(Z)-4EGI-1 is the Z-isomer of 4EGI-1, functioning as an inhibitor of eIF4E/eIF4G interaction and translation initiation. It binds effectively to eIF4E with an IC50 of 43.5 μM and a Kd value of 8.74 μM, and exhibits anticancer activity. In vitro studies with melanoma cells showed that treatment with (Z)-4EGI-1 significantly reduced the expression of regulatory proteins such as cyclin D1, cyclin E, and Survivin, while housekeeping proteins remained unaffected. It also inhibits the proliferation of cancer cells.
