Investigations of bioactive copper complexes are of great interest for the pharmaceutical industry from the aspect of therapy of hypochromic microcitary anemia and hypocupremia. The structure of bioactive copper complexes with oligosaccharides has not yet been explained in details despite a number of studies. This work represents further development in the research of the complex structure and pharmacobiological activity of the copper complexes. Different copper complexes with dextran and pullulan oligosaccharides, as well as reduced derivatives, have been analyzed by IR spectroscopy. Characterization of the complexes has been performed by using modern spectroscopic techniques: RT-FTIR, LNT-FTIR, D2O-FTIR, ATR-FTIR and FTIR microspectroscopy. Results of FTIR microspectroscopic investigations show that the structural form of complexes and copper content depend considerably on constitution and ligands conformation, degree of crystallinity, polymerization, polydispersity, and linearity of macromolecules. Also, stability of the synthesized complexes, as well as their pharmacological effect, depend on these parameters. Based on IR testing results, structures of the synthesized Cu(II) complexes with polysaccharides were confirmed.
