Description

Technical Field

[0001] This invention belongs to the field of pharmaceuticals, specifically relating to a compound as a thyroid hormone β-receptor agonist and its use, and further relating to pharmaceutical compositions comprising said compound. This invention further relates to the use of said compound and pharmaceutical compositions in the preparation of medicaments for the prevention, treatment, or relief of diseases regulated by thyroid hormone β-receptors, particularly in the preparation of medicaments for the treatment of non-alcoholic fatty liver disease. Background Technology

[0002] Thyroid hormones (TH) play a crucial role in growth, differentiation, development, and maintaining metabolic homeostasis. TH is synthesized by the thyroid gland and secreted into the circulatory system primarily in two forms: triiodothyronine (T3) and tetraiodothyronine (T4). Although T4 is the predominant form secreted by the thyroid, T3 is the physiologically more active form. T4 is converted to T3 by tissue-specific deiodinases, which are present in all tissues, but are primarily found in the liver and kidneys.

[0003] The physiological functions of thyroid hormone (TH) are primarily mediated through the thyroid hormone receptor (TR). TR belongs to the nuclear receptor superfamily and is a T3-induced transcription factor, playing a central role in mediating T3's action. TR is mainly located in the cell nucleus, forming heterodimers with the retinoid X receptor (RXR) and other nuclear receptors to bind to the thyroid hormone response element (TRE) in the promoter region of target genes, thereby regulating gene transcription. There are two subtypes of TR: TRα and TRβ. TRα can be further divided into TRα1 and TRα2, and TRβ into TRβ1 and TRβ2. Only TRα1, TRβ1, and TRβ2 can bind to the T3 ligand. TRα mainly regulates heart rate, while TRβ plays a crucial role in controlling hepatic cholesterol metabolism and inhibiting thyroid-stimulating hormone (TSH) release, which may be related to the high expression of TRβ in the liver and pituitary gland.

[0004] If side effects can be minimized or eliminated, then thrombocytopenia (TH) has certain therapeutic benefits (Paul M. Yenet. al. Physiological Reviews, Vol. 81(3):pp. 1097-1126 (2001); Paul Webbet. al. Expert Opin. Investig. Drugs, Vol. 13(5):pp. 489-500 (2004)). For example, TH can increase metabolic rate, oxygen consumption, and heat production, thereby reducing body weight. Weight loss will improve obesity-related comorbidities and has beneficial effects on obese patients, and may also have beneficial effects on glycemic control in obese patients with type 2 diabetes.

[0005] Th can also lower serum low-density lipoprotein (LDL) (Eugene Morkin et al. Journal of Molecular and Cellular Cardiology, Vol. 37: pp. 1137-1146 (2004)). Hyperthyroidism has been found to be associated with low total serum cholesterol, which is attributed to TH increasing hepatic LDL receptor expression and stimulating cholesterol metabolism to bile acids (JJ. Abrams et al. J. Lipid Res., Vol. 22: pp. 323-38 (1981)). Hypothyroidism is associated with hypercholesterolemia, and there are reports of TH replacement therapy lowering total cholesterol (M. Aviramet. al. Clin. Biochem., Vol. 15: pp. 62-66 (1982); JJ. Abrams et al. J. Lipid Res., Vol. 22: pp. 323-38 (1981)). In animal models, TH has shown beneficial effects in increasing HDL cholesterol and improving the conversion rate of LDL to HDL by increasing the expression of apo A-1 (one of the major apoproteins of HDL) (Gene C. Ness et al. Biochemical Pharmacology, Vol. 56: pp. 121-129 (1998); GJ. Grover et al. Endocrinology, Vol. 145: pp. 1656-1661 (2004); GJ. Grover et al. Proc. Natl. Acad. Sci. USA, Vol. 100: pp. 10067-10072 (2003)). The incidence of atherosclerotic vascular disease is directly related to LDL cholesterol levels, and through its regulatory effects on LDL and HDL, TH may also reduce the risk of atherosclerosis and other cardiovascular diseases. In addition, there is evidence that TH lowers lipoprotein(a), an important risk factor that is elevated in patients with atherosclerosis (Paul Webb et al. Expert Opin. Investig. Drugs, Vol. 13(5): pp. 489-500 (2004); de Bruin et al. J. Clin. Endo. Metab., Vol. 76: pp. 121-126 (1993)).

