Description

Technical Field

[0001] The present invention belongs to the field of small molecule compounds, and specifically relates to a pyrimidineamine NUAK inhibitor, a preparation method thereof and uses thereof. By inhibiting NUAK1 or NUAK2, the compound can be used for preventing or treating the following diseases: neuropsychiatric diseases, metabolic diseases, tumors, visceral fibrosis diseases, skin fibrosis diseases, or can be used alone to reduce trauma and postoperative scars. Background Art

[0002] Protein kinases are a group of important functional proteins involved in regulating cell metabolism, polarity, growth, division and differentiation. The human genome encodes more than 500 protein kinases, and these kinases can transfer the phosphate group on ATP (adenosine triphosphate) to specific serine, threonine or tyrosine residues of substrate proteins to phosphorylate them; most protein kinases are serine / threonine kinases, and there are less than 100 tyrosine kinases. Adenosine monophosphate-activated protein kinase (AMPK) belongs to serine / threonine kinases (STK), and is an important regulator of cellular energy homeostasis in mammals. It regulates sugar and lipid metabolism, cell proliferation and cell polarity by sensing the changes in the ratio of intracellular AMP (Adenosine monophosphate) / ATP, or ADP (adenosine diphosphate) / ATP under metabolic stress (such as hypoxia, heat shock), and can be called a metabolic sensor protein. AMPK is very conserved in evolution and is a heterotrimeric protein composed of an α subunit containing a kinase domain (KD), a β subunit and a γ subunit that regulate kinase activity. The γ subunit contains four CBS functional domains (Cystathionine-β-synthase (CBS) domains) responsible for detecting the changes in the ratio of intracellular AMP / ATP and ADP / ATP (Hardie DG, Trends in Cell Biology. 2016, 26:190).

[0003] Dysfunction of AMPK can lead to various diseases such as obesity, diabetes, inflammatory diseases and tumors. Therefore, the regulation of AMPK function by the body is very crucial. First, the activation of AMPK requires the phosphorylation of threonine (T172) at position 172 of its α subunit by upstream kinases. Currently, there are three known upstream kinases of AMPK: liver kinase B1 (LKB1), calcium / calmodulin-dependent protein kinase 2 (Ca 2+ / calmodulin-dependent PK kinase 2, CaMKK2), and transforming growth factor-β-activated kinase 1 (TAK1). Corresponding to the activation of AMPK by upstream kinases through phosphorylation of the T172 site, there are three known protein phosphatases that can inhibit the activity of AMPK by removing the phosphate group on T172, including protein phosphatase 2A (PP2A), protein phosphatase 2C (PP2C), and magnesium / manganese-dependent protein phosphatase 1E (Mg 2+ - / Mn 2+ -dependent protein phosphatase 1E, PPM1E). When the cell is in a low-energy state (high AMP / ATP or ADP / ATP ratio), the KD of the α subunit and the γ subunit of AMPK are tightly cross-linked, and at the same time, the β subunit is myristoylated, ensuring that the protein phosphatase cannot access the T172 site and remains in an active state. When the cell is in a high-energy state, the KD and γ subunit loosen, and T172 is exposed to the phosphatase, resulting in the inactivation of AMPK (Steinberg GR, Nature Reviews Drug Discovery. 2019, 18:527).

[0004] In addition to the upstream kinases and protein phosphatases of AMPK that can activate and inactivate AMPK respectively, there is also a class of AMPK-related kinases (ARKs) involved in regulating the function of AMPK. So far, a total of 12 ARKs (BRSK1, BRSK2, NUAK1, NUAK2, QIK, QSK, SIK, MARK1, MARK2, MARK3, MARK4, and MELK) have been discovered. They all belong to serine / threonine protein kinases. The kinase domains of ARKs have a high homology with the α subunit of AMPK. Except for MELK, they can all be activated by LKB1, and the phosphorylation sites for kinase activation are also equivalent to T172 of AMPK. Functionally, they are all involved in the regulation of cell metabolism, proliferation, and polarity. However, since ARKs do not have regulatory subunits like AMPK, they cannot be directly regulated by the intracellular AMP / ATP ratio (Bright NJ, Acta Physiologica. 2009, 196:15).

