novel series of coumarin derivatives 6a-o, bearing isoxazole moieties were designed and synthesized. After that, they were evaluated for melanin synthesis in murine B16 cells and inhibitory effect on the growth of CA (Candida albicans), EC (Escherichia coli), SA (Staphylococcus aureus). It was found that eleven compounds (6b-f, 6j-o) showed a better activity on melanin synthesis than positive control
设计并合成了带有异恶唑部分的香豆素衍生物6a-o的新系列。之后,评估它们在鼠B16细胞中黑色素的合成以及对CA(白色念珠菌),EC(大肠杆菌),SA(金黄色葡萄球菌)生长的抑制作用。发现11种化合物(6b-f,6j-o)显示出比阳性对照(8-MOP)更好的黑色素合成活性。其中,化合物6d(242%)和6f(390%)分别比8-MOP(149%)具有近1.6倍和2.6倍的效力,被认为是抗-白癜风。七个卤素取代的化合物对CA表现出中等的抗菌活性。有趣的是6e-f和6l-m 苯上有两个卤素的苯甲酰胺显示出与两性霉素B相当的抗CA活性。B16细胞中黑色素合成的评估以及上述结构多样的衍生物对细菌的抑制作用也导致了构效关系的概述。
