PYRROLO CARBOXAMIDES AS MODULATORS OF ORPHAN NUCLEAR RECEPTOR RAR-RELATED ORPHAN RECEPTOR-GAMMA (RORy, NR1F3) ACTIVITY AND FOR THE TREATMENT OF CHRONIC INFLAMMATORY AND AUTOIMMUNE DISEASES

The invention provides pyrrolo carboxamide compounds as modulators for the orphan nuclear receptor RORγ and methods for treating RORγ mediated chronic inflammatory and autoimmune diseases by administrating these novel RORγ modulators to a human or a mammal in need thereof.

The retinoid-receptor related orphan receptors consist of three family members, namely RORα (Beckerandre et al., Biochem. Biophys. Res. Commun. 1993, 194:1371), RORβ (Andre et al., Gene 1998, 516:277) and RORγ (He et al., Immunity 1998, 9:797) and constitute the NR1F (ROR/RZR) subgroup of the nuclear receptor superfamily (Mangelsdorf et al., Cell 1995, 83:835).

The nuclear receptor superfamily shares common modular structural domains consisting of a hypervariable N-terminal domain, a conserved DNA binding domain (DBD), a hinge region and a conserved ligand-binding domain (LBD). The DBD targets the receptor to specific DNA sequences (nuclear hormone response elements or NREs) and the LBD functions in the recognition of endogenous or exogenous chemical ligands. A constitutive transcriptional activation domain is found at the N-terminus (AF1) and a ligand regulated transcriptional activation domain is embedded within the C-terminal LBD of typical NRs. The nuclear receptors can exist in a transcriptional activating or repressing state when bound to their target NREs. The basic mechanism of gene activation involves ligand dependent exchange of co-regulatory proteins, namely co-activators and co-repressors (McKenna et al., Endocrine Rev. 1999, 20:321). A NR in the repressing state is bound to its DNA recognition element and is associated with co-repressor proteins that recruit histone-deacetylases (HDACs). In the presence of an agonist, co-repressors are exchanged for coactivators that recruit transcription factors, which contribute to assembling of a chromatin-remodelling complex, which relieves transcriptional repression and stimulates transcriptional initiation via histone acetylation. The AF-2 domain of the LBD acts as a ligand dependant molecular switch presenting interaction surfaces for co-repressor or co-activator proteins and providing with a conserved mechanism for gene activation or repression that is shared by the members of the nuclear receptor superfamily.

The members of the NR1F family of nuclear receptors (such as RORγ) have been considered to be constitutively active transcription factors in the absence of known ligands, which is similar to the estrogen-related receptor alpha (Vanacker et al., Mol. Endocrinol. 1999, 13:764). Most recently, 7-oxygenated oxysterols were identified to be high affinity ligands for RORα and RORγ (Wang et al., J. Biol. Chem. 2010, 285:5013). 7-Hydroxycholesterol is a key metabolite during the conversion of cholesterol into bile acids, but to date it is not clear whether it is a true endogenous ligand for the RORs. In any case it can be expected that inverse agonists of RORγ should reduce the transcriptional activity of RORγ and influence the biological pathways controlled by RORγ.

The RORs are expressed as isoforms arising from differential splicing or alternative transcriptional start sites. So far, isoforms have been described that differ only in their N-terminal domain (NB-domain). In humans, four different RORα isoforms have been identified (RORα 1-4) while only two isoforms are known for both RORβ (1 and 2) and RORγ (1 and 2) (Andre et al., Gene 1998, 216:277; Villey et al., Eur. J. Immunol. 1999, 29:4072). RORγ is used herein as a term describing both, RORγ1 and/or RORγ2 (also called RORγt).

The ROR isoforms show different tissue expression patterns and regulate different target genes and physiological pathways. For example, the RORγt is highly restricted to CD4⁺CD8⁺ thymocytes and to interleukin-17 (IL-17) producing T cells while other tissues express RORγ1 (Eberl et al., Science 2004, 305:248, Zhou and Littmann, Curr. Opin. Immunol. 2009, 21:146).

