As major active ingredients of the traditional Chinese medicine motherwort, stachydrine and leonurine were found to have protective effects against cerebral ischemia. However, their bioavailability was low, and their efficacy was unsatisfactory, which limited their further application. To solve these problems, the conjugates based on the structures of stachydrine and leonurine were designed and synthesized. was found to have neuronal cell survival improvement, neuronal apoptosis restraining, activation of superoxide dismutase (SOD) activity, and inhibition of lactic dehydrogenase (LDH), reactive oxygen species (ROS), malondialdehyde (MDA) . , the infarction size was significantly reduced by in the middle cerebral artery occlusion rat model. could also activate protein kinase B (AKT)/glycogen synthase kinase 3β (GSK-3β) activity and promoted the expression of antiapoptoticprotein Bcl-2. On the other hand, the expression of the apoptosis-associated protein cleaved caspase-3 would be inhibited as well. Thus, as the neuroprotective agent has potential for the treatment of cerebral ischemic stroke.
