QZ2135

QZ2135 (compound 20) is a RET-targeted PROTAC degrader with in vivo antitumor properties in a Ba/F3-KIF5B-RET-G810C xenograft mouse model. The degradation activities of QZ2135 targeting KIF5B-RET have DC₅₀ values of 4.7 nM (WT), 17.2 nM (V804M), and 73.8 nM (G810C), respectively. QZ2135 is composed of a target protein ligand (red part) RET ligand-3 (HY-170853), an E3 ligase ligand (blue part) Lenalidomide-F (HY-W039233), and a PROTAC Linker (black part) 7-Iodohept-1-yne (HY-W587352), in which the target protein ligand + linker form a conjugate RET Ligand-Linker Conjugate-1 (HY-170854).
(Pink: RET ligand (HY-170853); Blue: Cereblon ligand (HY-W039233); Black: linker (HY-W587352)).
