[0256] The compounds of Examples 1 to 30 were used for pharmacological activity experiments:
[0257] CCK8 anti-tumor activity test:
[0258] Logarithmically growing HCT-116 cells, SW-480 cells, and Caco-2 cells were digested with trypsin and counted. The cell density was 2000 cells / well and the cells were evenly inoculated in a 96-well plate at 37°C and 5% CO. 2 The cells were cultured at a constant temperature for 24 hours under the same conditions, the culture medium was removed, and then 0.5 μmol / L of drug-containing culture medium was added to set up the experimental group, control group (5-fluorouracil), and blank group, with 4 replicate wells in each group. After adding the drug, the cells were incubated for 24 hours. After the incubation, 10 μL of CCK8 solution was added to each well and incubated for 3 hours. The absorbance of each well was measured at a wavelength of 450 nm using an ELISA reader. The cell survival rate of compound 1-30 was calculated based on the absorbance, and the IC 50 The calculation results are shown in Table 1 below.

[0262] in conclusion:
[0263] From the CCK8 data, we can see that compound 1-30 has a good inhibitory effect on colon cancer cells (HCT-116 cells, SW-480 cells, Caco-2 cells).
[0264] Inhibitory effect on HCT-116 cells, IC of compounds 1-20 50 The IC values of compounds 21-24 were between 79.64 and 172.34 μM. 50 The IC values of compounds 25-30 were between 45.08 and 63.57 μM. 50 The anti-tumor activity of compounds 21-30 was significantly better than that of compounds 1-20 at a concentration between 9.73 and 46.35 μM.
[0265] Inhibitory effect on SW480 cells, IC values of compounds 1-20 50 The IC values of compounds 21-24 were between 51.98 and 149.62 μM. 50 The IC values of compounds 25-30 were between 15.46 and 31.00 μM. 50 In the range of 10.11 to 35.21 μM, the antitumor activity of compounds 21-30 was significantly better than that of compounds 1-20, and the inhibitory effect of this type of compounds on SW480 cells was stronger than that on HCT-116 cells.
[0266] Inhibitory effect on Caco-2 cells, IC values of compounds 1-20 50The IC values of compounds 21-24 were between 40.64 and 135.42 μM. 50 The IC values of compounds 25-30 were between 9.62 and 19.51 μM. 50 In the range of 4.90 to 17.72 μM, the antitumor activity of compounds 21-30 was significantly better than that of compounds 1-20. Therefore, the inhibitory effect of compounds 21-30 on HCT-116 cells, SW-480 cells, and Caco-2 cells was stronger than that of compounds 21-30, which indicated that the activity of benzyl trifluoromethyl and difluoromethyl substitution was better than that of benzoyl substitution.
[0267] Compounds 1-30 generally have stronger inhibitory effects on Caco-2 cells than HCT-116 cells and SW-480 cells, among which compound 29 (IC 50 =4.90μM, 9.73μM) had a stronger inhibitory effect on Caco-2 cells and HCT-116 cells than the positive drug 5-fluorouracil (IC 50 =10.11 μM), and the inhibitory effect on SW480 cells was similar to that of the positive drug 5-fluorouracil (IC 50 =9.53 μM).
