Diamine crosslinker, acid polysaccharide crosslinker, and medical material |
| abstract |
The present invention provides a diamine crosslinking agent having a biodegradation point, an acidic polysaccharide crosslinked product obtained by directly condensing a crosslinking agent and a carboxy group of an acidic polysaccharide, and an adhesion preventing agent comprising the acidic polysaccharide crosslinked product. A crosslinked acidic polysaccharide formed by crosslinking a primary amino group of a polyamine and a carboxy group of an acidic polysaccharide by an amide bond, wherein the polyamine has a primary amino group at a terminal. A crosslinked acid polysaccharide having an ester or thioester in the molecule and having the carbonyl carbon of the ester or thioester on a straight chain between terminal primary amino groups. The polyvalent amine is a diamine, and the number of linear atoms between at least one of the primary amino groups at both ends of the diamine and the carbonyl carbon of the ester or thioester is 1 to 5. The acidic polysaccharide is chondroitin sulfate or a salt thereof. [Selection diagram] None |
