pemrametostat succinate

Pemrametostat succinate is an orally active, potent and selective inhibitor of protein arginine methyltransferase 5 (PRMT5) that potently inhibits tumor growth in vitro and in vivo in animal models.

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.
