4 - [CYCLOALKYLOXY (HETERO) ARYLAMINO] THIENO [2 , 3 - D] PYRIMIDINES HAVING MNKl/ MNK2 INHIBITING ACTIVITY FOR PHARMACEUTICAL COMPOSITIONS

The present invention relates to thienopy midine compounds and to novel pharmaceutical compositions comprising thienopyhmidine compounds.

Moreover, the present invention relates to the use of the thienopyhmidine compounds of the invention for the production of pharmaceutical compositions for the prophylaxis and/or treatment of diseases which can be influenced by the inhibition of the kinase activity of Mnk1 (Mnk1 a or MnK1 b) and/or Mnk2 (Mnk2a or Mnk2b) or further variants thereof. Particularly, the present invention relates to the use of the thienopyhmidine compounds of the invention for the production of pharmaceutical compositions for the prophylaxis and/or therapy of metabolic diseases, such as diabetes, hyperlipidemia and obesity, hematopoietic disorders, neurodegenerative diseases, kidney damage, inflammatory disorders, and cancer and their consecutive complications and disorders associated therewith.

Metabolic diseases are diseases caused by an abnormal metabolic process and may either be congenital due to an inherited enzyme abnormality or acquired due to a disease of an endocrine organ or failure of a metabolically important organ such as the liver or the pancreas.

The present invention is more particularly directed to the treatment and/or

prophylaxis of in particular metabolic diseases of the lipid and carbohydrate

metabolism and the consecutive complications and disorders associated therewith.

Lipid disorders cover a group of conditions which cause abnormalities in the level and metabolism of plasma lipids and lipoproteins. Thus, hyperlipidemias are of particular clinical relevance since they constitute an important risk factor for the development of atherosclerosis and subsequent vascular diseases such as coronary heart disease.

Diabetes mellitus is defined as a chronic hyperglycemia associated with resulting damages to organs and dysfunctions of metabolic processes. Depending on its etiology, one differentiates between several forms of diabetes, which are either due to an absolute (lacking or decreased insulin secretion) or to a relative lack of insulin. Diabetes mellitus Type I (IDDM, insulin-dependent diabetes mellitus) generally occurs in adolescents under 20 years of age. It is assumed to be of auto-immune etiology, leading to an insulitis with the subsequent destruction of the beta cells of the islets of Langerhans which are responsible for the insulin synthesis. In addition, in latent autoimmune diabetes in adults (LADA; Diabetes Care. 8: 1460-1467, 2001 ) beta cells are being destroyed due to autoimmune attack. The amount of insulin produced by the remaining pancreatic islet cells is too low, resulting in elevated blood glucose levels (hyperglycemia). Diabetes mellitus Type II generally occurs at an older age. It is above all associated with a resistance to insulin in the liver and the skeletal muscles, but also with a defect of the islets of Langerhans. High blood glucose levels (and also high blood lipid levels) in turn lead to an impairment of beta cell function and to an increase in beta cell apoptosis.

Diabetes is a very disabling disease, because today's common anti-diabetic drugs do not control blood sugar levels well enough to completely prevent the occurrence of high and low blood sugar levels. Out of range blood sugar levels are toxic and cause long-term complications for example retinopathy, Tenopathy, neuropathy and peripheral vascular disease. There is also a host of related conditions, such as obesity, hypertension, heart disease and hyperlipidemia, for which persons with diabetes are substantially at risk.

Obesity is associated with an increased risk of follow-up diseases such as

cardiovascular diseases, hypertension, diabetes, hyperlipidemia and an increased mortality. Diabetes (insulin resistance) and obesity are part of the "metabolic syndrome" which is defined as the linkage between several diseases (also referred to as syndrome X, insulin-resistance syndrome, or deadly quartet). These often occur in the same patients and are major risk factors for development of diabetes type II and cardiovascular disease. It has been suggested that the control of lipid levels and glucose levels is required to treat diabetes type II, heart disease, and other occurrences of metabolic syndrome (see e.g., Diabetes 48: 1836-1841 , 1999; JAMA 288: 2209-2716, 2002).

