A series of 5-fluorouracil benzimidazoles as novel type of potential antimicrobial agents were designed and synthesized for the first time. Bioactive assay manifested that some of the prepared compounds exhibited good or even stronger antibacterial and antifungal activities against the tested strains in comparison with reference drugs norfloxacin, chloromycin and fluconazole. Noticeably, 3-fluorobenzyl
首次设计和合成了一系列5-氟尿嘧啶苯并咪唑类新型潜在抗菌剂。生物活性测定表明,与参考药物诺氟沙星,氯霉素和氟康唑相比,某些制备的化合物对被测菌株表现出良好或什至更强的抗菌和抗真菌活性。值得注意的是,3-氟苄基苯并咪唑衍生物5c对啤酒酵母,MRSA和变形杆菌具有显着的抗菌活性,MIC值分别为1、2和4μg/ mL。实验研究表明,化合物5c可以有效插入小牛胸腺DNA中,形成化合物5c-DNA复合物,该复合物可能阻止DNA复制,从而发挥抗菌活性。
