Abstract
Description
A pyrimidineamine NUAK inhibitor and its preparation method and use
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to Chinese patent application No. 202310860161.7 filed on July 13, 2023, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This invention belongs to the field of small molecule compounds, specifically to a pyrimidineamine-based NUAK inhibitor, its preparation method, and use. By inhibiting NUAK1 / NUAK2, the compound can be used to prevent or treat the following diseases: neuropsychiatric disorders, metabolic diseases, tumors, visceral fibrosis, skin fibrosis, or to alleviate scarring after trauma and surgery. Background Art
[0004] Protein kinases are a group of important functional proteins involved in regulating cellular metabolism, polarity, growth, division, and differentiation. The human genome encodes over 500 protein kinases, which transfer phosphate groups from ATP (adenosine triphosphate) to specific serine, threonine, or tyrosine residues on substrate proteins, thereby phosphorylating them. Most protein kinases are serine / threonine kinases, while there are fewer than 100 tyrosine kinases. Adenosine monophosphate-activated protein kinase (AMPK) belongs to the serine / threonine kinases (STKs) and is a key regulator of cellular energy homeostasis in mammals. It regulates glucose and lipid metabolism, cell proliferation, and cell polarity by sensing changes in the intracellular AMP (adenosine monophosphate) / ATP or ADP (adenosine diphosphate) / ATP ratios in response to metabolic stress (such as hypoxia and heat shock), thus regulating glucose and lipid metabolism, cell proliferation, and cell polarity. It is considered a metabolic sensor protein. AMPK is highly conserved in evolution and is a heterotrimeric protein composed of an α subunit containing a kinase domain (KD), and β and γ subunits that regulate kinase activity. The γ subunit contains four CBS functional domains (Cystathionine-β-synthase (CBS) domains), which are responsible for detecting changes in the AMP / ATP and ADP / ATP ratios in the cell (Hardie DG, Trends in Cell Biology. 2016, 26: 190).
[0005] AMPK dysfunction can lead to a variety of diseases such as obesity, diabetes, inflammatory diseases and tumors, so the body's regulation of AMPK function is very critical. First, the activation of AMPK requires upstream kinases to phosphorylate the threonine (T172) at position 172 of its α subunit. Currently, there are three known upstream kinases of AMPK: liver kinase B1 (LKB1), calcium ion / calmodulin-dependent protein kinase 2 (Ca2+), and AMPK-dependent protein kinase 2 (CMP-2). 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 T172 site, three protein phosphatases are known to inhibit AMPK activity by removing the phosphate group on T172, including protein phosphatase 2A (PP2A), protein phosphatase 2C (PP2C), and magnesium / manganese-dependent protein phosphatase 1E (Mg / Mn-dependent protein phosphatase 1E). 2+ - / Mn 2+ -dependent protein phosphatase 1E, PPM1E). When cells are in a low-energy state (high AMP / ATP or ADP / ATP ratio), the α subunit KD and γ subunit of AMPK are tightly cross-linked, and the β subunit is myristoylated, ensuring that the protein phosphatase cannot access the T172 site and remains activated. When cells are in a high-energy state, the KD and γ subunits are loosened, exposing T172 to the phosphatase and causing AMPK inactivation (Steinberg GR, Nature Reviews Drug Discovery. 2019, 18:527).
[0006] In addition to the upstream kinases and protein phosphatases that activate and inactivate AMPK, a class of AMPK-related kinases (ARKs) also participate in regulating AMPK function. Currently, there are 12 ARKs (BRSK1, BRSK2, NUAK1, NUAK2, QIK, QSK, SIK, MARK1, MARK2, MARK3, MARK4, and MELK). All are serine / threonine protein kinases. The kinase domains of ARKs share high homology with the α subunit of AMPK. With the exception of MELK, all ARKs can be activated by LKB1. Their kinase activation phosphorylation site is equivalent to T172 of AMPK. Functionally, all ARKs participate in the regulation of cellular metabolism, proliferation, and polarity. However, unlike AMPK, ARKs cannot be directly regulated by the intracellular AMP / ATP ratio because they possess no regulatory subunits (Bright NJ, Acta Physiologica. 2009, 196:15).
