Description

Thyroxine beta receptor selective agonist compounds, pharmaceutical compositions thereof and uses TECHNICAL FIELD

[0001] The present invention relates to thyroxine beta receptor selective agonists. More particularly, the present invention relates to a thyroxine beta subtype receptor agonist compound according to general formula (I), pharmaceutical compositions thereof, and uses thereof in the manufacture of a medicament for the treatment of related diseases. BACKGROUND

[0002] Thyroid hormone (TH) is produced by the thyroid gland and secreted into the circulation (hypothalamic / pituitary / thyroid system) in two forms, 3,5,3',5'-tetraiodo-L-thyronine (T4) and 3,5,3'-triiodo-L-thyronine (T3), which play a pivotal role in maintaining human metabolism and cardiovascular function, etc. T4 is the major form secreted by the thyroid gland and T3 is the more physiologically active form. T4 is converted to T3 by tissue-specific deiodinases, which are present in all tissues, but predominantly in the liver and kidney. The biological activity of thyroid hormone is mediated by thyroid hormone receptors (THR). THRs are encoded by different genes expressed on human chromosomes 17 and 3 for α and β, respectively, and produce different protein isoforms by alternative splicing of the primary transcript, two isoforms for each gene, i.e. THR-αl, THR-α2, THR-βl and THR-β2. THR-βl and THR-β2 are expressed from the promoter differences, and the two isoforms differ only in the amino-terminal end. THR-αl and THR-α2 are produced by differential splicing of the pre-mRNA, and differ mainly in the carboxy-terminal end. Among them, THR-αl, THR-βl and THR-β2 can bind thyroid hormone. Current studies have confirmed that the physiological effects of different thyroid hormone receptor isoforms activated by thyroid hormone are not the same. THR-αl is mainly responsible for maintaining cardiovascular function; THR-βl plays an important role in regulating thyroid-stimulating hormone and regulating thyroid hormone; and THR-β2 plays a major role in regulating thyroid-stimulating hormone. Thyroid hormone has the effect of reducing serum low density lipoprotein (LDL). Hyperthyroidism is associated with low total serum cholesterol, which is attributed to thyroid hormone increasing the expression of LDL receptors in the liver and stimulating the metabolism of cholesterol to bile acid. Hypothyroidism is associated with hypercholesterolemia, and thyroid hormone replacement therapy is known to reduce total cholesterol. Thyroid hormone can also reduce the risk of atherosclerosis and other cardiovascular diseases. The incidence of atherosclerotic vascular disease is directly related to the level of LDL cholesterol. Thyroid hormone has beneficial effects on obese patients by increasing metabolic rate, oxygen consumption and heat release, thereby reducing body weight, improving obesity-related comorbidities, and can also have beneficial effects on blood glucose control in obese patients with type II diabetes.

[0003] Thyroid analogs that avoid the adverse effects of hyperthyroidism and hypothyroidism while retaining the beneficial effects of thyroid hormones would be a new approach to treat patients with metabolic diseases, such as obesity, hyperlipidemia, hypercholesterolemia, diabetes, and other conditions, such as metabolic dysfunction associated steatohepatitis (MASH), atherosclerosis, cardiovascular disease, hypothyroidism, thyroid cancer, thyroid disease, and related conditions and diseases.

[0004] MGL-3196 is the first THR-β agonist approved by FDA on March 14, 2024 for treating MASH, ending the 40-year plight of MASH without available drugs. The results of its clinical phase II experiment show that the health-related quality of life (HRQL) of MASH and liver fibrosis patients is significantly improved, and the NAS score is significantly reduced (NCT02912260). The results of the clinical phase III experiment show that the proportion of MASH regression and no fibrosis deterioration in the 80 mg dose experiment group and the 100 mg dose experiment group taking MGL-3196 for 52 weeks is 25.9% and 29.9%, which is significantly higher than that of the control group (9.7) (NCT03900429). Safety tests show that the side effects of MGL-3196 are only common in the early stage of taking the drug, and most of them are mild adverse reactions such as nausea and diarrhea, showing good safety and tolerability of MGL-3196 (NCT04197479).

