The use of ionic liquid based derivatisation agents in glycoscience, especially in sensitive mass spectrometry applications, is of great importance. They provide enhanced polarity and labelability to glycans, allowing for the monitoring and detection of glycans in complex samples. Additionally, ionic liquid based derivatisation agents can be used for the labelling of live cells, enabling the detection of cancer biomarkers and tuning of cell surface properties.
The functionalization of glycosides with ionic compounds such as ionic liquids provides enhanced polarity for the labelled glycans thanks to the presence of a permanent positive charge. The chemical derivatisation of glycans with ionic liquids constitutes an emerging strategy to boost the detection sensitivity in MS applications. This allows the straightforward monitoring and detection of the presence of labelled glycans in complex matrices and in those cases where very limited amounts of material were available such as in biological samples and chemoenzymatic reactions. The use of ionic liquid based derivatisation agents can be further exploited for the labelling of live cells via metabolic oligosaccharide engineering for the detection of cancer biomarkers and for the tuning of live cells-surface properties with implications in cancer prognosis and progression. In this mini-review we summarise the latest development of the ionic liquid based derivatisation agents in glycoscience focussing on their use for sensitive MS applications.
