Abstract
Previously, we prepared cationic nanoparticles (NP and NP-N) composed of cholesteryl diamine (OH-Chol, (3S)-N-(2-(2-hydroxyethylamino)ethyl)cholesteryl-3-carboxamide) and cholesteryl triamine (OH-N-Chol, (3S)-N-(2-(2-(2-hydroxyethylamino)ethylamino)ethyl)cholesteryl-3-carboxamide), respectively, with Tween 80 for small interfering RNA (siRNA) delivery into tumor cells. In this study, we prepared NP-0.25 N composed of OH-Chol and OH-N-Chol at a molar ratio of 3/1 with Tween 80, and evaluated the transfection efficiency of plasmid DNA (pDNA) into tumor cells. NP-N exhibited lower transfection activity than NP; however, NP-0.25 N showed higher transfection activity than both NP and NP-N in various tumor cells. NP-0.25 N increased the amount of internalized pDNA by increased cellular association, and improved the escape from endosomes after clathrin-mediated endocytosis. The results of the experiments suggested that cholesteryl triamine may have potential as a helper lipid to increase the transfection for pDNA delivery by cationic cholesterol-based nanoparticles.
