Polyozellin

Polyozellin is a chemical which occurs in the mushroom Polyozellus multiplex. It inhibits prolyl endopeptidase, an enzyme that has a role in processing proteins (specifically, amyloid precursor protein) in Alzheimer's disease. Chemicals that inhibit prolyl endopeptidase have attracted research interest due to their potential therapeutic effects.[1] Structurally related dibenzofuranyl derivatives of polyozellin are known as kynapcins.[2]
