FIELD OF INVENTION The present invention relates to SElective Glucocorticoid Receptor Agonistic Modulators (SEGRAMs) for use in the prevention or treatment of an inflammatory disorder in a subject in need thereof. In particular, the SEGRAMs of the present invention do not induce neither the direct transactivation nor the direct transrepression functions of the glucocorticoid receptor, and do not exert the debilitating effects of synthetic glucocorticoids (GC).

BACKGROUND OF INVENTION

Glucocorticoids (GCs) are primary stress hormones necessary for life that regulate numerous physiological processes in an effort to maintain homeostasis. They belong to the class of corticosteroids, which bind to their cognate receptor, the glucocorticoid receptor (GR).

GR, also known as NR3C1 (nuclear receptor subfamily 3, group C, member 1), is ubiquitous among almost every vertebrate, in almost every cell. It regulates the expression of genes controlling various important physiological processes, such as development, metabolism and immune response.

Structurally, GR is a modular protein composed of several domains:

an N-terminal transactivation domain (NTD, or "A/B domain");

a central DNA-binding domain (DBD, or "C domain"). This domain is the most conserved domain across the nuclear receptor superfamily and contains two zinc finger motifs that recognize and bind target DNA sequences, called glucocorticoid-responsive elements (GREs);

a flexible hinge region (or "D domain"); a C-terminal ligand binding domain (LBD, or "E domain"). This domain forms a hydrophobic pocket for binding GCs;

and a C-terminal domain (CTD or "F domain").

Upon binding of a GC to the GR LBD, the GR undergoes a conformational change resulting in the exposition of two nuclear localization signals located at the DBD/hinge region junction and within the LBD, respectively. GR is then rapidly translocated into the nucleus through nuclear pores, where it can exert one of the three transcriptional regulatory functions detailed hereafter and on Figure 1.

The first one, called "direct transactivation", is a consequence of binding of GC- associated GR directly to ds-acting positive GREs ((+)GREs), thereby activating the expression of target genes. The consensus (+)GRE sequence, GGAACANNNTGTTCT (with N being any of A, T, C or G) (SEQ ID NO: 1), is an imperfect palindrome comprising two 6-base pair half sites separated by 3 base pairs, hence termed "IR3" (for "inverted repeat 3"). The second function is "indirect tethered transrepression", which arises from the physical interaction of GC -bound GRs with the proinflammatory transcription factors AP-1 and NF-KB. Through binding to the Jun subunit of AP-1 and the p65 subunit of NF-κΒ, GR antagonizes their activity and interferes with the transcriptional activation function of these two proteins (Nissen and Yamamoto, 2000. Genes Dev. 14(18):2314-29; Yang- Yen et al., 1990. Cell. 62(6): 1205-15).

The third function, called "direct transrepression", is a consequence of GC-associated GR binding directly to the recently (2011) described negative GRE (nGRE) (Surjit et al., 2011. Cell. 145(2):224-41), which mediates the direct repression of specific genes. The consensus nGRE sequence, CTCC(N)o-2GGAGA (with N being any of A, T, C or G) (SEQ ID NO: 2), is also palindromic, but differs from the classic (+)GRE in sequence and spacer length (and is therefore named IR0, IR1 or IR2, as the case may be).

The anti-inflammatory properties of natural GCs were demonstrated more than 60 years ago (Carryer et al., 1950. J Allergy. 21(4):282-7). Since then, synthetic GCs derivatives have been widely used in treatments aimed at suppressing or alleviating acute and chronic inflammatory and allergic disorders in various diseases. However, GCs treatments are associated with a variety of serious debilitating side effects (Oray et al., 2016. Expert Opin Drug Saf. 15(4):457-65), such as type 2 diabetes, dyslipidemia, weight gain, cognitive impairment, gastritis, hepatic steatosis, osteoporosis, hypertension, ischemic heart disease, dermatoporosis, skin atrophy, cataract, glaucoma, mydriasis or suppression of cell-mediated immunity. Different side effects may occur in up to 90% of patients who take GCs for more than 60 days, regardless of the dose and route of administration. Some of these side effects may even occur in patients taking low (< 7.5 mg/day) dosages (Curtis et al., 2006. Arthritis Rheum. 55(3):420-6; Pereira et al., 2010. Clinics (Sao Paulo). 65(11): 1197-1205).

Before the discovery of the direct transrepression pathway in 2011, beneficial antiinflammatory effects of GCs had been ascribed to the indirect tethered transrepression pathway, while many of the undesirable side effects arising from GC treatments were thought to be related only to the direct transactivation pathway (Clark and Belvisi, 2012. Pharmacol Ther. 134(l):54-67) (Figure 1).

Intense efforts have therefore been made over the past decades to develop novel GR ligands, termed "dissociated" or "SElective" GR Agonistic Modulators (SEGRAMs), that would retain a transrepression profile, while having lost partially or, most ideally, entirely, their transactivation properties (Schacke et al., 2004. Proc Natl Acad Sci U S A. 101(l):227-32).

In this regard, a number of putative SEGRAMs have been developed, but few have made it to clinical trials. Such a ligand, RU24858, was found to exhibit such an expected dissociated profile in vitro (Vayssiere et al., 1997. Mol Endocrinol. 11(9): 1245-55). However, upon administration in vivo, pathophysiological studies failed to confirm this dissociation (Belvisi et al., 2001. J Immunol. 166(3): 1975-82).

Later, another synthetic non-steroidal ligand, namely Mapracorat (also named ZK245186 or BOL-303242-X), has been shown in vitro to act as an anti-inflammatory agent in corneal epithelial cells challenged with osmotic stress (Cavet et al., 2010. Mol Vis. 16: 1791-1800), and in vivo in experimental models of dry eye and postoperative inflammation (Shafiee et al., 2011. Invest Ophthalmol Vis Sci. 52(3): 1422-30), with an activity comparable to that of the synthetic "traditional" steroid dexamethasone, but reduced side effects in intraocular pressure and body weight. Mapracorat has also been the study product of several clinical trials between June 2009 and July 2013: a dose finding phase II clinical trial as an ointment for atopic dermatitis (Clinical trial numbers NCT00944632, NCT01228513, NCT01359787, NCT01407510, NCT01408511 and NCT01736462); and phase I, II and III clinical trials as an ophthalmic suspension for allergic conjunctivitis (Clinical trial number NCT01289431) and inflammation and pain following cataract surgery (Clinical trial numbers NCT00905450, NCT01230125, NCT01298752, NCT01591161, NCT01591655 and NCT01736462). However, as of October 2018, no study results of these trials are available and no marketing authorization has been granted, suggesting that Mapracorat might have revealed problems of efficacy and/or side effects.

As in 2011, the GC-bound GR- mediated direct transrepression function was also shown to be involved in undesirable side effects (Surjit et al., 2011. Cell. 145(2) :224-41), it appeared that targeting exclusively the indirect tethered transrepression pathway would be efficient in preventing side effects.

There remained thus a need for the development of bona fide SEGRAMs which cannot induce efficiently neither the direct transactivation nor the direct transrepression functions of GR, while still inducing its indirect tethered transrepression activity and antiinflammatory properties in vivo.

Interestingly, in the late 1990's, Schering AG, now Bayer HealthCare Pharmaceuticals, developed novel nonsteroidal compounds (see, e.g., US patent 6,245,804), claiming an anti-inflammatory activity dissociated from their metabolic effects, (see, e.g., US patent US6,323,199). By 2016, the Applicant discovered that among these compounds, one of them namely 5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-

(trifluoromethyl)pentylamino]isobenzofuran-l(3H)-one, hereafter named "CpdX", does not induce the transactivation and direct transrepression functions of the GR, while still inducing its indirect tethered transrepression activity (Hua et al., 2016. Proc Natl Acad Sci U S A. 113(5):E635-43). Herein, the Inventors show that, contrary to the putative SEGRAMs previously described in the art (such as Mapracorat), CpdX selectively induces the GR "indirect tethered transrepression activity", being thus a bona fide SEGRAM selectively exhibiting the GR indirect transrepression function, whereas Mapracorat exhibits all three GR functions. Most importantly, the Inventors demonstrate that, upon long-term administration to mice, CpdX and novel derivatives thereof are therapeutically as effective as the synthetic glucocorticoid Dexamethasone (Dex), while being devoid of the well-established debilitating side-effects of synthetic glucocorticoids.

DEFINITIONS

"Adrenal suppression", or "adrenal insufficiency" as used herein, refers to a condition in which the adrenal glands do not produce adequate amounts of Cortisol. Use of high- dose steroids for more than a week begins to produce suppression of the subject's adrenal glands because the exogenous glucocorticoids suppress hypothalamic corticotropin- releasing hormone (CRH) and pituitary adrenocorticotropic hormone (ACTH), as well as inhibit the syntheses of adrenal corticosterone synthesizing enzymes. With prolonged suppression, the adrenal glands atrophy and may take up to 9 months to recover full function after discontinuation of the exogenous glucocorticoid. During this recovery time, the subject is vulnerable to adrenal insufficiency during times of stress, such as illness, due to both adrenal atrophy and suppression of CRH and ACTH release.

