The eukaryotic initiation factor 4E (eIF4E) is an emerging anticancer drug target for specific anticancer therapy as a promising approach to overcome drug resistance and promote chemotherapy antitumor efficacy. A series of bromophenol-thiazotylhydrazone hybrids were designed, synthesized and evaluated for their antitumor activities. Among of them, the most potent compound 3e (EGPI-1) could inhibit the eIF4E/eIF4G interaction. Further mechanism study demonstrated EGPI-1 played an antitumor role in multiple modes of action including regulating the activity of elF4E by inhibiting the phosphorylation of eIF4E and 4EBPI, disrupting mitochondrial function through the mTOR/4EBP1 signaling pathway, and inducing autophagy, apoptosis and ROS generation. Moreover, EGPI-1 showed good safety and favorable pharmacokinetic properties in vivo. These observations demonstrate that EGPI-1 may serve as an excellent lead compound for the development of new anticancer drugs that target the eIF4E/eIF4G interface and as a chemical genetic probe to investigate the role of the eIF4E in biological processes and human diseases.
