摘要:
A novel class of ionizable lipid compounds as well as lipid nanoparticles comprising said ionizable lipid compounds is provided. Advantageously, upon hydrolysis of an internal ester bond, which is likely to occur under typical in vivo conditions, a zwitterionic lipid structure is obtained, which is no longer capable of complexing a nucleic acid, which will thus be released from the lipid nanoparticle and subsequently is able to perform its therapeutic function.
