FIELD OF THE INVENTION

This invention relates to modulators of the retinoid-related orphan receptor RORy and methods for using such modulators. The compounds described herein can be particularly useful for diagnosing, preventing, or treating a variety of diseases and disorders in humans and animals. Exemplary disorders include, but are not limited to, psoriasis, rheumatoid arthritis, inflammatory bowel disease, Crohn's disease, ulcerative colitis, acute graft-versus-host disease, psoriatic arthritis, ankylosing spondylitis and multiple sclerosis.

BACKGROUND OF THE INVENTION

The retinoid-related orphan receptors RORa, RORp, and RORy play an important role in numerous biological processes including organ development, immunity, metabolism, and circadian rhythms. See, for example, Dussault et al. in Mech. Dev.

(1998) vol. 70, 147-153; Andre et al. in EMBO J. (1998) vol. 17, 3867-3877; Sun et al. in Science (2000) vol. 288, 2369-2373; and Jetten in Nucl. Recept. Signal. (2009) vol. 7, 1 - 32 .

RORy is expressed in several tissues including the thymus, kidney, liver, and muscle. Two isoforms of RORy have been identified: RORyl and RORy2 (also known, respectively, as RORy and RORyt). See, for example, Hirose et al. in Biochem. Biophys. Res. Commun. (1994) vol. 205, 1976-1983; Oritz et al. in Mol. Endocrinol. (1995) vol. 9, 1679-1691 ; and He et al. in Immunity (1998) vol. 9, 797-806. Expression of RORyt is restricted to lymphoid cell types including CD4+CD8+ thymocytes, IL-17 producing T helper (Thl 7) cells, lymphoid tissue inducer (LTi) cells, and γδ cells. RORyt is essential for the development of lymph nodes and Peyer's patches and for the normal

differentiation of Thl7, γδ, and LTi cells. See, for example, Sun et al. in Science (2000) vol. 288, 2369-2373; Ivanov et al. in Cell (2006) vol. 126, 1121-1133; Eberl et al. in Nat. Immunol. (2004) vol. 5, 64-73; Ivanov et al. in Semin. Immunol. (2007) vol. 19, 409-417; and Cua and Tato in Nat. Rev. Immunol. (2010) vol. 10, 479-489.

Proinflammatory cytokines such as IL-17A (also referred to as IL-17), IL-17F, and IL-22 produced by Thl7 cells and other RORy+ lymphocytes activate and direct the immune response to extracellular pathogens. See, for example, Ivanov et al. in Semin. Immunol. (2007) vol. 19: 409-417; and Marks and Craft in Semin. Immunol. (2009) vol. 21, 164-171. RORy directly regulates IL-17 transcription and disruption of RORy in mice attenuates IL-17 production. See, for example, Ivanov et al. in Cell (2006) vol. 126, 1121- 1133.

Dysregulated production of IL-17 has been implicated in several human autoimmune and inflammatory diseases including multiple sclerosis, rheumatoid arthritis, psoriasis, inflammatory bowel disease (IBD), and asthma. See, for example, Lock et al. in Nat. Med. (2002) vol. 8, 500-508; Tzartos et al. in Am. J. Pathol. (2008) vol. 172, 146- 155; Kotake et al. in J. Clin. Invest. (1999) vol. 103, 1345-1352; Kirkham et al. in

Arthritis Rheum. (2006) vol. 54, 1122-1131; Lowes et al. in J. Invest. Dermatol. (2008) vol. 128, 1207-1211; Leonardi et al. in N. Engl. J. Med. (2012) vol. 366, 1190-1199; Fujino et al. in Gut (2003) vol. 52, 65-70; Seiderer et al. in Inflamm. Bowel Dis. (2008) vol.14, 437-445; Wong et al. in Clin. Exp. Immunol. (2001) vol. 125, 177-183; and Agache et al. in Respir. Med. (2010) 104: 1131-1137. In murine models of these diseases, inhibition of IL-17 function by neutralizing antibodies or genetic disruption of IL-17 or IL-17 receptor ameliorates the disease course or clinical symptoms. See, for example, Hu et al. in Ann. N.Y. Acad. Sci. (2011) vol. 1217, 60-76.

