AHR AGONISTSFIELD OF THE INVENTION

[0001] The present disclosure relates to novel AHR agonist compounds, to pharmaceutical compositions comprising the compounds, and to methods of using ths compounds to treat certain immune-mediated diseases.BACKGROUND OF THE INVENTION

[0002] The present disclosure is m the field of treatment of certain immune-mediated diseases (IMD), in particular psoriasis and atopic dermatitis, via the activation of the aryl hydrocarbon receptor (AHR).

[0003] IMDs encompass a broad range of chronic and debilitating inflammatory conditions that affect approximately 4% of the population worldwide. In view of the limited efficacy of currently available treatments, and few small molecule treatment options, there is significant unmet need for alternative, potent, selective, and safer drugs for the treatment of IMDs.

[0004] AHR is a transcription factor which regulates many aspects of immunological function, most notably the suppression of adaptive immune responses (Ehrlich et al., Curr. Opin. Toxicol., 2, 72-78 (2017)). Prototypical AHR agonists include halogenated dibenzodioxins, such as 2,3,7,8-tetrachlorodibenzodioxin (TCDD), tryptophan metabolites, such as L-kynurenine, bilirubin, and PGE2. Results from studies on AHR agonists, especially TCDD, suggest that immune suppression occurs as the result of AHR-induced expression of regulatory T ceils (Tregs), TH17 cells, and dendritic ceils (DCs) (Rothhammer et al., Nat. Rev, Immunol., 19, 184-197 (2019)). TCDD has been shown to be effective in the prevention of several murine models of IMD, including type- 1 diabetes (Kerkvliet et al., Immunotherapy, 1, 539-547 (2009)), autoimmune encephalomyelitis (Quintana et al.. Nature, 453, 65-71 , (2008)), autoimmune uveoretmitis (Zhang et al., Invest. Opthalmol. Vis. Sci., 51 , 2109-21 17 (2010)), inflammatory bowel disease (Takamura et al., Immunol. Cell. Biol., 88, 685-689 (2010), Benson et al., Toxicol. Sci., 120, 68-78 (201 1), Singh et al., PLoS One, 6(8), e23522. (2011)), as well asseveral models of transplant tolerance (Pauly at al., Toxicol. Environ. Chem., 94, 1175- 1 187 (2012)) and allergic diseases (Schulz et al,, Toxicol. Set., 123, 491-500 (201 1), Li et al, PLoS One, 11 , e0150551 (2016), Luebke et al„ Toxicol. Sci., 62, 71-79 (2001 )).

[0005] AHR also regulates the expression of CYP1 Al, CYPIA2, and CYP1B1, which catalyze the metabolism of polycyclic aromatic hydrocarbon (PAH) and other aromatic compounds (e.g., estrogen). While in some cases (for example in the case of benzo [a]pyrene) this metabolism results in the formation of reactive species, CYP induction is also believed to be critical for the detoxification and metabolic clearance of PAHs, which reduces the probability of bioactivation, and DNA adduct formation. Several marketed drugs were found to activate AHR (thus upregulating CYP 1 A l, CYP1A2, and CYP1B1) after their FDA approval, yet their long-term use is not associated with dioxin-like toxicities (Ehrlich et al., Curr. Opin. Toxicol., 2, 72-78 (2017)). As such, CYP induction is no longer viewed as a barrier to the adoption of AHR agonists in therapy (Ehrlich et al., Curr. Opin. Toxicol., 2, 72-78 (2017)).

[0006] The bacterial stilbenoid DMVT-505 (VTAMA® (tapinarof)) 1% cream, an aryl hydrocarbon receptor agonist, indicated for the topical treatment of plaque psoriasis in adults, has been approved by the U.S. Food and Drug Administration (FDA). Despite this, there remains a need for alternative novel, oral, selective, and potent AHR agonists for the treatment of IMDs. The present disclosure provides certain compounds that are agonists of AHR and potential treatment options.SUMMARY OF THE INVENTION

[0153] As used herein, the term “aryl”, used alone or as part of a larger moiety, refers to an aromatic hydrocarbon group, having 6, 10, or 14 re-electrons shared in a cyclic array. Aryl can be monocyclic (having one ring), bicyclic (having two rings), or polycyclic (having two or more rings). Exemplary' aryl includes phenyl, naphthyl, anthracenyl, and phenanthrenyl.

[0154] As used herein, the terms “aromatic group” and “aromatic unit”, refers to aryl and heteroaryl (as defined below) groups.

[0155] As used herein, the term “monocycle”, refers to a ring system of one cycle, where each ring atom of the cycle can be a carbon or a heteroatom . In other words, the monocycle can be a carbocycle or a heterocycle (each defined below).

[0156] As used herein, the term “cycloalkyl” refers to a saturated ring system containing at least three carbon atoms. Cycloalkyl can be monocyclic (having one ring), bicyclic (having two rings), or polycyclic (having two or more rings). Exemplary monocyclic cycloalkyl rings include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and cycloheptyl.

