Abstract
The paper summarizes the results of our own research into the formation of molecular complexes of cyclodextrins with biologically active polyphenol compounds in water-organic solvents, chemical equilibria in the solutions of hydrazones and Schiff bases and their metal complexes in the solutions of DNA and proteins. It was found that an increase in the content of the non-aqueous component in the binary solvent leads to a decrease in the stability of molecular complexes of cyclodextrins with polyphenols and a decrease in the exothermicity of their formation reactions. It has been shown that metal complexes in an aqueous buffer solution containing also DNA or protein dissociate, and the released cation and free ligand bind to the biomolecule.
