Biological Activity

[Description]:

CI-1040 (PD184352) is an orally active, highly specific, small-molecule inhibitor of MEK with an IC50 of 17 nM for MEK1.

[Target]

MEK1:17 nM (IC50)

[In Vitro]

CI-1040 directly inhibits MEK1 with an IC50 of 17 nM. It has also been shown to have little activity against a panel of related kinases with IC50 values more than 2.5 orders of magnitude higher. Treatment of whole cells with CI-1040 completely inhibits the mitogen-stimulated phosphorylation of ERK. CI-1040 at a concentration of 1 μM is found to inhibit phosphorylation of ERK1 and ERK2 by 99% and 92%, respectively in MDA-MB-231 breast cancer cells[1]. CI-1040 induces apoptosis and inhibits proliferation in U-937 cells in a dose and time-dependent manner. CI-1040 induces a significant increase in PUMA mRNA and protein levels[2].

[In Vivo]

The systemic administration of the MEK inhibitor CI-1040 reduces adenoma formation to a third and significantly restores lung structure. The proliferation rate of lung cells of mice treated with CL-1040 is decreased without any obvious effects on differentiation of pneumocytes[3].

[Cell Assay]

The MEK inhibitor CI-1040 is dissolved in DMSO as 10 mM stock solutions and used in cell culture at final concentration 50 mg/mL. U-937 cells are pretreated for 24 hrs with 5 and 20 uM CI- 1040, then transfected with wt-p53 siRNA or PUMA siRNA for 48 hrs. Then 20 mL of MTT solution are added to each well and incubated further for 2 hours. Upon termination, the supernatant is aspirated and the MTT formazan formed by metabolically viable cells is dissolved in 100 mL of isopropanol. The plates are mixed for 30 minutes on a gyratory shaker, and absorbance is measured at 595 nm using a plate reader[2].

[Animal admin]

Mice: The lung cancer mouse model is generated by targeting constitutively active C-Raf kinase to the lung. BAY 43-9006 or CI-1040 is daily intraperitoneal injected at a dose of 100 mg/kg from 4 months of age over a period of 21 days. Lungs were isolated and analyzed at the end of the treatment period[3].
