Supramolecular systems based on sodium alginate and viologen calyx[4]resorcinol for encapsulation of hydrophobic compounds

The work is devoted to the study of a supramolecular system based on viologen calix[4]resorcinol and sodium alginate in an aqueous medium using a set of physicochemical methods. It was established that sodium alginate and viologen calix[4]resorcinol form stable nanoparticles capable of encapsulating hydrophobic biologically active substances in the range of macrocycle:polymer concentration ratios from 1:2 to 1:10. The study of the cytotoxic properties of these nanoparticles in the presence of encapsulated substrates showed an increase in the selectivity of the action of quercetin and oleic acid against M-HeLa tumor cells by 2.47 and 1.14 times, respectively.
