Description

A kind of azaspiro ketone pharmaceutical composition and preparation method thereof
Technical field
The present invention relates to a kind of azaspiro ketone pharmaceutical composition and preparation method thereof.
Background technology
Tandospirone belongs to azaspiro ketone medicine, and [4 [(2- is phonetic by 4- by entitled (3a α, 4 β, 7 β, the 7a α)-hexahydro -2- of chemistry Piperidinyl) -1- (piperazinyl)-butyl] -1,3 (2H)-diketone of -4,7- methylene -1H- iso-indoles.It is a kind of 5-hydroxytryptamine receptor Activator, belongs to the 3rd generation anxiolytic, is mainly used in the disease for treating anxiety or other companion's anxiety states.Tandospirone can Height selectively with integrated distribution emotion maincenter hippocampus, in every, the cerebral limbic system such as interpeduncular nucleus, amygdaloid nucleus and seam gland The 5-HT of core1AAcceptor is combined, exciting 5-HT1AAutoreceptor, plays angst resistance effect.Tandospirone can also play one simultaneously Fixed antidepressant effect.
Compared to it with analog derivative buspirone, Tandospirone has higher selective angst resistance effect, this work With close with diazepam, but the toxic side effect in terms of nervimotion Sexual dysfunction and drug abuse is smaller than diazepam. Due to the specificity of mechanism of action, when Tandospirone is used clinically for treatment anxiety disorder, with drug safety height, side effect Less, sedative-hypnotic effect is weak, without relaxed muscle effect, no dependence and drug withdrawal give up after phenomenon, prolonged application in vivo without The advantages of accumulation.Proved through long-term clinical practice, Tandospirone is to the anxiety state caused by various neurosises, light modest depression Disease, and a variety of physical diseases anxiety and/or depressive state that for example hypertension, peptic ulcer etc. occur together have good treatment Effect, hence it is evident that improve patient mental and somatization.As the basic medication of body and mind comorbidity, the potential applicability in clinical practice of Tandospirone is wide It is wealthy.
At present, it is clinically many to be treated using the citrate (i.e. tandospirone citrate) of Tandospirone.1451 There are 150 (10.3%) adverse reaction occur in example patient, main adverse reaction there are drowsiness 43 (3.0%), lurched 16 (1.1%), nauseous 13 (0.9%), taediumvitae l1 (0.8%), unhappy 11 (0.8%), loss of appetite 10 Example (0.7%), also a few patients occur with the elevated dysfunction of liver of AST, ALT, jaundice etc..At present temporarily without pertinent literature report The reason for road causes above-mentioned adverse reaction.

Beneficial effects of the present invention are further illustrated below by way of pharmacodynamics test and clinical test:
Medicament composition capsule agent, the tandospirone citrate of each group is made according to the methods described of embodiment 5 in following each groups Composition is made by the following method:Original quality group is made by comparative example 1, and Quality advance group 1 is by the 2nd in the table 2 of embodiment 2 Group is made, and Quality advance group 2 is made by the 3rd group in the table 2 of embodiment 2, and Quality advance group 3 is by the 6th group in the table 4 of embodiment 4 It is made, Quality advance group 4 is made by the 5th group in the table 4 of embodiment 4.
Experiment 1:The clinical test of pesticide effectiveness
Use the clinical examination that pharmaceutical composition of the present invention carries out polycentric random, double blinding, placebo parallel control is studied Test, patient's sum is 120 people, be randomly divided into 3 groups, the age, inclusion criteria was the slight anxious patients to moderate from 24 to 65 years old And meet with disease of digestive system, mucosal lesion or easy bleeding, more than 50 years old age wherein at least one condition.In research Period patient is prohibited from using other sedatives, anti-inflammatory agent, muscle relaxant, depressor, antipsychotic drug, antidepressants or antianxiety Medicine.Each group takes placebo, original quality group and (contains the citrate of 0.62% chemical compounds I, the Chinese holly of 0.46% compound ii respectively Same regimen acid salt, the citrate of 0.25% compound III), Quality advance group 3 citrate of 0.05% chemical compounds I (contain).Medication After 30 days, curative effect (antianxiety curative effect carries out evaluation analysis according to Hamilton anxiety scale) and adverse reaction evaluation are carried out.Its In, the effective percentage of placebo is 10%, and adverse reaction rate is 5%;The effective percentage of original quality group is 65%, bad anti- It is 35% to answer incidence;The effective percentage of Quality advance group 3 is 75%, and adverse reaction rate is 15%.
Clinical observation result shows, original quality group and Quality advance group are respectively provided with obvious curative effect, and Quality advance group Rate of adverse reactions be significantly lower than original quality group, illustrate Quality advance group not only with anxiolytic effect, it is not Good reaction also has obvious reduction.
Experiment 2:Hepatotoxicity wind agitation is tested
The serious adverse reaction of tandospirone citrate composition, which is used for a long time, includes the damage to liver, below by small The long term administration of mouse tests to investigate degree of impairment of the tandospirone citrate composition to liver of different quality group.
120 18~22g of body weight male ICR mouse is randomly divided into 6 groups, every group 20, each administration group is as shown in table 5 Medicine and dosage continuous gavage be administered 28 days, blank group physiological saline gavage, takes fasting 12h before blood, the 29th by 1 times/day It takes two parts of blood by eyeball rear vein beard, and transaminase AST and concentration of ALT in serum are determined respectively.
Test data mean+SDRepresent, data analysis is carried out with SPSS softwares.Compare between group Using one-way analysis of variance (One-Way ANOVA), with P<0.05 and P<0.01 is with significant difference.
The influence of table 5, long term administration to liver function
Compared with blank control group:#P<0.05,##P<0.01;Compared with original quality group:*P<0.05, * * P<0.01.
Result of the test shows, is administered alone daily using routine dose, and original quality group is compared with blank group, mice serum Middle AST and concentration of ALT significantly raise (##P<0.01);And use the tandospirone citrate composition after Quality advance to give daily Medicine, compared with original quality group, AST and concentration of ALT rising condition are significantly reduced in mice serum, especially Quality advance group 2、3、4(**P<0.01);And AST and ALT concentration is with citrate, the compound ii of chemical compounds I in Quality advance group Citrate and compound III citrate content reduction and reduce, show use quality improve after the smooth degree of citric acid Spiral shell one compositions significantly reduce its toxicity to liver, and drug safety is higher.
Experiment 3:Antidepression animal model experiment