Disruption of RORy in mice also attenuates disease progression or severity in animal models of autoimmunity and inflammation including experimental autoimmune encephalomyelitis (EAE), imiquimod induced psoriasis, colitis, and allergic airway disease. See, for example, Ivanov et al. in Cell (2006) vol. 126, 1121-1133; Yang et al. in Immunity (2008) vol. 28, 29-39; Pantelyushin et al. in J. Clin. Invest. (2012) vol. 122, 2252-2256; Leppkes et al. in Gastroenterology (2009) vol. 136, 257-267; and Tilley et al. in J. Immunol. (2007) vol. 178, 3208-3218.

Each of the references in this Background section is hereby incorporated herein by reference in its entirety for all purposes. Therapeutic agents exist to treat a variety of inflammatory and autoimmune diseases, but there still remains a significant unmet medical need in these therapeutic areas. Given the role of IL-17 in human disease and the validation of IL-17 and RORy as targets in murine disease models, compounds capable of modulating RORyt activity are contemplated to provide a therapeutic benefit in the treatment of multiple immune and inflammatory disorders.

The following are definitions of terms used in this specification and appended claims. The initial definition provided for a group or term herein applies to that group or term throughout the specification and claims, individually or as part of another group, unless otherwise indicated.

Compounds of this invention may have one or more asymmetric centers. Unless otherwise indicated, all chiral (enantiomeric and diastereomeric) and racemic forms of compounds of the present invention are included in the present invention. Many geometric isomers of olefins, C=N double bonds, and the like can also be present in the compounds, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. The present compounds can be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. All chiral (enantiomeric and diastereomeric) and racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomer form is specifically indicated.

When any variable (e.g., R ³ ) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R ³ , then said group may optionally be substituted with up to two R ³ groups and R ³ at each occurrence is selected independently from the definition of R ³ . Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

In cases wherein there are nitrogen atoms (e.g. , amines) on compounds of the present invention, these can be converted to N-oxides by treatment with an oxidizing agent (e.g. , MCPBA and/or hydrogen peroxides) to afford other compounds of this invention. Thus, all shown and claimed nitrogen atoms are considered to cover both the shown nitrogen and its N-oxide (N— >0) derivative. In accordance with a convention used in the art, is used in structural formulas herein to depict the bond that is the point of attachment of the moiety or substituent to the core or backbone structure.

A dash "-" that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, -CONH ₂ is attached through the carbon atom.

The term "optionally substituted" in reference to a particular moiety of the compound of Formula I (e.g. , an optionally substituted heteroaryl group) refers to a moiety having 0, 1 , 2, or more substituents. For example, "optionally substituted alkyl" encompasses both "alkyl" and "substituted alkyl" as defined below. It will be understood by those skilled in the art, with respect to any group containing one or more substituents, that such groups are not intended to introduce any substitution or substitution patterns that are sterically impractical, synthetically non-feasible and/or inherently unstable.

As used herein, the term "at least one chemical entity" is interchangeable with the term "a compound."

As used herein, the term "alkyl" or "alkylene" is intended to include both branched and straight-chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms. For example, "C _1-10 alkyl" (or alkylene), is intended to include Ci, C ₂ , C ₃ , C ₄ , C ₅ , C ₆ , C ₇ , Cg, C9, and C ₁₀ alkyl groups. Additionally, for example, "Ci-C ₆ alkyl" denotes alkyl having 1 to 6 carbon atoms. Alkyl groups can be unsubstituted or substituted so that one or more of its hydrogens are replaced by another chemical group. Example alkyl groups include, but are not limited to, methyl (Me), ethyl (Et), propyl (e.g., n-propyl and isopropyl), butyl (e.g., n-butyl, isobutyl, t-butyl), pentyl (e.g., n-pentyl, isopentyl, neopentyl), and the like.

