We newly prepared a polyion complex of DNA with lipoglutamide, N,N′-bis(18-hydroxy-7,10,13,16-tetraoxaoctadecyl)-L-glutamide hydrochloride (abbreviated to 2EO4C6N+). Formation and characterization of the DNA/2EO4C6N+ complex were investigated by elemental analysis, melting temperature, and light-scattering measurements. Compaction of DNA by binding with the cationic 2EO4C6N+ was seen by multi-angle light scattering. Aggregation of the DNA/2EO4C6N+ complex was significantly depressed compared with the DNA complex without tetraethylene glycol. The DNA/2EO4C6N+ complex had low cytotoxicity and efficient internalization into tumor cells compared with native DNA.
