Abstract

Recently, proteolysis targeting chimera (PROTAC) technology is highlighted in drug discovery area as a new therapeutic approach. PROTAC as a heterobifunctional molecule is comprised of two ligands, which recruit target protein and E3 Ligase, respectively. To degrade the anaplastic lymphoma kinase (ALK) fusion protein, such as NPM-ALK or EML4-ALK, we generated several ALK-PROTAC molecules consisted of ceritinib, one of the ALK inhibitors, and ligand of von Hippel-Lindau (VHL) E3 Ligase. Among these molecules, TD-004 effectively induced ALK degradation and inhibited the growth of ALK fusion positive cell lines, SU-DHL-1 and H3122. We also confirmed that TD-004 significantly reduced the tumor growth in H3122 xenograft model.
