Diphenyl Diselenide Reduces Oxidative Stress and Toxicity Caused by HSV‐2 Infection in Mice

Abstract

Herpes simplex viruses can cause uncommon systemic complications as acute liver failure (ALT) or urinary tract dysfunctions. Diphenyl diselenide, (PhSe) , a classical studied organic selenium compound, has a novel antiviral action against HSV-2 infection and well-known antioxidant and anti-inflammatory properties. This study aimed to investigate if (PhSe) reduces oxidative stress and systemic toxicity caused by HSV-2 infection in mice. Adult BALB/c mice were pre-treated with (PhSe) (5 mg kg /day, intragastric, i.g.) during 5 days; at day 6 mice were infected with HSV-2 (10 μl-10 PFU/mL ) and post-treated with (PhSe) for more 5 days. At day 11, they were killed and samples of liver and kidney were obtained to determine: reactive species (RS); malondialdehyde (MDA), and non-protein thiols (NPSH) levels; the activities of antioxidant enzymes, superoxide dismutase (SOD), and catalase (CAT). The activities of adenosine deaminase (ADA), Na /K -ATPase (liver and kidney); alanine aminotransferase (ALT), aspartate aminotransferase (AST), and the levels of urea (plasma) were determined as markers of hepatic and renal toxicity. The results revealed that (PhSe) treatment was effective against the increase of renal and hepatic oxidative stress in infected mice and also normalized hepatic and renal ADA activity. It recovered the activity of Na /K - and was not effective against the increase in urea levels in infected mice. Different from (PhSe) , acyclovir (positive control), caused an increase in ADA activity and a decrease in hepatic CAT activity. Considering the interest of alternative therapies to treat HSV-2 infections and secondary complications, (PhSe) become a notable candidate. J. Cell.

Activation of SOD-3 is involved in the antioxidant effect of a new class of β-aryl-chalcogenium azide compounds in Caenorhabditis elegans

“…In fact, over-expression and/or overactivation of SOD-3 are required for the induction of pro-longevity response after mild oxidative injury (Salgueiro et al 2017). In agreement with our results, it has been demonstrated that the treatment with organochalcogen compounds present an antioxidant action in the liver of rats by increasing the activity of SOD-3 and decreasing the generation of reactive species in different disease models (Quines et al 2017, Sartori et al 2017.…”

Combined Acylselenourea–Diselenide Structures: New Potent and Selective Antitumoral Agents as Autophagy Activators

“…Among the chemical entities containing selenium that have been identified, the chemical form of diselenide stands out as an appealing skeleton for development of new anticancer agents . In particular, diphenyl diselenide (PhSe) 2 has been widely studied and has proven activity as oxidative stress protector, , presenting also cytotoxic activity . In this line of investigation, our research group has explored this chemical entity and the most potent antitumoral structures synthesized in our group containing the diphenyldiselenide moiety corresponds to bis­(4-aminophenyl)­diselenide structure .…”

Antioxidant activity of novel selena-diazole derivative against oxidative stress induced by dipyrone in female rats

“…The GPX and SOD plasma levels increased significantly in Se-supplemented-diet to diabetic rats for one month (Ghaffari et al, 2011). Another study demonstrates that diphenyl diselenide (PhSe) active in contradiction of increased oxidative stress in kidney and liver (Sartori et al, 2017). Pre-treatment with diphenylmethyl selenocyanate found to be the most powerful SOD and CAT inducer (Jayanta Kumar Dasa et al, 2013).…”
