GalNAc-L96 - A Key Molecule for Efficient RNA Targeted Delivery

Introduction to GalNAc-L96

GalNAc-L96 (CAS 1159408-62-4) is a triantennary N-acetylgalactosamine (GalNAc) ligand primarily used for the synthesis of GalNAc-siRNA. GalNAc is a specific ligand for ASGPR (Asialoglycoprotein Receptor), enabling liver-targeted delivery, which is a crucial aspect of modern RNA delivery technology.

Applications and Advantages of GalNAc-L96

  1. Precise Liver-Targeted Delivery: ASGPR is highly expressed on liver cell surfaces, allowing siRNA, antisense oligonucleotides (ASO), or other nucleic acid drugs conjugated with GalNAc-L96 to efficiently enter liver cells and enhance therapeutic effects.
  2. Enhanced Bioavailability of siRNA: Traditional siRNA delivery methods (such as lipid nanoparticles, LNPs) often lead to non-specific distribution, whereas GalNAc-conjugated siRNA (GalNAc-siRNA) enables more efficient and safer RNA interference (RNAi) therapy.
  3. Reduced Systemic Toxicity: Due to the high specificity of GalNAc delivery, compared to LNPs, GalNAc-siRNA exhibits lower immunogenicity and reduced side effects, making it a preferred strategy for RNA drug development.
  4. Improved Stability and Optimized Pharmacokinetics: By optimizing the structure of GalNAc-L96, its affinity for ASGPR can be enhanced, thereby increasing hepatic cell uptake and prolonging in vivo half-life.
