Crosslinked linear polyethylenimine enhances delivery of DNA to the cytoplasm.
Crosslinked polyethylenimines (PEIs) have been frequently examined over the past decade since they can maintain the transfection efficiency of commercially available, 25k branched PEI, but exhibit less cytotoxicity. The argument is often made that the degradability of such polymers, generally synthesized with either disulfide or hydrolytically degradable crosslinkers, is critical to the high ef...
متن کاملPectin–Coated Polyethylenimine Polyplexes as Effective Gene Delivery Systems
Gene therapy is believed to be the therapy of the future because it aims to eradicate causes rather than symptoms of diseases. The generic aim of gene therapy is to deliver DNA inside cells in order to achieve a stable and regulated expression of transgenes in the target cells or tissues without side effects. Spontaneous entry of naked DNA inside cells is an inefficient process, consequently, a...
متن کاملHighly crosslinked, PEG-containing copolymers for sustained solute delivery.
Novel ionizable polymer networks were prepared from oligo(ethylene glycol) (OEG) multiacrylates and acrylic acid (AA) employing bulk radical photopolymerization techniques. The properties of these materials exhibited a complex dependence on the network structure and composition, and the materials were therefore used in the design of controlled release devices with precisely controlled propertie...
متن کاملInvestigating lipopolymers based on polyethylenimine and nanoliposome for gene delivery to prostate cancer (PC3) cell line
Background: Non-viral Nano carriers such as liposomes and cationic polymers based on engineered properties are regarded in gene delivery field. Although these carriers do not have weaknesses of viral vectors, but they are less efficient than viruses and they still need to be improved as favorable gene delivery carriers. Amongst non-viral carriers, cationic liposomes have been proposed for clini...
متن کاملPolyethylenimine-grafted polycarbonates as biodegradable polycations for gene delivery.
Polycations as one of non-viral vectors have gained increasing attentions. In this paper, polyethylenimine(PEI)-grafted polycarbonates (PMAC-g-PEIx) were synthesized as a kind of biodegradable polycations for gene delivery. Backbone polymer, poly(5-methyl-5-allyloxycarbonyl-trimethylene carbonate) (PMAC), was synthesized in bulk catalyzed by immobilized porcine pancreas lipase (IPPL). Then, PMA...
