COMPOSITIONS OF POLYPLEXES AND SAPONINS

Abstract

The invention lies in the field of delivery of nucleic acids into a cell. In particular, disclosed herein is a nucleic acid that is polyplexed with a polymeric scaffold, which is provided in combination with an endosomal escape-enhancing saponin that is covalently bound either to the polymeric scaffold or to a cell targeting ligand by a linker configured to release the saponin from the scaffold under conditions present in an endosome. The disclosed herein compositions and methods may be exploited in the treatment of various diseases and/or conditions by systemic delivery.
