angular pyran isoflavones. The antibacterial activities of 1–3 were also evaluated, and all of them displayed good antibacterial activity against Gram-positive bacteria. Among them, 2 was the most potent one against MRSA, with a MIC value of 2 μg/mL, and the SEM assay indicated that the bacterial cell membranes of both MRSA and E. faecalis could be disrupted by 2. These findings suggest that this type of
异黄酮是一类天然产物,具有多种有趣的生物特性,包括抗氧化、保肝、抗菌和抗炎活性。 Scandenone (1)、osajin (2) 和 6,8-diprenylgenistein (3) 是天然异戊二烯异黄酮,具有相同的多酚骨架。本研究以关键中间体15为原料合成天然异黄酮1-3,建立了直链和角吡喃异黄酮的立体选择性合成方法。还对1-3的抗菌活性进行了评价,它们均对革兰氏阳性菌表现出良好的抗菌活性。其中,2是对MRSA最有效的一种,其MIC值为2 μg/mL,SEM分析表明2可以破坏MRSA和粪肠球菌的细菌细胞膜。这些结果表明,异黄酮类型可以作为开发治疗革兰氏阳性细菌感染的新型抗菌剂的先导。
