Background

Trametinib (also known as GSK1120212 or JTP 74057), originally identified as a p15 inductive compound, is a novel and potent allosteric inhibitor of MEK kinase, which exhibits ATP non-competitive inhibition against MEK1 and MEK2 kinase. It has demonstrated broad antitumor activities in a variety of tumor xgenograft models, including HT-29 and COLO205 colorectal tumor cell lines. Trametinib induces expression of p15 and p27, reduces cyclin D1 levels, and causes dephosphorylation of RB protein and G1-phase arrest with a reduction of TS expression in HT-29 cells. It also effectively inhibits p-ERK 1/2 resulting in cell growth inhibition in tumor cell lines harboring B-RAF mutant.

Protocol

Cell experiment: [1]
Cell lines	HT-29 cells
Preparation method	The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.
Reaction Conditions	100 nM, 72 hours
Applications	Trametinib showed a subnanomolar IC50 value for 72 h in a Cell Counting Kit-8 assay of human colon cancer HT-29 cells. The treatment with trametinib for 24 h dose-dependently increased the G1 phase with a decrease in the S phase, and 72 h treatment induced apoptosis in a dose-dependent manner together with G1 arrest.
Animal experiment: [2]
Animal models	Male ICR mice
Dosage form	Oral administration, 3 mg/kg, daily
Applications	GSK1120212 was effective at blocking phosphorylation of ERK over 24 h and 7 d. To test whether the inhibitor blocked adaptive growth, mice were treated with GSK1120212 and/or the trypsin inhibitor camostat mesylate S (TI) for 7 d. TI-induced pancreatic growth was blocked by GSK1120212 as measured by pancreatic mass, protein, DNA, and RNA content. These results show that GSK1120212 like PD0325901 blocks pancreatic adaptive growth induced by TI.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
