Description: | eFT508 is a potent, highly selective, and orally bioavailable MNK1 and MNK2 inhibitor, with IC50s of 1-2 nM against both isoforms. |
Target: | MNK1:1-2 nM (IC50) MNK2:1-2 nM (IC50) |
In Vivo: | eFT508 shows significant anti-tumor activity in the TMD8 and HBL-1 ABC-DLBCL models, both of which harbor activating MyD88 mutations. Besides, eFT508 combines effectively with components of R-CHOP and with novel targeted agents, including ibrutinib and venetoclax, in human lymphoma models[1]. |
In Vitro: | eFT508 reduces eIF4E phosphorylation dose-dependently at serine 209 (IC50=2-16 nM) in tumor cell lines. In a panel of appr 50 hematological cancers, eFT508 shows anti-proliferative activity against multiple DLBCL cell lines. Sensitivity to eFT508 in TMD8, OCI-Ly3 and HBL1 DLBCL cell lines is associated with dose-dependent decreases in production of pro-inflammatory cytokines including TNFα, IL-6, IL-10 and CXCL10. Further evaluation eFT508 mechanism of action demonstrates that decreased TNFα production correlates with a 2-fold decrease in TNFα mRNA half-life[1]. |
