Abstract
Bioactive copper complexes with oligosaccharides, pullulan or dextran, are the objective of the present study, because of their possible biomedical applications. The alkaline and acid hydrolysis of the Cu(II) complexes with reduced low-molar pullulan or dextran were carried out by conductometric method. The influence of ligand constitutions on the stability of the complexes was examined on the basis of ligand property. The complexes degradation during alkaline and acid hydrolysis were carried out in sodium hydroxide and hydrochloric acid solutions of 0.1, 0.5, and 1.0 mol dm−3, at different temperature (25, 40, and 60°C, respectively). According to the obtained results by the conductivity investigation during forced degradation studies, it could be concluded that the Cu(II) complexes show the small pharmaceutical stability to both hydrolysis.
