Cat.No. 3975 - Zearalenone | C18H22O5 | CAS No. 17924-92-4
Description: Estrogen receptor ligand; mycotoxin
Chemical Name: (3S,11E)-3,4,5,6,9,10-Hexahydro-14,16-dihydroxy-3-methyl-1H-2-benzoxacyclotetradecin-1,7(8H)-dione

Biological Activity

Mycotoxin produced by several species of Fusarium fungi. Binds to the estrogen receptor (ER) (IC50 values are 166 and 240 nM for ERβ and ERα respectively) and stimulates the transcriptional activity of both subtypes at concentrations between 1 - 10 nM. Also stimulates growth of T47D breast cancer cells.

Pathways for Zearalenone


Estrogen Signaling Pathway

Estrogen is a steroid hormone that is responsible for the regulation of growth, differentiation and function of the reproductive system. Estrogen signaling is often dysregulated in breast cancer and osteoporosis.
