CYCLIC DIARYL ETHER COMPOUNDS AS ANTAGONISTS OF PROSTAGLANDIN D 2

RECEPTORS

RELATED APPLICATIONS

[0001] This application claims the benefit of U S provisional patent application no 61/028,804 entitled "Cyclic diaryl ether compounds as antagonists of prostaglandin D2 receptors" filed on February 14, 2008, which is incorporated by reference in its entirety

FBELD OF THE INVENTION

[0002] Descnbed herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments comprising such compounds, and methods of using such compounds to treat, prevent or diagnose diseases, disorders or conditions associated with prostaglandin D 2

BACKGROUND OF THE INVENTION

[0003] Prostaglandins are acidic lipids derived from the metabolism of arachidonic acid by the action of cyclooxygenase enzymes and downstream synthases Prostaglandins have a diverse range of activities and have a well recognized role in pain and inflammation Prostaglandin D 2 (PGD 2 ) is an acidic lipid mediator derived from the metabolism of arachidonic acid by cyclooxygenases and PGD 2 synthases PGD 2 is produced by mast cells, macrophages and T H 2 lymphocytes in response to local tissue damage as well as allergic inflammation in diseases such as asthma, rhinitis, and atopic dermatitis Exogenous PGD 2 applied to bronchial airways elucidates many characteristics of an asthmatic response suggesting that PGD 2 plays an important pro-inflammatory role in allergic diseases

[0004] PGD 2 bmds to a number of receptors, which include the thromboxane-type prostanoid (TP) receptor, PGD 2 receptor (DP, also known as DPi) and chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2, also known as DP 2 ) DP 2 is associated with promoting chemotaxis and activation of TH2 lymphocytes, eosinophils and basophils In particular, PGD 2 binds to DP 2 , and mediates its effects through a Q-dependant elevation in calcium levels and reduction of intracellular cyclic AMP In T H 2 lymphocytes, IL4, IL5 and IL13 cytokine production is stimulated. These cytokines have been implicated in numerous biological actions including, by way of example only, immunoglobulin E production, airway response, mucous secretion, and eosinophil recruitment

DETAILED DESCRIPTION OF THE INVENTION

[00123] Prostaglandin D 2 (PGD 2 ) is an acidic lipid derived from the metabolism of arachidonic acid by cyclooxygenases and PGD 2 synthases PGD 2 is produced by mast cells, macrophages and TH2 lymphocytes in response to local tissue damage as well as in response allergic inflammation observed in diseases such as asthma, rhinitis, and atopic dermatitis More specifically, exogenous PGD 2 applied to bronchial airways elicits many responses that are characteristic of acute asthma. [00124] PGD 2 is a major mast cell product that acts via two receptors, the D-type prostanoid (DP, also known as DPi) and the chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTH2, also known as DP 2 ) receptors DP 2 mediates the chemotaxis of eosinophils, basophils, and Th2 lymphocytes, and DPj receptor plays an important role in eosinophil trafficking DPi antagonists do not inhibit the release of eosinophils when induced by the DP 2 -selective agonists However, eosinophils in human bone marrow specimens express DPi and DP 2 receptors at similar levels and human peripheral blood expresses both DPi and DP 2 , but the DPi receptor is expressed at lower levels In agreement with this, the chemotaxis of human peripheral blood eosinophils is inhibited by both DPi and DP 2 antagonists Accordingly, DPi, DP 2 and dual DP 1 /DP 2 antagonists are useful m the treatment of allergic inflammation

[00125] Activation OfDP 2 is associated with chemotaxis and activation of T H 2 lymphocytes, eosinophils and basophils In particular, PGD 2 binds to DP 2 and mediates many of its effects through a Gi-dependent elevation of intracellular calcium levels and reduction of cyclic AMP La TH2 lymphocytes, TLA, DLS and ILl 3 cytokine production are also stimulated by DP 2 activation These

cytokines have been implicated in numerous biological actions including, by way of example only, immunoglobulin E production, airway response, mucous secretion, and eosinophil recruitment. [00126] The terms CRTH2 and DP 2 , refer to the same receptor and are used interchangeably herein. Likewise, another common name for DP is DPi, and the two terms are used interchangeably herein. Illustrative Biological Activity

