brine‐shrimp bioassay was also carried out to study their in‐vitro cytotoxic properties and two compounds, 5h and 5m, possessing LD50 = 7.154×10–4 M and 5.782×10–4 M, respectively, displayed potent cytotoxic activity against Artemia salina. The presence of a chlorine group in the coumarin moiety, its effect on their antibacterial, antifungal, and cytotoxic activities is discussed. All newly synthesized
开发新型抗菌药物在现代制药行业中变得越来越重要。由 4-溴甲基香豆素 1a-e 合成了一系列新型 3-氯-4-[4-(2-oxo-2H-chromen-4-基甲氧基)苯基]-1-苯基氮杂环丁烷-2-ones 5a-o 和4-芳基亚氨基甲基苯酚 3a-c。筛选了这些化合物对两种革兰氏阳性菌(金黄色葡萄球菌和万古霉素耐药肠球菌)和两种革兰氏阴性菌(大肠杆菌和痢疾志贺氏菌)的体外抗菌活性以及对烟曲霉、白色念珠菌和青霉菌的抗真菌活性. 结果表明,化合物 5c、5f、5h、5j 和 5m 对一组微生物显示出极好的活性。还进行了盐水虾生物测定以研究它们的体外细胞毒性和两种化合物,5h 和 5m 分别具有 LD50 = 7.154×10-4 M 和 5.782×10-4 M,显示出对卤虫的有效细胞毒活性。讨论了香豆素部分中氯基团的存在及其对抗菌、抗真菌和细胞毒活性的影响。所有新合成的化合物均通过元素分析
