The present invention relates to a hyaluronic acid derivative in which an anti-inflammatory drug is bound via a covalent bond, wherein the structure of the hyaluronic acid derivative is represented by following formula (4) or (5):
HA-SP-NSAID (4)
HA-SP-DMARD (5)
wherein HA represents a hyaluronic acid chain; SP represents a spacer residue; NSAID represents a non-steroidal anti-inflammatory drug residue, DMARD represents a disease-modifying anti-rheumatic drug residue, and - represents the covalent bond, wherein the spacer binds to a carboxyl group of the hyaluronic acid via an amide bond and the anti-inflammatory drug selected from non-steroidal anti-inflammatory drugs and disease-modifying anti-rheumatic drugs binds to the spacer via an ester bond, an amide bond or a thioester bond.
本发明涉及一种透明质酸衍生物,其中通过共价键结合了一种抗炎药物,其中透明质酸衍生物的结构由以下公式(4)或(5)表示:
HA-SP-NSAID (4)
HA-SP-DMARD (5)
其中HA代表透明质酸链;SP代表间隔基团;NSAID代表非甾体抗炎药残基,DMARD代表改善疾病的抗风湿药物残基,-代表共价键,其中间隔基通过酰胺键与透明质酸的羧基结合,并且选自非甾体抗炎药物和改善疾病的抗风湿药物的抗炎药物通过酯键、酰胺键或硫酯键与间隔基结合。