[0005] ARKs are further divided into several ARK subfamilies according to different protein structure and function characteristics. Among them, the NUAK (Nu(novel) and AMPK-related kinase) ARK subfamily contains two members, NUAK1 (originally named ARK5) and NUAK2 (originally named sucrose nonfermenting-like / AMPK related kinase, SNARK). The amino acid sequences of the two are approximately 55% homologous. According to the amino acid sequences, the predicted molecular weights of NUAK1 and NUAK2 are 76 and 69 kDa respectively; their protein structures are very similar. The amino terminus is the kinase domain, and the carboxyl terminus is the ubiquitin-associated domain. It is not yet clear whether NUAK is also an heterotrimeric structure like AMPKs. NUAK1 and NUAK2 are expressed in most tissues. Among them, the expression of NUAK1 in organs and tissues such as the brain, skin, muscle, upper digestive tract, and endocrine is significantly higher than other parts. The organs and tissues with the highest expression of NUAK2 are the digestive tract, female reproductive system, skin, bone, brain, and endocrine, etc. Among them, the expression of NUAK2 shows more tissue specificity. It is worth mentioning that NUAK1 and other ARKs and AMPK proteins are mainly distributed in the cytoplasm, while NUAK2 is mainly distributed in the nucleus, and there are indications that NUAK2 participates in the gene expression related to metabolic stress as a transcriptional regulator (Sun X, J of Molecular Endocrinology. 2013, 51:R15).

[0006] As serine / threonine protein kinases, NUAK1 and NUAK2 can phosphorylate a variety of protein substrates, including proteins involved in cell signaling, metabolism, cell proliferation, apoptosis, autophagy, and cytoskeletal organization. NUAK1 is known to phosphorylate AMPK, LATS1 / 2, the p53 tumor suppressor protein, and myosin phosphatase target subunit 1 (Mypt1) that regulates actin cytoskeletal organization, etc. NUKA2 can phosphorylate the transcription factor Gli3, FoxO1, kinesin light chain 1 (KLC1), and Rho GDP dissociation inhibitor α (Rho GDIα) of the Hedgehog signaling pathway, etc.

[0007] The functional regulation of NUAK1 and NUAK2 involves multiple intracellular signaling systems. In addition to being phosphorylated and activated by LKB1 (T211, equivalent to T172 of AMPK) and activated by calcium / PKC, NUAK1 is the only member of the AMPK-related protein family that can be activated by Akt. An increase in NUAK1 activity is also seen in the activation of some growth factor signaling pathways such as insulin-like growth factor 1 (IGF1), and the activity of NUAK1 is enhanced when skeletal muscle cells are in a contracted state. Both NUAK1 and NUAK2 can be activated by LKB1 (T211 / NUAK1, T208 / NUAK2, equivalent to T172 of AMPK), but NUAK2 can be autophosphorylated and activated. NUAK2 can interact with ubiquitin-specific protease 9 on the X chromosome (USP9X), which is a deubiquitinating enzyme that can maintain the activity of NUAK2. In different cells, stimuli such as low osmotic pressure, DNA damage, oxidation, and nutrient deficiency can lead to the activation of NUAK2, and the activation of NUAK2 is also seen in the contraction of skeletal muscle cells (Brooks D, Data in Brief. 2022, 43:108482).

[0008] Multiple studies have shown that NUAK plays an important role in the pathogenesis of diseases such as metabolic diseases, tumors, neurodegenerative diseases, and fibrotic diseases. Homozygous knockout of NUAK1 and NUAK2 genes in mice basically leads to embryonic death. Heterozygous deletion of NUAK1 in mice results in dysplasia of the body and nervous tissues (such as cerebral cortex and peripheral neurons). Heterozygous mutations in human NUAK1 gene are associated with autism spectrum disorders (ASD), cognitive deficits, attention deficit / hyperactivity disorder (AD / HD), and schizophrenia. Deletion of the human NUAK2 gene leads to the formation of anencephaly, a severe neural tube defect that causes fetal developmental defects, and its mechanism is related to the loss of function of YAP (Bonnard C, J Exp Med. 2020, 217:e20191561). Specific knockout of the NUAK1 gene in skeletal muscle cells can avoid subclinical diabetes induced by a high-fat diet; while the phenotypes of NUAK2 heterozygous deletion mice are similar to a series of clinical manifestations of human type 2 diabetes with obesity, and these phenomena may be related to the imbalance of the autophagy mechanism (Bennison SA, Cellular Signaling. 2022, 100:110472; Blazejewski SM, Scientific Reports. 2011, 11:8156).

[0009] Activation of NUAK1 by Akt and other protein kinases can promote the survival of tumor cells in an energy-deficient environment and protect tumor cells from apoptosis. NUAK2 also inhibits TNFα- and CD95-induced apoptosis through a similar mechanism. In addition, after activation, NUAK1 promotes the invasion and metastasis of tumor cells by upregulating matrix metalloproteinases (MMP), while NUAK2 participates in the occurrence of tumor metastasis by enhancing the motility of tumor cells (Hou X, Oncogen. 201, 30:2933; Chen Y, Cell Death and Disease. 2020, 11:712; Molina E, Cells. 10:2760; Humbert N, The EMBO Journal. 2010, 29:376). A lot of evidence shows that NUAK1 and NUAK2 play a role in tumor formation and metastasis. Compared with NUAK1, NUAK2 has a stronger effect on promoting tumor formation and metastasis. NUAK2 inhibitors should be more likely to become new targeted anti-tumor drugs than NUAK1 inhibitors.

