Cyclopiazonic acid (CPA) is a toxic fungal secondary metabolite. Chemically, CPA is related to ergoline alkaloids. CPA was originally isolated from Penicillium cyclopium and subsequently from other fungi including Penicillium griseofulvum, Penicillium camemberti, Penicillium commune, Aspergillus flavus, and Aspergillus versicolor. CPA only appears to be toxic in high concentrations. Biologically, CPA is a specific inhibitor of SERCA ATPase in intracellular Ca2+ storage sites.
