Effect Embodiment 1

(211) Test Method:

(212) CDK kinase inhibitory activity assay used LANCE® Ultra technique, test compounds were screened on CDK4/CycD3, CDK6/CycD3 and CDK2/CycA2 kinases at ATP concentration of Km. During the test, the initial concentration of the test compound was 3333 nM, each test compound set 10 serially diluted concentrations, the dilution fold was 3-fold, each concentration set 2 duplicated wells.

(213) CDK4/CycD3, CDK6/CycD3 and CDK2/CycA2 were purchased from Carna Biosciences, Inc.; dimethyl sulfoxide, ATP, DTT solution were purchased from Sigma-Aldrich; EDTA solution was purchased from GIBCO; LANCE® Detection Buffer, 10× and LANCE® Ultra Europium-anti-phospho-eIF4E-binding protein 1 (Thr37/46) and LANCE® Ultra ULight™-eIF4E-bindingprotein 1 (Thr37/46) Peptide were purchased from Perkinelmer.

(214) Test Procedure:

(215) 1. Take 10 mM stock solution of the test compound, in 96-well compound plate, DMSO was used to dilute the compound to an initial concentration of 100×, then this concentration was used as the first concentration, 3-fold diluted to make 10 serial concentrations; 1 μL each serial dilution was then added to 19 μL 1×reaction buffer to prepare 5×compound for use; 2 μL 5×compound was transferred from 96-well plate to 384-well plate; compound-free control well was added with 2 μL the following liquid: 1×reaction buffer with the addition of 1 μL DMSO; 2 μL 250 mM EDTA was added to the Min control well.

The control group Control was a drug-free, medium solution containing 0.2% DMSO. The untreated cell well was used to measure the background value which was recorded as Blank. The cell culture plate was placed at 37° C., COLO 205 cells were cultured in 5% CO.sub.2 condition for 6 days, A549 cells were cultured in 5% CO.sub.2 condition for 4 days.

(241) 3. Human breast cancer cells: After 6 days treatment of the test compound, 50 μL CellTiter detection solution was added to each well, the mixture was shaken for 2 min, mixed thoroughly, centrifuged, left to stand for 10 min, the fluorescent signal was recorded. The drug group was recorded as Drug D7. The control group was recorded as Control D7.

(242) 3′. COLO 205 cells and A549 cells: the microplate was taken out from incubator and equilibrated at room temperature for 30 minutes. 50 μL CellTiter-Glo® Luminescent Cell Viability Assay which had been equilibrated at room temperature was added to each well, the mixture was shaken at 700 rpm at room temperature for 2 minutes, the microplate was placed in HERAEUS Multifuge X1R centrifuge at 2000 rpm for 1 minute; equilibrated at room temperature for 10 minutes, the fluorescence signal value was measured on EnVision™.

If the weight loss exceeded 15%, the dosage regimen should be adjusted accordingly.

(284) Experiment Route:

(285) 1. Cell culture: human breast cancer cell line MCF-7 was cultured in a monolayer in vitro, the culture condition was in accordance with the supplier's technical specification or the references. Passage cells were treated with trypsin-EDTA for conventional digestion twice a week. When the cell saturation was 80%-90% and the quantity reached the requirements, cells were collected, counted, and inoculated.

(286) 2. Estrogen tablet inoculation and urination: 2 days before cell inoculation, the β-estradiol sustained-release tablet was inoculated into the left back of each mice. One week after inoculation, the animal urinated 3 times per week, the animal urinated daily if necessary.

(287) 3. Tumor cell inoculation: 0.2 mL 10×10.sup.6 MCF-7 cells was subcutaneously inoculated into the right back of each nude mice (PBS:Matrigel=1:1). When the average tumor volume reached 195 mm.sup.3, the compound was administered according to the dosage regimen (see Table 7).

(290) 5, Tumor measurement and experimental indicator: The experimental indicator was to examine whether the tumor growth was inhibit, delayed or cured. Tumor diameter was measured twice a week with a vernier caliper. The formula for calculating the tumor volume was V=0.5a×b.sup.2, a and b denoted the long diameter and short diameter of the tumor respectively. The antitumor activity of the compounds was evaluated by TGI (%) or relative tumor proliferation rate T/C (%). TGI (%) reflected the tumor growth inhibition rate. Calculation for TGI (%): TGI (%)=[(1−(mean tumor volume at the end of dosing of a treatment group−mean tumor volume at the beginning of dosing of the treatment group))/(mean tumor volume at the end of treatment of the solvent control group-mean tumor volume at the beginning of treatment of the solvent control group)]×100%. Relative tumor proliferation rate T/C (%): the calculation formula was as follows: T/C %=T.sub.RTV/C.sub.RTV×100% (T.sub.RTV: RTV of treatment group; C.sub.RTV: RTV of solvent control group). The relative tumor volume (RTV) was calculated based on the result of tumor measurement, the calculation formula was RTV=V.sub.t/V.sub.0, wherein V.sub.0 was the mean tumor volume measured at the beginning (d.sub.0) of dosing, and Vt was the mean tumor volume measured at a certain time, T.sub.RTV and C.sub.RTV took at the same day. At the end of the experiment, the tumor weight was measured and the tumor weight inhibition rate IR (%) was calculated: the calculation formula was IR (%)=(1-Tw/Vw)×100, Tw: mean tumor weight of the treatment group, Vw: mean tumor weight of the solvent control group.

(291) 6. Data summary and statistical analysis: The treatment group showed the best treatment effect on the 19th day after dosing at the end of the experiment. Therefore, based on the data, statistical analysis was performed to evaluate the differences between groups. T-test was used for the comparison between two groups, and one-way ANOVA was used for comparison among three groups or multiple groups. If the variance was not homogeneous, the Games-Howell method was used for test. If variance was homogeneous, the Dunnet (2-sided) method was used for analysis. All data analysis were performed with SPSS 19.0.p<0.05 was considered statistically significant.
