Inhibition of the CYP Enzymatic System Responsible of Heterocyclic Amines Bioactivation by an Extract.

plant extract has previously demonstrated antiproliferative activity and antimutagenicity against heterocyclic aromatic amines (HAAs) commonly found in cooked meat. The objective of this work was to evaluate the in vitro ability of an ethanolic extract from the medicinal plant extract (ASE), non-heated and heated (180 °C), to inhibit the activity of CYP1A1 and CYP1A2, which are largely responsible for HAAs bioactivation. Ethoxyresorufin and methoxyresorufin -dealkylation assays were performed in rat liver microsomes exposed to ASE (0.