"CpdX", as used herein, refers to the SElective Glucocorticoid Receptor Agonistic Modulator (SEGRAM) of Formula 1 :

(Formula 1)

or a pharmaceutically acceptable enantiomer, deuterated form, salt, solvate and/or prodrug thereof. "CpdX" corresponds to 5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(triflu oromethyl)pentylamino]- isobenzofuran-l(3H)-one (see Example 1, Figure 2A).

"Direct transactivation function of the glucocorticoid receptor (GR)" refers to the transcriptional activation of genes comprising a positive glucocorticoid response element ((+)GRE) (with SEQ ID NO: 1) bound by a glucocorticoid (GC)-associated GR in their promoter region.

"Direct transrepression function of the glucocorticoid receptor (GR)" refers to the transcriptional repression of genes comprising a negative glucocorticoid response element (nGRE) (with SEQ ID NO: 2) bound by a glucocorticoid (GC)-associated GR in their promoter region.

"Enhanced Th2 activity" means that a diseased subject has an increase (e.g. , at least 2- fold, 3-fold, 4-fold, 5-fold, 6-fold, 8-fold, 10-fold or more) in its Th2 activity, as compared to a healthy subject. An enhanced Th2 activity may be measured by an increase in the level of secreted cytokines and antibodies (e.g. , IL-Ι β, IL-4, IL-5, IL-6, IL- 10, IL- 13, TSLP, IgE and IgGl) according to methods known in the art.

"Enhanced Thl7 activity" means that a diseased subject has an increase (e.g. , at least 2- fold, 3-fold, 4-fold, 5-fold, 6-fold, 8-fold, 10-fold or more) in its Thl7 activity, as compared to a healthy subject. An enhanced Thl7 activity may be measured by an increase in the level of secreted cytokines (e.g. , IL- Ιβ, IL-6, IL- 17a, IL-17c, IL- 17f, IL- 21, IL-22, IL-23 and TGFP) according to methods known in the art.

"Enhanced Thl activity" means that a diseased subject has an increase (e.g. , at least 2- fold, 3-fold, 4-fold, 5-fold, 6-fold, 8-fold, 10-fold or more) in its Thl activity, as compared to a healthy subject. An enhanced Thl activity may be measured by an increase in the level of secreted cytokines and antibodies (e.g. , IL- Ιβ, IL-2, IL-3, IL-6, IL- 12, IL- 18, IL- 23, IFN-γ, TNFa and IgG2a) according to methods known in the art.

"Fatty liver", also referred to as "hepatic steatosis", as used herein, refers to a condition wherein large vacuoles of triglyceride fat accumulate in liver cells via the process of steatosis (i.e. , abnormal retention of lipids within a cell). This accumulation of fat may also be accompanied by a progressive inflammation of the liver (hepatitis), called steatohepatitis.

"Growth suppression" is an important and well-recognized adverse effect of steroidal anti-inflammatory drugs (SAID) therapy, in particular in children. The mechanism of growth suppression includes, without limitation, the effect of SAIDs on the essential components of anabolism and growth including bone metabolism, nitrogen retention, and the effect on collagen formation. SAID therapies also result in inhibition of growth hormone release and insulin-like growth factor- 1 (IGF- 1) bioavailability. In one embodiment, growth suppression upon SAID therapy affects the whole body, with a stunted physical growth. In one embodiment, growth suppression upon SAID therapy affects internal organs, and includes, but is not limited to, thymus, spleen, kidney, liver and adrenal gland.

"Hyperglycemia" is a condition in which an excessive amount of glucose circulates in the blood plasma, such as, e.g. , higher than 11.1 mmol of glucose per L of blood (200 mg of glucose per dL of blood). The American Diabetes Association guidelines classifies subjects in several subgroups, from slightly hyperglycemic (with a glucose level ranging from about 5.6 to about 7 mmol/L of blood, i.e., from about 100 to about 126 mg/dL of blood), to diabetic (with a glucose level above 7 mmol/L of blood, i.e., above 126 mg/dL of blood). The effect of SAIDs on glucose metabolism is dose-dependent and causes a mild increase in fasting blood glucose levels and a larger increase in postprandial blood glucose in patients without preexisting diabetes mellitus. SAID-induced hyperglycemia is multifactorial in origin and can be explained by the augmentation of hepatic gluconeogenesis, inhibition of glucose uptake in adipose tissue and/or alteration of receptor and post-receptor functions induced by SAIDs. Techniques to assess the development of hyperglycemia upon SAID therapy or upon administration of the SEGRAM of the present invention to a subject in need thereof are well-known from the skilled artisan, and include, without limitation, blood test with biochemical analysis and glucose test (including fasting blood sugar (FBS) test, fasting plasma glucose (FPG) test, glucose tolerance test, postprandial glucose (PG) test and random glucose test).

"Hyperinsulinemia" or "hyperinsulinism" as used herein, refers to a condition in which an excessive amount of insulin circulates in the blood plasma. Hyperinsulinemia is associated with hypertension, obesity, dyslipidemia and glucose intolerance (all collectively known as "metabolic syndrome"). "Indirect tethered transrepression function of the glucocorticoid receptor (GR)" refers to the transcriptional repression of genes comprising an AP-1 binding site (with a nucleic acid sequence ATGAGTCAT) and/or a NF-KB-binding site (with a nucleic acid sequence SEQ ID NO: 3 - GGGRNNYYCC, with R being any one of G or A, Y being any one of T or C, and N being any one of A, T, C or G) in their promoter region, bound by the Jun subunit of AP-1 and/or the p65 subunit of NF-κΒ respectively, themselves bound by a glucocorticoid (GC)-associated GR.

"Inflammatory disorder" refers to a pathological state resulting in inflammation, e.g., caused by influx of leukocytes and/or neutrophil chemo taxis. Inflammation may result from infection with pathogenic organisms and viruses, or from noninfectious means such as, e.g., immune response to foreign antigen, autoimmune responses, trauma or reperfusion following myocardial infarction or stroke. Thl, Th2 and TtJ7 cells are three subsets of T helper cells known to be involved in several inflammatory disorders. They differentiate from naive CD4 T cells (or ThO cells) depending on their cytokine environment: IFN-γ drives TtJ cell production while IL-10 and IL-4 inhibit TtJ cell production; conversely, IL-4 drives Th2 cell production and IFN-γ inhibits Th2 cells. As to Thl7 cells, their production is driven by TGF-β, IL-6, IL-21, IL-23 and IL-33.

"Osteoporosis" is a progressive disease characterized by low bone mass, microarchitecture deterioration of bone tissue, bone fragility, and a consequent increase in fracture risk. Secondary osteoporosis, as the consequence of systemic drug use such as SAIDs, is one of the most debilitating complications of glucocorticoid therapy, which has been recognized since 1940. The cumulative dose as well as the duration of SAID's exposure are the key determinants in the development of osteoporosis. Inhibition of osteoblast function is the main effect of SAIDs on bone metabolism leading to a decrease in bone formation. Bone loss starts promptly after the initiation of SAID therapy and is mainly taking place in the first six months of treatment. In addition to bone loss, SAID therapy can also result in changes in the architectural integrity of the bone. Techniques to assess the development of osteoporosis upon SAID therapy or upon administration of the SEGRAM of the present invention to a subject in need thereof are well-known from the skilled artisan, and include, without limitation, measuring the bone mineral density at baseline and comparing the baseline result to subsequent measurements during and after treatment. Techniques to prevent osteoporosis are also well-known from the skilled artisan and include, without limitation, administering to a patient in need thereof a supplementation in calcium and/or vitamin D, and appropriate physical activity.

"Prodrug", as used herein, refers to the pharmacologically acceptable derivatives of the SEGRAM of the invention, preferably of the compound of Formula 1 or a derivative thereof, such as esters whose in vivo biotransformation product is the active drug. Prodrugs are characterized by increased bio-availability and are readily metabolized into the active compounds in vivo. Suitable prodrugs for the purpose of the invention include carboxylic esters (in particular alkyl esters, aryl esters, acyloxyalkyl esters and dioxolene carboxylic esters) and ascorbic acid esters. "Reduced Th2 activity" means that a diseased subject has a decrease (e.g. , at least 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 8-fold, 10-fold or fewer) in its Th2 response, as compared to a healthy subject. A reduced Th2 activity may be measured by a decrease in the level of secreted cytokines and antibodies (e.g., IL-Ιβ, IL-3, IL-4, IL-5, IL-6, IL-10, IL-13, TSLP, IgE and IgGl) according to methods known in the art.