[0006] Th is also a key signaling agent for oligodendrocyte differentiation and myelination during development, and it stimulates myelin regeneration in an adult model of multiple sclerosis (MS) (Calza et al., Brain Res Revs 48:339-346, 2005). However, due to the limited therapeutic window for achieving myelin regeneration while avoiding cardiotoxicity and bone demineralization associated with chronic hyperthyroidism, thrombolysis cannot be used for long-term treatment. Some thrombolysis analogs can activate thrombolysis-responsive genes while avoiding the associated drawbacks of thrombolysis by utilizing the molecular and physiological characteristics of the thrombolysis receptor (Malm et al. Mini Rev Med Chem 7:79-86, 2007).

[0007] In addition, non-alcoholic fatty liver disease (NAFLD) is also closely related to thrombocytopenic purpura (TH). On the one hand, NAFLD affects the conversion and inactivation of TH, leading to a decrease in serum TH levels; on the other hand, the decrease in TH levels further causes lipid metabolism disorders and glucose metabolism disorders, participating in the occurrence of NAFLD. Studies have shown that fatty liver formation in rats induced by a choline-methionine-deficient diet can be reversed after feeding them T3 (Perra A, et al. Faseb, 2008, 22(8):2981).

[0008] However, endogenous thyroxine (TH) is non-selective and has side effects, such as hyperthyroidism, particularly cardiovascular toxicity. Therefore, the development of TH analogs (e.g., thyroid hormone beta-agonists) that avoid the adverse effects of hyperthyroidism while maintaining the beneficial effects of TH will open new avenues for treating patients with conditions such as obesity, hyperlipidemia, hypercholesterolemia, diabetes, hepatic steatosis, non-alcoholic fatty liver disease, atherosclerosis, cardiovascular disease, hypothyroidism, thyroid cancer, thyroid disorders, and related conditions and diseases.

Specific examples of N-oxides are N-oxides of tertiary amines or N-oxides of nitrogen-containing heterocyclic nitrogen atoms. The corresponding amines can be treated with oxidizing agents such as hydrogen peroxide or peracids (e.g., peroxycarboxylic acids) to form N-oxides (see Advanced Organic Chemistry, Wiley Interscience, 4th ed., Jerry March, pages). In particular, N-oxides can be prepared using the LWDeady method (Syn. Comm. 1977, 7, 509-514), in which the amine compound is reacted with m-chloroperbenzoic acid (MCPBA) in an inert solvent, such as dichloromethane.

[0099] Any asymmetric atom (e.g., carbon, etc.) in the compounds of the present invention may exist in a racemic or enantiomerically enriched form, such as (R)-, (S)-, or (R,S)- configuration. In some embodiments, each asymmetric atom has at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 99% enantiomeric excess in the (R)- or (S)- configuration. If possible, substituents on atoms having unsaturated double bonds may be present in cis-(Z)- or trans-(E)- form.

[0100] Therefore, as described in this invention, the compounds of this invention can exist in the form of one of the possible isomers, rotational isomers, tautomers, tautomers, or mixtures thereof, for example, in the form of essentially pure geometric (cis or trans) isomers, diastereomers, optical isomers (enantiomers), racemates, or mixtures thereof.

[0101] Any mixture of isomers can be separated into pure or substantially pure geometric or optical isomers, diastereomers, and racemates based on the physicochemical differences of the components, for example by chromatography and / or stepwise crystallization.

[0102] Racemates of any resulting end product or intermediate can be separated into optical enantiomers using known methods, such as by separating their diastereomeric salts. Racemate products can also be separated by chiral chromatography, such as high-performance liquid chromatography (HPLC) using chiral adsorbents. In particular, enantiomers can be prepared by asymmetric synthesis (e.g., Jacques, et al., Enantiomers, Racemates and Resolutions (Wiley Interscience, New York, 1981); Principles of Asymmetric Synthesis (2 ndEd. Robert E. Gawley, Jeffrey Aubé, Elsevier, Oxford, UK, 2012); Eliel, EL Stereochemistry of Carbon Compounds (McGraw-Hill, NY, 1962); and Wilen, SHTables of Resolving Agents and Optical Resolutions p. 268 (EL Eliel, Ed., Univ. of Notre Dame Press, Notre Dame, IN 1972)).

[0103] This invention also includes isotopically labeled compounds of the invention that are identical to those compounds described herein except that one or more atoms are replaced by atoms with atomic masses or mass numbers different from those of naturally occurring common atoms. Exemplary isotopes that may also be introduced into the compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine, such as... 2 H, 3 H, 13 C, 14 C, 15 N, 16 O, 17 O, 31 P, 32 P, 36 S, 18 F and 37 Cl.

