NCIt definition : An orally available inhibitor of extracellular signal-regulated kinase (ERK), with
potential antineoplastic activity. Upon oral administration, ravoxertinib inhibits
both ERK phosphorylation and activation of ERK-mediated signal transduction pathways.
This prevents ERK-dependent tumor cell proliferation and survival. The mitogen-activated
protein kinase (MAPK)/ERK pathway is upregulated in a variety of tumor cell types
and plays a key role in tumor cell proliferation, differentiation and survival.;
