3,5,6,8,9,10和11),用于它们的细胞毒性进行了评价。所有测试的化合物对非细胞毒性的HaCaT和A549细胞(CC 50 ≤60μM)。
