QC-01-175 targets ZFP91, ZN653, ZN827 also degraded at 4 h, 1 μM in patient iPSC derived FTD neurons harboring MAPT A152T mutation.

QC-01-175 is a heterobifunctional molecule, which degrades aberrant tau. QC-01-175 reduces the levels of A152T and P301L mutant tau protein and protects neurons from tau-mediated toxicity and improve cell survival (Pink: ligand for target protein Aberrant tau ligand 1 (HY-W453397); Black: linker NH2-PEG3 (HY-W007545); Blue: ligand for E3 ligase Pomalidomide (HY-10984))[1][2].
