Thelephoric acid is a terphenylquinone pigment that is found in several fungi, such as Omphalotus subilludens[1] and Polyozellus multiplex.[2] Thelephoric acid has been shown to inhibit 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.[3][4]
