生物可还原聚合物是一类以二硫键为主的高分子材料,由于其在细胞外生理条件下的高稳定性和生物还原引发的遗传物质释放,以及细胞内的还原性环境中含有大量还原性分子(如谷胱甘肽)而降低的细胞毒性,已成为理想的基因传递载体。本文综述了用于基因传递的生物可还原聚合物的起源和最新进展,包括可还原交联聚乙烯、多肽、聚离子复合物胶束和聚酰胺胺。尽管已经进行了大量的研究以显示出巨大的基因递送功效,但是仍然需要彻底回答关于药代动力学或安全性的几个重要问题,以进一步合理设计具有人类基因递送系统潜力的生物可还原聚合物。
Bioreducible polymers, which possess mainly disulfide linkages in the polymer structures, have appeared as ideal gene delivery carriers due to the high stability in extracellular physiological condition and bioreduction-triggered release of genetic materials, as well as decreased cytotoxicity because intracellular cytosol is a reducing environment containing high level of reducing molecules such as glutathione. This review will describe the initiation and recent advances in the development of bioreducible polymers for gene delivery, which includes reducibly cross-linked PEIs, polypeptides, polyion complex micelles, and poly(amido amine)s. There have been extensive researches performed to exhibit great gene delivery efficacy but still several important issues about pharmacokinetics or safety should be answered thoroughly for further rational design of bioreducible polymers having potentials in human gene delivery systems.
