Description

Technical Field

[0001] This invention belongs to the field of medicinal chemistry. Specifically, it relates to substituted fused bicyclic compounds and their applications as therapeutically effective kinase inhibitors and anticancer drugs. Background Technology

[0002] AMPK (Adenosine 5'-monophosphate (AMP)-activated protein kinase) is an AMP-dependent protein kinase, a serine / threonine protein kinase, which plays an important role in many aspects of cellular energy metabolism, glucose and cholesterol metabolism, and cell proliferation (Tiziana et al., 2015; Vincent et al., 2015). AMPK activity is mainly regulated by the intracellular AMP / ATP ratio (Sanz P et al., 2008). When the intracellular ATP concentration decreases, the increased 5'-AMP activates AMPK. AMPK has a heterotrimeric structure, consisting of a catalytic subunit α and two regulatory subunits β and γ. One piece of evidence linking AMPK to tumorigenesis is that AMPK is a substrate of the tumor suppressor kinase LKB1. Currently, 12 AMPK-related kinases with structures similar to the AMPK α subunit have been identified, including BRSK1, BRSK2, NUAK1, NUAK2, QIK, QSK, SIK, MARK1, MARK2, MARK3, MARK4, and MELK. All of these kinases, except MELK, can be specifically phosphorylated and activated by LKB1 at threonine position 172, which corresponds to the catalytic subunit of AMPK (Sun et al., 2013).

[0003] NUAK1 (also known as AMPK-related protein kinase 5 or ARK5) and NUAK2 (also known as NUAK family SNF1-like kinase 2 or SNARK) are members of the AMPK-related protein kinase family and share a high degree of structural similarity. Structurally, they are similar to the α-catalytic subunit of AMPK and both contain a ubiquitin-binding domain at the C-terminus of their catalytic region (Bright NJ et al., 2009), which is essential for the phosphorylation and activation of LKB1. Amino acid sequence analysis showed that human NUAK1 and NUAK2 share an overall homology of 55% (Suzuki et al., 2003).

[0004] NUAK1, a member of the AMPK-related kinase family discovered by Suzuki et al. in 2003, consists of 661 amino acids and has a molecular weight of 74 kDa. NUAK1 is expressed in the heart, kidney, liver, brain, and skeletal muscle, and is highly expressed in various cancer cells, including multiple myeloma. Studies have shown that NUAK1 is associated with the AKT signaling pathway, particularly with IGF-induced cell migration and invasion (Kusakai et al., 2004). NUAK1 is highly relevant to cancer cell generation and survival, inhibiting tumor cell apoptosis induced by glucose starvation and factors such as cytokines and TNFα (Atsushi et al., 2003), and is a major factor in AKT-dependent tumor survival and metastasis. In summary, NUAK1 is highly expressed in tumor cells such as breast cancer (Liu F et al., 2013), liver cancer (Cui J et al., 2013), and pancreatic cancer (HUANG X et al., 2014), playing an important role in tumor metastasis and invasion, making it a potential therapeutic target for cancer.

[0005] NUAK2 is the fourth member of the AMPK-associated protein kinase family (Dmytro et al., 2012) and possesses autophosphorylation capabilities. The human NUAK2 gene is located on chromosome 1q32.1, consists of 628 amino acids, and has a molecular weight of 69 kDa. NUAK2 is primarily distributed in the cell nucleus and can be activated in response to cellular and environmental stresses, forming part of the cellular stress response. The activation and regulatory mechanisms of NUAK2 are broadly similar to those of AMPK (Bekri et al., 2014), with its activity mainly regulated by the intracellular AMP / ATP ratio, such as glucose deprivation or chemical ATP production (Waise et al., 2019; Rune et al., 2009). The death receptor CD95 induces apoptosis in many tissues, and studies have reported that NUAK2 is one of the CD95 regulatory genes, inducing apoptosis through a TNF-α and NF-κB-mediated mechanism (Zagorska et al., 2010). Studies have found that NUAK2 is highly expressed in various tumor cells, and the growth and survival of melanoma are closely related to NUAK2 kinase. Knocking out NUAK2 and inhibiting the PI3K pathway can effectively control CDK2 expression. CDK2 inactivation specifically inhibits the proliferation of melanoma cells with low NUAK2 expression and PTEN deficiency, suggesting that CDK2 blockade can treat PTEN-deficient melanoma by interfering with NUAK2 (Namiki et al., 2015).