In one embodiment of the present invention the compounds and compositions of the present invention are useful for the treatment and/or prophylaxis of metabolic diseases of the carbohydrate metabolism and their consecutive complications and disorders such as impaired glucose tolerance, diabetes (preferably diabetes type II), diabetic complications such as diabetic gangrene, diabetic arthropathy, diabetic osteopenia, diabetic glomerosclerosis, diabetic nephropathy, diabetic dermopathy, diabetic neuropathy, diabetic cataract and diabetic retinopathy, diabetic maculopathy, diabetic feet syndrome, diabetic coma with or without ketoacidosis, diabetic hyperosmolar coma, hypoglycemic coma, hyperglycemic coma, diabetic acidosis, diabetic ketoacidosis, intracapillary glomerulonephrosis, Kimmelstiel-Wilson syndrome, diabetic amyotrophy, diabetic autonomic neuropathy, diabetic

Certain anti-cancer drugs such as cisplatin are linked to serious side effects such as nephrotoxicity or ototoxicity, which can be dose limiting. Activation of Mnks has been linked to these side effects. In a further embodiment of the present invention, the compounds and compositions of the present invention are useful for the treatment and/or prophylaxis of ear or kidney damage, in particular for the prevention or treatment of ear and kidney drug induced damage Furthermore, the present invention relates to the use of thienopyrimidine compounds for the production of pharmaceutical compositions for the prophylaxis and/or therapy of cytokine related diseases.

Such diseases are i.a. inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, infectious diseases, neurodegenerative diseases, allergies, or other conditions associated with proinflammatory cytokines. Allergic and inflammatory diseases such as acute or chronic inflammation, chronic inflammatory arthritis, rheumatoid arthritis, psoriasis, COPD, inflammatory bowel disease, asthma and septic shock and their consecutive complications and disorders associated therewith.

Inflammatory diseases like rheumatoid arthritis, inflammatory lung diseases like COPD, inflammatory bowel disease and psoriasis afflict one in three people in the course of their lives. Not only do those diseases impose immense health care costs, but also they are often crippling and debilitating.

Although inflammation is the unifying pathogenic process of these inflammatory diseases below, the current treatment approach is complex and is generally specific for any one disease. Many of the current therapies available today only treat the symptoms of the disease and not the underlying cause of inflammation.

The compositions of the present invention are useful for the treatment and/or prophylaxis of inflammatory diseases and consecutive complications and disorders, such as chronic or acute inflammation, inflammation of the joints such as chronic inflammatory arthritis, rheumatoid arthritis, psoriatic arthritis, osteoarthritis, juvenile rheumatoid arthritis, Reiter's syndrome, rheumatoid traumatic arthritis, rubella arthritis, acute synovitis and gouty arthritis; inflammatory skin diseases such as sunburn, psoriasis, erythrodermic psoriasis, pustular psoriasis, eczema, dermatitis, acute or chronic graft formation, atopic dermatitis, contact dermatitis, urticaria and scleroderma; inflammation of the gastrointestinal tract such as inflammatory bowel disease, Crohn ^' s disease and related conditions, ulcerative colitis, colitis, and diverticulitis; nephritis, urethritis, salpingitis, oophoritis, endomyometritis, spondylitis, systemic lupus erythematosus and related disorders, multiple sclerosis, asthma, meningitis, myelitis, encephalomyelitis, encephalitis, phlebitis, thrombophlebitis, respiratory diseases such as asthma, bronchitis, chronic obstructive pulmonary disease (COPD), inflammatory lung disease and adult respiratory distress syndrome, and allergic rhinitis; endocarditis, osteomyelitis, rheumatic fever, rheumatic

spondoarthropathies ankylosing spondylitis, synovitis, tenosynovotis, myositis, pharyngitis, polymyalgia rheumatica, shoulder tendonitis or bursitis, gout, pseudo gout, vasculitides, inflammatory diseases of the thyroid selected from granulomatous thyroiditis, lymphocytic thyroiditis, invasive fibrous thyroiditis, acute thyroiditis;

