Description
Technical Field
The invention belongs to the field of medicaments, and discloses an amide compound with ROR gamma t activity and a bicyclic structure, a preparation method thereof, a pharmaceutical composition containing the compound and application thereof in medicaments.
Background
Retinoic acid receptor-Related Orphan Receptors (RORs) are members of the steroid hormone nuclear receptor superfamily (receptor superfamily). The family includes ROR α, ROR β and ROR γ, ROR γ t, RORs comprise 4 major regions shared by most nuclear receptors, the N-terminal a/B domain, the DNA-binding domain, the hinge domain and the ligand binding domain. Each ROR gene produces a separate subtype, differing only in its N-terminal A/B domain. ROR γ has two subtypes, ROR γ l and ROR γ t. ROR γ 1 is expressed in various tissues such as thymus, muscle and kidney, while ROR γ t is expressed only in a part of immune cells (e.g., Th17 cells) and acts as a transcription factor for IL-17A and IL-17F, and a major regulator of Th17 cell differentiation. Thl7 cells are a subset of T helper cells that preferentially produce the proinflammatory cytokines IL-17A, IL-17F, IL-21 and IL-22. Thl7 cells and their effector molecules (e.g. IL-17, IL-21, IL-22, GM-CSF and CCL20) are involved in the pathogenesis of several autoimmune diseases and inflammatory diseases, and studies have also demonstrated that Th17 cells are involved in the pathogenesis of several autoimmune diseases and inflammatory diseases such as multiple sclerosis, rheumatoid arthritis, psoriasis, asthma, autoimmune diseases and graft-versus-host disease (Jetten et al, nucl. recept. signal,2009,7: e 003; Manel et al, nat. immunol,2008,9, 641-one 649), as well as in the development of inflammation-associated tumors, Th17 cells are activated during the disease process and are responsible for the recruitment of other inflammatory cell types, such as neutrophils, to mediate the pathology of the target tissue (Korn et al, annu. rev. immunol. 2009,27: 485-517). Therefore, drugs having ROR γ t-modulating action are expected to exhibit therapeutic effects on various immune diseases by modulating differentiation and activation of Th17 cells.
The ROR gamma t agonist can promote the differentiation of Th17 cell and enhance the level of proinflammatory cytokines, so as to raise the cytotoxicity of lymphocyte. At the same time, ROR γ T agonists are able to inhibit the production of regulatory T cells which suppress the immune response, and therefore agonists are able to push the balance of the immune response in the direction of activation. ROR γ T agonists are also capable of promoting expression of a range of Co-Stimulatory molecules (Co-Stimulatory molecules) such as CD226, CD27 and 4-1BB (CD137) and inhibiting expression of Co-Inhibitory molecules (Co-Inhibitory molecules) such as PD-1, TIGIT, TIM3, CD73 and LAG3, thereby promoting T cell activation. Studies have shown that ROR γ t agonists are able to inhibit Tumor growth and prolong animal survival by an immune response in a variety of homologous Tumor Models (Syngeneic Tumor Models).
The company Lycera first reported the development of small molecule agonists of ROR γ t, and in 2017, the company Lycera declared the initiation of a phase 1/2a clinical trial to examine the efficacy of the developed ROR γ t agonist LYC-55716 in treating patients with advanced, recurrent, or refractory solid tumors. At present, ROR gamma t agonist has been concerned about anti-tumor, a great deal of research is carried out in the industry, and the IL-17 family provides good target points for tumor treatment in the future is very possible; therefore, ROR gamma t is considered as a new target for developing anti-tumor, anti-inflammatory and autoimmune disease drugs, and can be used as a new way for treating cancers and autoimmune inflammatory diseases.

