Summary
Researchers developed a new method using selenium-77 (77Se) Nuclear Magnetic Resonance (NMR) spectroscopy to monitor galectin-glycan interactions. This technique offers a novel way to study these important biological processes and screen potential inhibitors.
Area of Science:
- Biochemistry
- Chemical Biology
- Spectroscopy
Background:
- Galectins are key proteins involved in various biological processes.

- To explore the utility of selenium-77 (77Se) NMR spectroscopy for this purpose.
- To investigate the potential of doubly labeled glycosides (77Se and 19F) for advanced studies.
Main Methods:
- Synthesis of selenodigalactoside, a novel galectin ligand.
- Application of 2D 1H, 77Se CPMG-HSQBMC experiment with CPMG-INEPT long-range transfer.
- Utilizing 77Se NMR spectroscopy to monitor ligand binding.
Main Results:
- Selenodigalactoside was successfully prepared and confirmed as a bioactive galectin ligand.
- 77Se NMR spectroscopy was demonstrated as a practical method for monitoring galectin binding.
- The study established the potential of 77Se as a sensor for galectin binding studies.
Conclusions:
