Background
Trametinib, also known as GSK1120212, is a potent and selective inhibitor of MEK with an IC of 0.7 nM for u-MEK1 and 14.9 nM for pp-MEK1 (1). When compared to several tyrosine kinase inhibitors (TKIs) and MEK inhibitors (MEKIs) in endothelial cells, Trametinib displays the highest level of antiangiogenic activity and is the most effective ERK1/2 inhibitor (IC = 1.3 nM) (2). Trametinib has also been shown to be the most effective at reducing proliferation in low-grade serous ovarian cancers (LGSCs) when compared to other MEKIs (3).
