Sclerotiorin is an unusual azaphilone pigment first isolated from Penicillium sclerotiorum by MacCurtin and Reilly, University of Cork, Ireland in 1940. Sclerotiorin has broad biological activity and is a potent aldose reductase (IC50 0.4 µM) and lipoxygenase (IC50 4.2 µM) inhibitor and radical scavenger. Sclerotiorin induces apoptosis in colon cancer (HCT-116) cells through the activation of BAX, and down-regulation of BCL-2. Sclerotiorin has antifungal and antibacterial activity.
