    • PURPOSE: A spermine copolymer is provided to remarkably improve transduction effectiveness without cytotoxicity as a hexane-carrier, thereby capable of being used as a hexane-carrier for gene-therapy. CONSTITUTION: A spermine copolymer of which primary amine or secondary amine is combined with at least one acrylate terminal of a linker through an addition reaction is represented by chemical formula 1. A molecular weight of the copolymer is 3-15 kDa. Polyethyleneglycol, galactosylated polyethyleneglycol, folate, mannose, or a combination thereof is additionally combined to the spermine copolymer. A hexane-transfer composite is that a therapy hexane is combined with the spermine copolymer. The combination ratio of the therapy hexane and the spermine copolymer is 1:5 - 1:50.

    • PURPOSE: An FC-g-PEI copolymer is provided to function as effective cancer cell target shRNA delivery carrier due to excellent composite formation capability with shRNA and to ensure physiochemical properties suitable for an aerosol gene delivery system. CONSTITUTION: A folate-chitosan-graft-PEI(FC-g-PEI) copolymer is represented by chemical formula 1. In chemical formula 1, K is an integer of 20-200; X is an integer of 1-10; M is an integer of 10-100; and PEI is polyethyleneimine. The FC-g-PEI/DNA gene delivery complex is manufactured by the FC-g-PEI copolymers, wherein the DNA is siRNA or shRNA. An aerosol composition for treating lung cancer includes the FC-g-PEI/Akt1 shRNA gene delivery complex as an active ingredient.
    • 目的:提供FC-g-PEI共聚物作为有效的癌细胞靶向shRNA递送载体,因为与shRNA具有优异的复合物形成能力,并且确保适用于气溶胶基因递送系统的物理化学性质。 组成:叶酸 - 壳聚糖 - 接枝PEI(FC-g-PEI)共聚物由化学式1表示。在化学式1中,K为20-200的整数; X为1-10的整数; M为10-100的整数; PEI是聚乙烯亚胺。 FC-g-PEI / DNA基因递送复合物由FC-g-PEI共聚物制造,其中DNA是siRNA或shRNA。 用于治疗肺癌的气溶胶组合物包括作为活性成分的FC-g-PEI / Akt1 shRNA基因递送复合物。
