FIELD OF THE INVENTION

The invention is directed to substituted thiazole compounds, which are modulators of the nuclear receptor RORγt, pharmaceutical compositions, and methods for use thereof. More particularly, the RORγt modulators are useful for preventing, treating or ameliorating an RORγt mediated inflammatory syndrome, disorder or disease.

BACKGROUND OF THE INVENTION

Retinoic acid-related nuclear receptor gamma t (RORγt) is a nuclear receptor, exclusively expressed in cells of the immune system, and a key transcription factor driving Th17 cell differentiation. Th17 cells are a subset of CD4+ T cells, expressing CCR6 on their surface to mediate their migration to sites of inflammation, and dependent on IL-23 stimulation, through the IL-23 receptor, for their maintenance and expansion. Th17 cells produce several proinflammatory cytokines including IL-17A, IL-17F, IL-21, and IL-22 (Korn, T., E. Bettelli, et al. (2009). “IL-17 and Th17 Cells.” Annu Rev Immunol 27: 485-517.), which stimulate tissue cells to produce a panel of inflammatory chemokines, cytokines and metalloproteases, and promote recruitment of granulocytes (Kolls, J. K. and A. Linden (2004). “Interleukin-17 family members and inflammation.” Immunity 21(4): 467-76; Stamp, L. K., M. J. James, et al. (2004). “Interleukin-17: the missing link between T-cell accumulation and effector cell actions in rheumatoid arthritis” Immunol Cell Biol 82(1): 1-9). Th17 cells have been shown to be the major pathogenic population in several models of autoimmune inflammation, including collagen-induced arthritis (CIA) and experimental autoimmune encephalomyelitis (EAE) (Dong, C. (2006). “Diversification of T-helper-cell lineages: finding the family root of IL-17-producing cells.” Nat Rev Immunol 6(4): 329-33; McKenzie, B. S., R. A. Kastelein, et al. (2006). “Understanding the IL-23-IL-17 immune pathway.” Trends Immunol 27(1): 17-23.). RORγt-deficient mice are healthy and reproduce normally, but have shown impaired Th17 cell differentiation in vitro, a significantly reduced Th17 cell population in vivo, and decreased susceptibility to EAE (Ivanov, II, B. S. McKenzie, et al. (2006). “The orphan nuclear receptor RORgammat directs the differentiation program of proinflammatory IL-17+ T helper cells.” Cell 126(6): 1121-33.). Mice deficient for IL-23, a cytokine required for Th17 cell survival, fail to produce Th17 cells and are resistant to EAE, CIA, and inflammatory bowel disease (IBD) (Cua, D. J., J. Sherlock, et al. (2003). “Interleukin-23 rather than interleukin-12 is the critical cytokine for autoimmune inflammation of the brain.” Nature 421(6924): 744-8; Langrish, C. L., Y. Chen, et al. (2005). “IL-23 drives a pathogenic T cell population that induces autoimmune inflammation.” J Exp Med 201(2): 233-40; Yen, D., J. Cheung, et al. (2006). “IL-23 is essential for T cell-mediated colitis and promotes inflammation via IL-17 and IL-6.” J Clin Invest 116(5): 1310-6.). Consistent with these findings, an anti-IL23-specific monoclonal antibody blocks development of psoriasis-like inflammation in a murine disease model (Tonel, G., C. Conrad, et al. “Cutting edge: A critical functional role for IL-23 in psoriasis.” J Immunol 185(10): 5688-91).

RORγT deficient mice exhibited resistance to learned helplessness. Treatment with the RORγT inhibitor SR1001, or anti-interleukin-17A antibodies reduced Th17-dependent learned helplessness (Beurel, E., Harrington, L. E., Jope, R. S. (2013) “Inflammatory T helper 17 cells promote depression-like behavior in mice.” Biol Psychiatry 73(7): 622-30). In human patients with major depressive disorder, both peripheral blood lymphocyte RORγT mRNA expression and peripheral Th17 cells were found to be elevated relative to the control group (Chen, Y., et al. (2011). “Emerging tendency towards autoimmune process in major depressive patients: A novel insight from Th17 cells.” Psychiatry Research 188(2): 224-230).

