Toxicol Appl Pharmacol. 1997 Mar;143(1):56-69.

In the first step, several GST isoenzymes were shown to be active toward EDB and displayed pseudo-first-order kinetics, while the EDB oxidation was catalyzed by CYP2E1, 2A6, and 2B6, which all displayed saturable kinetics.

Out of ten heterologously expressed human P450 isoenzymes (CYP1A1, CYP1A2, CYP2A6, CYP2B6, CYP2E1, CYP2C8, CYP2C9, CYP2C18, CYP3A4 and CYP3A5), only human CYP2A6, CYP2B6 and CYP2E1 metabolized 1,2-DBE, albeit with strongly differing catalytic efficiencies.

To this end, CYP2E1, the main P450 isoenzyme catalyzing the oxidation of 1,2-DBE, was inhibited using disulfiram and diallylsulfide.
