PCT No. PCT/GB95/02706 Sec. 371 Date May 16, 1997 Sec. 102(e) Date May 16, 1997 PCT Filed Nov. 17, 1995 PCT Pub. No. WO96/15811 PCT Pub. Date May 30, 1996Composition comprising DNA associated with a polycation moiety wherein the polycation moiety is itself coupled to an integrin receptor binding moiety is disclosed. Preferably, the integrin receptor binding moiety is a peptide, and the compositions can be used to deliver DNA to a cell where it will be expressed, for example, to treat a condition by gene therapy. In a preferred embodiment, the integrin receptor binding moiety comprises a peptide, in particular a cyclic peptide, comprising the sequence RGD. In a particularly preferred embodiment, the peptide comprises the sequence GGCRGDMFGC. Cyclic configuration in this sequence is imposed by virtue of the presence of two cysteine residues which can form a disulphide bond. |
