Biological Activity

[Description]:

MK-886 (L 663536) sodium salt is a potent, cell-permeable and orally active FLAP (IC50 of 30 nM) and leukotriene biosynthesis (IC50s of 3 nM and 1.1 μM in intact leukocytes and human whole blood, respectively) inhibitor. MK-886 sodium salt is also a non-competitive PPARα antagonist and can induce apoptosis[1][2][3].

[Target]

IC50: 30 nM (FLAP)[3] IC50: 3 nM (Leukotriene biosynthesis in intact leukocytes) and 1.1 μM (Leukotriene biosynthesis in human whole blood)[2] PPARα[1]


[In Vitro]

MK-886 sodium salt (0.5-2 μM; 15?hours; primary keratinocytes) treatment reduces keratin-1 expression in a culture of mouse primary keratinocytes[1]. ?Using a transient transfection system in monkey kidney fibroblast CV-1 cells, mouse keratinocyte 308 cells and human lung adenocarcinoma A549 cells, 10 μM MK-886 sodium salt is able to inhibit Wy-14643 activation of PPARα by ~80%. MK-886 sodium salt also decreases PPARα activation by fatty acids in the stable transfection system[1]. ?Although Jurkat cells express all PPAR isoforms, various PPARα and PPARγ agonists are unable to prevent MK-886 sodium salt-induced apoptosis[1].

[In Vivo]

MK-886 sodium salt (L 663536; 5 mg/kg; oral administration; male Sprague-Dawley rats) treatment potently inhibits the antigen-induced dyspnea in inbred rats pretreated with methysergide[2]. ?MK-886 sodium salt (L 663536) inhibits leukotriene biosynthesis in vivo in a rat pleurisy model (ED50, 0.2 mg/kg p.o.), an inflamed rat paw model (ED50, 0.8 mg/kg), a model of leukotriene excretion in rat bile following antigen provocation[2].
