This experiment selects gastric carcinoma cells MGC-803, human hepatoma cell strain Hep G2, human bladder cancer cell T-24, people non-
Small cell lung cancer cell NCI-H460 and human normal cell line HL-7702 totally 5 kinds of cell strains.
All tumor cell lines are cultivated containing 10wt% small ox bloods, 100U/mL penicillin, 100U/mL streptomysins
In RPMI-1640 culture solutions, 37 DEG C of 5%CO containing volumetric concentration are set2It is cultivated in incubator；Human normal cell line strain then cultivate containing
The small ox bloods of 10wt%, 100U/mL penicillin, 100U/mL streptomysins DMEM culture solutions in.
2, the preparation of untested compound
The DMSO liquid storages (a concentration of 0.002mol/L) of each untested compound are diluted successively by RMPI1640 culture mediums
At five concentration gradients, respectively 20,10,5,2.5,1.25 μm of ol/L, wherein cosolvent DMSO final concentration≤1%.It surveys first
Each untested compound of 20 μm of ol/L is tried for the inhibiting rate of tumor cell proliferation, is considered as primary dcreening operation result；Test is different respectively again
Each untested compound is to the Proliferation Ability degree of various tumour cells under gradient concentration, to the Fitting Calculation half-inhibition concentration,
That is IC50Value.
3, cell growth inhibition test (mtt assay)

1000~10000/hole (edge hole is filled with sterile PBS)；
(2) 5%CO2, 37 DEG C are incubated for 24 hours, until cell monolayer is paved with bottom hole, the drug 10 of a certain concentration gradient is added per hole
μ L, each concentration gradient set 4 multiple holes；
(3) 5%CO2, 37 DEG C are incubated 48 hours, are observed under inverted microscope；
(4) the MTT solution (5mg/mL PBS, i.e. 0.5%MTT) of 10 μ L is added per hole, continues to cultivate 4h；
(5) culture is terminated, culture solution in hole is carefully sucked, 150 μ L DMSO are added per hole and fully dissolve first a ceremonial jade-ladle, used in libation precipitation, shake
With wavelength it is 570nm in microplate reader, reference wavelength is the OD value that 450nm measures each hole after swinging device mixing；
(6) while zeroing hole (culture medium, MTT, DMSO) is set, (the drug dissolving of cell, same concentrations is situated between control wells
Matter, culture solution, MTT, DMSO).
(7) according to the OD value (OD values) measured, to judge living cells quantity, OD values are bigger, and cell activity is stronger.
Calculate the inhibiting rate of compound on tumor cell growth.For under primary dcreening operation concentration inhibiting rate be more than 50% cell
Strain, is further fitted by the inhibiting rate data of five concentration gradients of SPSS softwares pair, finds out compound to different tumours
Half-inhibition concentration (the IC of strain50Value, unit μm ol/L), IC of the compound for different cell strains50Value is as shown in table 1.
Table 1：The IC of 5 kinds of cell strains of compound pair of the present invention50It is worth (μm ol/L)
From the point of view of anti tumor activity in vitro test result, complex of the present invention has stronger antitumor activity,
Activity is substantially better than cis-platinum, is expected to exploitation into antitumor drug.
