Rutin protects hemorrhagic stroke development via supressing oxidative stress and inflammatory events in a zebrafish model
Eur J Pharmacol. 2022 Apr 22:174973. doi: 10.1016/j.ejphar.2022.174973. Online ahead of print.ABSTRACTIntracerebral haemorrhagic (ICH) stroke is a major cause of death and disability globally, with no proper treatment available so far. Rutin, a dietary flavonoid, has shown protection against cerebral ischemic stroke due to its antioxidant and anti-inflammatory attributes. However, the efficacy of rutin against ICH stroke remained unexplored. Therefore, in the current study, we investigated the effect of rutin in an ICH stroke zebrafish larva model. The larvae were exposed to atorvastatin (1.25 μM) in system water for indu...

Therapeutic targets of neuroprotection and neurorestoration in ischemic stroke: Applications for natural compounds from medicinal herbs
Biomed Pharmacother. 2022 Feb 12;148:112719. doi: 10.1016/j.biopha.2022.112719. Online ahead of print.ABSTRACTNeuroprotective and neurorestorative therapy represent two major drug intervention strategies for ischemic stroke. Multiple factors such as excitotoxicity, inflammation, angiogenesis, and neurogenesis are the main pathological processes that underlie acute and chronic ischemic brain injury. Furthermore, their intimate interactions mediate blood-brain barrier permeability, increase neurovascular unit structural damage as well as a hemorrhagic transformation during ischemic stroke. We aimed to review the current unde...

Pinocembrin attenuates hemorrhagic transformation after delayed t-PA treatment in thromboembolic stroke rats by regulating endogenous metabolites
In this study, we investigated the effect of pinocembrin on t-PA-induced HT and the potential biomarkers for HT after t-PA thrombolysis, thereby improving the prognosis of stroke. Electrocoagulation-induced thrombotic focal ischemic rats received intravenous infusion of t-PA (10 mg/kg) 6 h after ischemia. Administration of pinocembrin (10 mg/kg, iv) prior t-PA infusion significantly decreased the infarct volume, ameliorated t-PA-induced HT, and protected blood-brain barrier. Metabolomics analysis revealed that 5 differential metabolites in the cerebral cortex and 16 differential metabolites in serum involved in amino acid ...
