Mechanism of inactivation of myeloperoxidase by 4-aminobenzoic acid hydrazide [PDF]
Biochemical Journal, 1997 Hypochlorous acid is the most powerful oxidant generated by neutrophils and is likely to contribute to the damage mediated by these inflammatory cells. The haem enzyme myeloperoxidase catalyses its production from hydrogen peroxide and chloride. 4-Aminobenzoic acid hydrazide (ABAH) is a potent inhibitor of hypochlorous acid production.
