Definitions
- the present invention relates to cerebral infarction treatment or cerebral infarction comprising N- (3 black mouth 4 monorephorin 1 4-inore) phenol-N, 1 hydroxymidformamide and a thrombolytic agent. It is related with the pharmaceutical excellent in the improvement of the dysfunction caused by this, or the neurological deficit symptom.
- Cerebral infarction refers to cerebral dysfunction caused by ischemic necrosis in the brain, and is a disease requiring emergency treatment. Cerebral infarction is classified into thrombotic, embolic, and hemodynamic in terms of mechanism of action, and from clinical aspects, it is classified as atherothrombotic cerebral infarction, cardiogenic cerebral embolism, Lacna infarction, etc. Classified (see Non-Patent Document 1).
- Ischemia occurs when cerebrovascular lesions such as arteriosclerosis or the local cerebral blood flow is blocked by cardiogenic thrombus, and neuronal cell death due to energy depletion is caused at the ischemic central site.
- the blood flow through the accessory blood circulation remains around the ischemic center, and the nerve cells are alive but not functioning electrophysiologically.
- this treatment is applied, this part of the nerve cell will die in the future, and pathologically, it will be a failure of cerebral infarction, and clinically, it will be impaired as a malfunction. Therefore, if the function of nerve cells in this part can be restored as early as possible, dysfunction can be treated.
- This reversible incomplete ischemic region is called Benambra.
- the purpose of treatment for the acute phase of cerebral infarction is to restore the function of neurons in this penumbra region, the outcome of which depends on the extent of ischemia and its duration. In other words, how quickly the blood flow is resumed in the penumbra area determines the outcome. It is said that neurons in this penumbra region can survive for 3 to 6 hours after onset.
- the allowable time during which the nerve cells in the Benampura region can recover their function by treatment is called the treatable time.
- rt-PA recombinant human tissue plasminogen activator
- Non-Patent Document 2 rt PA is administered to patients within 3 hours of onset, and if no intracerebral hemorrhage is observed, first rapidly infuse 10% of the total dose (0.9 mg Zkg), and the rest for 1 hour. Continue intravenous infusion over the above.
- 20-Hydroxyeico satetraenoic acid (20—HETE) is a product that is metabolized from arachidonic acid by cytochrome P450 4A or 4F (CYP), a 20-HETE-producing enzyme, and has a vasoconstrictive action (non-patented) Reference 3).
- 20— HETE is also produced in the cerebral blood vessels and has a powerful cerebral vasoconstriction action based on Ca 2+ — activated K + — channel inhibition, thus regulating cerebral blood flow under physiological conditions It plays an important role as a factor. It has also been shown that it is also involved in cerebral vasoconstriction after subarachnoid hemorrhage (see Non-Patent Document 4).
- N— (3 Black mouth— 4 Morpholine— 4—yl) phenol—N, —Hydroxyimidoformad (N— (3— Chloro— 4— morphlin— 4— yl) phenyl— N — Hydroxyimidofrmamide) is a selective and potent inhibitor of 20-HETE producing enzyme, which is compound 302 in Patent Document 1, and is represented by the following chemical formula.
- N— (3-Chromosome— 4 Morpholine— 4—yl) phenol— N′-hydroxyimidoformamide exhibits a cerebral infarct volume-reducing action in a transient middle cerebral artery occlusion model in rats ( Non-special (Ref. In this model, the treatment time is 4 hours after the ischemic load, and the neurological deficit symptoms (sensory motor function, balance sensation, coordinated motor function) 7 days after the onset of symptoms are improved (Non-patent Document 6). reference). Based on the above, N- (3-chloro-4 morpholine-4yl) ferro-N, monohydroxyimidoformamide can improve dysfunction due to cerebral infarction when administered in the acute phase of cerebral infarction.
- N- (3-Chrotine 1- 4-morpholine 1- 4-yl) file N and 1-hydroxyimide formamide were administered in combination. Furthermore, it is expected to enhance the therapeutic effect on cerebral infarction.
