The spectral characteristics of the complexation between the RNA and ligands such as mannitol, sorbitol, and lactose, by using the methods of FTIR and FT-Raman spectroscopy and the mathematical model MCR-ALS, are studied. The complexation optimal ratios are determined in the RNA ligand system. In the RNA: mannitol mixture, the ratio is 3 : 1 with complexation about 100 %. In the case of a RNA: lactose mixture, the complexation decreases up to 30 %, and for a RNA: sorbitol mixture, up to 25 %. The results are in a good agreement with the antiviral activity of drugs on the cell culture. The optimal ratio and the better complexation in a RNA: mannitol mixture correspond to the best biological activity of this system. As a result of the replacement of mannitol by lactose in the RNA-ligand system, the biological activity of the preparation changes from antiviral preparation to immunomodulating and anti-inflammatory ones.