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" or "comprises" is open-ended, i.e. comprising what is specified in the present invention, but not excluding other aspects.
"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.
"diastereoisomers" are stereoisomers whose pairs or multiple chiral centers 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 separated by chiral chromatography, e.g., by subjectingHigh Performance Liquid Chromatography (HPLC) with chiral adsorbents. 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:APractical Approach(Subramanian,G.Ed.,Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim,Germany,2007)。
The term "tautomer" or "tautomeric form" refers to structural isomers having different energies that can interconvert by a low energy barrier (low energy barrier). If tautomerism is possible (e.g., in solution), then the chemical equilibrium of the tautomer can be reached. For example, proton tautomers (also known as proton transfer tautomers) include interconversions by proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers (valenctautomers) include interconversion by recombination of some of the bonding electrons. A specific example of keto-enol tautomerism is the tautomerism of the pentan-2, 4-dione and 4-hydroxypent-3-en-2-one tautomers. Another example of tautomerism is phenol-ketone tautomerism. One specific example of phenol-ketone tautomerism is the tautomerism of pyridin-4-ol and pyridin-4 (1H) -one tautomers. Unless otherwise indicated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
The terms "optional," "optionally," or "optionally" mean that the subsequently described event or circumstance may, but need not, occur, i.e., that the description includes instances where said event or circumstance occurs and instances where it does not. For example, "optionally substituted with 1,2,3, or 4 …" includes the case where the group is substituted with 1, or 2, or 3, or 4 of the substituents described, as well as the case where the group is not substituted with the substituents described. Further, when the group is substituted with 1 or more of the substituents, the substituents are independent of each other, that is, the 1 or more substituents may be different from each other or the same; or "optionally salified with a suitable acid" includes salification of the compound with a suitable acid or without any acid, and may optionally salify in a ratio of 1:1, or 1:1.5, or 1:2, or 1:3, or 2:1, or 3: 1.
The compounds of the invention may be independently optionally substituted with one or more substituents, as described herein, in the general formula above, or as specified in the examples, subclasses, and classes of compounds encompassed by the invention. It will be understood that the term "optionally substituted", "optionally substituted with … …", or "optionally including" is used interchangeably with the term "substituted or unsubstituted". The term "independently optionally" is used interchangeably with the term "optionally independently", and generally speaking, the term "independently optionally" whether or not preceded by the term "substituted" indicates that one or more hydrogen atoms in a given structure may be substituted or unsubstituted with the particular substituent 1. Unless otherwise indicated, an optional substituent group may be substituted with a substituent 1 at each substitutable, reasonable position of the group. When more than one position in a given formula can be substituted with one or more substituents 1 selected from a particular group, the substituents can be substituted identically or differently at each of the possible positions in the formula. Wherein said substituent 1 may be, but is not limited to: hydrogen, deuterium, oxo, fluoro, chloro, bromo, iodo, hydroxy, amino, carboxy, alkyl-S (═ O)z-, haloalkyl, hydroxyalkyl, aminoalkyl, aldehyde group, aminoacyl, alkoxy, alkylamino, alkylthio, alkanoyl, haloalkoxy, cyano, aryl, heteroaryl, alkenyl, alkynyl, heterocyclic, mercapto, nitro, aryloxy, hydroxyalkoxy, alkyl- (C ═ O) -, benzyl, cycloalkyl, alkylamino-C (═ O) -, CN-alkyl-C (═ O) -, alkyl-O-C (═ O) -alkyl, ester group, hydroxyalkanoyl, or alkoxyalkyl, and the like.

Wherein said substituent 2 may be, but is not limited to: hydrogen, oxo, fluoro, chloro, bromo, iodo, hydroxy, amino, carboxy, alkyl-S (═ O)z-, haloalkyl, hydroxyalkyl, aminoalkyl, aldehyde group, aminoacyl, alkoxy, alkylamino, alkylthio, haloalkoxy, cyano, aryl, heteroaryl, alkenyl, alkynyl, cycloalkyl, heterocyclyl, mercapto, nitro, aryloxy, hydroxyalkoxy, alkyl- (C ═ O) -, benzyl, alkylamino-C (═ O) -, CN-alkyl-C (═ O) -, alkyl-O-C (═ O) -alkyl, ester group, hydroxyalkanoyl, or alkoxyalkyl, and the like. Wherein z is 0, 1, or 2.
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.

Formulations of the present invention include those suitable for oral, nasal, topical, buccal, sublingual, rectal, vaginal and/or parenteral administration. The formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. The amount of active ingredient that can be combined with the carrier materials to produce a single dosage form is generally that amount of the compound which produces a therapeutic effect. Generally, the amount is from about 1% to about 99% active ingredient, preferably from about 5% to about 70%, most preferably from about 10 to about 30%, in units of one percent.
The methods of making these formulations or compositions include the step of bringing into association a compound of the invention with a carrier, optionally and independently one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the compounds of the invention with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product.
Formulations of the present invention suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored base, typically sucrose and acacia or tragacanth), powders, granules, or solutions or suspensions in aqueous or non-aqueous liquids, or oil-in-water or water-in-oil liquid emulsions, or elixirs or syrups, or pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or mouthwashes and the like, each containing a predetermined amount of a compound of the present invention as the active ingredient.