"Reduced Thl7 activity" means that a diseased subject has a decrease (e.g., at least 2- fold, 3-fold, 4-fold, 5-fold, 6-fold, 8-fold, 10-fold or fewer) in its Thl7 response, as compared to a healthy subject. A reduced Thl7 activity may be measured by a decrease in the level of secreted cytokines (e.g., IL-Ιβ, IL-6, IL-17a, IL-17c, IL-17f, IL-21, IL-22, IL-23 and TGFP) according to methods known in the art.

"Reduced Thl activity" means that a diseased subject has a decrease (e.g. , at least 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 8-fold, 10-fold or fewer) in its Thl response, as compared to a healthy subject. A reduced Thl activity may be measured by a decrease in the level of secreted cytokines and antibodies (e.g., IL-Ιβ, IL-2, IL-3, IL-6, IL-12, IL-18, IL-23, IFN-γ, TNFa and IgG2a) according to methods known in the art.

"Skin atrophy", also referred as to "steroid atrophy" or "corticosteroid-induced dermal atrophy", consists of a reduction in epidermal and/or dermal thickness, regression of the sebaceous glands, subcutaneous fat loss and/or muscle-layer atrophy. It results from the SAID-driven inhibition of mitotic activity of fibroblasts and/or of collagenase, leading to a decrease in collagen and glycosaminoglycan synthesis and a reduction in the diameter of the fibrils. Techniques to assess the development of skin atrophy upon SAID therapy or upon administration of the SEGRAM of the present invention to a subject in need thereof are well-known from the skilled artisan, and include, without limitation, visual control of the skin thinning and of the vascular prominence, use of calipers (including the Harpenden skinfold caliper), gravimetric, ultrasound, soft tissue X-ray, histiometric, electrical resistivity and transcriptional analysis of the Kindlin-1 (Ussar et al, 2008. PLoS Genet. 4(12):el000289) and REDDl (Britto et al., 2014. Am J Physiol Endocrinol Metab. 307(ll):E983-93; Baida et al., 2015. EMBO Mol Med. 7(l):42-58) genes.

"Solvate", as used herein, refers to a molecular complex comprising the SEGRAMs of the invention, preferably the compounds of Formula 1 or a derivative thereof and one or more pharmaceutically acceptable solvent molecules, e.g., ethanol. The term "hydrate" is employed when said solvent is water.

"Steroidal anti-inflammatory drugs (SAIDs) -associated side effects", as used herein, refers to side effects (also termed "debilitating effects") commonly observed in subjects undergoing a short-term, middle-term or long-term treatment with a steroidal antiinflammatory drugs (SAIDs).

"Th2-related inflammatory disorder" refers to any disease, disorder or condition, in which Th2 cells support, cause or mediate the disease, disorder or condition process or in which Th2 cells are involved in curing or alleviating the symptoms of the disease, disorder or condition, which may be represented by an enhanced or reduced Th2 activity.

"Thl7-related inflammatory disorder" refers to any disease, disorder or condition, in which Thl7 cells support, cause or mediate the disease, disorder or condition process or in which TtJ7 cells are involved in curing or alleviating the symptoms of the disease, disorder or condition, which may be represented by an enhanced or reduced TtJ7 activity. "Thl-related inflammatory disorder" refers to any disease, disorder or condition, in which Thl cells support, cause or mediate the disease, disorder or condition process or in which Thl cells are involved in curing or alleviating the symptoms of the disease, disorder or condition, which may be represented by an enhanced or reduced Thl activity.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 is a scheme showing the three transcriptional regulatory functions of the glucocorticoid receptor (GR) upon binding of a glucocorticoid (GC): on the left, the direct transactivation is the consequence of the binding of GC-associated GR directly to a cis- acting positive GRE ((+)GRE), thereby activating the expression of target genes. In the middle, the direct transrepression is the consequence of the binding of GC-associated GR directly to a cis-acting negative GRE (IR nGRE) which mediates the direct repression of target genes. On the right, the indirect tethered transrepression arises from the physical interaction of GC -bound GRs with the proinflammatory transcription factors AP- 1 and/or NF-KB, thereby antagonizing their activity.

Figure 2 comprises two schemes for the synthesis of either (A) [(R/S)-5-[4-(5-fluoro-2- methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentyla mino]isobenzofuran- l(3H)-one] [CpdX], or (C) [(R/S)-5-{4-[2-(methoxy-D3)-5-fluorophenyl]-2-hydroxy-4- methyl-2-(trifluoromethyl)pentylamino}isobenzofuran-l(3H)-on e] [CpdX-D3]; and two chromatograms showing the separation of the two enantiomers of either (B) [(R/S)-5-[4- (5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluorome thyl)pentylamino]-iso- benzofuran-l(3H)-one] [CpdX], or (D) [(R/S)-5-{4-[2-(methoxy-D3)-5-fluorophenyl]-2- hydroxy-4-methyl-2-(trifluoromethyl)pentylamino Jisobenzofuran- 1 (3H)-one] [CpdX- D3] through supercritical fluid chromatography (SFC) method.

EXAMPLES

The present invention is further illustrated by the following examples.

Example 1: Synthesis of CpdX and CpdX-D3 and separation of their enantiomers

"Racemic" CpdX synthesis and separation of its enantiomers CpdX(eA) and CpdX(eB)

The racemic mixture of the so-called compound CpdX { (R/S)-5-[4-(5-fluoro-2- methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentyla mino]isobenzofuran- l(3H)-one}, was synthesized as outlined in Figure 2A to 99.5 % purity, and its identity was confirmed by LCMS (MS+1=442.1), HPLC, HNMR and FNMR.

300 mg of a racemic mixture of CpdX were then run through a preparative supercritical fluid chromatography (SFC) AD column (250 mm * 30 mm * 5 μιη; mobile phase: Neu- MeOH; B : 20 -20 , 2.3 minutes). The collected fractions corresponding to the first elution peak (CpdX Peakl, Figure 2B) were then concentrated under reduced pressure at 30°C, lyophilized and further purified through a Phenomenex Synergi CI 8 column chromatography [150 mm * 25mm * 10 μιη; mobile phase: water (0.1 % TFA)-ACN; B : 50%-80%, 10 minutes]. The collected fractions were concentrated under reduced pressure at 30°C and lyophilized as a white solid (97.77 mg), the identity of which was confirmed by LCMS (MS+1=442.1) and SFC (retention time (RT) = 1.084 mins), and named as the "CpdX(eA)" enantiomer (97.6 % purity) (Table 1).

The collected fractions corresponding to the second elution peak (CpdX Peak2, Figure 2B) were similarly concentrated under reduced pressure at 30°C, lyophilized and further purified by Phenomenex Synergi C18 column chromatography [150 mm * 25 mm * 10 μιη); mobile phase: water (0.1 % TFA)-ACN; B : 51%-81%, 12 minutes]. The collected fractions were concentrated under reduced pressure at 30°C and lyophilized as a white solid (101.72 mg), the identity of which was confirmed by LCMS (MS+1=442.1) and SFC (RT = 1.147 minutes), and named as the "CpdX(eB)" enantiomer with a 98% purity (Table 1).

Further analysis will determine which of the two enantiomers CpdX(eA) and CpdX(eB) corresponds to the R and S forms, respectively.

Table 1

"Racemic" CpdX-D3 synthesis and separation of its enantiomers CpdX-D3(eA) and CpdX-D3(eB)

The racemic mixture of the so-called deuterated compound CpdX-D3, corresponding to the deuterated compound { (R/S)-5-{4-[2-(methoxy-D3)-5-fluorophenyl]-2-hydroxy-4- methyl-2-(trifluoromethyl)pentylamino}isobenzofuran-l(3H)-on e}, was synthesized as in Figure 2C with a 99.3 % purity and a 98.83 % deuterium content, and its identity was confirmed by LCMS (MS+1=445), HPLC, HNMR and FNMR.

84.4 mg of CpdX-D3 was then run through a preparative supercritical fluid chromatography (SFC) DAICEL CHIRALPAK AD-H column (250 mm * 30 mm * 5 μηι; mobile phase: 0.1% NH3H2O-MEOH; B%: 20%-20%, 2.3 minutes).

The collected fractions corresponding to the first elution peak (CpdX-D3 Peakl) were concentrated under reduced pressure at 30°C and lyophilized as a white solid (32.41 mg), the identity of which was confirmed by LCMS (MS+1=445) and SFC (RT = 1.082 minutes), and named as the enantiomer "CpdX-D3(eA)" with a 98.7 % purity. The collected fractions corresponding to the second elution peak (CpdX-D3 Peak2) were concentrated under reduced pressure at 30°C and lyophilized as a white solid (31.06 mg), the identity of which was confirmed by LCMS (MS+1=445) and SFC (RT = 1.149 minutes), and named as the "CpdX-D3(eB)" enantiomer with a 99.1% purity (Figure 2D). Further analysis will determine which of the two enantiomers CpdX-D3(eA) and CpdX- D3(eB) corresponds to the R and S forms, respectively.

