     The present invention relates to compounds according to general formula (I) 
     
       
         
         
             
             
         
       
     
     which act as modulators of the glucocorticoid receptor and can be used in the treatment and/or prophylaxis of disorders which are at least partially mediated by the glucocorticoid receptor. 
     Glucocorticoids (GC) exert strong anti-inflammatory, immunosuppressive and disease-modifying therapeutic effects mediated by the glucocorticoid receptor (GR). They have been widely used to treat inflammatory and immune diseases for decades and still represent the most effective therapy in those conditions. However, chronic GC treatment of inflammatory diseases is hampered by GC-associated adverse effects. These undesired side effects include insulin resistance, diabetes, hypertension, glaucoma, depression, osteoporosis, adrenal suppression and muscle wasting with osteoporosis and diabetes being the most severe ones from the physician&#39;s point of view (Hapgood JP. et al., Pharmacol Ther. 2016 September; 165: 93-113; Buttgereit F. el al, Clin Exp Rheumatol. 2015 July-August; 33(4 Suppl 92):529-33; Hartmann K et al, Physiol Rev. 2016 April; 96(2):409-47). 
     One example of an oral glucocorticoid is prednisone which is frequently prescribed for the treatment of several inflammatory disorders (De Bosscher K et al., Trends Pharmacol Sci. 2016 January; 37(1):4-16; Buttgereit F. et al.,  JAMA.  2016; 315(22):2442-2458). As GC cause adrenal suppression, prednisolone withdrawal symptoms can be severe if the drug is discontinued abruptly when all the signs of the disease have disappeared. Thus gradual GC tapering to physiological doses is frequently part of treatment protocols to reduce the risk of relapse and other withdrawal symptoms (Liu D. et al., Allergy Asthma Clin Immunol. 2013 Aug. 15; 9(1):30). Therefore, there is high medical need for novel potent anti-inflammatory drugs with less adverse effects. 
     Recent research has focused on the development of partial agonists or selective glucocorticoid receptor modulators which activate the pathways for the inhibition of inflammation but avoid targeting the pathways that lead to the GC-associated adverse effects. Most of these effects have been demonstrated to be mediated by different GR-dependent genomic mechanisms termed transactivation and transrepression. The anti-inflammatory actions of GC are mainly attributable to the transrepression of inflammatory genes while certain side effects are predominantly mediated via transactivation of several genes. According to the nature of a ligand the GR can be selectively modulated in a specific conformation which favors transrepression over transactivation resulting in an improved therapeutic benefit (De Bosscher K et al., Trends Pharmacol Sci. 2016 January; 37(1):4-16). The concept of such dissociating ligands was already defined about two decades ago and several compounds have been identified and were evaluated in preclinical and clinical testing but none of them has as yet been approved for clinical use. 
     Compounds which are active as modulators of the glucocorticoid receptor are also known from WO 2009/035067 and WO 2017/034006. 
     It was an object of the present invention to provide novel compounds which are modulators of the glucocorticoid receptor and which preferably have advantages over the compounds of the prior art. The novel compounds should in particular be suitable for use in the treatment and/or prophylaxis of disorders or diseases which are at least partially mediated by the glucocorticoid receptor. 
     This object has been achieved by the subject-matter disclosed herein. 
     It was surprisingly found that the compounds according to the present invention are highly potent modulators of the glucocorticoid receptor.

