Description

Pyridine or pyrazine tricyclic compounds and their pharmaceutical compositions and applications

[0001] This invention claims priority to Chinese Patent Application No. 2024105153505, filed on April 26, 2024, entitled "Pyridine or pyrazine tricyclic compounds and pharmaceutical compositions and applications thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of medicinal chemistry, and more particularly to pyridine or pyrazine tricyclic compounds, their pharmaceutical compositions, and applications. Background Technology

[0003] Malignant tumors (cancer) are a major malignant disease threatening human health. Conventional treatments for cancer include radiotherapy, chemotherapy, surgical resection, and drug therapy. However, these methods often have drawbacks such as significant side effects, unsatisfactory treatment outcomes, and problems with tumor prognosis, recurrence, and metastasis. Therefore, there is an urgent need to develop new treatment technologies to address these issues in cancer treatment. Personalized treatment and targeted therapy have been seen in recent years as the hope for breaking through the current bottlenecks in cancer treatment.

[0004] Molecular targeted therapy for tumors is a novel treatment approach developed by regulating key signaling pathways closely related to tumor growth through chemical or biological means. Targeted small molecule drugs are characterized by high specificity, strong selectivity, and relatively mild toxicity; they can be used alone or in combination with existing drugs for cancer treatment. Since the application of small molecule targeted drugs, represented by imatinib mesylate (Novartis), in 2001, tumor targeted therapy has developed rapidly over the past two decades. Currently, dozens of protein kinase small molecule targeted drugs are on the market, becoming an important class of drugs in cancer treatment and ushering in a new era for tumor chemotherapy.

[0005] RIOK2 is a pseudokinase highly expressed in various tumors, including gastric cancer, colon cancer, melanoma, glioblastoma, and non-small cell lung cancer, and is directly related to tumor progression. Heterocyclic structures, as "life-saving agents," are core structures in many drug molecules. Developing anti-tumor drugs based on novel heterocyclic structures is an important direction in drug development. In previous work, the inventors of this invention synthesized and constructed a series of distinctive fused-heterocyclic / chiral heterocyclic small molecule libraries, screened for novel lead compounds, and further obtained the highly active and selective RIOK2 (Right Open Reading Frame kinase 2) inhibitor, triazoloquinone compound CQ211, through derivatization and optimization. However, this compound has poor solubility in water and organic solvents, and its pharmacokinetic properties and in vivo activity are not ideal, lacking good drug-likeness. Therefore, there is an urgent need to develop new small molecule targeted drugs with better drug-likeness and good in vitro and in vivo activity. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a pyridine or pyrazine tricyclic compound that exhibits good inhibitory activity against RIOK2 protein, can highly inhibit the proliferation of various tumor cells, and possesses good pharmacokinetic properties.

Detailed Implementation

[0103] In the compounds described in this invention, when any variable (e.g., R) 8 R 9 If a component (e.g., a substituent) appears more than once in any component, the definition of each occurrence is independent of the definition of each subsequent occurrence. Similarly, combinations of substituents and variables are permitted, provided such combinations stabilize the compound. A line drawn from a substituent into the ring system indicates that the bond referred to can be attached to any substituted ring atom. If the ring system is polycyclic, it means that such a bond is attached only to any suitable carbon atom of a neighboring ring. It should be understood that those skilled in the art can select the substituents and substitution patterns of the compounds of this invention to provide chemically stable compounds that can be readily synthesized from readily available starting materials using techniques in the art and the methods described below. If a substituent is itself substituted by more than one group, it should be understood that these groups can be on the same carbon atom or on different carbon atoms, as long as the structure is stable.

This aromatic ring can be monocyclic, bicyclic, or polycyclic, and includes, but is not limited to: quinolinyl, pyrazolyl, pyrroloyl, thiophenyl, furanyl, pyridyl, pyrimidinyl, pyrazinyl, triazolyl, imidazolyl, oxazolyl, isoxazolyl, pyridazinyl, etc. "Heteroaryl" is also understood to include any N-oxide derivative of a nitrogen-containing heteroaryl group. The linkage of heteroaryl groups can be achieved through carbon atoms or through heteroatoms.

[0110] As will be understood by those skilled in the art, the term “halo” or “halogen” as used herein refers to chlorine, fluorine, bromine, and iodine.

[0111] This invention includes the free forms of compounds of formulas I-IV, as well as their pharmaceutically acceptable salts and stereoisomers. Some specific exemplary compounds described herein are protonated salts of amine compounds. The term "free form" refers to an amine compound in its non-salt form. Pharmaceutically acceptable salts include not only exemplary salts of the specific compounds described herein, but also typical pharmaceutically acceptable salts of the free forms of all compounds of formulas I-IV. The free forms of specific salts of said compounds can be separated using techniques known in the art. For example, the free form can be regenerated by treating the salt with a suitable dilute aqueous solution of a base, such as dilute aqueous solution of NaOH, potassium carbonate, dilute ammonia, or sodium bicarbonate. The free form may differ somewhat from its respective salt form in certain physical properties, such as solubility in polar solvents, but for the purposes of this invention, such acid salts and base salts are otherwise pharmaceutically equivalent to their respective free forms.

