ETP 45835 dihydrochloride is a Mnk2 and Mnk1 inhibitor (IC50 values are 575 and 646 nM respectively). Exhibits selectivity against a panel of 24 protein Ki nases, including those upstream of Mnk1 2.
Tomivosertib, also known as eFT508 is a MNK1 2 inhibitor. Tomivosertib binds to and inhibits the activity of MNK1 and 2. This prevents MNK1 2-mediated signaling, and inhibits the phosphorylation of certain regulatory proteins, including eukaryotic translation initiation factor 4E (eIF4E), that regulate the translation of messenger RNAs (mRNAs) involved in tumor cell proliferation, angiogenesis, survival and immune signaling.
