12/15-LIPOXYGENASE INHIBITOR ML351 (C15-1305-053)

General description

A cell-permeable, non-toxic naphthyl-oxazole compound that acts as a highly potent, selective, active site directed, mixed type inhibitor of lipoxygenase-12/15 (IC₅₀ = 200 nM for human). The inhibition appears to be non-reductive and reversible in nature. Displays excellent selectivity over 5-LOX (IC₅₀ >50 µM), 12-LOX (IC₅₀ >100 µM), and 15-LOX (IC₅₀ >100 µM) and does not affect the activity of COX-1 and -2 in any significant manner (<10% inhibition at 15 µM). Can cross the blood brain barrier (brain to plasma ratio = 2.8). Offers protection against glutamate-induced oxidative toxicity in mouse neuronal HT22 cells and reduces the size of infarcts in a murine model of ischemic stroke. Displays good aqueous stability over a wide range of pH. Exhibits attractive pharmacokinetic properties (t_1/2 ~ 1 h in both plasma and brain; C_max of 13.8 and 28.8 µM in plasma and brain, respectively; at 30 mg/kg, i.p).
