A series of new coumarin-based 1,2,4-triazole derivatives were designed, synthesized and evaluated for their antimicrobial activities in vitro against four Gram-positive bacteria (Staphylococcus aureus, MRSA, Bacillus subtilis and Micrococcus luteus), four Gram-negative bacteria (Escherichia coli, Proteus vulgaris, Salmonella typhi and Shigella dysenteriae) as well as three fungi (Candida albicans
设计,合成和评估了一系列新的基于香豆素的1,2,4-三唑衍生物,它们在体外对四种革兰氏阳性细菌(金黄色葡萄球菌,MRSA,枯草芽孢杆菌和黄球微球菌),四种革兰氏阴性细菌具有体外抗菌活性。细菌(大肠杆菌,寻常变形杆菌,伤寒沙门氏菌和痢疾志贺菌)以及三种真菌(白色念珠菌,酿酒酵母和烟曲霉)。)的两倍连续稀释技术。生物活性测定表明,与参考药物依诺沙星,绿霉素和氟康唑相比,一些合成的香豆素三唑显示出相当甚至更好的抗菌和抗真菌功效。香豆素双三唑化合物显示出比其相应的单三唑衍生物更强的抗菌和抗真菌功效。
