Field of application
XH-04 (Lipid#4)​​ is an ionizable lipid engineered for advanced mRNA delivery developed by ​​JiaChen West Lake Biotech. Its core structure features a central benzene ring with asymmetric hydrophobic tails (C9-C10 chains) and pH-responsive tertiary amines that enable efficient mRNA encapsulation and endosomal escape. As detailed in CN113993839A, XH04 outperforms industry benchmarks (e.g., MC3 lipid), boosting protein expression by ​​>10-fold​​ in BHK cells. In PCT/CN2024/121624, JiaChen further demonstrated its utility in lung-targeted LNPs (tLNP/tLCNP). When combined with cationic lipids (e.g., DOTMA at 2:1 molar ratio), XH 04 redirects >80% of mRNA delivery to murine lungs—overcoming liver tropism—while maintaining low toxicity. The lipid’s benzenic core and optimized alkyl chain geometry (patent claims 1-9) are credited for enhanced endosomal disruption and mRNA release kinetics. JiaChen’s innovations position XH-04 as a cornerstone for next-generation mRNA therapeutics.