Example 2: Unlike Mapracorat/ZK245186, CpdX. CpdX(eA). CpdX(eB). CpdX-D3. CpdX-D3(eA) and CpdX-D3(eB) are bona fide non-steroidal SElective GR Agonistic Modulators (SEGRAMs) (see Figure 3) Material and methods

Ears of Balb/C mice were treated overnight for 18 hours with 1 nmole/cm ² of either:

Ethanol [vehicle],

Dexamethasone [Dex],

Mapracorat,

- (R/S)-5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-

(trifluoromethyl)pentylamino]isobenzofuran- 1 (3H)-one [CpdX] ,

5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(triflu oromethyl)- pentylamino]isobenzofuran-l(3H)-one enantiomer A [CpdX(eA)], 5-[4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(triflu oromethyl)- pentylamino]isobenzofuran-l(3H)-one enantiomer B [CpdX(eB)],

- (R/S)-5-{4-[2-(methoxy-D3)-5-fluorophenyl]-2-hydroxy-4-methy l-2- (trifluoromethyl)pentylamino Jisobenzofuran- 1 (3H)-one [CpdX-D3] ,

- 5-{4-[2-(methoxy-D3)-5-fluorophenyl]-2-hydroxy-4-methyl-2-

(trifluoromethyl)pentylamino Jisobenzofuran- l(3H)-one enantiomer A [CpdX- D3(eA)], or

5-{4-[2-(methoxy-D3)-5-fluorophenyl]-2-hydroxy-4-methyl-2- (trifluoromethyl)pentylamino Jisobenzofuran- l(3H)-one enantiomer B [CpdX- D3(eB)].

RNA transcripts were then extracted from mouse ears and the transcripts of 4 genes were analyzed by q-RT-PCR:

(i) the directly GR-transactivated gene of the mTOR inhibitor REDD1,

(ii) the GR-directly transrepressed gene of keratin 5 (K5) and

(iii) the GR- indirectly "tethered" transrepressed genes of interleukin-ΐβ (IL-Ιβ) and interleukin-6 (IL-6), both being activated in presence of 12-0- tetradecanoylphorbol- 13-acetate (TPA) .

Results

Upon treatment with Dex or Mapracorat, in vivo transcriptional analyses have shown that Mapracorat, just as Dex, induces all three GR functions (direct transactivation, direct transrepression and indirect tethered transrepression, summarized in Figure 1), with a similar transactivation of the REDD1 gene (Figure 3A), a similar direct transrepression of the K5 gene (Figure 3B), and a similar indirect transrepression of the IL-Ιβ (Figure 3C) and IL-6 (Figure 3D) genes. On the contrary, GR selectively exhibits an indirect tethered transrepression activity upon in vivo administration of CpdX, with unchanged relative RNA expression levels for the REDD1 and K5 genes, as compared to control (Vehicle). Similar results were also obtained upon administration of either CpdX(eA) or CpdX(eB), or of their deuterated counterparts CpdX-D3, CpdX-D3(eA) and CpdX-D3(eB). Conclusion

Mapracorat is not a non-steroidal SElective GR Agonistic Modulator (SEGRAM), indicating that Mapracorat can exhibit - even if it could be to a lesser extent - similar side effects as those currently encountered upon a Dex treatment. In marked contrast, CpdX, as well as its two enantiomers CpdX(eA) and CpdX(eB), selectively exhibit the indirect tethered transrepression activity of GR, as expected for bona fide SEGRAMs. Most interestingly, the deuterated CpdX (CpdX-D3) and its two enantiomers [CpdX-D3(eA) and CpdX-D3(eB)] exhibit the same selectivity and antiinflammatory properties as their CpdX counterparts. Example 3: CpdX and CpdX-D3 are as efficient as Dexamethasone (Dex) at decreasing a TPA-induced irritant contact dermatitis-like Thl/Th2/Thl7 inflammation (see Figure 4)

Material and methods

Balb/C mouse ears were topically treated with TPA to induce an "irritant contact dermatitis-like inflammation".

Mice were treated for 4 days with TPA, then for 5 extra days (until D9) with either vehicle, TPA alone, TPA and Dex, TPA and CpdX or TPA and CpdX-D3.

At D10, RNA transcripts were extracted from mouse ear skin samples and the transcripts of CCL4, COX2, MMP13, IL-Ιβ, IL-6, TNF-a, TSLP, IL-22 and IL-23 were analyzed by q-RT-PCR. Ear skin was harvested, and histological (with H&E staining) and immunohistochemical (with anti-TSLP antibodies) analyses were carried out.

Results

The TPA-induced skin inflammation was significantly decreased by treatment with either Dex, CpdX or CpdX-D3. Transcript analyses using ear extracts from these mice indicated that CpdX and CpdX- D3 repressed, as efficiently as Dex, the TPA-induced transcription of pro-inflammatory genes (Figure 4).

Histological analysis of mouse ear skin showed that a TPA-induced ear skin inflammation was significantly decreased by treatment with either Dex, CpdX or CpdX-D3, as compared to the control (data not shown).

Immunochemistry analysis using a TSLP-specific antibody showed that the expression of TSLP in TPA-treated mouse epidermis was similarly strongly decreased by either a Dex, a CpdX or a CpdX-D3 treatment (data not shown). Conclusion

Taken altogether, these results demonstrate that CpdX and CpdX-D3 repress induced- skin inflammations as efficiently as Dex, indicating that both of them can be used in the treatment of skin inflammations, notably in the treatment of Thl/Th ₂ /Th 17 -related inflammatory disorders, such as contact dermatitis. Example 4: The topical administration of either Dex, CpdX or CpdX-D3, in a cream formulation or in ethanol (EtOH), results in a similar anti-inflammatory activity (see Figures 5 and 6)

Material and methods

Balb/C mouse ears were first topically treated with TPA for 3 days, which were followed by a three-day co-treatment without or with either Dex, CpdX or CpdX-D3 in ethanol (1 nmole/cm ² ) or in a cream (0,05% w/w) composed of vaseline, liquid paraffin, Emulgade ^® 1000 NI (BASF), propyl gallate, sodium edetate, sorbic acid and purified water.

RNA transcripts were extracted from mouse ear skin samples and the transcripts of IL- 1β, IL-6, COX2 and TNF-a were analyzed by q-RT-PCR. Ear skin was harvested and histological (with H&E staining) analyses were carried out. Results

Transcript analyses of ear extracts revealed a similar repression of the pro-inflammatory genes by Dex, CpdX or CpdX-D3 administered either in ethanol or in a cream formulation (Figure 5). Histological analysis of mouse ear skin confirmed similar anti-inflammatory effects (Figure 6).

Conclusion

CpdX, as well as CpdX-D3, administered either in ethanol or in a cream formulation, have the same anti-inflammatory efficiency in the treatment of a skin inflammation.

Example 5: CpdX, CpdX(eA), CpdX(eB), CpdX-D3. CpdX-D3(eA) and CpdX- D3(eB) are as efficient as Dexamethasone (Dex) at decreasing a calcipotriol (MC 903)-induced atopic dermatitis-like Th2 inflammation (see Figures 7 and 8)

Material and methods

To investigate the CpdX anti-inflammatory activity in vivo, Balb/C mouse ears were topically treated with calcipotriol (MC 903, a vitamin D ₃ analogue), in order to induce an atopic dermatitis (AD)-like inflammation (Li et al., 2006. Proc Natl Acad Sci U S A. 103(31): 11736-41).

Mice were treated for 14 days with MC 903, and then for 8 extra days (until D22) with either MC 903 alone (control), MC 903 and Dex, MC 903 and CpdX, MC 903 and CpdX(eA), MC 903 and CpdX(eB), MC 903 and CpdX-D3, MC 903 and CpdX-D3(eA) and MC 903 and CpdX-D3(eB).

At D23, RNA transcripts were extracted from mouse ear skin samples and the transcripts of 7 cytokines (MMP13, COX2, IL-Ιβ, IL-6, IL-10, IL-13 and TSLP) were analyzed by q-RT-PCR. Ear skin was harvested and histological (with H&E staining) and immunohistochemical (with anti-TSLP antibodies) analyses were carried out. Results

The MC 903-induced skin inflammation was significantly decreased by treatment with either Dex, CpdX or CpdX-D3.

