Two polyketides were isolated from the mangrove endophytic fungus, Penicillium sp. sk14JW2P, and one derivative with a modified structure. The structures were elucidated by spectroscopic analyses, the structure of the compound 1 was further confirmed by single‐crystal X‐ray diffraction, and its absolute configuration was determined. Compound 1 and 2 showed acetylcholinesterase (AchE) inhibitory activities
从红树林内生真菌Penicillium sp。中分离出两个聚酮化合物。sk14JW2P,以及一种结构经过修改的衍生物。通过光谱分析阐明了结构,通过单晶X射线衍射进一步确定了化合物1的结构,并确定了其绝对构型。化合物1和2显示出乙酰胆碱酯酶抑制活性用IC 50的12±0.3和79±2 n个值中号分别。
