Research ReportOsthole, a natural coumarin, improves neurobehavioral functions and reduces infarct volume and matrix metalloproteinase-9 activity after transient focal cerebral ischemia in rats
چکیده انگلیسی

Previously we demonstrated that Osthole, a natural coumarin, protects against focal cerebral ischemia/reperfusion-induced injury in rats. In the present study, the effects of Osthole on neurobehavioral functions, infarct volume and matrix metalloproteinase-9 (MMP-9) in a rat 2 h focal cerebral ischemia model were investigated. Osthole (100 mg/kg per dose) was administrated intraperitoneally 30 min before ischemic insult and immediately after reperfusion. Osthole treatment significantly reduced neurological deficit score and infarct volume by 38.5% and 33.8%, respectively, as compared with the untreated animals. Osthole reversed ischemia-reperfusion-induced increase in MMP-9 protein level/activity as evidenced by Western blotting and gelatin zymography. Taken together, these results for the first time demonstrate that Osthole reduces infarct volume, restores neurobehavioral functions and downregulates MMP-9 protein level/activity in ischemia/reperfused brain.

Research highlights►Osthole has neuroprotective effects against acute brain ischemia. ►Osthole reverses ischemia-reperfusion-induced increase in MMP-9 protein. ►Osthole inhibits MMP-9 activity in rat ischemia-reperfused brain.