[0112] Pharmaceutically acceptable salts of the present invention can be synthesized from compounds of the present invention containing either a basic or acidic moiety using conventional chemical methods. Typically, salts of basic compounds are prepared by ion-exchange chromatography or by reacting a free base with a stoichiometric or excess amount of the desired salt form of an inorganic or organic acid in a suitable solvent or a combination of solvents. Similarly, salts of acidic compounds are formed by reacting with a suitable inorganic or organic base.

[0113] Therefore, pharmaceutically acceptable salts of the compounds of the present invention include conventional non-toxic salts of the compounds of the present invention formed by reacting an alkaline compound of the present invention with an inorganic or organic acid. For example, conventional non-toxic salts include salts derived from inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, aminosulfonic acid, phosphoric acid, nitric acid, etc., and also include salts prepared from organic acids such as acetic acid, propionic acid, succinic acid, glycolic acid, stearic acid, lactic acid, malic acid, tartaric acid, citric acid, ascorbic acid, pyric acid, maleic acid, hydroxymaleic acid, phenylacetic acid, glutamic acid, benzoic acid, salicylic acid, p-aminobenzenesulfonic acid, 2-acetoxybenzoic acid, fumaric acid, toluenesulfonic acid, methanesulfonic acid, ethanedisulfonic acid, oxalic acid, hydroxyethylsulfonic acid, trifluoroacetic acid, etc.

[0114] If the compounds of this invention are acidic, then a suitable "pharmaceutically acceptable salt" refers to a salt prepared from a pharmaceutically acceptable non-toxic alkali, including inorganic and organic bases. Salts derived from inorganic bases include aluminum salts, ammonium salts, calcium salts, copper salts, iron salts, ferrous salts, lithium salts, magnesium salts, manganese salts, manganese salts, potassium salts, sodium salts, zinc salts, etc. Ammonium salts, calcium salts, magnesium salts, potassium salts, and sodium salts are particularly preferred. Salts derived from pharmaceutically acceptable organic non-toxic bases, including salts of primary, secondary, and tertiary amines, wherein substituted amines include naturally occurring substituted amines, cyclic amines, and basic ion exchange resins such as arginine, betaine, caffeine, choline, N,N'-dibenzylethylenediamine, diethylamine, 2-diethylaminoethanol, 2-dimethylaminoethanol, aminoethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N-ethylpiperidine, glucosamine, glucosamine, histidine, hydroxycobalamin, isopropylamine, lysine, methylglucosamine, morpholine, piperazine, piperidine, guanidine, polyamine resins, procaine, purine, theobromine, triethylamine, trimethylamine, tripropylamine, aminobutanetriol, etc.

[0115] Berg et al., “Pharmaceutical Salts,” J. Pharm. Sci. '1977: 66: 1–19, describe in more detail the preparation of the pharmaceutically acceptable salts described above and other typical pharmaceutically acceptable salts.

[0116] Since the deprotonated acidic portion of the compound, such as the carboxyl group, can be anionic under physiological conditions, and this charge can then be balanced by the protonated or alkylated basic portion, such as the tetravalent nitrogen atom, which carries a cation, it should be noted that the compounds of the present invention are potential internal salts or zwitterions.

[0537] Affinity Kd test of pyridine or pyrazine tricyclic compounds to RIOK2 kinase

[0538] KINOMEscan TM The technology is the industry's most comprehensive high-throughput screening system for detecting the effects of compounds against a large number of human kinases (Fabian et al. (2005) Nat. Biotechnol. 23, 329; Karaman et al. (2008) Nat. Biotechnol. 26, 127). KINOMEscan TM This detection method is based on competitive binding, which quantitatively detects the binding ability of a compound to an enzyme by competitively binding the compound to the active site of an immobilized ligand. The assay mainly consists of three components: a kinase linked to a DNA tag, an immobilized ligand, and the compound being tested. The competitive ability of the compound to the immobilized ligand is determined by quantitative PCR of the DNA tag linked to the kinase.

