Alternariol

Alternariol is an orally ingested mycotoxin produced by Alternaria, capable of inhibiting the activity of topoisomerase I and II (topoisomerase I, topoisomerase II). Alternariol has weak estrogenic (Estrogen Receptor/ERR) and androgen/antiandrogen (Androgen Receptor) effects. Alternariol can induce apoptosis, trigger cell cycle arrest, suppress innate immune responses, and exhibit anti-tumor activity. Alternariol has genotoxic, mutagenic, and endocrine-disrupting effects[1][2][3][4][5].
