Composition for delivery of compounds to cells

摘要

The present invention provides cationic polymers that include a primary amine and a targeting group covalently bound to the primary amine, wherein the targeting group targets a cell of interest by interacting with the surface of the cell. The invention also provides molecular complexes that include a polyethyleneimine and a targeting group covalently bound to a primary amine of the polyethyleneimine, and a biologically active compound. The invention further provides methods for delivering a biologically active compound to a vertebrate cell.
