ML-355

Platelet-type 12-lipoxygenase (12-LO, Cay-10341) catalyzes the formation of 12-HpETE (Cay-44570) from arachidonic acid (Cay-90010). It has been found to be expressed in various tumor cells as well as pancreatic islets and can be activated by inflammatory cytokines. It has also been implicated in the modulation of hemostasis and thrombosis through its role in regulating platelet function. ML-355 is a selective inhibitor of 12-LO with an IC50 value of 0.34 µM. It demonstrates greatly reduced potency for 15-LO-1, 15-LO-2, and 5-LO (IC50s = 9.7, >100, and >100 µM) and no inhibition of COX-1 and -2. In cell-based assays, ML-355 has been shown to decrease calcium mobilization and thrombin receptor PAR4-induced platelet aggregation in patient-derived human platelets and to significantly inhibit arachidonic acid and calcium- ionophore-induced 12-HpETE synthesis in mouse BTC3 cells and human islets.Formal Name: N-2-benzothiazolyl-4-[[(2-hydroxy-3-methoxyphenyl)methyl]amino]-benzenesulfonamide.
