  Polyamine Analogues of 3β-[N-(N′,N′-Dimethylaminoethane)carbamoyl]cholesterol (DC-Chol) as Agents for Gene Delivery

  摘要：

  Cationic liposomes are rapidly proving very effective at mediating the delivery of genes to cells in vitro. Moreover, the use of cationic liposomes for gene delivery in vivo is now under consideration. In previous work, we were able to demonstrate that cationic liposomes, formulated from 3 beta-[N-(N',N'-dimethylaminoethane)carbamoyl]cholesterol (DC-Chol) and the neutral phospholipid, dioleoyl L-alpha-phosphatidylethanolamine (DOPE), were able to transfect the lungs of mice in vivo. However, it rapidly became apparent that substantial improvements in the gene delivery efficiency, by approximately two orders of magnitude, would be needed for human lung transfection to be possible. In the following paper we describe the synthesis of a range of polyamine analogues of DC-Chol, which were formulated into cationic liposomes with DOPE and evaluated for efficiency of gene delivery in vitro and in vivo in mice. We report that cationic liposomes formulated from DOPE and the novel pentamine N-15-cholesteryloxycarbonyl-3,7,12-triazapentadecane-1,15-diamine (CTAP) were 100 times more efficient than DC-Chol/DOPE liposomes at gene delivery in vivo (500 times more effective than DNA alone). Therefore, we believe that CTAP/DOPE cationic liposomes should have clinical applications in human gene therapy approaches to the treatment of lung disorders as well as to other clinical conditions.
