摘要： Novel cationic amphiphiles are provided that facilitate transport of biologically active (therapeutic) molecules into cells. By this invention, such cationic amphiphile is used in a state in which it is capable of accepting additional protons, i.e., it is not fully protonated. For purposes of this invention, cationic amphiphiles may be considered to encompass four general categories: (A) T-shaped/steroid-based amphiphiles; (B) T-shaped/non steroid-based amphiphiles; (C) non T-shaped/steroid based amphiphiles and (D) non T-shaped/non steroid-based amphiphiles.

摘要： Novel cationic amphiphiles are provided that facilitate transport of biologically active (therapeutic) molecules into cells. The amphiphiles contain lipophilic groups derived from steroids, from mono or dialkylamines, or from alkyl or acyl groups; and cationic groups, protonatable at physiological pH, derived from amines, alkylamines or polyalkylamines. There are provided also therapeutic compositions prepared typically by contacting a dispersion of one or more cationic amphiphiles with the therapeutic molecules. Therapeutic molecules that can be delivered into cells according to the practice of the invention include DNA, RNA, and polypeptides. Representative uses of the therapeutic compositions of the invention include providing gene therapy, and delivery of antisense polynucleotides or biologically active polypeptides to cells. With respect to therapeutic compositions for gene therapy, the DNA is provided typically in the form of a plasmid for complexing with the cationic amphiphile.Novel and highly effective plasmid constructs are also disclosed, including those that are particularly effective at providing gene therapy for clinical conditions complicated by inflammation. Additionally, targeting of organs for gene therapy by intravenous administration of therapeutic compositions is described.
