A kind of gastrodine Glehnilae and preparation method thereof and application
Technical field
The present invention relates to field of medicine and chemical technology, particularly a kind of gastrodine Glehnilae and preparation method thereof and application.
Background technology
Sedative hypnotic English name is sedative-hypnotic, normally takes the favourable health in sedative hypnotic.Sedative hypnotic helps avoid insomnia infringement health and orthobiosis.Sedative hypnotic is the good medicine effectively helping for sleep and being effectively improved sleep.Sedative hypnotic is avoided that the insomnia serious harm to human body, and sedative hypnotic treatment insomnia disease, sleep quality is improved in sedative hypnotic.Most sedative hypnotic belong to healthy medicine, are not belonging to psychotropic substances.Obvious boundary, the difference only measured is not had between Hypnotics and sedatives.Low dose of hypnotic has sedation effect.Tranquilizer can make people quiet down.Tranquilizer is suitably used to be conducive to patient to recuperate.
The effect of central nervous system is had by the change of quantitative change to qualitative change by sedative hypnotic.Excessive excitement can be made to return to normally time low dose of, be called sedation;Can induce, deepen and extend sleep during middle dosage, be called syngignoscism;The tic that skeletal muscle is strong can be released during larger dose, be called anticonvulsant action;Consciousness anesthesia can be made time heavy dose of, but easily recover, be called anesthetic action;Functional activity can be made during toxic dose to stop not easily recovering, be called paralysis effect.The mechanism of action: blocking-up reticular formation of brain stem ascending activating system swashs, to corticocerebral, the effect of waking up, it is suppressed that dispersivity spreads, with drug dose size, it is suppressed that the shallow of degree calmness, hypnosis, convulsion, anesthesia and paralysis effect occurs deeply.Also it is believed that also have and directly suppress corticocerebral effect.Clinic is mainly used in calmness, hypnosis, convulsion, anxiety neurosis, hysteria, neurasthenia etc..
Along with increasingly sharpening of all sectors of society competition, neurasthenia and angioneurotic headache class disease remain problem to be solved.
Function of nervous system's sexual disorders that symptom is feature such as neurasthenia is owing to cerebral nerve activity is chronically at tense situation, causes that brain excitement and a group suppressing functional disorder and producing are easily excited with spirit, mental fatiguability, emotional instability.Normally behave as clinically: mental deficiency, tired mind, internal external stimulus sensitivity, anxious state of mind, shortage patience, insomnia, dreaminess, psychophysiological disorders, work efficiency drop etc., but exist without organic disease.
Current Most scholars thinks that Nervous and Mental Factors is to cause neurasthenic main cause.Every some factors that can cause lasting buck fever and long-term intrapsychic conflict, make strong and lasting in tension of neural activity process, exceed the tolerance limit of nervous system tension force, namely may occur in which neurasthenia syndrome, neurasthenia occurs.
Vascular headache is a kind of type the most common in outpatient service headache patient, because causing the reason of this kind of headache both to be from blood vessel, therefore is referred to as vascular headache.Vascular headache is divided into constitutional and the big class of Secondary cases two.Because of the headache that head vasomotor dysfunction causes, it is called constitutional vascular headache, also known as migraine, it it is a kind of functional headache, different manifestations according to headache, can be classified as again 5 kinds of main Types such as classical migraine, common migraine, cluster migraine, hemiplegia type migraine and ophthalmoplegic migraine;Another kind is to have the clear and definite headache caused by cerebrovascular disease (such as apoplexy, intracranial hematoma, cerebral vasculitis etc.), is called secondary headache.
Existing major part calmness, hypnosis, improve brain blood circulation medicine market and occupied by Western medicine, clinical application proves that, majority controls neurasthenic Western medicine, especially pain relieving class Western medicine, easily causing dependency, and Chinese medicine has the advantage of its uniqueness in treatment headache, form of Chinese drug can nurse one's health function on the whole, treatment headache, reaches treating both the principal and secondary aspects of a disease.
Gastrodine is the principle active component of Chinese medicine Rhizoma Gastrodiae, can regulate the dysequilibrium between cerebral cortex excitement and process of inhibition, have tranquilizing soporific, epilepsy, analgesic activity, be used for treating neurasthenia and neurasthenia syndrome;Blood vessel can be expanded again, improve brain blood circulation, increase vertebra one basilar arterial blood supply, improve vertebra one basilar artery insufficiency, treat vascular headache.Also there is now a lot of report to gastrodine structural modification, reach better effect with expectation.
Wearing is familiar with waits the chemical synthesis process at gastrodine and phenolic glycosides thereof to study [J]. Yunnan Institute for nationalities's journal (natural science edition), mention the similar phenol glucosides of multiple gastrodine in 2004,13 (2): 83-85:
Wherein A glycosyl part can be not only monosaccharide, and can be disaccharidase even trisaccharide etc., monosaccharide can be pentose, hexose or substituted monosaccharide, for instance: ribose, deoxyribose, xylose, arabinose, glucose, allose, mannose, galactose, glucosamine, lactose, maltose, cottonseed sugar etc..To glycoside unit, R1 can be C1~C6 alkylol or aldehyde, hydrogen atom, it is also possible at ortho position, a position, para-position.R2 can be C2~C6 alkyl, C1~C6 haloalkyl, C3~C6 cycloalkyl, aryl, hydrogen atom, amino, substituted-amino, halogen, hydroxyl, it is also possible at ortho position, a position, para-position.
Other many sections of documents and Li Huilan etc. at acegastrodine at the spasmolysis [J] to vascular smooth muscle. Acta Pharmaceutica Sinica, in 1986,21 (7): 539-541, mention another gastrodin derivative acegastrodine of gastrodine:
Wherein R is acetyl group.
Zhang Aiwu etc. are at Liang Qi Medical Colleges of the Inner Mongol journal, 2005,27 (2): 99-10 and 2007, two several gastrodine amino-acid ester schiff base compounds are proposed, it is desirable to filter out the gastrodin derivative of higher pharmacologically active in 29 (2): 110-112:
Wherein R is selected from serine ethyl ester base, methionine ethoxycarbonyl, ethycysteine base, phenylalanine ethyl ester base, glycine ethyl ester base, methyl methionine base, valine methyl ester base, phenyalanine methyl ester base, leucine methyl ester base, methyl lactamine base.
Gastrodine and acegastrodine have good clinical efficacy in improving and treating neurasthenia, neurasthenia syndrome and angioneurotic headache, but both to obtain good therapeutic effect, and patient medication every time must more than 100mg, comparatively inconvenience.
Ferulic acid (Ferulic acid) has antiplatelet aggregation, it is suppressed that platelet 5-HT discharges, it is suppressed that the generation of platelet thrombus element A2 (TXA2), strengthens the effects such as prostaglandin activity, analgesia, alleviating vascular spasm.There is bibliographical information ferulic acid to have the migrainous effect of radical cure, again because its toxicity is extremely low, be produce the base stock for treating the disease medicine such as cardiovascular and cerebrovascular disease and leukopenia.
There is presently no and gastrodine ferulic acid is combined into lipoid substance is used for improving and treating the open report of neurasthenia, neurasthenia syndrome and angioneurotic headache.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the present invention is just to provide a kind of gastrodine Glehnilae and preparation method thereof and application, can effectively solve to combine gastrodine ferulic acid and make gastrodine Glehnilae (also known as 4-hydroxymethyl phenyl-β-D-pyranglucoside esters derivative), and preparation improves and the medication problem for the treatment of neurasthenia, neurasthenia syndrome and angioneurotic headache.
