[0017] Protective effect of Clik148 on focal ischemic brain injury in rats

[0018] Male SD rats were then divided into control group (sham operation group), model group, Clik148 high, medium and low dose groups (12.5, 25 and 50 nmol), 10 in each group. The rat model of permanent middle cerebral artery occlusion (MCAO) was established by suture method. Clik148 was injected into the cerebral ventricle before ischemia, with different concentrations and equal volumes. After 24 hours of ischemia, 5-point scoring method (the higher the score, the more obvious the neurological deficit) was used to measure the neurological function, and the effect of Clik148 on the volume of cerebral infarction was observed by TTC staining.

[0019] figure 1 Clik148 reduces the neurological symptom score of rats with cerebral ischemia, using a 5-point scoring method, the higher the score, the more obvious the neurological deficit (mean±SD, n=10). The intracerebroventricular injection of Clik148 bef...

Abstract

The invention discloses an application of a compound in preparing a medicine for treating a cerebrovascular disease. The structural formula of the compound is shown in the specification. The compound has a certain protective effect on cerebral ischemic injury, and can obviously improve neurological deficits caused by cerebral ischemia and reduces brain infarct volume.

Description

technical field [0001] The invention relates to a medicine for treating cerebrovascular diseases, in particular to a new application of compound Clik148. Background technique [0002] Cerebral stroke is a group of diseases whose main clinical manifestations are cerebral tissue ischemia and hemorrhagic injury symptoms, also known as stroke or cerebrovascular accident. The disease has an acute onset, high disability rate and high mortality rate, and is one of the most important diseases that endanger human health in the world today. Stroke is mainly divided into two categories: hemorrhagic stroke (cerebral hemorrhage or subarachnoid hemorrhage) and ischemic stroke (ischemic brain injury, including cerebral infarction and cerebral thrombosis). Stroke is the most common. [0003] At present, the clinical treatment of ischemic stroke mainly adopts drug therapy, including thrombolysis, vasodilator and anti-platelet aggregation. The above-mentioned drugs for the treatment of isc...
