| Common Name | Asperxanthone |
|---|
| Description | Asperxanthone, also known as TMC 256C2, belongs to the class of organic compounds known as naphthopyranones. Naphthopyranones are compounds containing a naphthopyran skeleton where a ring carbon bears a carboxylic acid group. Naphthtopyran is made up of the pyran ring fused to a naphthalene ring system. Asperxanthone is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Asperxanthone has been detected, but not quantified in, fruits and nuts. Asperxanthone is found in Aspergillus niger. Asperxanthone was first documented in 1984 (PMID: 6548104). This could make asperxanthone a potential biomarker for the consumption of these foods (PMID: 18205129) (PMID: 25809933) (PMID: 26669099) (PMID: 21652743) (PMID: 18823067) (PMID: 19160525). |