[0539] Kinase activity assay: Kinase-tagged T7 phages were amplified in parallel in BL21-derived *E. coli* in 24-well plates. When *E. coli* reached the logarithmic growth phase, they were infected with frozen T7 phages (multiple of infection = 0.4) and incubated with shaking at 32°C until bacterial lysis (90–150 min). The lysate was centrifuged (6000 x g) and filtered (0.2 μm) to remove debris. The collected supernatant was used to infect HEK293 cells and amplified therein, thereby producing DNA-tagged kinases for qPCR detection. Biotin-linked small ligands were reacted with streptavidin-coated magnetic beads at room temperature for 30 min to provide affinity resin for the experiment. The liganded magnetic beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT) to remove unbound ligands and reduce nonspecific phage binding. The binding reaction involved mixing the kinase, magnetic beads containing the binding ligand, and 1x binding buffer (20% SeaBlock, 0.17×PBS, 0.05% Tween 20, 6mM DTT) with the test compound. The test compound was prepared as a 100X stock solution using 100% DMSO and diluted directly into the reaction system. All reactions were performed in 384-well polypropylene plates with a final reaction volume of 0.02 ml. The plates were incubated at room temperature with shaking for 1 hour. The magnetic beads were then washed with washing buffer (1×PBS, 0.05% Tween 20). The beads were resuspended in elution buffer (1×PBS, 0.05% Tween 20, 0.5 μM non-biotinylated affinity ligand) and incubated with shaking at room temperature for 30 minutes. The kinase concentration was determined by detecting the amount of DNA tag on the kinase using qPCR.

[0540] The constant (Kds) is obtained using the Hill equation and calculated from the standard dose-response curve:

[0541] The Hill slope value is -1.

[0542] Table 2 lists the representative compound numbers and their corresponding Kd results. The results showed that the pyridine or pyrazine tricyclic compounds of this invention exhibited strong binding affinity to RIOK2 kinase.

Compound 46 showed high affinity for these kinases, with a Kd of 12 nM for binding to RIOK2. Compound 59 exhibits a survival rate of less than 1% for the following kinases at a concentration of 1000 nM: m-TOR, PIK3C2B, PIK3C2G, PIK3CA(H1047L), PIK3CA(I800L), PIK3CD, PIK3CG, and VPS34. Compound 59 demonstrates a high affinity for these kinases.

Male BALB / c-Nude (6 weeks old) were purchased from Guangdong Yaokang Laboratory Animal Technology Co., Ltd. HGC-27 (2×10⁶) was used. 7 (200 μL / cell) was subcutaneously injected into the right axilla of mice. When the average tumor volume reached approximately 200 mm², the tumor was treated. 3 Mice were randomly divided into three groups (n=6): a model control group (Vihecle group), a low-dose group (CQ3196, 25 mg / kg), and a high-dose group (CQ3196, 50 mg / kg). Compound CQ3196 was diluted with 5% CMC-Na aqueous solution. Mice were administered the CQ3196 compound solution by gavage every two days, while the model control group was administered an equal volume of 5% CMC-Na aqueous solution by gavage for 12 days. Mice were observed for their condition, and tumor volume and mouse weight were monitored daily. Tumor volume (V) was calculated using the formula: V = L × W 2 / 2 (L is tumor length; W is tumor width). Animals were sacrificed 6 hours after the last administration, tumors were dissected and collected, and tumor tissue was preserved at -80°C for Western blot analysis.

[0553] The results showed that gavage administration of 50 mg / kg significantly inhibited tumor growth, with a tumor growth inhibition index (TGI) of 62.3%, indicating that compound 30 (CQ-3196) had good tumor-suppressive activity in rats. Furthermore, no significant weight loss was observed throughout the experiment, suggesting good tolerability of the drug (Figure 1).

[0560] HGC-27 and AGS cells were seeded into 12-well plates (5 × 10⁶ cells / well). 4 In a cell / cell assay, different concentrations of compound CQ3196 dissolved in DMSO were added to the drug-treated group, while an equal volume of DMSO was added to the negative control group. Cells were incubated for 4 hours, with three replicates for each concentration. Cells were then washed twice with PBS to remove cells that had lost their adhesion ability. 1 mL of 4% paraformaldehyde was added, and the cells were fixed at room temperature for 30 min. After fixation, 1 mL of 0.1% violet staining solution was added, and the cells were stained at room temperature for 20 min. Residual violet staining solution was then washed away with water, and the cells were air-dried and photographed under an inverted microscope (10x magnification). Cell counts were then performed using ImageJ software.

[0561] The results showed that compound 30 (CQ-3196) significantly reduced cell adhesion in HGC-27 and AGS cells at 300 nM and 1000 nM (Figure 3).

The next day, different concentrations of compound CQ3196 dissolved in DMSO were added to the culture medium, and the negative control group was added with an equal volume of DMSO. The plates were then incubated for another 48 h. After incubation, suspended and adherent cells were collected from the 6-well plates, centrifuged at 1000 rpm for 5 min, the supernatant was discarded, and the cells were resuspended in PBS. 200 μL of cell suspension from each group was transferred to single-labeled tubes containing 7-AAD and AV. 100 μL of 1X Binging Buffer was added to each group to resuspend the cells. 2.5 μL of Annexin-V and 2.5 μL of 7-AAD were added to each group, and the reaction was carried out at room temperature in the dark for 15 min. After 15 min, 400 μL of 1X Binging Buffer was added, the plates were transferred to ice, protected from light, and analyzed.

[0565] The results showed that compound 30 (CQ3196) induced apoptosis in HGC-27 and AGS cells in a dose-dependent manner (Figure 4).
