Abstract
Description
[Technical Field]
[0001] The present invention relates to agonists selective for thyroid hormone receptor β. More specifically, the present invention relates to thyroid hormone receptor β subtype agonist compounds represented by general formula (I), pharmaceutical compositions thereof, and their use in the manufacture of medicaments for treating related diseases. [Background technology]
[0002] Thyroid hormones (THs) are produced in the thyroid gland and secreted into the circulation (hypothalamus-pituitary-thyroid axis) as two distinct forms: 3,5,3',5'-tetraiodo-L-thyronine (T4) and 3,5,3'-triiodo-L-thyronine (T3). While T4 is the predominant form secreted by the thyroid gland, T3 is the more physiologically active form. T4 is present in all tissues but is converted to T3 by tissue-specific deiodinases present primarily in the liver and kidney. The biological activity of thyroid hormones is mediated by thyroid hormone receptors (THRs). THRs are encoded by distinct genes, expressing α and β receptors located on chromosomes 17 and 3, respectively. Alternative shearing of the primary transcript generates distinct protein subtypes, THRα1, THRα2, THRβ1, and THRβ2, respectively. THRβ1, THRβ1, and THRβ2 are derived from differential promoter expression, and these two subtypes differ only in their amino termini. THRα1 and THRα2 are derived from differential splicing of precursor mRNA and differ primarily in their carboxyl termini. Of these, THRα1, THRβ1, and THRβ2 can bind thyroid hormone. Thyroid hormone receptor subtypes have been shown to differentially contribute to specific physiological responses. THRβ1 plays an important role in regulating thyroid-stimulating hormone in the liver. THRβ2 plays a major role in regulating thyroid-stimulating hormone. Thyroid hormones play a role in lowering serum low-density lipoprotein (LDL) levels. Hyperthyroidism is associated with decreased serum total cholesterol, which is due to thyroid hormones increasing hepatic LDL receptor expression and promoting cholesterol metabolism into bile acids. Hypothyroidism is associated with hypercholesterolemia, and thyroid hormone replacement therapy is known to lower total cholesterol. Thyroid hormones may also reduce the risk of atherosclerosis and other cardiovascular diseases. The incidence of atherosclerotic vascular disease is directly related to LDL cholesterol levels.Thyroid hormones may reduce body weight, improve obesity-associated comorbidities, and have beneficial effects on glycemic control in obese patients with type 2 diabetes by increasing metabolic rate, oxygen consumption, and heat production.
[0003] The development of thyroid mimetics that maintain the beneficial effects of thyroid hormones while avoiding the side effects of hyperthyroidism and hypothyroidism could open new therapeutic avenues for patients with metabolic disorders such as obesity, hyperlipidemia, hypercholesterolemia, and diabetes, as well as hepatic steatosis, non-alcoholic steatohepatitis, atherosclerosis, cardiovascular disease, hypothyroidism, thyroid cancer, thyroid disorders, and related conditions and diseases.