[0005] Although MGL-3196 is the first and currently the only THR-β agonist for treating MASH on the market, its therapeutic effect is still not as expected. It is still a challenging task to develop new compounds that maximize the therapeutic effect of thyromimetic therapy, avoid side effects, and have good oral bioavailability and drug properties. Therefore, there is still a need to develop THR-β selective agonists with better specificity / pharmacodynamics / pharmacokinetics in the art, and the present application provides such compounds.

[0342] Example 41: Detection of agonistic activity of compounds on THRα and THRβ by THR reporter gene method

[0343] Huh7 cells were cultured in DMEM medium containing 10% FBS. Cells were seeded into 10cm cell culture dishes and allowed to proliferate to approximately 90% confluence. They were then co-transfected with human THRα eukaryotic expression plasmid or human THRβ eukaryotic expression plasmid and the reporter gene plasmid PGL4.26-DR4-Luc containing a THR response sequence driven by liposome Lipofectamine 2000. The procedure was performed according to the Lipofectamine 2000 manufacturer's instructions. The day after transfection, cells were seeded into 96-well cell culture plates with phenol red-free DMEM medium (containing 5% carbon-adsorbed fetal bovine serum) at a density of 20,000 cells per well and a volume of 135 μL per well. Six hours after seeding, cells adhered. A compound dissolved in dimethyl sulfoxide was diluted 20-fold to 10-fold with phenol red-free DMEM medium (containing 5% carbon-adsorbed fetal bovine serum) and added to each well at a final concentration of 15 μL, thus achieving a final concentration by further dilution 10-fold. The positive control was set as triiodothyronine T3 (100 nM), and the blank control was 0.5% dimethyl sulfoxide. After drug administration, the cells were cultured overnight (16 h) at 37°C in a 5% CO2 incubator. After incubation, the culture medium was discarded, and 35 μL of serum-free and phenol red-free DMEM culture medium and 35 μL of Steady-Glo were added to each well. After shaking at room temperature in the dark for 10 min, the chemiluminescence value of the samples was detected.

[0344] The agonistic activity of a compound is calculated as follows: Effect % = (Compound - Blank Control) / (Positive Control - Blank Control) × 100%. The EC50 of the compound... 50 EC was obtained by fitting the agonistic activity of the compound to the logarithm of the compound concentration using GraphPad Prism. 50 The lower the value, the better the activity.

[0345] EC50 of the compound’s agonistic activity against THRα and THRβ 50 The values ​​were first calculated using the EC50 values ​​of T3 on the agonistic activity of THRα and THRβ in the same experiment. 50 After value correction, the fold increase, i.e., receptor selectivity, is calculated based on the obtained value. The specific calculation method is as follows: Selectivity = (compound THRαEC) / (receptor selectivity) * (receptor selectivity ... 50 / T3 THRαEC 50 ) / (compound THRβEC 50 / T3 THRβEC 50 The higher the value, the higher the selectivity of the compound for the THRβ receptor.

[0346] The positive control drugs are Resmetirom (MGL-3196), ZB-H-74 and ZB-H-76. They are reported as highly active and selective THR-β agonists. (Reference: J Med Chem. 2014, 57(10): 3912-3923; CN114634486B).

[0347] The experimental results show that the activity or selectivity of some of the test compounds of the structure of the present disclosure is significantly higher than that of the three positive compounds, and the activity or selectivity of most of the other compounds is comparable.

