four undescribed fusaric acid derivatives, namely fusaricates H-K, and two undescribed γ-pyrone derivatives, named fusolanones A-B, as well as a known compound fusaric acid, were isolated from a mangrove endophytic fungus Fusarium solani. Fusaricates H-K represent the first cases of fusaric acid butanediol esters and are diastereoisomers. Their structures including absolute configurations were elucidated
从红树林内生真菌 Fusarium solani 中分离出 7 种化合物,包括四种未描述的镰刀菌酸衍生物,即镰刀菌酸 HK,两种未描述的γ-吡喃酮衍生物,名为 Fusolanones AB,以及已知的化合物镰刀菌酸。Fusaricates HK代表了镰刀酸丁二醇酯的第一个例子并且是非对映异构体。基于NMR、MS、化学合成、手性HPLC分析和ECD计算阐明了它们的结构,包括绝对构型。测试了所有未描述的化合物的抗菌活性,呋喃酮 B 对副溶血性弧菌的抗菌活性最好,MIC 值为 6.25 μg/mL。
