MilliporeSigma™ Calbiochem™ 5-Lipoxygenase Inhibitor, MK591

Description

MK591; MK0591; 5-LOX inhibitor, 5- Lipoxygenase inhibitor, FLAP

A cell permeable, bioavailable, 2-indolealkanoic acid derived compound that acts as a highly potent and selective inhibitor of leukotriene biosynthesis (IC₅₀ = 3.1nM in intact human polymorphonuclear leukocytes). Shown to inhibit 5-lipoxygenase (5-LOX) activity in LNCaP prostate cancer cells by high-affinity binding to 5-lipoxygenase activating protein (FLAP; IC₅₀ = 1.6nM in a FLAP binding assay). Induces apoptosis in LNCaP cells without blocking PI 3 kinase-Akt or ERK activities. Also shown to induce rapid phosphorylation of c-Jun N-terminal Kinase (JNK) and indirectly block PKCε activity. Suppresses the deposition of Ab1-40 and Ab1-42 peptides in Tg2576 mice (∽40mg/kg/day in diet) with concomitant reduction in the levels of presenilin 1, nicastrin, APH-1 and Pen-2, but without affecting notch signaling. Exhibits desirable pharmacokinetic properties with tmax of 3.3 h and t1/2 = ∽12 h.

Please note that the molecular weight for this compound is batch-specific due to variable water content.