Hashimoto ^' s thyroiditis, Kawasaki ^' s disease, Raynaud ^' s phenomenon, Sjogren ^' s syndrome, neuroinflammatory disease, sepsis, conjunctivitis, keratitis, iridocyclitis, optic neuritis, otitis, lymphoadenitis, nasopaharingitis, sinusitis, pharyngitis, tonsillitis, laryngitis, epiglottitis, bronchitis, pneumonitis, stomatitis, gingivitis, oesophagitis, gastritis, peritonitis, hepatitis, cholelithiasis, cholecystitis, glomerulonephritis, goodpasture ^' s disease, crescentic glomerulonephritis, pancreatitis, endomyometritis, myometritis, metritis, cervicitis, endocervicitis, exocervicitis, parametritis,

tuberculosis, vaginitis, vulvitis, silicosis, sarcoidosis, pneumoconiosis, pyresis, inflammatory polyarthropathies, psoriatric arthropathies, intestinal fibrosis,

bronchiectasis and enteropathic arthropathies.

Moreover, cytokines are also believed to be implicated in the production and development of various cardiovascular and cerebrovascular disorders such as congestive heart disease, myocardial infarction, the formation of atherosclerotic plaques, hypertension, platelet aggregation, angina, stroke, Alzheimer's disease, reperfusion injury, vascular injury including restenosis and peripheral vascular disease, and, for example, various disorders of bone metabolism such as

osteoporosis (including senile and postmenopausal osteoporosis), Paget's disease, bone metastases, hypercalcaemia, hyperparathyroidism, osteosclerosis,

osteoporosis and periodontitis, and the abnormal changes in bone metabolism which may accompany rheumatoid arthritis and osteoarthritis.

Excessive cytokine production has also been implicated in mediating certain complications of bacterial, fungal and/or viral infections such as endotoxic shock, septic shock and toxic shock syndrome and in mediating certain complications of CNS surgery or injury such as neurotrauma and ischaemic stroke. Excessive cytokine production has, moreover, been implicated in mediating or exacerbating the development of diseases involving cartilage or muscle resorption, pulmonary fibrosis, cirrhosis, renal fibrosis, the cachexia found in certain chronic diseases such as malignant disease and acquired immune deficiency syndrome (AIDS), tumour invasiveness and tumour metastasis and multiple sclerosis. The treatment and/or prophylaxis of these diseases are also contemplated by the present invention

Additionally, the inventive compositions may be used to treat inflammation

associated with autoimmune diseases including, but not limited to, systemic lupus erythematosis, Addison's disease, autoimmune polyglandular disease (also known as autoimmune polyglandular syndrome), glomerulonephritis, rheumatoid arthritis scleroderma, chronic thyroiditis, Graves' disease, autoimmune gastritis, diabetes, autoimmune hemolytic anemia, glomerulonephritis, rheumatoid arthritis autoimmune neutropenia, thrombocytopenia, atopic dermatitis, chronic active hepatitis,

myasthenia gravis, multiple sclerosis, inflammatory bowel disease, ulcerative colitis, Crohn's disease, psoriasis, and graft vs. host disease.

In a further embodiment the compositions of the present invention may be used for the treatment and prevention of infectious diseases such as sepsis, septic shock, Shigellosis, and Helicobacter pylori and viral diseases including herpes simplex type 1 (HSV-1 ), herpes simplex type 2 (HSV-2), cytomegalovirus, Epstein-Barr, human immunodeficiency virus (HIV), acute hepatitis infection (including hepatitis A, hepatits B, and hepatitis C), HIV infection and CMV retinitis, AIDS or malignancy, malaria, mycobacterial infection and meningitis. These also include viral infections, by influenza virus, varicella-zoster virus (VZV), Epstein-Barr virus, human herpesvirus-6 (HHV-6), human herpesvirus-7 (HHV-7), human herpesvirus-8 (HHV-8), Poxvirus, Vacciniavirus, Monkeypoxvirus, pseudorabies and rhinotracheitis.

