Along with the tremorgenic mycotoxins, penitrems A (3), B (4), D (6), E (7), and F (8), the minor metabolites 1 and 2 were isolated from the mycelia of Penicillium crustosum THOM, which was found contaminating bread intended for school lunches in Tokyo city. The structures of 1 and 2 were determined on the basis of spectroscopic and chemical investigations. these compounds (1 and 2) might be biosynthetic precursors of penitrems.
除了颤动性霉菌毒素外,从东京市学校午餐用面包中发现污染的Penicillium crustosum THOM菌丝体中分离出了次要代谢产物1和2。根据光谱和化学研究确定了1和2的结构。这些化合物(1和2)可能是penitrems的生物合成前体。
