摘要: A unit structure-type pharmaceutical composition includes a single nucleic acid, such as an antisense nucleic acid, electrostatically bound to a single block copolymer having a cationic polyamino acid segment and a hydrophilic polymer chain segment. The negative charges of the nucleic acid are counterbalanced, at least substantially, by the positive charges of the cationic polyamino acid segment such that the pharmaceutical composition is electrically neutral or nearly electrically neutral. Further, the nucleic acid is covered with the hydrophilic polymer chain segment. The block copolymer thereby improves the blood retention capability of the nucleic acids.

A total quantity of positive charges derived from side chains of the cationic poly(amino acid) segment of the block copolymer in the unit-type polyion complex is not offset by a total quantity of negative charges derived from the nucleic acid. Furthermore, the nucleic acid has a strand length of 10-50 bases, the molecular weight of the poly(ethylene glycol) segment is 40×103 or more, and the block copolymer has a binding constant (Ka) for the nucleic acid of 3.0×105 or more.
