Description
Technical Field
The invention relates to the fields of biological medicine and chemistry, in particular to a butylphthalide derivative and application thereof in preparing a medicament for protecting nerve cells.
Background
Butylphthalide is a small molecular protein extracted from celery or celery seeds. This protein is small and can easily pass through the blood-brain barrier to exert its effect on brain cells. In 1978, the institute of medicine of Chinese academy of medicine sciences separated levo-butylphthalide from cress seeds. Butylphthalide is first chemically synthesized in 1980, the initial research direction of the butylphthalide is anti-epilepsy, but the butylphthalide has larger potential safety hazard due to the fact that the therapeutic dose for resisting epilepsy is close to the toxic dose, and the research is accordingly stranded.
The butylphthalide is mainly used for treating mild and moderate acute ischemic stroke, can reduce the concentration of calcium ions in cells, inhibit the release of glutamic acid, reduce the generation of arachidonic acid, clear oxygen free radicals, improve the activity of oxidase and the like, and acts on a plurality of pathological links of cerebral ischemia. Meanwhile, the composition has a strong anti-cerebral ischemia effect, can obviously improve microcirculation and blood flow of cerebral ischemia areas, increase the number of capillaries in the cerebral ischemia areas, relieve cerebral edema, reduce the volume of cerebral infarction, improve brain energy metabolism and also has a certain effect of inhibiting thrombus. The earlier in onset, the better the prognosis for the patient. The butylbenzene peptide can take effect within 24 hours physiologically, but if the patient needs to have obvious improvement of symptoms clinically, at least 5-7 days are needed.
All the medicines have positive and side effects, and the butylphthalide has the same side effect as the positive effect, and can activate brain cells and promote the metabolism of the brain cells. When the brain cells are improperly activated after activation, hallucinations and epilepsy may occur. In addition, all drugs are metabolized by liver and kidney functions, and there may be some patients with elevated transaminase. Since it increases blood flow in brain and increases proliferation of blood vessels, it can produce blood seepage at cerebral infarction area in case of some special cerebral infarction or few cerebral infarction.