Administration of RORγ inverse agonist SR1555 to obese diabetic mice resulted in a modest reduction in food intake accompanied with significant reduction in fat mass, resulting in reduced body weight and improved insulin sensitivity (Chang, M. R. et al. (2015) “Antiobesity Effect of a Small Molecule Repressor of RORγ.” Mol Pharmacol. 88(1): 48-56). In addition, Rorγ−/− mice are protected from hyperglycemia and insulin resistance in the state of obesity (Meissburger, B. et al. (2011) “Adipogenesis and insulin sensitivity in obesity are regulated by retinoid-related orphan receptor gamma.” EMBO Mol Med. 3(11): 637-651).

In humans, a number of observations support the role of the IL-23/Th17 pathway in the pathogenesis of inflammatory diseases. IL-17, the key cytokine produced by Th17 cells, is expressed at elevated levels in a variety of allergic and autoimmune diseases (Barczyk, A., W. Pierzchala, et al. (2003). “Interleukin-17 in sputum correlates with airway hyperresponsiveness to methacholine.” Respir Med 97(6): 726-33.; Fujino, S., A. Andoh, et al. (2003). “Increased expression of interleukin 17 in inflammatory bowel disease.” Gut 52(1): 65-70.; Lock, C., G. Hermans, et al. (2002). “Gene-microarray analysis of multiple sclerosis lesions yields new targets validated in autoimmune encephalomyelitis.” Nat Med 8(5): 500-8.; Krueger, J. G., S. Fretzin, et al. “IL-17A is essential for cell activation and inflammatory gene circuits in subjects with psoriasis.” J Allergy Clin Immunol 130(1): 145-154 e9.). Furthermore, human genetic studies have shown association of polymorphisms in the genes for Th17 cell-surface receptors, IL-23R and CCR6, with susceptibility to IBD, multiple sclerosis (MS), rheumatoid arthritis (RA) and psoriasis (Gazouli, M., I. Pachoula, et al. “NOD2/CARD15, ATG16L1 and IL23R gene polymorphisms and childhood-onset of Crohn's disease.” World J Gastroenterol 16(14): 1753-8., Nunez, C., B. Dema, et al. (2008). “IL23R: a susceptibility locus for celiac disease and multiple sclerosis?” Genes Immun 9(4): 289-93.; Bowes, J. and A. Barton “The genetics of psoriatic arthritis: lessons from genome-wide association studies.” Discov Med 10(52): 177-83; Kochi, Y., Y. Okada, et al. “A regulatory variant in CCR6 is associated with rheumatoid arthritis susceptibility.” Nat Genet 42(6): 515-9.).

Ustekinumab (Stelara®), an anti-p40 monoclonal antibody blocking both IL-12 and IL-23, is approved for the treatment of adult patients (18 years or older), with moderate to severe plaque psoriasis, who are candidates for phototherapy or systemic therapy. Currently, monoclonal antibodies specifically targeting only IL-23, to more selectively inhibit the Th17 subset, are also in clinical development for psoriasis (Garber K. (2011). “Psoriasis: from bed to bench and back” Nat Biotech 29, 563-566), further implicating the important role of the IL-23- and RORγt-driven Th17 pathway in this disease. Results from recent phase II clinical studies strongly support this hypothesis, as anti-IL-17 receptor and anti-IL-17 therapeutic antibodies both demonstrated high levels of efficacy in patients with chronic psoriasis (Papp, K. A., “Brodalumab, an anti-interleukin-17-receptor antibody for psoriasis.” N Engl J Med 2012 366(13): 1181-9.; Leonardi, C., R. Matheson, et al. “Anti-interleukin-17 monoclonal antibody ixekizumab in chronic plaque psoriasis.” N Engl J Med 366(13): 1190-9.). Anti-IL-17 antibodies have also demonstrated clinically relevant responses in early trials in RA and uveitis (Hueber, W., Patel, D. D., Dryja, T., Wright, A. M., Koroleva, I., Bruin, G., Antoni, C., Draelos, Z., Gold, M. H., Durez, P., Tak, P. P., Gomez-Reino, J. J., Foster, C. S., Kim, R. Y., Samson, C. M., Falk, N. S., Chu, D. S., Callanan, D., Nguyen, Q. D., Rose, K., Haider, A., Di Padova, F. (2010) Effects of AIN457, a fully human antibody to interleukin-17A, on psoriasis, rheumatoid arthritis, and uveitis. Sci Transl Med 2, 5272.).

