Abstract
The present invention provides alginic acid derivatives represented by formula (I) and formula (II), and a novel crosslinked alginic acid obtained by carrying out a Huisgen reaction using an alginic acid derivative of formula (I) and an alginic acid derivative of formula (II). There are thereby provided novel alginic acid derivatives and a novel crosslinked alginic acid.
Claims18
An alginic acid derivative of formula (II) below, consisting of an azide group introduced via an amide bond and a divalent linker (-L2-) at any one or more carboxyl groups of alginic acid:
- in formula (II), (ALG) is alginic acid;
- —NHCO— is an amide bond via any carboxyl group of alginic acid;
- and -L2- is a divalent linker selected from the group consisting of the following partial structural formula, excluding the parts outside the cutting lines at both ends of each formula:
An alginic acid derivative selected from the group consisting of the following formula:
- wherein in each formula, (ALG) is alginic acid;
- —NHCO— bound to (ALG) is an amide bond via any carboxyl group of alginic acid.