[0104] Compounds of the present invention comprising other isotopes of the aforementioned isotopes and / or other atoms, as well as pharmaceutically acceptable salts of said compounds, are included within the scope of this invention. Isotope-labeled compounds of the present invention, such as radioactive isotopes, are also included. 3 H and 14 The incorporation of tritium into the compounds of this invention can be used for drug and / or substrate tissue distribution analysis. Due to its ease of preparation and detection, tritium-substituted compounds, i.e., 3 H, and carbon-14, i.e. 14 C isotopes are particularly preferred. Additionally, isotopes with higher mass numbers, such as deuterium, are used. 2 H substitution can offer therapeutic advantages such as greater metabolic stability, including increased in vivo half-life or reduced dose requirements. Therefore, it may be preferred in some situations.

[0105] The stereochemical definitions and conventions used in this invention are generally in accordance with those described in S.P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984), McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., “Stereochemistry of Organic Compounds,” John Wiley & Sons, Inc., New York, 1994. The compounds of this invention may contain asymmetric or chiral centers and thus exist in different stereoisomeric forms. It is contemplated that all stereoisomeric forms of the compounds of this invention, including but not limited to diastereomers, enantiomers, and atropisomers, and mixtures thereof such as racemic mixtures, are also included within the scope of this invention. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. When describing optically active compounds, the prefixes D and L or R and S are used to indicate the absolute configuration of the molecule with respect to the chiral centers (or multiple chiral centers) in the molecule. The prefixes d and l, or (+) and (–), are symbols used to specify the plane-polarized rotation of light caused by a compound, where (–) or l indicates that the compound is levorotatory. Compounds with the prefix (+) or d are dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of each other. Specific stereoisomers may also be called enantiomers, and mixtures of such isomers are generally called mixtures of enantiomers. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which may occur when there is no stereoselectivity or stereospecificity in a chemical reaction or method.

[0106] Depending on the choice of raw materials and methods, the compounds of this invention can exist as one or a mixture of possible isomers, for example, as pure optical isomers, or as mixtures of isomers, such as as racemic and non-corresponding isomer mixtures, depending on the number of asymmetric carbon atoms. Optically active (R)- or (S)- isomers can be prepared using chiral synthons or chiral formulations, or resolved using conventional techniques. If the compound contains a double bond, the substituent may be E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the cycloalkyl substituent may be cis or trans (cis- or trans-) configuration.

[0107] Unless otherwise stated, the structures described in this invention also represent all isomers (e.g., enantiomers, diastereomers, atropisomers, and geometric (or conformations)) including this structure; for example, R and S configurations of each asymmetric center, (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers. Therefore, individual stereochemical isomers of the compounds of this invention, as well as mixtures of enantiomers, diastereomers, and geometric isomers (or conformations) are all within the scope of this invention.

[0108] The terms "tautomer" or "tautomer form" refer to structural isomers with different energies that can interconvert through a low energy barrier. If tautomerism is possible (e.g., in solution), chemical equilibrium can be achieved in the tautomer. For example, proton tautomers (also called prototropic tautomers) involve interconversions via proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers involve interconversions via the rearrangement of some bonding electrons. A specific example of a keto-enol tautomer is the interconversion between pentane-2,4-dione and 4-hydroxypent-3-en-2-one. Another example of tautomerism is phenol-keto tautomerism. A specific example of a phenol-keto tautomer is the interconversion between pyridin-4-ol and pyridin-4(1H)-keto. Unless otherwise indicated, all tautomeric forms of the compounds of the invention are within the scope of the invention.

[0109] The term "geometric isomers," also known as "cis-trans isomers," refers to isomers that cannot rotate freely due to the double bond (including the double bond, C=N double bond, and N=N double bond in alkenes) or the single bond of a cyclic carbon atom.

[0110] As used in this invention, the term "test subject" refers to an animal. Typically, the animal is a mammal. Test subjects also refer to primates (e.g., humans), cattle, sheep, goats, horses, dogs, cats, rabbits, rats, mice, fish, birds, etc. In some embodiments, the test subject is a primate. In other embodiments, the test subject is a human.

