[Abstract]:With the continuous development of molecular biology research, the molecular targeting therapy of malignant tumor has become the fourth treatment methods except surgery, radiotherapy and chemotherapy, and more and more clinical treatment of malignant tumors. Angiogenesis is closely related to tumor growth, invasion and metastasis, in order to inhibit tumor angiogenesis as a target for tumor treatment. The method has become one of the new antitumor therapies. Lenalidomide is a new immunomodulator with antitumor activity, which is mainly manifested in inhibiting tumor angiogenesis. In this paper, a series of amines were designed by the virtual screening study on the molecular targets of tumor angiogenesis inhibition by the ramification. The molecular structure of the derivatives. Based on the optimization of the synthesis of amines, a series of amines were synthesized and obtained, and their pharmacological activities were studied. The research on the anti-tumor mechanism of the amines derivatives and the theoretical and experimental basis for the development of molecular targeting tumor angiogenesis inhibitors were provided. The screening of the molecular targets of tumor angiogenesis by amido, and the design and virtual screening of the molecular structure of the inhibitors. Using the reverse docking method, the initial structure of the amine (chemical named 3- (4- amino -1,3- two hydrogen -1- -2H- isoindole -2- based) -2,6- piperidine two ketone) was the initial structure, and six angiogenesis was selected on the AutoDock 4 platform. Promoting factor target proteins, such as vascular endothelial growth factor receptor (VEGFR-2), epidermal growth factor receptor (erbB-3), fibroblast growth factor receptor (FGFR-4), BCR-ABL tyrosine kinase (ABL), p38 mitogen activated protease (p38MAPK) and matrix metalloproteinase (MMP-3), are studied. By analyzing the docking results, the initial determination is made. The potential target of diamine inhibition of tumor angiogenesis is that FGFR-4. uses molecular docking to dock the designed 54 amines with FGFR-4 and determine the synthesis of 30 target compounds, including alkylated derivatives, acyl derivatives and sulfonylated derivatives. Secondly, the combination of amines and its derivatives A synthetic route to the synthesis of amines and their intermediates was reviewed to determine the synthetic route of the amines. Since the amine was used as a raw material, 30 diamine derivatives were synthesized by the study of its amino derivatives (alkylation, acylation and sulfonylation). Through the investigation of solvent, temperature, catalyst, condensation agent, and acid binding agent, The optimum reaction conditions for each step reaction were determined in the process of synthesis. The synthesized target compounds were characterized by nuclear magnetic resonance spectroscopy, nuclear magnetic resonance carbon spectroscopy and mass spectrometry, and 28 compounds were not reported. Finally, the antitumor activity of the amine and its derivatives in vitro was studied by CCK-8. The cytotoxicity test of the amines and their derivatives on the esophageal cancer cell line EC9706 showed that both amines and their derivatives had certain inhibitory activity, and the inhibitory activity of amines to EC9706 was 340.3 u g/m L (delta G=-7.05 kcal/mol), and the inhibitory activity of the three amino derivatives on EC9706 was selected. IC50 is 309.5 mu g/mL (delta G=-7.19 kcal/mol), 263.8 g/mL (delta G=-7.68kcal/mol) and 225.2 mu g/mL (delta G=-8.40 kcal/mol). It is found that the modified alkylation, acylation and sulfonylation of amines have better inhibitory activity than lauryl amine, and the inhibitory activity of sulfonylated derivatives is most prominent. The results of the cytotoxicity test of amidodiamine and its derivatives to EC9706 are in agreement with the molecular docking results, indicating that it is feasible to inhibit the molecular target of tumor angiogenesis as the direction of the amines and its derivatives. It can be further determined that FGFR-4 is the target of antitumor angiogenesis of amido.
