Background

VX-11e is a potent and selective inhibitor of ERK [1].
ERK is extracellular signal-regulated kinases. The Ras/Raf/MEK/ERK signal transduction is an oncogenic pathway related to a variety of human cancers [1].

Protocol

Kinase experiment [1]:

ERK inhibition assay

Compounds were assayed for the inhibition of ERK2 by a spectophotometric coupled-enzyme assay. In this assay, a fixed concentration of activated ERK2 (10 nM) was incubated with various concentrations of the compounds in DMSO (2.5%) for 10 mins at 30 ℃ in 0.1 M HEPES buffer, pH = 7.5, containing 10 mM MgCl2, 2.5 mM phosphoenolpyruvate, 200 μM NADH, 150 μg/mL pyruvate kinase, 50 μg/mL lactate dehydrogenase and 200 μM erktide peptide. The reaction was initiated by the addition of 65 μM ATP. The rate of decrease of absorbance at 340 nM was monitored. The IC50 was evaluated from the data as a function of inhibitor concentration.

Cell experiment [1]:

Cell lines

HT29 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℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reaction Conditions

≤ 10 μM; 48 hrs

Applications

In HT29 cells, VX-11e potently inhibited cell proliferation with an IC50 value of 48 nM.

Animal experiment [2]:

Animal models

NSG mice bearing human melanoma RPDX tumors

Dosage form

50 mg/kg; p.o.; b.i.d.

Applications

In NSG mice bearing human melanoma RPDX tumors, VX-11e (50 mg/kg, p.o.) potently inhibited pRSK and tumor growth. VX-11e, combined with BKM120, resulted in significantly improved tumor growth inhibition.

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.