All the above evidence supports inhibition of the Th17 pathway by modulating RORγt activity as an effective strategy for the treatment of immune-mediated inflammatory diseases.

Methods of Use

The present invention is directed to a method for preventing, treating or ameliorating a RORγt mediated inflammatory syndrome, disorder or disease comprising administering to a subject in need thereof an effective amount of a compound of Formula I or a form, composition or medicament thereof.

Since RORγt is an N-terminal isoform of RORγ, it is recognized that compounds of the present invention which are modulators of RORγt are likely to be modulators of RORγ as well. Therefore the mechanistic description “RORγt modulators” is intended to encompass RORγ modulators as well.

When employed as RORγt modulators, the compounds of the invention may be administered in an effective amount within the dosage range of about 0.5 mg to about 10 g, preferably between about 0.5 mg to about 5 g, in single or divided daily doses. The dosage administered will be affected by factors such as the route of administration, the health, weight and age of the recipient, the frequency of the treatment and the presence of concurrent and unrelated treatments.

It is also apparent to one skilled in the art that the therapeutically effective dose for compounds of the present invention or a pharmaceutical composition thereof will vary according to the desired effect. Therefore, optimal dosages to be administered may be readily determined by one skilled in the art and will vary with the particular compound used, the mode of administration, the strength of the preparation, and the advancement of the disease condition. In addition, factors associated with the particular subject being treated, including subject age, weight, diet and time of administration, will result in the need to adjust the dose to an appropriate therapeutic level. The above dosages are thus exemplary of the average case. There can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention.

The compounds of Formula I may be formulated into pharmaceutical compositions comprising any known pharmaceutically acceptable carriers. Exemplary carriers include, but are not limited to, any suitable solvents, dispersion media, coatings, antibacterial and antifungal agents and isotonic agents. Exemplary excipients that may also be components of the formulation include fillers, binders, disintegrating agents and lubricants.

The pharmaceutically-acceptable salts of the compounds of Formula I include the conventional non-toxic salts or the quaternary ammonium salts which are formed from inorganic or organic acids or bases. Examples of such acid addition salts include acetate, adipate, benzoate, benzenesulfonate, citrate, camphorate, dodecylsulfate, hydrochloride, hydrobromide, lactate, maleate, methanesulfonate, nitrate, oxalate, pivalate, propionate, succinate, sulfate and tartrate. Base salts include ammonium salts, alkali metal salts such as sodium and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases such as dicyclohexylamino salts and salts with amino acids such as arginine. Also, the basic nitrogen-containing groups may be quaternized with, for example, alkyl halides.

The pharmaceutical compositions of the invention may be administered by any means that accomplish their intended purpose. Examples include administration by parenteral, subcutaneous, intravenous, intramuscular, intraperitoneal, transdermal, buccal or ocular routes. Alternatively or concurrently, administration may be by the oral route. Suitable formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form, for example, water-soluble salts, acidic solutions, alkaline solutions, dextrose-water solutions, isotonic carbohydrate solutions and cyclodextrin inclusion complexes.