     The compounds according to the present invention are defined by substituents, for example by R 1 , R 2  and R 3  (1 st  generation substituents) which may optionally be for their part themselves be substituted (2 nd  generation substituents). Depending on the definition, these substituents of the substituents can optionally be for their part resubstituted (3 rd  generation substituents). If, for example, R 1 =a C 1-10 -alkyl (1 st  generation substituent), then the C 1-10 -alkyl can for its part be substituted, for example with a N(H)(C 1-6 -alkyl) (2 nd  generation substituent). This produces the functional group R 1 =(C 1-10 -alkyl-NH—C 1-6 -alkyl). The NH—C 1-6 -alkyl can then for its part be resubstituted, for example with Cl (3 rd  generation substituent). Overall, this produces the functional group R 1 =C 1-10 -alkyl-NH—C 1-6 -alkyl, wherein the C 1-6 -alkyl of the NH—C 1-6 -alkyl is substituted by Cl. However, in a preferred embodiment, the 3 rd  generation substituents may not be resubstituted, i.e. there are then no 4 th  generation substituents. More preferably, the 2 nd  generation substituents may not be resubstituted, i.e. there are no 3 rd  generation substituents. 
     If a residue occurs multiply within a molecule, then this residue can have respectively different meanings for various substituents: if, for example, both R 2  and R 3  denote C 1-6 -alkyl, then C 1-6 -alkyl can e.g. represent ethyl for R 2  and can represent methyl for R 3 .

     The compounds according to the present invention can be produced in the manner described here or in an analogous manner. 
     In a preferred embodiment, the compounds according to the present invention are modulators of the glucocorticoid receptor. In the sense of the present invention, the term “selective modulator of the glucocorticoid receptor (glucocorticoid receptor modulator)” preferably means that the respective compound exhibits in a cellular target engagement assay for agonistic or antagonistic potency on the glucocorticoid receptor an EC50 or IC50 value on the glucocorticoid receptor of at most 15 μM (10·10 −6  mol/L) or at most 10 μM; more preferably at most 1 μM; still more preferably at most 500 nM (10 −9  mol/L); yet more preferably at most 300 nM; even more preferably at most 100 nM; most preferably at most 10 nM; and in particular at most 1 nM. 
     The person skilled in the art knows how to test compounds for modulation (agonistic or antagonistic) of the activity of the glucocorticoid receptor. Preferred target engagement assays for testing compounds for their agonistic or antagonistic potency (EC50, IC50) on the glucocorticoid receptor are described herein below: 
     Glucocorticoid Receptor Cell-Based Assays 
     Potential selective glucocorticoid receptor modulators of this intervention can be tested for modulation of the activity of the glucocorticoid receptor using cell-based assays. These assays involve a Chinese hamster ovary (CHO) cell line which contains fragments of the glucocorticoid receptor as well as fusion proteins. The glucocorticoid receptor fragments used are capable of binding the ligand (e.g. beclomethasone) to identify molecules that compete for binding with glucocorticoid receptor ligands. In more detail, the glucocorticoid receptor ligand binding domain is fused to the DNA binding domain (DBD) of the transcriptionfactor GAL4 (GAL4 DBD-GR) and is stably integrated into a CHO cell line containing a GAL4-UAS-Luciferase reporter construct. To identify selective glucocorticoid receptor modulators, the reporter cell line is incubated with the molecules using an 8-point half-log compound dilution curve for several hours. After cell lysis the luminescence that is produced by luciferase after addition of the substrate is detected and EC50 or IC50 values can be calculated. Engagement of molecules which induce gene expression via glucocortocoid receptor binding to the DNA leads to expression of the luciferase gene under the control of the fusion protein GAL4 DBD-GR and therefore to a dose-dependent increase of the luminescence signal. Binding of molecules which repress beclomethasone-induced gene expression of the luciferase gene under the control of the fusion protein GAL4 DBD-GR leads to a dose-dependent reduction of the luminescence signal. 
     In a preferred embodiment, the compound according to the present invention exhibits in a cellular target engagement assay for agonistic or antagonistic potency on the glucocorticoid receptor an EC50 or IC50 value on the glucocorticoid receptor of at most 1 μM (10 −6  mol/L); still more preferably at most 500 nM (10 −9  mol/L); yet more preferably at most 300 nM; even more preferably at most 100 nM; most preferably at most 50 nM; and in particular at most 10 nM or at most 1 nM. 
     In a preferred embodiment, the compound according to the present invention exhibits in a cellular target engagement assay for agonistic or antagonistic potency on the glucocorticoid receptor an EC50 or IC50 value on the glucocorticoid receptor in the range of from 0.1 nM (10 −9  mol/L) to 1000 nM; still more preferably 1 nM to 800 nM; yet more preferably 1 nM to 500 nM; even more preferably 1 nM to 300 nM; most preferably 1 nM to 100 nM; and in particular 1 nM to 80 nM. 
     Preferably, the compounds according to the present invention are useful as selective modulators of the glucocorticoid receptor.

