/^-substituted indole derivatives as PGE2 receptor modulators

The present invention relates to novel V-substituted indole derivatives of formula (I) and their use as pharmaceuticals. The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more compounds of formula (I), and their use as modulators of the PGE2 receptors EP2 (alias PTGER2, alias PGE2 Receptor EP2 Subtype) and/or EP4 (alias PTGER4, alias EP4R, alias PGE2 Receptor EP4 Subtype). The compounds of formula (I) may especially be used as single agents or in combination with one or more therapeutic agents and/or chemotherapy and/or radiotherapy and/or immunotherapy in the prevention/prophylaxis or treatment of cancers; in particular the prevention/prophylaxis or treatment of melanoma; lung cancer; bladder cancer; renal carcinomas; gastro-intestinal cancers; endometrial cancer; ovarian cancer; cervical cancer; and neuroblastoma.

Prostaglandin E2 (PGE2) is a bioactive lipid that can elicit a wide range of biological effects associated with inflammation and cancer. PGE2 belongs to the prostanoid family of lipids. Cyclooxygenase (COX) is the rate-limiting enzyme in the synthesis of biological mediators termed prostanoids, consisting of prostaglandin PGD2, PGE2, PGF2a, prostacyclin PGI2, and thromboxane TXA2. Prostanoids function via activation of seven transmembrane G- protein-coupled receptors (GPCRs), in particular EP1 , EP2, EP3, and EP4 are receptors for PGE2. Activation of both EP2 and EP4 by PGE2 stimulates adenylate cyclase, resulting in elevation of cytoplasmic cAMP levels to initiate multiple downstream events via its prototypical effector Protein kinase A. In addition, PGE2 is also able to signal via PI3K/AKT and Ras-MAPK/ERK signalling

Cancers figure among the leading causes of death worldwide. Tumors are comprised of abnormally proliferating malignant cancer cells but also of a functionally supportive microenvironment. This tumor microenvironment is comprised of a complex array of cells, extracellular matrix components, and signaling molecules and is established by the altered communication between stromal and tumor cells. As tumors expand in size, they elicit the production of diverse factors that can help the tumor to grow such as angiogenic factors (promoting ingrowth of blood vessels) or that can help to evade the attack of the host immune response. PGE2 is such an immuno-modulatory factor produced in tumors.

It is well established that COX2, mainly via PGE2, promotes overall growth of tumors and is upregulated and correlates with clinical outcome in a high percentage of common cancers, especially colorectal, gastric, esophageal, pancreatic, breast and ovarian cancer. High COX-2 and PGE2 expression levels are associated with neoplastic transformation, cell growth, angiogenesis, invasiveness, metastasis and immune evasion.

The finding that COX2 is over-expressed and plays an important role in carcinogenesis in gastrointestinal (Gl) cancers including among others esophagus, gastric and colorectal cancers has led to the fact that COX-inhibitors (Coxibs), including Celecoxib, and other nonsteroidal anti-inflammatory drugs (NSAID), including aspirin, are among the most studied cancer chemopreventive agents in development today (for review see for example Wang R et al, Curr Pharm Des. 2013;19(1 ): 115-25; Garcia Rodriguez LA et al, Recent Results Cancer Res. 2013;191 :67-93, Sahin IH et al, Cancer Lett. 2014 Apr 10;345(2):249-57; Drew DA et al, Nat Rev Cancer 2016, 16:173; Brotons C et al, Am J Cardiovasc Drugs. 2015 Apr; 15(2):113)

In addition to COX2 and PGE2, also EP receptors, especially EP2 and EP4, are aberrantly over-expressed in multiple types of cancers, especially in gastro-intestinal (Gl) cancers and pancreatic cancer. Furthermore, the over- expression of PGE2 and/or EP2 and/or EP4 correlates with diseases progression in some cancer types such as oesophageal squamous cell carcinoma (Kuo KT et al, Ann Surg One 2009; 16(2), 352-60); squamous cell carcinoma of the lung (Alaa M et al, Int J Oncol 2009, 34(3); 805-12); prostate cancer (Miyata Y et al, Urology 2013, 81(1):136- 42); Badawi AF and Badr MZ Int J Cancer. 2003, 103(1):84-90); head and neck squamous cell carcinoma (Gallo O et al, Hum Pathol. 2002, 33(7)708-14).

In accordance to studies performed with Coxibs, in mice, knockout of either COX1 , COX2, microsomal prostaglandin E synthase 1 (mPTGESI), EP2 or EP4 resulted in reduced tumor incidence and progression in different tumor models. Conversely, overexpression of COX2 or mPTGESI in transgenic mice resulted in increased tumor incidence and tumor burden (for review see Nakanishi M. and Rosenberg D.W., Seminars in Immunopathology 2013, 35: 123-137; Fischer SM et al Cancer Prev Res (Phila) 2011 Nov;4(11):1728-35; Fulton AM et al Cancer Res 2006; 66(20); 9794-97).

