Abstract: RNA interference (RNAi) is a promising tool to regulate gene expression by external double stranded RNAs (dsRNAs) such as siRNAs. As an efficient method to deliver siRNAs to liver cells, we propose a novel strategy using vitamin E (VE)-conjugated neomycin derivatives. With the aim of delivering RNAi-based drugs to liver cells, several tripod-type and prodrug-type neomycin derivatives were synthesized, all of which were thermodynamically stabilized RNA duplexes. The prodrug-type derivative 7 and the tripod-type derivative 10 were delivered to liver cancer cells and successfully induced RNAi activity. These results indicated the potential use of natural aminoglycosides as carriers of RNAi drugs.
