Galnac Lipid 83 is from Prime Medicine Patent: WO2024220807.Compound 83 is a GalNAc-conjugated lipid designed for targeted liver delivery. It features a triantennary GalNAc ligand linked via a PEG spacer (e.g., -(CH2CH2O)n-) to a branched hydrophobic tail (C18 alkyl chains). The structure includes amide/ester bonds for stability and a stereospecific configuration (R/S) to optimize ASGPR receptor binding. Integrated into lipid nanoparticles (LNPs), it enhances hepatic uptake of nucleic acids (e.g., mRNA, gene editors) by leveraging ASGPR-mediated endocytosis. Its design balances hydrophilicity (PEG) and lipophilicity (alkyl chains) for efficient encapsulation and in vivo delivery, supporting therapeutic applications in liver-specific gene editing or RNA therapies.
