生医组合物;BIOMEDICAL COMPOSITION

摘要

本发明提供一种生医组合物，包括：一透明质酸；一经修饰之组胺酸；以及一聚合物或C4-C20烷类，其中该经修饰之组胺酸，与该聚合物或C4-C20烷类，接枝于该透明质酸之至少一个一级羟基上以与该透明质酸形成一透明质酸衍生物，且其中该经修饰之组胺酸之接枝率为约1-100%，而该聚合物或C4-C20烷类之接枝率为约0-40%。; a modified histidine; and a polymer or C4-C20alkane, wherein the modified histidine and the polymer or C4-C20alkane are grafted to at least one alcohol group of the hyaluronic acid to get along with the hyaluronic acid to form a hyaluronic acid derivative, wherein a graft ratio of the modified histidine is about 1-100%, and a graft ratio of the polymer or the C4-C20alkane is about 0-40%.
