NCIt definition : An orally active, small molecule with potential antineoplastic activity. Selumetinib
is an ATP-independent inhibitor of mitogen-activated protein kinase kinase (MEK or
MAPK/ERK kinase) 1 and 2. MEK 1 and 2 are dual specificity kinases that are essential
mediators in the activation of the RAS/RAF/MEK/ERK pathway, are often upregulated
in various cancer cells, and are drivers of diverse cellular responses, including
proliferation. Inhibition of both MEK1 and 2 by selumetinib prevents the activation
of MEK1/2 dependent effector proteins and transcription factors, thereby leading to
an inhibition of cellular proliferation in various cancers.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of several types of cancer.
AZD6244 blocks proteins needed for cell growth and may kill cancer cells. It is a
type of protein kinase inhibitor.;
