The present invention is directed to a photoreactive polysaccharide which comprises hyaluronic acid covalently bonded to a glycidyl ester of the photoreactive compound represented by the formula (I):
wherein R1-CO- represents a residue of a photoreactive compound having the carboxyl group(s) identified, and an unsaturated carbon double bond, selected from the group consisting of cinnamic acid, thiopheneacrylic acid, cinnamylideneacetic acid and sorbic acid, a photocrosslinked polysaccharide produced by crosslinking the above-mentioned polysaccharide by light irradiation, as well as a medical product comprising the same. Preferably the medical product is an anti-adhesive agent for a substrate for sustained drug release or a substrate for culturing cells.
本发明涉及一种光活性多糖,它包括与式 (I) 所代表的光活性化合物的缩水甘油酯共价键合的透明质酸:
其中 R1-CO- 代表光活性化合物的残基,该化合物具有所确定的羧基和不饱和碳双键,该化合物可从肉桂酸、噻吩丙烯酸、亚肉桂基乙酸和山梨酸组成的组中选择;通过光照射交联上述多糖而产生的光交联多糖;以及包含上述多糖的医疗产品。该医疗产品最好是用于药物持续释放基质或细胞培养基质的抗粘剂。
