（-）-鲁古洛辛

（-）-鲁古洛辛是霉菌毒素的较不常见的光学异构体，（+）-鲁古洛辛于1968年首次从疣粒菌中分离出来。这些异构体似乎不是共同产生的，但都广泛存在于多个真菌属中。（-）-鲁古洛辛已被证明是抗病毒的。（-）鲁古洛辛是研究较少的异构体，其隐含作用是作为霉菌毒素而不是被确立的。关于异构体的相对效力的比较研究很少。

(-)-Rugulosin is the less common optical isomer of the mycotoxin, (+)-rugulosin, which was first isolated from|Myrothecium verrucaria|in 1968. The isomers appear not to be co-produced but both occur widely in several fungal genera. (-)-Rugulosin has been shown to be antiviral. (-)Rugulosin is the less studied of the isomers and its role as a mycotoxin is implied rather than established. There are few comparative studies of the relative potency of the isomers.
