Tomivosertib hydrochloride
Based on 15 publication(s) in Google Scholar
Tomivosertib hydrochlorideis a potent, highly selective, and orally active MNK1 and MNK2 inhibitor, with IC50s of 1-2 nM against both isoforms. Tomivosertib hydrochloride treatment leads to a dose-dependent reduction in eIF4E phosphorylation at serine 209 (IC50=2-16 nM) in tumor cell lines. Tomivosertib hydrochloride also dramatically downregulates PD-L1 protein abundance.
