Neuroprotective Effect and Mechanism of Action of Tetramethylpyrazine Nitrone for Ischemic Stroke Therapy

Our previous studies demonstrated that the multifunctional agent TBN, a derivative of tetramethylpyrazine armed with a nitrone moiety, displayed high therapeutic efficacy in experimental ischemic stroke models. However, its molecular mechanisms of action underlying the neuroprotective effect need further exploration. In the present study, we found that TBN had significant activities scavenging free radicals such as ·OH, O null null null null...
