Abstract

The invention relates to a ROR gamma antagonist compound, which is a compound shown as a formula (I). The compounds or pharmaceutical compositions can be used to modulate retinoic acid-related orphan receptor gamma t (ROR γ t). The invention also relates to methods for preparing such compounds and pharmaceutical compositions, and their use in the treatment or prevention of inflammatory or autoimmune diseases mediated by roryt in mammals, particularly humans.

Description

ROR gamma antagonist and application thereof in medicine
Technical Field
The invention belongs to the technical field of medicines, and particularly relates to a small molecular compound, a composition, a preparation method and application thereof, wherein the compound or the composition can be used as an antagonist of retinoic acid-related orphan receptor gamma t (ROR gamma t) and is used for preventing or treating diseases related to immunity.
Background
Retinoic acid-related nocosomal receptors are a subfamily of transcription factors in the steroid hormone nuclear receptor superfamily. The family of retinoic acid-related orphan nuclear receptors includes ROR α, ROR β, and ROR γ, each encoded by a distinct gene (RORA, RORB, and RORC). Retinoic acid-related orphan nuclear receptors contain four major domains: an N-terminal A/B domain, a DNA binding domain, a hinge domain, and a ligand binding domain.
Retinoic acid-related orphan receptor gamma t (ROR γ t) is one of two isoforms of retinoic acid-related orphan receptor gamma (ROR γ), and may also be referred to as ROR γ 2. It has been shown that ROR γ t is expressed only in lymphoid lineage and embryonic lymphoid tissue inducer cells (Sun et al, Science 288:2369-2372, 2000; Eberl et al, Nat Immunol.5:64-73,2004). ROR gamma T, a characteristic transcription factor of helper T cells (Th17), plays an important role in Th17 cell differentiation, and is a key regulator of Th17 cell differentiation (Ivanov, II, McKenzie BS, Zhou L, Tadokoro CE, Lepelley A, Lafaille JJ, et al. cell 2006; 126(6): 1121-33).
Th17 can secrete interleukin 17 (IL-17) and other proinflammatory cytokines, and has important significance in autoimmune diseases and body defense response. IL-17 is a proinflammatory cytokine for inflammatory progression and various autoimmune diseases, and is closely associated with a variety of autoimmune and inflammatory diseases, such as rheumatoid arthritis, psoriasis, psoriatic arthritis, spondyloarthritis, asthma, inflammatory bowel disease, systemic lupus erythematosus, and multiple sclerosis, among others (Jetten et al, Nucl. Recept. Signal,2009,7: e 003; Manel et al, Nat. Immunol.,2008,9, 641-649).
The role ROR γ t plays in the pathogenesis of autoimmune diseases or inflammation has been extensively studied and fully elucidated (Jetten et al, adv. Dev. biol., 2006,16: 313-supplement 355; Meier et al Immunity,2007,26: 643-654; Aloisi et al, Nat. Rev. Immunol.,2006,6: 205-supplement 217; Jager et al., J. Immunol.,2009,183: 7169-supplement 7177; Barnes et al, Nat. Rev. Immunol.,2008,8: 183-supplement 192). Therefore, inhibition of ROR γ t will effectively inhibit cell differentiation of Th17, regulate the production and secretion levels of IL-17 and other proinflammatory cytokines, thereby modulating the body's immune system, treating immune and inflammatory diseases associated with ROR γ t regulation.

Detailed description of the invention
Definitions and general terms
Reference will now be made in detail to certain embodiments of the invention, examples of which are illustrated by the accompanying structural and chemical formulas. The invention is intended to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims. Those skilled in the art will recognize that many methods and materials similar or equivalent to those described herein can be used in the practice of the present invention. The present invention is in no way limited to the methods and materials described herein. In the event that one or more of the incorporated documents, patents, and similar materials differ or contradict this application (including but not limited to defined terminology, application of terminology, described techniques, and the like), this application controls.
It will be further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications referred to herein are incorporated by reference in their entirety.
The following definitions as used herein should be applied unless otherwise indicated. For the purposes of the present invention, the chemical elements are in accordance with the CAS version of the periodic Table of the elements, and the handbook of chemistry and Physics, 75 th edition, 1994. In addition, general principles of Organic Chemistry can be referred to as described in "Organic Chemistry", Thomas Sorrell, University Science Books, Sausaltito: 1999, and "March's Advanced Organic Chemistry" by Michael B.Smith and Jerry March, John Wiley & Sons, New York:2007, the entire contents of which are incorporated herein by reference.