RNA transcript analyses of ear extracts from these mice indicated that CpdX and CpdX- D3 repressed, as efficiently as Dex, the MC 903-induced transcription of a variety of proinflammatory genes (MMP13, COX2, IL-Ιβ, IL-6, IL-10, IL-13 and TSLP), including those of a T _h 2 inflammation (IL-10, IL-13 and TSLP) (Figure 7).

Histological analysis of mouse ear skin showed that a MC 903-induced ear skin inflammation was decreased by treatment with either Dex, CpdX or CpdX-D3, as compared to the control (Figure 8).

Immunohistochemistry analysis using a TSLP- specific antibody showed that the expression of the TSLP lymphokine in MC 903-treated mouse epidermis was similarly strongly decreased by either Dex, CpdX or CpdX-D3 (data not shown).

Similar results were also observed for a treatment with either CpdX(eA), CpdX(eB), CpdX-D3(eA) or CpdX-D3(eB) (Figures 7 and 8).

Conclusion

Taken altogether, these results demonstrate that a topical administration of CpdX, its deuterated form CpdX-D3 or any of their enantiomers [CpdX(eA), CpdX(eB), CpdX- D3(eA) and CpdX-D3(eB)] reduce as efficiently as Dex a skin inflammation, indicating that all of them are useful in the treatment of skin inflammations, notably in the treatment of Th2-related inflammatory disorders, such as atopic dermatitis. Example 6: CpdX, CpdX(eA), CpdX-D3 and CpdX-D3(eA). but not CpdX(eB) nor CpdX-D3(eB), are as efficient as Dexamethasone (Dex) at decreasing an asthma-like lung allergic Th2 inflammation (see Figures 9 to 13)

Material and methods Glucocorticoids have been (Pearlman et al., 1997. Ann Allergy Asthma Immunol. 78(4):356-62), and are still, widely used in asthma therapy. In order to investigate the possible CpdX anti-inflammatory activity in vivo, mice were sensitized and challenged with either ovalbumin (OVA) or house dust mite (HDM) to induce an asthma- like allergic lung inflammation. Ovalbumin sensitization and challenge

Mice were intraperitoneally sensitized with either 50 μg OVA together with alum or with alum alone on DO, D7 and D14. Mice were then subdivided into three groups, and on D19, D20 and D21, they were intranasally (i.n.) challenged with 10 μg OVA. The first and the second group received intranasally 0.5 mg/kg of body weight of Dex or CpdX respectively, while the third group served as a control.

On D22, the lung allergic inflammation was assessed for each mouse by examination of the broncho alveolar lavage fluid (BAL). The total BAL cells, eosinophils, neutrophils, macrophages and lymphocytes were counted. RNA transcripts were extracted from lung samples and RNA transcripts of IL-Ιβ, IL-6, IL-4, IL-5, IL-10, IL-13, Eotaxin, CCL4 and TNFa were analyzed by q-RT-PCR. Histological (with H&E staining) and immunohistochemical (with eosinophil-specific and neutrophil- specific antibodies) analyses of lung tissues were also carried out.

House dust mite (HDM) sensitization and challenge

Mice were intranasally sensitized with 1 μg HDM from DO to D4, and further intranasally sensitized with 10 μg HDM on D14 and D21. Mice were then subdivided into eight groups, and on D29, D30 and D31, each mouse was again intranasally challenged with 1 μg HDM. The first seven groups received respectively 0.5 mg/kg of body weight of Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB), while the eighth group served as a control.

On D32, the airway responsiveness was invasively determined using a computer- controlled small animal ventilator (FlexVent ^® system, SCIREQ Technologies). Mice were anesthetized with xylazine (15 mg/kg, i.p.), followed 15 minutes later by an i.p. injection of pentobarbital sodium (54 mg/kg). An 18-gauge metal needle was then inserted into the trachea, each mouse was connected to the FlexVent ^® ventilator and quasi-sinusoidally ventilated with a tidal volume of 10 mL/kg at a frequency of 150 breaths/minute and a positive end-expiratory pressure of 2 cm H ₂ 0, in order to achieve a mean lung volume close to spontaneous breathing. After baseline measurement, mice were challenged for 10 seconds with a saline aerosol and, at 4.5-minute intervals, with 50 mg/mL methacholine. Airway resistance and elastance were expressed as cmH ₂ 0.s/mL and cmH ₂ 0/mL respectively.

The lung allergic inflammation was assessed by examination of the bronchoalveolar lavage (BAL) fluid from each of these HDM-challenged mice. The total BAL cells, eosinophils, neutrophils, macrophages and lymphocytes were counted. RNA transcripts were extracted from lung samples. RNA transcripts of IL-Ιβ, IL-6, IL-4, IL-5, IL-13, Eotaxin, CCL4, IL-10 and TNFa were analyzed by q-RT-PCR. Lung tissues were harvested and histological (with H&E staining) and immunohistochemical analyses were also carried out (with eosinophil-specific and neutrophil- specific antibodies).

Results

Ovalbumin sensitization and challenge

Upon treatment with either Dex or CpdX, the total number of BAL cells, eosinophils, neutrophils and lymphocytes were all significantly decreased as compared to the control group. The number of macrophages was unchanged (Figure 9A).

Consistent with these results, transcriptional analyses of lung samples showed that the expressions of IL-Ιβ, IL-6 and of the Th2 pro-inflammatory genes IL-4, IL-5, IL-10 and IL-13, as well as of those of the eosinophil chemotactic chemokine Eotaxin, CCL4 and TNFa, were significantly and similarly decreased upon Dex or CpdX treatment (Figure 9B).

Histological analyses of lung paraffin sections demonstrated that the peribronchiolar (B) and perivascular (V) inflammatory cell infiltration was strongly decreased by either Dex or CpdX treatment (Figure 10).

Immunohistochemistry staining using eosinophil- specific and neutrophil- specific antibodies confirmed that both eosinophils and neutrophils were similarly decreased by either a Dex or a CpdX treatment (data not shown).

House dust mite (HDM) sensitization and challenge Upon treatment with either Dex, CpdX or CpdX-D3, the total number of BAL cells, eosinophils and lymphocytes were significantly decreased as compared to the control group. No significant change was observed in the number of neutrophils and macrophages (Figure 11A and B).

RNA transcriptional analyses of lung samples showed that the expressions of IL-Ιβ, IL- 6 and of Th2 pro-inflammatory genes (IL-4, IL-5, IL-13), as well as those of the eosinophil chemotactic chemokine Eotaxin and CCL4, were significantly and similarly decreased by Dex, CpdX or CpdX-D3 (Figure 11C and D), whereas those of IL-10 and TNFa were not affected (data not shown).

Histological analyses of lung paraffin sections demonstrated that the peribronchiolar and perivascular inflammatory cell infiltration was strongly decreased by either Dex, CpdX or CpdX-D3 treatment (Figure 12).

Immunohistochemistry staining using eosinophil- specific antibodies confirmed that eosinophils were decreased by either Dex, CpdX or CpdX-D3 treatment (data not shown). However, no significant change was observed using a neutrophil- specific antibody (data not shown).

Pulmonary functional tests (responses to methacholine analyzed by invasive measurements of airway resistance and elastance) demonstrated that Dex, CpdX or CpdX-D3 administration similarly reduced HDM-induced airway hyperresponsiveness (AHR) (Figure 13).

Surprisingly, a treatment with CpdX(eA) or CpdX-D3(eA), but not with CpdX(eB) nor CpdX-D3(eB), efficiently decreased the number of total BAL cells, eosinophils and lymphocytes (Figure 11A and B), as well as the expression of pro-inflammatory genes (Figure 11C and D). Histological analyses of lung paraffin sections revealed that the peribronchiolar and perivascular inflammatory cell infiltration was decreased by a CpdX(eA) or a CpdX-D3(eA) treatment, but not by a CpdX(eB) nor a CpdX-D3(eB) treatment (Figure 12). Accordingly, pulmonary functional tests showed that administration of CpdX(eA), but not CpdX(eB), reduced the HDM-induced airway hyperresponsiveness (AHR) (Figure 13).

Conclusion

Taken altogether, these results demonstrate that CpdX and CpdX-D3 repressed, as efficiently as Dex, allergen-induced lung inflammations, indicating their potential usefulness for the treatment of the Th2-related inflammatory disorders, such as asthma. Interestingly, CpdX(eA) and CpdX-D3(eA), but neither CpdX(eB) nor CpdX-D3(eB), did efficiently repress HDM-induced lung inflammation, indicating that only CpdX(eA) or CpdX-D3(eA) is the active enantiomer in the treatment of asthma.

