306Oi10 is a biodegradable, branched chain lipidoid developed for RNA delivery in lipid nanoparticles (LNPs). Interestingly, the unbranched analog was 10-fold less effective in delivering luciferase mRNA in mice. The increased potency is thought to be due to increased cone-shaped structure and protonation at endosomal pH resulting in enhanced endosomal escape. 306Oi10 has been used to co-deliver three mRNAs (firefly luciferase, mCherry, and erythropoietin). The LNPs derived from 306Oi10 were not immunogenic or toxic to the liver. Incorporation of DOTAP into 306Oi10 LNPs resulted in increased targeting of mRNA to pancreatic β cells via intraperitoneal injection in mice.