The articles "a," "an," and "the" as used herein are intended to include "at least one" or "one or more" unless otherwise indicated or clearly contradicted by context. Thus, as used herein, the articles refer to articles of one or more than one (i.e., at least one) object. For example, "a component" refers to one or more components, i.e., there may be more than one component contemplated for use or use in embodiments of the described embodiments.
The term "subject" as used herein refers to an animal. Typically the animal is a mammal. Subjects, e.g., also primates (e.g., humans, males or females), cows, sheep, goats, horses, dogs, cats, rabbits, rats, mice, fish, birds, etc. In certain embodiments, the subject is a primate. In other embodiments, the subject is a human.
The term "patient" as used herein refers to humans (including adults and children) or other animals. In some embodiments, "patient" refers to a human.
The term "comprising" is open-ended, i.e. includes the elements indicated in the present invention, but does not exclude other elements.
"stereoisomers" refers to compounds having the same chemical structure but differing in the arrangement of atoms or groups in space. Stereoisomers include enantiomers, diastereomers, conformers (rotamers), geometric isomers (cis/trans), atropisomers, and the like.
"chiral" is a molecule having the property of not overlapping its mirror image; and "achiral" refers to a molecule that can overlap with its mirror image.
"enantiomer" refers to two isomers of a compound that are not overlapping but are in mirror image relationship to each other.
"diastereomer" refers to a stereoisomer having two or more chiral centers and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting points, boiling points, spectral properties, and reactivities. Mixtures of diastereomers may be separated by high resolution analytical procedures such as electrophoresis and chromatography, e.g., HPLC.
The stereochemical definitions and rules used in the present invention generally follow the general definitions of 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.
Many organic compounds exist in an optically active form, i.e., they have the ability to rotate the plane of plane polarized light. In describing optically active compounds, the prefixes D and L or R and S are used to denote the absolute configuration of a molecule with respect to one or more of its chiral centers. The prefixes d and l or (+) and (-) are the symbols used to specify the rotation of plane polarized light by the compound, where (-) or l indicates that the compound is left-handed. Compounds prefixed with (+) or d are dextrorotatory. A particular stereoisomer is an enantiomer and a mixture of such isomers is referred to as an enantiomeric mixture. A50: 50 mixture of enantiomers is referred to as a racemic mixture or racemate, which may occur when there is no stereoselectivity or stereospecificity in the chemical reaction or process.
Any asymmetric atom (e.g., carbon, etc.) of a compound disclosed herein can exist in racemic or enantiomerically enriched forms, such as the (R) -, (S) -or (R, S) -configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in the (R) -or (S) -configuration.
Depending on the choice of starting materials and methods, the compounds of the invention may exist as one of the possible isomers or as mixtures thereof, for example as racemates and diastereomeric mixtures (depending on the number of asymmetric carbon atoms). Optically active (R) -or (S) -isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be in the E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the substituents of the cycloalkyl group may have cis or trans configuration.
Any resulting mixture of stereoisomers may be separated into pure or substantially pure geometric isomers, enantiomers, diastereomers, depending on differences in the physicochemical properties of the components, for example, by chromatography and/or fractional crystallization.
The racemates of any of the resulting end products or intermediates can be resolved into the optical enantiomers by known methods using methods familiar to those skilled in the art, e.g., by separation of the diastereomeric salts obtained. The racemic product can also be isolated by chiral chromatography, e.g., high performance liquid chromatography using a chiral adsorbent (HPLC: column: Chiralpak AD-H (4.6 mm. times.250 mm,5 μm); mobile phase: n-hexane: ethanol 40:60, isocratic elution; flow rate: 1 mL/min). In particular, Enantiomers can be prepared by asymmetric synthesis, for example, see Jacques, et al, Enantiomers, racemes and solutions (Wiley Interscience, New York, 1981); principles of Asymmetric Synthesis (2) nd Ed.Robert E.Gawley,Jeffrey Aubé,Elsevier,Oxford,UK,2012)；Eliel,E.L.Stereochemistry of Carbon Compounds(McGraw-Hill,NY,1962)；Wilen,S.H.Tables of Resolving Agents and Optical Resolutions p.268(E.L.Eliel,Ed.,Univ.of Notre Dame Press,Notre Dame,IN 1972)；Chiral Separation Techniques:A Practical Approach(Subramanian,G.Ed.,Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim,Germany,2007)。
The compounds of the invention may be optionally substituted with one or more substituents, as described herein, in compounds of the general formula above, or as specifically exemplified, sub-classes, and classes of compounds encompassed by the invention.
