PROTAC MNK1 degrader-1

ROTACMNK1degrader-1 is a selective MNK1 PROTAC degrader with a DC50 of 11.92 nM and a Dmax greater than 96% in MV4-11 cells. It significantly reduces p-eIF4E levels with an IC50 of 22.07 nM, induces apoptosis, and causes cell cycle arrest at the G1 phase. This compound exhibits potent antitumor activity, demonstrating strong anti-leukemic effects in MV4-11 xenograft mouse models with acceptable drug safety.
