Description

[Technical Field]

[0001] <Cross-reference of related applications> This disclosure claims priority and interest to the Chinese patent application No. 202210999229.5 filed with the China National Intellectual Property Administration on 19 August 2022, and the disclosures of the said application are incorporated herein by reference in their entirety.

[0002] <Technical field> The present invention belongs to the field of medicinal chemistry and relates to a polycyclic compound that is a thyroid hormone β receptor agonist, a pharmaceutical composition containing the same, a method for producing the same, and its use in producing pharmaceuticals for the prevention, treatment, or relief of diseases regulated by thyroid hormone β receptors. [Background technology]

[0003] Thyroid hormones (TH) are synthesized in the thyroid gland in response to thyroid-stimulating hormone (TSH) secreted by the pituitary gland. Thyroid hormones play a crucial role in regulating bodily growth, development, metabolism, and homeostasis. Thyroid hormones function by binding to thyroid hormone receptors (THRs). THRs belong to a superfamily of nuclear receptors, and these nuclear receptors, together with their common ligand, the retinoid X receptor, form heterodimers and function as ligand-inducible transcription factors. Like other nuclear receptors, THRs possess ligand-binding domains and DNA-binding domains, and regulate gene expression through ligand-dependent interactions with DNA effector elements (thyroid effector elements, THREs).

[0004] Currently, there are two subtypes of THR: THRα and THRβ. THRα is mainly found in cardiac tissue and plays an important role in regulating cardiac function, while THRβ is mainly expressed in the liver and pituitary gland, regulating fatty acid and cholesterol metabolism and the secretion of thyroid-stimulating hormone. Both THRα and THRβ are expressed in brown adipose tissue (BAT) and play important roles in regulating basal oxygen consumption, fat accumulation, lipogenesis, and lipolysis (Oppenheimer et al., J.Clin.Invest.87(1):125-32(1991)).

[0005] THR agonists can increase metabolic rate, oxygen consumption, and heat production, promote the metabolism of cholesterol to bile acids, and even lower lipoprotein levels associated with atherosclerosis. The liver and heart are the primary target organs of THR agonists. In the liver, they affect carbohydrates by regulating genes mainly related to the synthesis and metabolism of fatty acids and cholesterol, increasing glycogenolysis and gluconeogenesis, and reducing the action of insulin. In the heart, they reduce systemic vascular resistance, increase blood volume, and produce inotropic and chronotropic effects.

[0006] THRβ agonists also promote cellular lipid metabolism and exert functions that lower cholesterol and blood lipids. Therefore, research and development of THRβ agonists is of great significance for the treatment and / or prevention of diseases regulated by thyroid hormone receptors. [Overview of the project] [Means for solving the problem]

[0068] The term "pharmaceutically acceptable ester" refers to an ester that is substantially non-toxic to living organisms and is hydrolyzed in living organisms to form the compound of the present invention or a salt thereof. Pharmaceutically acceptable esters generally include, but are not limited to, esters formed by the compound of the present invention with a pharmaceutically acceptable carboxylic acid or sulfonic acid. Such esters are also called carboxylic acid esters or sulfonic acid esters. The term "isomer" refers to a compound that has the same number and type of atoms, and therefore the same molecular weight, but differs in the spatial arrangement or composition of its atoms. The term "stereoisomer" (or "optical isomer") refers to a stable isomer that has at least one chiral element (including chiral centers, chiral axes, chiral planes, etc.) and therefore has a perpendicularly asymmetric plane, allowing it to rotate plane-polarized light. Since the compounds of the present invention have chiral centers and other chemical structures that can cause stereoisomerism, the present invention also includes these stereoisomers and mixtures thereof. Unless otherwise specified, all forms of stereoisomers of the compounds of the present invention are within the scope of the present invention.

[0069] The term "tautomer" (or "tautomer form") refers to structural isomers with different energies that can be interconverted over a low energy barrier. When tautomerism is possible (for example, in solution), chemical equilibrium of tautomers can be achieved. For example, proton tautomers (or proton transfer tautomers) include, but are not limited to, interconversions by proton transfer such as keto-enol isomerization, imine-enolamine isomerization, and amide-iminol isomerization. Unless otherwise specified, all tautomer forms of the compounds of the present invention are within the scope of the present invention. The term "solvate" refers to a substance formed by a non-covalent intermolecular force between the compound of the present invention (or a pharmaceutically acceptable salt thereof) and at least one solvent molecule. For example, solvates include, but are not limited to, hydrates (including hemihydrates, monohydrates, dihydrates, trihydrates, etc.), ethanol compounds, and acetone compounds.

[0070] The term "N-oxide" refers to a compound formed by the oxidation of a nitrogen atom in the structure of a tertiary amine or nitrogen-containing (aromatic) heterocyclic compound. For example, the nitrogen atom in the core of the compound of formula I can form the corresponding N-oxide.

The present invention encompasses all possible metabolite forms of the compounds of the present invention, i.e., substances formed in the body of an individual administered with the compounds of the present invention. The metabolites of the compounds can be identified by the art known in the art, and their activity can be characterized experimentally.