Alkenyl" or "alkenylene" is intended to include hydrocarbon chains of either straight or branched configuration and having one or more double carbon-carbon bonds that may occur in any stable point along the chain. For example, "C ₂ _6 alkenyl" (or alkenylene), is intended to include C ₂ , C ₃ , C ₄ , C ₅ , and C ₆ alkenyl groups. Examples of alkenyl include, but are not limited to, ethenyl, 1-propenyl, 2-propenyl, 2-butenyl, 3- butenyl, 2-pentenyl, 3-pentenyl, 4-pentenyl, 2-hexenyl, 3-hexenyl, 4-hexenyl, 5-hexenyl, 2-methyl-2-propenyl, 4-methyl-3-pentenyl, and the like.

"Alkynyl" or "alkynylene" is intended to include hydrocarbon chains of either straight or branched configuration and having one or more triple carbon-carbon bonds that may occur in any stable point along the chain. For example, "C ₂ -6 alkynyl" (or alkynylene), is intended to include C ₂ , C ₃ , C ₄ , C ₅ , and C ₆ alkynyl groups; such as ethynyl, propynyl, butynyl, pentynyl, hexynyl and the like.

One skilled in the field will understand that, when the designation "C0 ₂ " is used

O

herein, this is intended to refer to the group C O

When the term "alkyl" is used together with another group, such as in "arylalkyl", this conjunction defines with more specificity at least one of the substituents that the substituted alkyl will contain. For example, "arylalkyl" refers to a substituted alkyl group as defined above where at least one of the substituents is an aryl, such as benzyl. Thus, the term aryl(Co-4)alkyl includes a substituted lower alkyl having at least one aryl substituent and also includes an aryl directly bonded to another group, i.e. , aryl(C ₀ )alkyl. The term "heteroarylalkyl" refers to a substituted alkyl group as defined above where at least one of the substituents is a heteroaryl.

When reference is made to a substituted alkenyl, alkynyl, alkylene, alkenylene, or alkynylene group, these groups are substituted with one to three substituents as defined above for substituted alkyl groups.

The term "alkoxy" refers to an oxygen atom substituted by alkyl or substituted alkyl, as defined herein. For example, the term "alkoxy" includes the group -0-Ci_6alkyl such as methoxy, ethoxy, propoxy, isopropoxy, n-butoxy, sec-butoxy, tert-butoxy, pentoxy, 2-pentyloxy, isopentoxy, neopentoxy, hexoxy, 2-hexoxy, 3-hexoxy, 3- methylpentoxy, and the like. "Lower alkoxy" refers to alkoxy groups having one to four carbons.

It should be understood that the selections for all groups, including for example, alkoxy, thioalkyl, and aminoalkyl, will be made by one skilled in the field to provide stable compounds.

The term "substituted", as used herein, means that any one or more hydrogens on the designated atom or group is replaced with a selection from the indicated group, provided that the designated atom's normal valence is not exceeded. When a substituent is oxo, or keto, (i.e., =0) then 2 hydrogens on the atom are replaced. Keto substituents are not present on aromatic moieties. Unless otherwise specified, substituents are named into the core structure. For example, it is to be understood that when (cycloalkyl)alkyl is listed as a possible substituent, the point of attachment of this substituent to the core structure is in the alkyl portion. Ring double bonds, as used herein, are double bonds that are formed between two adjacent ring atoms (e.g., C=C, C=N, or N=N).

Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds or useful synthetic intermediates. A stable compound or stable structure is meant to imply a compound that is sufficiently robust to survive isolation from a reaction mixture to a useful degree of purity, and subsequent formulation into an efficacious therapeutic agent. It is preferred that the presently recited compounds do not contain a N-halo, S(0) ₂ H, or S(0)H group.

The term "cycloalkyl" refers to cyclized alkyl groups, including mono-, bi- or poly-cyclic ring systems. C3-7 cycloalkyl is intended to include C ₃ , C ₄ , C ₅ , C ₆ , and C ₇ cycloalkyl groups. Example cycloalkyl groups include, but are not limited to,

cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, norbornyl, and the like. As used herein, "carbocycle" or "carbocyclic residue" is intended to mean any stable 3, 4, 5, 6, or 7- membered monocyclic or bicyclic or 7-, 8-, 9-, 10-, 1 1-, 12-, or 13-membered bicyclic or tricyclic ring, any of which may be saturated, partially unsaturated, unsaturated or aromatic. Examples of such carbocycles include, but are not limited to, cyclopropyl, cyclobutyl, cyclobutenyl, cyclopentyl, cyclopentenyl, cyclohexyl, cycloheptenyl, cycloheptyl, cycloheptenyl, adamantyl, cyclooctyl, cyclooctenyl, cyclooctadienyl,