Several pharmacological studies to inhibit tumor growth and progression using EP receptor antagonists or COX2 inhibitors in different tumor models have been conducted in mice. Among others, EP antagonists and/or COX2 inhibitors reduced tumor growth and metastasis in experimental models of colorectal cancer (e.g Yang L et al Cancer Res 2006, 66(19), 9665-9672; Pozzi A.et al JBC 279(28); 29797-29804), lung carcinomas (Sharma S et al Cancer Res 2005 65(12), 5211-5220), gastro-intestinal cancer (Oshima H et al Gastroenterology 2011 , 140(2); 596- 607; Fu SL et al world J Gastroenterol 2004, 10(13); 1971-1974), breast cancer (Kundu N et al, Breast Cancer Res Treat 117, 2009; 235-242; Ma X et al, Oncolmmunology 2013; Xin X et al Lab Investigation 2012, 1-14; Markosyan N et al; Breast Cancer Res 2013, 15:R75), prostate cancer (Xu S et al, Cell Biochem Biophys 2014, Terada et al Cancer Res 70(4) 2010; 1606-1615), pancreatic cancer (Al-Wadei HA et al, PLOS One 2012, 7(8):e43376; Funahashi H et al, Cancer Res 2007, 67(15)7068-71). COX2 inhibitors were approved for the treatment of familial adenomatous polyposis (FAP) which is an inherited pre-disposition syndrome for colorectal cancer, but later retracted due to cardiovascular side effects.

Mechanistically, PGE2 signalling is mainly involved in the crosstalk between tumor and stromal cells, thereby creating a microenvironment which is favourable for the tumor to grow. In particular, PGE2 signalling via EP2 and EP4 can for example (i) suppress the cytotoxicity and cytokine production of natural killer cells, (ii) skew the polarization of tumor-associated macrophages towards tumor-promoting M2 macrophages (see for example Nakanishi Y et al Carcinogenesis 2011 , 32:1333-39), (iii) regulate the activation, expansion and effector function of both Tregs (regulatory T cells) and MDSC (myeloid derived suppressor cells), which are potent immunosuppressive cells that accumulate in tumors both in patients and in experimental animal models (see for example Sharma S et al, Cancer Res 2005, 5(12):5211-20; Sinha P et al Cancer Res 2007, 67(9), 4507-4513; Obermajer N et al, Blood 2011 , 118(20):5498-5505); (iv) down-regulate IFN-γ, TNF-a IL-12 and IL-2 expression in immune cells such as natural killer cells, T-cells, dendritic cells and macrophages, impairing the ability of these immune cells to induce tumor cell apoptosis and restrain tumorigenesis (see for example Bao YS et al, Int Immunopharmacol. 2011 ;11 (10): 1599-605; Kim JG and Hahn YS, Immunol Invest. 2000;29(3):257-69; Demeuere CE et al, Eur J Immunol. 1997;27(12):3526- 31 ; Mitsuhashi M et al, J Leukoc Biol. 2004;76(2):322-32; Pockaj BA et al , Ann Surg Oncol. 2004;11(3):328-39; (v) suppress activation, IL-2 responsivness, expansion and cytotoxicity of T-cells thereby contributing to local immunsuppresion (see for example Specht C et al, Int J Cancer 200191 :705-712); (vi) inhibit maturation of dendritic cells, their ability to present antigens and to produce IL-12, resulting in abortive activation of cytotoxic T-cells (see for example Ahmadi M et al, Cancer Res 2008, 68(18)7250-9; Stolina M et al, J Immunol 2000, 164:361-70); (vii) regulate tumor angiogenesis (formation of new blood vessels for nutrient and oxygen supply) by enhancing endothelial cell motility and survival as well as by increasing the expression of VEGF (vascular endothelial growth factor) (see for example Zhang Y and Daaka Y, Blood 2011 ;118(19):5355-64; Jain S et al, Cancer Res. 2008; 68(19):7750-9; Wang and Klein, Molecular Carcinogenesis 2007, 46:912-923; (viii) enhance tumor cell survival (via PI3K/AKT and MAPK signalling). For review see for example Kalinski P, J Immunol 2012, 188(1), 21-28; Obermajer N et al, Oncoimmunology 1(5), 762-4; Greenhough A et al, carcinogenesis 2009, 30(3), 377-86; Wang D and Dubois RN, Gut 2006, 55, 115-122; Harris SG e al Trends Immunol 2002, 22, 144-150).

Coxibs have been shown to render tumor cells more sensitive to radiation and chemotherapy and several clinical trials have been performed or are ongoing combining Coxibs with radio- and/or chemotherapy (for review see e.g Ghosh N et al, Pharmacol Rep. 2010 Mar-Apr;62(2):233-44; Davis TW et al, Am J Clin Oncol. 2003, 26(4):S58-61 ; see also Higgins JP et al, Cancer Biol Ther 2009, 8:1440-49).

Furthermore, there is some evidence of additive effects and/or synergy between Coxibs and epidermal growth factor receptor (EGFR) inhibitors (see for example Zhang X et al, Clin Cancer Res. 2005, 11 (17):6261-9; Yamaguchi NH et al, J Gastrointest Oncol. 2014, 5(1):57-66); and with aromatase inhibitors (see for example Generali D et al, Br J Cancer. 2014;111(1):46-54; Lustberg MB et all, Clin Breast Cancer. 2011 Aug;11(4):221-7; Falandry C et al, Breast Cancer Res Treat. 2009 Aug;116(3):501-8); Chow LW et al, J Steroid Biochem Mol Biol. 2008, 111 (1 -2):13-7). Moreover, additive/synergistic effects have been seen in different mouse tumor models when Aspirin (a COX1/2 inhibitor) was combined with and anti-VEGF antibody (Motz GT et al; Nat Med 2014 20(6):607) and this combination is currently under investigation in clinical trials (NCT02659384).