[0007] ARKs are further divided into several ARK subfamilies due to differences in protein structure and functional characteristics. 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 members are approximately 55% homologous. Based on the amino acid sequences, the estimated molecular weights of NUAK1 and NUAK2 are 76 and 69 kDa, respectively. Their protein structures are very similar, with a kinase domain at the amino terminus and a ubiquitin-associated domain at the carboxyl terminus. It is currently unclear whether NUAK is also a heterotrimeric structure like AMPKs. NUAK1 and NUAK2 are expressed in most tissues, with NUAK1 expression significantly higher in organs and tissues such as the brain, skin, muscle, upper digestive tract, and endocrine system than in other parts of the body. NUAK2 expression is highest in the digestive tract, female reproductive system, skin, bone, brain, and endocrine system, with NUAK2 expression showing greater tissue specificity. It is worth noting that NUAK1 and other ARKs and AMPK proteins are primarily distributed in the cytoplasm, while NUAK2 is primarily distributed in the nucleus. There are also indications that NUAK2 acts as a transcriptional regulator in the expression of genes associated with metabolic stress (Sun X, J of Molecular Endocrinology. 2013, 51: R15).
[0008] As serine / threonine protein kinases, NUAK1 and NUAK2 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), which regulates actin cytoskeletal organization. NUKA2 phosphorylates the Hedghog signaling pathway transcription factor Gli3, FoxO1, kinesin light chain 1 (KLC1), and Rho GDP dissociation inhibitor α (Rho GDIα).
[0009] The functional regulation of NUAK1 and NUAK2 involves multiple intracellular signaling systems. Besides being activated by LKB1 phosphorylation (T211, equivalent to T172 in AMPK) and calcium / PKC activation, NUAK1 is the only member of the AMPK-related protein family that can be activated by Akt. Increased NUAK1 activity is also observed in response to activation of growth factor signaling pathways, such as insulin-like growth factor 1 (IGF1). NUAK1 activity is also enhanced during skeletal muscle contraction. Both NUAK1 and NUAK2 are activated by LKB1 (T211 / NUAK1, T208 / NUAK2, equivalent to T172 in AMPK), but NUAK2 can also undergo autophosphorylation. NUAK2 interacts with ubiquitin-specific protease 9 (USP9X), a deubiquitinating enzyme on the X chromosome, to maintain NUAK2 activity. In different cells, stimuli such as low osmotic pressure, DNA damage, oxidation, and malnutrition can lead to the activation of NUAK2. NUAK2 activation is also seen in the contraction of skeletal muscle cells (Brooks D, Data in Brief. 2022, 43:108482).
[0010] Numerous studies have shown that NUAK plays a crucial role in the pathogenesis of metabolic diseases, tumors, neurodegenerative diseases, and fibrotic disorders. Homozygous knockout of NUAK1 and NUAK2 in mice generally leads to embryonic lethality. NUAK1 heterozygous deletion in mice leads to dysplasia of the body and neural tissues (such as the cerebral cortex and peripheral neurons). Heterozygous mutations in human NUAK1 are associated with autism spectrum disorders (ASD), cognitive deficits, attention deficit / hyperactivity disorder (AD / HD), and schizophrenia. NUAK2 gene deletion in humans leads to anencephaly, a severe neural tube defect that causes fetal developmental defects. Its mechanism is related to the functional loss of YAP (Bonnard C, J Exp Med. 2020, 217:e20191561). Skeletal muscle cell-specific knockout of the NUAK1 gene can prevent subclinical diabetes induced by a high-fat diet; the phenotype of NUAK2 heterozygous deletion mice is similar to a series of clinical manifestations of human type 2 diabetes accompanied by obesity, which may be related to an imbalance in the cellular autophagy mechanism (Bennison SA, Cellular Signaling. 2022, 100: 110472; Blazejewski SM, Scientific Reports. 2011, 11: 8156).
[0011] NUAK1 activation by Akt and other protein kinases promotes tumor cell survival in energy-deficient environments and protects tumor cells from apoptosis. NUAK2 also inhibits TNFα- and CD95-induced apoptosis through similar mechanisms. Furthermore, activated NUAK1 promotes tumor cell invasion and metastasis by upregulating matrix metalloproteinases (MMPs), while NUAK2 participates in tumor metastasis by enhancing tumor cell activity (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). Numerous lines of evidence suggest that NUAK1 and NUAK2 play a role in tumor formation and metastasis. Compared to NUAK1, NUAK2 has a stronger role in promoting tumor formation and metastasis. Therefore, NUAK2 inhibitors are more likely to become new targeted anti-tumor drugs than NUAK1 inhibitors.
