ALK degrader 1

ALK degrader 1 is a potent, hydrophobic tag (HyT)-based degrader that induces ubiquitin-proteasome system (UPS)-dependent EML4-ALK degradation (DC50 = 0.13 μM). ALK degrader 1 demonstrates potent ALK degradation and antiproliferative effects in ALK-dependent cell lines, while showing minimal cytotoxicity in ALK fusion-negative cells. ALK degrader 1 triggers cell cycle arrest at the G0/G1 phase and stimulates apoptosis. ALK degrader 1 not only facilitates efficient degradation of the ALK protein but also disrupts key downstream effectors, including the STAT3 signaling axis. ALK degrader 1 mediates robust EML4-ALK degradation in vivo. ALK degrader 1 can be used for ALK-related diseases research.
