eukaryotic translation initiation factor 3

Eukaryotic initiation factors (eIF) are proteins involved in the initiation phase of eukaryotic translation. Eukaryotic translation initiation factor 3 binds to the ribosome subunit-mRNA complex. It has been implicated in preventing the large ribosomal subunit from binding the small subunit before it is ready to commence elongation.

ZMF-24 is an anti-triple-negative breast cancer (TNBC) agent that exhibits IC50 values of 0.22 μM and 0.44 μM against BT-549 and MDA-MB-231 TNBC cell proliferation, respectively. It targets the eukaryotic translation initiation factor 3 subunit D (EIF3D), disrupting TNBC's energy supply by inhibiting glycolysis. Additionally, ZMF-24 induces TNBC cell apoptosis (apoptosis) by stimulating sustained endoplasmic reticulum stress.

eIF4A-IN-3 (Compound 71E) is an inhibitor of the eukaryotic translation initiation factor 4A (eIF4A). This compound can be utilized as a cytotoxic payload for antibody-drug conjugates (ADCs).

eIF4E-IN-3 is a small-molecule inhibitor targeting eIF4E that disrupts cap-dependent mRNA translation initiation. By inhibiting eIF4E function, eIF4E-IN-3 modulates translation of specific proteins and has potential applications in mechanistic studies of eIF4E-dependent diseases such as cancer.
