Process for preparing hyaluronic acid-peptide conjugate, and hyaluronic acid-peptide conjugate produced thereby

摘要

PURPOSE: A method for preparing hyaluronic acid-peptide conjugate is provided to apply to a drug delivery system of various peptide active ingredients with safety to human body. CONSTITUTION: A method for preparing hyaluronic acid-peptide conjugate comprises: a step of reacting tetra-n-butyl ammonium hydroxide(TBA-OH) with hyaluronic acid(HA), salt thereof, derivative thereof to form HA-TBA; a step of preparing water-insoluble peptide with terminal amino group; and a step of reacting the water-insoluble peptide with HA-TBA and terminal amino group under the presence of organic solvent.
