Myeloperoxidase Inhibitor-I-CAS 5351-17-7-Calbiochem

产品说明

一般描述

A benzoic acid hydrazide analog that acts as a potent, irreversible, and specific inhibitor of the peroxidation activity of myeloperoxidase (MPO; IC₅₀ = 300 nM). Does not inhibit catalase or glutathione peroxidase activities. Does not affect the production of superoxide by neutrophils. Shown to inhibit H₂O₂-induced apoptosis in HL-60, human leukemia cells.
A benzoic acid hydrazide analog that acts as a potent, specific, and irreversible inhibitor of myeloperoxidase. ABAH is a mechanism-based inhibitor that is oxidized to radical intermediates that, in turn, promote the irreversible inactivation of myeloperoxidase. Reported to inhibit hypochlorous acid (HOCl) production by purified myeloperoxidase (IC₅₀ = 300 nM). Has also been shown to inhibit HOCl production up to 90% in zymosan and phorbol myristate acetate stimulated neutrophils (IC₅₀ = 16 µM and 2.2 µM, respectively). Does not affect superoxide radical production or degranulation of neutrophils and does not inhibit catalase or glutathione peroxidase. Shown to inhibit myeloperoxidase-mediated apoptosis in >90% of ras-expressing fibroblasts and glutathione-depleted, src-transformed cells. Also shown to inhibit apoptosis in H₂O₂-treated HL-60 promyelocytic leukemia cells.
