Abstract
The oligonucleotide derivative of the present invention is represented by Formula (1). This derivative is considered to be introduced into cells by binding of its amino sugar chain moiety to a ligand on cell surfaces, and have selective drug delivery function. The oligonucleotide derivative can be easily synthesized and introduced into cells without using a lipofection reagent. wherein A and B are independently modified or unmodified oligonucleotides whose total chain length is 3 or more, and A and B do not contain hydroxyl groups at 3' and 5′ ends of the oligonucleotide; S represents a sugar substituent, a peptide chain, or a tocopherol-binding group; and an alkyl group may be bound instead of hydrogen bound to a benzene ring.
