Tri-GalNAc(OAc)3 TFA is a tri-GalNAc ligand that can be used for the synthesis of GalNAc-LYTAC. GalNAc-LYTAC engages the asialoglycoprotein receptor for targeted protein degradation. tri-GalNAc: triantenerrary N-acetylgalactosamine; LYTAC: lysosome-targeting chimera.

Tri-GalNAc(OAc)3 is a triantenerrary N-acetylgalactosamine (tri-GalNAc) with an amino group, which is useful precursor for synthesis of GalNAc-LYTAC that engage the asialoglycoprotein receptor for targeted protein degradation.

Tri-GalNAc(OAc)3 Cbz is a ligand for asialoglycoprotein receptor (ASGPR) where the sugars are protected by acetylation and the tris tertiary amine is protected by benzyloxycarbonyloxy (Cbz). This peracetylated tri-GalNAc(OAc)3 Cbz can be serve as a valuable building block for ASGPR-targeted therapies. Its three branches or arms, each ending in a GalNAc sugar, ensure strong binding to hepatocyte ASGPR. However, the key feature lies in its protective groups: acetylated sugars allow for controlled removal to expose reactive sites for conjugation, while the Cbz-protected amine provides stability and can be selectively cleaved to introduce a reactive amine group for further biomolecule attachment, ultimately enabling researchers to tailor tri-GalNAc(OAc)3 Cbz into customized conjugates for specific therapeutic applications.

MS41 is a selective eleven-nineteen leukemia (ENL) PROTAC degrader, with DC50s of 3.50 nM (MV4;11), 2.84 nM (SEMK2), 3.03 nM (Jurkat), and 26.58 nM (KASUMI1), respectively.
