Pharmacological Reports  
This work aimed to investigate the effect of lipoic acid (LA) on sulfane sulfur (S(*)) level and rhodanese activity in rat tissues. In vitro studies conduced so far have indicated that dihydrolipoic acid serves as an S(*) acceptor in the rhodanese-catalyzed S(*) transfer. This study revealed a significant increase in S(*) level and rhodanese activity in the heart, liver and kidney homogenates from rats that had previously been treated intraperitoneally with LA. It demonstrated for the first
more » ... in vivo that biological activity of lipoate might be connected with anaerobic cysteine metabolism to S(*) and with rhodanese activity.
