Improved binding affinity and interesting selectivities of aminopyrimidine-bearing carbohydrate receptors in comparison with their aminopyridine analogues
Molecular Recognition of Carbohydrates with Artificial Receptors: Mimicking the Binding Motifs Found in the Crystal Structures of Protein−Carbohydrate Complexes
摘要:
The binding motifs found in the crystal structures of protein-carbohydrate complexes have been successfully mimicked with simple acyclic pyridine- and pyrimidine-based receptors. A full discussion of the recognition motifs observed in the crystal structures of complexes of receptors 1 and 3 with glucopyranosides 4a and 4b is provided. A remarkable similarity of these motifs to those observed in the crystal structures of sugar-binding proteins and those found by molecular modeling is shown. In addition, the recognition properties of the new pyrimidine receptor 3 toward monosaccharides 4-6 are described. This molecule has been established as a highly effective receptor for beta-glucopyranosides.
The field of the invention relates to the use of carbohydrate binding compounds as a medicine, their use to treat or prevent viral infections, their use to manufacture a medicine to treat or prevent viral infections and their use in a vaccination strategy. The present invention relates to the use of said compounds to manufacture a medicine to treat or prevent viral infections of subject, more in particular infections with viruses having glycosilated envelope proteins such as Retroviridae (i.e., Lentivirinae), like HIV (human immunodeficiency virus), Flaviviridae, like HCV (hepatitis C virus), Hepadnaviridae, like HBV (hepatitis B virus), Coronaviridae, like SARS corona virus, and Orthomyxoviridae, like influenza A, B, or C.
