GalNAc

N-acetylgalactosamine (GalNAc) is a ligand widely used for hepatocyte-targeted delivery of oligonucleotide therapeutics. GalNAc conjugates typically employ a triantennary structure that binds with high affinity to the asialoglycoprotein receptor (ASGPR) expressed on hepatocytes. After receptor recognition, the conjugate is internalized through receptor-mediated endocytosis, allowing efficient uptake of siRNA or antisense oligonucleotides by liver cells. This targeted delivery strategy significantly enhances intracellular exposure while reducing systemic distribution.

GalNAc conjugation has become a leading delivery strategy for liver-targeted RNA therapeutics due to its high specificity, favorable pharmacokinetics, and convenient subcutaneous dosing. The platform enables potent gene silencing with lower doses and improved safety profiles. With multiple approved therapies and an expanding pipeline, GalNAc technology continues to support the development of next-generation oligonucleotide drugs for metabolic, genetic, and rare liver diseases.