Recently, it has been shown that, if combined, different immunotherapeutic approaches can have enhanced antitumor efficacy. Due to the immune-modulatory properties of PGE2, Coxibs have thus also been used in combination with different immunotherapeutic approaches. In particular, additive or even synergistic effects could be observed when Coxibs were combined with dendritic cell vaccination in a rat glioma model and in a mouse mesothelioma or melanoma model (Zhang H et al, Oncol Res. 2013;20(10):447-55; Veltman JD et al, BMC Cancer. 2010;10:464; Toomey D et all, Vaccine. 2008 Jun 25;26(27-28):3540-9); with granulocyte-macrophage colony-stimulating factor (GM-CSF) in mouse brain tumors (Eberstal S et al, Int J Cancer. 2014 Jun 1 ;134(11):2748-53); with interferon gamma (IFN-γ) in brain tumors (Eberstal S et al, Cancer Immunol Immunother. 2012, 61 (8): 1191-9); with dendritic cell vaccination or with GM-CSF in a mouse breast cancer model (Hahn T et al, Int J Cancer. 2006,118(9):2220-31); and with adenoviral interferon beta (IFN-β) therapy in a mouse mesothelioma model (DeLong P et al, Cancer Res. 2003 Nov 15;63(22):7845-52). Along these lines, additive or even synergistic effects of Coxibs and/or EP2 and/or EP4 antagonists can also be envisaged with agents acting on cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) such as anti-CTLA-4 antibodies; anti-TIM-3 antibodies, anti-Lag-3 antibodies; anti-TIGIT antibodies; or, in particular, with agents acting on programmed cell death protein 1 (PD1), such as anti-PD1 or anti-PDL1 (programmed cell death ligand 1) antibodies (Yongkui Li et al Oncoimmunology 2016, 5(2):e1074374; Zelenay S et al, Cell 2015, 162; 1-14; WO2013/090552, which indicates a synergistic effect of dual EP2 and EP4 blockade in combination with agents acting on PD1J.

Adenosine is another endogenous factor with anti-inflammatory properties that is generated through the activity of ectonucleotidases, CD39 and CD73, expressed on various cell types, including regulatory T cells (Treg) (Mandapathil M et al, J Biol Chem. 2010; 285(10):7176-86). Immune cells also respond to Adenosine, because they bear receptors for ADO, which are mainly of the A2a/A2b type (Hoskin DW, et al, Int J Oncol 2008, 32:527-535). Signaling via Adenosine receptors and EP2/EP4 receptors converges on the cytoplasmic adenylyl cyclase, leading to up-regulation of cAMP. It was shown that Adenosine and PGE2 cooperate in the suppression of immune responses mediated by regulatory T cells (Mandapathil M et al, J Biol Chem. 2010; 285(36):27571-80; Caiazzo E et al, Biochem Pharmacol. 2016; 112:72-81).

Thus, the present EP2 and/or EP4 antagonists may be useful, alone, or in combination with with one or more therapeutic agents and/or chemotherapy and/or radiotherapy and/or immunotherapy; in particular in combination with chemotherapy, radiotherapy, EGFR inhibitors, aromatase inhibitors, anti-angiogenic drugs, adenosine inhibitors, immunotherapy such as especially PD1 and/or PDL1 blockade, or other targeted therapies; for the prevention / prophylaxis or treatment of cancers, notably for the prevention / prophylaxis or treatment of skin cancer including melanoma including metastatic melanoma; lung cancer including non-small cell lung cancer; bladder cancer including urinary bladder cancer, urothelial cell carcinoma; renal carcinomas including renal cell carcinoma, metastatic renal cell carcinoma, metastatic renal clear cell carcinoma; gastro-intestinal cancers including colorectal cancer, metastatic colorectal cancer, familial adenomatous polyposis (FAP), oesophageal cancer, gastric cancer, gallbladder cancer, cholangiocarcinoma, hepatocellular carcinoma, and pancreatic cancer such as pancreatic adenocarcinoma or pancreatic ductal carcinoma; endometrial cancer; ovarian cancer; cervical cancer; neuroblastoma; prostate cancer including castrate-resistant prostate cancer; brain tumors including brain metastases, malignant gliomas, glioblastoma multiforme, medulloblastoma, meningiomas; breast cancer including triple negative breast carcinoma; oral tumors; nasopharyngeal tumors; thoracic cancer; head and neck cancer; leukemias including acute myeloid leukemia, adult T-cell leukemia; carcinomas; adenocarcinomas; thyroid carcinoma including papillary thyroid carcinoma; choriocarcinoma; Ewing's sarcoma; osteosarcoma; rhabdomyosarcoma; Kaposi's sarcoma; lymphoma including Burkitt's lymphoma, Hodgkin's lymphoma, MALT lymphoma; multiple myelomas; and virally induced tumors.

In addition, selective or dual EP2 and/or EP4 antagonists may be useful in several other diseases or disorders responding for example to treatment with COX2 inhibitors, with the advantage that EP2 and/or EP4 antagonists should not possess the potential cardiovascular side effects seen with COX2 inhibitors, which are mainly due to interference with PGI2 and TXA2 synthesis (see for example Boyd MJ et al, bioorganic and medicinal chemistry letters 21 , 484, 2011). For example, blockade of prostaglandin production by COX inhibitors is the treatment of choice for pain, including especially inflammatory pain and painful menstruation. Thus EP2 and/or EP4 and/or dual EP2/EP4 antagonists may be useful for the treatment of pain, especially inflammatory pain. Evidence from EP2 knockout mice suggest that EP2 antagonists can be used for the treatment of inflammatory hyperalgesia (Reinold H et al, J Clin Invest 2005, 115(3):673-9). In addition, EP4 antagonists have beneficial effect in vivo in inflammatory pain models (eg Murase A, Eur J Pharmacol 2008; Clark P, J Pharmacol Exp Ther. 2008; Maubach KA Br J Pharmacol. 2009; Colucci J Bioorg Med Chem Lett. 2010, Boyd MJ et al, Bioorg Med Chem Lett 2011 , Chn Q et al Br J Phramacol 2010, Nakao K et al, J Pharmacol Exp Ther. 2007 Aug;322(2):686-94). Administration of an EP2 in combination with an EP4 antagonist showed significant, but partial inhibition of joint inflammation in mouse collagen- induced arthritis model (Honda T et al J Exp Med 2006, 203(2):325-35).