Periodontal disease has also been implemented in cytokine production, both topically and systemically. Hence, use of compositions of the present invention to control the inflammation associated with cytokine production in such peroral diseases such as gingivitis and periodontitis is another aspect of the present invention.

Finally, the compositions of the present invention may also be used to treat or prevent neurodegenerative disease selected from Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, frontotemporal lobar dementia, spinocerebellar ataxia, dementia with Lewy bodies, cerebral ischemia or neurodegenerative disease caused by traumatic injury, glutamate neurotoxicity or hypoxia.

Protein kinases are important enzymes involved in the regulation of many cellular functions. The LK6-serine/threonine-kinase gene of Drosophila melanogaster was described as a short-lived kinase which can associate with microtubules (J. Cell Sci. 1997, 1 10(2): 209-219). Genetic analysis in the development of the compound eye of Drosophila suggested a role in the modulation of the RAS signal pathway (Genetics 2000 156(3): 1219-1230). The closest human homologues of Drosophila LK6-kinase are the MAP-kinase interacting kinase 2 (Mnk2, e.g. the variants Mnk2a and Mnk2b) and MAP-kinase interacting kinase 1 (Mnk1 ) and variants thereof. These kinases are mostly localized in the cytoplasm. Mnks are phosphorylated by the p42 MAP kinases Erk1 and Erk2 and the p38-MAP kinases. This phosphorylation is triggered in a response to growth factors, phorbol esters and oncogenes such as Ras and Mos, and by stress signaling molecules and cytokines. The phosphorylation of Mnk proteins stimulates their kinase activity towards eukaryotic initiation factor 4E (elF4E) (EMBO J. 16: 1909-1920, 1997; Mol Cell Biol 19, 1871 -1880, 1990; Mol Cell Biol 21 , 743-754, 2001 ). Simultaneous disruption of both, the Mnk1 and Mnk2 gene in mice diminishes basal and stimulated elF4E phosphorylation (Mol Cell Biol 24, 6539-6549, 2004). Phosphorylation of elF4E results in a regulation of the protein translation (Mol Cell Biol 22: 5500-551 1 , 2001 ).

There are different hypotheses describing the mode of the stimulation of the protein translation by Mnk proteins. Most publications describe a positive stimulatory effect on the cap-dependent protein translation upon activation of MAP kinase-interacting kinases. Thus, the activation of Mnk proteins can lead to an indirect stimulation or regulation of the protein translation, e.g. by the effect on the cytosolic phospholipase 2 alpha (BBA 1488:124-138, 2000).

WO 03/037362 discloses a link between human Mnk genes, particularly the variants of the human Mnk2 genes, and diseases which are associated with the regulation of body weight or thermogenesis. It is postulated that human Mnk genes, particularly the Mnk2 variants are involved in diseases such as e.g. metabolic diseases including obesity, eating disorders, cachexia, diabetes mellitus, hypertension, coronary heart disease, hypercholesterolemia, dyslipidemia, osteoarthritis, biliary stones, cancer of the genitals and sleep apnea, and in diseases connected with the ROS defense, such as e.g. diabetes mellitus and cancer. WO 03/03762 moreover discloses the use of nucleic acid sequences of the MAP kinase-interacting kinase (Mnk) gene family and amino acid sequences encoding these and the use of these sequences or of effectors of Mnk nucleic acids or polypeptides, particularly Mnk inhibitors and activators in the diagnosis, prophylaxis or therapy of diseases associated with the regulation of body weight or thermogenesis. WO 02/103361 describes the use of kinases 2a and 2b (Mnk2a and Mnk2b) interacting with the human MAP kinase in assays for the identification of

