Test example 2: drug effect test of compound of the invention on mouse ectopic inoculation of human gastric cancer cell line A549
Selecting 50 female Balb/c nude mice with the age of 6-8 weeks, and inoculating a human lung cancer cell line A549 tumor cell strain 5 x 10 to the subcutaneous ectopic position626 days after the inoculation of the tumor cells, the tumor grows to 60mm3~250mm3At that time, 12 mice were randomly selected and administered to test samples by gavage.
Mice were divided into a negative solvent control group, a compound of the invention group (example 1 compound, 20mg/kg) and a positive control Sitravatinib group (20mg/kg, purchased from Shanghai blue Wood chemical Co., Ltd.), each group containing 4 mice. All dosage groups adopt equal-volume unequal-concentration oral administration with single intragastric administration per day, and the administration volume is 10 mL/kg. The negative solvent control group was administered the same volume of blank vehicle (DMSO: Solutol: water 1: 2: 7) once a day for 15 consecutive days.
After the start of the administration, the body weight and tumor size of the mice were measured twice a week. Tumor size calculation formula:
tumor volume (mm)3) 0.5 × (tumor major diameter × tumor minor diameter)2)。
The antitumor efficacy was evaluated based on the growth curve of the tumor under treatment (i.e., tumor volume per measurement versus its number of days of treatment) and relative tumor volume. Wherein the relative tumor inhibition ratio (TGI) is calculated according to the following formula:
relative tumor inhibition TGI (%): TGI% (1-T/C) × 100%.
T/C% is the relative tumor proliferation rate, i.e., the percentage value of the relative tumor volume or tumor weight of the treated and control groups at a certain time point. T and C are the Relative Tumor Volume (RTV) or Tumor Weight (TW) at a particular time point in the treated and control groups, respectively. The calculation formula is as follows: T/C%RTV/CRTV×100%(TRTV: treatment group mean RTV; cRTV: vehicle control mean RTV; RTV-V0, V0 is the tumor volume of the animal at the time of grouping and Vt is the tumor volume of the animal after treatment). Or T/C% ═ TTW/CTW × 100% (TTW: average tumor weight at the end of the test in the treatment group and CTW: average tumor weight at the end of the test in the vehicle control group).

As shown in the figure, the compound can effectively inhibit the growth of tumor cells in a model mouse, and the relative tumor inhibition rate (TGI) is 107.58% by volume and is higher than 106.82% of positive control Sitravatinib.