[00127] Prostaglandins (PGs) are recognized physiological lipid acid mediators produced by the release of arachidonic acid from cell membrane phospholipids and converted to prostaglandins by the action of COXi and COX 2 cyclooxygenases and PG synthases. The cyclooxygenases sequentially convert arachidonic acid to cyclic endoperoxide prostaglandin G 2 (PGG 2 ) and subsequently, prostaglandin H 2 (PGH 2 ). Depending on the tissue, physiological signal, and/or synthase type, PGH 2 can be converted to numerous different prostaglandins, such as PGIi 2 , PGD 2 , PGF 2 O, and PGI 2 as well as thromboxane A 2 , another eicosanoid signaling molecule. These mediators then elicit a wide variety of physiological responses including vasoconstriction or dilation, platelet aggregation, calcium transport, pain sensitization, hormone release, inflammatory and immune response, and cellular growth.

[00128] Prostaglandin D 2 is a major metabolite produced from the PGH 2 intermediate via hematopoietic PGD 2 synthase or lipocalin PGD 2 synthase. In the brain and central nervous system, PGD 2 is produced and thought to function in pain perception and sleep regulation. In other tissues, PGD 2 is produced primarily in immunoglobulin E (IgE) activated mast cells and to a lesser extent, in macrophages, dendritic cells, T helper 2 (TH2) lymphocytes and other leukocytes. In the cell, PGD 2 is rapidly metabolized and converted to other downstream effectors including A 12 PGJ 2 , 9αl lβPGF 2 , 13,14-dihydro-15-keto-PGD 2 , and 15^eOXy-A 12114 PGD 2 ..

[00129] Mast-cell-derived PGD 2 is produced in high concentrations in response to an allergen challenge. Studies in preclinical species have observed the following features when PGD 2 is applied to in vivo preparations, or its overproduction is engineered by genetic manipulation:

-Vasodilatation leading to erythema (flare) and -potentiation of oedema (wheal).

-Recruitment of eosinophils and TH2 lymphocytes.

-Modulation of TH2-cytokine production.

-Bronchoconstriction.

[00130] Injection OfPGD 2 into human skin has been shown to produce a long lasting erythema, to potentiate the effects of other mediators on induration and leukocyte infiltration in human skin and to enhance oedema formation in rat skin. It is most likely that these effects OfPGD 2 , like those of other vasodilator prostaglandins, are due to an increased blood flow to the inflamed lesion and are, therefore, most likely to be mediated predominantly by the DPi receptor. Although these observations make it clear that DPi mediates the vascular effects OfPGD 2 , the capacity OfPGD 2 to promote the cellular changes associated with inflammation is not due to an action on DPi.

[001311 The main receptors that are activated by PGD 2 or its metabolites and mediate its effects are DP 1 , CRTH2 (or DP 2 ) and TP

[00132] DP 1 (or DP) is a G-protein coupled seven-transmembrane receptor that, upon activation by PGD 2 binding, leads to an increase in intracellular cAMP levels DPi is expressed in the brain, bronchial smooth muscle, vascular and airway smooth muscle, dendritic cells, and platelets and induces PGD 2 dependent bronchodilation, vasodilation, platelet aggregation inhibition, and suppression of cytokine production Genetic analysis of DPi function using knock-out mice has shown that mice lacking DP do not develop asthmatic responses in an ovalbumin-induced asthma model Analysis of selective DP anatgonists in guinea pig allergic rhinitis models demonstrated dramatic inhibition of early nasal responses, as assessed by sneezing, mucosal plasma exudation and eosinophil infiltration DP antagonism alleviate allergen-induced plasma exudation in the conjunctiva in a guinea pig allergic conjuctivms model and antigen-induced esinophil infiltration into the lung in a guinea pig astrna model

