Title:
DIAMINE CROSSLINKING AGENT, ACIDIC POLYSACCHARIDE CROSSLINKED BODY, AND MEDICAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/115609
Kind Code:
A1
Abstract:
Provided are the following: a diamine crosslinking agent for an acidic polysaccharide, the crosslinking agent comprising a diamine compound which has primary amino groups at both terminals and intramolecular ester or thioester bonds and in which the number of atoms in the straight chain between at least one of the amino groups and the carbonyl carbon of the ester or thioester is 1 to 5; in particular, a diamine crosslinking agent for an acidic polysaccharide represented by general formula (I) (where each symbol in the formula is as defined in the Specification); an acidic polysaccharide crosslinked body formed by amide bond crosslinking between the amino groups of the diamine crosslinking agent and the carboxy groups of an acidic polysaccharide; and a medical material comprising the crosslinked body.
