Cisplatin was used as a positive control.
The specific method comprises respectively growing cell lines in logarithmic growth phase at a ratio of 1 × 104Inoculating to 96-well plate at concentration of one/ml, placing at 37 deg.C and containing 5% CO2Culturing for 24 hours in the incubator, discarding the old solution, replacing the fresh culture solution, adding the sterilized compound to be detected, continuing culturing for 48 hours, discarding the culture solution, adding 20ul of RPMI 1640 culture solution containing 5mg/ml MTT into each well, continuing culturing for 4 hours, carefully removing the supernatant, adding 100 mul of DMSO into each well, shaking for about 10min to dissolve the precipitate, and detecting the OD value with a microplate reader with the wavelength of 490 nm. Cell viability was determined for each sample concentration using the following formula:

Experimental example 2 acute toxicity test in mice
Kunming mice (provided by Xinjiang experimental animal research center, the qualification number is SCXK 2011-one 0001, the weight is 19-20g, half of each mouse is female and male, each 10 mice form a group, the solvent adopts physiological saline and 0.5% CMC-Na solution, according to the pre-test result, each drug to be tested is designed into five-grade dose, the dose interval is 0.8 times, after each drug to be tested is weighed, a small amount of Tween 80 is added for wetting and dissolving assistance in the experiment, and then the drugs are gradually addedGradually adding 0.5% CMC-Na solution to the required concentration. The experimental volume was 0.5ml/20g mouse. A single intraperitoneal administration is adopted. The Kunming mice are taken and randomly grouped according to sex, each group is respectively administrated in the abdominal cavity according to the dosage setting, and the instant reaction of the mice after administration is observed. Dead animals were observed dissectively, surviving animals were observed for two additional weeks, and animal deaths were recorded for two weeks. After two weeks, the surviving animals were dissected and the parenchymal organ was observed for pathological examination. Based on the number of deaths in each group of animals, the half-Lethal Dose (LD) of the drug was calculated by the Bliss method50Value).
The results of the tests are shown in Table 2 below.

Anti-tumor experiment BABL/C mice and C57One group of 8-10 BL/6 mice, and two groups of negative controls; the tumor source adopts mouse Lewis lung cancer and H22 liver cancer (maintained by pharmacologic laboratory passage of Xinjiang Huashi Dan medicine research Limited liability company); the solvent adopts physiological saline and 0.5 percent CMC-Na solution; the tested drugs are respectively administered to LD in abdominal cavity of the drug by a single administration501/5 for the value is benchmark; weighing each sample to be tested, adding a small amount of Tween-80 for wetting and dissolving aid during experiment, and gradually adding 0.5% CMC-Na solution to the required concentration. The experimental volume was 0.5ml/20g mouse. The preparation is administered to abdominal cavity 1 time per day for 10 days, and 10 times. The negative control was given an equal volume of the corresponding solvent, and the dosing regimen was all intraperitoneal, 1 time per day for 10 consecutive days. Positive control Cyclophosphamide (CTX) was administered once daily for 7 consecutive days at a dose of 30 mg/kg. Adopting an in vivo anti-tumor axillary subcutaneous inoculation model: taking tumor source with vigorous growth under aseptic condition, homogenizing to obtain about 1 × 1070.2 ml/mouse is inoculated to the axilla of the corresponding host subcutaneously, the administration is carried out according to the experimental design scheme on the next day, each group of animals is killed in about three weeks, the tumor is dissected and weighed, and the tumor inhibition rate is calculated according to the following formula:
percent tumor inhibition is [ (average tumor weight in negative control group-average tumor weight in administration group)/average tumor weight in negative control group ] × 100%
