Screening of a glycopolymer library for GM1 mimetics synthesized by the “carbohydrate module method”†
The “carbohydrate module method” is a promising approach for oligosaccharide mimetics using polymeric materials. However, it is difficult to predict the optimal structure for a particular oligosaccharide mimetic, and an efficient strategy for the synthesis and evaluation of glycopolymers is desirable. In this study, a screening of glycopolymers for the “carbohydrate module method” by a combination of photoinduced electron/energy transfer-reversible addition–fragmentation chain-transfer (PET-RAFT) polymerization and surface plasmon resonance imaging (SPRI) is demonstrated. The facile and fast screening of synthetic glycomimetics was achieved, and the glycopolymer with the optimal structure as a GM1 mimetic strongly interacted with the cholera toxin B subunit.
