Mild Toxic Effect of Dinitrosyl Iron Complexes During Inhalation of Syrian Hamsters in a "Nose-Only" Chamber

Using methods of general and biochemical blood analysis and histological analysis of the lungs, liver, heart and kidneys of Syrian hamsters, it was checked whether aerosol treatment of these animals with binuclear dinitrosyl iron complexes with glutathione, alone or followed by similar treatment of the same animals with diethyldithiocarbonate, as well as aerosol treatment of Syrian hamsters with dinitrosyl iron complexes with mercaptosuccinate, leads to negative, toxic effects at the level of the whole organism. The detected weak, reversible toxic effect in the form of nephrotoxicity of such treatment allows us to assert that such an effect, which ensures the suppression of COVID infection in these animals, is due to the selective in vivo action of dinitrosyl iron complexes and diethyldithiocarbonate on the SARS-CoV-2 virus, without affecting other tissues and organs of the animal.
