Synthesis, Characterization, and Medical Applications of Hyaluronic Acid Derivatives |
초록 |
Hyaluronic acid (HA) is a biodegradable, biocompatible, non-immunogenic and linear polysaccharide which has been widely used for various medical applications. On the basis of real-time bio-imaging of HA derivatives in the body using quantum dots (QDots), highly modified HA derivatives were applied for a long acting conjugation of biopharmaceuticals and slightly modified HA derivatives were applied for targeted drug delivery to the tissues with HA receptors, such as the liver and tumors. The half-life of erythropoietin (EPO) conjugated with 20K stealth HA was comparable to that of 40K PEGylated EPO. Intratumoral injection of anti-VEGF siRNA/PEI-HA complex with 24 mol% PEI content resulted in the effective inhibition of tumor growth by HA receptor mediated endocytosis to B16F1 tumor cells in C57BL/6 mice. Furthermore, the degradation controlled stealth HA was successfully applied for tissue engineering applications such as tissue augmentation and guided bone regeneration. |
