AbstractThe ammoniumion binding site of the enzyme glutaminase HisF inspired us to design guanidinium biscarboxylates as potential self-organized ionophores in molecular recognition. The syntheses of the title compounds based on aliphatic and aromatic building blocks, along with a general method for the preparation of δ-aminoethoxyacetic acids, are presented in this work. Investigation of the binding
A series of cyclic compounds with dimethyl-substituted 3-(aminoethoxy)propionic acid linkers have been prepared as potential β-turn mimics. The desired linkers were prepared from disubstituted pyrones, which were coupled with dipeptides and then subjected to macrocyclization using diethylcyanophosphonate to furnish cyclic compounds 1−5. Conformational analysis was carried out using NMR and X-ray crystallography
