Product Description
AZD-6244 (Selumetinib) is an orally-available, aminobenzimidazole-based, allosteric inhibitor of MEK1 kinase with an IC50 of 14 nM. [1] IC50 concentrations of <40 nM were observed in cellular phosphorylation assays measuring ERK1/2 in various cell lines. In cellular growth assays, AZD-6244 was more potent in cell lines containing activating B-Raf and Ras mutations, with IC50 values ranging from 59 to 473 nM. In HT-29 and Malme-3M cell studies, AZD-6244 was found to induce G1-S cell cycle arrest, inducing apoptosis after a 2-day incubation period. [1] In Colo-205 xenografts, AZD6244 induced increased levels of cleaved caspase-3, indicating apoptosis. [2]In diffuse large B-cell lymphoma (DLBCL) lines, nanomolar concentration of AZD-6244 effectively downregulated MEK/ERK target substrates, including c-Myc, Mcl-1, and Bcl-2. [3]
