- Test Example 5 In vivo pharmacodynamic study of the compound of formula (I) in human myeloma MM.1S cell subcutaneous xenograft tumor CB-17SCID model
- Cell culture human multiple myeloma cell MM.1S( CRL-2974 TM ), semi-suspension culture in vitro, culture condition is ATCC-form ⁇ Lated RPMI-1640 Medium medium with 10% fetal bovine serum, 100U/ml penicillin and 100 ⁇ g/ml streptomycin, 37°C, 5% CO 2 Cultivation in an incubator. Passages are processed twice a week. When the number of cells reaches the requirement, the cells are collected, counted, and seeded.
- MM.1S cells (with matrigel, volume ratio 1:1) were subcutaneously inoculated on the right back of each mouse, and the group administration was started when the average tumor volume reached 130 mm 3. Seven days is a dosing cycle, and the compound is administered twice a day with an interval of 12 hours each time.
- the compound of formula (I) is administered orally for a total of four cycles.
- the anti-tumor efficacy is determined by dividing the average tumor increase volume of animals treated with the compound of formula (I) by the average tumor increase volume of untreated animals.
- Table 9 Test results of compounds of formula (I) in human myeloma MM.1S cell subcutaneous xenograft tumor CB-17SCID model
- TGI Tumor Growth Inhibition (tumor growth inhibition rate).
- TGI(%) [1-(Average tumor volume at the end of treatment in a certain treatment group—Average tumor volume in the treatment group at the time of treatment)/(Average tumor volume at the end of treatment in the solvent control group—Average tumor volume at the start of treatment in the solvent control group Volume)] ⁇ 100%.