RORs exhibit a structural architecture that is typical of nuclear receptors. RORs contain four major functional domains: an amino-terminal (A/B) domain, a DNA-binding domain, a hinge domain and a ligand-binding domain (Evans et al., Science 1988, 240:889). The DBD consists of two highly conserved zinc finger motifs involved in the recognition of ROR response elements (ROREs) which consist of the consensus motif AGGTCA preceded by an AT-rich sequence (Andre et al., Gene 1998, 216:277) which is similar to that of the nuclear receptors Rev-ErbAα and Rev-Erbβ (NR1D1 and D2, respectively) (Giguere et al., Genomics 1995, 28:596). These recognition elements do also show high similarity to those identified for the estrogen related receptors and in particular ERRα (ERRs, NR3B1, -2, -3) (Vanacker et al., Mol. Endocrinol. 1999, 13:764), steroidogenic factor 1 (SF-1, NR5A) and NGFI-B (NR4A1, -2, -3) (Wilson et al., Mol. Cell. Biol. 1993, 13:5794).

RORα is highly expressed in different brain regions and most highly in cerebellum and thalamus. RORα knock-out mice show ataxia with strong cerebellar atrophy, highly similar to the symptoms displayed in the so-called staggerer mutant mouse (RORα^sg/sg). This mouse carries mutations in RORα that results in a truncated RORα which does not contain a LBD (Hamilton et al., Nature 1996, 379:736).

Analysis of RORα^sg/sgstaggerer-mice have revealed a strong impact on lipid metabolism beyond the CNS defects, namely significant decreases in serum and liver triglyceride, reduced serum HDL cholesterol levels and reduced adiposity. SREBP1c and the cholesterol transporters ABCA1 and ABCG1 are reduced in livers of staggerer mice and CHIP analysis suggest that RORα is directly recruited to and regulates the SREBP1c promoter. In addition, PGC1α, PGC1β, lipin1 and β2-adrenergic receptor were found to be increased in tissues such as liver or white and brown adipose tissue, which may help to explain the observed resistance to diet-induced obesity in staggerer mice (Lau et al., J. Biol. Chem. 2008, 283:18411).

RORβ expression is mainly restricted to the brain and most abundantly found in the retina. RORβ knock-out mice display a duck-like gait and retinal degeneration which leads to blindness (Andre et al., EMBO J. 1998, 17:3867). The molecular mechanisms behind this retinal degeneration are still poorly understood.

RORγ (particularly RORγt) null-mutant mice lack lymph nodes and Peyer's patches (Eberl and Littmann, Immunol. Rev. 2003, 195:81) and lymphatic tissue inducer (LTi) cells are completely absent from spleen mesentery and intestine. In addition, the size of the thymus and the number of thymocytes is greatly reduced in RORγ null mice (Sun et al., Science 2000, 288:2369) due to a reduction in double-positive CD4⁺CD8⁺ and single positive CD4⁻CD8⁺ or CD4⁺CD8⁻ cells suggesting a very important role of RORγt in thymocyte development.

Thymocyte development follows a complex program involving coordinated cycles of proliferation, differentiation, cell death and gene recombination in cell populations dedicated by their microenvironment. Pluripotent lymphocyte progenitors migrating from fetal liver or adult bone marrow to the thymus are being committed to the T-cell lineage. They develop through a series of steps from CD4⁻CD8⁻ double negative cells to CD4⁺CD8⁺ cells and those with low affinity towards self-MHC peptides are eliminated by negative selection. These develop further into CD4⁻CD8⁺ (killer) or CD4⁺CD8⁻ (helper) T-cell lineages. RORγt is not expressed in double negative and little expressed in immature single negative thymocytes (He et al., J. Immunol. 2000, 164:5668), while highly upregulated in double-positive thymocytes and downregulated during differentiation in single-positive thymocytes. RORγ deficiency results in increased apoptosis in CD4⁺CD8⁺ cells and the number of peripheral blood thymocytes is decreased by 6-fold (10-fold CD4⁺ and 3-fold CD8⁺ thymocytes).

