Synthesis of large polysaccharides facilitates identification of an active glycan domain

A preactivation-based one-pot glycosylation strategy was used to synthesize RN1 — a polysaccharide comprising 140 monosaccharide units isolated from Panax notoginseng, as well as a glycan fragment library. Evaluation of the biological activity of the glycans in vitro revealed that a decasaccharide fragment shows anti-pancreatic cancer activity.
