What is Nigerone?

Plain description, key identifiers and synonyms

Nigerone is a biaryl resulting from the formal oxidative dimerisation of two molecules of 5-hydroxy-6,8-dimethoxy-2-methyl-4H-benzo[g]chromen-4-one to form a single bond linking position 10 of each moiety (the 10Ra enantiomer). It has a role as a mycotoxin, an antifungal agent and an Aspergillus metabolite. It is a member of phenols, a biaryl and a benzochromenone.

Nigerone is a nigerone is produced by Aspergillus niger. Mycotoxin.
