The present invention describes a synthetic non-viral vector composition for gene therapy and the use of such compositions for in vitro, ex vivo and/or in vivo transfer of genetic material. The invention proposes a pharmaceutical composition containing 1) a non-cationic amphiphilic molecule or macromolecule and its use for delivery of nucleic acids or 2) a cationic amphiphilic molecule or macromolecule that transforms from a cationic entity to an anionic, neutral, or zwitterionic entity by a chemical, photochemical, or biological reaction and its use for delivery of nucleic acids. Moreover this invention describes the use of these non-viral vector compositions in conjunction with a surface to mediate the delivery of nucleic acids. An additional embodiment is the formation of a hydrogel with these compositions and the use of this hydrogel for the delivery of genetic material. A further embodiment of this invention is the use of a change in ionic strength for the delivery of genetic material.
本发明描述了一种用于基因治疗的合成非病毒载体组合,以及这种组合在体外、体内和/或体外转移遗传物质中的应用。该发明提出了一种包含1)非阳离子性两性分子或大分子的药物组合物及其用于传递核酸或2)由化学、光化学或生物反应从阳离子实体转变为阴离子、中性或带电离子实体的两性阳离子分子或大分子的药物组合物,以及其用于核酸传递。此外,本发明描述了这些非病毒载体组合物与表面结合以介导核酸传递的应用。另一实施例是使用这些组合物形成水凝胶,并利用该水凝胶传递遗传物质。本发明的另一实施例是利用离子强度变化传递遗传物质。
