N-Glycoconjugates: Selective colorimetric chemosensors for aspartic acid and cysteine

Selective recognition of naturally occurring amino acids have been explored using five glycopeptide-based receptors with the help of UV-visible and H-1 NMR spectroscopy, while structures of two glycopeptides have been established via single crystal X-ray diffraction studies. The receptors containing alanine, valine, isoleucine and methionine moieties interact selectively with aspartic acid, while phenylalanine derivative with cysteine. (C) 2021 Elsevier B.V.

Automated summary

This study explores the selective recognition of naturally occurring amino acids using five glycopeptide-based receptors. The receptors containing specific amino acid moieties interact selectively with certain amino acids, as confirmed by UV-visible and H-1 NMR spectroscopy, and single crystal X-ray diffraction studies.
