PURPOSE: A drug delivery system using hyaluronic acid - peptide conjugate micelle Is provided to be applied to human body by being filled in biodegradable derivative. CONSTITUTION: A drug delivery system is composed of a shell domain which includes hyaluronic acid or pharmaceutically acceptable salt and a core domain which includes water-immiscible peptides. The water-immiscible peptide comprises micelle combined with pharmaceutically acceptable salt or hyaluronic acid and water-immiscibility drug filled inside the micelle. The hyaluronic acid or the pharmaceutically-acceptable salt thereof has the molecular weight of 10,000-3,000,000 daltons(Da). The hyaluronic acid or the pharmaceutically-acceptable salt thereof is a compound represented by chemical formula 1. The water-immiscibility peptide is combined as the number of molecules corresponding to 4-15% of integers of monomer number per each molecule of the chemical formula 1. |
