Unsaturated hyaluronate tetrasaccharide and preparation method thereof
-
Paragraph 0040; 0041; 0046-0048, (2019/10/01)
The invention relates to unsaturated hyaluronate tetrasaccharide and a preparation method of unsaturated hyaluronate tetrasaccharide. Unsaturated hyaluronate tetrasaccharide is an ionic compound; a negative ion structure general formula of unsaturated hyaluronate tetrasaccharide is shown as formula (1) as shown in the specification; and X is hydrogen or methyl. Sites 4 and 5 of terminal glucuronicacid are set as unsaturated double bonds, so that unsaturated hyaluronate tetrasaccharide has as strong water absorptivity as common hyaluronic acid and stronger oxidation resistance.

A new and efficient Ionic Liquid-Supported Oligosaccharide Synthesis (ILSOS) strategy for an N-linked core pentasaccharide on a 10 g scale is reported. This new ILSOS includes a new spacer for an IL support, a new tagging strategy, and fast, efficient and orthogonal removal of the ionic-liquid support, producing the N-linked core pentasaccharide with direct applicability potential in a short time, with high yield and on a large gram scale.
