Thiazol and thiazolidinedione derivatives are known in the literature for presenting several biological activities, such as anti-diabetic, anti-inflammatory, antiparasitic, antifungal and antimicrobial activity. With this in mind, this study reports on the synthesis and antibacterial activity of thiazole (NJ) and thiazolidinedione (NW) derivatives, as well as their effects in association with norfloxacin
在文献中已知噻唑和噻唑烷二酮衍生物具有几种生物活性,例如抗糖尿病,抗炎,抗寄生虫,抗真菌和抗微生物活性。考虑到这一点,本研究报告了噻唑(NJ)和噻唑烷二酮(NW)衍生物的合成和抗菌活性,以及它们与诺氟沙星的关系,对金黄色葡萄球菌1199B(SA-1199B)中的NorA外排泵产生了作用。拉紧。在评估的14种化合物中,发现有9种增强诺氟沙星活性,而来自NJ系列的4种化合物促进诺氟沙星的MIC降低了三倍。使用分子对接测定法来确认大多数活性化合物的结合模式。在计算机研究中 评估了NJ系列化合物与NorA泵的相互作用效率。两个系列的衍生物对任何测试菌株均未显示出显着的固有抗菌活性(MIC> 1024μg/ mL)。但是,当与诺氟沙星联用时,NJ16和NJ17化合物将这种药物的MIC降低了三倍,并抑制了1199B菌株中的NorA泵。此外,一些NW(05、10、18、19和21)和NJ化合物(16
