Mechanism of Action

Targets/IC₅₀/Ki	MEK (Cell-free assay) 12 nM
In vitro	Binimetinib (MEK162) is a recently disclosed potent and selective ATP non-competitive MEK1/2 inhibitor, inhibits pERK in cells with an IC50 of11 nM. This compound (625 nM) inhibits in vitro osteoclast differentiation with IC50 of 39 nM. It (10 μM) inhibits in vitro osteoclast resorption with IC50 of 625 nM. It (2 μM) weakly affects osteoblast differentiation. It (1 μM) combined with MK-2206 (2 μM) completely reverses the resistance of RSK-expressing MCF7 cells.
In vivo	Binimetinib (MEK162) demonstrates dose-related inhibition of ankle swelling in rat adjuvant-induced arthritis (AIA) models, significant at 10 mg/kg and 30 mg/kg when compared to vehicle control. This compound also shows dose-related inhibition of serum IL-6 concentration in rat adjuvant-induced arthritis (AIA) models, with complete inhibition at 10 mg/kg when compared to vehicle control. At 30 mg/kg, it demonstrates dose-related inhibition of relative spleen weights in rat adjuvant-induced arthritis (AIA) models. Additionally, it significantly inhibits bone resorption and inflammation with delayed dosing when compared to vehicle in rat adjuvant-induced arthritis (AIA) models. ARRY-438162 (10 mg/kg, po, bid) reduces disease severity in a dose-related manner in rat collagen-induced arthritis (CIA) and rat adjuvant-induced arthritis (AIA) models. It (po, bid) inhibits increases in ankle diameter by 27% and 50% at 1 mg/kg and 3 mg/kg in the rat collagen-induced arthritis (CIA) model, while ibuprofen has 46% inhibition. ARRY-438162 (10 mg/kg, po, bid) significantly inhibits lesions (inflammation, cartilage damage, pannus formation and bone resorption) by 32% and 60% at 1 mg/kg and 3 mg/kg in the rat collagen-induced arthritis (CIA) model. It inhibits AIA ankle diameter 11% and 34% at 3 mg/kg and 10 mg/kg in rat adjuvant-induced arthritis (AIA) models. When combined with BEZ235, it (6 mg/kg, BID) results in a significant reduction of tumor growth in immunodeficient mice injected with MCF7 cells.