[0004] MGL-3196 is a first-in-class, orally available, small-molecule, hepatic thyroid hormone receptor β (THR-β) selective agonist. Preclinical toxicology and Phase 1 clinical data suggest that MGL-3196 significantly reduced LDL cholesterol, triglycerides, and lipoproteins for the treatment of nonalcoholic steatohepatitis (NASH) and dyslipidemia (Journal of Hepatology, 2018, vol. 68, s37-s64). This suggests that MGL-3196 may be an ideal candidate for reducing cardiovascular risk in patients with NASH, as well as in patients with dyslipidemia receiving moderate doses of statins or who are intolerant to statins (European Heart Journal, Volume 39, Issue suppl_l, August 2018, ehy566.P5387). Phase 2 clinical data showed that adverse events (AEs) were primarily mild (85%) and moderate (15%), with three cases of serious AEs unrelated to treatment (Journal of Hepatology, 2018, vol. 68, S37_S64). [ka]
[0005] Although MGL-3196 is effective as a THR-β agonist in treating various diseases, it remains difficult to discover new compounds that have the beneficial effects of thyroid hormones while avoiding side effects and that have good oral bioavailability and drug formation properties. Therefore, there remains a need in the art for the development of THR-β selective agonists with better specificity, pharmacodynamics, and pharmacokinetic properties. The present invention provides such compounds. Summary of the Invention

Then, using liposomal Lipofectamine 2000, they were co-transfected with a human THRα eukaryotic expression plasmid or a human THRβ eukaryotic expression plasmid and a reporter plasmid containing a THR response element driven by PGL4.26-DR4-Luc. The procedure was described in the Lipofectamine 2000 instructions. The day after transfection, phenol red-free DMEM medium (containing 5% charcoal-stripped FBS) was seeded into 96-well cell culture plates at a density of 20,000 cells per well in a volume of 135 μL per well. Six hours after seeding, cells were allowed to form a wall. Compounds dissolved in DMSO were diluted 20-fold with phenol red-free DMEM medium (containing 5% charcoal-stripped FBS) to a final concentration of 10x and added to cell wells at 15 μL / well; the compounds were again diluted 10-fold to the final concentration. Triiodothyronine T3 (100 nM) was used as a positive control, and 0.5% DMSO was used as a blank control. After administration, cells were incubated overnight (16 hours) at 37°C in a 5% CO2 incubator. After incubation, the medium was discarded, and 35 μL of serum-free phenol red-free DMEM medium was added to each well. 35 μL of Steady-Glo was added, and the samples were shaken at room temperature for 10 minutes in the dark, after which the chemiluminescence values of the samples were measured.
[0386] The agonist activity of the compound was calculated as follows: % Effect = (compound - blank control) / (positive control - blank control) x 100%. EC of the compound 50 was calculated by fitting the logarithm of the agonist activity of the compound to the compound concentration using GraphPad Prism. A lower EC50 value indicates better activity.
[0387] EC of agonist activity of compounds for THRα and THRβ 50The values were first corrected by the EC50 values of the agonist activity of T3 on THRα and THRβ in the same experiment, respectively, and the resulting values were used to calculate the fold selectivity, i.e., receptor selectivity. Specifically, it was calculated as follows: Selectivity = (Compound THRα EC 50 / T3 THRα EC 50 ) / (compound THRβ EC 50 / T3 THRβ EC 50 ) The higher the value, the more selective the compound is for the THRβ receptor.
[0388] Resmetirom (MG1-3196), a highly selective THR-β agonist, was used as a positive control (Reference: J Med Chem. 2014, 57(10):3912-3923). [Table 1] JPEG0007729891000122.jpg213159
[0389] The experimental results showed that the activity or selectivity of some compounds having the structures of the present disclosure (e.g., ZB-H-02, ZB-H-17, ZB-H-18, ZB-H-25, ZB-H-26, ZB-H-33, ZB-H-38, ZB-H-74, ZB-H-75, ZB-H-76, ZB-H-81, ZB-H-95, etc.) was significantly higher than that of the positive compound, and the activity or selectivity of most of the other compounds was comparable to that of the positive compound (MG1-3196).
[0390] Example 97: Effect of reducing serum cholesterol levels measured in ICR mice after a single administration of the compound
[0391] ICR mice were used as test animals, and changes in serum cholesterol levels were measured after intragastric administration of a compound. ICR mice (male, 7-8 weeks old) were randomly divided into groups according to body weight. The vehicle control group received intragastric administration of 0.25% CMC-Na, while the compound group received a single dose of the corresponding compound to be tested. On the day of administration, the mice were fasted overnight. 24 hours after administration, blood was collected and serum was obtained. Cholesterol levels in the serum of the mice were measured using a Total Cholesterol Assay Kit (Zhejiang Dong'ou Diagnostic Products Co., Ltd.). The percentage reduction in serum cholesterol levels in each group of mice was calculated, with the vehicle control group set at 100%. [Table 2] JPEG0007729891000124.jpg75159
[0392] Experimental results 24 hours after administration confirmed that the compound had a certain effect in the animal body.