pharmacologically active ingredients, particularly useful for the treatment of diabetes mellitus type 2. Moreover, WO 02/103361 discloses also the prophylaxis and/or therapy of diseases associated with insulin resistance, by modulation of the expression or the activity of Mnk2a or Mnk2b. Apart from peptides, peptidomimetics, amino acids, amino acid analogues, polynucleotides, polynucleotide analogues, nucleotides and nucleotide analogues, 4-hydroxybenzoic acid methyl ester are described as a substance which binds the human Mnk2 protein.

First evidence for a role of Mnks in inflammation was provided by studies

demonstrating activation of Mnk1 by proinflammatory stimuli. The cytokines TNFa and IL-1 β trigger the activation of Mnk1 in vitro (Fukunaga and Hunter, EMBO J 16(8): 1921 -1933, 1997) and induce the phosphorylation of the Mnk-specific substrate elF4E in vivo (Ueda et al ., Mol Cell Biol 24(15): 6539-6549, 2004). In addition, administration of lipopolysaccharide (LPS), a potent stimulant of the inflammatory response, induces activation of Mnk1 and Mnk2 in mice, concomitant with a phosphorylation of their substrate elF4E (Ueda et al ., Mol Cell Biol 24(15): 6539-6549, 2004).

Furthermore, Mnk1 has been shown to be involved in regulating the production of proinflammatory cytokines. Mnk1 enhances expression of the chemokine RANTES (Nikolcheva et al., J Clin Invest 1 10, 1 19-126, 2002). RANTES is a potent chemotractant of monocytes, eosinophils, basophiles and, natural killer cells. It activates and induces proliferation of T lymphocytes, mediates degranulation of basophils and induces the respiratory burst in eosinophils (Conti and DiGioacchino, Allergy Asthma Proc 22(3):133-7, 2001 )

WO 2005/00385 and Buxade et al ., Immunity 23: 177-189, August 2005 both disclose a link between Mnks and the control of TNFa biosynthesis. The proposed mechanism is mediated by a regulatory AU-rich element (ARE) in the TNFa mRNA. Buxade et al. demonstrate proteins binding and controlling ARE function to be phosphorylated by Mnk1 and Mnk2. Specifically Mnk-mediated phosphorylation of the ARE-binding protein hnRNP A1 has been suggested to enhance translation of the TNFa mRNA. TNFa is not the only cytokine regulated by an ARE. Functional AREs are also found in the transcripts of several interleukins, interferones and chemokines (Khabar, J Interf Cytokine Res 25: 1 -10, 2005). The Mnk-mediated phosphorylation of ARE- binding proteins has thus the potential to control biosynthesis of cytokines in addition to that of TNFa.

Current evidence demonstrates Mnks as down stream targets of inflammatory signalling as well as mediators of the inflammatory response. Their involvement in the production of TNFa, RANTES, and potentially additional cytokines suggests inhibition of Mnks as strategy for anti-inflammatory therapeutic intervention.

Mnk1 and Mnk2 (including all splice forms) phosphorylate the translation factor elF4E on Serine 209. Mnk1 /2 double knockout mice completely lack phosphorylation on Serine 209, indicating that Mnk kinase are the only kinases able to phosphorylate this site in vivo (Ueda et al ., Mol Cell Biol . 2004; 24(15):6539-49). elF4E is

overexpressed in a wide range of human malignancies, and high elF4E expression is frequently associated with more aggressive disease and poor prognosis.