[00133] Much of the pro-inflammatory activity OfPGD 2 is through interaction with DP 2 (or CRTH2) DP 2 is a G-protein coupled receptor and is typically highly expressed in T H 2 lymphocytes, eosinophils and basophils DP 2 activation functions to directly activate and recruit T H 2 lymphocytes and eosinophils Activated TH2 lymphocytes produce and secrete inflammatory cytokines including UA, IL5, and IL13 Despite binding PGD 2 with a similar affinity as DPi, DP 2 is not structurally related to DPi and signals through a different mechanism- the effects of DP 2 are mediated through Gi-dependent elevation in intracellular calcium levels and reduction m intracellular levels of cyclic AMP DP 2 activation is important m eosinophil recruitment in response to allergic challenge in such tissues as nasal mucosa, bronchial airways, and skin The application of either PGD 2 or selective DP 2 agonists both exacerbate and enhance allergic responses in lung and skin. DP 2 activation appears to have a crucial role in mediating allergic responses, and thus the use of antagonists OfPGD 2 activation of the DP 2 receptor are an attractive approach to treat the inflammatory component of allergic diseases such as asthma, rhinitis, and dermatitis

[00134] TP receptors primarily function to antagonize DP] receptor's effects such as promoting bronchoconstπction, vasoconstriction, and platelet aggregation. While TP receptor's main ligand is thromboxane A 2 , it also binds and is activated by the PGD 2 derivative, 9αl 1 βPGF 2 TP is a Gq- coupled prostanoid receptor that binds thromboxane with high affinity, promoting platelet aggregation and constriction of both vascular and airway smooth muscle PGD 2 activates the TP receptor in human bronchial muscle, probably through the formation of the 11-ketoreductase metabolite 9αl 1 βPGF2 The bronchoconstπctor effects of TP dominate over the bronchodilator effects of DPi in the airways

[00135] DP] and DP 2 have crucial, and complementary, roles in the physiological response of animals to PGD 2 and bloackade of either one or both of these receptors may prove beneficial in

alleviating allergic diseases or conditions triggered by PGD 2 , such as, but not limited to, allergic rhinitis, asthma, dermatitis, and allergic conjunctivitis.

[00248] The term "acceptable" with respect to a formulation, composition or ingredient, as used herein, means having no persistent detrimental effect on the general health of the subject being treated

[00249] The term "modulate," as used herein, means to interact with a target either directly or indirectly so as to alter the activity of the target, including, by way of example only, to enhance the activity of the target, to inhibit the activity of the target, to limit the activity of the target, or to extend the activity of the target

[00250] The term "modulator," as used herein, refers to a molecule that interacts with a target either directly or indirectly The interactions include, but are not limited to, the interactions of an agonist, partial agonist, an inverse agonist and antagonist In one embodiment, a modulator is an antagonist

[00251] The term "agonist," as used herein, refers to a molecule such as a compound, a drug, an enzyme activator or a hormone modulator that binds to a specific receptor and taggers a response in the cell An agonist mimics the action of an endogenous ligand (such as prostaglandin, hormone or neurotransmitter) that binds to the same receptor

[00252] The term "antagonist," as used herein, refers to a molecule such as a compound, which diminishes, inhibits, or prevents the action of another molecule or the activity of a receptor site

Antagonists include, but are not limited to, competitive antagonists, non-competitive antagonists, uncompetitive antagonists, partial agonists and inverse agomsts

[00253] Competitive antagonists reversibly bind to receptors at the same binding site (active site) as the endogenous ligand or agonist, but without activating the receptor

[00254] Non-competitive antagonists (also known as allosteπc antagonists) bind to a distinctly separate binding site from the agonist, exerting their action to that receptor via the other binding site

Non-competitive antagonists do not compete with agonists for binding The bound antagonists may result in a decreased affinity of an agonist for that receptor, or alternatively may prevent conformational changes m the receptor required for receptor activation after the agonist bmds

[00255] Uncompetitive antagonists differ from non-competitive antagonists in that they require receptor activation by an agonist before they can bind to a separate allosteric binding site.

[00256] Partial agonists are defined as drugs which, at a given receptor, might differ in the amplitude of the functional response that they elicit after maximal receptor occupancy. Although they are agonists, partial agonists can act as a competitive antagonist if co-administered with a full agonist, as it competes with the full agonist for receptor occupancy and producing a net decrease in the receptor activation observed with the full agonist alone.

[00257] An inverse agonist can have effects similar to an antagonist, but causes a distinct set of downstream biological responses. Constitutively active receptors which exhibit intrinsic or basal activity can have inverse agonists, which not only block the effects of binding agonists like a classical antagonist, but inhibit the basal activity of the receptor.