[0010] Recent studies have shown that NUAK plays a key role in the development of tissue fibrosis through its interaction with the transforming growth factor-β (TGF-β) signaling pathway. First, TGF-β can upregulate the gene transcription of NUAK1 and NUAK2 in a variety of epithelial cells such as keratinocytes and human dermal fibroblasts, while the inactivation of the MAPK (ERK1 / 2 and p38) signaling inhibits TGF-β-dependent NUAK2 expression; in addition, NUAK2 inhibits the intracellular degradation of SMAD3 by binding to the structural cross-linking domain and MH2 domain of the intracellular signal mediator SMAD3 protein of TGF-β, and a similar mechanism also exists between NUAK2 and TβRI. The gene expression of pro-fibrotic molecules such as fibronectin (FN), plasminogen activator inhibitor 1 (PAI1), and tissue inhibitor of metalloproteinase-1 (TIMP1) induced by TGF-β depends on the presence of NUAK2, indicating that NUAK2 promotes the occurrence of fibrosis. Studies have also shown that NUAK1 promotes renal, pulmonary, and hepatic fibrosis by upregulating the TGF-β and YAP signaling pathways, and inhibiting NUAK1 in animal experiments can reduce scars caused by new wounds and old scar tissues (Gill MK, Nature Communications. 2018.9:3510). Interestingly, it was found that the gene expression of FN encoding was upregulated in NUAK1-knockout keratinocytes, and NUAK1 may inhibit fibrosis by affecting TGF-β signal transduction through a negative feedback mechanism (van de Vis RAJ, Cancers. 2021, 13:3377). Generally speaking, inhibiting NUAK may effectively inhibit the fibrosis process of tissues and organs.

[0011] Since kinases have always been ideal small-molecule drug targets in terms of structure and function, and NUAK1 and NUAK2 are involved in the occurrence of various diseases. At present, some NUAK inhibitors are in the early stage of research and development, and their effectiveness and safety remain doubtful (Banerjee S, The Biochemical Journal. 2014, 457:215). Therefore, the development of NUAK selective inhibitors and NUAK1 / 2 dual-target inhibitors is expected to provide new directions for innovative treatments for neuropsychiatric diseases (such as Parkinson's disease, Alzheimer's disease), metabolic diseases (such as diabetes, hyperlipidemia, obesity), tumors (such as liver cancer, leukemia, lymphoma, tumor metastasis), visceral fibrosis diseases (such as liver cirrhosis, renal fibrosis, pulmonary fibrosis, and sequelae of myocarditis), and skin fibrosis diseases (such as scleroderma, keloid, hypertrophic scar, or simply used to reduce scars after trauma and surgery). Developing a new generation of NUAK inhibitors has great potential clinical application value. Summary of the Invention

[0164] Test Example: Detection of Enzyme Activity Inhibition of NUAK1 / NUAK2 Kinase Inhibitor

[0165] The inhibitory activity of the pyrimidine amine small molecules involved in this application against NUAK1 and NUAK2 kinases was tested using a kinase activity assay based on the P81 filter paper binding hot spot technology (Nat Biotechnol. 2011, 29: 1039), which is briefly described as follows:

[0166] The test buffer system contains 20 mM Hepes (pH 7.5), 10 mM MgCl 2 , 1 mM EGTA, 0.01% Brij35 (L23 polyoxyethylene lauryl ether), 0.02 mg / ml BSA (bovine serum albumin), 0.1 mM Na 3 VO 4 , 2 mM DTT, 1% DMSO.

[0167] Test steps:

[0168] 1. Prepare a 20 μM substrate solution with freshly prepared test buffer. The substrate is the CHKtide polypeptide fragment (Sanchez Y. Science. 1997, 277: 1497 - 1501);

[0169] 2. Add the kinase and mix gently (the final concentration of NUAK1 is 10 nM; the final concentration of NUAK2 is 50 nM);

[0170] 3. Use acoustic liquid handling technology (Echo550; nanoliter scale) to add the test compound dissolved in 100% DMSO to the above kinase reaction mixture and incubate at room temperature for 5 minutes;

[0171] 4. Add 33 P - labeled ATP (the ratio of unlabeled ATP to labeled ATP is 25:1 or 2.5:1);

[0172] 5. Incubate at room temperature for 2 hours;

[0173] 6. Detect the kinase activity by the P81 filter paper binding hot spot technology.

[0174] Calculate the IC 50 of the test compound against NUAK1 / NUAK2. For the specific results, see Table 1.

[0175] IC 50 The calculation uses the formula obtained from a sigmoidal dose - response curve (variable slope):

[0176] Y = Bottom + (Top - Bottom) / (1 + 10^((LogEC50 - X)*slope)), where X is the Log value of the compound concentration, Y is the response (inhibition rate of kinase activity), and Y increases from bottom to top along the sigmoidal curve as the concentration increases.
