POLYSACCHARIDE DERIVATIVE AND HYDROGEL THEREOF |
摘要 |
Disclosed are a polysaccharide derivative obtained by substituting some of the carboxyl groups of a carboxy polysaccharide with —NH—X—CO—Y—Z; and a hydrogel thereof. Here, X is a C1-10 hydrocarbon group, Y is a polyalkylene oxide having oxygen atoms at both ends, and Z is a C1-24 hydrocarbon group or —CO—R2, with R2 being a C1-23 hydrocarbon group. The hydrogel has excellent viscoelasticity and can be injected into a predetermined location with an injection device such as a syringe, and thus can be advantageously used as a medical gel or an adhesion barrier. |