EP2 and/or dual EP2/EP4 antagonists may be of use to decrease female fertility, i.e. they have been shown to prevent pregnancy if used as contraceptive in macaques (Peluffo MC et al Hum Reprod 2014). EP2 knockout mice have decreased fertility, smaller litter sizes and reduced cumulus expansion (Matsumoto et al, Biology of reproduction 2001 , 64; 1557-65; Hitzaki et al, PNAS 1999, 96(18), 10501-10506; Tilley SL J Clin Inves 1999, 103(11): 1539-45; Kennedy CR et al, Nat Med 1999 5(2):217-20).

There is also rationale that EP2 and/ or EP4 antagonists may be of use to prevent or treat endometriosis: for example EP2, EP3 and EP4 and COX2 are overexpressed in endometriosis cell lines and tissues (e.g. Santulli P et al J Clin Endocrinol Metab 2014, 99(3):881-90); antagonist treatment was shown to inhibit the adhesion of endometrial cells in vitro (Lee J et al Biol Reprod 2013, 88(3):77; Lee J et al Fertil Steril 201 , 93(8):2498-506); COX2 inhibitors have been shown to reduce endometric lesions in mice via EP2 (Chuang PC et al, Am J Pathol 2010, 176(2):850-60); and antagonist treatment has been shown to induce apoptosis of endometric cells in vitro (Banu SK et al, MOI endocrinol 2009, 23(8) 1291-305).

Dual EP2/EP4 antagonists, or the combination of a selective EP2 antagonists with a selective EP4 antagonist, may be of potential use for autoimmune disorders; e.g. they have been shown to be effective in mouse model for multiple sclerosis (MS) (Esaki Yet al PNAS 2010, 107(27):12233-8; Schiffmann S et al, Biochem Pharmacol. 2014, 87(4): 625-35; see also Kofler DM et al J Clin Invest 2014, 124(6):2513-22). Activation of EP2 / EP 4 signalling in cells in vitro (Kojima F et al Prostaglandins Other Lipid Mediat 2009, 89:26-33) linked dual or selective EP2 and/or EP4 antagonists to the treatment of rheumatoid arthritis. Also, elevated levels of PGE(2) have been reported in synovial fluid and cartilage from patients with osteoarthritis (OA) and it has been shown that PGE2 stimulates matrix degradation in osteoarthitis chondrocytes via the EP4 receptor (Attur M et al, J Immunol. 2008; 181 (7):5082-8).

EP4 overexpression is associated with enhanced inflammatory reaction in atherosclerotic plaques of patients (Cipollone F et al, Artherioscler Thromb Vase Biol 2005, 25(9); 1925-31), thus the use of EP4 and/or dual EP2/EP4 antagonists may be indicated for plaque stabilization and prevention / prophylaxis of acute ischemic syndromes. In addition, EP4 deficiency suppresses early atherosclerosis, by compromising macrophage survival (Babaev VR et al, Cell Metab. 2008 Dec;8(6):492-501)

EP2 and/or dual EP2/EP4 antagonists may also be useful in the treatment of pneumonia: intrapulmonary administration of apoptotic cells demonstrated that PGE(2) via EP2 accounts for subsequent impairment of lung recruitment of leukocytes and clearance of Streptococcus pneumoniae, as well as enhanced generation of IL-10 in vivo (Medeiros Al et al J Exp Med 2009 206(1 ):61 -8).

EP2 and/or dual EP2/EP4 antagonists may in addition be useful for the treatment of neurodegenerative diseases (for review see Cimino PJ et al, Curr Med Chem. 2008;15(19):1863-9). EP2 receptor accelerates progression of inflammation in a mouse model of amyotrophic lateral sclerosis (ALS) (Liang X et al, Ann Neurol 2008, 64(3):304- 14); COX2 inhibitors have been shown to be neuroprotective in rodent models of stroke, Parkinson disease and ALS (for review see Liang X et al J Mol Neurosci 2007, 33(1):94-9), decreased neurotoxicity was observed in EP2 knockout mice treated with parkinsonian toxican (Jin J et al, J Neuroinflammation 2007, 4:2), PGE2 via EP2 aggravates neurodegeneration in cultured rat cells (Takadera T et al, Life Sci 2006, 78(16): 1878-83); Reduced amyloid burden was observed in Alzheimer's disease mouse model if crossed with EP2 knockout mice (Liang X et al J Neurosci 2005, 25(44):10180-7; Keene CD etal, Am J Pathol. 2010, 177(1):346-54). EP2 null mice are protected from CD14-dependent/ innate immunity mediated neuronal damage in neurodegenerative disease (Shie FS et al Glia 2005, 52(1):70-7); PGE2 via EP2 increases amyloid precursor protein (APP) expression in cultured rat microglial cells (Pooler AM et al Neurosci. Lett. 2004, 362(2):127-30). EP2 antagonist limits oxidative damage from activation of innate immunity (intracranial injection of LPS) in the brain and could be used for Alzheimer or HIV associated dementia (Montine TJ et al, J Neurochem 2002, 83(2):463-70). In an Alzheimer's disease mouse model cognitive function could be improved by genetic and pharmacological inhibition of EP4 (Hoshino T et al, J Neurochem 2012, 120(5)795-805).

