Abstract
Description
Technical Field
[0001] The present invention relates to use of a composition in preparing a medicine for treating migraine in patients. Background Art
[0002] Migraine is a common, recurrent headache disorder characterized by throbbing, severe headache on one or both sides, often accompanied by nausea, vomiting, and hypersensitivity to sound and light stimulation. Common types include migraine without aura, migraine with aura, and chronic migraine. The causes of migraine may be related to genetics, endocrine metabolism, environmental factors, mental factors, etc., and often have a genetic background. Female patients are 2-3 times more likely to develop the disease in adolescence, and a small number may develop the disease in childhood. In terms of symptoms, the typical manifestation of migraine is severe headache, which may be pain on one side of the head and migrate to the other side, and may also be sensitive to light, noise, and smell. Common associated symptoms include nausea, vomiting, stomach discomfort, abdominal pain, feeling very hot or cold, pale skin color, etc.
[0003] In terms of treatment, migraine cannot be cured at present. Most treatments aim to reduce headache attacks, relieve associated symptoms, and prevent headache recurrence. There are drug treatments and non-drug treatments. Drug treatments are divided into attack treatment and preventive treatment. Clinical drugs include opioid analgesics, non-steroidal analgesics, monoclonal antibodies, etc. However, they cannot produce satisfactory therapeutic effects, and some drugs have very serious side effects. Frequent use will cause patients to have other clinical symptoms. Therefore, the current drug pain relief for migraine treatment has not been able to truly meet the clinical needs of patients, so migraine has always been a disease that seriously affects the quality of human life.
[0004] The causes of migraine are generally believed to include genetics, endocrine metabolism, environmental factors, and psychological factors. Further studies have found that migraine is related to pathological factors such as increased serum nitric oxide (NO) concentrations. This is because increased serum nitric oxide (NO) concentrations can lead to dilation of cerebral blood vessels, leading to migraines. At the same time, nitric oxide can cause pain hypersensitivity and inflammatory reactions, which in turn aggravate the severity of migraines. [1-5] Treatments such as lowering nitric oxide (NO) levels are effective in improving the severity of migraines.
[0005] Currently, migraine treatment options mainly include acute and preventive treatments. With the exploration of signal pathways related to migraine attacks, more and more treatment methods will be developed for migraine treatment. Downregulating nitric oxide (NO) concentration can be used as an effective method for migraine treatment. Summary of the invention
[0006] The present invention relates to the use of a composition in the preparation of a drug for treating migraine in patients, characterized in that the composition comprises cobra cardiotoxin (CDX), and the pharmaceutical composition of the present invention has an analgesic effect on a rat nitroglycerin type migraine test model. Its mechanism may be related to blocking or down-regulating the signaling pathway of nitric oxide (NO). Cobra cardiotoxin can simultaneously treat and prevent the occurrence of migraine, and has no serious toxic side effects in animal experiments, so it is a drug candidate worthy of expectation.
[0007] Cobra cardiotoxins all have the commonality of a three-finger protein structure in terms of functional structure. Not only do they have the same spatial structure, but the amino acid sequences of their mature proteins are also highly homologous. Therefore, the commonality of cardiotoxins in functional structure enables them to achieve consistent function of regulating the signaling pathway of nitric oxide (NO), which also makes the cardiotoxins consistent in treating the rat nitroglycerin-type migraine model.
[0008] The amino acid sequences of the mature proteins of cobra cardiotoxins have the following common features:
