Citridone A (1), originally isolated as a potentiator of antifungal miconazole activity from a fungal culture broth, has a phenyl-R-furopyridone structure. Because of its unique ring structure, 11 derivatives were chemically synthesized and their biological activity was evaluated. Derivatives 17, 20 and 21 potentiated miconazole activity against Candida albicans. Furthermore, 1, 14, 20 and 21 were found to inhibit yellow pigment production in methicillin-resistant Staphylococcus aureus.
Citridone A (1) 最初是作为抗真菌咪康唑活性的增强剂从真菌培养液中分离出来的,具有苯基-R-呋喃并吡啶酮结构。由于其独特的环状结构,化学合成了11种衍生物并评估了它们的生物活性。衍生物 17、20 和 21 增强了咪康唑对抗白色念珠菌的活性。此外,还发现 1、14、20 和 21 可以抑制耐甲氧西林金黄色葡萄球菌中黄色素的产生。
