英文摘要	The eIF4E/eIF4G complex plays a central role in gene expression regulation during the initial stage of translation. This study aimed to determine if the novel small molecule compound, TPDHT, could disrupt the interaction of eIF4E/eIF4G, and if it could exhibit excellent antitumor activity in vivo without causing apparent toxicity effect. This study investigated the antitumor mechanism of TPDHT in vitro and in vivo. TPDHT showed significant anti-proliferative activity on human lung cancer A549 cells, and it induced G0/G1 cycle arrest. Moreover, TPDHT also induced A549 cell apoptosis through the mitochondria-mediated apoptotic pathway. Our results indicate that TPDHT could disrupt the interaction of eIF4E/eIF4G, and the activity of eIF4F plays an important role in TPDHT-induced cell proliferation inhibition and apoptosis. Further research showed that TPDHT could inhibit the Ras/ERK/MNK pathway, and activation of the ERK pathway reversed TPDHT-induced cell proliferation inhibition and apoptosis. Taken together, our study findings indicated that TPDHT exerts an antitumor effect through an intrinsic apoptotic pathway controlled by the ERK/MNK/eIF4F pathway.