Recent experiments in a model of ovalbumin (OVA)-induced inflammation in mice, as a model for allergic airway disease, demonstrated a severe impairment of the development of the allergic phenotype in the RORγ KO mice with decreased numbers of CD4⁺ cells and lower Th2 cytokine/chemokine protein and mRNA expression in the lungs after challenge with OVA (Tilley et al., J. Immunol. 2007, 178:3208). IFN-γ and IL-10 production were increased in splenocytes following re-stimulation with the OVA antigen compared to wt splenocytes suggesting a shift towards a Th1 type immune response on cost of a reduction of Th2 type response. This suggests that down-modulation of RORγ transcriptional activity with a ligand could result in a similar shift of the immune response towards a Th1 type response, which could be beneficial in the treatment of certain pulmonary diseases like asthma, chronic obstructive pulmonary disease (COPD) or allergic inflammatory conditions.

T-helper cells were previously considered to consist of Th1 and Th2 cells. However, a new class of Th cells, the Th17 cells, which produce IL-17, were also identified as a unique class of T-cells that are considered to be pro-inflammatory. They are recognized as key players in autoimmune and inflammatory diseases since IL-17 expression has been associated with many inflammatory diseases such as rheumatoid arthritis, systemic lupus erythematosus (SLE) and allograft rejection. (Tesmer et al., Immunol. Rev. 2008, 223:87).

RORγt is exclusively expressed in cells of the immune system and has been identified as a master regulator of Th17 cell differentiation. Expression of RORγt is induced by TGF-beta or IL-6 and overexpression of RORγt results in increased Th17 cell lineage and IL-17 expression. RORγt KO mice show very little Th17 cells in the intestinal lamina propria and demonstrate an attenuated response to challenges that usually lead to autoimmune disease (Ivanov et al., Cell 2006, 126:1121).

Inhibition of IL-17 production via inhibition of Th17 cell development may also be advantageous in atopic dermatitis and psoriasis where IL-17 is deeply involved. Interestingly, recent evidence was presented that IL-10 suppresses the expression of IL-17 secreted by both, macrophages and T-cells. In addition, the expression of the Th17 transcription factor RORγt was suppressed (Gu et al., Eur. J. Immunol. 2008, 38:1807). Moreover, IL-10 deficient mice provide a good model for inflammatory bowel disease (IBD) where a shift towards a Th1 type inflammatory response is frequently observed. Oral IL-10 delivery poses a potential treatment option for IBD.

The proinflammatory actions of IL-17 producing Th17 cells are counteracted by another T-helper cell type, so-called regulatory T-cells or Tregs. Naïve T-cells are differentiated into Tregs upon stimulation by TGFβ. This results in upregulation of the transcriptional modulator FoxP3 resulting in CD4⁺FoxP3⁺ Tregs. In case the naïve T-cells are co-stimulated by IL-6, FoxP3 expression is suppressed and RORγt expression is induced. These CD4⁺FoxP3⁻RORγt⁺ T-helper cells then differentiate into IL-17 producing Th17 cells. (reviewed in Awasthi and Kuchroo, Int. Immunol. 2009, 21:489 and Zhou and Littmann, Curr. Opin. Immunol. 2009, 21:146). Several lines of evidence suggest that these Th17 cells are responsible for the etiology of a whole range of autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, ankylosing spondylitis, psoriasis, Crohn's disease and other types of inflammatory bowel disease, lupus erythematosus and asthma. The severity of disease seems to correlate with the presence of IL-17⁺ Th17 cells and it is believed that interception of RORγt by a small molecule inverse agonist or antagonist should result in a reduction of these IL-17⁺ Th17 cells ultimately leading to alleviation of disease symptoms and outcome (Crome et al., Clin. Exp. Immunol. 2010, 159:109).