(tetralin). As shown above, bridged rings are also included in the definition of carbocycle (e.g., [2.2.2]bicyclooctane). Preferred carbocycles, unless otherwise specified, are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and phenyl. When the term

"carbocycle" is used, it is intended to include "aryl". A bridged ring occurs when one or more carbon atoms link two non-adjacent carbon atoms. Preferred bridges are one or two carbon atoms. It is noted that a bridge always converts a monocyclic ring into a bicyclic ring. When a ring is bridged, the substituents recited for the ring may also be present on the bridge.

The term "aryl" refers to monocyclic or bicyclic aromatic hydrocarbon groups having 6 to 12 carbon atoms in the ring portion, such as phenyl, and naphthyl groups, each of which may be substituted. Accordingly, in compounds of formula I, the term "cycloalkyl" includes cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, bicyclooctyl, etc., as the following ring systems:

and the like, which optionally may be substituted at any available atoms of the ring(s).

Preferred cycloalkyl groups include cyclopropyl, cyclopentyl, cyclohexyl, and

The term "halo" or "halogen" refers to chloro, bromo, fluoro and iodo.

The term "haloalkyl" means a substituted alkyl having one or more halo substituents. For example, "haloalkyl" includes mono, di, and trifluoromethyl.

The term "haloalkoxy" means an alkoxy group having one or more halo substituents. For example, "haloalkoxy" includes OCF ₃ .

Thus, examples of aryl groups include:

which optionally may be substituted at any available carbon or nitrogen atom. A preferred aryl group is optionally-substituted phenyl.

The terms "heterocycle", "heterocycloalkyl", "heterocyclo", "heterocyclic", or "heterocyclyl" may be used interchangeably and refer to substituted and unsubstituted 3- to 7-membered monocyclic groups, 7- to 11-membered bicyclic groups, and 10- to 15- membered tricyclic groups, in which at least one of the rings has at least one heteroatom (O, S or N), said heteroatom containing ring preferably having 1, 2, or 3 heteroatoms selected from O, S, and N. Each ring of such a group containing a heteroatom can contain one or two oxygen or sulfur atoms and/or from one to four nitrogen atoms provided that the total number of heteroatoms in each ring is four or less, and further provided that the ring contains at least one carbon atom. The nitrogen and sulfur atoms may optionally be oxidized and the nitrogen atoms may optionally be quaternized. The fused rings completing the bicyclic and tricyclic groups may contain only carbon atoms and may be saturated, partially saturated, or fully unsaturated. The heterocyclo group may be attached at any available nitrogen or carbon atom. As used herein the terms " heterocycle", "heterocycloalkyl", "heterocyclo", "heterocyclic", and "heterocyclyl" include "heteroaryl" groups, as defined below.

Each ring of the heteroaryl group containing a heteroatom can contain one or two oxygen or sulfur atoms and/or from one to four nitrogen atoms provided that the total number of heteroatoms in each ring is four or less and each ring has at least one carbon atom. The fused rings completing the bicyclic and tricyclic groups may contain only carbon atoms and may be saturated, partially saturated, or unsaturated. The nitrogen and sulfur atoms may optionally be oxidized and the nitrogen atoms may optionally be quaternized. Heteroaryl groups which are bicyclic or tricyclic must include at least one fully aromatic ring but the other fused ring or rings may be aromatic or non- aromatic. The heteroaryl group may be attached at any available nitrogen or carbon atom of any ring.

Unless otherwise indicated, when reference is made to a specifically-named aryl (e.g., phenyl), cycloalkyl (e.g., cyclohexyl), heterocyclo (e.g., pyrrolidinyl, piperidinyl, and morpholinyl) or heteroaryl (e.g., tetrazolyl, imidazolyl, pyrazolyl, triazolyl, thiazolyl, and furyl) the reference is intended to include rings having 0 to 3, preferably 0 to 2, substituents selected from those recited above for the aryl, cycloalkyl, heterocyclo and/or heteroaryl groups, as appropriate.

