Abstract
The invention discloses a preparation method and application of tricyclohexyl tin indole-3-formate complex, which is a complex with the following structural formula (I). The invention also discloses a preparation method of the tricyclohexyltin indole-3-formate complex and application thereof in preparing antitumor drugs.
Description
Technical Field
The invention relates to a tricyclohexyltin indole-3-formate complex, a preparation method thereof and application of the complex in preparing antitumor drugs.
Background
Since Brown first discovered organotin carboxylates (CH 3 CO 2 SnPh 3 ) The synthesis, structure and biological activity research of the organotin carboxylate complex are widely focused by scientists since the biological activity of inhibiting the tumor of mice is inhibited. However, the known organotin compounds are generally highly toxic and therefore limited in application. Studies have shown that the structure, reactivity and biological activity of organotin compounds are related to both the hydrocarbon-based structure directly attached to the tin atom and the nature of the ligand. The organic tin complex structure is optimized through molecular design, so that the balance between toxicity and biological activity of the organic tin complex is regulated, and the organic tin complex is an important direction of current research. The coordination mode of tin atoms can be greatly changed by functionalizing hydrocarbon groups or ligands, so that the biological activity of the organotin complex is affected. Studies have shown that the toxicity of organotin compounds is related to the relative molecular massThe smaller the relative molecular mass, the greater the toxicity, while the more sterically hindered the tin hydrocarbyl is of greater relative molecular mass. Therefore, the novel large steric hindrance alkyl tin complex is synthesized, and the structure and the biological activity of the complex are researched, so that the complex has important research significance.
It is well known that azacyclic rings are important and common structural units of medicines, pesticides, functional materials, etc., most of which are closely related to life systems, so that studying the structure of organotin derivatives of such ligands can provide useful information not only for the disclosed anticancer mechanism, but also for the development of novel drugs as possible molecular designs. It is necessary to synthesize a novel nitrogen-containing heterocyclic organotin carboxylate compound and conduct a study on the bioactivity of the compound, the nitrogen-containing heteroatom carboxylic acid being an important carboxylic acid ligand. For example, chinese patent CN101402650B discloses an application of a dibutyl tin and quinolinecarboxylic acid complex in preparing medicines for treating gastric cancer, nasopharyngeal carcinoma, human liver cancer or leukemia.
Based on the fact that the tricyclohexyl tin hydroxide is a substance with good biological activity, and the cyclohexyl has the characteristics of large steric hindrance, large molecular weight and the like, the tricyclohexyl tin hydroxide is selected to react with the ligand indole-3-formic acid under certain conditions, and the complex with strong inhibition activity on A549 (human lung cancer cells), hela (human cervical cancer cells) and HGC-27 (human gastric cancer cells) is synthesized, so that a new approach is provided for developing anticancer drugs.

test example:
the tricyclohexyltin indole-3-formate complex is characterized in that the in-vitro anticancer activity determination is realized by an MTT (methyl thiazolyl tetrazolium) experimental method.
MTT assay:
based on the metabolic reduction of 3- (4, 5-dimethylazol-2-yl) -2,5-diArenyltetrazolium bromide. Succinate dehydrogenase in the mitochondria of living cells reduces exogenous MTT to water insoluble blue-violet crystalline Formazan (Formazan) and deposits in cells, whereas dead cells do not. Dimethyl sulfoxide (DMSO) can dissolve formazan in cells, and the optical density of characteristic wavelength can be measured by an enzyme-labeled instrument, so that the number of living cells can be indirectly reflected.
Human lung cancer cells (A549), human cervical cancer cells (Hela), and human gastric cancer cells (HGC-27).
Cell lines and culture system: a549, hela, and HGC-27 cell lines were obtained from American Tissue Culture Collection (ATCC). With 10% fetal bovine serum in RPMI1640 (GIBICO) medium at 5% (volume fraction) CO 2 In vitro culture was performed in a saturated humidity incubator at 37 ℃.
The testing process comprises the following steps: the test liquid medicine (0.0625 mu mol/L-0.5 mu mol/L) is added into each hole according to concentration gradient, and 3 parallel holes are arranged for each concentration. The experiments were divided into drug test groups (with different concentrations of test agent added), control groups (with only culture fluid and cells without test agent) and blank groups (with only culture fluid and no cells and test agent). The orifice plate after the drug addition is placed at 37 ℃ and 5 percent CO 2 Culturing in an incubator for 24 hours. The activity of the control drug was determined by the method of the test sample. In the well plate after 48 hours of incubation, MTT 20uL (5 g/L in PBS) was added to each well. After 4h at 37℃the supernatant was removed. 150uL DMSO was added to each well and the mixture was shaken for 10min to dissolve Formazan crystals. Finally, absorbance values of each well were measured at 570nm using a BioTek multifunctional microplate reader.
And (3) data processing: data processing using the GraAr Pad Prism version5.0 program, complex IC 50 Fitting is performed through a nonlinear regression model with S-shaped dose response in the program.
The IC of the human lung cancer cell (A549) cell strain, the human cervical cancer cell (Hela) cell strain and the human gastric cancer cell (HGC-27) cell strain are determined by an MTT assay 50 Values, results are shown in table 1, conclusions are: as can be seen from the data in the table, the tricyclohexyltin indole-3-formate complex of the present invention is used as an anticancer drug for human lung cancer, human cervical cancer and human stomachThe anticancer activity of the cancer is higher, and the compound can be used as a candidate complex of anticancer drugs.
Table 1 tricyclohexyltin indole-3-carboxylate complex anticancer drug in vitro activity test data.
| Human lung cancer cell | Human cervical cancer cell | Human gastric cancer cell | |
| Cell strain | A549 | Hela | HGC-27 |

The test methods of the anti-cancer activity of the tricyclohexyltin indole-3-formate complex prepared in the other examples on human lung cancer cells (A549), human cervical cancer cells (Hela) and human gastric cancer cells (HGC-27) by using the MTT method are the same as those of the test examples, and the test results are basically the same as those of Table 1.
