We have synthesized and examined the antibacterial activity, toxicity and affinity towards bacterial type II topoisomerases of a series of 1,2,4-triazole-ciprofloxacin hybrids. A number of these compounds displayed enhanced activity against Gram-positive and Gram-negative bacteria when compared to ciprofloxacin. The toxic concentrations of the obtained derivatives, evaluated on HEK-293 cells using MTT assay, were much higher than concentrations required to produce antibacterial effect. Finally, the results of enzymatic studies showed that the analyzed compounds demonstrated other preferences as regards primary and secondary molecular targets than ciprofloxacin.
我们合成并研究了一系列 1,2,4-噁唑-环丙沙星杂合物的抗菌活性、毒性和对细菌II型拓扑异构酶的亲和力。这些化合物中有不少在抗击革兰氏阳性和革兰氏阴性细菌方面表现出比环丙沙星更强的活性。通过 MTT 试验评估得到的衍生物的毒性浓度远高于产生抗菌效果所需的浓度。最后,酶学研究结果表明,所分析的化合物在主要和次要分子靶标方面表现出与环丙沙星不同的偏好。
