Abstract
Description
Technical Field
[0001] This invention relates to a benzothiazole compound and a benzimidazole compound, or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition for the prevention or treatment of diseases related to the silent information regulator 7 (SIRTUIN 7) protein (hereinafter referred to as "SIRT7") containing the latter as an active ingredient. Background Technology
[0002] It has been reported that seven silencing information regulator (SIRTUIN) proteins, from SIRT1 to SIRT7 (hereinafter referred to as "SIRT"), have been identified to date, and SIRTs are involved in aging, metabolic diseases, and gene stability. Furthermore, SIRT7 has been reported to be present in the nucleolus and nucleoplasm (Kiran et al., FEBS J, 2013), playing an important role in cellular stress.
[0003] As an example, it has been reported that when SIRT7 is overexpressed, the expression of HIF-1α decreases independently of catalytic activity, while the expression of HIF-1α increases when treated with siRNA (Hubbi et al., J Biol Chem, 2013), thus SIRT7 intervenes in hypoxia.
[0004] Furthermore, SIRT7 is associated with hypoglycemic stress. For example, under hypoglycemic conditions or during AICAR treatment, which is an agonist of adenosine monophosphate kinase (AMPK), SIRT7 translocates from the nucleolus to the nucleoplasm. This can be seen as inhibiting rDNA transcription by reducing the binding between the nucleolus and PAF53, which can be explained as a system that responds to energy depletion (Chen et al., MolCell, 2013).
[0005] Furthermore, when the endoplasmic reticulum is stressed, SIRT7 messenger ribonucleic acid (mRNA) increases. This is because the activity of Myc is inhibited before the promoters of genes such as ribosomal protein (RPS20), which are endoplasmic reticulum stress response proteins, thus reducing the transcription of these genes. Therefore, it has been reported to inhibit endoplasmic reticulum stress (Shin et al., Cell Rep, 2013).
[0006] As another example, SIRT7 intervention in aging has been reported, including shortened lifespan (Vakhrusheva et al., Circ Res, 2008) and age-related hearing loss (Ryu et al., Cell Metabolism, 2014) in SIRT7 knockout mice, and reduced SIRT7 expression observed in aging mouse models (Lee et al., Proteomics, 2014) and in hepatocytes of aging mouse models (Ghiraldini et al., Mol Biol Cell, 2013). This suggests that SIRT7-based deacetylation of NPM1 helps inhibit aging (Lee et al., Proteomics, 2014).
[0007] Furthermore, SIRT7 interferes with DNA damage responses. For example, SIRT7 knockout mouse embryonic fibroblast (MEF) cells with higher ac-p53 knockout levels are more sensitive to adriamycin- or hydrogen peroxide-induced apoptosis (Vakhrusheva et al., J Physiol Pharmacol, 2008; Vakhrusheva et al., Cir Res, 2008). It was also observed that paraquat treatment increased homologous recombination efficiency when SIRT7 was overexpressed (Mao et al., Science, 2011). Moreover, it was found that doxorubicin-induced apoptosis or cellular senescence was reduced by inhibiting p38 and JNK activity when SIRT7 was overexpressed (Kiran et al., Exp Cell Res, 2014).
[0008] Furthermore, the association between SIRT7 and cancer has been reported. For example, SIRT7 has been reported to suppress the expression of tumor suppressor genes by mediating the deacetylation of H3K18 (Barber et al., Nature, 2012). Increased expression of SIRT7, regulated by mir-125a-5p and mir-125b, has led to increased growth of liver cancer cells (Kim et al., Hepatology, 2013). Moreover, increased SIRT7 expression has been observed in thyroid and breast cancer (de Nigris et al., Br J Cancer, 2002; Frye, Br J Cancer, 2002; Ashrafet et al., Br J Cancer, 2006).
[0009] Therefore, it is expected that compounds that inhibit SIRT7 activity or their pharmaceutically acceptable salts may be used for the treatment or prevention of SIRT7-related diseases. Summary of the Invention

[0576] Experimental Example 1: Measurement of Sirt7 Inhibitory Activity
[0577] The SIRT7 protein was prepared using the Promega Cat. No. 6450 SIRT Glo assay kit and the SignalChem Cat. No. S41-30H protein as the target. The compound was prepared by diluting it twice its final concentration in SIRT Glo buffer. In the positive control and compound groups of white 384-well plates (Greiner Bioone, white, small volume, Cat. No. 874075), 5 μL of SIRT7 protein was diluted in SIRT Glo buffer and dispensed as 20 ng per well. In the background control, 10 μL of SIRT Glo buffer was dispensed.
[0578] Add 5 μL of SIRT Glo buffer to the positive control group and 5 μL of diluted compound to the compound group, and react for 30 minutes. Prepare the substrate provided in the SIRT Glo assay by adding 10 μL each time. After reacting for 1 hour, measure luciferase activity using a microplate reader (Molecular Device, Spectramax i3).
[0579] The luciferase values of the background control group were removed from all wells. The sirt7 activity inhibition rate of the compound was calculated using the following formula: Inhibition rate (% inhibition) = 100 - (compound group / positive control group) × 100. The results are shown in Table 1 below.