The terms "carbocycle, carbocyclyl or "carbocyclic" refers to a saturated or unsaturated monocyclic or bicyclic ring in which all atoms of all rings are carbon. Thus, the term includes cycloalkyl and aryl rings. Monocyclic carbocycles have 3 to 6 ring atoms, still more typically 5 or 6 ring atoms. Bicyclic carbocycles have 7 to 12 ring atoms, e.g., arranged as a bicyclo [4,5], [5,5], [5,6] or [6,6] system, or 9 or 10 ring atoms arranged as a bicyclo [5,6] or [6,6] system.

Throughout the specification, groups and substituents thereof may be chosen by one skilled in the field to provide stable moieties and compounds and compounds useful as pharmaceutically-acceptable compounds and/or intermediate compounds useful in making pharmaceutically-acceptable compounds.

The compounds of formula I may exist in a free form (with no ionization) or can form salts which are also within the scope of this invention. Unless otherwise indicated, reference to an inventive compound is understood to include reference to the free form and to salts thereof. The term "salt(s)" denotes acidic and/or basic salts formed with inorganic and/or organic acids and bases. In addition, the term "salt(s) may include zwitterions (inner salts), e.g., when a compound of formula I, contains both a basic moiety, such as an amine or a pyridine or imidazole ring, and an acidic moiety, such as a carboxylic acid. Pharmaceutically acceptable {i.e., non-toxic, physiologically acceptable) salts are preferred, such as, for example, acceptable metal and amine salts in which the cation does not contribute significantly to the toxicity or biological activity of the salt. However, other salts may be useful, e.g. , in isolation or purification steps which may be employed during preparation, and thus, are contemplated within the scope of the invention. Salts of the compounds of the formula I may be formed, for example, by reacting a compound of the formula I with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization.

Preferred salts include monohydrochloride, hydrogensulfate, methanesulfonate, phosphate or nitrate salts.

The phrase "pharmaceutically acceptable" is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. As used herein, "pharmaceutically acceptable salts" refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines; and alkali or organic salts of acidic groups such as carboxylic acids. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, and nitric; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic,

methanesulfonic, ethane disulfonic, oxalic, and isethionic, and the like.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington 's Pharmaceutical Sciences, 18th Edition, Mack

Publishing Company, Easton, PA (1990), the disclosure of which is hereby incorporated by reference.

All stereoisomers of the compounds of the instant invention are contemplated, either in admixture or in pure or substantially pure form. Stereoisomers may include compounds which are optical isomers through possession of one or more chiral atoms, as well as compounds which are optical isomers by virtue of limited rotation about one or more bonds (atropisomers). The definition of compounds according to the invention embraces all the possible stereoisomers and their mixtures. It very particularly embraces the racemic forms and the isolated optical isomers having the specified activity. The racemic forms can be resolved by physical methods, such as, for example, fractional crystallization, separation or crystallization of diastereomeric derivatives or separation by chiral column chromatography. The individual optical isomers can be obtained from the racemates from the conventional methods, such as, for example, salt formation with an optically active acid followed by crystallization.

The present invention is intended to include all isotopes of atoms occurring in the present compounds. Isotopes include those atoms having the same atomic number but different mass numbers. By way of general example and without limitation, isotopes of hydrogen include deuterium and tritium. Isotopes of carbon include ¹³ C and ¹⁴ C.

Isotopically-labeled compounds of the invention can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described herein, using an appropriate isotopically-labeled reagent in place of the non-labeled reagent otherwise employed.

