Sporidesmin is a mycotoxin produced by the fungus Pithomyces chartarum. It is a potent hepatotoxin that causes facial eczema in sheep and other livestock. Sporidesmin is a complex molecule with a unique structure that includes a disulfide bridge and a cyclopentane ring. Its synthesis has been studied extensively, revealing that it is produced via a complex biosynthetic pathway involving several enzymatic steps. The molecule's effects on animals are significant, with a primary focus on its hepatotoxic properties. Sporidesmin causes liver damage by disrupting cellular processes and inducing oxidative stress. The importance of studying sporidesmin lies in its impact on livestock health and its potential to cause human health problems. Research on sporidesmin focuses on understanding its biosynthetic pathways, toxicity mechanisms, and potential strategies for prevention and treatment. Sporidesmin is also a model compound for studying mycotoxin research.'

Sporidesmin has previously been shown to generate superoxide radical in vitro. The erythrocytic changes induced by the mycotoxin suggest that it is also capable of generating this radical intracellularly. Sporidesmin toxicity has not previously been reported in this species.

The chronic hepatotoxicity was consistent with exposure to sporidesmin, the toxic metabolite in the spores of the fungus Pithomyces chartarum. The hydroxyl radical may be the proximate agent responsible for the toxic effects.