The present invention also encompasses a method of making a pharmaceutical composition comprising mixing a pharmaceutically acceptable carrier with any of the compounds of the present invention. Additionally, the present invention includes pharmaceutical compositions made by mixing a pharmaceutically acceptable carrier with any of the compounds of the present invention.

Polymorphs and Solvates

Furthermore, the compounds of the present invention may have one or more polymorph or amorphous crystalline forms and as such are intended to be included in the scope of the invention. In addition, the compounds may form solvates, for example with water (i.e., hydrates) or common organic solvents. As used herein, the term “solvate” means a physical association of the compounds of the present invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. The term “solvate” is intended to encompass both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like.

It is intended that the present invention include within its scope polymorphs and solvates of the compounds of the present invention. Thus, in the methods of treatment of the present invention, the term “administering” shall encompass the means for treating, ameliorating or preventing a syndrome, disorder or disease described herein with the compounds of the present invention or a polymorph or solvate thereof, which would obviously be included within the scope of the invention albeit not specifically disclosed.

In another embodiment, the invention relates to a compound as described in Formula I for use as a medicament.

In another embodiment, the invention relates to the use of a compound as described in Formula I for the preparation of a medicament for the treatment of a disease associated with an elevated or aberrant RORγt activity.

The present invention includes within its scope prodrugs of the compounds of this invention. In general, such prodrugs will be functional derivatives of the compounds which are readily convertible in vivo into the required compound. Thus, in the methods of treatment of the present invention, the term “administering” shall encompass the treatment of the various disorders described with the compound specifically disclosed or with a compound which may not be specifically disclosed, but which converts to the specified compound in vivo after administration to the patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, Ed. H. Bundgaard, Elsevier, 1985.

Furthermore, it is intended that within the scope of the present invention, any element, in particular when mentioned in relation to a compound of Formula I, shall comprise all isotopes and isotopic mixtures of said element, either naturally occurring or synthetically produced, either with natural abundance or in an isotopically enriched form. For example, a reference to hydrogen includes within its scope ¹H, ²H (D), and ³H (T). Similarly, references to carbon and oxygen include within their scope respectively ¹²C, ¹³C and ¹⁴C and ¹⁶O and ¹⁸O. The isotopes may be radioactive or non-radioactive. Radiolabelled compounds of Formula I may comprise a radioactive isotope selected from the group of ³H, ¹¹C, ¹⁸F, ¹²²I, ¹²³I, ¹²⁵I, ¹³¹I, ⁷⁵Br, ⁷⁶Br, ⁷⁷Br and ⁸²Br. Preferably, the radioactive isotope is selected from the group of ³H, ¹¹C and ¹⁸F.

Some compounds of the present invention may exist as atropisomers. Atropisomers are stereoisomers resulting from hindered rotation about single bonds where the steric strain barrier to rotation is high enough to allow for the isolation of the conformers. It is to be understood that all such conformers and mixtures thereof are encompassed within the scope of the present invention.

Where the compounds according to this invention have at least one stereo center, they may accordingly exist as enantiomers or diastereomers. It is to be understood that all such isomers and mixtures thereof are encompassed within the scope of the present invention.

Where the processes for the preparation of the compounds according to the invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form, or individual enantiomers may be prepared either by enantiospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation of diastereomeric pairs by salt formation with an optically active acid, such as (−)-di-p-toluoyl-D-tartaric acid and/or (+)-di-p-toluoyl-L-tartaric acid followed by fractional crystallization and regeneration of the free base. The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral column vial HPLC or SFC. In some instances rotamers of compounds may exist which are observable by 1H NMR leading to complex multiplets and peak integration in the 1H NMR spectrum.