Prodrugs and solvates of the inventive compounds are also contemplated. The term "prodrug" denotes a compound which, upon administration to a subject, undergoes chemical conversion by metabolic or chemical processes to yield a compound of the formula I, and/or a salt and/or solvate thereof. Any compound that will be converted in vivo to provide the bioactive agent {i.e. , the compound for formula I) is a prodrug within the scope and spirit of the invention. For example, compounds containing a carboxy group can form physiologically hydrolyzable esters which serve as prodrugs by being hydro lyzed in the body to yield formula I compounds per se. Such prodrugs are preferably administered orally since hydrolysis in many instances occurs principally under the influence of the digestive enzymes. Parenteral administration may be used where the ester per se is active, or in those instances where hydrolysis occurs in the blood. Examples of physiologically hydrolyzable esters of compounds of formula I include Ci_ ₆ alkylbenzyl, 4-methoxybenzyl, indanyl, phthalyl, methoxymethyl, Ci_ ₆ alkanoyloxy-Ci_ ₆ alkyl, e.g., acetoxymethyl, pivaloyloxymethyl or propionyloxymethyl, Ci_ ₆ alkoxycarbonyloxy-Ci_ ₆ alkyl, e.g., methoxycarbonyl-oxymethyl or

ethoxycarbonyloxymethyl, glycyloxymethyl, phenylglycyloxymethyl, (5-methyl-2-oxo- l ,3-dioxolen-4-yl)-methyl and other well known physiologically hydrolyzable esters used, for example, in the penicillin and cephalosporin arts. Such esters may be prepared by conventional techniques known in the art.

Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see: a) Bundgaard, H., ed., Design of Prodrugs, Elsevier (1985), and Widder, K. et al, eds., Methods in Enzymology, 112:309-396, Academic Press (1985);

each of which is incorporated herein by reference.

Compounds of the formula I and salts thereof may exist in their tautomeric form, in which hydrogen atoms are transposed to other parts of the molecules and the chemical bonds between the atoms of the molecules are consequently rearranged. It should be understood that the all tautomeric forms, insofar as they may exist, are included within the invention. Additionally, inventive compounds may have trans and cis isomers.

It should further be understood that solvates (e.g., hydrates) of the compounds of Formula I are also with the scope of the present invention. Methods of solvation are generally known in the art.

Another aspect of the invention is a pharmaceutical composition including a compound, stereoisomeric form, pharmaceutical salt, solvate or hydrate as described herein. The pharmaceutical compositions described herein generally comprise a combination of a compound described herein and a pharmaceutically acceptable carrier, diluent, or excipient. Such compositions are substantially free of non-pharmaceutically acceptable components, i.e., contain amounts of non-pharmaceutically acceptable components lower than permitted by U.S. regulatory requirements at the time of filing this application. In some embodiments of this aspect, if the compound is dissolved or suspended in water, the composition further optionally comprises an additional pharmaceutically acceptable carrier, diluent, or excipient. In other embodiments, the pharmaceutical compositions described herein are solid pharmaceutical compositions (e.g., tablet, capsules, etc.).

These compositions can be prepared in a manner well known in the

pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is desired and upon the area to be treated.

Administration may be topical (including ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal, intranasal, epidermal and transdermal), ocular, oral or parenteral. Methods for ocular delivery can include topical administration (eye drops), subconjunctival, periocular or intravitreal injection or introduction by balloon catheter or ophthalmic inserts surgically placed in the conjunctival sac. Parenteral administration includes intravenous, intraarterial,

subcutaneous, intraperitoneal or intramuscular injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or may be, for example, by a continuous perfusion pump.

Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable.

Also, pharmaceutical compositions can contain, as the active ingredient, one or more of the compounds described herein above in combination with one or more pharmaceutically acceptable carriers. In making the compositions described herein, the active ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders.

In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh.

Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions described herein can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the subject by employing procedures known in the art.

The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual subject, the severity of the subject's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound described herein. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.

This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, 0.1 to about 500 mg of the active ingredient of a compound described herein.

The tablets or pills can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate. The liquid forms in which the compounds and compositions can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect.

Compositions in can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face masks tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.

The amount of compound or composition administered to a subject will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the subject, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a subject already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the subject, and the like.

The compositions administered to a subject can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts. The therapeutic dosage of the compounds can vary according to, for example, the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the subject, and the judgment of the prescribing physician. The proportion or concentration of a compound described herein in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds described herein can be provided in an aqueous

physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular subject, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

The compounds of the present invention are useful to prevent, diagnose, and treat various medical disorders in humans or animals. The compounds are used to inhibit or reduce one or more activities associated with RORy receptors, relative to RORy receptors in the absence of the same compounds. Thus, in one aspect of the invention, a method for treating a disease or disorder selected from an autoimmune disease or disorder, asthma, an allergic disease or disorder, a metabolic disease or disorder, and cancer in a subject comprises administering to the subject a therapeutically effective amount of compound according to formula (I), stereoisomeric form, N-oxide, pharmaceutically acceptable salt, solvate, hydrate or pharmaceutical composition as described herein.