[0348] Example 42: The reducing effect of a single dose of the compound on the serum total cholesterol and low-density lipoprotein cholesterol levels of mice after 24 hours

[0349] ICR mice were used as test animals to test the changes in serum total cholesterol and low-density lipoprotein cholesterol levels after oral administration of the compound to mice. ICR mice (male, 7-8 weeks old) were randomly divided according to body weight. The solvent control group was given 0.25% CMC-Na by gavage, and the compound group was given the corresponding test compound by gavage, respectively, for a single dose. On the day of administration, the mice were fasted overnight, and 24 hours after administration, blood was collected and serum was collected. The automatic biochemical analyzer was used to determine the serum total cholesterol and low-density lipoprotein cholesterol levels of mice. The percentage reduction in serum total cholesterol and low-density lipoprotein cholesterol levels of mice in each group was calculated based on the solvent control group as 100%.

[0350] The experimental results after 24 hours of administration show that the test compound has better single animal in vivo efficacy compared with the positive compound MGL-3196.

[0351] Example 43: Pharmacodynamic evaluation of the compound on a mouse model of non-alcoholic steatohepatitis induced by high-fat diet combined with carbon tetrachloride

[0352] The experiment selected male C57 mice, 5-6 weeks old, were given high-fat diet and control feed respectively, and were induced for 14 weeks. Then, the mice were injected with CCl4 (0.05 μl / g) intraperitoneally, twice a week, and the carbon tetrachloride injection was performed for 6 weeks as the endpoint of the experiment. At the same week when the CCl4 injection was started, the mice were given ZB-B-13 (3 mg / kg), ZB-A-10 (1 mg / kg) and MGL-3196 (3 mg / kg) by gavage, once a day, and the administration was continuously performed until the end of the experiment. After the end of the experiment, the blood samples of the mice were collected, and the serum was separated for detecting the biochemical indexes such as serum alanine aminotransferase (ALT), serum total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C); the liver was separated, fixed and embedded, and the section was cut, stained with hematoxylin-eosin (H&E) and scored for pathology; the Sirius red staining was used to evaluate the liver fibrosis level, and the therapeutic effect of the compounds on non-alcoholic steatohepatitis was comprehensively evaluated.

[0353] The experimental results are shown in FIGS. 1-5. Compared with the model control group, after 6 weeks of oral administration, ZB-B-13 (3 mg / kg), ZB-A-10 (1 mg / kg) and MGL-3196 (3 mg / kg) significantly reduced the serum ALT, total cholesterol and LDL-C levels of the mice, and ZB-A-10 (1 mg / kg) was more effective than MGL-3196 (3 mg / kg); the results of HE staining of liver sections showed that, compared with the model control group, ZB-B-13 (3 mg / kg), ZB-A-10 (1 mg / kg) and MGL-3196 (3 mg / kg) significantly improved the liver steatosis, hepatocyte ballooning and lobular inflammation of the mice, and significantly reduced the NAS score, and ZB-B-13 (3 mg / kg) and ZB-A-10 (1 mg / kg) were more effective than MGL-3196 (3 mg / kg); the results of Sirius red staining of liver tissue sections showed that, after treatment with ZB-B-13 (3 mg / kg), ZB-A-10 (1 mg / kg) and MGL-3196 (3 mg / kg), the liver fibrosis level of the NASH mice was significantly reduced, and ZB-B-13 (3 mg / kg) and ZB-A-10 (1 mg / kg) were more effective than MGL-3196 (3 mg / kg). The above results suggest that ZB-B-13 and ZB-A-10 have a significant therapeutic effect on non-alcoholic steatohepatitis mice induced by high-fat diet combined with carbon tetrachloride after long-term administration, and the drug efficacy is higher than that of MGL-3196.

