Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of pharmaceutical chemistry, and specifically relates to a pyridylpiperazine derivative and a preparation method and application thereof. Background Art
[0002] Malignant tumors are one of the main causes of death in the world and have become a major disease that seriously endangers human life and health and restricts social and economic development. Lung cancer, breast cancer, stomach cancer, liver cancer, esophageal cancer, colorectal cancer, cervical cancer, prostate cancer, and lymphoma are the main common malignant tumors in my country.
[0003] Colon cancer is the third most common malignancy and the second most deadly malignancy. It is closely related to environmental and genetic risk factors. In recent years, the incidence and mortality rates have been increasing rapidly. The operation is difficult and the disease is prone to metastasis. Epidemiological studies have shown that an unbalanced diet (high in saturated fat and low in vegetables and fruits), lack of exercise leading to abdominal fat accumulation, excessive obesity, and a history of malignant tumors in first-degree family members are risk factors for colon cancer.
[0004] In recent years, although great progress has been made in chemotherapy for colon cancer, there are still some defects, such as: the commonly used anticancer drugs have a single mechanism of action, large toxic side effects, and long-term use can easily lead to chemotherapy resistance, which greatly reduces the treatment effect. According to statistics, about 90% of chemotherapy failures are related to chemotherapy resistance. Therefore, it is of great significance to develop new drugs for the treatment of colon cancer.

[0159] The beneficial effects of the present invention are demonstrated by experiments as follows.
[0160] Experimental Example 1: Cell proliferation inhibition experiment
[0161] 1. Experimental Methods
[0162] HCT-116 cells from ScienCell were cultured in a medium containing DMEM and placed in an incubator with a 5% CO2 concentration. After the cells were fully grown in the culture dish, they were passaged at a ratio of 1:2. HCT-116 cells of generations 3-8 were selected for the experiment. The inhibitory effect of the synthesized target compound on the proliferation of HCT-116 cells was measured using the MTT method, and AZ191 was selected as a positive control drug. IC was calculated using SPSS software 50 value.
[0163] 1) Experimental principle
[0164] Thiazolyl blue, referred to as MTT, is a detection reagent that can be used to detect the content of live cells and cytotoxicity. Succinate dehydrogenase in the mitochondria of living cells can reduce exogenous MTT to water-insoluble blue-purple crystalline formazan and deposit it in the cells, while dead cells do not have this function. Dimethyl sulfoxide (DMSO) can dissolve the formazan in cells, and its light absorption value can be measured at a wavelength of 490nm using an enzyme-linked immunosorbent assay, which can indirectly reflect the number of live cells. Within a certain range of cell numbers, the amount of MTT crystals formed is proportional to the number of cells.
[0165] 2) Experimental Materials
[0166] a. Cell line: Human colon cancer cell line (HCT-116)
[0167] b. Reagents and instruments: DMEM medium (HyClone), culture dishes (JETBIOFIL), 96-well plates (CorningCostar), trypsin (Biological Industries, BI); MTT reagent (Biofroxx); cell culture incubator (ThermoFisher); microplate reader (BioTek Instruments, Inc).
[0168] 3) Experimental methods
[0169] a. Cell culture and plating: cells were cultured in DMEM medium. After the cells were fully grown, the medium was discarded, and the cells were washed with PBS for 3 times. An appropriate amount of trypsin was added and the cells were digested in an incubator for 1 min. The digestion was terminated with DMEM medium, and the cells were blown off and placed in a centrifuge tube. The cells were centrifuged at 1200 rpm for 4 min, and the supernatant was discarded. An appropriate amount of fresh DMEM medium was added and the cells were blown off and mixed. The cells were counted with a cell counting plate to obtain the number of tumor cells in the medium.
[0170] b. Cell dosing: dilute the cell-containing medium to a suitable concentration and add it to a 96-well plate, with 180 μl of medium per well. The number of cells in each well is maintained at 1×10 4 Then, the cells were placed in a 5% CO2 incubator for 24 hours. After the cells adhered to the wall, the medium was aspirated and 200 μl of serum-free medium containing blank concentration, 0.25 μM, 0.5 μM, 1 μM, 2 μM, 5 μM, 10 μM and 20 μM concentrations of compound 20 were added. Three parallel control groups were set up for the wells with different concentrations. The 96-well plate after drug addition was transferred to a low oxygen incubator with 1% O2 and 5% CO2 and cultured for 48 hours. After 48 hours, the medium was removed and 50 μl of medium containing 2% MTT was added. The OD value was detected after incubation for 5 hours.
[0171] c. Data processing: IC 50 The value was calculated by SPSS. The anti-proliferation level of the compound on cells was calculated according to the following formula:
[0172] Inhibition rate (%) = (blank control well OD value - drug addition well OD value) / (blank control well OD value - cell-free well OD value) × 100%

[0178] The above experimental results show that the compounds of the present invention have broad application prospects in the preparation of drugs for preventing and / or treating tumors.
