(Z)-4EGI-1 is the Z-isomer of 4EGI-1 and is an inhibitor of eIF4E/eIF4G interaction and of translation initiation. (Z)-4EGI-1 effectively binds to eIF4E with an IC50 of 43.5 μM and a Kd value of 8.74 μM. (Z)-4EGI-1 has anticancer activity[1][2].
(Z)-4EGI-1 (15-30 µM; 6 hours; CRL-2813 melanoma cells) treatment markedly reduces the expressions of the regulatory proteins: cyclin D1, cyclin E, and Survivin, while the expressions of housekeeping proteins such as β-Actin and α-Tubulin are not affected[1].
(Z)-4EGI-1 inhibits cancer cells proliferation with IC50 values of 15.3 μM and 11.6 μM for CRL-2351 breast cells and CRL-2813 melanoma cells, respectively[2].