Furthermore, elF4E can act as an oncogene when assayed in standard assays for oncogenic activity (e.g. Ruggero et al., Nat Med. 2004 May;10(5):484-6). elF4E excerts its oncogenic activity by stimulating the translation of oncogenes such as c- myc and cyclinDI (Culjkovic et al ., J Cell Biol. 2006; 175(3):415-26), by increasing the expression of pro-survival factors such as MCP-1 (Wendel et al ., Genes Dev. 2007; 21 (24):3232-7) and by positively regulating pathways of drug resistance (Wendel et al., Nature 2004; 428(6980):332-7; Graff et el., Cancer Res. 2008;

68(3):631 -4; De Benedetti and Graff, Oncogene 2004; 23(18):3189-99; Barnhart and Simon, J Clin Invest. 2007; 1 17(9):2385-8). Suppression of elF4E expression by antisense oligonucleotides has shown promise in preclinical experiments with human tumor cells (Graff et al ., J Clin Invest. 2007; 1 17(9):2638-48). It has been shown that phosphorylation on Ser209 is strictly required for the oncogenic activity of elF4E in vitro and in vivo (Topisirovic et al ., Cancer Res. 2004; 64(23):8639-42; Wendel et al ., Genes Dev. 2007; 21 (24):3232-7). Thus, inhibition of Mnkl and Mnk2 is expected to have beneficial effects in human malignancies.

Inhibitors of Mnk (referred to as CGP57380 and CGP052088) have been described (cf. Mol. Cell. Biol. 21 , 5500, 2001 ; Mol Cell Biol Res Comm 3, 205, 2000; Genomics 69, 63, 2000). CGP052088 is a staurosporine derivative having an IC ₅ o of 70 nM for inhibition of in vitro kinase activity of Mnkl . CGP57380 is a low molecular weight selective, non-cytotoxic inhibitor of Mnk2 (Mnk2a or Mnk2b) or of Mnkl : The addition of CGP57380 to cell culture cells, transfected with Mnk2 (Mnk2a or Mnk2b) or Mnkl showed a strong reduction of phosphorylated elF4E.

Further inhibitors of Mnk have been described. See for example Applicants patent applications WO 06/066937, describing pyrazolopyrimidine compounds, WO

06/136402 describing certain thienopyrimidine compounds, WO 07/1 15822 describing further thienopyrimidine compounds with modified core ring, and WO 08/006547 describing pyrrolopyrimidines as inhibitors of Mnk kinases.

The problem underlying the present invention is to provide potent and selective Mnkl and/or Mnk2 inhibitors which may effectively and safely be used for the treatment of metabolic diseases, inflammatory diseases, cancer, neurodegenerative diseases and their consecutive complication and disorders.

It has now been surprisingly found that certain thienopyrimidine compounds are potent inhibitors of the kinase enzymes Mnkl and/or Mnk2 and/or variants thereof and as such may be useful in the prophylaxis and/or therapy of diseases which can be influenced by the inhibition of the kinase activity of Mnkl and/or Mnk2 (Mnk2a or Mnk2b) and/or variants thereof.

In contrast to the thienopyrimidine compounds known in the art, for example, the compoonds disclosed in the Applicants patent applications WO 06/136402 and WO 2007/1 15822, the thienopyrimidine compounds of the present invention provide several advantages, namely, enhanced solubility, the possibility to form stable salts, improved metabolic stability, enhanced or retained activity in biochemical or cellular Mnk activity assays and enhanced or retained selectivity against other kinases.

The thienopyrimidine compounds disclosed in WO 06/136402 and WO 07/1 15822 exhibit high activity in Mnk enzyme assays and extremely high selectivity, however they show a very low solubility and are in most cases metabolic unstable resulting in undesired pharmacokinetic properties.

It has been surprisingly found that by the introduction of a polar group at the R ⁴ - position in the compounds of general formula (I) below leads to surprising substantial metabolic stabilization, rendering the thienopyrimidines of the present invention useful for in vivo pharmacological applications.

Moreover, compounds described in this application also show improved solubility, have strong inhibitory potency in biochemical and cellular assays and are highly selective, resulting in overall greatly improved pharmacological properties.

If not specified otherwise, any alkyl moiety mentioned in this application may be straight-chained or branched.

