Description

[0001] The present disclosure claims priority to the Chinese Patent Application 202011483614.1 filed to the China National Intellectual Property Administration (CNIPA) on December 16, 2020 and entitled "COMPOUND, PREPARATION METHOD THEREOF, AND USE THEREOF IN PREPARATION OF ANTI-CANCER DRUG".TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of pharmacy, and in particular to a 2H-pyrazolo[3,4-d]pyrimidine derivative, a preparation method thereof, and use thereof in the preparation of an anti-cancer drug.BACKGROUND ART

[0003] Fibroblast growth factor receptors (FGFRs) are members of the receptor tyrosine kinase (RTK) family and are receptor protein tyrosine kinases (RPTKs), including four highly-conserved transmembrane tyrosine kinases: FGFR1, FGFR2, FGFR3, and FGFR4. A signaling pathway of FGFR is that a ligand binds to a receptor to induce FGFR dimerization, thereby causing cascade activation of downstream signaling pathways such as Ras-MAPK, PI3K-Akt, STAT, and PLCy. FGFRs play important roles in a variety of cell functions, such as cell proliferation and differentiation, and biological processes including development, angiogenesis, homeostasis, and wound repair. According to research surveys (1-3)< , 7.1% of cancer patients have FGFR abnormalities. For example, the FGFR1 amplification occurred most in squamous non-small cell lung cancer (NSCLC) patients with a proportion of 20%, which was 10% in breast cancer patients, 5% in ovarian cancer patients, and 3% in bladder cancer patients. Currently, FGFR2 mutations have been found in gastric cancer (10%), endometrial cancer (12%), squamous NSCLC (5%), and triple-negative breast cancer (TNBC) (4%); and FGFR3 mutations are well known in bladder cancer (50% to 60%) and myeloma (15% to 20%). Aberrant FGF19 / FGFR4 signaling is closely associated with hepatocellular carcinoma (HCC). Therefore, the development of a novel selective FGFR inhibitor to block the FGF / FGFR signaling pathway presents a promising therapeutic strategy for FGFR-associated cancer (4-5)< .

[0004] Researchers are committed to developing an FGFR inhibitor as a novel anti-cancer agent for the treatment of FGFR-associated cancer. Several multi-targeted tyrosine kinase inhibitors (TKIs) are initially used to treat FGFR abnormality-associated cancer (6)< , such as dovitinib (TKI-258), lucitanib (E-3810) (7)< , nintedanib (BIBF-1120) (8)< , and ponatinib (AP-24534) (9)< . These FGFR inhibitors developed early are non-selective (10)< . Subsequently, several TKIs selective for FGFR with various scaffolds are developed. Some TKIs are currently in different stages of clinical research, such as AZD-4547 (phase III) (11)< , BGJ-398 (phase II) (12)< , LY-2874455 (phase II) (13)< , and JNJ-42756493 (phase II) (14)< , and these selective FGFR inhibitors are ATP-competitive inhibitors that bind to an active form of FGFR. In addition, FGFR inhibitors developed by many pharmaceutical chemistry laboratories have been reported. (15-21)<

[0005] AOLI WANG et al. (22)< discloses: on the basis of Ibrutinib's core pharmacophore, which was moderately active to EGFR T790M mutant, we discovered novel epidermal growth factor receptor (EGFR) inhibitor compound 19 (CHMFL-EGFR-202), which potently inhibited EGFR primary mutants (L858R, del19) and drug-resistant mutant L858R / T790M. Compound 19 displayed a good selectivity profile among 468 kinases / mutants tested in the KINOMEscan assay (S score (1) = 0.02). In particular, it did not exhibit apparent activities against INSR and IGF1R kinases. The X-ray crystal structure revealed that this class of inhibitors formed a covalent bond with Cys797 in a distinct "DFG-in-C-helix-out" inactive EGFR conformation. Compound 19 displayed strong antiproliferative effects against EGFR mutant-driven nonsmall cell lung cancer (NSCLC) cell lines such as H1975, PC9, HCC827, and H3255 but not the wild-type EGFR expressing cells. In the H1975 and PC9 cell-inoculated xenograft mouse models, compound 19 exhibited dose-dependent tumor growth suppression efficacy without obvious toxicity. Compound 19 might be a potential drug candidate for EGFR mutant-driven NSCLC.

[0006] WOLLE PATRIK et al. (23)< discloses: pyrazolopyrimidines are well-established as covalent inhibitors of protein kinases such as the epidermal growth factor receptor or Bruton's tyrosine kinase, and we recently described their potential in targeting mitogen-activated protein kinase kinase 7 (MKK7). Herein, we report the structure-activity relationship of pyrazolopyrimidine-based MKK7 inhibitors and solved several complex crystal structures to gain insights into their binding mode. In addition, we present two structures of apo-MKK7, exhibiting a DFG-out and an unprecedented DFG-in / Leu-in conformation.

