Abstract New series of benzothiazole derivatives were designed and synthesized. The newly synthesized compounds were screened for their antibacterial activity against Escherichia coli, Staphylococcus aureus and Bacillus cereus. Compounds 6j and 6o showed the highest activity against E. coli and S. aureus. The antifungal activity of these compounds was also tested against Candida albicans and Aspergillus
摘要设计合成了一系列新的苯并噻唑衍生物。筛选新合成的化合物对大肠杆菌,金黄色葡萄球菌和蜡状芽孢杆菌的抗菌活性。化合物6j和6o显示出对大肠杆菌和金黄色葡萄球菌的最高活性。还测试了这些化合物对白色念珠菌和烟曲霉293的抗真菌活性。化合物4c,4g和6j显示出对白色念珠菌的最高活性。另外,化合物4a和6j显示出对烟曲霉293的有希望的活性。检查了相同的化合物对紫罗兰色杆菌ATCC 12472的抗群体感应活性,而化合物4a,6j和6p显示了中等活性。合成的化合物的体外细胞毒性测试是针对宫颈癌(Hela)和肾成纤维细胞癌(COS-7)细胞系进行的。结果表明,所有测试的化合物对两种细胞系的IC50值均> 50μmol/ L。还评估了化合物4a–c,5a,6g,h,6j,6l,6o和7c,d的分子特性,毒性,药物相似性和药物得分概况。
