Description:	Tri-GalNAc-NHS ester is a LYsosome TArgeting Chimera (LYTAC) and a ligand of asialoglycoprotein receptor (ASGPR). ASGPR is a lysosomal targeting receptor specifically expressed on liver cells, for the degradation of extracellular proteins including membrane proteins. Tri-GalNAc-NHS ester can be used as a protein degrader and it can be used for the research of LYTAC.

DC60911	ASGPR ligand-1	ASGPR ligand-1 is a compound that targets the asialoglycoprotein receptor (ASGPR) and is utilized in various disease research contexts .
DC67352	C12-Diacid-Tri-GalNAc-COOH
DC67351	Tri-GalNAc(OAc)3 Cbz	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.
DC65965	Tri-GalNAc(OAc)3	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 was first reported in Nat Chem Biol. 2021 Sep;17(9):937-946 (compound ). This product has no formal name at the moment.
