摘要

Structure-activity relationship studies are pivotal in the development of existing small interfering RNA (siRNA) nanocarriers and in designing new delivery systems. In this paper, we investigated the ability of four dendritic polyglycerolamines (dPG-NH2) with increasing amine degree of functionalization (DF) on dendritic polyglycerol (dPG) to compIex DNA by a coupled in silico/in vitro approach. In parallel, we examined our dPG-NH2 analogues for siRNA complexation, cytotoxicity, and transfection efficiency in vitro and in vivo. Our simulation data indicate the most effective nucleic acid affinities for dPG-NH2 anaIogues with DF >= 50%. Concomitanty, the results of in vitro and in vivo transfection studies aka demonstrate efficient siRNA transfection orgy for those dPG-NH2 anaIogues with DF >= 50%. Thus, both MD simuIation and siRNA knockdown studies show that a minimum DF per dPG unit (namely 50% on a 10 kDa dPG) is needed to achieve efficient siRNA interaction and successful transfection.