EP2 and/or dual EP2/EP4 antagonists may also be useful to treat autosomal dominant polycystic kidney disease (ADPKD): PGE2 via EP2 induces cystogenesis of human renal epithelial cells; and EP2 was found to be overexpressed in patient samples (Elberg G et al, Am J Physiol Renal Physiol 2007, 293(5):F1622-32).

EP4 and/or dual EP2/EP4 antagonists may also be useful to treat osteoporosis: PGE2 stimulates bone resorption mainly via EP4 and partially via EP2 (Suzawa T et all, Endocrinology. 2000 Apr; 141 (4): 1554-9), EP4 knockout mice show impaired bone resorption (Miyaura C et al, J Biol Chem 2000, 275(26): 19819-23) and an EP4 antagonists showed partial inhibition of PGE(2)-stimulated osteoclastogenesis and osteoclastic bone resorption (Tomita M et al, Bone. 2002 Jan;30(1):159-63).

WO2008/152093 discloses selective EP2 receptor modulators which comprise an indole ring linked to the rest of the molecule in position 3, and a pyrimidine moiety which however is not substituted with a directly linked aromatic substituent. WO2006/044732 discloses pyrimidine compounds which are modulators of PGD2 claimed to be useful e.g. in the treatment of allergic diseases; however for example the exemplified compound CAS 1001913-77-4 has been tested to be inactive on both the EP2 and the EP4 receptor in the in vitro assay set out in the experimental part below. WO2008/006583 discloses pyrimidin derivatives which are ALK-5 inhibitors. WO2006/044732 and WO2008/039882 disclose certain pyrimidine derivatives as protaglandin D2 receptor antagonists. Pyrimidin-2-yl derivatives are disclosed in WO2013/020945, WO2012/127032, WO2011/144742, Bioorg. Med. Chem 2011 , 21 (13) 4108-4114 and Bioorg. Med. Chem 2011 , 21(1) 66-75. Certain indole-1-acetamide compounds are known as library compounds, e.g. CAS 1448123-30-5 and CAS 1448075-88-4. Further compounds which are claimed to be active as anti-cancer agents are disclosed in WO2006/128129, WO2008/008059 and Bioorg. Med. Chem 2013, 21(2), 540- 546.

The present invention provides novel W-substituted indole derivatives of formula (I) which are modulators of the prostaglandin 2 receptors EP2 and/or EP4. Certain compounds of the present invention are dual antagonists of both the EP2 and the EP4 receptor.

The compounds of formula (I) may contain one or more stereogenic or asymmetric centers, such as one or more asymmetric carbon atoms, which are allowed to be present in (R)- as well as (S)-configuration. The compounds of formula (I) may further encompass compounds with one or more double bonds which are allowed to be present in Z- as well as E-configuration and/or compounds with substituents at a ring system which are allowed to be present, relative to each other, in cis- as well as trans-configuration. The compounds of formula (I) may thus be present as mixtures of stereoisomers or preferably as pure stereoisomers. Mixtures of stereoisomers may be separated in a manner known to a person skilled in the art.

In case a particular compound (or generic structure) is designated as (R)- or (S)-enantiomer, such designation is to be understood as referring to the respective compound (or generic structure) in enriched, especially essentially pure, enantiomeric form. Likewise, in case a specific asymmetric center in a compound is designated as being in (R)- or (S)-configuration or as being in a certain relative configuration, such designation is to be understood as referring to the compound that is in enriched, especially essentially pure, form with regard to the respective configuration of said asymmetric center. In analogy, cis- or frans-designations are to be understood as referring to the respective stereoisomer of the respective relative configuration in enriched, especially essentially pure, form. Likewise, in case a particular compound (or generic structure) is designated as Z- or E-stereoisomer (or in case a specific double bond in a compound is designated as being in Z- or E-configuration), such designation is to be understood as referring to the respective compound (or generic structure) in enriched, especially essentially pure, stereoisomeric form (or to the compound that is in enriched, especially essentially pure, form with regard to the respective configuration of the double bond).

The term "enriched", when used in the context of stereoisomers, is to be understood in the context of the present invention to mean that the respective stereoisomer is present in a ratio of at least 70:30, especially of at least 90:10 (i.e., in a purity of at least 70% by weight, especially of at least 90% by weight), with regard to the respective other stereoisomer / the entirety of the respective other stereoisomers. The term "essentially pure", when used in the context of stereoisomers, is to be understood in the context of the present invention to mean that the respective stereoisomer is present in a purity of at least 95% by weight, especially of at least 99% by weight, with regard to the respective other stereoisomer / the entirety of the respective other stereoisomers.

The present invention also includes isotopically labelled, especially ² H (deuterium) labelled compounds of formula (I) according to embodiments 1) to 31), which compounds are identical to the compounds of formula (I) except that one or more atoms have each been replaced by an atom having the same atomic number but an atomic mass different from the atomic mass usually found in nature. Isotopically labelled, especially ² H (deuterium) labelled compounds of formula (I) and salts thereof are within the scope of the present invention. Substitution of hydrogen with the heavier isotope ² H (deuterium) may lead to greater metabolic stability, resulting e.g. in increased in-vivo half-life or reduced dosage requirements, or may lead to reduced inhibition of cytochrome P450 enzymes, resulting e.g. in an improved safety profile. In one embodiment of the invention, the compounds of formula (I) are not isotopically labelled, or they are labelled only with one or more deuterium atoms. In a sub-embodiment, the compounds of formula (I) are not isotopically labelled at all. Isotopically labelled compounds of formula (I) may be prepared in analogy to the methods described hereinafter, but using the appropriate isotopic variation of suitable reagents or starting materials.

