Abstract
Description
A cyano aromatic ring derivative and its pharmaceutical application Technical Field
[0001] This invention belongs to the field of pharmaceutical formulations, specifically relating to a pharmaceutical formulation comprising a therapeutically effective amount of an active ingredient M and a pharmaceutical excipient, wherein the active ingredient M is selected from compounds of general formula (I) or their stereoisomers, tautomers, or pharmaceutically acceptable salts. This invention also relates to the use of the pharmaceutical formulation in the preparation of cancer-related drugs. Background Technology
[0002] Prostate cancer is a type of cancer that is often discovered in its early stages. Its causes are frequently related to genetic factors, a high-fat diet, and endocrine disorders. Generally, the incidence of prostate cancer is higher in developed countries than in developing countries. In 2016, there were 120,000 new cases of prostate cancer in China, and this number is projected to reach 237,000 by 2030, with a market share of $4.8 billion. Early-stage prostate cancer patients can be treated radically and have a longer survival time. However, late-stage patients with metastatic cancer undergo castration combined with anti-androgen therapy, and the disease progresses to castration-resistant prostate cancer. Clinical studies show that most patients with castration-resistant prostate cancer overexpress the androgen receptor (AR). Inhibiting the androgen receptor (AR) signaling pathway has a significant therapeutic effect on patients with hormone-resistant prostate cancer; therefore, inhibiting the androgen receptor (AR) is an effective way to directly block this pathway.
[0003] PROTAC (proteolysis targeting chimera) molecules are bifunctional compounds that can simultaneously bind to target proteins and E3 ubiquitin ligases. These compounds can be recognized by the cell's proteasome, causing the degradation of the target protein and effectively reducing its concentration in the cell. By introducing ligands that can bind to different target proteins into PROTAC molecules, it has become possible to apply PROTAC technology to the treatment of various diseases, and this technology has received widespread attention in recent years.
[0004] Therefore, it is necessary to develop novel PROTAC drugs targeting the androgen receptor (AR) for the treatment of androgen receptor-related tumors. Summary of the Invention

Glass microelectrodes were fabricated from glass electrode blanks (BF150-86-10, Sutter) using a stretching device. The tip resistance after perfusion with electrode fluid was approximately 2-5 MΩ. The glass microelectrodes were inserted into the amplifier probe to connect to the patch-clamp amplifier. Clamp voltage and data recording were controlled and recorded using pClamp 10 software via computer, with a sampling frequency of 10 kHz and a filtering frequency of 2 kHz. After obtaining whole-cell recordings, the cells were clamped at -80 mV to induce hERG potassium current (Ig). hERG The step voltage was applied from -80 mV to +20 mV for 2 seconds, then repolarized to -50 mV for 1 second before returning to -80 mV. This voltage stimulation was applied every 10 seconds, and the drug administration process began after the hERG potassium current stabilized (at least 1 minute). Each test concentration of the compound was administered for at least 1 minute, and at least 2 cells (n≥2) were tested for each concentration.

The degree of inhibition of hERG potassium current (the peak hERG tail current induced at -50mV) by different compound concentrations was calculated using the following formula:
[0647] Inhibition%=[1–(I / Io)]×100%
[0648] Where Inhibition% represents the percentage of inhibition of hERG potassium current by the compound, and I and Io represent the amplitude of hERG potassium current before and after drug administration, respectively.
[0649] Compound IC 50 The following equation was used to fit and calculate the result using GraphPad Prism 5 software: Y=Bottom+(Top-Bottom) / (1+10^((LogIC)) 50 -X)*HillSlope))

[0680] Human prostate cancer cells LNCAP (AR T878A mutant expression) were cultured in complete medium of RPMI 1640 + 10% FBS + 1% penicillin-drug antibiotics at 37°C in a 5% CO2 incubator. Cells in the exponential growth phase were collected and the cell suspension was adjusted to the appropriate concentration using experimental medium (phenol red-free RPMI 1640 + 1% carbon-adsorbed fetal bovine serum + 0.5% PS). Cells were seeded in 12-well plates at 1.5 × 10⁶ cells / well. 5Cells / well. After plating, the compound diluted with experimental culture medium was added, and the cells were incubated in a CO2 incubator for 24 hours. After incubation, cells were collected, and RIPA lysis buffer (cocktail (Beyotime, Cat. P1010), RIPA (Beyotime, Cat. P0013B, RIPA lysis buffer is prepared by mixing cocktail and RIPA at a ratio of 1:100) was added and lysed on ice for 15 minutes. After centrifugation at 12000 rpm and 4°C for 10 minutes, the supernatant protein sample was collected. Protein quantification was performed using a BCA kit (Beyotime, Cat. P0009). The protein was then diluted to 0.4 mg / mL, and the expression of AR (Abcam, Cat. ab133273) and the internal control β-Actin Mouse mAb (CST, Cat. 3700S) was detected using a fully automated Western blot quantitative analyzer (Proteinsimple). The expression level of AR T878A relative to the internal reference was calculated using the fully automated protein expression quantification software "Compass for SW". The data processed according to equation (9) were then analyzed using GraphPad Prism 8.0 software, and a four-parameter nonlinear regression model was used to calculate DC. 50 The values are: Protein% = Protein administration / Protein solvent × 100% (Equation 9)
[0681] Conclusion: The compounds of the present invention, such as the compounds in the examples, have good degradation activity against AR T878A protein in LNCAP cells.
[0682] 18. Plasma stability test
[0683] This experiment used plasma samples from five species—human, monkey, dog, rat, and mouse—to evaluate the stability of the test compound in plasma. Compound 11 or the working solution of the control compound was diluted to 2000 ng / mL plasma samples using blank plasma from humans, dogs, rats, and mice (organic reagent content less than 5%). The plasma samples were incubated at 37°C for 0 min, 6 h, and 24 h, after which acetonitrile containing an internal standard was added to terminate the reaction.
[0684] The concentration of analytes in samples was semi-quantitatively determined using liquid chromatography-tandem mass spectrometry (LC-MS / MS), excluding standard curves and quality control samples. The concentration in the sample was expressed as the ratio of the analyte peak area to the internal standard peak area. Retention times of analytes and internal standards, chromatogram acquisition, and chromatogram integration were performed using Analyst software (Sciex, Framingham, Massachusetts, USA). Plasma stability = 100 * T 6h or 24h / T 0min