Chiral centers, of which the absolute configuration is known, are labelled by prefixes R and S, assigned by the standard sequence-rule procedure, and preceded when necessary by the appropriate locants. Chiral centers, of which the relative but not the absolute configuration is known, are labelled arbitrarily by prefixes R* and S*, preceded when necessary by the appropriate locants. These prefixes are assigned by the standard sequence-rule procedure on the arbitrary assumption that the center of chirality with the lowest locant has chirality R. When a compound contains chiral centers with known absolute configurations and a sterically unrelated set of chiral centers with known relative configurations but unknown absolute configurations, then R* and S* are used to designate the latter. (Pure & Appl. Chem. 45, 1976, 11-30).

During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J. F. W. McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known from the art.

General Schemes:

Compounds of Formula I in the present invention can be synthesized in accordance with the general synthetic methods known to those who are skilled in the art. The following reaction schemes are only meant to represent examples of the invention and are in no way meant to be a limit of the invention.

The compounds of the present invention can be prepared according to Schemes 1-3. Coupling of a 3-pyridyl group to the thiazole ring of compounds of Formula I can be accomplished by coupling the 5-bromopyridine building blocks C-I to the thiazole derivatives B-I in the presence of palladium catalysis, using appropriate ligands, solvents, additives and temperatures to form the 5-(3-pyridyl)-substituted thiazoles A-I (Scheme 1). Alternatively, 5-(3-pyridyl)-substituted thiazoles A-II can be prepared by the coupling of 5-bromopyridine building blocks C-I to thiazole esters B-III in the presence of palladium catalysis, using appropriate ligands, solvents, additives and temperatures. Subsequent ester hydrolysis, using reagents such as potassium tert-butoxide in solvents such as THF, and amide bond formation using reagents such as HATU and DIPEA in solvents such as DMF then provides 5-(3-pyridyl)-substituted thiazoles A-I. Alternatively, direct aminolysis of esters A-II with amines in solvents such as EtOH then affords 5-(3-pyridyl)-substituted thiazoles A-I. When employing hydrochloride salts of amines, direct aminolysis is achieved in suitable solvents such as EtOH in the presence of bases such as DIPEA. In some cases, hydrolysis of esters A-II using reagents such as DIPEA in solvents such as EtOH and water afforded the corresponding carboxylic acids, which were then converted to the corresponding acid chlorides using reagents such as oxallyl chloride and DMF in solvents such as DCM. Amide bond formation could then be achieved using amines in the presence of DIPEA in solvents such as DCM to afford substituted thiazoles A-I.

Preparation of the 2-amino-5-bromopyridines C-I are shown in Scheme 2. 2-Amino-5-bromopyridines C-I can be prepared by direct amination of 5-bromo-2-chloropyridines C-II with amines under microwave conditions. Alternatively, when employing hydrochloride salts of amines, direct amination is achieved in suitable solvents such as acetonitrile in the presence of bases such as DIPEA. Direct amination of 2-bromopyridines C-III with amines under microwave conditions affords intermediates C-IV. Alternatively, intermediates C-IV are prepared by direct amination of 2-chloropyridines C-V with hydrochloride salts of amines in suitable solvents such as acetonitrile in the presence of bases such as DIPEA, or by direct amination of 2-fluoropyridines C-VI with hydrochloride salts of amines in suitable solvents such as DMSO in the presence of bases such as NaHCO₃. In addition, 2-aminopyridines C-IV may be prepared by a palladium mediated amination of 2-bromopyridines C-III or 2-chloropyridines C-V using reagents such as Pd₂(dba)₃. Bromination using reagents such as NBS or bromine affords 2-amino-5-bromopyridines C-I.

