Structures of deepoxytrichothecene metabolites from 3'-hydroxy HT-2 toxin and T-2 tetraol in rats.

ABSTRACT

3'-Hydroxy HT-2 toxin and T-2 tetraol, in vivo metabolites of T-2 toxin, were orally administered to Wistar rats, and four metabolites having a trichothec-9,12-diene nucleus, which were termed deepoxytrichothecenes, were newly found in the excreta. Their structures were confirmed as 3'-hydroxy-deepoxy HT-2, 3'-hydroxy-deepoxy T-2 triol, 15-acetyl-deepoxy T-2 tetraol, and deepoxy T-2 tetraol on the basis of mass and nuclear magnetic resonance spectroscopy. Resolution of T-2 metabolites and corresponding deepoxytrichothecenes by gas-liquid and thin-layer chromatography was also described.