     The pharmaceutical dosage form according to the present invention is preferably prepared with the aid of conventional means, devices, methods and processes known in the art. The amount of the compound according to the present invention to be administered to the patient may vary and is e.g. dependent on the patients weight or age and also on the type of administration, the indication and the severity of the disorder.

Resulting reaction mixture was degassed with nitrogen for 30 min, then CuCl (1.75 g, 0.0176 mol) was added and reaction mixture was heated at 140° C. for 5 h. After completion of the starting material (monitored by TLC, 20% EA-Hexane, R f  0.4) reaction mixture was cooled to RT and filtered through celite. Celite bed was washed with EtOAc (500 mL). Resulting filtrate was poured into ice cold water (2500 mL). Resulting aqueous layer was extracted with EtOAc (2×750 mL). Total organic part was washed with water (2×750 mL), followed by brine (500 mL), dried over anhydrous Na 2 SO 4  and evaporated under reduced pressure to afford crude product.

Obtained crude product was purified by column chromatography to afford 5-fluoro-3,3,8-trimethyl-3,4-dihydro-1H-quinoxaline-2-thione (19 g, 93%) as yellow solid. 
     Step 6: To a stirred solution of 5-fluoro-3,3,8-trimethyl-3,4-dihydro-1H-quinoxaline-2-thione (20.5 g, 91.5 mmol) in THF (512 mL) was added drop wise hydrazine hydrate (13.5 mL, 274.5 mmol) at 0° C. The reaction mixture was stirred at RT for 16 h. TEA (64 mL, 457.5 mmol) followed acetyl chloride (21.5 mL, 274.5 mmol) were added to the reaction mixture drop-wise at 0° C. and stirred for 2 h at RT. After completion of starting material (monitored by LCMS) reaction mixture diluted with water (500 mL) and extracted by 10% MeOH-DCM (5×500 mL). The total organic part was washed by brine (250 mL), dried over Na 2 SO 4  and concentrated under reduced pressure to afford acetic acid (5-fluoro-3,3,8-trimethyl-3,4-dihydro-1H-quinoxalin-2-ylidene)-hydrazide (21 g, 87%, crude) as pale yellow solid. 
     Step 7: Acetic acid (5-fluoro-3,3,8-trimethyl-3,4-dihydro-1H-quinoxalin-2-ylidene)-hydrazide (10.5 g, 0.04 mol) was taken in round bottom flax (100 mL) and then cooled to −10° C. Then phosphorus oxalylchloride (18.5 ml, 0.2 mol) was added drop wise followed by drop wise addition of TEA (5.6 ml, 0.04 mol). After that the reaction mixture was stirred at −10° C. for 10 min and then 10 min at RT and finally at reflux condition for 1 h. After completion of starting material (monitored by LCMS) reaction mixture cooled to 0° C. and quenched with crushed ice water (100 mL). The aqueous part was then basified using cold aqueous ammonia solution (100 mL) drop-wise. Resulting basic aqueous was then extracted with EtOAc (3×150 mL). Total organic part was washed with brine (150 mL), dried over anhydrous Na 2 SO 4  and concentrated under reduced pressure to afford crude compound. Crude product co-distillation with MTBE twice, then trituration with hexane and dried to afford 6-fluoro-1,4,4,9-tetramethyl-4,5-dihydro-[1,2,4]triazolo[4,3-a]quinoxaline (6 g, 61%) as pale yellow solid.