Example 7: An Aldara-induced psoriasis-like Thl7 inflammation is reduced by a topical treatment with either Dexamethasone (Dex), CpdX or CpdX-D3 (see Figures 14 and 15)

Material and methods

Balb/C mouse ears were topically treated with Aldara ^® to induce a psoriasis-like skin inflammation (Vinter et al., 2015. Br J Dermatol. 172(2):345-53). Mice were treated for 9 days with Aldara ^® , including a co-topical treatment for the last 5 days with either ethanol (Vehicle), Dex, CpdX or CpdX-D3. At D10, RNA transcripts were extracted from mouse ears and IL-17a, IL-17c, IL-17f and IL-22 transcripts were analyzed by q-RT-PCR. Ear skin samples were also harvested for histological analyses (with H&E staining).

Results The Aldara ^® -induced psoriasis-like skin inflammation was significantly decreased by treatment with either Dex, CpdX or CpdX-D3. Interestingly, RNA transcript analyses of ear extracts indicated that the induced expression of the TtJ7 cytokines IL-17a, IL-17c, IL-17f and IL-22; but not of IL-23, were similarly reduced by a Dex, a CpdX or a CpdX- D3 treatment (Figure 14 and data not shown). Histological analyses by H&E staining confirmed these results and showed that either Dex, CpdX or CpdX-D3 could reduce an Aldara ^® -induced psoriasis-like skin inflammation (Figure 15).

Conclusion

These results demonstrate that in the mouse, CpdX or CpdX-D3 repressed, as efficiently as Dex, an Aldara-induced psoriasis-like skin inflammation, indicating that both CpdX and CpdX-D3 are as efficient as Dex in the treatment of this Thl7-related inflammatory skin disorder.

Example 8: CpdX, CpdX(eA). CpdX-D3 and CpdX-D3(eA). but not CpdX(eB). nor CpdX-D3(eB), are as efficient as Dexamethasone (Dex) at decreasing a collagen- induced arthritis (CIA) Thl7 inflammation (see Figures 16 to 18)

Material and methods

Mice were treated with collagen to induce a TtJ7 rheumatoid arthritis-like inflammation as described by Inglis et al. (2007. Arthritis Res Ther. 9(5):R113) and Geboes et al. (2009. Arthritis Rheum. 60(2):390-5). Male mice (DBA-1 strain) were subcutaneously-injected with 100 μg collagen per mouse on DO. The hind paw thickness at the ankle level was regularly measured with a caliper. When the ankle thickness had reached around 4 mm (TO, i.e., 30 to 50 days after the collagen injection on DO), mice were daily intraperitoneally- injected for 10 days (TO to T10) with either vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (1 mg/kg body weight diluted in NaCl 0,9%), and the hind paw thickness at the ankle level was daily measured with a caliper. Pictures of the hind paws were taken at days TO and T10 (before and after the treatment with either Vehicle, Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB)), in order to assess the course of swelling.

RNA transcripts were extracted from whole hind paws of collagen-untreated and collagen-treated mice at TO and T10. IL-Ιβ, IL-6, IL-17a, IL-17f and TNFa transcripts were analyzed by q-RT-PCR.

Results

The hind paw thickness showed an increase upon collagen injection, whereas Dex, CpdX and CpdX-D3 treatments resulted within 10 days into a rapid decrease of this thickness (Figures 16 and 17A). A similar decrease of the hind paw thickness was observed in mice treated with CpdX(eA) or CpdX-D3(eA), while in marked contrast no such decrease was observed upon a CpdX(eB) or a CpdX-D3(eB) treatment (Figure 17B and data not shown).

Most notably, the RNA transcripts of the pro-inflammatory genes which are expressed in the hind paws of mice which developed a CIA were similarly repressed by either a dexamethasone, a CpdX, a CpdX(eA), a CpdX-D3 or a CpdX-D3(eA) treatment, but not by a CpdX(eB), nor a CpdX-D3(eB) treatment (Figure 18).

Conclusion

These results demonstrate that both CpdX and CpdX-D3, as well as their enantiomers CpdX(eA), CpdX-D3(eA), but not their CpdX(eB) nor CpdX-D3(eB) enantiomers, are as efficient as Dex at decreasing a rheumatoid arthritis-like TtJ7 inflammatory. Example 9: CpdX, CpdX(eA), CpdX(eB). CpdX-D3. CpdX-D3(eA) and CpdX- D3(eB) are as efficient as Dexamethasone (Dex) at curing a Dextran Sodium Sulfate (DSS)-induced Thl7 ulcerative colitis (see Figures 19 and 20)

Material and methods To investigate the anti-inflammatory activity of CpdX and CpdX-D3 on a Thl7 ulcerative colitis, Balb/C mice were treated with 3% DSS in drinking water for 13 days, with or without an intraperitoneal administration of either Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (1 mg/kg of body weight) on Dl l, D12 and D13. At D14, RNA transcripts were extracted from mouse colons. IL-Ιβ, IL-6, IL-17a, IL-17f, TSLP and MMP13 transcripts were analyzed by q-RT-PCR. Colon samples were also harvested for histological analyses (with H&E staining).

Results

Histological analyses (H&E stained paraffin sections) (Figure 19 and data not shown) showed dramatic damages in DSS-treated mouse colon as compared to control mice (no DSS treatment): the regular colonic villus/crypt structure was highly disorganized or absent in DSS-treated mice. In addition, ulcerations (arrow head), as well as cell infiltrations into the colonic mucosal (solid arrows) and submucosal (dotted arrows) layers were also observed. Most notably, in mice treated for 3 days with either Dex, CpdX, CpdX-D3 or their two enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) and CpdX-D3(eB), the colonic villus/crypt structure was almost reestablished and both the mucosal and the submucosal cell infiltration were significantly decreased.

Transcriptional analyses showed (Figure 20) that the pro-inflammatory genes which were overexpressed in DSS-induced ulcerative colitis were similarly repressed by either Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB). Conclusion

Taken altogether, our results demonstrate that CpdX, CpdX-D3 and their enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) and CpdX-D3(eB) are as efficient as Dex for the treatment of a Thl7-related inflammatory disorder, such as ulcerative colitis. Example 10: CpdX, CpdX(eA). CpdX(eB). CpdX-D3. CpdX-D3(eA) or CpdX- D3(eB) alleviate as efficiently as Dexamethasone (Dex) an ovalbumin (OVA)- induced allergic conjunctivitis (see Figure 21)

Material and methods

To investigate the anti-inflammatory effect of CpdX or CpdX-D3 on an allergic conjunctivitis, Balb/C mice were intraperitoneally sensitized with 50 μg OVA with alum on both days Dl and D8, and then challenged from D15 to D21 with 250 μg OVA in 5 μΐ _^ of sterilized vehicle (0.9% NaCl), which were directly instilled onto the conjunctival sac. From D22 to D24, mice were divided into several groups, and received instillations with either OVA alone, OVA together with 0.1% of either Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB).

The clinical appearance of mouse eyes was evaluated 20 minutes after the last instillation on D24. Clinical signs (conjunctival hyperemia, lid edema and tearing) were scored to evaluate the occurrence and severity of conjunctivitis as described by Gimenes et al. (2015. Experimental Eye Research 134:24-32). Parameters were graded on a scale ranging from 0 to 3, (0 = absence, 1 = mild, 2 = moderate, and 3 = severe symptoms), each animal receiving a total clinical score ranging from 0 to 9. The data were expressed as mean + SEM with at least four mice per treatment.

Results

20 minutes after the last OVA challenge, eyes from all OVA-treated mice presented obvious clinical signs of allergic conjunctivitis as compared to control mice (Vehicle) (Figure 21). These signs were considerably reduced by Dex treatment, as well as by either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) treatment (Figure 21).

Conclusion

These results demonstrate that CpdX, CpdX-D3 and their enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) and CpdX-D3(eB) reduce, as efficiently as Dex, an ovalbumin (OVA)-induced allergic conjunctivitis.

Example 11: In marked contrast to Dexamethasone (Dex), a topical treatment with either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) does not induce a skin epidermis atrophy (see Figures 22 to 24) Material and methods

Skin atrophy is a severe limitation to topical treatments with glucocorticoids (Schoepe et al., 2006. Exp Dermatol. 15(6):406-20).

To investigate whether, similarly to Dex, a topical administration of CpdX could result in a skin atrophy, Balb/C mice were shaved on the dorsal skin. Ethanol (vehicle), Dex, CpdX or either one of its two enantiomers CpdX(eA) or CpdX(eB), as well as the deuterated form CpdX-D3 or either one of its two enantiomers CpdX-D3(eA) or CpdX- D3(eB), were topically applied onto the dorsal skin for 8 days.

Upon completion of the treatments, RNA transcripts were extracted from dorsal skin samples and the transcripts of Kindlin- 1 and REDD 1 genes were analyzed by q-RT-PCR. Histological and morphometric analyses of the dorsal skin were also performed.

