[0139] Test for Inhibition of Cancer Cell Activity by Compound of Embodiment 19 (Taking Hepatocellular Carcinoma SMMC-7721 Cells as an embodiment):
Testing Method
(1) Cell Culture and Drug Effect
[0140] SMMC-7721 cells are cultured in DMEM high sugar medium containing 10% fetal bovine serum in a saturated humidity incubator at 37 °C and 5% CO2. The culture medium is changed every two days and passaged every 3-4 days. The drug is prepared as 1 mmol/L and 10 mmol/L storage solution using DMSO as solvent, when used, the concentration is diluted into 1 .Math.mol/L and 10 .Math.mol/Lwith culture medium, using DMSO as negative control group and gemcitabine as positive control group to act on cells in logarithmic growth phase.
(2) MTT Colorimetry
[0141] Cells in logarithmic growth phase are digested with 0.025% pancreatin, and then digested with DMEM high sugar medium containing 10% fetal bovine serum. After centrifugation, the cells are suspended in DMEM high sugar medium containing 10% fetal bovine serum. Take a 96-well plate and add 200.Math.L of sterile water seal to each hole around the plate to ensure saturated humidity in the experiment. In the middle six rows, 100 .Math.L of cell suspension are added respectively, and the cell concentration is about 3.5×104 cells /mL. The last row is blank control group, and the same volume of complete culture medium is added. In 37 °C, 5% CO2 saturated humidity incubator culture for 24 hours, cells completely adhere to the wall, remove the culture medium, add complete culture medium containing different drugs, 200.Math.L per hole. The blank control group is added with 200 .Math.L of complete culture medium, and the culture is continued. After 24 hours, the drug effect is observed and photographed under an inverted microscope. After 48 hours, the drug effect is also observed and photographed under an inverted microscope. Then the supernatant is removed. 100 .Math.L of 0.5 mg/mL MTT solution is added to each well. After 4 hours of continuous culture, purple crystal formazan is generated. 100 .Math.L of 10% SDS is added to each well. After 12 hours of culture in an incubator at 37°C, the OD value is measured with an enzyme reader at A571 wavelength. Repeat 6 wells for each sample concentration, and calculate the inhibition rate by taking the average value.
Statistical Method
[0142] The experimental results are analyzed by SPSS11.5 and One-WayANOVA method, and P<0.05 showed that there are significant differences among the data.

[0144] After preliminary tests, it is found that most of the compounds had no obvious inhibitory effect on SMMC-7721 cells at a concentration of 1 .Math.mol/L, but showed significant inhibitory effect on SMMC-7721 cells at a concentration of 10 .Math.mol/L, with the inhibitory rate exceeding 95%; The inhibition rate of some compounds to SMMC-7721 is over 90% at 1 .Math.mol/Lconcentration or 10 .Math.mol/L concentration, such as A10, A11, A12 and A14; The inhibitory activity is significantly higher than that of the positive control drug gemcitabine.
[0145] The above experimental activity data show that the dithiocarbamate-containing 4-(N-methyl) aminopiperidine myricetin derivative has a certain inhibitory effect on liver cancer SMMC-7721 cells, and some target compounds show excellent inhibitory activity on liver cancer SMMC-7721 cells, can be used as potential drugs for inhibiting liver cancer SMMC-7721 cells, and has a good application prospect.
