ML 351

Description

Lipoxygenases (LOs) are non-heme iron-containing dioxygenases that catalyze the oxidation of polyunsaturated fatty acids to generate unsaturated fatty acid hydroperoxides. The immediate products of 15-LO fatty acid oxidation act as mediators in inflammation, thrombosis, and cancer. ML351 is an inhibitor of human reticulocyte 15-LO-1 (IC₅₀ = 200 nM) with >250-fold selectivity over the related enzymes 5-LO, platelet 12-LO, 15-LO-2, ovine COX-1, and human COX-2. ML351 was shown to be protective against oxidative glutamate toxicity in mouse neuronal HT-22 cells and significantly reduced infarct size in an in vivo mouse model for ischemic stroke.

Uses

ML351 is a selective 12/15 LOX inhibitor (IC50 = 200 nM). Exhibits >250-fold selectivity over related isozymes, 5-LOX, platelet 12-LOX, 15-LOX-2, ovine COX-1, and human COX-2. Protects against oxidative glutamate toxicity in mouse neuronal cells (HT-22) and reduces infarct size in a mouse ischemic stroke model.

Biochem/physiol Actions

ML351 is a cell penetrant, selective and highly potent human lipoxygenase-12/15 (15-Lipoxygenase-1, 12/15-LOX) inhibitor that exhibits protective effects against oxidative glutamate toxicity in mouse neuronal HT22 cells. ML351 reduces infarct size in a mouse model of ischemic stroke.
