Abstract:
A physiologically active effective ingredient or a drug delivery carrier comprising an AP-GRR peptide is provided to exert the cell permeation property of the AP-GRR peptide effectively by exposing the AP-GRR peptide portion on the surface thereof, thereby increasing the bioavailability of the physiologically active effective ingredient. An AP-GRR peptide as a cell permeation peptide includes a sequence of Gly(Arg)n Gly Tyr Lys Cys(n is 1 to 20). A drug delivery carrier comprises a lipid structure or a polymeric particle which is covalently bonded to the peptide or a peptide chain including the peptide. The carrier further comprises a stabilizer. A pharmaceutical composition comprises the drug delivery carrier with 0.01-30 wt.% of a physiologically active effective ingredient regarding the total weight of the polymeric particle of liposome dispersion or an emulsion.
