Description: GDC-0623, also known as G-868, is an orally active, selective MEK inhibitor with potential antineoplastic activity. MEK inhibitor GDC-0623 specifically inhibits mitogen-activated protein kinase kinase (MEK or MAP/ERK kinase), resulting in inhibition of growth factor-mediated cell signaling and tumor cell proliferation. MEK is a key component of the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth; constitutive activation of this pathway has been implicated in many cancers. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Additional Information

GDC-0623, a selective inhibitor of MEK, also known as mitogen activated protein kinase kinase (MAPKK), is a key component of the RAS/RAF/MEK/ERK pathway, which is frequently activated in human tumors. Inappropriate activation of the MEK/ERK pathway promotes cell growth in the absence of exogenous growth factors.
