Abstract: The invention provides for polycations for condensation and delivery of polynucleotides to cells. Processes for forming the polycations by the polymerization of formamide monomers is also described.

Abstract: Disclosed is a process for providing for expression of an exogenous nucleic acid in an extravascular parenchymal cell of a mammal. The nucleic acid is inserted into a vessel of a mammal and the permeability of the vessel is increased. Increasing permeability of the vessel allows delivery of the nucleic acid to an extravascular parenchymal cell.

Abstract: Polyampholyte are able to condense nucleic acid to form small complexes which can be utilized in the delivery of nucleic acid to mammalian cells. The polyampholytes can be formed prior to interaction with nucleic acid or they can be formed in the presence of nucleic acid. Stabilized polycation/nucleic acid complexes can be modified to reduce the positive charge of the polycation and add targeting ligands without destabilizing the complex. The resultant particles retain their small size and are more effective in delivery of nucleic acid to cells in vivo.

Abstract: A process for delivering a polynucleotide into a parenchymal cell in a mammal, comprising, transporting the polynucleotide into a vessel communicating with the parenchymal cell in tissue or organ of the mammal such that the polynucleotide is transfected into the parenchymal cell. More specifically, the polynucleotide consists of a viral vector.

Abstract: An polyampholyte is utilized in a condensed polynucleotide complex for purposes of nucleic acid delivery to a cell. The complex can be formed with an appropriate amount of positive and/or negative charge such that the resulting complex can be delivered to the extravascular space and may be further delivered to a cell.

Abstract: Described are drug formulations that increase regional delivery of the drugs to cells. Methods for reversibly increasing the hydrophobicity of a drug through hydrolytic ally labile attachment of a hydrophobic moiety and methods for delivering the modified drug to cells is described. Hydrophobic modification increases drug delivery, while lability minimizes entry of the drug into non-target cells.

Abstract: The present invention relates to methods for delivering a genetic immunogen comprising a polynucleotide capable of expressing an antigen. The polynucleotide is delivered to the host via an intravascular route resulting in delivery to extravascular cells, expression of an encoded antigen and induction of an antigen-specific immune response. The methods may be used to enhance an immune response against a cancer cell related antigen.

Abstract: A labile disulfide-containing compound under physiological conditions containing a labile disulfide bond and a transduction signal.

Abstract: Chelator containing compounds are utilized in the delivery of molecules, polymers, nucleic acids and genes to animal cells. At least one chelator such as crown ether is attached to a polymer and then associated with another polymer such as DNA. An ion is then added to the mixture thereby forming condensed DNA. In condensed form and in complex with the chelator, DNA can be delivered to a cell.

Abstract: Disclosed is a process for functionally distributing genetic material to mammalian limb muscle cells comprising inserting genetic material into a limb vessel. Delivery efficiency and distribution is enhanced by combining injection of a solution containing the genetic material with the use of an externally applied cuff to increase vascular permeability.
