The invention relates to a novel ionizable cationic lipid family incorporating silicon, which belongs to the trademark LipexSil™ 1st generation lipids wherein at least one of the two side chains contains silyl acetal linker. Lipids containing silyl acetal linker(s) so far are unprecedented in the art and are effective as ionizable cationic lipids in the formulation of empty or loaded lipid nanoparticles (LNPs). The novel linkers according to the invention are designed by means of borane catalysts [WO 2022/129966]. The invention describes the synthesis of the lipids of formula (I), formation and characterization of nanoparticles and biological experiments demonstrating that the lipid nanoparticles prepared with these novel lipids can efficiently deliver their cargo (e.g. RNA, DNA, mRNA, siRNA, pDNA, circular DNA, small biologically active molecules) into the cells.