In general, the term "substituted" means that one or more hydrogen atoms in a given structure are replaced with a particular substituent. Unless otherwise indicated, a substituted group may have one substituent substituted at each substitutable position of the group. When more than one position in a given formula can be substituted with one or more substituents selected from a particular group, the substituents may be substituted at each position, identically or differently.
The term "unsubstituted" means that the specified group bears no substituent.
The term "optionally substituted with … …" is used interchangeably with the term "unsubstituted or substituted with … …", i.e., the structure is unsubstituted or substituted with one or more substituents described herein. Substituents described herein include, but are not limited to, D, oxo (═ O), F, Cl, Br, I, N3、CN、NO2、OH、SH、NH2、S(O)2Carboxyl, aldehyde, alkyl, haloalkyl, alkenyl, alkynyl, alkoxy, haloalkoxy, alkylamino, hydroxyalkyl, alkylenealkoxy, carbocyclyl, cycloalkyl, heterocyclyl, spiroheterocyclyl, fused heterocyclyl, fused cyclyl, aryl, heteroaryl, and the like.
In addition, unless otherwise explicitly indicated, the descriptions of the terms "… independently" and "… independently" and "… independently" used in the present invention are interchangeable and should be understood in a broad sense to mean that the specific items expressed between the same symbols do not affect each other in different groups or that the specific items expressed between the same symbols in the same groups do not affect each other.
In the various parts of this specification, substituents of the disclosed compounds are disclosed in terms of group type or range. It is specifically intended that the invention includes each and every independent subcombination of the various members of these groups and ranges. For example, the term "C1-6Alkyl "means in particular independently disclosed methyl, ethyl, C3Alkyl radical, C4Alkyl radical, C5Alkyl and C6An alkyl group.
In each of the parts of the invention, linking substituents are described. Where the structure clearly requires a linking group, the markush variables listed for that group are understood to be linking groups. For example, if the structure requires a linking group and the markush group definition for the variable recites "alkyl" or "aryl," it is understood that the "alkyl" or "aryl" represents an attached alkylene group or arylene group, respectively.
The term "alkyl" or "alkyl group" as used herein, denotes a saturated straight or branched chain monovalent hydrocarbon radical, wherein the alkyl group may be optionally substituted with one or more substituents as described herein.

Pharmaceutically acceptable solvates of the invention include those in which the crystallization solvent may be isotopically substituted, e.g. D 2O, acetone-d6、DMSO-d6Those solvates of (a).
Pharmaceutical compositions, formulations and administration of the compounds of the invention
The present invention provides a pharmaceutical composition comprising a compound disclosed herein, for example, as set forth in the examples; and a pharmaceutically acceptable excipient, carrier, adjuvant, or combination thereof.
The present invention provides methods of treating, preventing or ameliorating a disease or condition comprising administering a safe and effective amount of a combination comprising a compound of the present disclosure and one or more therapeutically active agents. Wherein the combination comprises one or more additional agents for the prophylaxis or treatment of an inflammatory syndrome, disorder or disease.
The amount of compound in the pharmaceutical composition disclosed herein is effective to detect inhibition of retinoic acid-related nocosomal receptor gamma t in a biological sample or patient. The dosage of the active ingredient in the composition of the present invention may vary, however, the amount of the active ingredient must be such that a suitable dosage form is obtained. The active ingredient may be administered to patients (animals and humans) in need of such treatment at dosages that provide optimal pharmaceutical efficacy. The selected dosage depends on the desired therapeutic effect, on the route of administration and on the duration of the treatment. The dosage will vary from patient to patient depending on the nature and severity of the disease, the weight of the patient, the particular diet of the patient, the concurrent use of drugs, and other factors that will be recognized by those skilled in the art. The dosage range is generally about 0.5mg to 1.0g per patient per day and may be administered in a single dose or in multiple doses. In one embodiment, the dosage range is from about 0.5mg to 500mg per patient per day; from about 0.5mg to 200mg per patient per day in another embodiment; and in yet another embodiment from about 5mg to 50mg per patient per day.