In addition to inert diluents, the oral compositions can also include adjuvants (adjuvants) such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents.
Suspensions, in addition to the active compounds, may contain co-excipients, for example ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.
Formulations of the pharmaceutical compositions of the present invention for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing one or more compounds of the present invention with one or more suitable non-irritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or salicylate, and which is solid at room temperature but liquid at body temperature and will therefore melt in the rectum or vaginal cavity and release the active compound.
Formulations of the invention suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate.
Dosage forms for topical or transdermal administration of the compounds of the invention include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active ingredient may be mixed under sterile conditions with a pharmaceutically acceptable carrier and any preservatives, buffers, or propellants which may be required.
Ointments, pastes, creams and gels may contain, in addition to an active compound of the invention, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.
Powders and sprays can contain, in addition to a compound of the invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder or mixtures of these substances. Sprays can also contain conventional propellants such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.
Transdermal patches have the additional advantage of providing controlled delivery of the compounds of the present invention to the body. Such dosage forms may be prepared by dissolving or dispersing the compound in a suitable vehicle. Absorption enhancers may also be used to increase the flux of compounds through the skin. The rate of flow of such compounds can be controlled by providing a rate controlling membrane or dispersing the active compound in a polymer matrix or gel.
Also included within the scope of the present invention are ophthalmic formulations, ophthalmic ointments, powders, solutions, and the like.
Pharmaceutical compositions of the invention suitable for parenteral administration comprise one or more compounds of the invention in combination with one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the recipient or suspending or thickening agents.
Examples of suitable aqueous and nonaqueous carriers that can be used in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Suitable fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.
These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Prevention of the action of microorganisms can be ensured by including various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like in the compositions. In addition, prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.
In some cases, in order to prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be achieved by using a liquid suspension of crystalline or amorphous material which is poorly water soluble. Thus, the rate of absorption of the drug will depend on its rate of dissolution, which in turn may depend on crystal size and crystal form. Alternatively, prolonged absorption of a parenterally administered drug form is achieved by dissolving or suspending the drug in an oily matrix.
Injectable depot forms are prepared by forming a microencapsulated matrix of the drug in a biodegradable polymer such as polylactide-polyglycolide. Depending on the ratio of drug to polymer and the nature of the particular compound used, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly (orthoesters) and poly (anhydrides). Injectable depot formulations can also be prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.
The formulations of the present invention may be administered orally, parenterally, topically or rectally. They are of course administered in a form suitable for the respective route of administration. For example, they are administered in the form of tablets or capsules, by injection, inhalation, ophthalmic lotion, ointment, suppository and the like, by injection, infusion or inhalation; topically applied by lotion or ointment; administered rectally by means of suppositories. Oral and/or intravenous administration is preferred.

Biological Activity assay for Compounds of the invention
ROR gamma t protein receptor binding assay
1. The experimental principle is as follows:
ROR-gamma t agonist activity screening ROR-gamma t protein receptor binding assays were used. In the experimental system, a ROR-gamma t-LBD protein band GST label (RORgt-LBD-GST), a SRC coactivated protein band biotin label (SRC-biotin), a Eu-labeled anti-GST antibody (Europium anti-GST) is used for binding RORgt-LBD-GST, and D2-labeled Streptavidin (Streptavidin-D2) is used for binding SRC-biotin. When the compound can effectively bind to ROR-gamma t-LBD and cause the change of configuration, thereby enhancing the recruitment of SRC, due to the close distance between ROR-gamma t-LBD and SRC, under the excitation condition of excitation light, energy can be transferred from donor Eu to acceptor D2, thereby generating stronger TR-FRET signal. Conversely, when the compound is not effective in promoting ROR-gamma t-LBD recruitment to SRC, energy is not transferred from the donor Eu to the acceptor D2, and the TR-FRET signal is detected to be weak. According to the experimental principle, the activation effect of the compound on ROR-gamma t can be indirectly judged through the strength of a TR-FRET signal, so that the aim of screening effective compounds is fulfilled.