[0006] The activity regulation of NUAK1 is similar to that of AMPK. Its catalytic domain contains a highly conserved T-loop, indicating activation by upstream kinases via phosphorylation of threonine. Experiments show that phosphorylation of threonine at position 211 of NUAK1 by LKB1 or phosphorylation of serine at position 600 by AKT activates NUAK1 activity. The activated NUAK1 activity is 10-20 times higher than the baseline level (Lizcano et al., 2004). The activity regulation mechanism of NUAK2 is highly similar to that of AMPK. Phosphorylation of threonine at position 208 of the T-loop of NUAK2 by LKB1 is equivalent to phosphorylation at position 172 of AMPK. This activation increases NUAK2 activity by 50-fold, demonstrating the important role of NUAK2 in LKB1 function. In conclusion, NUAK1 and NUAK2 play important roles in normal cellular energy homeostasis and in tumor formation, invasion, and metastasis. NUAK1 and NUAK2 may be potential therapeutic targets for cancer and metabolic diseases.

[0007] Banerjee et al. (Biochemical J. 2014, 457(1), 215) reported highly specific NUAK1 kinase inhibitors WZ4003 and HTH-01-015. Their study found that in drug-resistant cells that highly expressed the NUAK1 [A195T] mutant rather than wild-type NUAK1, WZ4003 or HTH-01-015 inhibited NUAK1 phosphorylation at the Ser445 site of MYPT1. The inhibitory effects of WZ4003 and HTH-01-015 on the migration of MEFs (mouse embryonic fibroblasts) in the wound healing assay were similar to those of NUAK1 knockout. The inhibitory effects of WZ4003 and HTH-01-015 on MEF proliferation were also comparable to those of shRNA knockout of NUAK1. In the 3D U2OS cell invasion assay, the inhibitory effects of WZ4003 and HTH-01-015 on U2OS cell invasion were also comparable to those of NUAK1 knockout. Therefore, WZ4003 and HTH-01-015 can serve as useful tools for studying the biological functions of NUAK kinase.

When cell confluence reached approximately 80%, cells were gently aspirated from the bottom of the culture dish using a 1 mL pipette, and the cell suspension was collected and centrifuged at 500 rpm for 3 min. The supernatant was discarded, and the cells were resuspended in complete culture medium. The cells were then seeded into culture dishes at an appropriate ratio and incubated statically at 37°C in a 5% CO2 incubator. Cells were passaged until they reached good growth and approximately 80% confluence and were then used for experiments. Cells in the logarithmic growth phase were gently aspirated from the well using a 1 mL pipette, centrifuged at 500 rpm for 3 min, and the supernatant was discarded. The cells were resuspended in fresh culture medium, dispersed into single cells, and counted. Cells were seeded at a density of 1000 cells per well into 96-well cell culture plates (the first column was empty) and incubated overnight at 37°C in a 5% CO2 incubator. The following day, the stock solution of the compound was serially diluted with DMSO at a ratio of 1:3 to obtain nine concentrations. 2 μL of each concentration was added to 98 μL of medium (10-fold dilution). A DMSO control well was also prepared. Cells were removed from the CO2 incubator, and the old medium in the wells was discarded. 135 μL of fresh medium was added to each well, followed by 15 μL of the corresponding concentration of the compound diluted in medium. The plate was then incubated at 37°C in a 5% CO2 incubator for 7 days. After 7 days, 100 μL of CellTiter-Glo reagent was added to each well, and the plate was shaken on a track-mounted shaker for 2 minutes to induce complete cell lysis. The plate was then incubated at room temperature for 10 minutes, and the chemiluminescence values ​​were read using a plate reader. The inhibitory activity of the compound on cell proliferation was plotted on a graph as the compound's inhibition rate against cell proliferation and the compound's concentration. Cell inhibition rate (%) = (chemiluminescence value) / (…) 待测药 - Chemiluminescence value DMSO对照孔 ) / (chemiluminescence value) 培养液对照 - Chemiluminescence value DMSO对照孔 )×100%.
