The novel benzimidazole derivatives (3, 5, 8, 9, 12–14, 18–41) were prepared in this paper and the antimicrobial activities of these compounds against Staphylococcus aureus, methicillin-resistant S. aureus (MRSA, standard and clinical isolates), Bacillus subtilis, Escherichia coli and Candida albicans were evaluated. Compounds 24–26 which have no substitution of N-1 position displayed better antibacterial
新颖的苯并咪唑衍生物(3,5,8,9,12 - 14,18 - 41)在本文中和对这些化合物的抗微生物活性来制备金黄色葡萄球菌,耐甲氧西林金黄色葡萄球菌(MRSA,标准和临床分离物),枯草芽孢杆菌,大肠杆菌和白色念珠菌进行了评估。化合物24 – 26那些没有取代N-1位的药物对两种耐药细菌(MRSA,标准品和临床分离株)均显示出比标准品(环丙沙星,氨苄青霉素和苏木素)更好的抗菌活性。这些衍生物(24 - 26),2,5,6- trihalogenobenzimidazole类似物(8,12),5,6-二氯-2-氨基衍生物(13),和5-氯-2-(4-苄氧基苯基)苯并咪唑(35)表现出最强的抗菌活性,MIC 3.12μg/ ml对金黄色葡萄球菌。
