Abstract

The invention discloses application of sorafenib shown in a formula (I) to the preparation of a medicinal composition for treating cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH). Animal experiments prove that BAY 43-9006 has the effect of obviously inhibiting the CVS after the SAH, and can be used for improving the CVS after the SAH.

Description

technical field [0001] The invention belongs to the technical field of new uses of medicines, and specifically relates to the application of sorafenib in the treatment of cerebral vasospasm after aneurysmal spontaneous subarachnoid hemorrhage. Background technique [0002] The annual incidence of spontaneous subarachnoid hemorrhage (SAH) is about 6-16 / 100,000 people, accounting for about 6-8% of the total incidence of stroke. Intracranial aneurysm rupture is the main cause of spontaneous SAH. reason. Cerebral vasospasm (CVS) is a common potentially disabling and fatal complication after aneurysmal SAH. For decades, many scholars have conducted a lot of basic and clinical research on the pathological process of CVS formation, but its exact mechanism is still not completely clear. Nuclear factor κB (Nuclear factor-κB, NF-κB) plays an important regulatory role in inflammatory responses, and activated Raf-1 kinase promotes the activation of NF-κB by promoting the degradation o...
