The interaction of Hoechst 33258 (H33258) and methylene blue (MB) compounds with bovine serum albumin (BSA) has been studied using the method of thermal denaturation. The obtained data showed that both ligands form complexes with BSA, moreover, MB binds to BSA stronger than H33258. Furthermore, H33258 destabilizes, while MB stabilizes the native structure of protein, leading to the decrease and increase of the denaturation temperature of BSA respectively.

The comparative study on interaction of bisbenzimidazole compound Hoechst 33258 and thiazine dye methylene blue (MB) with bovine serum albumin (BSA) was carried out by spectroscopic methods. Denaturation curves as well as absorption spectra and differential absorption spectra of protein-ligand complexes were obtained. Denaturation temperature of albumin complexes of BSA with Hoechst 33258 was shown to decrease with the growth of concentration ratio of ligand/protein, while for MB, vice versa, denaturation temperature increases. Changes in absorption spectra and differential absorption spectra of the complexes of ligands with albumin were revealed, which result from the binding of these DNA-specific ligands to protein. It is supposed that at the interaction of Hoechst 33258 with BSA some loosening of protein compact structure occurs due to the partial loss of helicity of α-structures, while for MB an increase of the protein compact structure takes place.
