Lipid 11 (Compound Lipid 1) is a cationic lipid designed for nucleic acid delivery. It forms lipid nanoparticles (LNPs) through electrostatic interactions with nucleic acids, such as ceDNA. By using its cationic amine groups, Lipid 11 complexes with negatively charged nucleic acids, enabling cellular uptake and release of the nucleic acid cargo. Lipid 11 shows potential for use in the development of gene therapy drug delivery systems.