[0354] Example 44: Reducing effect of a single administration of compound ZB-A-10 on serum total cholesterol and low density lipoprotein cholesterol levels of mice for 72 hours

[0355] The ICR mice were used as the test animals to test the changes of serum total cholesterol and low density lipoprotein cholesterol levels of the mice after a single gavage administration of compound ZB-A-1072 for 72 hours. The ICR mice (male, 7-8 weeks old) were randomly divided according to the body weight. The solvent control group was gavaged with 0.25% CMC-Na, and the compound group was respectively given the corresponding test compound, single administration. On the 3rd day of administration, the mice were fasted overnight, and 72 hours after administration, blood was collected and serum was collected. The automatic biochemical analyzer was used to determine the serum total cholesterol and low density lipoprotein cholesterol levels of the mice. The percentage reduction of serum total cholesterol and low density lipoprotein cholesterol levels of each group of mice was calculated based on the solvent control group as 100%.

[0356] The results showed (Figure 6) that after a single gavage administration of 3 mg / kg MGL-3196 to mice, the serum total cholesterol and low density lipoprotein cholesterol did not significantly decrease after 72 hours. However, after a single gavage administration of 1 mg / kg or 3 mg / kg ZB-A-10 to mice, the serum total cholesterol significantly decreased by 40.4% and 45.1%, and the serum low density lipoprotein cholesterol also significantly decreased by 54.3% and 55.0%, indicating that ZB-A-10 has long-term application potential for reducing serum total cholesterol and low density lipoprotein cholesterol.

[0357] Example 45: Pharmacodynamic evaluation of compound ZB-A-10 (once every 3 days orally administered) on a mouse model of non-alcoholic steatohepatitis induced by high-fat diet combined with carbon tetrachloride (HFD+CCl4)

[0358] In this experiment, male C57 mice, 5-6 weeks old, were given high-fat diet and control feed respectively, and after 14 weeks of induction, CCl4 (0.05 μl / g) was injected intraperitoneally, twice a week, and carbon tetrachloride injection was performed for 6 weeks as the endpoint of the experiment; at the same week when CCl4 injection began, ZB-A-10 (1 mg / kg, once every 3 days) and MGL-3196 (3 mg / kg, once a day) were administered by gavage, and the administration was continued until the end of the experiment. After the end of the experiment, the blood samples of the mice were collected, and the serum was separated for the detection of biochemical indicators such as serum alanine aminotransferase (ALT), serum total cholesterol (TC), and low density lipoprotein cholesterol (LDL-C); the liver was separated, fixed and embedded, and the main lobe was sectioned, stained with hematoxylin-eosin (H&E) and scored pathologically; Sirius red staining was used to evaluate the level of liver fibrosis, and the therapeutic effect of the compound on non-alcoholic steatohepatitis was comprehensively evaluated.

[0359] The experimental results are shown in Figures 7-11. Compared with the model control group (HFD+CCl4), both ZB-A-10 (1 mg / kg, once every 3 days) and MGL-3196 (3 mg / kg, once a day) significantly reduced the serum ALT, total cholesterol and LDL-C levels of mice after 6 weeks of oral administration; the results of liver section HE staining showed that, compared with the model control group, both ZB-A-10 (1 mg / kg, once every 3 days) and MGL-3196 (3 mg / kg, once a day) significantly improved the liver steatosis, hepatocyte ballooning and lobular inflammation of mice, and significantly reduced the NAS score, and the effect of ZB-A-10 (1 mg / kg, once every 3 days) was stronger than that of MGL-3196 (3 mg / kg, once a day); the results of Sirius red staining of liver tissue sections showed that, after treatment of ZB-A-10 (1 mg / kg, once every 3 days) and MGL-3196 (3 mg / kg, once a day), the liver fibrosis level of NASH mice was significantly reduced, and the effect of ZB-A-10 (1 mg / kg, once every 3 days) was stronger than that of MGL-3196 (3 mg / kg, once a day). The above results suggest that long-term administration of ZB-A-10 (once every 3 days orally) has a significant therapeutic effect on non-alcoholic steatohepatitis mice induced by high-fat diet combined with carbon tetrachloride, suggesting that it has significant long-term application potential, and the drug efficacy is better than that of MGL-3196.
