Researchers created dynamic multivalent lactosides by threading lactose-appended cyclodextrin derivatives onto polymers. This novel method efficiently forms compounds for lectin binding, observable via NMR spectroscopy.

Area of Science:

  • Supramolecular Chemistry
  • Carbohydrate Chemistry
  • Polymer Science

Background:

  • Lectins play crucial roles in biological processes, making them important targets for drug development.
  • Dynamic multivalent interactions are key for specific and high-affinity molecular recognition.

Purpose of the Study:

  • To synthesize novel dynamic multivalent lactosides for lectin binding.
  • To develop an efficient method for creating these supramolecular structures in aqueous solution.

Main Methods:

  • Synthesis of lactose-appended cyclodextrin derivatives.
  • Threading of these derivatives onto hydrophobic polymers in aqueous media.
  • Characterization using one- and two-dimensional NMR spectroscopies.
