Product Information:

CGP-57380 is a selective inhibitor of MAP kinase-interacting kinase 1 (MNK1) in vitro (IC50 = 2.2 μM). MNK1 overexpression was confirmed in both primary GBMs and glioma cell lines. Inhibition of MNK1 activity in GBM cells by the small molecule CGP57380 suppressed eIF4E phosphorylation, proliferation, and colony formation whereas concomitant treatment with CGP57380 and the mTOR inhibitor rapamycin accentuated growth inhibition and cell-cycle arrest.

In Vitro:

CGP57380 inhibits phosphorylation of eIF4E in cellular assays with IC50 of about 3 μM. CGP57380 causes dephosphorylation of eIF4E, and induces a further increase in the cap-dependent reporter in 293 cells. CGP57380 results in dose-dependent decreases in Ang II-stimulated phosphorylation of eIF4E, protein synthesis, and VSMC hypertrophy. CGP57380 sensitizes wild-type cells for serum-withdrawal induced apoptosis in mouse embryo fibroblasts (MEFs). CGP57380 prevents the serial replating function of BC progenitors.


In Vivo:

CGP57380 (40 mg/kg/d i.p.) potently extinguishes the ability of BC CML cells to serially transplant-immunodeficient mice and function as LSCs.
