Scientific Background: Verrucarin A is a macrocyclic trichothecene mycotoxin from Myrothecium sp. It is being investigated as it modulates amyloid-beta production in Alzheimer's patients neurons (1). It is a potent and selective inhibitor of the steroid receptor coactivator-3 and selectively down-regulates its expression (2). It is cytotoxic to multiple types of cancer cells at low nM concentrations (IC50=4.9 nM for HepG2 cells) but not toward normal liver cells (2,3). It enhances TNFα-induced (4) and TRAIL-induced apoptosis (5). It reduces phosphorylation of IREα and inhibits tunicamycin-induced ER stress in FaO rat liver cells (6).
