Description
Technical field
The present invention relates to class 3- alkyl -5,6- dioxy substituted phthalide compounds and its production and use, belong to doctor
Medicine technical field.
Background technology
Neuroinflamation and the pathogenesis of many nervous system diseases are closely related.These diseases are related to alzheimer
Disease, vascular dementia, Parkinson's, multiple sclerosis, ALS disease, diabetic neuropathy, and ischemic
Property cerebral apoplexy, hemorrhagic apoplexy, brain tissue impairment caused by wound etc..In addition, long-term or excessive inflammatory reaction is also possible to
Cause the mental illnesses such as depression and anxiety.Inflammation in brain is thin by the microglia activated and the astroglia of reactivity
What born of the same parents were induced.These cells are to play under the intrinsic immunocyte of intracerebral, physiological status to remove disease in central nervous system
The effect of the allogenic materials such as pathogenic microorganism and itself non-viable non-apoptotic cell, to maintain the stabilization of environment in nerve fiber;Under pathological state,
Spongiocyte sustained activation under the stimulation of various cause of disease materials, largely secretes a variety of inflammatory factors, such as tumor necrosis factor-alpha,
Interleukin -1β and interferon-γ etc., form pathology cascade reaction, cause neure damage even dead, induce or aggravate nerve
System lesion.In recent years research discovery, dangerous associated molecular pattern (DAMPs)-peroxide of Post stroke nerve cell release
Reduce enzyme family (Prxs) lose antioxidation activity, but can activating macrophage TLR2/TLR4 and mediate neuritic, be palsy
Central pathological physiological mechanism [the Nature Medicine.2011,17 of tissues following MCAO in rats damage:796;Nature
Medicine.2012,18:858]。
Another key factor of influence nervous function is the insufficient or unbalance of body substance and energy, especially
It is caused by cerebrovascular disease glycosyloxy supply lack and other material energy metabolisms it is unbalance.For example, nerve retrograde affection
Generation development and the Abnormality of Glycolipid Metabolism such as diabetes, obesity, hypercholesterolemia between there is obvious positive correlation.In hair
Sick early stage, utilization and brain blood flow of the brain to sugar is decreased obviously, and is caused patient's brain microcirculation blood flow state change, is limited
The compensatory of brain blood flow has been made, has made the deficiencies such as oxygen, the glucose of supply brain, the disorderly of nervous system material energy metabolism is ultimately caused
Disorderly, the nervous system disease is triggered.
Therefore, the inflammatory factor suppressed under pathological state excessively discharges, and the material energy metabolism for improving brain is to mitigate god
Important Intervention Strategy through damage.
China's natural pharmaceutical resources enrich, and applicating history is long, are the treasures of modern medicines research and development.To from biography
It is still the effective means for finding original new drug so far with structural modification that the natural products of system medicine, which carries out screening active ingredients,.Butylphthalide
(Butylphthalide, NBP) is that a kind of obtained phthalide compound is extracted from celery seed.Ligusticum wallichii, Radix Angelicae Sinensis, Jehol Ligusticum Rhizome etc. also contain
There is the composition.The butylphthalide of natural origin is with optically active levo form.Its artificial synthesized racemic modification is made at present
For the original new chemical entities medicine of China be used clinically for gently, the treatment of moderate acute ischemic cerebral apoplexy.Research shows,
Butylphthalide has significant neuroprotection, can increase ischemic region cerebral blood flow (CBF) and the microcirculation of reconstruct ischemic region, protective wire
Mitochondria function, suppress platelet aggregation and thrombosis, improve the energetic supersession after global cerebral ischemia, mitigate nervous function damage
Degree, is related to multiple links of cerebral ischemia pathology, has significant therapeutic effect to cerebral apoplexy.In addition, butylphthalide is to A Er
DPN caused by Zi Haimo diseases, vascular dementia, Parkinson's, diabetes, memory disorders, cerebral apoplexy, traumatic brain injury,
Many the nervous system diseases such as epilepsy, depression, which also have, to have some improvement.
But there is also some shortcomings for butylphthalide.For example, the compound is higher boiling grease, its polishing purification is to life
The requirement for producing equipment is high;Unstable in vivo, metabolite clearance is fast;It is grease under normal temperature, is not easy to prepare oral solid formulation,
Only soft capsule is for being administered orally at present;With special odor, discomfort may be caused.
Research finds that in blood plasma ring closure reaction generation butyl benzene can quickly occur for 2- (Alpha-hydroxy amyl group) benzoic acid and its salt
Phthalein.Butylphthalide and alkali reaction are changed into pro-drug, i.e. 2- (Alpha-hydroxy amyl group) benzoic acid and its salt, butyl can be improved
The defect of phthalide itself poorly water-soluble.But, 2- (Alpha-hydroxy amyl group) benzoic acid and its salt, including the nothing such as potassium, sodium, calcium, magnesium, zinc
The organic amine salt such as machine salt and benzylamine, morpholine, diethylamine, often have that crystallinity is poor, hygroscopicity strong, easily decompose, it is acid or in
The shortcomings of unstable under property environment.In addition, the sylvite of 2- (Alpha-hydroxy amyl group) benzoic acid or the aqueous solution of sodium salt are (usual in alkalescence
pH>9), there is certain physiological stimulation.
The present inventor in view of the shortcomings of the prior art, has designed and synthesized a series of phthalide compound, therefrom screened
Active stronger, security more preferably, patent medicine property more preferably phthalide compound.

Model groups).After Reperfu- sion 72 hours, neurogenic behavior rating is carried out, animal is put to death and takes brain Nissl dyeing detection hippocampus CA1s
The survived neuronal cell number at same position, is as a result shown in Fig. 2 in area and corpus straitum CPu brain areas.
Compared with sham-operation group (Sham groups), mouse bilateral common carotid arteries it is of short duration ligation and cause cerebral ischemia, cause model
Group (Model groups) animal nerve behavior disorder, neuron loss and astroglia excessive activation;And given after cerebral ischemia reperfusion
Different phthalide compounds are given to treat, C-1, C-2, C-3 show stronger neuroprotection, can not only improve the low filling shape of brain
The mouse neurobehavioral function of postoperative 24 hours, 48 hours and 72 hours under state, moreover it is possible to increase the god of hippocampus and corpus straitum brain area
Through first cell number, and effect is better than NBP.
Embodiment 8To the acute toxicity of mouse
SPF grades of ICR mouse, 18~20g, male and female half and half, after adaptability is fed 3 days, fasting is weighed random point for 12 hours
Group:Solvent group and administration group (C-1, C-2, C-3).Each test-compound is matched somebody with somebody with 0.5% carboxymethylcellulose sodium solution before use
Suspension decoction processed, given low is 1.0g/20ml/kg;Solvent group gavage 20ml/kg blank solvent.After administration, 48 hours
Interior animal single cage is raised, 2 hours Continuous Observations after medicine, and ditto the weight of animals is weighed within 7 days, 14 days after medicine.
Under the experiment condition, C-1, C-2, C-3 given low 1.0g/kg are showed no any adverse reaction to ICR mouse;
In 14 day observation period, the mouse weight of each administration group and solvent group, which increases, has no difference, without animal dead.As a result show, C-
1st, the safe dose that mouse stomach is administered by C-2, C-3 is all higher than 1.0g/kg.