[0073] The term “prodrug” refers to a derivative compound that, when administered to an organism, can directly or indirectly provide the compound of the present invention. Particularly preferred derivative compounds or prodrugs are those that, when administered to an organism, can enhance the bioavailability of the compound of the present invention (e.g., more readily absorbed into the bloodstream) or facilitate the delivery of the parent compound to the site of action (e.g., the lymphatic system). Unless otherwise specified, all prodrug forms of the compounds of the present invention are within the scope of the present invention, and various prodrug forms are known in the art; see, for example, T. Higuchi, V. Stella, Pro-drugs as Novel Drug Delivery Systems [J], American Chemical Society, Vol. 14, 1975. Furthermore, the present invention further encompasses compounds of the present invention containing protecting groups. In any process for producing the compounds of the present invention, it may be necessary and / or desirable to protect a sensitive or reactive group on any relevant molecule. This forms a chemically protected form of the compound of the present invention. This can be achieved by conventional protecting groups, such as those described, for example, TW Greene, PGM Wuts, Protective Groups in Organic Synthesis [M], John Wiley & Sons, 2006. These protecting groups can be removed at an appropriate subsequent stage using methods known in the industry.

[0074] The term "independently" means that at least two groups (or ring systems) present in a structure having the same or similar numerical ranges may have the same or different meanings under certain circumstances. For example, if substituents X and Y are independently hydrogen, halogen, hydroxyl, cyano, alkyl, or aryl, then when substituent X is hydrogen, substituent Y may be hydrogen, halogen, hydroxyl, cyano, alkyl, or aryl.

[0217] Experimental Example 2: Detection of compound agonist activity against THR α / β by time-resolved fluorescence resonance energy transfer (THR-FRET) 1. Construction of a THR α / β overexpression vector We searched NCBI to find the THRα / β LBD domain sequence, and then constructed pET21-His-GST-dLBT-THRα LBD and pET21-His-GST-dLBT-THRβ LBD overexpression vectors using a fusion method. The accuracy of the sequences was then confirmed by sequencing.

[0218] 2. Recombinant protein expression in E. coli prokaryotic cells Correctly sequenced THRα LBD and THRβ LBD overexpression vectors were transferred to E. coli cells BL21 (DE3), coated onto ampicillin-resistant agar plates, and single clones were selected and amplified in LB medium. These were then transferred to 1 L LB at a ratio of 1:100 for large-scale culture. When the OD value reached 0.8–1.2, 0.5 mM isopropyl-β-D(-)-thiogalactopyranoside (IPTG) was added, and induction was carried out overnight at 18°C. The cells were harvested, fragmented, and purified using a GST column and molecular sieves to obtain two proteins: His-GST-dLBT-THRα LBD and His-GST-dLBT-THRβ LBD. The protein concentrations measured using the Biotechnology Bradford Protein Quantification Kit were 24 μM and 23 μM, respectively.

[0219] 3. Preparation of compounds and preparation of the reaction system The protein was removed from a -80°C refrigerator, and the protein containing the GST-tagged THR α / β LBD domain and the Eu-tagged GST antibody were slowly thawed on ice to prepare a detection buffer containing dithiothreitol (DTT) at a final concentration of 5 mM.

[0220] 3.1 Preparation of the compound The initial concentration of the compound was 100 μM (in DMSO). The compound (100 μM in DMSO) was diluted with DMSO at the same 3-fold gradient to obtain a total of 11 concentrations at the same gradient. Then, the compounds at the concentrations at the same gradient were diluted again 50-fold with a detection solution containing 5 mM DTT.

[0221] 3.2 Preparation of the THR-FRET reaction system The final concentrations of all components were calculated based on a system with a final volume of 20 μL per well. To 18 μL of detection buffer containing 5 mM DTT, GST-tagged THRα / β protein, SRC2 (LKEKHKILHRLLQDSSSPV) polypeptide, XL665 (Cisobio, #610SAXLB), and Eu-labeled GST antibody were added to final concentrations of 2 nM, 200 nM, 0.05 nM, and 7.6 nM, respectively, and 18 μL of protein, polypeptide, and antibody reaction mixtures were prepared per well. 18 μL of the reaction mixture and 2 μL of the diluted compound were added to an Optiplate-384 well plate and reacted at room temperature for 24 hours.

[0222] 3.3 Plate Reading Plate readings were performed using an MD i3X multifunction plate reader at excitation and emission wavelengths of 340 nm and 665 nm, respectively. Using the 616 nm light intensity generated by europium excitation with 340 nm light using the MD i3X multifunction plate reader as background, the intensity of the 665 nm emission generated by XL665 excited by the 616 nm excitation light differed depending on the different activation levels of THRα and THRβ by different compounds. The intensity ratio of these two wavelengths (665 nm and 616 nm) was used as the activation activity of the compound against THRα or THRβ, and normalization was performed using the ratio of the solvent DMSO group. The dose-response curve was fitted with four parameters using GraphPad Prism 6.0 software, and the EC50 value was calculated.
