Abstract

The invention relates to an application of a sphingosine kinase 1 inhibitor in preparation of a medicine for preventing and/or treating a secondary brain injury after cerebral hemorrhage, and belongsto the technical field of medical technologies. The invention provides the application of the sphingosine kinase 1 inhibitor in the preparation of the medicine for preventing and/or treating the secondary brain injury after cerebral hemorrhage. An existing sphingosine kinase 1 inhibitor 5C is applied to the preparation of the medicine for preventing and/or treating the secondary brain injury aftercerebral hemorrhage. A new source is provided for the preparation of the medicine for preventing and/or treating the secondary brain injury after cerebral hemorrhage, and meanwhile, a new medicinal value of the sphingosine kinase 1 inhibitor 5C is explored. The technology is funded by Guangxi Science and Technology Base and Talent Special Fund (Guike AD18281013) and Guangxi Natural Science Foundation General Program (2020GXNSFAA259036) Guangxi Natural Science Foundation of Youth Fund (2018GXNSFBA138046). The structural formula of the sphingosine kinase 1 inhibitor is shown in the specification.

Description

technical field [0001] The invention relates to the application of a sphingosine kinase 1 inhibitor in the preparation of a drug for preventing and / or treating secondary brain injury after cerebral hemorrhage, and belongs to the technical field of medicine. Background technique [0002] Cerebral hemorrhage is a sudden-onset blood circulation disorder, clinically manifested as transient or permanent dysfunction, and is an important type of stroke. Cerebral hemorrhage deaths in the Chinese population account for about 61.7% of cerebrovascular disease deaths, and its high morbidity and mortality have become the leading cause of death for Chinese people. At present, it is believed that secondary brain injury after cerebral hemorrhage is the main injury mechanism, including neurotoxicity of red blood cell degradation products, thrombin, inflammation, edema, blood-brain barrier damage, etc. The above factors lead to cell death such as apoptosis, necrosis, and autophagy. cause irr...