Results

It has been reported that a loss of the Kindlin- 1 protein results in an epidermal skin atrophy (Ussar et al., 2008. PLoS Genet. 4(12):el000289), while, in marked contrast, the loss of the Reddl protein prevents a GC-induced skin atrophy (Britto et al., 2014. Am J Physiol Endocrinol Metab. 307(ll):E983-93; Baida et al., 2015. EMBO Mol Med. 7(l):42-58). Most interestingly, transcriptional analyses from dorsal skin samples clearly indicated that the transcription of the Kindlin-1 gene (which contains a nGRE) is strongly decreased by a Dex topical treatment, but not by either of a CpdX, CpdX(eA), CpdX(eB), CpdX- D3, CpdX-D3(eA) or CpdX-D3(eB) treatment (Figure 22A). Conversely, the transcription of the REDD1 gene (which contains a +GRE) is significantly increased by a Dex, but not by a CpdX, a CpdX(eA), a CpdX(eB), a CpdX-D3, a CpdX-D3(eA) nor a CpdX-D3(eB) treatment (Figure 22B).

Consistent with RNA transcripts analyses, morphometric analyses showed that the epidermal thickness decreases by ~ 65 % upon an eight-day Dex treatment. In contrast, the epidermal thickness is not significantly decreased by a CpdX, a CpdX(eA), a CpdX(eB), a CpdX-D3, a CpdX-D3(eA) or a CpdX-D3(eB) treatment (Figure 23). These data are fully consistent with the histological analysis demonstrating that an application of Dex, in marked contrast with that of CpdX or its deuterated form CpdX-D3 or any of their enantiomers, severely induces a skin atrophy (Figure 24). Conclusion

Our results clearly demonstrate that, in marked contrast with a Dex topical treatment, a topical treatment with either CpdX, or its deuterated form CpdX-D3, or any of their enantiomers [CpdX(eA), CpdX(eB), CpdX-D3(eA) and CpdX-D3(eB)], does not result in an epidermal skin atrophy, indicating CpdX and CpdX-D3 can be safely used in skin treatments.

Example 12: A three-month treatment with either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) does not affect the cortical nor the trabecular bone formation, in contrast to a Dexamethasone (Dex) treatment (see Figures 25 and 26) Material and methods

B6 male mice (8-week-old) were daily subjected for three months to either a subcutaneous injection of vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX- D3(eA) or CpdX-D3(eB) (1 mg/kg body weight, diluted in NaCl 0,9%). From each animal included in the experiments, one femur and the ipsilateral tibia were dissected and preserved in 70% ethanol for further bone micro structure analysis by micro- CT. The FX Quantum micro-CT scanner (Perkin Elmer) was used to perform measurements at the distal femur and midshaft tibia. All scans were performed with an isotropic voxel size of 10 μιη, 160 μΑ tube current and 90 kV tube voltage.

Morphological 3D measurements were performed using the CTAn software (Bruker). Cortical bone parameters, which were measured in the tibia midshaft, included measures of the bone volume fraction as compared to the total volume, cortical thickness, total area, bone area and marrow area. The region of interest was selected from below the distal tibial crest and continued for 20 slices toward the proximal end of the tibia. Trabecular bone parameters were measured in the distal metaphysis of the femurs and included bone volume fraction, trabecular thickness, trabecular number and trabecular spacing. The region of interest was selected from below the distal growth plate where the epiphyseal cap structure completely disappeared and continued for 100 slices toward the proximal end of the femur.

The statistical significance as compared to vehicle treatment was calculated through oneway ANOVA test followed by Dunn's multiple comparison test, * p<0,05; ** p<0,01; *** p<0,001; **** p<0,0001.

Results Osteoporosis is a common undesirable side effect of a long-term glucocorticoid clinical treatment (Canalis, 2003. Curr Opin Rheumatol. 15(4):454-7). As expected, after a three- month Dex treatment, osteoporosis-like phenotypes were observed in the mouse tibia cortical bone: the bone volume was significantly decreased as compared to the total volume (Figure 25A), the cortical thickness was drastically decreased (Figure 25B) and the bone area, but not the marrow area, was also reduced (Figures 25D and E). Surprisingly, but in agreement with a previous report (Grahnemo et ah, 2015. J Endocrinol. 224(1):97-108), a Dex-treatment increased the mouse trabecular bone volume due to an increase in the number of trabecula and a decrease of the trabecular spacing, with no change in the trabecular thickness (data not shown). Importantly, in marked contrast to Dex treatment, this three-month administration of CpdX or CpdX-D3, as well as of either of their enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) or CpdX-D3(eB), did not affect the bone formation in cortical and trabecular bones (Figure 25 and data not shown). The expression of the WNT16 gene has been reported to affect the bone mineral density, the cortical bone thickness, the bone strength, and the risk of osteoporotic fracture (Zheng et ah, 2012. PLoS Genet. Jul; 8(7): el002745). Transcriptional analyses from mouse tibia samples demonstrated that the transcription of the WNT16 gene was decreased by 50% with a Dex treatment, but not with either a CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) treatment (Figure 26).

Conclusion

These results indicate that CpdX, CpdX-D3 and any of their enantiomers [CpdX(eA), CpdX(eB), CpdX-D3(eA) or CpdX-D3(eB)] could be safely used for clinical treatments of inflammatory diseases, unlike Dex, they do not affect bone formation. Example 13: In contrast to Dexamethasone (Dex), a long-term treatment with either CpdX or CpdX-D3 does not induce a loss of body weight, nor a change in body composition (see Figure 27)

Material and methods

B6 male mice (8-week-old) were daily subjected for three months to a subcutaneous injection of either vehicle (NaCl 0,9%), Dex, CpdX or CpdX-D3 (1 mg/kg body weight, diluted in vehicle. A pDEXA machine was used to determine the lean mass and fat mass. The statistical significance was calculated through Krustal-Walis test followed by a Dunn's multiple comparison test, * p<0,05; ** p<0,01; *** p<0,001.

Results 8-week-old mice which, when treated for 3 months with either vehicle, CpdX or CpdX- D3 exhibited a similar increase of body weight (Figure 27A), as well as a commensurate increase in fat mass (Figure 27B) and lean percentage (Figure 27C). In contrast, mice treated with Dex exhibited a net loss in total body weight (Figure 27A), together with a disproportional increase in fat (Figure 27B) and a decrease of lean mass (Figure 27C).

Conclusion

These results indicate that a long-term administration of CpdX or CpdX-D3, in contrast to that of Dex, does not result in a loss of body weight, nor in an increase of fat mass and a decrease of lean mass.

Example 14: Upon a three-month in vivo administration, mice treated with either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) do not exhibit the undesirable tissue-specific "toxic" side-effects observed in mice treated with Dexamethasone (Dex) (see Figure 28)

Material and methods

B6 male mice (8-week-old) were daily subjected for three months to a subcutaneous injection of either vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (1 mg/kg body weight, diluted in vehicle). Following these treatments, four organs (thymus, spleen, adrenal gland and kidney) were harvested and weighted.

Results

Glucocorticoids are well known to induce a drastic thymus apoptosis (Cohen, 1992. Semin Immunol. 4(6):363-9). Accordingly, after a three-month treatment, no thymus was found in sixteen out of nineteen mice treated with Dex. In marked contrast, a treatment with either CpdX, its deuterated form CpdX-D3, or their enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) or CpdX-D3(eB) did not result in any significant thymus apoptosis (Figure 28A).

The spleen weight was decreased by more than 50 % in Dex-treated mice, whereas it was not decreased in CpdX-, CpdX(eA)-, CpdX(eB)-, CpdX-D3-, CpdX-D3(eA)- or CpdX- D3(eB)-treated mice (Figure 28B). A weak, but significant loss of the kidney weight was also selectively observed in mice treated with Dex (Figure 28D). Interestingly, the weight of the adrenal gland, in which corticosterone synthesis takes place, was decreased by a Dex treatment, whereas it was increased by a treatment with either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (Figure 28C). Conclusion

Upon a long-term treatment in vivo, and in marked contrast with the administration of the synthetic glucocorticoid Dexamethasone, the administration of CpdX or its deuterated form CpdX-D3, or any of their enantiomers [CpdX(eA), CpdX(eB), CpdX-D3(eA) and CpdX-D3(eB)], is not toxic, most notably for the thymus, the spleen and the adrenal gland.

Example 15: A long-term daily subcutaneous injection of Dexamethasone (Dex) inhibits corticosterone synthesis which, in marked contrast, is increased by a similar treatment with either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (see Figures 29 and 30) Material and methods

B6 male mice (8-week-old) were daily subjected for three months to either a subcutaneous injection of vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX- D3(eA) or CpdX-D3(eB) (1 mg/kg body weight, diluted in vehicle).

