| Targets |
Tri-GalNAc(OAc)₃ targets the Asialoglycoprotein Receptor (ASGPR). ASGPR is an endocytic receptor highly expressed on hepatocytes that specifically recognizes and binds glycoproteins with terminal galactose or N-acetylgalactosamine residues. The trivalent structure of Tri-GalNAc enables multivalent binding to ASGPR, achieving high-affinity targeting.

|---|---|
| ln Vitro |
- Protein Degradation Activity: As the ligand component of LYTACs, Tri-GalNAc significantly reduces target protein (e.g., EGFR, HER2) levels and inhibits downstream signaling pathways, such as EGFR-mediated Akt and MAPK signals.
- Antitumor Activity: In liver cancer cell models, Tri-GalNAc-based LYTACs degrade carcinogenic membrane proteins and inhibit tumor cell proliferation. |
| Cell Assay |
- Protein Degradation Assay: Hepatocellular carcinoma cells are seeded and treated with Tri-GalNAc-conjugated LYTAC compounds. Target protein (e.g., EGFR, HER2) degradation is assessed by Western Blot.
- Cell Proliferation Inhibition Assay: In liver cancer cell models, cells are treated with Tri-GalNAc-LYTAC, and cell viability changes are evaluated using MTT or CCK-8 assays. |

| Additional Infomation |
Selective protein degradation platforms have created new opportunities for therapeutic development and biological research. The first lysosome-targeting chimeras (LYTACs) promoted the degradation of extracellular and membrane proteins by bridging a target protein to the cation-independent mannose-6-phosphate receptor (CI-M6PR). In this study, we developed LYTACs that engage the asialoglycoprotein receptor (ASGPR), a liver-specific lysosome-targeting receptor, to degrade extracellular proteins in a cell-type-specific manner. We conjugated binders to a triantennary N-acetylgalactosamine (tri-GalNAc) motif that binds ASGPR, thereby driving protein downregulation. Degradation of the epidermal growth factor receptor (EGFR) by GalNAc-LYTAC attenuated EGFR signaling compared to inhibition with an antibody alone. Furthermore, we demonstrated that a LYTAC composed of a 3.4-kDa peptide binder linked to a tri-GalNAc ligand degrades integrins and reduces cancer cell proliferation. The use of a single tri-GalNAc ligand for site-specific conjugation on antibody scaffolds improved the pharmacokinetic profile of GalNAc-LYTACs in vivo. Thus, GalNAc-LYTACs represent a promising approach for cell-type-restricted protein degradation.
