摘要:
The present invention relates to a target-aiming drug delivery system for diagnosis and treatment of cancer containing liposome labeled with peptides which specifically targets interleukin-4 receptors, and a manufacturing method thereof. The liposome which contains anticancer drugs labeled with IL4RPep peptides prepared in accordance with the present invention can deliver drugs to cancer cells in which IL-4 receptors are overexpressed by IL4RPep peptides which specifically bind to IL-4 receptors, and the drug delivery can recognize cancer cells specifically by a label. Thus, IL4RPep peptides can increase the effect of drugs only on cancer tissues and at the same time significantly reduce the side effects on normal tissues, which makes possible in vivo(molecular) imaging and early diagnosis of tumors. Therefore, the liposome which contains anticancer drugs labeled with IL4Pep peptides of the present invention can be applied, as the target-aiming drug delivery system, effectively to the diagnosis and treatment of cancers.

The present invention relates to a novel protein skeletal module which increases the binding affinity or binding specificity of active polypeptides. More particularly, the present invention relates to a protein skeletal module comprising polypeptides consisting of the 1 st to 19 th amino acids of the amino acid sequence expressed in sequence number 1; polypeptides comprising active polypeptides; and polypeptides consisting of the 29 th to 86 th amino acids of the amino acid sequence expressed in sequence ID number 1. The present invention also relates to a method for preparing the protein skeletal module. The protein skeletal module of the present invention increases the binding affinity or binding specificity of active polypeptides embedded therein, and therefore is effective in diagnosing and treating diseases.

The present invention relates to a hydrophobic drug delivery conjugate, to which cyclodextrin, poly(maleic anhydride), and a hydrophobic drug are bonded, and to a pharmaceutical composition comprising the hydrophobic drug delivery conjugate as an active ingredient. The hydrophobic drug delivery conjugate according to the present invention can effectively control the release rate and the delivery rate of a hydrophobic drug by regulating the physicochemical bonding and/or composition of the cyclodextrin, poly(maleic anhydride), and hydrophobic drug, and can also increase the effect of the drug by significantly increasing the solubility of the hydrophobic drug. Further, the present invention can enable the type of the hydrophobic drug to be varied, as well as a peptide having target directivity to be introduced into a surface of the conjugate, such that the present invention can be applied to the treatment of various diseases in addition to cancer treatment.