[0111] The terms "recipient" and "patient" as used in this invention are used interchangeably. The terms "recipient" and "patient" refer to animals (e.g., birds such as chickens, quails, or turkeys) or mammals, particularly "mammals" including non-primates (e.g., cattle, pigs, horses, sheep, rabbits, guinea pigs, rats, cats, dogs, and mice) and primates (e.g., monkeys, chimpanzees, and humans), and more specifically, humans. In one embodiment, the recipient is a non-human animal, such as livestock (e.g., horses, cattle, pigs, or sheep) or a pet (e.g., dogs, cats, guinea pigs, or rabbits). In other embodiments, "patient" refers to a human.

[0112] In addition, unless otherwise indicated, the structural formulas of the compounds described in this invention comprise enriched isotopes of one or more different atoms.

[0113] As used in this invention, the term "treatment" refers to any disease or condition, and in some embodiments, it means improving the disease or condition (i.e., slowing down or stopping or alleviating the development of the disease or at least one of its clinical symptoms). In other embodiments, "treatment" means alleviating or improving at least one bodily parameter, including bodily parameters that may not be perceived by the patient. In still other embodiments, "treatment" means regulating the disease or condition physically (e.g., stabilizing perceptible symptoms) or physiologically (e.g., stabilizing bodily parameters) or both. In still other embodiments, "treatment" means preventing or delaying the onset, occurrence, or worsening of the disease or condition.

[0184] The pharmaceutical compositions of the present invention can be administered directly or in the form of a pharmaceutical composition or drug, as is well known in the art. The treatment methods of the present invention may comprise administration of an effective compound of the present invention to an individual in need. In some embodiments, the individual is a mammalian individual, and in other embodiments, the individual is a human individual.

[0185] The effective amount of the compounds, pharmaceutical compositions, or drugs described in this invention can be easily determined by conventional methods, and the most effective and convenient route of administration and the most suitable formulation can also be determined by conventional methods.

[0186] The compounds or compositions of the present invention can be administered by any suitable means, and can be given to humans or other animals orally, rectally, parenterally, intracerebrospinal, vaginally, intraperitoneally, topically (such as by powder, ointment or drops), or nasal spray, depending on the severity of the disease.

[0187] Oral liquid dosage forms include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compound, liquid dosage forms may contain inert diluents commonly used in the art, such as water or other solvents, solubilizers, and emulsifiers, such as ethanol, isopropanol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butanediol, dimethylformamide, oils (especially cottonseed oil, peanut oil, corn oil, germ oil, olive oil, castor oil, and sesame oil), glycerin, tetrahydrofurfuryl alcohol, polyethylene glycol, and fatty acid esters of sorbitan, and mixtures thereof. In addition to inert diluents, oral compositions may also include adjuvants, such as humectants, emulsifiers and suspending agents, sweeteners, flavoring agents, and aroma enhancers.

[0188] Injectable formulations can be formulated using suitable dispersants or wetting agents and suspending agents according to known techniques, such as sterile injectable aqueous or oil suspensions. Sterile injectable formulations may also be sterile injectable solutions, suspensions, or emulsions in non-toxic, parenteral-acceptable diluents or solvents, such as solutions in 1,3-butanediol. Among acceptable media and solvents, water, Ringer's solution, and isotonic sodium chloride solution are acceptable. Additionally, sterile non-volatile oils are conventionally used as solvents or suspension media. For this purpose, any odorless non-volatile oil can be used, including synthetic monoglycerides or diglycerides. Furthermore, fatty acids, such as octadecenoic acid, are used in the preparation of injectable formulations.

[0189] For example, injectable formulations can be sterilized by filtering with a bacterial retention filter or by adding a sterilizing agent, which is soluble or dispersed in sterile water or other sterile injectable media in the form of a sterile solid composition, before use.

[0190] To prolong the effect of the compounds or compositions described in this invention, it is often desirable to slow the absorption of the compound by subcutaneous or intramuscular injection. This can be achieved by using liquid suspensions of poorly water-soluble crystals or amorphous substances. The absorption rate of the compound then depends on its dissolution rate, which in turn depends on the crystal size and crystal form. Alternatively, delayed absorption of parenterally administered compounds can be achieved by dissolving or suspending the compound in an oil medium. Injectable storage forms are prepared by forming a microcapsule matrix of the compound in a biodegradable polymer, such as polylactide-polyglycolic acid. The release rate of the compound can be controlled depending on the ratio of compound to polymer and the properties of the specific polymer used. Examples of other biodegradable polymers include polyorthoesters and polyanhydrides. Injectable storage formulations can also be prepared by retaining the compound in liposomes or microemulsions that are compatible with body tissues.
