(9.99mM)
Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
* <1 mg/ml means slightly soluble or insoluble. * Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations. * Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity
Description
VX-11e (VTX-11e, Vertex-11e) is a potent, selective, and orally bioavailable ERK inhibitor with IC50 of 17 nM (ERK1) and 15 nM (ERK2), over 200-fold selective over other kinases tested.
Targets
ERK2 (Cell-free assay)
ERK1
<2 nM(Ki)
17 nM
In vitro
In HT29 cells, VX-11e potently inhibits cell proliferation with IC50 of 48 nM.
In Vivo
In both rats and mice, VX-11e shows good oral bioavailability. In NSG mice bearing human melanoma RPDX tumors, this compound (50 mg/kg, p.o.) results in robust inhibition of pRSK, and inhibits tumor growth. When used in combination with BKM120, this chemical results in significantly improved tumor growth inhibition.
Compounds are assayed for the inhibition of ERK2 by a spectrophotometric coupled-enzyme assay. In this assay, a fixed concentration of activated ERK2 (10 nM) is incubated with various concentrations of the compounds in DMSO (2.5%) for 10 min. at 30 °C 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 is initiated by the addition of 65 μM ATP. The rate of decrease of absorbance at 340 nM is monitored. The IC50 is evaluated from the data as a function of inhibitor concentration.
Cell proliferation is measured by 3H-thymidine incorporation. The cells are plated at a concentration of 10,000 cells/well in a 96-well plate using growth media, RPMI 1640 containing 10% FBS. Serially diluted compounds are added. The cells and this compound are incubated for 48 hours at 37°C incubator. After 48 hours, 0.4 μCi of 3H-thymidine is added to each wells for 8 hours and returned to the 37°C incubator. The cells are harvested using a Tomtec 96-well cell harvester and the CPM is determined using the Wallac 1205 BETAPLATE liquid scintillation counter. The IC50 is the 50% inhibition of contr