Ligands for the RORs:

It was reported that cholesterol and its sulfated derivatives might function as RORα ligands and in particular cholesterol-sulfate could restore transcriptional activity of RORα in cholesterol-depleted cells (Kallen et al., Structure 2002, 10:1697). Previously, melatonin (Missbach et al., J. Biol. Chem. 1998, 271:13515) and thiazolidinediones were suggested to bind to RORα (Wiesenberg et al., Nucleic Acid Res. 1995, 23:327). However, none of these have been shown to be functional ligands of RORα or of any other of the RORs. Certain retinoids including all-trans retinoid acid have been demonstrated to bind to RORβ and function as partial antagonists for RORβ but not RORα (Stehlin-Gaon et al., Nat. Struct Biol. 2003, 10:820).

Recently, 7-oxygenated sterols such as 7-hydroxy-cholesterol and 7-keto-cholesterol were identified as highly potent modulators of RORγ activity (Wang et al., J. Biol. Chem. 2010, 285:5013) in in vitro assays. The same group of investigators also found that a known LXR agonist, T0901317 ([N-(2,2,2-trifluoroethyl)-N-[4-[2,2,2-trifluoro-1-hydroxy-1-(trifluoro-methyl)ethyl]phenyl]-benzenesulfonamide]) acts as a RORγ inverse agonist at submicromolar potency (Kumar et al., Mol. Pharmacol. 2010, 77:228). In neither case, however, in vivo data were obtained that demonstrate a beneficial impact of these RORγ modulating compounds. In case of the 7-oxysterols their endogenous presence as metabolites naturally produced by the body itself as well as their rapid turnover and their biological activities on many cellular proteins prevent a meaningful animal study that allows drawing conclusions on the role of RORγ. In case of the T0901317 its polypharmacodynamic properties, acting on at least six different nuclear receptors (LXRα/β, FXR, PXR, RORα/γ) prevents its usefulness as a drug candidate for the development in an autoimmune disease application (Houck et al., Mol. Genet. Metab. 2004, 83:184; Xue et al., Bioorg. Med. Chem. 2007, 15:2156).

A 5- to 10-membered mono- or bicyclic heteroaryl system containing up to 4 heteroatoms means a monocyclic heteroaromatic ring such as pyrrolyl, imidazolyl, furanyl, thiophenyl, pyridinyl, pyrimidinyl, pyrazinyl, pyrazolyl, oxazolyl, isoxazolyl, triazolyl, oxadiazolyl and thiadiazolyl. It further means a bicyclic ring system wherein the heteroatom(s) may be present in one or both rings including the bridgehead atoms. Examples thereof include quinolinyl, isoquinolinyl, quinoxalinyl, benzimidazolyl, benzisoxazolyl, benzodioxanyl, benzofuranyl, benzoxazolyl, indolyl, indolizinyl and pyrazolo[1,5-a]pyrimidinyl.

A 6- to 10-membered mono- or bicyclic aryl system means an aromatic carbon cycle such as phenyl or naphthalenyl.

The term “N-oxide” denotes compounds, there the nitrogen in the heteroaromatic system (preferably pyridinyl) is oxidized. Such compounds can be obtained in a known manner by reacting a compound of the present invention (such as in a pyridinyl group) with H₂O₂or a peracid in an inert solvent.

Halogen is selected from fluorine, chlorine, bromine and iodine. The preferred halogen is fluorine.

