Experimental technique
Remove serum deprivation by the substratum washed twice pair cell that uses 200 μ l not contain serum, the substratum that 90 μ l is not contained serum joins in each hole. flat board is incubated 2-3 hour.To join in each hole as substratum, carrier (substratum that does not contain serum), negative control (antagonist) or the test compounds in the substratum that does not contain serum and the standard substance (final concentration is the 10uM solution of the 10 μ l of 1uM) that 10 μ of positive control contain serum. flat board is turned back in the insulation can.After 18 hours, add [
3H] adenosine (0.5 μ Ci/ hole) do not contain in the substratum of serum at 10 μ l, and flat board turned back in the insulation can.After 4 hours, add trypsin 0.25%) (100 μ l/ hole).Flat board is turned back in the insulation can.After 1 hour, by filtering termination test fast through Whatman GF/B glass fibre filter.For example use Brandel MLR-96T cell harvestor, with 500ml 50mM Tris-HCIpH7.0 damping fluid washing nozzle.For example, use the radioactivity (50% significant quantity) of the reservation on the Wallac 1205Betaplate liquid scintillation counter assessment filter.Intrinsic activity is defined as total intake (1 μ M Kui pyrrole sieve) deducts the substratum that does not contain serum, test compounds and 1 μ M Kui pyrrole sieve that is categorized as 100% intrinsic activity (DA agonist fully) are compared.All tests are all preferably according to carrying out in triplicate, and wherein every kind of medicine accounts for complete row in each flat board.Compound of the present invention preferably shows the intrinsic activity of 1%-90% at least, the more preferably activity of 10%-90% at least, the more preferably activity of 10%-80% at least, the more preferably intrinsic activity of 20%-60%, more preferably at least 30% one 50% intrinsic activity at least.Test-results is seen Fig. 5.

Anti-schizophrenia activity test in the Compound I I-1 body
Test materials
1. the preparation of reagent and solution and dosage
Apomorphine: Apomorphine is dissolved in 0.1% the xitix, is made into the solution of 10mg/kg dosage.
Aripiprazole is dissolved in the physiological saline, is made into the solution of 5mg/kg dosage, ultrasonicly makes dissolving.
Risperidone is dissolved in the physiological saline, is made into the solution of 0.25mg/kg dosage.
Compound I I-1 is made into 20mg/kg, and is now with the current.
2. experimental animal and grouping
Female KM mouse, 18-22g. when test mouse are divided into solvent control group, model control group, positive controls at random, and respectively are subjected to the reagent group.Behavior observation is tested every group of 5 mouse.Movable observing is tested every group of 4 mouse.
3. test method
3.1 mouse administration: irritate stomach by 0.1ml/10g respectively for the group mouse and give respectively to be subjected to reagent.
3.2 mouse modeling: giving to be subjected to after the reagent 30 minutes, is the Apomorphine solution of 10mg/kg with concentration, carries out abdominal injection with 0.1ml/10g mouse body weight respectively.
After 3.3 stereotypic behavior observation mouse gives Apomorphine, whether mouse perpendicular tail occurs, smells, gnaws, jumps, climbs stereotypic behaviors such as wall, new line in observed and recorded preceding 30 seconds in the time of the 5th, 10,15,20,25,30 minutes respectively, and mark by following standard: 0 grade, no above-mentioned behavior appearance in 30 seconds that observe; 1 grade, the appearance of the above-mentioned behavior of discontinuous moderate in 30 seconds that observe; 2 groups, the appearance of the above-mentioned behavior that successive is strong in 30 seconds that observe.
4. the processing of test-results
Statistics is respectively organized the stereotyped movement number of 6 time point accumulative totals of mouse, calculates the mean value of every mouse, and its result represents with mean ± SD.
5 statistical methods
The stereotypic behavior test-results adopts the LSD method to add up; The movable number of times of mouse is observed and is adopted the variance analysis and the Q-test of replicate measurement to add up.
6, stereotyped movement behavior observation experimental result (seeing Fig. 6 and Fig. 7), among Fig. 6,1 is model group, and 2 is the risperidone group, and 3 is group of solvents, and 4 is A Li piperazine azoles group, 5 are Compound I I-1 group.
This test-results shows: compare with model group, risperidone, A Li piperazine azoles, Compound I I-1 can obviously reduce each time point stereotyped movement number and the accumulative total stereotyped movement number of mouse, show that it has tangible antipsychotic effect.
