Gold nanozyme comprising glycol chitosan and gold particles, and pharmaceutical composition for preventing or treating inflammatory bowel disease comprising same

Abstract

One aspect according to the present invention relates to: a gold nanozyme including glycol chitosan and gold particles; and a pharmaceutical composition for preventing or treating inflammatory bowel disease, the composition comprising the gold nanozyme. The gold nanozyme and the pharmaceutical composition comprising same according to one aspect of the present invention was found to inhibit the expression of inflammatory factors, inhibit the generation of reactive oxygen species (ROS) and reactive nitrogen species (RNS) inside cells, and reduce the production of nitric oxide (NO) inside cells. In addition, the gold nanozyme was found to inhibit the secretion of Hight Mobility Group Box 1 (HMGB1) when further including glycyrrhizin. In addition, the gold nanozyme and the composition comprising same were found to enable the recovery of the length, weight, etc., of damaged intestines, and thus can be used in the inflammatory bowel disease prevention and/or treatment industry/market.
