摘要： Linear polyethylenimine was modified with sterols, such as cholesterol, in three different geometries: linear shaped (L), T-shaped (T), and a combined linear- and T-shaped (LT), to result in linear polyethylenimine-sterol conjugates. These conjugates were mixed with nucleic acids to form complexes for delivery of the nucleic acids into cells. Mammalian cells transfected with these complexes showed protein expression levels higher than linear polyethylenimine alone, and twice that of branched polyethylenimine, but without any significant loss in cell viability. Methods of making these compositions and methods of using them for gene delivery are also described.

摘要： Polyplex formulations were prepared using p(TETA/CBA), its PEGylated analog, p(TETA/CBA)-g-PEG2k, and mixtures of the two species at 10/90 and 50/50 wt %, respectively. Increasing PEG wt % inhibited polyplex formation. This work demonstrates the feasibility of preparing homogenous polyplexes by altering the PEG wt % using a mixture of p(TETA/CBA) and p(TETA/CBA)-g-PEG2k products. Further, a single-step method of making p(TETA/CBA)-g-PEG2k is disclosed.

摘要： An arginine-grafted bioreducible poly(disulfide amine) (“ABP”) as a reagent for efficient and nontoxic gene delivery is described.

ABP exhibits much higher transfection efficiency than polyethyleneimine in mammalian cells and exhibits no cytotoxicity.
