Nakamura Group, Research Outline

Natural receptor proteins can bind substrates selectively at the pocket surrounded by multiple amino acid residues. Relatively weak intermolecular interactions, such as hydrogen bonds, are synergistically exerted during the recognition events. Meanwhile, it was difficult for synthetic receptors to achieve precise molecular binding by arranging various interaction moieties in an unsymmetrical manner.
 Our group develops novel macrocyclic receptors with precise recognition properties based on two concepts, that is, (A) assembly of metal coordination sites, and (B) desymmetrization of the molecular components