METHODS OF PREPARATION The compounds of the present invention may be synthesized by many methods available to those skilled in the art of organic chemistry. General synthetic schemes for preparing compounds of the present invention are described below. These schemes are illustrative and are not meant to limit the possible techniques one skilled in the art may use to prepare the compounds disclosed herein. Different methods to prepare the compounds of the present invention will be evident to those skilled in the art.

Additionally, the various steps in the synthesis may be performed in an alternate sequence in order to give the desired compound or compounds. Examples of compounds of the present invention prepared by methods described in the general schemes are given in the preparations and examples section set out hereinafter. Preparation of homochiral examples may be carried out by techniques known to one skilled in the art. For example, homochiral compounds may be prepared by separation of racemic products by chiral phase preparative HPLC. Alternatively, the example compounds may be prepared by methods known to give enantiomerically enriched products.

Scheme 1 illustrates a general synthesis of piperidine 10. Appropriately functionalized benzyl halide 1 can be reacted with functionalized thiophenol 2 using a base such as potassium carbonate or sodium hydroxide in a solvent such as

tetrahydrofuran, ethanol or Ν,Ν-dimethylformamide to provide sulfide intermediate 3. Oxidation of 3 to sulfone 4 can be accomplished with mCPBA or other oxidant such as oxone and sodium tungstate. Alternatively, sulfone 4 can be synthesized in one step by treating 1 with sodium benzenesulfmate 5 in a solvent such as N,N-dimethylformamide. Upon treatment with n-butyllithium, the resulting anion derivative of 4 can be reacted with Eschenmoser's salt (dimethylmethylideneammonium iodide) to yield amine derivative 6, which can be converted to vinyl sulfone 7 after heating in acetic anhydride and toluene. Vinyl sulfone 7 can also be synthesized directly from 4 by heating with Ν,Ν,Ν',Ν'-tetramethylmethylenediamine and acetic anhydride in N,N- dimethylformamide. Michael addition of 3-aminopropanol to vinyl sulfone 7 can provide alcohol 8. After reaction with methanesulfonyl chloride and a base such as triethylamine, the resulting mesylate 9 can be converted to piperidine 10 using a base such as potassium t-butoxide or sodium hydride. The two enantiomers of 10 can be resolved with chiral HPLC. Racemic or enantiomerically pure form of 10 can be further functionalized following conditions described in Scheme 3 below. Scheme 1

Scheme 2 illustrates a synthesis of a series of compounds 17 and 18 where R ¹ is

1,1,1, 3,3, 3-hexafluoro-2-hydroxypropan-2-yl group. Commercially available 1,1,1,3,3,3- hexafluoro-2-(p-tolyl)propan-2-ol (11) can be selectively brominated with N- bromosuccinimide in refluxing carbon tetrachloride using AIBN as radical initiator to yield bromide 12. Reaction of 12 with sodium benzenesulfmate 5 in a solvent such as Ν,Ν-dimethylformamide could lead to sulfone product 13. The hydroxyl group in 13 can be protected as a benzyl ether using conditions such as benzyl bromide and potassium carbonate in Ν,Ν-dimethylformamide. Treatment of the resulting benzyl ether 14 with di- halide 15 in a solvent such as Ν,Ν-dimethylformamide under basic conditions (such as sodium hydride) can provide tetrahydropyran 16a and piperidine 16b. Palladium(II) hydroxide-catalyzed hydrogeno lysis of 16 could cleave the benzyl ether to provide the two alcohol products 17a and 17b. The Boc protecting group in 17b can be removed with trifluoroacetic acid or hydrogen chloride to yield piperidine 18, which can be further functionalized according to conditions outlined in Scheme 3.