[0007] YIN YUAN et al. (24)< discloses: Janus kinases (JAKs) regulate various cancers and immune responses and are targets for the treatment of cancers and immune diseases. A new series of 1H-pyrazolo[3,4-d]pyrimidin-4-amino derivatives were synthesized and optimized by introducing a functional 3,5-disubstituted-1H-pyrazole moiety into the C-3 moiety of pyrazole template, and then were biologically evaluated as potent Janus kinase 2 (JAK2) inhibitors. Among these molecules, inhibitors 11f, 11g, 11h and 11k displayed strong activity and selectivity against the JAK2 kinase, with IC50 values of 7.2 nM, 6.5 nM, 8.0 nM and 9.7 nM, respectively. In particular, the cellular inhibitory assay and western blot analysis further support the JAK2 selectivity of compound 11g also in cells. Furthermore, compound 11g also exhibited potent inhibitory activity in lymphocytes proliferation assay and delayed hypersensitivity assay. Taken together, the novel JAK2 selective inhibitors discovered in this study may be potential lead compounds for new drug discovery via further development of more potent and selective JAK2 inhibitors.

Methods for the preparation of the compounds are disclosed. Also disclosed are pharmaceutical compositions that include the compounds. Methods of using the Btk inhibitors are disclosed, alone or in combination with other therapeutic agents, for the treatment of autoimmune diseases or conditions, heteroimmune diseases or conditions, cancer, including lymphoma, and inflammatory diseases or conditions.

[0009] ENGEL JULIAN et al. (25)< discloses reversible epidermal growth factor receptor (EGFR) inhibitors prompt a beneficial clinical response in non-small cell lung cancer patients who harbor activating mutations in EGFR. However, resistance mutations, particularly the gatekeeper mutation T790M, limit this efficacy. Here, we describe a structure-guided development of a series of covalent and mutant-selective EGFR inhibitors that effectively target the T790M mutant. The pyrazolopyrimidine-based core differs structurally from that of aminopyrimidine-based thirdgeneration EGFR inhibitors and therefore constitutes a new set of inhibitors that target this mechanism of drug resistance. These inhibitors exhibited strong inhibitory effects toward EGFR kinase activity and excellent inhibition of cell growth in the drug-resistant cell line H1975, without significantly affecting EGFR wild-type cell lines. Additionally, we present the in vitro ADME / DMPK parameters for a subset of the inhibitors as well as in vivo pharmacokinetics in mice for a candidate with promising activity profile.

[0010] YUMING WANG et al. (26)< discloses: Fibroblast growth factor receptors (FGFR1-4) are promising therapeutic targets in many cancers. With the resurgence of interest in irreversible inhibitors, efforts have been directed to the discovery of irreversible FGFR inhibitors. Currently, several selective irreversible inhibitors are being evaluated in clinical trials that could covalently target a conserved cysteine in the P-loop of FGFR. In this article, we used a structure-guided approach that is rationalized by a computer-aided simulation to discover the novel and irreversible pan-FGFR inhibitor, 9g, which provided superior FGFR in vitro activities and decent selectivity over VEGFR2 (vascular endothelia growth factor receptor 2). In in vivo studies, 9g displayed clear antitumor activities in NCI-H1581 and SNU-16 xenograft mice models. Additionally, the diluting method confirmed the irreversible binding of 9g to FGFR.

[0013] HE Linhong et al. (27)< discloses: Bruton's tyrosine kinase (Btk) is a Tec family kinase with a well-defined role in the B cell receptor (BCR) and Fc γ receptor (FcR) signaling pathways, which makes it a uniquely attractive target for the treatment of autoimmune diseases, such as rheumatoid arthritis (RA). We reported a series of compounds bearing 7H-pyrrolo [2,3-d]pyrimidin-4-amine scaffold that potently inhibited Btk in vitro. Analysis of the structure-activity relationships (SAR) and drug-like profiles led to the discovery of the optimal compound B16. B16 preferentially inhibited Btk (IC50 = 21.70 ± 0.82 nM) over closely related kinases with moderate selectivity. Cell-based tests also confirmed that B16 significantly inhibited Btk Y223 autophosphorylation and PLC γ 2 Y1217 phosphorylation. MTT revealed that B16 displayed weak suppression against normal LO2, HEK293 and THP-1 cell lines with IC50 values over 30 µM. Moreover, B16 showed very weak potential to block the hERG channel (IC50 = 11.10 µM) in comparison to ibrutinib (IC50 = 0.97 µM). Owing to its favorable physicochemical properties (ClogP = 2.53, aqueous solubility ≈ 0.1 mg / mL), pharmacokinetic profiles (F = 49.15%, t1 / 2 = 7.02 h) and reasonable CYP450 profile, B16 exhibited potent anti-arthritis activity and similar efficacy to ibrutinib in reducing paw thickness in CIA mice. In conclusion, B16 is a potent, selective and durable inhibitor of Btk and has the potential to a safe and efficacious treatment for arthritis.

