Common Name | Thelephoric acid |

Description | Thelephoric acid, also known as thelephate, belongs to the class of organic compounds known as benzofurans. These are organic compounds containing a benzene ring fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Thelephoric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). It is derived from atromentin, and its precusor can be from cyclovariegatin. Outside of the human body, thelephoric acid has been detected, but not quantified in, mushrooms. This could make thelephoric acid a potential biomarker for the consumption of these foods. Fragmentation patterns have suggested that polymers of thelephoric acid exists. Chemicals that inhibit prolyl endopeptidase have attracted research interest due to their potential therapeutic effects. 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. |