In this patent application, a bond drawn as a dotted line shows the point of attachment of the radical drawn. For example, the radical drawn below is the 2-methyl-1 H-indol-1 -yl group.

In some instances, the compounds of formula (I) may contain tautomeric forms. Such tautomeric forms are encompassed in the scope of the present invention. In case tautomeric forms exist of a certain residue, and only one form of such residue is disclosed or defined, the other tautomeric form(s) are understood to be encompassed in such disclosed residue. For example the group 2-oxo-2,3-dihydro-1 H-benzo[d]imidazol-5-yl is to be understood as also encompassing its tautomeric forms 2-hydroxy-1 H-benzo[d]imidazol-5-yl and 2-hydroxy-3H-benzo[d]imidazol-5- yl. Similarly, 5-oxo-4,5-dihydro-[1 ,2,4]oxadiazol-3-yl (alternatively named 5-oxo-4H-[1 ,2,4]oxadiazol-3-yl) encompasses its tautomeric form 5-hyd roxy- [1 , 2,4]oxad iazol-3-yl , and 3-oxo-2,3-dihydro-[1 ,2,4]oxadiazol-5-yl (alternatively named 3-oxo-2H-[1 ,2,4]oxadiazol-5-yl) encompasses its tautomeric form 3-hydroxy-[1 ,2,4]oxadiazol-5- yi-

Where the plural form is used for compounds, salts, pharmaceutical compositions, diseases and the like, this is intended to mean also a single compound, salt, or the like.

Any reference to compounds of formula (I) according to embodiments 1) to 31) is to be understood as referring also to the salts (and especially the pharmaceutically acceptable salts) of such compounds, as appropriate and expedient. The term "pharmaceutically acceptable salts" refers to salts that retain the desired biological activity of the subject compound and exhibit minimal undesired toxicological effects. Such salts include inorganic or organic acid and/or base addition salts depending on the presence of basic and/or acidic groups in the subject compound. For reference see for example "Handbook of Phramaceutical Salts. Properties, Selection and Use.", P. Heinrich Stahl, Camille G. Wermuth (Eds.), Wiley-VCH, 2008; and "Pharmaceutical Salts and Co-crystals", Johan Wouters and Luc Quere (Eds.), RSC Publishing, 2012.

Definitions provided herein are intended to apply uniformly to the compounds of formula (I), as defined in any one of embodiments 1) to 26), and, mutatis mutandis, throughout the description and the claims unless an otherwise expressly set out definition provides a broader or narrower definition. It is well understood that a definition or preferred definition of a term defines and may replace the respective term independently of (and in combination with) any definition or preferred definition of any or all other terms as defined herein. Whenever the group Ar ¹ or substituents thereof are further defined, such definitions are intended to apply mutatis mutandis also to the groups (Ar-I), (Ar-ll), (Ar-IV), (Ar-V), and (Ar-VI) and their respective substituents.

Whenever a substituent is denoted as optional, it is understood that such substituent may be absent, in which case all positions having a free valency (to which such optional substituent could have been attached to; such as for example in an aromatic ring the ring carbon atoms and / or the ring nitrogen atoms having a free valency) are substituted with hydrogen where appropriate.

The term "halogen" means fluorine, chlorine, bromine, or iodine; especially fluorine, chlorine, or bromine; preferably fluorine or chlorine.

The term "alkyl", used alone or in combination, refers to a saturated straight or branched chain hydrocarbon group containing one to six carbon atoms. The term "(C _x . _y )alkyl" (x and y each being an integer), refers to an alkyl group as defined before, containing x to y carbon atoms. For example a (Ci-6)alkyl group contains from one to six carbon atoms. Examples of alkyl groups are methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert.-butyl, 3-methyl-butyl, 2,2- dimethyl-propyl and 3,3-dimethyl-butyl. For avoidance of any doubt, in case a group is referred to as e.g. propyl or butyl, it is meant to be n-propyl, respectively n-butyl. Preferred are methyl and ethyl. Most preferred is methyl. Preferred for substituents of Ar ¹ being phenyl or 5- or 6-membered heteroaryl are methyl, ethyl, propyl, isobutyl, 1- methyl-propan-1-yl, tert.-butyl, 3-methyl-butyl.

The term "-(C _x . _y )alkylene-", used alone or in combination, refers to bivalently bound alkyl group as defined before containing x to y carbon atoms. Preferably, the points of attachment of a -(Ci _-y )alkylene group are in 1 ,1-diyl, in 1 ,2- diyl, or in 1 ,3-diyl arrangement. In case a (Co- _y )alkylene group is used in combination with another substituent, the term means that either said substituent is linked through a (Ci- _y )alkylene group to the rest of the molecule, or it is directly attached to the rest of the molecule (i.e. a (Co)alkylene group represents a direct bond linking said substituent to the rest of the molecule). The alkylene group -C2H4- refers to -CH2-CH2- if not explicitly indicated otherwise. For the linker X ¹ , examples of (Ci-3)alkylene groups are -CH2-, -CH(CH3)-, -C(CH3)2-, and -CH2-CH2-, especially -CH2- and -CH2-CH2-.

The term "alkoxy", used alone or in combination, refers to an alkyl-O- group wherein the alkyl group is as defined before. The term "(C _x . _y )alkoxy" (x and y each being an integer) refers to an alkoxy group as defined before containing x to y carbon atoms. For example a (Ci-4)alkoxy group means a group of the formula (Ci-4)alkyl-0- in which the term "(O-^alkyl" has the previously given significance. Examples of alkoxy groups are methoxy, ethoxy, n- propoxy, isopropoxy, n-butoxy, isobutoxy, sec.-butoxy and tert.-butoxy. Preferred are ethoxy and especially methoxy. Preferred for substituents of Ar ¹ being phenyl or 5- or 6-membered heteroaryl are methoxy, ethoxy, propoxy, butoxy, isobutoxy.