[0131] In the present disclosure, the homogeneous time-resolved fluorescence (HTRF) technology was used to evaluate an inhibitory effect of a compound on the four subtypes FGFR1, FGFR2, FGFR3, and FGFR4. FGFR1, FGFR2, FGFR3, and FGFR4 prokaryotic expression vectors were first constructed; and when the prokaryotic expression vectors were identified as correct, FGFR proteins were expressed and purified on a large scale in an Escherichia coli (E. coli) system, and protein concentrations were determined. Resulting proteins were stored in aliquots. Before an enzyme activity test was started, cisbio HTRF KinEA (62TK0PEB) was used to predilute each component required in an enzyme activity system with an enzyme activity buffer to a required working concentration. A 384-well plate (66PL384025) was prepared, 5 µL of a protein solution, 1 µL of a compound, and 2 µL of a substrate were added to each well, and 2 µL of ATP was finally added to initiate a reaction. Three parallel experiments were set for each concentration. In the blank control group, 1 µL of the compound was replaced with 1 µL of dimethyl sulfoxide (DMSO); and in the positive control group, the positive drug AZD4547 was used instead, and the other conditions remained unchanged. The 384-well plate was sealed and incubated at room temperature for about 1 h. After the incubation was completed, 5 µL of a lanthanide-labeled phosphorylated substrate antibody (a donor) and 5 µL of a streptavidin-labeled XL665 (a receptor) were added to each well to stop the reaction, and the plate was further incubated at room temperature for about 1 h in the dark. Finally, the TECAN infinite M1000PRO multi-function microplate reader was used to detect a fluorescence signal, an inhibition rate was calculated, and an IC50 value was fitted with GraphPad Prism 7.0.

[0132] Results showed that the compounds 1 to 40 could inhibit the protein activity of FGFR1 / 2 / 3 / 4 to varying degrees.

[0133] In the present disclosure, the compounds 10 and 36 were selected, and the methyl thiazolyl tetrazolium (MTT) colorimetric method was used to evaluate the proliferation inhibition effects of the compounds 10 and 36 on various tumor cells. Tumor cells in a logarithmic growth phase were collected through trypsinization and resuspended in 1 mL of a fresh medium, and a small amount of a resulting suspension was taken, diluted, and subjected to cell counting with a hemocytometer. According to the cell growth rate, tumor cells were inoculated into a 96-well plate at a density of 3,000 cells / well to 5,000 cells / well, and then cultivated in an incubator for 24 h. The tumor cells were treated with the compounds 10 and 36 at 8 concentrations, with three replicate wells for each concentration, and then incubated for 96 h. After the incubation was completed, 10 µL of an MTT solution (5 mg / mL) was added to each well, and the plate was tapped for thorough mixing and then further incubated in an incubator for 3 h to 4 h. After the incubation was completed, the liquid in the well plate was carefully pipetted and removed, and then 100 µL of a DMSO solution was added to each well. Programs of a microplate reader were set to determine the absorbance values at 490 nm and 570 nm respectively, a proliferation inhibition rate at each concentration was calculated according to a formula, and the Graphpad Prism 7 software was finally used for data processing to calculate IC50.

[0134] The results (Table 1) showed that the compounds 10 and 36 significantly inhibited the proliferation of human squamous cell lung carcinoma cell NCI-H1581 (FGFR1 amplification) and human gastric cancer cell SNU-16 (FGFR2 amplification) and inhibited the proliferation of human hepatoma cell SK-hep-1 (FGFR4 amplification) to some degree, but exhibited no obvious inhibitory effect on tumor cells with normal FGFR expression, indicating that the compounds 10 and 36 had strong selectivity.

