Abstract
Description
[0001] This application is a divisional application of the patent application filed on January 11, 2022, with application number 202210025250.5 and invention name “Evodia rutaecarpine derivatives with multi-target anti-tumor activity and their applications”. Technical Field
[0002] The invention belongs to the field of medical technology, and in particular relates to a class of evodia rutaecarpine derivatives with multi-target anti-tumor activity and applications thereof. Background Art
[0003] Topoisomerase (Top) is an important component of ribozymes and plays an important role in DNA transcription, replication and chromatin assembly. Top1 and Top2 induce transient breaks in single or double strands of DNA by cutting a single DNA strand.
[0004] In the field of DNA-targeted drugs, small molecules that stabilize c-MYC G-quadruplex (c-MYC G4) DNA are also considered a promising anticancer strategy. c-MYC is one of the most important oncogenes, which is overexpressed in more than 80% of cancer cells and contributes to cell proliferation, differentiation, and apoptosis. However, the transcriptional control of c-MYC is quite complex. c-MYC is difficult to target due to its short half-life and lack of binding pockets. Among various transcription factors, the nuclease hypersensitive element (NHE III1) controls 85-90% of c-MYC transcriptional activity, folding into DNA G-quadruplex (G4) under transcription-related negative supercoiling, thereby silencing c-MYC transcription. Therefore, c-MYC G4 has become a promising cancer-specific molecular target for anti-tumor drug discovery. In addition, the synergistic anti-tumor effect between c-MYC G4 and Top inhibitors has been confirmed. Therefore, simultaneous targeting of Top and c-MYCG4 will be a promising strategy for anti-tumor drug discovery.
[0005] In the early stage, researchers conducted in-depth research on the structure-activity relationship of evodiamine derivatives. Through the study of the anti-tumor mechanism, it was found that evodiamine derivatives are dual inhibitors of Top1 and Top2, which can effectively induce tumor cell apoptosis. The patent application with publication number CN101787025A discloses a substituted evodiamine antitumor and antifungal compound and its preparation method; the patent application with publication number CN1012311434A discloses an evodiamine compound and its preparation method and application; the patent application with publication number CN103992336A discloses an oxa- or thia-evodiamine antitumor derivative and its preparation method.
[0006] In view of this, there is an urgent need for a class of compounds that target Top and c-MYC G4 inhibitors to achieve synergistic anti-tumor effects. Summary of the invention

[0260] In vitro antitumor activity test of target compounds (IC 50 )
[0261] (1) Sample preparation: The target compound was prepared at 10 mM using DMSO.
[0262] (2) Cell lines: MCF-7 (human breast cancer cells), MDA-MB-231 (human breast cancer cells), HCT116 (human colon cancer cells), and HeLa (human cervical cancer cells) were all cryopreserved and passaged in our laboratory.

Tumor cells (MCF-7, MDA-MB-231, HCT116 and HeLa) in the logarithmic growth phase were digested with trypsin, and then the cells were diluted and suspended into a single cell suspension using culture medium (DMEM or PRMI1640 + 10% FBS + 1% double antibody). The cell density was adjusted to 5×10 4 / mL, 100 μL was added to each well and inoculated into a 96-well plate, and cultured in a 37°C, 5% CO2 incubator for 24 hours. Then, different concentrations of compounds were added, and three replicates were made for each concentration. Experimental and control groups were set up. After incubation for 72 hours, 10 μL CCK8 solution was added to each well, and then incubated at 37°C in the dark for 1-4 hours. The OD value at 450 nm was measured with a Biotek-Synergy microplate reader to calculate the half inhibitory concentration IC 50 .
