摘要:
The invention relates to the use of Polycefin-LLL nanoconjugate as a means of cytoplasmic delivery of drugs. In one embodiment, the present invention provides a drug delivery molecule, comprising a polymerized carboxylic acid molecular scaffold covalently linked to L-leucylleucylleucine. In another embodiment, the Polycefin-LLL includes drug antisense morpholino oligos, targeting antibodies, and a pH-sensitive endosome escape unit. In addition, the drug could be siRNA, microRNA, and aptamer.