The term "chemotherapy" refers to the treatment of cancer with one or more cytotoxic anti-neoplastic agents ("cytotoxic chemotherapy agents"). Chemotherapy is often used in conjunction with other cancer treatments, such as radiation therapy or surgery. The term especially refers to conventional cytotoxic chemotherapeutic agents which act by killing cells that divide rapidly, one of the main properties of most cancer cells. Chemotherapy may use one drug at a time (single-agent chemotherapy) or several drugs at once (combination chemotherapy or polychemotherapy). Chemotherapy using drugs that convert to cytotoxic activity only upon light exposure is called photochemotherapy or photodynamic therapy. The term "cytotoxic chemotherapy agent" or "chemotherapy agent" as used herein refers to an active anti-neoplastic agent inducing apoptosis or necrotic cell death. When used in combination with the compounds of formula (I), the term especially refers to conventional cytotoxic chemotherapy agents such as:

a) alkylating agents (for example mechlorethamine, chlorambucil, cyclophosphamide, ifosfamide, streptozocin, carmustine, lomustine, melphalan, dacarbazine, temozolomide, fotemustine, thiotepa or altretamine; especially cyclophosphamide, carmustine, melphalan, dacarbazine, or temozolomide);

b) platinum drugs (especially cisplatin, carboplatin or oxaliplatin);

c) antimetabolite drugs (for example 5-fluorouracil, folic acid/leucovorin, capecitabine, 6-mercaptopurine, methotrexate, gemcitabine, cytarabine, fludarabine or pemetrexed; especially 5-fluorouracil, folic acid/leucovorin, capecitabine, methotrexate, gemcitabine or pemetrexed);

d) anti-tumor antibiotics (for example daunorubicin, doxorubicin, epirubicin, idarubicin, actinomycin-D, bleomycin, mitomycin-C or mitoxantrone; especially doxorubicin);

e) mitotic inhibitors (for example paclitaxel, docetaxel, ixabepilone, vinblastine, vincristine, vinorelbine, vindesine or estramustine; especially paclitaxel, docetaxel, ixabepilone or, vincristine); or

f) topoisomerase inhibitors (for example etoposide, teniposide, topotecan, irinotecan, diflomotecan or elomotecan; especially etoposide or irinotecan).

When used in combination with the compounds of formula (I), preferred cytotoxic chemotherapy agents are the above-mentioned alkylating agents (notably fotemustine.cyclophosphamide, ifosfamide, carmustine, dacarbazine and prodrugs thereof such as especially temozolomide or pharmaceutically acceptable salts of these compounds; in particular temozolomide); mitotic inhibitors (notably paclitaxel, docetaxel, ixabepilone,; or pharmaceutically acceptable salts of these compounds; in particular paclitaxel); platinum drugs (notably cisplatin, oxaliplatin and carboplatin); as well etoposide and gemcitabine.

Chemotherapy may be given with a curative intent or it may aim to prolong life or to palliate symptoms.

• Combined modality chemotherapy is the use of drugs with other cancer treatments, such as radiation therapy or surgery.

• Induction chemotherapy is the first line treatment of cancer with a chemotherapeutic drug. This type of chemotherapy is used for curative intent.

• Consolidation chemotherapy is the given after remission in order to prolong the overall disease free time and improve overall survival. The drug that is administered is the same as the drug that achieved remission.

• Intensification chemotherapy is identical to consolidation chemotherapy but a different drug than the induction chemotherapy is used.

• Combination chemotherapy involves treating a patient with a number of different drugs simultaneously. The drugs differ in their mechanism and side effects. The biggest advantage is minimising the chances of resistance developing to any one agent. Also, the drugs can often be used at lower doses, reducing toxicity. • Neoadjuvant chemotherapy is given prior to a local treatment such as surgery, and is designed to shrink the primary tumor. It is also given to cancers with a high risk of micrometastatic disease.

• Adjuvant chemotherapy is given after a local treatment (radiotherapy or surgery). It can be used when there is little evidence of cancer present, but there is risk of recurrence. It is also useful in killing any cancerous cells that have spread to other parts of the body. These micro metastases can be treated with adjuvant chemotherapy and can reduce relapse rates caused by these disseminated cells.

• Maintenance chemotherapy is a repeated low-dose treatment to prolong remission.

• Salvage chemotherapy or palliative chemotherapy is given without curative intent, but simply to decrease tumor load and increase life expectancy. For these regimens, a better toxicity profile is generally expected. "Simultaneously", when referring to an administration type, means in the present application that the administration type concerned consists in the administration of two or more active ingredients and/or treatments at approximately the same time; wherein it is understood that a simultaneous administration will lead to exposure of the subject to the two or more active ingredients and/or treatments at the same time. When administered simultaneously, said two or more active ingredients may be administered in a fixed dose combination, or in an equivalent non-fixed dose combination (e.g. by using two or more different pharmaceutical compositions to be administered by the same route of administration at approximately the same time), or by a non-fixed dose combination using two or more different routes of administration; wherein said administration leads to essentially simultaneous exposure of the subject to the two or more active ingredients and/or treatments. For example, when used in combination with chemotherapy and/or suitable targeted therapy, the present EP2/EP4 antagonists would possibly be used "simultaneously".

"Fixed dose combination", when referring to an administration type, means in the present application that the administration type concerned consists in the administration of one single pharmaceutical composition comprising the two or more active ingredients.

