A novel class of metal-directed supramolecular DNA-delivery systems

Abstract

The bis-complexes [Cu(L(dt))(2)](OTf)(2) (1) and [Cu(L(ot))(2)](OTf)(2) (2), where L(dt) = 1-dodecyl-1,4,7-triazacyclononane, L(ot) = 1-octadecyl-1,4,7-triazacyclononane and OTf = trifluoromethanesulfonate, formed a novel class of metallo-liposomes in water that transfect pEGFP-N1 plasmids into HEK 293-T cells at 38% and 4% efficiency, respectively.
