Embodiment 17: the antitumour activity vitro test
The compound (I-1), (I-2), (I-3) and (IV) that make among the embodiment are carried out people's lung cancer and human breast carcinoma biological activity test.The DDP(cis-platinum) medicine in contrast, cis-platinum is the chemicals commonly used of cancer therapy, has higher curative effect.
Testing method: tetrazolium reduction method (mtt assay).
Cell strain: human lung carcinoma cell line A-549 and human breast cancer cell strain MCF-7.Above-mentioned tumor cell line is available from Chinese Academy of Sciences's Shanghai school of life and health sciences cell bank.
Experimental procedure is as follows:
(1) preparation of sample: for solvable sample, every 1mg dissolves with 40 μ L DMSO, gets 2uL and dilutes with 1000 μ L nutrient solutions, and making concentration is 50 μ g/mL, uses the nutrient solution serial dilution to working concentration again.
(2) cultivation of cell
1) culture medium preparation: contain 800,000 unit penicillin in per 1000 milliliters of substratum, 1.0 gram Streptomycin sulphates, 10% inactivated fetal bovine serum.
2) cultivation of cell: tumor cell inoculation in substratum, is put 37 ℃, 5%CO
2Cultivate in the incubator, 3~5d goes down to posterity.
3) working sample is to the restraining effect of growth of tumour cell
Cell is digested with EDTA-trysinization liquid, and be diluted to 1 * 10 with substratum
6/ milliliter is added in the 96 porocyte culture plates, and every hole 100uL puts 37 ℃, 5%CO
2Cultivate in the incubator.Behind the inoculation 24h, add the sample with the substratum dilution, every hole 100 μ L, each concentration adds 3 holes, puts 37 ℃, 5%CO
2Cultivate in the incubator, add the MTT of 5mg/mL behind the 72h in the cell cultures hole, every hole 10 μ L put 37 ℃ and hatch 3h, add DMSO, every hole 150 μ L, and with the vibrator vibration, Shi Jia Za dissolves fully, with microplate reader colorimetric under the 570nm wavelength.With similarity condition with not containing sample, contain same concentration DMSO culture medium culturing cell in contrast, calculation sample is to the IC of growth of tumour cell
50
The result of test is as shown in the table:
