Molecular Recognition of Carbohydrates: Evaluation of the Binding Properties of Pyrazole-based receptors and their Comparison with Imidazole- and Indole-based Systems

Abstract

The aim of the study was to evaluate the potential of pyrazole-based receptors in the complexation of carbohydrates. Representatives of a new series of acyclic pyrazole-based receptors were prepared and their binding properties toward selected mono- and disaccharides evaluated. The results of the binding studies were compared with those obtained for acyclic imidazole- and indole-based receptors. The first binding studies revealed di- vs monosaccharide binding preferences of the new receptors and showed that pyrazole units are useful building blocks for the construction of receptors with interesting binding preferences.
