Description
Technical Field
The invention relates to the technical field of medicinal chemistry, in particular to a pyridine substituted chalcone compound or pharmaceutically acceptable salt thereof, and a preparation method and application thereof.
Background
Microtubules are the major components of the cytoskeleton and play an important role in maintaining cell morphology, cell division, signal transduction, etc., and therefore, tubulin is a promising target for novel chemotherapeutic drugs. Tubulin inhibitors can prevent the hyperproliferation of tumor cells and are an important class of anti-tumor therapeutic drugs. Currently, clinically used microtubule inhibitors mainly include drugs for inhibiting tubulin depolymerization, represented by paclitaxel, and drugs for inhibiting tubulin aggregation, represented by vinblastine. The drugs have the defects of large toxic and side effects, large synthesis difficulty, poor water solubility, easy generation of drug resistance and the like.
Disclosure of Invention

And taking the compound mother liquor, diluting the compound mother liquor by times to a final concentration, and using the compound mother liquor for subsequent tests. Concentrations were set at 5, and each concentration was biologically repeated 3 times. The amount of tubulin (cytoskeleton) at 2mg/mL was resuspended in PEM buffer [80mM PIPES (pH6.9), 0.5mM EGTA, 2mM MgCl 2 And 15% glycerol]Then preincubated with compound or solvent DMSO for 5 minutes on ice. Before the tubulin polymerization was detected, GTP-containing PEG was added to a final concentration of 3 mg/mL. The absorbance was measured at 340nm after 30 minutes by means of a Berthold LB941 microplate-type multifunctional microplate reader. By setting blank control group, Graphpad calculates IC of different compounds 50 Results are in μ M.

Collecting cultured hepatocarcinoma H22 cells, counting, and adjusting cell suspension concentration to 1.5 × 10 7 One per ml, 0.1ml was inoculated subcutaneously per axilla on the right side of nude mice. Measuring the diameter of the nude mouse transplanted tumor with a vernier caliper, and after 7 days of tumor cell inoculation, the tumor grows to 50-75mm 3 At this time, 10 mice were divided into 9 groups at random. Dissolving the compound in DMSO, dripping poloxamer mother liquor, and adding physiological saline to required dosage. The final concentration of DMSO was 1% and the final concentration of poloxamer was 2%. Each group of nude mice is administrated, the abdominal cavity of the model group is injected with equal amount of solvent for 1 time per day for 21 days; injecting 20mg/kg cis-platinum into tail vein of the positive control group, injecting 1 time per day for 21 days; experimental groups 20mg/kg of example 7, 13, 20, 23, 24, 30, CA-4 was injected intravenously. 1 injection per day for 21 days; the nude mice were sacrificed 21 days after the end of the administration, and the tumor mass was surgically removed and weighed. Tumor growth inhibition (%) was calculated, the results were analyzed by SPSS 17.0, and statistical analysis was performed between groups by t-test, which was calculated as follows:
2. Results of the experiment
TABLE 4 in vivo antitumor Activity of some of the Compounds of the invention
And (4) conclusion: it can be seen from the table that the compounds of examples 7, 13 and 30 showed better tumor growth inhibition activity, and the inhibition rates thereof were higher than those of the positive control cisplatin group and the CA-4 group, and the examples had better effect on the body weight of mice than the cisplatin group, which indicates that the compounds in the examples had less toxicity and better drug efficacy than cisplatin.
And (IV) the combination of part of compounds and TACC3 inhibitor inhibits drug-resistant tumor cell experiments:
as a member of the human acidic coillimated-coil-binding protein family, Transforming acidic coillimated-coil-binding protein 3(TACC3) is a key central body protein, which is up-regulated in many cancers. Although the specific mechanism of action of TACC3 is not clear, the combination of TACC3 inhibitor and paclitaxel tubulin inhibitor can effectively improve the sensitivity of paclitaxel-resistant tumor cells to the tubulin inhibitor, and is a potential strategy for solving the drug resistance of the tubulin inhibitor. After the partial compounds are combined with the TACC3 inhibitor KHS101, the sensitivity of drug-resistant tumor cells to the compounds can be greatly increased, the growth of the drug-resistant tumor cells can be effectively inhibited, and a new way for treating tumors by using the tubulin inhibitor is provided.
1. Experimental methods
(1) Tumor sensitive cells (HCT-8, A549) and tubulin-resistant tumor cells (HCT-8/Taxol, A549/Taxol) are digested, counted and prepared to a concentration of 5 × 10 4 Cell suspension at Per Ml, 100. mu.l of cell suspension per well in 96-well plates (5X 10 per well) 3 Individual cells);
(2) the 96-well plate was placed at 37 ℃ in 5% CO 2 Culturing in an incubator for 24 hours;
(3) the compounds representing examples 7 and 30 were diluted with complete medium to the desired concentration, and then 100ul of the medium containing examples was added to each well, while 5 μ M of the TACC3 inhibitor KHS101 was added to the tumor-resistant cell group;
(4) the 96-well plate was placed at 37 ℃ in 5% CO 2 Culturing for 72 hours in an incubator;
(5) MTT method:
a. MTT staining of 96-well plates, λ 490nm, and OD determination;
b. 20Ml MTT (5mg/Ml) was added to each well and the incubation was continued in the incubator for 4 hours;
c. discarding the culture medium, adding 150Ml DMSO into each well for dissolving, and shaking for 10 min to mix gently; lambda is 490nm, and an enzyme-labeling instrument reads the OD value of each hole;
(6) calculating an inhibition rate:
2. results of the experiment
Combination of the compound of Table 5 with the TACC3 inhibitor KHS101 for the inhibition of drug resistant tumor cells
And (4) conclusion: as can be seen from the table, the fold-resistance of examples 7 and 30 to drug-resistant tumor cells is smaller than that of paclitaxel, indicating that the compounds of the present invention are not easy to generate drug resistance. After the exemplified drugs 7 and 30 and the TACC3 inhibitor KHS101 are combined for use, the sensitivity of drug-resistant tumor cells to compounds can be greatly increased, the growth of the tumor drug-resistant cells can be inhibited, and a new way is provided for overcoming clinical tumor drug resistance at present.
