The new polycyclic polyprenylated acylphloroglucinols, hyperforcinols A-J (-), were isolated from the fruits of , together with 30 biogenetic congeners of known structures. The structures of hyperforcinols A-J were determined by HRESIMS and 1D/2D NMR spectroscopic analysis, and their absolute configurations were determined by a combination of the electronic circular dichroism (ECD) exciton chirality method, ECD calculations, and X-ray diffraction analysis. A selection of 25 isolates, possessing seven types of carbon skeletons, were assessed for their in vitro effects against nonalcoholic steatohepatitis (NASH) using a free fatty acid-induced L02 cell model. Compounds and significantly decreased intracellular lipid accumulation. QRT-PCR analyses revealed that compounds and regulate the expression of lipid metabolism-related genes, including , , , and .
新型多环多聚异戊烯基酰基间苯三酚类化合物,hyperforcinols A-J(-),从 的果实中分离得到,同时还分离得到了 30 种已知结构的生物合成同系物。通过高分辨质谱(HRESIMS)和 1D/2D NMR 波谱分析确定了 hyperforcinols A-J 的结构,通过电子圆二色性(ECD)外消旋手性法、ECD 计算和 X 射线衍射分析相结合的方法确定了它们的绝对构型。对具有七种碳骨架的 25 种分离物进行了体外非酒精性脂肪性肝炎(NASH)的评估,采用游离脂肪酸诱导的 L02 细胞模型进行评估。化合物 和 显著降低了细胞内脂质积累。QRT-PCR 分析表明,化合物 和 调节脂质代谢相关基因的表达,包括 、 、 、和 。
