It has been proposed that free radicals, reactive oxygen species (ROS) and reactive nitrogen species play a critical role in gastric mucosal damage. It is well known that the exposure of gastric mucosa to damaging factors such as stress and nonsteroidal anti-inflammatory drugs produces acute ulcers that are mainly mediated by ROS. The aim of the present study was to investigate the gastroprotective properties of bis(1-hydroxy-2,2,6,6-tetramethyl-4-piperidinyl)decandioate (IAC), a novel nonpeptidyl low-molecular-weight radical scavenger, in two different models of gastric ulcer in rats caused by ROS. IAC was orally administered at the doses of 50 and 100 mg/kg before gastric ulceration induced by indomethacin and water immersion and restraint stress. The number and severity of gastric lesions, following macroscopic inspection of the mucosa, were evaluated and expressed as an ulcer score. Oral administration of IAC dosed at 50 and 100 mg/kg was able to significantly prevent gastric ulceration induced by indomethacin and by stress. The gastroprotective effect of IAC on gastric mucosa could be attributed to its intrinsic antioxidant activity, suggesting it as a novel antiulcer agent. Copyright (C) 2011 S. Karger AG, Basel
