[0108] Experiment 1: Breast cancer cell toxicity experiment
[0109] Test subjects: breast cancer cells MCF-7, triple-negative breast cancer cells MDA-MB-231
[0110] Test method:
[0111] 1. Antitumor activity experiment
[0112] Cell culture
[0113] Human breast tumor MCF-7 and MDA-MB-231 cells were cultured in a culture medium containing 1.5 g / l NaHCO3, 10% FBS, insulin (10 mg / l) and penicillin / streptomycin (100 U / ml and 100 μg / ml). All cell culture processes were carried out in an incubator at 37°C containing 5% CO2 and 95% air.
[0114] 1.2. Cytotoxicity (survival rate) test
[0115] The antitumor activity of the indicated compounds against human breast tumor cell lines MCF-7 and MDA-MB-231 was evaluated by determining the tumor cell survival rate induced by the indicated compounds.
[0116] Preparation of drug: The compounds obtained in Examples 1 to 7 and 8-1 to 8-3 are used as test drugs, and appropriate amounts of each are taken to prepare 1.0×10 -3 mol / L DMSO solution; take an appropriate amount of cisplatin and dissolve it in physiological saline to make 5×10 -3 mol / L solution. The cells were seeded into a 96-well plate so that each well contained 1×10 4 Cells were cultured overnight at 37°C in a 5% CO2 incubator. After 24 hours, the culture medium was replaced with a series of fresh culture medium containing different concentrations of the test drug or cisplatin as a control.
[0117] Cultivate in a 37°C, 5% CO2 incubator for 48 hours, add 10 μl CCK-8 reagent (CellCounting Kit) to each well, continue incubation at 37°C for 1 hour, and then record the absorbance (OD) at 450nm using a Victor V spectrophotometer. Correct the results with the blank culture medium as the benchmark, and perform 6 replicates of each test drug concentration to obtain the average value. This is used as the experimental group.
[0118] That is, the experimental groups were wells containing cells, culture medium, and CCK-8 reagent added later.
[0119] The following two comparison groups were also set up:
[0120] Comparative group 1: No drugs were added to the cells in the wells, i.e., compared with the “experimental group”, the test drugs were eliminated, with the purpose of determining the absorbance OD value caused by the natural proliferation of cells in the absence of drugs;
[0121] Comparative group 2, the wells contained no cells but culture medium and CCK-8 reagent added later; that is, compared with the "experimental group", cells were eliminated in order to determine the background absorbance OD value caused by the composition of culture medium, CCK-8 and culture well materials;
[0122] The cytotoxicity was calculated using the following formula:
[0123] Cytotoxicity = [(A c -A s ) / (A c -A b )]×100%,
[0124] A c Refers to the OD value of cells in the wells of control group 1 (without test drug); A s Refers to the OD value in the wells of the experimental group (containing culture medium, CCK-8, cells and a certain concentration of test drug); A b is the OD value in the wells of control group 2 (containing culture medium, CCK-8 and test drug). The IC value of the test drug was obtained based on the cytotoxicity curves at different concentrations of the test drug. 50 value.
[0125] Table 1 shows the half-lethal concentration of each test compound for human tumor cell lines MCF-7 and MDA-MB-231, and the migration inhibition rate).
[0126] Table 1. Toxicity of di-hydrate-tri-ammonia-triphenylphosphine ruthenium salt compounds to breast cancer
[0127]
[0128]
[0129] The half-lethal concentration of each compound on breast cancer cells in Table 1 above shows that, compared with the control drug cisplatin, the di-hydrate-tri-ammonia-triphenylphosphine ruthenium salt compound prepared by the present invention has a much stronger killing ability on breast cancer cells MCF-7 and MDA-MB-231 than the widely used clinical drug cisplatin, and is a potential substitute for cisplatin. The toxicity of the compounds of the present invention to breast cancer cells is generally similar, so when selecting lead compounds, more consideration can be given to candidates with less toxicity to healthy cells.
[0130] Experiment 2: Inhibition of breast cancer cell migration
[0131] Test subjects: breast cancer cells MCF-7, triple-negative breast cancer cells MDA-MB-231
[0132] Test method:
[0133] According to literature reports, the effect of test drugs on tumor cell migration can be measured by cell scratch assay. Tumor cells were seeded into 24-well plates, cultured in a 37°C incubator to about 80-90% cell coverage, and washed with serum-free medium. The test drug was added to a final concentration of 2.5 μM, and the cell layer was scratched with a sterile pipette tip and gently washed with 1× PBS. The cell scratch profile was photographed at the same location immediately (0 hours) and 24 hours later, and the width of the scratch (W) was measured. The migration rate was calculated as follows:
[0134] (W 0h -W 24h ) / W 0h × 100%. The results are shown in Table 2 below.
[0135] Table 2. Effect of di-hydrate-tri-ammonia-triphenylphosphine ruthenium salt compounds on the inhibition of breast cancer migration
[0136]
[0137]
[0138] It can be seen that the compound of the present invention has a good inhibitory effect on the migration of breast cancer cells, and the inhibitory ability on triple-negative breast cancer cells MDA-MB-231 is better than that on estrogen receptor-positive strain MCF-7 tumor cells. However, the traditional anti-tumor cisplatin has no such activity or has a very low activity. In comparison, 2-mercaptonicotinic acid silver di-hydrate-tri-ammonia-triphenylphosphine ruthenium has better anti-tumor activity.
[0139] Experiment 3: The breast tumor cells MCF-7 and MDA-MB-231 were replaced with normal breast epithelial cells MCF-10A. The experiment was carried out according to the method described in Experiment 1, breast cancer cell toxicity experiment. The results are listed in Table 3 below.