"Separately", when referring to an administration type, means in the present application that the administration type concerned consists in the administration of two or more active ingredients and/or treatments at different points in time; wherein it is understood that a separate administration will lead to a treatment phase (e.g. at least 1 hour, notably at least 6 hours, especially at least 12 hours) where the subject is exposed to the two or more active ingredients and/or treatments at the same time; but a separate administration may also lead to a treatment phase where for a certain period of time (e.g. at least 12 hours, especially at least one day) the subject is exposed to only one of the two or more active ingredients and/or treatments. Separate administration especially refers to situations wherein at least one of the active ingredients and/or treatments is given with a periodicity substantially different from daily (such as once or twice daily) administration (e.g. wherein one active ingredient and/or treatment is given e.g. once or twice a day, and another is given e.g. every other day, or once a week or at even longer distances). For example, when used in combination with radiotherapy, the present EP2/EP4 antagonists would possibly be used "separately".

By administration "over a period of time" is meant in the present application the subsequent administration of two or more active ingredients and/or treatments at different times. The term in particular refers to an administration method according to which the entire administration of one of the active ingredients and/or treatments is completed before the administration of the other / the others begins. In this way it is possible to administer one of the active ingredients and/or treatments for several months before administering the other active ingredient(s) and/or treatment(s).

Administration "over a period of time" also encompasses situations wherein the compound of formula (I) would be used in a treatment that starts after termination of an initial chemotherapeutic (for example an induction chemotherapy) and/or radiotherapeutic treatment and/or targeted therapy treatment, wherein optionally said treatment would be in combination with a further / an ongoing chemotherapeutic and/or radiotherapeutic treatment and/or targeted therapy treatment (for example in combination with a consolidation chemotherapy, an intensification chemotherapy, an adjuvant chemotherapy, or a maintenance chemotherapy; or radiotherapeutic equivalents thereof); wherein such further / ongoing chemotherapeutic and/or radiotherapeutic treatment and/or targeted therapy treatment would be simultaneously, separately, or over a period of time in the sense of "not given with the same periodicity".

The compounds of formula (I) as defined in embodiments 1) to 31) are also useful in a method of modulating an immune response in a subject having a tumor, comprising the administration of an effective amount of the compound of formula (I); wherein said effective amount reactivates the immune system in the tumor of said subject; wherein especially said effective amount:

• counteracts the polarization of tumor-associated macrophages towards tumor-promoting M2 macrophages; and/or

· down-regulates the activation, expansion and/or the effector function of immunosuppressive cells that have accumulated in a tumor (especially of regulatory T cells (Tregs) and/or myeloid derived suppressor cells (MDSC)); and/or

• up-regulates IFN-γ and/or TNF-a and/or IL-12 and/or IL-2 expression in immune cells such as natural killer cells, T-cells, dendritic cells and macrophages (leading to the induction of tumor cell apoptosis and/or restrained tumorigenesis); and/or

Optimum reaction conditions may vary with the particular reactants or solvents used, but such conditions can be determined by a person skilled in the art by routine optimisation procedures. In some cases the order of carrying out the following reaction schemes, and/or reaction steps, may be varied to facilitate the reaction or to avoid unwanted reaction products. In the general sequence of reactions outlined below, the generic groups R ¹ , R ² , R ³ , R ^4a , R ^4b , R ^5a , R ^5b and Ar ¹ are as defined for formula (I).

In some cases the final product may be further modified, for example, by manipulation of substituents to give a new final product. These manipulations may include, but are not limited to, reduction, oxidation, alkylation, acylation, hydrolysis and transition-metal catalysed cross-coupling reactions which are commonly known to those skilled in the art.

A.1. Synthesis of pyrimidine halide derivatives of formula (III)

A.1.1. 6-Chloro-N-(2-(2-methyl-1 H-indol-1-yl)ethyl)pyrimidin-4-amine

To a solution of 4,6-dichloropyrimidine (3.00 g, 20.1 mmol) in 2-propanol (50 mL) at RT is added 2-(2-methyl-1 H- indol-1-yl)ethan-1-amine (3.68 g, 21.1 mmol) and TEA (3.08 mL, 22.2 mmol). The resulting mixture is refluxed for 2h, then allowed to cool to RT and concentrated under reduced pressure. The residue is partitioned between sat. aq. NaHC03 solution and EtOAc. The layers are separated and the aqueous layer is extracted once more with EtOAc. The combined organic layers are washed with water, brine, dried over MgS04, filtered and the solvent is removed in vacuo yielding the desired product as a yellow powder (5.45 g, 94%). LC-MS A: t = 0.87 min; [M+H] ⁺ = 287.13. A.1.1.1. 2-(2-Methyl-1 H-indol-1-yl)ethan-1-amine

To a solution of 2-methylindole (10.04 g, 75 mmol) in toluene (200 mL) are added 2-chloroethylamine hydrochloride (17.4 g, 150 mmol), freshly powdered NaOH (21.00 g, 525 mmol) and tetrabutyl ammonium hydrogen sulfate (2.037 g, 6 mmol). The resulting mixture is heated up to reflux and stirred for 17h. It is then cooled down to RT, and filtered through a filter paper. The residue is triturated twice with toluene, and filtrated. The filtrate is concentrated under reduced pressure, and the residue is purified by FC, using a gradient of DCM/MeOH from 100:0 to 95:5. After concentration of the product containing fractions, the title compound (13.2 g, 99%) is obtained as a yellow resin: LC-MS A: t _R = 0.54 min; [M+H] ⁺ = 175.31.
