Antitumor activity evaluation method:
In the present invention, antitumor activity evaluation method adopts mtt assay, and concrete operations are as follows: the human carcinoma cell line of phase growth of taking the logarithm, counts after refinement.3 × 10
3(190 μ L) is inoculated in 96 porocyte culture plates in individual/hole.24h adds the testing sample solution of 10 μ L different concns after cell attachment, testing sample is made to be respectively 1 μ L, 2 μ L, 5 μ L, 10 μ L, 20 μ L and 50 μ L often organizing the ultimate density in hole, often group has three parallel holes at least, and process cell is to the fixed time.Before measuring, every hole adds 20 μ LMTT solution (MTT sterile PBS buffer is made into the solution of 5mg/mL), 37 DEG C hatch 4h after, careful sucking-off supernatant liquor, every hole adds the DMSO of 200 μ L, concussion 15min, crystallisate is fully dissolved, evenly.570nm place absorbance is measured by microplate reader.The OD value of each test hole is deducted background OD value (perfect medium adds MTT, acellular), the OD value of each parallel hole is averaged.Cell survival rate %=(dosing cell OD value-background OD value)/(compared with control cells OD value-background OD value) × 100%.Each check point gets the mean value of three parallel holes, draws and suppresses curve, calculates IC
50value.