Furthermore, the compounds of the present invention are partly subject to tautomerism. For example, if a heteroaromatic group containing a nitrogen atom in the ring is substituted with a hydroxy group on the carbon atom adjacent to the nitrogen atom, the following tautomerism can appear:

When a substitution of a residue with cycloalkyl or heterocycloalkyl is described, it is understood that the substitution can be connected straight and, when the connecting carbon atom is sp³-hybridized, in addition spirocyclic. For example, when cyclohexan is substituted with the heterocycloalkyl group oxetan-3-yl, the following structures are possible:

It will be appreciated by the skilled person that when lists of alternative substituents include members which, because of their valency requirements or other reasons, cannot be used to substitute a particular group, the list is intended to be read with the knowledge of the skilled person to include only those members of the list which are suitable for substituting the particular group.

The compounds used in the present invention can be in the form of a pharmaceutically acceptable salt or a solvate. The term “pharmaceutically acceptable salts” refers to salts prepared from pharmaceutically acceptable non-toxic bases or acids, including inorganic bases or acids and organic bases or acids. In case the compounds of the present invention contain one or more acidic or basic groups, the invention also comprises their corresponding pharmaceutically or toxicologically acceptable salts, in particular their pharmaceutically utilizable salts. Thus, the compounds of the present invention which contain acidic groups can be used according to the invention, for example, as alkali metal salts, alkaline earth metal salts or ammonium salts. More precise examples of such salts include sodium salts, potassium salts, calcium salts, magnesium salts or salts with ammonia or organic amines such as, for example, ethylamine, ethanolamine, triethanolamine or amino acids. The compounds of the present invention which contain one or more basic groups, i.e. groups which can be protonated, can be used according to the invention in the form of their addition salts with inorganic or organic acids. Examples of suitable acids include hydrogen chloride, hydrogen bromide, phosphoric acid, sulfuric acid, nitric acid, methanesulfonic acid, p-toluenesulfonic acid, naphthalenedisulfonic acids, oxalic acid, acetic acid, tartaric acid, lactic acid, salicylic acid, benzoic acid, formic acid, propionic acid, pivalic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, malic acid, sulfaminic acid, phenylpropionic acid, gluconic acid, ascorbic acid, isonicotinic acid, citric acid, adipic acid and other acids known to the person skilled in the art. If the compounds of the present invention simultaneously contain acidic and basic groups in the molecule, the invention also includes, in addition to the salt forms mentioned, inner salts or betaines (zwitterions). The respective salts can be obtained by customary methods which are known to the person skilled in the art like, for example, by contacting these with an organic or inorganic acid or base in a solvent or dispersant, or by anion exchange or cation exchange with other salts. The present invention also includes all salts of the compounds of the present invention which, owing to low physiological compatibility, are not directly suitable for use in pharmaceuticals but which can be used, for example, as intermediates for chemical reactions or for the preparation of pharmaceutically acceptable salts.

In practical use, the compounds used in the present invention can be combined as the active ingredient in intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g., oral or parenteral (including intravenous). In preparing the compositions for oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like in the case of oral liquid preparations, such as, for example, suspensions, elixirs and solutions; or carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents and the like in the case of oral solid preparations such as, for example, powders, hard and soft capsules and tablets, with the solid oral preparations being preferred over the liquid preparations.

Because of their ease of administration, tablets and capsules represent the most advantageous oral dosage unit form in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be coated by standard aqueous or non-aqueous techniques. Such compositions and preparations should contain at least 0.1 percent of active compound. The percentage of active compound in these compositions may, of course, be varied and may conveniently be between about 2 percent to about 60 percent of the weight of the unit. The amount of active compound in such therapeutically useful compositions is such that an effective dosage will be obtained. The active compounds can also be administered intranasally as, for example, liquid drops or spray.

The tablets, pills, capsules and the like may also contain a binder such as gum tragacanth, acacia, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid; a lubricant such as magnesium stearate; and a sweetening agent such as sucrose, lactose or saccharin. When a dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier such as a fatty oil.

Various other materials may be present as coatings or to modify the physical form of the dosage unit. For instance, tablets may be coated with shellac, sugar or both. A syrup or elixir may contain, in addition to the active ingredient, sucrose as a sweetening agent, methyl and propylparabens as preservatives, a dye and a flavoring such as cherry or orange flavor.

