NCIt definition : A dimethyl sulfoxide (DMSO) solvated form of trametinib, an orally bioavailable inhibitor
of mitogen-activated protein kinase kinase (MAP2K; MAPK/ERK kinase; MEK) 1 and 2,
with potential antineoplastic activity. Upon oral administration, trametinib specifically
binds to and inhibits MEK 1 and 2, resulting in an inhibition of growth factor-mediated
cell signaling and cellular proliferation in various cancers. MEK 1 and 2, dual specificity
serine/threonine and tyrosine kinases often upregulated in various cancer cell types,
play a key role in the activation of the RAS/RAF/MEK/ERK signaling pathway that regulates
cell growth.;
