(E)-2-benzylidene-4-phenyl-1,3-diselenole has antioxidant and hepatoprotective properties against oxidative damage induced by 2-nitropropane in rats.

Abstract
The in vitro effect of (E)-2-benzylidene-4-phenyl-1,3-diselenole (BPD) was evaluated through iron/EDTA-induced thiobarbituric acid reactive species (TBARS) and reactive species (RS) determinations as well as of the scavenging 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical quantification. BPD at the concentrations of 10 and 50 μΜ decreased RS and TBARS levels, respectively. The antioxidant activity was not related to the scavenging DPPH radical mechanism. A second objective of this study was to investigate the hepatoprotective action of BPD, administered by oral route, against oxidative damage induced by 2-nitropropane (2-NP) (100 mg/kg of body weight) in liver of rats. At the dose of 50 mg/kg, BPD protected against the increase in aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) activities induced by 2-NP. BPD (10 and 50 mg/kg) protected against the increase in TBARS levels and alkaline phosphatase (ALP) activity. Sections of liver from 2-NP-exposed rats presented intense infiltration of inflammatory cells and loss of cellular architecture. BPD (10 and 50 mg/kg) attenuated 2-NP-induced hepatic histological alterations. The inhibition of δ-aminolevulinic dehydratase (δ-ALA-D), glutathione peroxidase (GPx), glutathione reductase (GR), and glutathione S-transferase (GST) activities and the decreased GSH levels caused by 2-NP were protected by BPD (50 mg/kg). Catalase activity and ascorbic acid levels were not altered by 2-NP. These results demonstrated the antioxidant and hepatoprotective effects of BPD in liver of rats.