The compounds used in the present invention may also be administered parenterally. Solutions or suspensions of these active compounds can be prepared in water suitably mixed with a surfactant such as hydroxy-propylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils.

Any suitable route of administration may be employed for providing a mammal, especially a human, with an effective dose of a compound of the present invention. For example, oral, rectal, topical, parenteral (including intravenous), ocular, pulmonary, nasal and the like may be employed. Dosage forms include tablets, troches, dispersions, suspensions, solutions, capsules, creams, ointments, aerosols and the like. Preferably compounds of the present invention are administered orally.

The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration, the condition being treated and the severity of the condition being treated. Such dosage may be ascertained readily by a person skilled in the art.

When treating or preventing RORγ-mediated conditions for which compounds of Formula (1) are indicated, generally satisfactory results are obtained when the compounds are administered at a daily dosage of from about 0.1 milligram to about 100 milligram per kilogram of mammal body weight, preferably given as a single daily dose or in divided doses two to six times a day, or in sustained release form. For most large mammals, the total daily dosage is from about 1.0 milligram to about 1000 milligrams, preferably from about 1 milligram to about 50 milligrams. In the case of a 70 kg adult human, the total daily dose will generally be from about 7 milligrams to about 350 milligrams. This dosage regimen may be adjusted to provide the optimal therapeutic response.

The present invention describes modulators, in the following also referred to as ligands, which bind to the RORγ receptor. Surprisingly, it has been found that compounds of Formula (1) act as modulators of the RORγ receptor.

The RORγ receptor is considered to be involved in thymocyte development, thus the modulators described herein may be useful in the treatment of inflammatory skin diseases such as atopic eczema and psoriasis. It is further suggested that down-modulation of RORγ transcriptional activity with a ligand could result in a shift of the immune response towards a Th2 type response which could be beneficial in the treatment of certain allergic inflammatory conditions such as rheumatoid arthritis, systemic lupus erythomatosis, inflammatory bowel disease (Crohn's Disease) and multiple sclerosis (Tesmer et. al., Immunol. Rev. 2008, 223:97).

The compounds of Formula (1) show antagonistic activity, with respect to the dose dependent modulation of the constitutive interaction of the RORγ ligand binding domain with peptides derived from the co-activators such as SRC-1, TRAP 220 or TIF-2.

It has been surprisingly found that the interaction between RORγ ligand binding domain and the peptides can be determined by a homogenous FRET based ligand-sensing assays. Even more surprising was the identification of compounds of Formula (1) as ligands for RORγ.

The identification of high affinity ligands for RORγ with agonistic and antagonistic properties is the basis to enable experts knowledgeable in the field to establish assays for the identification of novel agonistic and antagonistic RORγ ligands from libraries of small molecules. The identification of ligands which bind to and modulate the activity of RORγ1 and RORγt is the first mandatory step to develop new small molecule based medicines with a potential to be developed for the treatment of diseases which are directly or indirectly controlled by the activity of RORγ1 or RORγt. Such diseases include but are not restricted to inflammatory diseases, asthma, rheumatoid arthritis, autoimmune diseases or diseases with an autoimmune component such as systemic lupus erythomatosis, inflammatory bowel disease (Crohn's disease), ulcerative colitis, inflammatory skin diseases such as atopic eczema or psoriasis, multiple sclerosis or similar diseases.

The compounds of the present invention can be prepared by a combination of methods known in the art including the procedures described in Schemes I to III below. Pyrrole-3-esters of general structure A (Scheme I) can be N-derivatized by alkylation with alkyl halides, by reaction with sulfonyl chlorides or sulfamoyl chlorides in the presence of appropriate bases in appropriate solvents. The introduction of an aromatic or heteroaromatic substituents in the 5-position of intermediates B (Scheme I) can be achieved either by bromination with N-bromosuccinimide (NBS) and subsequent Suzuki cross coupling with boronic esters or boronic acids or by an Ir-catalyzed direct borylation (as described in J. Am. Chem. Soc. 2007, 129:15434) of intermediate B (Scheme I), followed by boronic ester hydrolysis and Suzuki cross coupling with halo-aromatics or halo-heteroaromatics. The order of alkylation and bromination to prepare intermediates C can be inverted as depicted in Scheme I. The common intermediate E (Scheme I) can be further transformed into carboxamides by ester hydrolysis and amide formation using methods known to those skilled in the art.