The free cyclic amines of compound 19 (for example, 3-piperidinyl analogue 10 and 4-piperidinyl analogue 18) can be functionalized using various well known transformations to give 20 (Scheme 3). Examples of these transformations include, but are not limited to, alkylation reaction with alkyl halide and a base such as Hunig's base, reductive alkylation with aldehyde/ketone and a reducing reagent such as sodium triacetoxyborohydride, coupling reaction with carboxylic acid using an activating agent such as BOP or HOBt/EDC, and other acylation reactions using acid chloride, anhydride, chloroformate, isocyanate, and sulfonyl chloride. Optionally, enantiomers of 20 can be separated using chiral HPLC if racemic 19 is used in the reaction.

Scheme 3

Compound 21, prepared according to Schemes 1-3, can also be useful

intermediate for further derivatization (Scheme 4). For example, it can be alkylated with R ^la -halide (chloride, bromide or iodide) under basic conditions such as potassium carbonate or sodium hydride to give 22. Alternatively, compound 22 can be synthesized from 21 and alcohol R ^la -OH using Mitsunobu conditions involving an azodicarboxylate such as diethyl azodicarboxylate (DEAD) and a phosphine ligand such as

triphenylphosphine or tributylphosphine. The hydroxyl group in 21 can also be replaced with a fluoro group using (diethylamino)sulfur trifluoride (DAST) to give

perfluoroisopropyl analogue 23. In addition, the OH group in 21 can be arylated with diphenyliodonium iodide 24 using a base such as potassium methoxide or sodium hydride to give phenyl ether 25. All of the transformation in Scheme 4 can also be carried out on suitably protected cyclic amine 21 (R ² = protecting group such as Bn, Boc or Cbz).

Subsequent deprotection and chemical manipulation to install R ² group would complete the synthesis.

Scheme 4

Iodide 26, prepared from the sequence outlined in Scheme 1, can be a useful intermediate for further diversification to prepare 28, 30 and 31 (Scheme 5). It can be reacted with aryl/heteroaryl boronic acid (or ester) 27 under well-known Suzuki coupling conditions using a catalyst such as palladium tetrakis(triphenylphosphine) or Pd(dppf)Cl ₂ to give compound 28. Compound 28 can also be obtained under Stille coupling conditions using aryl/heteroaryltin in place of the boronic acid 27. Iodide 26 can also be treated with tert-butyllithium or ethylmagensium bromide to produce the corresponding aryllithium or arylmagnesium species, which can react with ketone 29 to produce alcohol 30. Compound 30 can in turn be converted to ether 31 using previously described conditions. All of the transformations in Scheme 5 can also be performed on suitably protected cyclic amine 26 (R ² = protecting group such as Bn, Boc or Cbz). Subsequent deprotection and chemical manipulation to install R ² group would complete the synthesis.

Frequently chemists skilled in the art of synthesis may devise alternative preparations which may be desirable based on one or more considerations such as shorter reaction time, less expensive starting materials, ease of operation, amenable to catalysis, avoidance of toxic reagents, accessibility of specialized instrumentation, and decreased number of linear steps, etc. The intent of describing alternative preparations is to further enable the preparation of the examples of this invention. In some instances some functional groups in the outlined examples and claims may be replaced by well known bioisosteric replacements known in the art, for example, replacement of a carboxylic acid group with a tetrazole or a phosphate moiety.

General RORy SPA binding assay

The binding of potential ligands to RORy is measured by competition with [ ³ H] 25 -hydroxy cholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORy (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15ug/well RORy (A262-S507) is incubated with test compound at varying concentrations in 3 -fold serial dilution, with final concentrations ranging from 16.6 μΜ to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen # 14190- 144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat# G5516). ΙΟηΜ of [ ³ H] 25-hydroxycholesterol is then added, and the reaction is incubated for lOmin. lOmg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat # RPNQ0095) are added, and the mixture is incubated for 60min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC ₅₀ values were determined. The IC ₅₀ value is defined as the concentration of test compound needed to reduce [ ³ H] 25-hydroxycholesterol specific binding by 50%> and is calculated using the four parameter logistic equation to fit the normalized data. IC ₅₀ values of the compounds of the invention in the RORy binding assay are provided below.
