A series of cyclic and acyclicnucleoside analogues derived from 3-hydroxy-4-pyridinone were synthesized using the Vorbruggen reaction. Iron chelation studies, and antiviral evaluation against a broad panel of viruses, were performed. The pK(a) value of ligand 25 and the stability constant of the corresponding iron(III) complex were compared to those of deferiprone. The pFe(3+) values were found to
