Pentahydroxyscirpene, a novel trichothecene-type compound, was isolated from Fusarium-inoculated rice. The structure of pentahydroxyscirpene was elucidated by 1D and 2D NMR spectroscopy and X-ray single-crystal diffraction. The conformation in solution was determined by NOESY experiments supported by quantum chemical calculations. In vitro toxicity tests showed that pentahydroxyscirpene inhibits protein
Pentahydroxyscirpene 是一种新型的单端孢霉烯类化合物,是从接种镰刀菌的水稻中分离出来的。通过一维和二维核磁共振光谱和 X 射线单晶衍射阐明了五羟基芘的结构。溶液中的构象由量子化学计算支持的 NOESY 实验确定。体外毒性试验表明,五羟基鼠尾草烯与其他单端孢霉烯一样抑制蛋白质合成。
