Zearalanone (ZAN) is an estrogen receptor agonist and also an androgen receptor antagonist [1].
Zearalenone (ZEN), a β-resorcyclic acid lactone (RAL), is a non-steroidal estrogenic mycotoxin biosynthesized by several Fusarium species. Zearalenone (ZEN) is the well-known mycotoxin present in numerous agricultural products [1][2][3][4]. In the human endometrial Ishikawa cell line, zearalenone (ZEN) exhibited strong oestrogenicity [4].When incubated Fusarium semitectum on sorghum, the ratio of ZAN to ZEN remained constant after 5 days, suggesting that ZAN might not be suitable for use as an internal standard [5].
Zearalanone, a major phase I metabolite of zearalenone (ZEN), is an estrogen receptor agonist and also an androgen receptor antagonist. In MCF-7 cells, Zearalanone strongly induced cell proliferation with EC50 value of 1.21 nM and showed significant estrogenic activity. Zearalanone behaved as full hERα agonist. In PALM cells, Zearalanone acted as a hAR antagonist that strongly inhibited the luciferase activity induced by 0.3 nM of R1881, the synthetic androgen [1].
