Lipid-87 is an ionizable lipid developed by Generation Bio, characterized by its tertiary amine group for pH-dependent protonation and dual C16/C17 aliphatic chains that enhance hydrophobic stability.As the core component (47.5–57.5 mol%) of stealth lipid nanoparticles (LNPs), Lipid87 enables extended blood circulation (>24-hour half-life vs. 30 min for conventional LNPs) by synergizing with steric-stabilizing polymers (e.g., DSG-PEG₂₀₀₀-OMe), achieves >95% encapsulation efficiency for mRNA/ceDNA with low cytotoxicity (IC₅₀ >100 μM), and drives liver-specific targeting (>80% hepatocyte transfection at 0.5 mpk), effectively restoring 40% FIX activity in hemophilia B models for over 7 days.
