DC67444	GalNAc Lipid 1005	GalNAc Lipid 1005 is a trivalent GalNAc-lipid conjugate designed for ASGPR-mediated hepatic delivery. It features a lysine-based scaffold covalently linked to three GalNAc moieties via a 44-unit PEG spacer, anchored by a 1,2-O-dioctadecyl-sn-glyceryl (DSG) lipid tail.
DC67443	GalNAc Lipid 1002	GalNAc Lipid 1002 is a trivalent GalNAc-lipid conjugate designed for ASGPR-mediated hepatic delivery. It features a lysine-based scaffold covalently linked to three GalNAc moieties via a 12-unit PEG spacer, anchored by a 1,2-O-dioctadecyl-sn-glyceryl (DSG) lipid tail.
DC67409	Galnac Lipid 83	Galnac Lipid 83 is developed by Prime Medicine Patent: WO2024220807.Galnac Lipid 83 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.
DC67408	Galnac Lipid 29
DC60502	GalNAc Lipid GL6(GalNAc Lipid 1004)	GL6 is a trivalent GalNAc-lipid conjugate designed for ASGPR-mediated hepatic delivery. It features a lysine-based scaffold covalently linked to three GalNAc moieties via a 36-unit PEG spacer, anchored by a 1,2-O-dioctadecyl-sn-glyceryl (DSG) lipid tail. This structure balances ligand accessibility (via optimized PEG length) and nanoparticle stability (via hydrophobic DSG anchoring). Compared to GL3 (TRIS scaffold, same PEG length), GL6’s simplified lysine scaffold improves manufacturability. In LDLR-deficient models, GL6 enabled 61% liver editing (vs. 5% with standard LNPs) at 2 mg/kg, demonstrating superior ASGPR targeting. Its design minimizes ligand crowding (0.05 mol% surface density) while maximizing endosomal escape and durable gene editing.
