MEK inhibitor ARRY-438162
An orally active small-molecule inhibitor of MEK1 and MEK2 (MEK1/2) with potential antineoplastic activity. MEK inhibitor ARRY-438162, noncompetitive with ATP, binds to and inhibits the activity of MEK 1 and 2 (MEK1/2). Inhibition of MEK1/2 prevents the activation of MEK1/2 dependent effector proteins and transcription factors, which may result in the inhibition of growth factor-mediated cell signaling and tumor cell proliferation. MEK1/2 (MAP2K1/K2) are dual-specificity threonine/tyrosine kinases that play key roles in the activation of the RAS/RAF/MEK/ERK pathway and are often upregulated in a variety of tumor cell types. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
