The tendency of increasing in p-AMPKα2 and p-AMPKβ1 was observed in the brain samples 60 minutes after decapitation of rats. This result suggested that AMPK was activated by neuronal ischemia. Infarction volumes in focal ischemia with rat model were decreased by AICAR, which is one of the activators of AMPK. However, AICAR exacerbated neuronal damage in gerbil forebrain ischemia, and the same exacerbation was observed in the administration of Compound C, one of the AMPK inhibitors.

大鼠断头后60 min脑组织中p-AMPKα2和p-AMPKβ1有升高趋势。提示AMPK在神经元缺血时被激活。AMPK激活剂AICAR可明显缩小大鼠局灶性脑缺血模型的梗死体积。然而，AICAR加重了沙鼠前脑缺血中的神经元损伤，并且在施用AMPK抑制剂之一的化合物C中观察到相同的加重。
