and evaluated glucoconjugated 8-hydroxyquinolines as copper ionophores activated by β-glucosidases. In order to further evaluate the crucial role of the sugar, we designed and synthesized a series of new galactoconjugates of 8-hydroxyquinolines and investigated their biological properties in comparison with the 8-hydroxyquinoline analogs. The effect of copper(II) ions on their biological activities was
