New benzimidazole derivatives were synthesized and assessed for antimicrobial efficacy toward Escherichia coli, Bacillus cereus, Staphylococcus aureus, Candida albicans and Aspergillus fumigatus 293. Results indicated that compounds 3c and 3n have promising activity toward S. aureus, whereas 3i exhibited remarkable efficacy toward B. cereus. Moreover, compound 3c was proved to be the most active antifungal
合成了新的苯并咪唑衍生物,并评估了其对大肠杆菌,蜡状芽孢杆菌,金黄色葡萄球菌,白色念珠菌和烟曲霉293的抗菌功效。结果表明,化合物3c和3n对金黄色葡萄球菌具有良好的活性,而3i则对B.表现出显着的功效。蜡状。此外,化合物3c被证明是针对白色念珠菌的最具活性的抗真菌类似物。另一方面,3n对烟曲霉293表现出最高的活性。还测试了相同化合物对紫细菌ATCC 12472的抗群体感应活性,而化合物3c-f,3i-k和3m-o表现出可接受的活性。这些化合物对肝癌(HepG2)的体外抗肿瘤测试,结肠癌(HCT-116)和乳腺癌(MCF-7)细胞系显示,化合物3p对三种测试细胞系的功效最高。此外,3f,3m和3n对所有测试的细胞系均显示出有希望的活性。认为化合物3f,3m,3n和3p具有针对EAC细胞的体内抗肿瘤活性。评估了活性抗微生物和抗肿瘤类似物3a,3c,3f,3i-k,3m,3n和3p的DNA结
