Seven unusual new ene-yne hydroquinones (-, -), including three rare glycosylated derivatives named pestalotioquinosides A-C (-), were obtained from the marine-derived strain SCSIO41403 of the fungus . Their structures including absolute configurations were elucidated by spectroscopic analysis and induced electronic circular dichroism experiments. In silico molecular docking and surface plasmon resonance studies showed that pestalotioquinoside C () could act as a liver X receptor alpha (LXRα) modulator. Further study showed that LXR target gene was significantly upregulated by , which revealed as a potential LXRα agonist.
从海洋来源真菌 SCSIO41403 中分离得到了 7 种新型的烯炔类对苯二酚(-,-),包括 3 种罕见的糖基化衍生物,命名为 pestalotioquinosides A-C(-)。通过光谱分析和诱导电子圆二色性实验确定了它们的结构,包括绝对构型。基于计算机的分子对接和表面等离子体共振研究表明,pestalotioquinoside C(-)可以作为肝 X 受体α(LXRα)调节剂。进一步的研究表明,-显著上调了 LXR 靶基因 ,表明其为潜在的 LXRα激动剂。