Alternatively, for purposes of tailored late stage derivatization, the formation of the amide can be performed first, followed by bromination and Suzuki cross-coupling as final step, as depicted in Scheme II.

embedded image

In alternative to Pd-catalyzed cross coupling reactions the 2-position of pyrrole A (Scheme III) can be acylated and the resulting ketone intermediate B (Scheme III) can be further transformed into heteroaromatics containing analogues of the general formula C in Scheme III, using methods described in Org. Lett. 2008, 10:2897. Again, intermediate C (Scheme III) can be further transformed into carboxamides by ester hydrolysis and amide formation using methods known to those skilled in the art.

The ligand-binding domain (LBD) of RORγ was expressed as fusion protein with GST in BL-21 (BL3) cells using the vector pDEST15. Cells were lysed by lysozyme-treatment and sonication, and the fusion proteins purified over glutathione sepharose (Pharmacia) according to the manufacturers instructions. For screening of compounds for their influence on the RORγ-peptide interaction, the LANCE technology (Perkin Elmer) was applied. This method relies on the binding dependent energy transfer from a donor to an acceptor fluorophor attached to the binding partner of interest. For ease of handling and reduction of background from compound fluorescence LANCE technology makes use of generic fluorophore labels and time resolved detection assays were done in a final volume of 25 μL in a 384 well plate, in a Tris-based buffer system (20 mM Tris-HCl pH 6.8; 60 mM KCl, 1 mM DTT; 5 mM MgCl₂; 35 ng/μL BSA), containing 20-60 ng/well recombinantly expressed RORγ-LBD fused to GST, 200-600 nM N-terminally biotinylated peptide, 200 ng/well Streptavidin-xIAPC conjugate (Prozyme) and 6-10 ng/well Eu W1024-antiGST (Perkin Elmer). DMSO content of the samples was kept at 1%.

After generation of the Tris-based buffer system, the potentially RORγ modulating ligands were diluted. After this step, protein, peptide and fluorescent acceptor and donor solutions were mixed in the Tris-based buffer system and have been added to the compound dilutions, after this addition of ‘detection mix’, the assay was equilibrated for 1 h in the dark at rt in FIA-plates black 384 well (Corning). The LANCE signal was detected by a Perkin Elmer EnVision™ Multilabel Counter. The results were visualized by plotting the ratio between the emitted light at 665 nm and 615 nm. A basal level of RORγ-peptide formation is observed in the absence of added ligand. Ligands that promote the complex formation induce a concentration-dependent increase in time-resolved fluorescent signal. Compounds which bind equally well to both monomeric RORγ and to the RORγ-peptide complex would be expected to give no change in signal, whereas ligands, which bind preferentially to the monomeric receptor would be expected to induce a concentration-dependent decrease in the observed signal.

To assess the antagonistic potential of the compounds, IC₅₀values were determined using a Ligand Sensing Assay based on Time-resolved Fluorescence Energy Transfer (TR-FRET) as described above. The normalised TR-FRET assay values, using the following equation: 1000*665 nm measurement value/615 nm measurement value, were transferred to the program GraphPad Prism to generate graphs and dose response curves using the following equation:

- Equation: Sigmoidal dose-response (variable slope)

Y=Bottom+(Top−Bottom)/(1+10̂((Log EC50−X)*HillSlope))

X is the logarithm of the concentration. Y is the response.

Y starts at Bottom and goes to Top with a sigmoidal shape.