[0135] To further elucidate the influence of the compounds 10 and 36 on FGF / FGFR signaling, the influence of the compounds on FGFR and downstream signaling protein phosphorylation was verified by western blot (WB). Each of human squamous cell lung carcinoma cells NCI-H1581 and human gastric cancer cells SNU-16 in a logarithmic growth phase were collected through trypsinization and resuspended in 1 mL of a fresh medium, and a small volume of a resulting tumor cell suspension was taken, diluted, and subjected to cell counting with a hemocytometer. A corresponding volume of the tumor cell suspension was taken and inoculated into a 6-well plate at a density of 3 × 10 5< cells / well, and cultivated in an incubator for 24 h. After the cells were completely adherence, the used medium was pipetted and removed, fresh media with the compounds 10 and 36 at different concentrations were added, and the plate was incubated in an incubator for 12 h. After the incubation was completed, a culture supernatant was pipetted and removed, and the plate was washed three times with a pre-cooled 1X PBS solution to completely pipet and remove the residual solution; 60 µL of an RIPA lysis buffer was added to each well, and cells were gently scraped off with a cell scraper; a resulting lysis buffer was transferred to a 1.5 mL EP tube, subjected an ice bath for 10 min, and centrifuged at 14,000 rpm for 10 min, a resulting supernatant was pipetted into a new 1.5 mL EP tube, and a small amount of the supernatant was pipetted for protein content determination; and a corresponding volume of 5 X loading buffer was added to the remaining supernatant, and a resulting mixture was vortexed for thorough mixing and subjected a metal bath at 100°C for 10 min. According to a determined protein content, a corresponding loading amount was calculated at 30 µg of protein per well. Proteins were isolated by 8% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), the isolated proteins were transferred to a polyvinylidene fluoride (PVDF) membrane, and stained with Ponceau S, and the PDVF membrane with proteins was cut according to a molecular weight of a target protein, rinsed with a 1X TBST solution to remove Ponceau S, and blocked with 5% skimmed milk powder for 30 min. The PDVF membrane was washed three times with a 1X TBST solution, a PDVF membrane with the target protein band was placed in an incubation box, a corresponding primary antibody incubation solution was added, and the PDVF membrane was incubated at 4°C overnight. After the primary antibody incubation was completed, the membrane was washed three times with a 1X TBST solution, a corresponding secondary antibody incubation solution was added, and the membrane was incubated at room temperature for 1.5 h. After the incubation was completed, the membrane was washed three times with a 1X TBST solution and subjected to color development with a hypersensitive horseradish peroxidase (HRP) chemiluminescence kit.

[0136] As shown in FIG. 1 and FIG. 2, the compounds 10 and 36 not only significantly inhibited the phosphorylation of FGFR1 in NCI-H1581 cells and the phosphorylation of FGFR2 in SNU-16 cells, but also inhibited the activation of downstream PLCγ, AKT, and ERK in a dose-dependent manner. In a word, the compounds 10 and 36 can strongly inhibit FGF / FGFR and downstream signaling pathways in vitro.Example 44 Significant inhibition of the compounds 10 and 36 on tumor growth in mice

[0137] In order to evaluate an anti-tumor effect of the compounds 10 and 36 in vivo, a mouse subcutaneous xenograft model was established with human squamous cell lung carcinoma cells NCI-H1581 with high FGFR1 expression. Cells in a logarithmic growth phase were collected through trypsinization, washed three times with 1X PBS. A resulting cell precipitation was diluted to 1 × 10 8< cells / mL with a resuspending solution (1640 medium : Matrigel = 1:1), and inoculated into inferior extremity of armpits of anterior limbs of 5-6 week-old female BALB / c Nude mice at 5 × 10 6< cells / mouse. When a tumor volume grew to 50 mm 3< to 100 mm 3< , the mice were randomly divided into three groups (control group, 50 mg / kg, and 100 mg / kg), with 6 mice in each group. The compound 10 was administered orally every day, and the compound 36 was intraperitoneally injected every day. The tumor volume and mouse body weight were measured. The mice was treated after 26 d of administration, that a tumor tissue was dissected and fixed in a formalin solution for later use.

[0138] As shown in FIG. 3 and FIG. 4, the compounds 10 and 36 inhibited the proliferation of NCI-H1581 cells in mice in a dose-dependent manner, with an inhibition rate of 72% in the highdose group; inhibited the phosphorylation activation of FGFR1 in a tumor tissue; and did not lead to an obvious weight loss, indicating that the compounds 10 and 36 were well tolerated in vivo at all doses.

[0139] In conclusion, the present disclosure optimizes 2H-pyrazolo[3,4-d]pyrimidine to obtain novel derivatives thereof (compounds 10 and 36), and the compounds 10 and 36 are served as effective and selective inhibitors for FGFR1, FGFR2, and FGFR3, which exhibit an irreversible binding effect to a target protein. The compounds are leading compounds that can not only inhibit FGF / FGFR and downstream signaling pathways thereof at low concentrations, but also exhibit significant anti-proliferation effects on the NCI-H1581 cancer cell line in vitro and in vivo. In addition, the compounds 10 and 36 show low toxicity and prominent PK properties, and are currently identified as potential drug candidates.
