Antioxidant Activity of Silver-containing Bionanocompositions Based on Humic Substances in Cell Culture
Introduction. Silver nanoparticles are promising agents for suppressing resistant strains of microorganisms and accelerating the purulent wounds healing. Oxidative stress disrupts normal wound healing processes, which leads to the formation of chronic non-healing wounds. Therefore, the determination...

| description | Introduction. Silver nanoparticles are promising agents for suppressing resistant strains of microorganisms and accelerating the purulent wounds healing. Oxidative stress disrupts normal wound healing processes, which leads to the formation of chronic non-healing wounds. Therefore, the determination of the ability of new wound healing agents to decrease the production of reactive oxygen species is a relevant task.Aim. The aim of the current study was to investigate the effect of silver-containing bionanocompositions based on humic substances on the basal and tert-butyl hydroperoxide-stimulated production of reactive oxygen species at the normal fibroblasts 3T3-L1 cell culture in vitro.Materials and methods. The study was carried out on 7 samples of initial humic substances and biomaterials with silver nanoparticles synthesized in the Laboratory of Natural Humic Systems, Faculty of Chemistry, Moscow State University named after M. V. Lomonosov. The intracellular production of reactive oxygen species was assessed using a 2,7-dichlorodihydrofluorescein diacetate fluorescent probe. Cells were cultured with samples for 24 h; tret-butyl hydroperoxide was used to stimulate the production of reactive oxygen species. Detection was performed fluorometrically using a microplate reader.Results and discussion. The most pronounced antioxidant activity was demonstrated by three samples of biomaterials with silver nanoparticles ultradispersed in humic substances matrices (CHS-AgNPs, CHP-AgNPs and CHE-AgNPs), which allows us to consider them as the most promising pharmaceutical agents for the treatment of purulent-inflammatory processes. The most probable mechanism of the high antioxidant activity of the studied biomaterials in relation to intracellular reactive oxygen species is the intrinsic activity of humic substances to bind reactive oxygen species, while silver nanoparticles in biomaterials catalyze the reduction processes of their interaction with reactive oxygen species.Conclusion. For the studied samples of biomaterials with silver nanoparticles ultradispersed in matrices of humic substances pronounced antioxidant activity was shown. Together with antibacterial properties, it makes it possible to consider them as potential agents for purulent wounds healing accelerating. |