As used herein the term "metabolite" refers to (i) a product of metabolism, including intermediate and products, (ii) any substance involved in metabolism (either as a product of metabolism or as necessary for metabolism), or (iii) any substance produced or used during metabolism. In particular it refers to the end product that remains after metabolism. As used herein the term "prodrug" refers to (i) an inactive form of a drug that exerts its effects after metabolic processes within the body convert it to a usable or active form, or (ii) a substance that gives rise to a pharmacologically active metabolite, although not itself active (i.e. an inactive precursor). The terms "prodrug" or "prodrug derivative" mean a covalently-bonded derivative or carrier of the parent compound or active drug substance which undergoes at least some biotransformation prior to exhibiting its pharmacological effect(s). In general, such prodrugs have metabolically cleavable groups and are rapidly transformed in vivo to yield the parent compound, for example, by hydrolysis in blood, and generally include esters and amide analogs of the parent compounds. The prodrug is formulated with the objectives of improved chemical stability, improved patient acceptance and compliance, improved bioavailability, prolonged duration of action, improved organ selectivity, improved formulation (e.g., increased hydrosolubility), and/or decreased side effects (e.g., toxicity). In general, prodrugs themselves have weak or no biological activity and are stable under ordinary conditions. Prodrugs can be readily prepared from the parent compounds using methods known in the art, such as those described in A Textbook of Drug Design and Development,

Kinase Fluorescence Polarization Assays

Assay principle: Inhibitory potency of compounds against Mnk1 , Mnk2a and other kinases was assessed with assays based on a format known to those skilled in the art as the indirect (competitive) fluorescence polarization. The assay detection system comprises a small fluorophore-labeled phospho-peptide (termed ligand) bound to a phospho-specific antibody. The product generated by the kinase reaction competes with the ligand for antibody binding. Based on the larger molecular volume of the bound ligand, which results in a lower rotation rate in solution, its emitted light has a higher degree of polarization than the one from the free ligand.

Description of the specific homogenous kinase assay

Example 2a. Mnk1 and Mnk2a in vitro kinase assay

As a source of enzyme, human Mnk1 and human Mnk2a were expressed as GST fusion proteins in E. coli, purified to >80% homogeneity by glutathione affinity chromatography and activated in vitro with pre-activated ERK2. In brief, the open reading frames of human Mnk1 and Mnk2a were amplified from cDNA using the forward/reverse primer pairs

SEQ ID NO: 1 5TTTAGGATCCGTATCTTCTCAAAAGTTGG /

SEQ ID NO: 2 5' CTGGGTCGACTCAGAGTGCTGTGGGCGG and

SEQ ID NO: 3 5'ACAGGGATCCGTGCAGAAGAAACCAGCC / SEQ ID NO: 4 5'GATGGTCGACTCAGGCGTGGTCTCCCACC

(utilized restriction sites underlined), respectively, and cloned into the BamHI and Sail sites of the vector pGEX-4T1 (Amersham, Sweden, cat. no. 27-4580-01 ). These constructs allow prokaryotic expression of Mnk1 or Mnk2a as fusion protein with a N-terminal glutathione S-transferase (GST) tag, referred to as GST-Mnk1 or GST- Mnk2a. The following expression and purification procedure was identical for GST- Mnk1 and GST-Mnk2a, referring in general to GST-Mnk, when not distinguishing between the two isoforms. Expression of GST-Mnk was in E. coli BL21 (Merck Biosciences, Germany, cat. no. 69449). Cells were grown in LB-Bouillon (Merck, Germany, cat. no. 1 .10285) supplemented with 100 g/ml ampicillin (Sigma,

