• Functionalized Scaffold as a Tool for Systematic Investigation of β-Glucan Binding and Dectin-1 Activation ◦ Established the design and synthesis of a differentially protected scaffold which will be an invaluable tool for the investigation of β-glucan binding and Dectin-1 activation. ◦ Designed a scaffold that displays three β-glucan/reducing sugar molecules that mimics the particulate, multivalent and triple helical β-glucans. ◦ Synthesized a model trivalent sugar via a convergent synthetic approach based on the above design. ◦ Designed a common scaffold that allows the modular synthesis of multivalent sugars - a more practical and efficient synthetic strategy than the convergent synthesis. ◦ Synthesized the common scaffold starting from a commercially available dendrimer. ◦ Glycosylated the common scaffold with three reducing sugars. ◦ Monitored reaction progress using TLC. ◦ Purified and isolated intermediates and products using flash chromatography and GPC. ◦ Analyzed intermediates and products using LC-MS (QTOF) and NMR. • Trained new graduate students on techniques needed in their research projects.