It will also be appreciated that certain compounds of the invention may be present in free form and used in therapy, or if appropriate in the form of a pharmaceutically acceptable derivative thereof. Pharmaceutically acceptable derivatives include pharmaceutically acceptable prodrugs, salts, esters, salts of such esters, or any additional adduct or derivative that upon administration to a patient in need thereof provides, directly or indirectly, a compound of the present invention or a metabolite or residue thereof.
The medicaments or pharmaceutical compositions disclosed herein may be prepared and packaged in bulk (bulk) form, wherein a safe and effective amount of the compound of formula (I) may be extracted and then administered to a patient in the form of a powder or syrup. Typically, the administration is to the patient at a dosage level of between 0.0001 and 10mg/kg body weight per day to achieve effective inhibition of retinoic acid-related nociceptor γ t. Alternatively, the pharmaceutical compositions disclosed herein can be prepared and packaged in unit dosage forms, wherein each physically discrete unit contains a safe and effective amount of a compound of formula (I). When prepared in unit dosage form, the disclosed pharmaceutical compositions can generally contain, for example, from 0.5mg to 1g, or from 1mg to 700mg, or from 5mg to 100mg of the disclosed compounds.
When the pharmaceutical composition of the invention contains one or more other active ingredients in addition to the compound of the invention, the compound weight ratio of the compound of the invention to the second active ingredient may vary and depends on the effective dose of each ingredient. Generally, an effective dose of each is used. Thus, for example, when a compound of the present invention is mixed with another pharmaceutical agent, the weight ratio of the compound of the present invention to the other pharmaceutical agent typically ranges from about 1000: 1 to about 1: 1000, e.g., from about 200: 1 to about 1: 200. Mixtures of the compounds of the invention with other active ingredients are generally also within the above-mentioned ranges, but in each case an effective dose of each active ingredient should be used.
As used herein, "pharmaceutically acceptable excipient" means a pharmaceutically acceptable material, mixture or vehicle, which is compatible with the dosage form or pharmaceutical composition to be administered. Each excipient, when mixed, must be compatible with the other ingredients of the pharmaceutical composition to avoid interactions that would substantially reduce the efficacy of the disclosed compounds and which would result in a pharmaceutical composition that is not pharmaceutically acceptable when administered to a patient. Furthermore, each excipient must be pharmaceutically acceptable, e.g., of sufficiently high purity.
Suitable pharmaceutically acceptable excipients will vary depending on the particular dosage form selected. In addition, pharmaceutically acceptable excipients may be selected for their specific function in the composition. For example, certain pharmaceutically acceptable excipients may be selected to aid in the production of a uniform dosage form. Certain pharmaceutically acceptable excipients may be selected to aid in the production of stable dosage forms. Certain pharmaceutically acceptable excipients may be selected to facilitate carrying or transporting the disclosed compounds from one organ or portion of the body to another organ or portion of the body when administered to a patient. Certain pharmaceutically acceptable excipients may be selected that enhance patient compliance.
Suitable pharmaceutically acceptable excipients include the following types of excipients: diluents, fillers, binders, disintegrants, lubricants, glidants, granulating agents, coating agents, wetting agents, solvents, co-solvents, suspending agents, emulsifiers, sweeteners, flavoring agents, taste masking agents, colorants, anti-caking agents, humectants, chelating agents, plasticizers, viscosity increasing agents, antioxidants, preservatives, stabilizers, surfactants and buffers. The skilled artisan will recognize that certain pharmaceutically acceptable excipients may provide more than one function, and provide alternative functions, depending on how many such excipients are present in the formulation and which other excipients are present in the formulation.
The skilled person is knowledgeable and skilled in the art to enable them to select suitable amounts of suitable pharmaceutically acceptable excipients for use in the present invention. Furthermore, there is a large amount of resources available to the skilled person, who describes pharmaceutically acceptable excipients and is used to select suitable pharmaceutically acceptable excipients.