[0585] Experimental Example 2: The inhibitory effect of Sirt7 inhibitor compounds on cancer cell proliferation
[0586] KRAS, as part of the RAS / MAPK pathway, promotes carcinogenesis by boosting cell growth and proliferation. Mutations in KRAS are found in approximately 20% of solid tumors, primarily pancreatic, colon, and lung cancers. Sirt7 has been reported to increase MAPK activity through upregulation of p-ERK and p-MEK, thereby increasing the incidence of colon cancer. Therefore, in this study, the cancer cell proliferation inhibitory activity of the compounds of this invention was evaluated using COLO320DM (KRAS wild-type) and SW480 (KRAS mutant) cells, which are human colon cancer cells.
[0587] For cell proliferation, cytotoxicity was determined using CCK-8 (Cell counting kit: Dojindo, Cat. No. CK04). Absorbance at 450 nm was measured based on the presence or absence of orange light, indicating the activity of dehydrogenases in live cells. COLO320DM and SW480 cells were seeded at 3,000 cells per well in 96-well plates (BD Falcon, Cat. No. 353072). After 24 hours, each screened inhibitor was applied, with treatment occurring at 2-day intervals during medium replacement, for a total of 4 days. For cell proliferation, 10 μL of CCK-8 was added to each well, and after incubation at 37°C for 30 minutes, absorbance was measured at 450 nm using a microplate reader (Molecular Device, Spectramax i3).
[0588] As a comparative compound, a Sirt7 inhibitor reported in Biochem Biophys Res Commun. 2019; 508: 451-457 was synthesized and used. Hereinafter, 97491 denotes the above comparative compound.

[0592] Experiment Example 3: Lactate dehydrogenase (LDH) cytotoxicity experiment
[0593] Lactate dehydrogenase (LDH), an enzyme present in the cytoplasm, normally does not cross the cell membrane, but if the cell membrane is damaged, it is released into the extracellular space (i.e., into the culture medium). The released LDH is measured to determine the toxicity of the compounds. Compound 97491 and compounds 1-37 of this invention were compared by treating COLO320DM and SW480 cells at high concentrations of 100 μM and 500 μM.
[0594] The Thermo Fisher Scientific Cat. No. 88953LDH Cytotoxicity Assay Kit was used. 20,000 cells were seeded in 96-well plates and cultured for 24 hours, followed by treatment with 100 μM and 500 μM compounds. Forty-eight hours later, 50 μL of the compound-treated culture supernatant was transferred to a new 96-well plate, and 50 μL of the substrate mix buffer provided in the kit was added. The mixture was incubated at room temperature for 30 minutes in the dark. Then, 50 μL of stop solution was added, and the absorbance was measured at 490 nm using a microplate reader (Molecular Device, Spectramaxi3).
[0595] The result, refer to Figure 2(a) Confirmed that in COLO320DM cells, the cytotoxicity compared to the positive control group that caused complete cell membrane damage was as follows: 51.9% for 100 μM comparative compound 97491, 59.2% for 500 μM comparative compound 97491, 62.1% for 100 μM compound 1-37 of the present invention, and 62.0% for 500 μM compound 1-37 of the present invention. In SW480 cells, the cytotoxicity compared to the positive control group that caused complete cell membrane damage was as follows: 13.4% for 100 μM comparative compound 97491, 46.7% for 500 μM comparative compound 97491, 14.8% for 100 μM compound 1-37 of the present invention, and 45.1% for 500 μM compound 1-37 of the present invention.

[0597] Experimental Example 4: In vivo activity evaluation
[0598] The compounds of this invention were administered to xenograft tumor-bearing mice, and their in vivo tumor-suppressive activity was measured. Five-week-old BALB / c nu-female laboratory mice were introduced. COLO320DM and SW480 cells, which are human colorectal cancer cells, were isolated from culture flasks using trypsin and administered at 1×10⁻⁶. 8 Cells / ml concentrations were prepared. Mixed 100 μL with basement membrane matrix (Matrigel) (Gibco, Cat. No. A14133-02) at a 1:1 ratio, the mixture was subcutaneously injected into the dorsal side of 5-week-old mice. Two weeks later, when the tumor volume in the mice reached 100 mmHg... 3 At that time, the compound was administered orally 5 times a week. (Day 0) This was followed for 3 weeks.
[0599] The compound was dissolved in 0.1% carboxymethyl cellulose (CMC) and 0.2% Tween 80 solutions at concentrations of 2 mg / ml, 4 mg / ml, and 8 mg / ml, and administered orally at 100 μL to achieve concentrations of 10 MPa, 20 MPa, and 40 MPa, respectively. For the negative control group, the same route of administration and frequency of administration were used instead of the compound, with the same 0.1% carboxymethyl cellulose and 0.2% Tween 80 solutions administered. Six mice were used in each experimental group. Figure 3 The tumor size was measured every three days by measuring its major axis (length, L) and minor axis (width, W), and the tumor volume (mm²) was calculated as (L×W×W) / 2. 3 This allowed for the calculation of the mean for each group. Statistical processing was performed using the Graph Pad Prism6 program, with p-values less than 0.05 considered significant.
[0600] Five-week-old nude mice with suppressed immune systems due to T-cell reduction caused by thymus ablation were introduced and subcutaneously injected with COLO320DM and SW480, human colorectal cancer cell lines. Results of oral administration for 3 weeks of the present invention compounds 1-37 (10 mpk, 20 mpk, 40 mpk), 1-105 (100 mpk), and 1-106 (100 mpk), as Sirt7 inhibitors, were compared with those of the present invention. Figure 4 As shown in Figure 11, compared to the control group that was only fed a solution containing the reagent, the tumor size of both cell lines was reduced, and the results of the first and second in vivo experiments were consistent. In the group of mice injected with COLO320DM, the most significant tumor generation inhibition effect was observed when the compound of the present invention was administered orally at 40 mpk, and this inhibition effect was concentration-dependent.