     Biological Assays 
     Agonistic Mode of Action on the Glucocorticoid Receptor 
     The reporter cell line CHO-Gal4/GR consisted of a chinese hamster ovary (CHO) cell line (Leibniz Institute DSMZ—German Collection of Microorganisms and Cell Cultures GmbH: ACC-110) containing a firefly luciferase gene under the control of the GR ligand binding domain fused to the DNA binding domain (DBD) of GAL4 (GAL4 DBD-GR) stably integrated into CHO cells. This cell line was established by stable transfection of CHO cells with a GAL4-UAS-Luciferase reporter construct. In a subsequent step the ligand binding domain of the GR cloned into pIRES2-EGFP-GAL4 containing the DNA binding domain of GAL4 from pFA-AT2 was transfected. This fusion construct activated firefly luciferase expression under the control of a multimerized GAL4 upstream activation sequence (UAS). The signal of the emitted luminescence was recorded by the FLIPR TETRA . This allowed for specific detection of ligand-induced activation of the GR and therefore for the identification of compounds with agonistic properties. The GAL4/UAS reporter was premixed with a vector that constitutively expressed Renilla luciferase, which served as an internal positive control for transfection efficiency. 
     The complete culture medium for the assay was:
         DMEM F-12 (1:1) MIXTURE (LONZA cat. No: BE04-687F/U1) 500 mL   5 mL of 100 mM Sodium Pyruvate (LONZA cat. No: BE12-115E)   25 mL of 7.5% Sodium Bicarbonate (LONZA cat. No BE17-613E)   6.5 mL of 1 M Hepes (LONZA cat. No: BE17-737E)   5 mL of 100× Penicillin/Streptomycin (LONZA cat. No DE17-602E)   50 mL of Fetal Bovine Serum (Euroclone cat. No ECS 0180L)   0.25 mL of 10 mg/mL Puromycin (InvivoGen cat.: ant-pr-1)   0.5 mL of 100 mg/mL Zeocin (InvivoGen cat.: ant-zn-1)       

     Cryo-preserved CHO-Gal4/GR cells were suspended in complete medium and 5000 cells/25 μl/well were seeded into the wells of 384-well polystyrene assay plates (Thermo Scientific, cat. #4332) and cultured at 37° C., 5% CO 2  and 95% humidity. After 24 hours growth medium was carefully removed and replaced by 30111 Opti-MEM (GIBCO, cat. #31985062) as assay buffer. To test the compounds an 8-point half-log compound dilution curve was generated in 100% DMSO starting from a 2 mM stock and compounds were then diluted 1:50 in Opti-MEM. 10111 of compounds were then added to the wells containing 30 μl Opti-MEM resulting in a final assay concentration range from 10 μM to 0.003 μM in 0.5% DMSO. Compounds were tested at 8 concentrations in quadruplicate data points. Cells were incubated for 6 hour with compounds and beclometasone (Sigma, cat. #Y0000351) as control compound at 37° C., 5% CO 2  and 95% humidity in a total volume of 40 μl. Finally, cells were lysed with 20 μl of Triton/Luciferin solution and the signal of the emitted luminescence was recorded at the FLIPR TETRA  for 2 minutes. 
     The relative efficacy of a compound (% effect) was calculated based on the full effect of the agonist beclometasone: 
       % effect=((compound−min)/(max−min))×100
         [min=Opti-MEM only, max=beclometasone]       

     To calculate EC 50 , max, min and slope factor for each compound a concentration response curve was fitted by plotting % effect versus compound concentration using a 4 parameter logistic equation: 
         y=A +( B−A )/(1+((10 C )/×) D )
         [A=min y, B=max y, C=log EC 50 , D=slope]       