[0157] As used herein, the term “carbocycle” refers to a saturated or unsaturated ring system containing only carbons. Carbocycles include cycloalkyls and aryls and partially saturated rings.

[0158] As used herein, the term “halo” refers to halogen as a substituent, and specifically chloro, fluoro, bromo, or iodo.

[0159] As used herein, the term “heterocyclic” and “heterocycle” refers to an optionally substituted, saturated ring system containing at least two carbon atoms and at least one heteroatom. Exemplary heteroatoms are oxygen, nitrogen, and sulfur. Exemplary' heterocyclic rings (or heterocycles) include oxirane, aziridine, oxetane, oxolane, pyrrolidine, piperidine, and morpholine. Heterocycles can be monocycles (having one ring), bicycles (having two rings), or polycycles (having two or more rings) that may be, for example, fused with each other.

[0160] As used herein, the term “heteroaryl” refers to groups having 5 to 10 ring atoms, preferably 5, 6, 9, or 10 ring atoms, having 6, 10, or 14 re-electrons shared in a cyclic array, and having, in addition to carbon atoms, from one to five heteroatoms. Tire term “heteroatom” refers to nitrogen, oxygen, or sulfur, and includes any oxidized form ofnitrogen or sulfur, and any quatemized form of a basic nitrogen. Heteroaryl groups include, for example, thienyl, furanyl, pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, oxadiazolyl, thiazolyl, isothiazolyl, thiadiazolyl, pyridyl, pyridazinyl, pyrimidinyl, and pyrazinyl.

[0161] When there are two or more rings, the rings may be arranged separate from each other or connected with each other. When two rings are connected with each other, they may be connected in a “fuse” arrangement (or connection motif), a “spiro” arrangement, or a “bridge” arrangement. As used herein, the term “fuse” refers to an arrangement where the two rings are connected with each other, side-by-side, sharing two bridgehead” atoms that are directly and immediately connected to each other. The fuse” connection motif differs from “spiro” connection motif in that there is one and only one “bridgehead" atom in the "spiro” motif; and differs from “bridge’' connection motif in that the two "bridgehead” atoms are not immediately connected to each other in the “bridge” motif. When a first ring is “fused with” a second ring, the "bridgehead” atoms are construed as belonging to both rings. Accordingly, if an embodiment provided here describes one such ring being a six-membered “carbocycle, then the six ring atoms include two “bridgehead” atoms and four additional atoms.And all these six ring atoms are carbons in order to be a “carbocycle.” For example, the group- faj]soutside the scope of “a 5-membered het.eroaryl fused with a 6- membered carbocycle” because one bridgehead atom is not carbon. For clarity, when one of the two rings fused together is aromatic, the shared bond does not disqualify the otherring from being a “cycloalkyl”' or “heterocycle”. For example, the groupHmay be interpreted as 5-membered heteroaiyl fused with a 5-membered cycloalkyl: and thegroupmay be interpreted as a 5-membered heteroaryl fused with a 6-membered heterocycle.

[0162] As used herein, the term “oxo” refers to the oxygen atom as a substituent connected to another atom by a double bond. It may be denoted as ' ()". The term oxo is the carbonyl group less the carbon atom.

[0163] As used herein, ™ represents a bond that is part of an aromatic system. It may be properly and alternatively represented as a single bond or double bond depending on how the aromatic system is depicted. For example,may be used to represent a 5- membered carbocycle fused with an aromatic system, such as a phenyl ring, at the two attachment points. The = bond may be properly represented as a single bond (e.g. as

[0164] refersw andQ"' , respectively. Moreover, each Qdmay be the same with each other or different from each other. Furthermore, when Q3is CR3, each RJmay be the same with each other or different from each other.

[0165] As used herein, the term “immune-mediated disease” encompasses a group of autoimmune or inflammatory' disorders in which immunological pathways play an important etiological and / or pathogenetic role. Such diseases are sometimes characterized by an alteration in cellular homeostasis. Immune-mediated diseases may be triggered by' environmental factors, dietary-' habits, infectious agents, and genetic predisposition. Immune-mediated disease includes, for example, psoriasis, atopic dermatitis, ulcerative colitis, Crohn’s disease, graft-versus-host disease, rheumatoid arthritis, and multiple sclerosis.

[0166] As used herein, the term “auto-antibody driven autoimmune disease” refers to a type of autoimmune disease that occurs when the immune system produces antibodies that attack the body’s own tissues or organs, causing inflammation and damage. Autoantibody driven autoimmune diseases includes, for example, systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and myasthenia gravis (MG).

[0167] As used herein, the term “treating” includes restraining, slowing, stopping, or reversing the progression or severity of an existing symptom or disorder.

[0168] As used herein, the term "patient" refers to a human.