[0012] Recent studies have shown that NUAK plays a key role in the development of tissue fibrosis through interaction with the transforming growth factor-β (TGF-β) signaling pathway. First, TGF-β upregulates NUAK1 and NUAK2 gene transcription in various epithelial cells, such as keratinocytes and human dermal fibroblasts, while inactivation of MAPK (ERK1 / 2 and p38) signaling inhibits TGF-β-dependent NUAK2 expression. Furthermore, NUAK2 inhibits the intracellular degradation of SMAD3 by binding to the crosslinking domain and MH2 domain of the TGF-β intracellular signaling mediator SMAD3. A similar mechanism also exists between NUAK2 and TβRI. TGF-β-induced gene expression of pro-fibrotic molecules such as fibronectin (FN), plasminogen activator inhibitor 1 (PAI1), and tissue inhibitor of metalloproteinase-1 (TIMP1) depends on the presence of NUAK2, which shows that NUAK2 promotes the occurrence of fibrosis. Studies have also shown that NUAK1 promotes renal, lung, and liver fibrosis by upregulating the TGF-β and YAP signaling pathways. In animal experiments, inhibiting NUAK1 can reduce scars caused by new trauma and old scar tissue (Gill MK, Nature Communications. 2018.9:3510). Interestingly, studies have found that the expression of the gene encoding FN is upregulated in keratinocytes with NUAK1 knockout genes. NUAK1 may affect TGF-β signaling through a negative feedback mechanism, thereby inhibiting fibrosis (van de Vis RAJ, Cancers. 2021, 13:3377). In general, inhibiting NUAK may effectively inhibit the fibrosis process of participating tissues and organs.
[0013] Because kinases have long been ideal targets for small molecule drugs based on their structure and function, and NUAK1 and NUAK2 are involved in the pathogenesis of various diseases, several NUAK inhibitors are currently in early stages of development, but their efficacy and safety remain uncertain (Banerjee S, The Biochemical Journal. 2014, 457:215). Therefore, the development of NUAK-selective inhibitors and NUAK1 / 2 dual-target inhibitors has the potential to provide innovative treatments for neuropsychiatric disorders (such as Parkinson's disease and Alzheimer's disease), metabolic diseases (such as diabetes, hyperlipidemia, and obesity), tumors (such as liver cancer, leukemia, lymphoma, and tumor metastasis), visceral fibrotic diseases (such as cirrhosis, renal fibrosis, pulmonary fibrosis, and myocardial sequelae), and skin fibrotic diseases (such as scleroderma, keloids, and hypertrophic scars, or simply to alleviate scarring after trauma and surgery). The development of a new generation of NUAK inhibitors has enormous potential for clinical application.

[0241] Test example: Enzyme activity inhibition assay of NUAK1 / NUAK2 kinase inhibitors
[0242] The inhibitory effect of the pyrimidine amine small molecules involved in this application on the NUAK1 and NUAK2 kinases was determined using a kinase activity assay based on P81 filter paper combined with hotspot technology (Nat Biotechnol. 2011, 29: 1039), which is briefly described as follows:
[0243] The assay buffer system contained 20 mM Hepes (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.01% Brij35 (L23 polyoxyethylene lauryl ether), 0.02 mg / ml BSA (bovine serum albumin), 0.1 mM Na3VO4, 2 mM DTT, and 1% DMSO.
[0244] Test steps:
[0245] 1. Prepare a 20 μM substrate solution using freshly prepared assay buffer. The substrate is a CHKtide polypeptide fragment (Sanchez Y. Science. 1997, 277: 1497-1501).
[0246] 2. Add kinase and mix gently (the final concentration of NUAK1 is 10 nM; the final concentration of NUAK2 is 50 nM);
[0247] 3. Add the test compound dissolved in 100% DMSO to the above kinase reaction mixture using acoustic pipetting technology (Echo550; nanoliter) and incubate at room temperature for 5 minutes;
[0248] 4. Join 33 P-labeled ATP (unlabeled ATP / labeled ATP ratio of 25:1 or 2.5:1);
[0249] 5. Incubate at room temperature for 2 hours;
[0250] 6. Detect kinase activity using P81 filter paper combined with hotspot technology.
[0251] The IC of the test compound against NUAK1 / NUAK2 was calculated according to the above assay. 50 , see Table 1 for specific results.
[0252] IC 50 Calculations were made using the formula derived from a sigmoidal dose-response curve (variable slope):
[0253] Y = Bottom + (Top - Bottom) / (1 + 10^((LogEC50 - X) * slope, where X is the Log value of the compound concentration and Y is the response (inhibition rate of kinase activity). Y rises from the bottom to the top along the S-shaped curve as the concentration increases.
