Abstract
Reactive oxygen species (ROS) formation has been found to induce the brain damage following stroke-like events. The aim of the present study was to investigate the effect of Stachybotrys microspora triprenyl phenol-7 (SMTP-7) on the generation of ROS in ischemia-induced cerebral infarction model and in vitro lipid peroxidation. We used immunohistochemistry and real-time reverse-transcription PCR for ex vivo evaluation and thiobarbituric acid-reactive substance reagent assay for in vitro evaluation. We demonstrated that SMTP-7 did not induce enhancement of 4-hydroxynonenal or neutrophil cytosolic factor 2 like t-PA administration at 3 h after ischemia ex vivo and reduce lipid peroxidation in vitro. This compound is the first low molecular weight compound with triplet activities of thrombolytic, anti-inflammatory, and antioxidant activities. We theorized that SMTP-7 is among the pharmacological agents that reduce ROS formation and have been found to limit the extent of brain damage following stroke-like events.
