Abstract
Description
Technical Field
[0001] The present invention belongs to the field of chemical medicine, and particularly relates to a degrader of cyclin-dependent protein kinase 12 / 13 (CDK12 / 13), a pharmaceutical composition thereof, and applications thereof. Background Art
[0002] Protein kinases are key regulatory molecules of cell functions and constitute one of the largest and most functionally diverse gene families. By phosphorylating substrate proteins, protein kinases direct the activities, localizations, and overall functions of many proteins and are involved in almost all cellular activities. Abnormalities in the expression, activation, localization, etc. of protein kinases are closely related to the occurrence and development of various diseases and are important driving factors for various diseases such as tumors and inflammation. As of December 31, 2020, the FDA has approved a total of 62 kinase inhibitor drugs for market. Research has found that the non-kinase functions of proteins play important roles in diseases such as tumors. The non-kinase functions of kinases such as CDK6, FAK, EGFR, PIPK3, PDK1, BRAF, CRAF, CHK2, ZAP70, AKT, and Aurora A have been reported in the literature. Therefore, simply inhibiting the activity of kinases cannot completely inhibit the non-kinase functions of kinases, which may bring potential adverse effects such as low efficacy and drug resistance. Therefore, developing protein degraders is expected to comprehensively inhibit the enzymatic activity and non-kinase functions of kinases and exert a potent therapeutic effect. Protein degraders based on the PROTAC principle are currently the most successful and mature protein degradation strategies and have been successfully used for the development of degraders for multiple kinases and other targets.
[0003] PROTAC specifically refers to a class of small molecule compounds that can specifically recognize and induce the degradation of target proteins; the molecular structure consists of three parts: a target protein recognition ligand, a Linker, and an E3 recognition ligand. The advantage of PROTAC is that it can not only effectively inhibit the kinase activity of target proteins but also rapidly degrade and remove target proteins. In theory, only a catalytic amount of the drug is required to degrade almost all proteins (including membrane proteins) in cells, so it has high safety, drug resistance, and broad application prospects. Currently, degraders for target proteins such as ERR, ABL, BET, and CDK4 / 6 have been successfully developed, and the results show that they can not only treat the proliferation of gene-driven tumors but also overcome inhibitor resistance. In 2018, Pfizer announced an investment of $830 million in the research and development of protein degrader drugs based on PROTAC technology. In March 2019, Arinas, a partner of WuXi AppTec, announced that its developed protein degrader ARV-110 for androgen receptor entered clinical research; this is the world's first protein degrader to enter the clinical research stage.
[0004] CDK12 / 13 (Cyclin-dependent kinase 12 / 13) belongs to the cyclin-dependent kinase (CDK) family of serine / threonine protein kinases and forms a complex with Cyclin K to exert its biological functions. CDK12 and CDK13 contain 1,490 and 1,512 amino acids respectively and share 46% homology. The kinase domain consists of 300 amino acids with a homology as high as 92%. CDK12 / 13 forms a complex with Cyclin K to phosphorylate the C-terminal domain (CTD) of RNA polymerase II (RNA PolII). The CTD consists of a highly repetitive sequence of seven amino acids, YSPTSPS. In humans, the CTD contains a 52-repeat unit. CDK12 / 13 mainly phosphorylates Ser2 to regulate transcription and post-transcriptional mRNA processing. Genetic studies have shown that CDK12 promotes the production of full-length gene transcripts by inhibiting the cleavage of intronic polyadenylation sites. Many homologous recombination repair genes (such as BRCA1 / 2, ATM, ATR, FANCD2, FANCI, etc.) contain more intronic polyadenylation sites. Therefore, the expression of these genes is more sensitive to the loss or inhibition of CDK12. Compared with other transcription CDKs, the N-terminus of CDK12 / 13 contains an additional arginine / serine-rich (RS) motif, which is commonly found in proteins involved in pre-mRNA splicing. Proline-rich motifs (PRIM) are also found in the N- and C-termini and may serve as binding sites for proteins containing SH3, WW, or profilin domains. These structures suggest that CDK12 / 13 may have non-kinase functions (such as protein-protein interactions) that play important roles in mRNA splicing and mRNA 3'-end processing. Therefore, using only kinase inhibitors of CDK12 / 13 as probe tool molecules to study the biological functions of CDK12 / 13 is far from sufficient. Inducing the degradation of CDK12 / 13 using proteolysis-targeting chimeras (PROTACs), while inhibiting both its kinase and non-kinase functions, has great potential in studying the biological functions of CDK12 / 13 and disease treatment and has attracted increasing interest from scientists in recent years.

These compounds can effectively and highly selectively degrade the CDK12 / 13 protein kinase and inhibit the proliferation, migration, and invasion of various tumor cells.

