In the present work, benzimidazole and 2-methylbenzimidazole derivatives were synthesized and evaluated for antimicrobial activity against Escherichia coli (Gram-negative bacteria), Staphylococcus aureus (Gram-positive bacteria) and Candida albicans (fungal stain). The structure of the synthesized compounds was confirmed by FTIR, 1H NMR and mass spectroscopy. Antimicrobial activity of all the synthesized compounds was carried out by Broth dilution method to determine MIC value. Compounds P2, P7 and P10 showed better antibacterial activity against Escherichia coli as compared to benzimidazole, 2-methylbenzimidazole and ampicillin. Compounds P8 and P12 showed better antibacterial activity against Staphylococcus aureus as compared to benzimidazole, 2-methylmenzimidazole and ampicillin. Compound P2 and P9 showed better antifungal activity against Candida albicans as compared to benzimidazole, 2-methylbenzimidazole and griseofulvin.
本研究合成了苯并咪唑和 2-甲基苯并咪唑衍生物,并评估了它们对大肠杆菌(革兰氏阴性菌)、金黄色葡萄球菌(革兰氏阳性菌)和白色念珠菌(真菌染色)的抗菌活性。傅立叶变换红外光谱、1H NMR 和质谱证实了合成化合物的结构。所有合成化合物的抗菌活性均采用肉汤稀释法测定 MIC 值。与苯并咪唑、2-甲基苯并咪唑和氨苄西林相比,化合物 P2、P7 和 P10 对大肠杆菌具有更好的抗菌活性。与苯并咪唑、2-甲基苯并咪唑和氨苄西林相比,化合物 P8 和 P12 对金黄色葡萄球菌具有更好的抗菌活性。与苯并咪唑、2-甲基苯并咪唑和格列齐芬相比,化合物 P2 和 P9 对白色念珠菌具有更好的抗真菌活性。
