Selumetinib (AZD6244) (C09-1043-753)

InformationIn vitroAZD6244 is not competitive with ATP and inactivates the ERK1/2 phosphorylation with IC50 concentrations below 40 nM. AZD6244 also inhibits the growth of primary HCC cells through inhibition of ERK1/2 and p90RSK phosphorylation, accompanied with elevation of the cleavage of caspase-3 and caspase-7, and cleaved poly(ADP)ribose polymerase. AZD6244 has little effects on the p38, c-Jun-NH2-kinase, phosphatidylinositol 3-kinase, and MEK5/ERK5 pathways. AZD6244 is sensitive to Raf mutations in breast cancer cell lines and Ras mutations in NSCLC cell lines.In vivoAZD6244 significantly inhibits phosphorylation of ERK1/2 in 2-1318, 5-1318, 26-1004 and 4-1318 xenografts and induces apoptosis in primary 2-1318 cells by activating the caspase pathway. AZD6244 could inhibit the tumor growth in HT-29 xenograft, which is a colorectal tumor model carrying a B-Raf mutation, at a dose of 100 mg/kg and the tumor growth inhibition of AZD6244 is better than it of Gemcitabine. Otherwise AZD6244 could inhibit HCC xenografts tumor growth, which associated with increased apoptosis and down-regulation of cell cycle regulators, including cyclin D1, Cdc-2, CDK2 and 4, cyclin B1, and c-Myc.Cell Datacell lines：Concentrations：~ 10 μMIncubation Time：24 or 48 hoursPowder Purity:≥99%.
