Overview

9,10-dihidro derivate of aflatoxin G1. A potent hepatotoxic and hepatocarcinogenic mycotoxin

Product description

Aflatoxin G2 is a fungal secondary toxic metabolite synthesized by Aspergillus parasiticus, Aspergillus flavus, and Aspergillus nomius, species that are found in tropical and subtropical regions of the world. Aflatoxin Gs (AFGs) are derivatives of difuranocoumarin and contain a bifuran group linked to a coumarin nucleus and a lactone ring.
