The invention provides a diamine crosslinking agent for acidic polysaccharides consisting of a diamine compound having a primary amino group at both terminals and an ester or thioester bond in the molecule, wherein the number of atom in the linear chain between at least one of the amino groups and the carbonyl carbon in the ester or thioester is 1 to 5; in particular, a diamine crosslinking agent for acidic polysaccharides which is represented by the general formula (I) below:
[the symbols in the formula are as described in the specification]; a crosslinked acidic polysaccharide obtained by forming crosslinks by amide bonding between the amino groups in the diamine crosslinking agent and carboxyl groups in an acidic polysaccharide; and a medical material including the crosslinked product.
该发明提供了一种用于酸性多糖的二胺交联剂,其由一种二胺化合物组成,该化合物在分子中的两个末端具有主要氨基团,并且在至少一个氨基团与酯或硫酯中的羰基碳之间的线性链中的原子数为1至5;特别是一种用下面的通式(I)表示的酸性多糖的二胺交联剂:
[式中的符号如说明书中所述];通过在二胺交联剂的氨基团和酸性多糖中的羧基团之间形成酰胺键而获得的交联酸性多糖;以及包括所述交联产物的医用材料。
