摘要:
Pharmaceutical compositions comprising a nucleic acid, a gene delivery polymer, and at least one adjunctive chemotherapeutic drug for the treatment of mammalian cancer or hyperproliferative disorders and methods of using thereof for the treatment of mammalian cancer or hyperproliferative disorders by intratumoral, intraperitoneal or systemic injection.
摘要:
A biodegradable cationic lipopolymer comprising a polyethylenimine (PEI), a lipid, and a biocompatible hydrophilic polymer, wherein 1) the lipid and the biocompatible hydrophilic polymer are directly linked to the PEI backbone or 2) the lipid is linked to the PEI backbone through the biocompatible hydrophilic polymer. The cationic lipopolymers of the present invention can be used for delivery of a nucleic acid or any anionic bioactive agent to various organs and tissues after local or systemic administration.

摘要:
Polymeric conjugates that can be used for targeted gene delivery comprising a poly(ethylene glycol) (PEG) grafted cationic polymer and a targeting moiety (TM), wherein 0.1 to 10 mole percent of the cationic groups of the cationic polymer are substituted with said PEG-TM.
摘要:
A biodegradable cross-linked cationic multi-block copolymer of linear polyethylenimine (LPEI) wherein the LPEI blocks is linked together by hydrophilic linkers with a biodegradable disulfide bond and methods of making thereof. The biodegradable cross-linked cationic multi-block copolymer may also contain pendant functional moieties which are preferably receptor ligands, membrane permeating agents, endosomolytic agents, nuclear localization sequences, pH sensitive endosomolytic peptides, chromogenic or fluorescent dyes.

摘要:
A biodegradable, novel cationic copolymer comprising a poly(alkylenimine)(PAI), a hydrophilic polymer, and a biodegradable linker, wherein the biodegradable linker covalently links the PAI and the hydrophilic polymer. The biodegradable cationic copolymers in the present invention can be used in drug delivery and are especially useful for delivery of a nucleic acid or any anionic bioactive agent to various organs and tissues after local or systemic administration.