Following this long-term treatment, blood was collected at 10 a.m. and 6 p.m. by retro- orbital puncture in lithium-heparin coated vials, and the plasmatic level of corticosterone was determined. Adrenal glands were harvested and weighted. RNA transcripts were extracted and transcripts of the Cypl la, Cypl lbl, Cypl lb2 and HSD3P genes were analyzed by q-RT-PCR. Histological analyses of the adrenal glands were also carried out. Results

Corticosterone is synthesized in the fasciculata zone of the cortex layer of the adrenal gland. Upon a three-month treatment with Dex, the cortex layers (see double-headed arrow in left panels), most notably the fasciculata zone (see bold double-headed arrow in right panels) of the adrenal glands were drastically decreased (Figure 29), whereas they were markedly increased by administration of CpdX or its deuterated form CpdX-D3, or either of their enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) or CpdX-D3(eB) (Figure 29 and data not shown).

Transcriptional analyses from mouse adrenal glands samples demonstrated that the transcripts of Cypl la, Cypl lbl and HSD3P genes, which are involved in the corticosterone synthesis pathway, were inhibited by Dex treatment, while increased by CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) treatments (Figure 30A).

As compared to control mice (Vehicle), Dex-treated mice exhibited a much lower corticosterone levels at both 10 a.m. and 6 p.m. whereas, in marked contrast, CpdX-, CpdX(eA)-, CpdX(eB)-, CpdX-D3-, CpdX-D3(eA)- and CpdX-D3(eB)-treated mice exhibited a much higher corticosterone level at 10 a.m. (Figure 30B).

Interestingly, transcriptional analyses from mouse adrenal glands samples also showed that the transcript of the Cypl lb2 gene, which is involved in the aldosterone synthesis pathway, is inhibited by Dex treatment, but not by CpdX, CpdX(eA), CpdX(eB), CpdX- D3, CpdX-D3(eA) or CpdX-D3(eB) treatment (Figure 30A). In agreement with this result, histological analyses revealed that the glomerulosa zone (outermost zone of the cortex layer, see the small empty double-headed arrows in the right panels of Figure 29), which produces aldosterone, was drastically decreased by Dex treatment, but not by either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) treatment (Figure 29 and data not shown). Conclusion

Most interestingly, these data indicate that the beneficial anti-inflammatory effects of CpdX and of its deuterated form CpdX-D3 [as well as any of their enantiomers CpdX(eA), CpdX(eB), CpdX-D3(eA) and CpdX-D3(eB)] which occur through repression of pro -inflammatory genes, result from both (i) the direct binding of CpdX or CpdX-D3 to the GR, which activates its tethered indirect transrepression function, and (ii) a further activation of this indirect transrepression function due to a CpdX- or CpdX- D3-induced increase of the blood corticosterone level, most notably during the rest period. Example 16: In marked contrast with a three-month administration of Dexamethasone (Dex), a three-month in vivo administration of either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) does not induce hyperglycemia (see Figure 31)

Material and methods Upon a long-term glucocorticoid administration, hyperglycemia is a common undesirable side effect (Clore & Thurby-Hay, 2009. Endocr Pract. 15(5):469-74).

B6 male mice (8-week-old) were daily subjected for three months to a subcutaneous injection of either vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (1 mg/kg body weight, diluted in vehicle). Mice were over-night-fasted. Mouse blood glucose concentration was measured before (To) and during two hours (T ₁₂ o) after glucose i.p. injection (2 mg/kg body weight).

Results

After a three-month treatment, the blood glucose level in Dex-treated mice was significantly higher than in mice treated with either saline (vehicle), CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (Figure 31A).

An intraperitoneal glucose tolerance test (IPGTT) showed that, upon glucose injection, a significant higher blood glucose level was observed during a two-hour period in Dex- treated mice, whereas there was no significant difference between these levels in control, CpdX-, CpdX(eA)-, CpdX(eB)-, CpdX-D3-, CpdX-D3(eA)- or CpdX-D3(eB)-treated mice (Figure 31B).

Conclusion These above results indicate that, in contrast to Dex, a treatment with CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) does not significantly affect the control of the blood glucose level.

Example 17: A three-month in vivo administration of either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB), unlike that of Dexamethasone (Dex), does not induce an insulin-resistance (see Figures 31 and 32)

Material and methods

A chronic exposure of humans to glucocorticoids (GC) is well known to result in whole- body insulin-resistance (Geer et ah, 2014. Endocrinol Metab Clin North Am. 43(1):75- 102). B6 male mice (8-week-old) were subjected daily for three months to a subcutaneous injection of either vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (1 mg/kg body weight, diluted in vehicle). After three months, the blood was collected at 10 a.m. by retro-orbital puncture in lithium-heparin coated vials, and the plasmatic level of insulin was determined. For the intraperitoneal insulin tolerance test (IPITT), mice were fasted for 6 hours before test. The blood glucose concentration was measured both before (To) and during a one- hour period after insulin i.p. injection (0,75 U/kg body weight).

Following this three-month treatment, liver samples were harvested and lysed in the RIPA buffer (20 mM Tris pH 8, 150 mM NaCl, 10% glycerol, 1% NP-40 and 2 mM EDTA). Antibodies from Cell Signaling were used to assess by Western-Blotting the relative level of p-IRSl (S318), IRS-1, p-AKT (S473) and AKT. Results

After a three-month treatment, the blood insulin level revealed a hyperinsulinemia in Dex-treated mice, but not in mice treated with either saline (vehicle), CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (Figure 32A). As an hyperglycemia was observed in Dex-treated mice (Figure 31A) and an IPITT test disclosed a significant impaired response to insulin in these mice (Figure 32B), they may reveal an insulin resistance. In keeping with this suggestion, western-blot analyses from liver extracts showed in Dex-treated mice, but not in vehicle-, CpdX- or CpdX-D3-treated mice, a decrease in phosphorylated insulin receptor substrate 1 (p-IRSl S318) (Figure 32C). As expected the phosphorylation of insulin- stimulated protein kinase B (p-AKT S473) was also decreased in Dex-treated mice (Figure 32C).

Conclusion

These results indicate that, in contrast to Dexamethasone, a treatment with CpdX, its deuterated form CpdX-D3, or any of their enantiomers [CpdX(eA), CpdX(eB), CpdX- D3(eA) or CpdX-D3(eB)], does not induce an insulin resistance.

Example 18: In marked contrast to Dexamethasone (Dex), a three-month in vivo administration of either CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) does not induce a fatty liver (see Figures 33 to 35)

Material and methods B6 male mice (8-week-old) were daily subjected for three months to a subcutaneous injection of either vehicle (NaCl 0,9%), Dex, CpdX, CpdX(eA), CpdX(eB), CpdX-D3, CpdX-D3(eA) or CpdX-D3(eB) (1 mg/kg body weight, diluted in vehicle). Following this treatment, blood was collected at 10 a.m. by retro-orbital puncture in lithium-heparin coated vials. The plasmatic levels of total cholesterol and bile acids were determined. Liver samples were harvested. Lipid deposition in the liver was revealed by 5% Red oil staining of frozen sections. RNA transcripts were extracted from liver samples and the transcripts of fatty acid synthase (FASN) and Stearoyl-CoA desaturase 1 (SCDl) genes were analyzed by q-RT-PCR.

Results

Upon a three-month treatment, there was a marked lipid deposition in the liver of mice subjected to a daily subcutaneously administration of Dex, which was not observed in mice treated with either CpdX or CpdX-D3, their enantiomers or Vehicle (Figure 33). Accordingly, an increase in transcripts of fatty acid synthase (FASN) and Stearoyl-CoA desaturase 1 (SCDl), which are critically involved in liver lipogenesis, was observed in liver of Dex-treated mice, but not of vehicle-, CpdX-, CpdX(eA)-, CpdX(eB)-, CpdX- D3-, CpdX-D3(eA)- or CpdX-D3(eB)-treated mice (Figure 34).

Hypercholesterolemia is a main cause of non-alcoholic fatty liver diseases (NAFLDs) (Kim et ah, 2014. PLoS One. 9(6):e97841). Cholesterol is converted in liver into bile acids. Accordingly, a high level of bile acids was also observed in patients exhibiting fatty liver diseases (Aranha et ah, 2008. Eur J Gastroenterol Hepatol. 20(6):519-25). As expected, Dex-treated, but not CpdX-, CpdX(eA)-, CpdX(eB)-, CpdX-D3-, CpdX- D3(eA)- or CpdX-D3(eB)-treated mice, exhibited a clear increase in blood cholesterol and bile acids' levels (Figure 35).

Conclusion

A three-month in vivo treatment with CpdX or its deuterated form CpdX-D3, or either of their enantiomers [CpdX(eA), CpdX(eB), CpdX-D3(eA) or CpdX-D3(eB)], does not induce a fatty liver disease, in marked contrast with a similar treatment with Dex.
