Test example:
2-carbonyl-2-phenylacetic acid salicyloyl hydrazone dibutyl tin title complex of the present invention, its Anticancer Activity in vitro is measured and is realized by MTT experiment method.
MTT analytical method:
Based on metabolism reduction 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide.Succinodehydrogenase in viable cell plastosome can make exogenous MTT be reduced to water-insoluble bluish voilet crystallization first a ceremonial jade-ladle, used in libation (Formazan) and be deposited in cell, and dead cell is without this function.First a ceremonial jade-ladle, used in libation in dimethyl sulfoxide (DMSO) (DMSO) energy dissolved cell, measures the optical density(OD) of characteristic wavelength, can indirectly reflect viable cell quantity by microplate reader.
Mtt assay is adopted to measure the 2-carbonyl-2-phenylacetic acid salicyloyl hydrazone dibutyl tin title complex of embodiment 1 preparation to the inhibit activities of human colon cancer cell (Colo205), human liver cancer cell (HepG2), human breast cancer cell (MCF7), human cervical carcinoma cell (Hela) and human lung carcinoma cell (NCI-H460).
Cell strain and culture system: Colo205, HepG2, MCF7, Hela and NCI-H460 cell strain takes from American. tissue incubator (ATCC).RPMI1640(GIBICO company with containing 10% foetal calf serum) substratum, in 5%(volume fraction) CO
2, carry out vitro culture in 37 DEG C of saturated humidity incubators.
Test process: join in each hole respectively by testing the concentration gradient of liquid (0.1ng/mL ~ 10ug/mL) according to concentration, each concentration establishes 6 parallel holes.Experiment is divided into drug study group (adding the test medicine of different concns respectively), control group (only add nutrient solution and cell, do not add test medicine) and blank group (only add cultivation medicine, do not add cell and test medicine).Orifice plate after dosing is placed in 37 DEG C, 5%CO
272h is cultivated in incubator.The activity of control drug measures according to the method for test sample.In orifice plate after having cultivated 72h, every hole adds MTT40uL(D-Hanks damping fluid and is made into 4mg/mL).After placing 4h at 37 DEG C, remove supernatant liquid.Every hole adds 150uLDMSO, and vibration 5min, makes Formazan dissolving crystallized.Finally, automatic microplate reader is utilized to detect the optical density(OD) in each hole at 570nm wavelength place.
Data processing: data processing uses GraphPadPrismversion5.0 program, title complex IC
50carry out matching by the nonlinear regression model (NLRM) in program with S shape dose response to obtain.
With MTT analytical method, human colon cancer cell (Colo205), human liver cancer cell (HepG2), human breast cancer cell (MCF7), human cervical carcinoma cell (Hela) and human lung carcinoma cell (NCI-H460) cell strain are analyzed, measure its IC
50value, result is as shown in table 1, conclusion is: from data in table, cancer therapy drug is used as with 2-carbonyl-2-phenylacetic acid salicyloyl hydrazone dibutyl tin title complex of the present invention, to human colon cancer cell (Colo205), human liver cancer cell (HepG2), human breast cancer cell (MCF7), human cervical carcinoma cell (Hela) and human lung carcinoma cell (NCI-H460), there is certain drug effect, can be used as the candidate compound of cancer therapy drug.
Table 12-carbonyl-2-phenylacetic acid salicyloyl hydrazone dibutyl tin title complex cancer therapy drug external activity test data.
2-carbonyl-2-phenylacetic acid salicyloyl hydrazone dibutyl tin title complex prepared by all the other embodiments is with the same test example of antitumour activity testing method of mtt assay to human colon cancer cell (Colo205), human liver cancer cell (HepG2), human breast cancer cell (MCF7), human cervical carcinoma cell (Hela) and human lung carcinoma cell (NCI-H460), and test result and table 1 are substantially identical.