The preparation of thiazole derivatives B-I is shown in Scheme 3. B-I can be prepared starting from 2-(alkoxycarbonyl)thiazole-4-carboxylic acid B-II by a process involving standard methods for amide bond formation, ester hydrolysis and a second amide bond formation. Alternatively, intermediates B-III can undergo a direct aminolysis with amines in appropriate solvents and temperatures to afford B-I. Thiazoles B-I can also be prepared by formation of tert-butyl ester B-IV from B-II using tert-butanol and TsCl in the presence of bases such as pyridine. Subsequent selective ester hydrolysis at the 2-position of the thiazole ring and amide bond formation then affords B-V. Alternatively B-V can be formed from B-IV by direct aminolysis with amines in appropriate solvents and temperatures. Subsequent ester hydrolysis using reagents such as TFA followed by amide bond formation then provides B-I.

In Vitro Biological Data

ThermoFluor® Assay

ThermoFluor® is a fluorescence based assay that estimates ligand binding affinities by measuring the effect of a ligand on protein thermal stability (Pantoliano, M. W., Petrella, E. C., Kwasnoski, J. D., Lobanov, V. S., Myslik, J., Graf, E., Carver, T., Asel, E., Springer, B. A., Lane, P., and Salemme, F. R. (2001) High-density miniaturized thermal shift assays as a general strategy for drug discovery. J Biomol Screen 6, 429-40, and Matulis, D., Kranz, J. K., Salemme, F. R., and Todd, M. J. (2005) Thermodynamic stability of carbonic anhydrase: measurements of binding affinity and stoichiometry using ThermoFluor. Biochemistry 44, 5258-66). This approach is applicable to a wide variety of systems, and rigorous in theoretical interpretation through quantitation of equilibrium binding constants (K_D).

In a ThermoFluor® experiment where protein stability is monitored as the temperature is steadily increased, an equilibrium binding ligand causes the midpoint of an unfolding transition (T_m) to occur at a higher temperature. The shift in the melting point described as a ΔT_m is proportional to the concentration and affinity of the ligand. The compound potency may be compared as a rank order of either ΔT_m values at a single compound concentration or in terms of K_D values, estimated from concentration response curves.

RORγt ThermoFluor® Assay Construct

For the RORγt construct used in the ThermoFluor® assay, numbering for the nucleotide sequences was based on the reference sequence for human RORγt, transcript variant 2, NCBI Accession: NM_001001523.1 (SEQ ID NO:1). Nucleotides 850-1635 (SEQ ID NO:2) coding for the wild type human RORγt ligand binding domain (RORγt LBD) were cloned into the pHIS1 vector, a modified pET E. coli expression vector (Accelagen, San Diego), containing an in-frame N-terminal His-tag and a TurboTEV protease cleavage site (ENLYFQG, SEQ ID NO:3) upstream of the cloned insert sequence. The amino acid sequence for the RORγt construct used in the Thermofluor® assay is shown as SEQ ID NO:4.

ThermoFluor® experiments were carried out using instruments owned by Janssen Research and Discovery, L.L.C. through its acquisition of 3-Dimensional Pharmaceuticals, Inc. 1,8-ANS (Invitrogen) was used as a fluorescent dye. Protein and compound solutions are dispensed into black 384-well polypropylene PCR microplates (Abgene) and overlayed with silicone oil (1 μL, Fluka, type DC 200) to prevent evaporation.

Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1° C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >6 OD cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature. Reference wells contained RORγt without compounds, and the assay conditions were as follows:

• • 0.065 mg/mL RORγt
  • 60 μM 1,8-ANS
  • 100 mM Hepes, pH 7.0
  • 10 mM NaCl
  • 2.5 mM GSH
  • 0.002% Tween-20

Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (×=46 nL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

The binding affinity was estimated as described previously (Matulis, D., Kranz, J. K., Salemme, F. R., and Todd, M. J. (2005) Thermodynamic stability of carbonic anhydrase: measurements of binding affinity and stoichiometry using ThermoFluor®. Biochemistry 44, 5258-66) using the following thermodynamic parameters of protein unfolding:

Reference RORγt Tm: 47.8° C.