This is identical to the “four parameter logistic equation”. The IC₅₀values are calculated using this equation. Examples listed below do reduce the signal in the TR-FRET assay in a dose dependent manner. The Examples of the present invention usually have an inhibition activity (IC₅₀FRET) ranging from below 100 nM to about 20 μM and typically, from about 150 nM to about 2 μM. The RORγ modulating compounds of the invention desirably have an inhibition in the TR-FRET Activity Assay ranging from below 150 nM to about 2 μM. Table 2 lists the pIC₅₀-value of compounds of the invention (FRET). Is is understood that the data illustrated below may have reasonable variation depending on the specific conditions and procedures used by the person conducting the test. The efficacy was determined in comparison to the RORγt inhibitor T0901317 (equals 100%) and the pIC₅₀-value is underlined, when the efficacy of the compound is below 50% of the reference.

RORγ Gal4 Reporter Gene Assay

Determination of a ligand mediated Gal4 promoter driven transactivation to quantify ligand binding to RORγ was performed as follows: DNA encoding three different RORγ protein fragments was cloned into vector pCMV-BD (Stratagene). Expression was under control of a CMV promoter and as fusion to the DNA-binding domain of the yeast protein GAL4. The amino acid boundaries of the three proteins and the respective database entries are listed in Table 3. Other vectors used were pFR-Luc (Stratagene) as regulated reporter plasmid. pFR-Luc contains a synthetic promoter with five tandem repeats of the yeast GAL4 binding sites that control expression of the Photinus pyralis (American firefly) luciferase gene. In order to improve experimental accuracy the plasmid pRL-CMV was cotransfected. pRL-CMV contains the constitutive CMV promoter, controlling the expression of the Renilla reniformis luciferase.

All Gal4 reporter gene assays were done in 293T cells (DSMZ (German Collection of Microorganisms and Cell Cultures), Braunschweig, Germany, ACC635) grown in Minimum Essential Medium (MEM) with Phenol Red. The medium is supplemented with 10% fetal bovine serum, 0.1 mM nonessential amino acids, 1 mM sodium pyruvate, 1% Glutamax and 100 units Penicillin/Streptavidin per mL at 37° C. in 5% CO₂.

For the assay, 5×10⁵cells were plated per well in 96 well plates in 100 μL per well, incubated over night at 37° C. in 5% CO₂. The following day, medium was discarded and the cells were transiently transfected using 20 μL per well of a OptiMEM-PEI-based transfection-reagent (Sigma-Aldrich, 408727) including the three plasmids described above. About 4 h after addition of the transfection solution, fresh MEM (same composition as used for plating cells, but without serum) was added. Then compound stocks, prediluted in MEM (same composition as used for plating cells) were added (final vehicle concentration not exceeding 0.1%).

Cells were incubated for additional 16 h before firefly (FF) and renilla (REN) luciferase activities were measured sequentially in the same cell extract using a Dual-Light-Luciferase-Assay system (Dyer et al., Anal. Biochem. 2000, 282:158). All experiments were done in triplicates.

Applying the Gal4 reporter gene assay as described above, the Examples of the present invention usually have an inhibition activity (IC₅₀FF resp. IC₅₀RENnorm) ranging from below 5 nM to about 20 μM and typically, from about 10 nM to about 2 μM. The RORγ modulating compounds of the invention desirably have an inhibition in the Gal4 reporter gene assay ranging from below 5 nM to about 1 μM. Table 2 list the pIC₅₀-value of typical examples of compounds of the invention that have an RORγ activity in the Gal4 reporter gene assay for firefly (FF) and renilla normalised (REN) luciferase measurements. Is is understood that the data illustrated below may have reasonable variation depending on the specific conditions and procedures used by the person conducting the test. The efficacy was determined in comparison to the RORγt inhibitor T0901317 (equals 100%) and the pIC₅₀-value is underlined, when the efficacy of the compound is below 50% of the reference.