     Antagonistic Mode of Action on the Glucocorticoid Receptor 
     The reporter cell line CHO-Gal4/GR consisted of a chinese hamster ovary (CHO) cell line (Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH: ACC-110) containing a firefly luciferase gene under the control of the GR ligand binding domain fused to the DNA binding domain (DBD) of GAL4 (GAL4 DBD-GR) stably integrated into CHO cells. This cell line was established by stable transfection of CHO cells with a GAL4-UAS-Luciferase reporter construct. In a subsequent step the ligand binding domain of the GR cloned into pIRES2-EGFP-GAL4 containing the DNA binding domain of GAL4 from pFA-AT2 was transfected. This fusion construct activated firefly luciferase expression under the control of a multimerized GAL4 upstream activation sequence (UAS). The signal of the emitted luminescence was recorded by the FLIPR TETRA . This allowed for specific detection of antagonistic properties of compounds by measuring the ligand-induced inhibition of beclometasone-activated GR. The GAL4/UAS reporter was premixed with a vector that constitutively expressed Renilla luciferase, which served as an internal positive control for transfection efficiency. 
     The complete culture medium for the assay was:
         DMEM F-12 (1:1) MIXTURE (LONZA cat. No: BE04-687F/U1) 500 mL   5 mL of 100 mM Sodium Pyruvate (LONZA cat. No: BE12-115E)   25 mL of 7.5% Sodium Bicarbonate (LONZA cat. No BE17-613E)   6.5 mL of 1 M Hepes (LONZA cat. No: BE17-737E)   5 mL of 100× Penicillin/Streptomycin (LONZA cat. No DE17-602E)   50 mL of Fetal Bovine Serum (Euroclone cat. No ECS 0180L)   0.25 mL of 10 mg/mL Puromycin (InvivoGen cat.: ant-pr-1)   0.5 mL of 100 mg/mL Zeocin (InvivoGen cat.: ant-zn-1)       

     Cryo-preserved CHO-Gal4/GR cells were suspended in complete medium and 5000 cells/25 μl/well were seeded into the wells of 384-well polystyrene assay plates (Thermo Scientific, cat. #4332) and cultured at 37° C., 5% CO 2  and 95% humidity. After 24 hours growth medium was carefully removed and replaced by 20 μl Opti-MEM (GIBCO, cat. #31985062) as assay buffer. For testing compounds an 8-point half-log compound dilution curve was generated in 100% DMSO starting from a 2 mM stock and compounds were then diluted 1:50 in Opti-MEM. To test the compounds in the antagonist mode 10 μl of compounds were then added to the wells containing 20 μl Opti-MEM and incubated for 10 min. After this pre-incubation 10 μl of the reference agonist beclometasone (Sigma, cat. #Y0000351) at an EC50 of 2.5 nM were added resulting in a final assay concentration range from 10 μM to 0.003 μM in 0.5% DMSO in a total volume of 40 μl. Compounds were tested at 8 concentrations in quadruplicate data points. Cells were incubated for 6 hour with compounds and mifepristone as control compound (Sigma, cat. #M8046) at 37° C., 5% CO 2  and 95% humidity. Finally, cells were lysed with 20 μl of Triton/Luciferin solution and the signal of the emitted luminescence was recorded at the FLIPR TETRA  for 2 minutes. 
     The relative efficacy of a compound (% effect) was calculated based on the full effect of the antagonist mifepristone: 
       % effect=((compound−min)/(max−min))×−100
         [min=Opti-MEM only, max=mifepristone]       

     To calculate IC50, max, min and slope factor for each compound a concentration response curve was fitted by plotting % effect versus compound concentration using a 4 parameter logistic equation: 
         y=A +( B−A )/(1+((10 C )/×) D )
         [A=min y, B=max y, C=log IC 50 , D=slope]       

     In Table 7 below, the IC50 or EC50 ranges of the Examples are summarized which were observed in the agonistic assay or the antagonistic assay described above.
