© 2018 Background: Stachybotrys microspora triprenyl phenol-7 (SMTP-7) has both potentials of thrombolytic and neuroprotective effects, but its detailed neuroprotective mechanisms in ischemic stroke are still unclear. Here, we assessed the neuroprotective effects of SMTP-7 for anti-inflammatory and antiapoptosis mechanisms after 60 minutes of transient middle cerebral artery occlusion (tMCAO) in mice. Methods: After 60 minutes of tMCAO, 0.9% NaCl, tissue-type plasminogen activator (tPA), SMTP-7 or tPA+SMTP-7 was intravenously administrated through subclavian vein just before the reperfusion, and these mice were examined at 24 hours after reperfusion. We histologically assessed the antineuroinflammatory effect of SMTP-7 on the expressive changes of inflammatory markers in ischemic mouse brains. Results: Compared with the vehicle and tPA groups, SMTP-7 treatment significantly improved clinical scores and decreased the infarct volume and the numbers of TNF-α, nuclear factor-κB (NF-κB), nucleotide oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3), and cleaved caspase-3-positive cells in the brain of mice at 24 hours after tMCAO but not p62-positive cells. However, tPA+SMTP-7 treatment did not show such effects. Conclusions: The present study suggested that SMTP-7 provides a therapeutic benefit for ischemic stroke mice through anti-inflammatory and antiapoptotic effects but not antiautophagic effect.