ΔH_(Tm)=115 kcal/mol

ΔC_p(Tm)=3 kcal/mol

Cell Based Biological Data

RORγt (Full-Length Human) Reporter Assay:

Three similar reporter assay protocols, shown below, have been used to test the functional activity of RORγt modulatory compounds on transcriptional activation driven by full-length human RORγt. All three provide similar data and can be used interchangeably.

Conditions A

Cells used in this assay were transiently co-transfected with three different plasmids, one expressing the GAL4-DNA binding domain (DBD)-RORγt fusion protein under control of a CMV promoter (NH2-Gal4-DBD:RORC-COOH in pCMV-BD, Stratagene #211342), and two reporter plasmids—the firefly luciferase reporter under control of a GAL4 promoter (pFR-Luc 2×GAL4) and Renilla luciferase reporter under control of CMV promoter (pRL-CMV, Promega # E2261). The full-length coding sequence was used for human RORγt, i.e., nucleotides 142-1635 of human RORγt, transcript variant 2, NCBI Accession: NM_001001523.1 (SEQ ID NO:1). HEK293T cells were plated at 35000 per well in 96-well plate in medium of MEM with 8.6% FBS. After 18-22 hours incubation, the transfection was carried out by using a PEI solution with 170.5 ng total DNA/well (50 ng pCMV-BD-ROR plus 20 ng of pFR-Luc reporter and 0.5 ng of pRL-CMV reporter plus 100 ng Carrier DNA (Clontech #630440) for each well). 4-6 hours after transfection, cells were treated with compounds for overnight in the medium with final concentration of FBS 1.1% and DMSO 0.1%. After overnight (16 to 20 hours) incubation, media were removed and cells were lysed with 20 μL 1× Passive Lysis Buffer (Promega) for 10-15 minutes. Luminescence was measured using a BMG LUMIstar OPTIMA plate reader, after addition of 75 μL/well firefly luciferase buffer, followed by 75 μL/well Renilla luciferase buffer. To calculate the effect of compounds on RORγt activity, firefly values were normalized against values of DMSO only and values of reference compound at saturating concentration, then further normalized against Renilla signals. IC₅₀s were generated by plotting final Renilla normalized data against compound concentration and percent inhibition was calculated against DMSO control.

Conditions B

Cells used in this assay were transiently co-transfected with three different plasmids, one expressing the GAL4-DNA binding domain (DBD)-RORγt fusion protein under control of a CMV promoter (NH2-Gal4-DBD:RORC-COOH in pCMV-BD, Stratagene #211342), and two reporter plasmids—the firefly luciferase reporter under control of a GAL4 promoter (pFR-Luc 2×GAL4) and Renilla luciferase reporter under control of CMV promoter (pRL-CMV, Promega # E2261). The full-length coding sequence was used for human RORγt, i.e., nucleotides 142-1635 of human RORγt, transcript variant 2, NCBI Accession: NM_001001523.1 (SEQ ID NO:1). HEK293T cells were plated at 35,000 per well in 96-well plate in medium of DMEM with 10% FBS. After 18-22 hours incubation, the transfection was carried out by using a PEI solution with 170.5 ng total DNA/well (50 ng pCMV-BD-ROR plus 20 ng of pFR-Luc reporter and 0.5 ng of pRL-CMV reporter plus 100 ng Carrier DNA (Clontech #630440) for each well). 4-6 hours after transfection, cells were treated with compounds for overnight in the medium with final concentration of FBS 1.3% and DMSO 0.1%. After overnight (16 to 20 hours) incubation, media were removed and cells were lysed with 50 μL Glo Lysis Buffer (Promega) for 10-15 minutes followed by 10 minute incubation with 50 μL Dual Glo reagent (Promega) at room temperature. Firefly luciferase luminescence was measured using a BMG Pherastar plate reader. To each well, 50 μL Stop and Glo reagent was added and incubated for 10 minutes at room temperature. Renilla luminescence was measured using a BMG Pherastar plate reader. To calculate the effect of compounds on RORγt activity, firefly values were normalized against values of DMSO only and values of reference compound at saturating concentration, then further normalized against Renilla signals. IC50s were generated by plotting final Renilla normalized data against compound concentration and percent inhibition was calculated against DMSO control.

