Background:

VX-11e is a potent, selective, and orally bioavailable inhibitor of ERK with Ki< 2 nM.

VX-11e?is active in the HT29 cell proliferation assay (IC50=48 nM)[1].

VX-11e is orally bioavailable in both rat and mice[1]. VX-11e (50 mg/kg, p.o.) results in robust inhibition of pRSK, and inhibits tumor growth in NSG mice bearing human melanoma RPDX tumors. VX-11e with BKM120 significantly improves tumor growth inhibition[2].
