Biochem/physiol Actions

Orally active, potent and selective MEK1/2 inhibitor with anti-cancer efficacy in cultures and in vivo.
Selumetinib (ARRY-142886; AZD6244) is an orally active, potent and selective MEK1/2 inhibitor (MEK1 IC50 = 14 nM; <20% inhibition of >40 other kinases at 10 µM) that effectively downregulates cellular ERK1/2 phosphorylation levels (IC50 <40 nM post 1h incubation using 5 different cell lines). Selumetinib inhibits MEK1/2-dependent proliferations in cancer cultures (IC50 in nM = 59/Malme-3M, 93/SK-MEL-28, 175/HT-29, 200/SK-MEL-2, 473/MIA PaCa-2) and exhibits anti-tumor efficacy in mice in vivo (10-100 mg/kg p.o. b.i.d.; BxPC3 & HT-29 xenograft models).
