Uterotropic activity of cis and trans isomers of zearalenone and zearalenol. 1978

C J Mirocha, and S V Pathre, and J Behrens, and B Schauerhamer

The cis and trans isomers of zearalenone [2,4-dihyroxy-6-(10-hydroxy-6-oxo-1-undecenyl)-benzoic acid mu-lactone] and zearalenol [2,4-dihydroxy-6-(6,10-dihydroxy-1-undecenyl)-benzoic acid mu-lactone] were tested for uterotropic activity in the white rat. The metabolites were administered through the oral route (per os) and by topical application to the freshly shaven skin on the back. cis-Zearalenone was significantly more active than trans when fed orally to the rats in the diet or when applied topically by skin application. However, the cis isomer of zearalenol was not significantly different than its trans isomer. trans-Zearalenone was less active than trans-zearalenol.

One of a group of compounds known under the general designation of resorcylic acid lactones.