Conditions C

Cells used in this assay were transiently co-transfected with three different plasmids, one expressing the GAL4-DNA binding domain (DBD)-RORγt fusion protein under control of a CMV promoter (NH₂-Gal4-DBD:RORC-COOH in pCMV-BD, Stratagene #211342), and two reporter plasmids—the firefly luciferase reporter under control of a GAL4 promoter (pFR-Luc 2×GAL4) and Renilla luciferase reporter under control of CMV promoter (pRL-CMV, Promega # E2261). The full-length coding sequence was used for human RORγt, i.e., nucleotides 142-1635 of human RORγt, transcript variant 2, NCBI Accession: NM_001001523.1 (SEQ ID NO:1). HEK293T cells were plated at 8750 cells per well in 384-well plate in medium of DMEM with 10% FBS. After 18-22 hours incubation, the transfection was carried out by using a PEI solution with 42.6 ng total DNA/well (12.5 ng pCMV-BD-ROR plus 5 ng of pFR-Luc reporter and 0.125 ng of pRL-CMV reporter plus 25 ng Carrier DNA (Clontech #630440) for each well). 4-6 hours after transfection, cells were treated with compounds for overnight in the medium with final concentration of FBS 1.3% and DMSO 0.1%. After overnight (16 to 20 hours) incubation, media were removed and cells were lysed with 20 μL Glo Lysis Buffer (Promega) for 10-15 minutes followed by 10 minute incubation with 20 μL Dual Glo reagent (Promega) at room temperature. Firefly luciferase luminescence was measured using a BMG Pherastar plate reader. To each well, 20 μL Stop and Glo reagent was added and incubated for 10 minutes at room temperature. Renilla luminescence was measured using a BMG Pherastar plate reader. To calculate the effect of compounds on RORγt activity, firefly values were normalized against values of DMSO only and values of reference compound at saturating concentration, then further normalized against Renilla signals. IC₅₀s were generated by plotting final Renilla normalized data against compound concentration and percent inhibition was calculated against DMSO control.

Human Th17 Assay

The human Th17 assay tests the effect of RORγt modulatory compounds on IL-17 production by CD4 T cells under conditions which favor Th17 differentiation. Total CD4⁺ T cells were isolated from the peripheral blood mononuclear cells (PBMC) of healthy donors using a CD4⁺ T cell isolation kit II, following the manufacturer's instructions (Miltenyi Biotec). Cells were resuspended in a medium of RPMI-1640 supplemented with 10% fetal bovine serum, penicillin, streptomycin, glutamate, and β-mercaptoethanol and were added to 96-well plates at 1.5×10⁵ per 100 μL per well. 50 μL of compound at titrated concentrations in DMSO were added into each well at final DMSO concentration at 0.2%. Cells were incubated for 1 hour, then 50 μL of Th17 cell differentiation medium was added to each well. The final concentrations of antibodies and cytokines (R&D Systems) in differentiation medium were: 3×10⁶/mL anti-CD3/CD28 beads (prepared using human T cell activation/expansion kit, Miltenyi Biotec), 10 μg/mL anti-IL4, 10 μg/mL anti-IFNγ, 10 ng/mL IL1β, 10 ng/mL IL23, 50 ng/mL IL6, 3 ng/mL TGFβ and 20 U/mL IL2. Cells were cultured at 37° C. and 5% CO₂ for 3 days. Supernatants were collected and the accumulated IL-17 in culture was measured by using MULTI-SPOT® Cytokine Plate following manufacture's instruction (Meso Scale Discovery). The plate was read using Sector Imager 6000, and IL-17 concentration was extrapolated from the standard curve. The IC50s were determined by GraphPad.
