A series of 22 benzimidazoles, having several substituents on the azole and benzene nuclei, were prepared and evaluated in vitro for antimicrobial activity. At first 2‐chloro or 2‐chloromethyl‐5(6)‐substituted‐1H‐benzimidazoles were synthesized, which were then substituted at C‐2 with several piperazine or piperidine derivatives. The antibacterial activity of these compounds against Staphylococcus
制备了一系列 22 种苯并咪唑,在唑核和苯核上具有多种替代物,并在体外评估了其抗菌活性。首先合成2-氯或2-氯甲基-5(6)-取代的-1H-苯并咪唑,然后在C-2处用几种哌嗪或哌啶衍生物取代。这些化合物对金黄色葡萄球菌、枯草芽孢杆菌、大肠杆菌和铜绿假单胞菌的抗菌活性,以及对白色念珠菌、星状念珠菌、近平滑念珠菌和假热带念珠菌的抗真菌活性被确定为 MIC 值。由于化合物12表现出良好的活性,为了阐明C-1处取代基对活性的影响,制备了C-1处具有乙基、烯丙基、苄基和对氟苄基取代基的苯并咪唑衍生物,