[0264] Example 23: Test of the CDK12 / 13 Degradation Activity of Representative Compounds in MDA-MB-231 Cells
[0265] Experimental method: The cell line MDA-MB-231 was purchased from the American Type Culture Collection (ATCC). Detection was performed using conventional Western Blot as follows: MDA-MB-231 cells were seeded in a 12-well plate at a density of 4×10 5 / mL, 1 mL per well, and cultured overnight in an incubator for cell attachment. Subsequently, a certain concentration of the compound was added and the cells were treated for 15 h. The cells were lysed with lysis buffer and protein samples were collected. An appropriate amount of the sample was subjected to SDS-PAGE electrophoresis. After electrophoresis, the proteins were transferred to a polyvinylidene difluoride (PVDF) membrane using a wet electrotransfer system. The electrotransferred PVDF membrane was cut into several required strips, and then placed in a blocking solution (5% skim milk diluted in TBS containing 0.1% Tween 20) and blocked at room temperature for 1.5 h. The primary antibodies against the corresponding target proteins were diluted in TBS containing 0.1% Tween 20 according to the dilution requirements of different antibodies, such as 1:1000 (CST), 1:3000 (Proteintech, Bethyl), 1:200 (Santacruz), to prepare the primary antibody solutions. The blocked membranes were placed in the corresponding primary antibody solutions and incubated at 4 °C for 12 - 14 h. Subsequently, they were washed three times with TBS containing 0.1% Tween 20, 5 min each time. The washed membranes were placed in a secondary antibody solution (horseradish peroxidase-labeled goat anti-rabbit IgG, diluted 1:2000 in TBS containing 0.1% Tween 20) and reacted at room temperature for 2 h. After washing the membranes three times as above, they were developed with StarSignal plus reagent and Omni-ECL reagent and photographed with an Amersham Imager 800 system.
[0266] Figure 1 The results showed that some compounds could effectively degrade the protein levels of CDK12 and CDK13 in cells, such as compounds ZLC4-91, ZLC4-93, ZLC5-6, ZLC5-11, ZLC5-31, ZLC5-103, ZLC5-104, ZLC5-106, ZLC6-1, ZLC6-37, and ZLC6-42, etc. Compound ZLC5-11 could degrade the CDK12 and CDK13 proteins in MDA-MB-231 cells in a time-dependent manner. After treating MDA-MB-231 cells at a concentration of 1 μM for 15 h, the CDK12 and CDK13 proteins in the cells were almost completely degraded. In addition, ZLC5-11 was found to have a time-dependent degradation effect on the CDK12 and CDK13 chaperone protein Cyclin K. After 15 h, the Cyclin K protein in the cells had been almost completely degraded.
[0267] We further determined the degradation of CDK12 and CDK13 proteins in MDA-MB-231 cells by representative compounds ZLC5-6, ZLC5-31, ZLC5-11, ZLC6-37, ZLC6-42, and ZLC5-15 at different concentrations ( Figure 2 ). The experimental results showed that these representative compounds could degrade CDK12 and CDK13 proteins in MDA-MB-231 cells in a dose-dependent manner, and the target proteins could be effectively degraded at a concentration of 1 μM ( Figure 2 ).

(B) WB results of CDK13 protein degradation after treating MDA-MB-231 cells with some compounds at a concentration of 0.1 μM for 15 hours. (C) Using DMSO in the control group as a reference standard, the protein levels were quantified by the gray values of the bands in the WB result images (Figure A and Figure B). (D) Compound ZLC5-11 degraded CDK12 and CDK13 proteins in MDA-MB-231 cells in a time-dependent manner, and the target proteins could be significantly degraded at 15 h.

[0270] Example 24: Study on the proliferation inhibitory activity of compounds against triple-negative breast cancer cell MDA-MB-231
[0271] The cell proliferation inhibitory activity of the compounds was determined using the Cell Counting Kit-8 Cell Viability Assay (Selleck.cn). The cells were seeded in a 384-well plate containing its corresponding medium ( PS 3701), and incubated in an incubator at 37 °C with 5% CO 2 . After incubating overnight, the high-concentration stock solutions of each compound to be tested were prepared; using 650 Liquid Handler the compounds were added to the 384-well plate at a certain concentration gradient. After drug administration, the cell plate was placed in an incubator at 37 °C with 5% CO 2 and incubated for 5 days. Subsequently, using (Thermo ScientificTM ) Add 5 μL of CCK-8 reagent to each well of a 384-well plate, and then put the plate back into the incubator for incubation for 1.5 - 2 h. After incubation, take out the plate, centrifuge to remove air bubbles, and then use Measure the absorbance values of each well at 450 nm and 650 nm, and use GraphPad Prism software (GraphPad Software Inc) to process and analyze the data.
[0272] Figure 3 The results showed that compounds capable of effectively degrading the protein levels of CDK12 and CDK13, such as ZLC4-77, ZLC4-91, ZLC5-6, ZLC5-31, and ZLC6-1, could effectively inhibit the growth of triple-negative breast cancer cells MDA-MB-231, and the IC 50 values for the MDA-MB-231 cell line were 610.4 nM, 622.5 nM, 497.9 nM, 389.0 nM, and 288.6 nM, respectively.

[0274] Pharmacokinetic and bioavailability tests in rats. SD rats were administered by single oral (10 mg / kg), intravenous (2.5 mg / kg), and intraperitoneal (10 mg / kg) injection. After administration, animal blood samples were collected at appropriate time points, anticoagulated with heparin, centrifuged at 8000 rpm for 6 minutes, and the supernatant was taken and stored at -20 °C for HPLC-MS analysis. The blood samples were precipitated with acetonitrile for protein at 12000 rpm * 10 min, and the supernatant was used for HPCL-MS analysis. The data were fitted with parameters using DAS2.0 to obtain compartment model and non-compartment model parameters respectively. The oral bioavailability of the compound was calculated according to the area under the plasma concentration-time curve (AUC) data. The results are shown in Table 1. The experimental results showed (Table 1) that the representative compounds zlc-4-91 and zlc-4-93 had excellent oral pharmacokinetic properties.
