The Neuroprotection of 1,2,4-Triazole Derivative by Inhibiting Inflammation and Protecting BBB Integrity in Acute Ischemic Stroke.

Background: The oxidative stress and neuroinflammation are important factors in acute ischemic stroke (AIS). Our former study showed the 1,2,4- triazole derivative (SYS18) had obviously neuroprotection by anti- oxidative stress on rat middle cerebral artery occlusion (MCAO) model.

Aim: In this study, we continue to investigate its neuroprotection by anti-inflammatory effects and protecting BBB integrity in AIS.

Synthesis of 1,3,5-triphenyl-1,2,4-triazole derivatives and their neuroprotection by anti-oxidative stress and anti-inflammation and protecting BBB.

Acute ischemic stroke (AIS) is a serious cardiovascular and cerebrovascular disease; Oxidative stress and neuroinflammation are important factors which destroy blood-brain barrier (BBB) in AIS. In the study, a series of 1,3,5-triphenyl-1,2,4-triazole derivatives were designed and synthesized; the optimal compound 9 was obtained by screening their anti-oxidant and anti-inflammatory effects; the neuroprotection effect of compound 9 was evaluated with a rat middle cerebral artery occlusion (MCAO) model. Subsequently, the mechanism of neuroprotection were explored via Western blot.
