Title:
PHOSPHORYL MANNOSE PENTASACCHARIDE AND DERIVATIVES THEREOF, AND PREPARATION METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/071152
Kind Code:
A1
Abstract:
Provided are a phosphoryl mannose pentasaccharide as shown in formula (I) and derivatives of the phosphoryl mannose pentasaccharide as shown in formulas (II)-(XI), and a preparation method thereof. In the preparation method of this invention, by means of designing the hydroxy protective group of the mannose thioglycoside donor to regulate the reactivity, side reactions in the glycosylation reaction are few, and the reaction yield is high, thus being suitable for large-scale modular synthesis. The phosphoryl mannose pentasaccharide and derivatives thereof in the present invention have the activity for inhibiting angiogenesis, and have an application prospect as anti-tumour drugs.