Germany, cat. no. A9518) at 37°C. When the culture had reached a density corresponding to an A ₆ oo of 0.8, an equal volume of ice cold LB/ampicillin was added, the culture transferred to 25°C and induced for 4 h with 1 mM isopropyl

thiogalactoside (IPTG, Roth, Germany, cat. no. 2316.4). Cells harvested by centrifugation were resuspended in 10 ml lysis buffer (50 mM

tris(hydroxymethyl)aminomethane hydrochloride (Tris/HCI, Sigma, Germany, cat. no. T5941 ) pH 7.5, 300 mM sodium chloride (NaCI, Sigma, Germany, cat. no. S7653), 5% (w/v) glycerol (Sigma, Germany, cat. no. G5516), 3 mM DTT dithiotreitol (DTT, Sigma, Germany, cat. no. D9779)) per gram wet weight cell pellet. Lysates were prepared by disruption of cells with a sonifier and subsequent clearing by

centrifugation at 38000 g for 45 min at 4°C.

The lysate was applied to a GSTPrep FF 16/10 column (Amersham, Sweden, cat. no. 17-5234-01 ) equilibrated with lysis buffer. Removal of unbound material was with 3 column volumes (CV) lysis buffer. Elution was with 2 CV of elution buffer (50 mM Tris/HCI pH 7.5, 300 mM NaCI, 5% (w/v) glycerol, 20 mM glutathione (Sigma, Germany, cat. no. G4251 )). Peak fractions were pooled and the protein transferred into storage buffer (50 mM Tris/HCI pH 7.5, 200 mM NaCI, 0.1 mM ethylene glycol- bis(2-aminoethylether)-N,N,N',N'-tetraacetic acid (EGTA, Aldrich, Germany, cat. no. 23,453-2), 1 mM DTT, 10% (w/v) glycerol, 0.5 M sucrose (Sigma, Germany, cat. no. S0389) by gel filtration on a PD10 desalting column (Amersham, Sweden, cat. no. 17-0851 -01 ). Aliquots were shock frozen in liquid nitrogen and stored at -80°C.

Activation of Mnk1 and Mnk2a was at a concentration of 2.5 μΜ of either purified GST-Mnk1 or GST-Mnk2a by incubation with 150 nM pre-activated NHis-ERK2 (see ERK2 assay for preparation) and 50 μΜ adenosine triphosphate (ATP, Sigma, cat. no. A2699) in a buffer comprising 20 mM N-(2-hydroxyethyl) piperazine-N'-(2- ethanesulfonic acid) (HEPES, Fluka, Germany, cat. no 54459)/potassium hydroxide (KOH, Roth, Germany, cat. no 6751 .1 ) pH 7.4, 10 mM magnesium chloride (MgCI ₂ , Sigma, Germany, cat. no. M2670), 0.25 mM DTT, 0.05% (w/v) polyoxyethylene 20 stearylether (Brij 78, Sigma, Germany, cat. no. P4019) (HMDB buffer) for 45 min at 30°C. After the incubation, the preparation was aliquoted into single-use samples, shock frozen in liquid nitrogen, stored at -80°C and utilized for Mnk1 or Mnk2a kinase assays as detailed below. The presence of activating kinase has been tested to not interfere with the Mnk activity assay.

SUBSTRATE: A carboxy-terminal amidated 12mer peptide with the sequence SEQ ID NO: 5 TATKSGSTTKNR,

derived from the amino acid sequence around serine 209 of the eukaryotic translation initiation factor 4E (elF4E) has been synthesized and purified by high performance liquid chromatography (HPLC) to >95% (Thermo, Germany). The serine residue phosphorylated by Mnk kinases is underlined.

LIGAND: The peptide TATKSG-pS-TTKNR, containing an amidated carboxy- terminus and conjugated at the amino-terminus with the oxazine derived fluorophore depicted below was synthesized and used as ligand.

ANTIBODY: SPF New Zealand White Rabbits have been immunized according to standard protocols with the peptide NH2-CTATKSG-pS-TTKNR-CONH2, coupled to keyhole limpet hemocyanin (KLH). The immune globulin G (IgG) fraction was purified from serum of boosted animals by techniques known in the art. In brief, serum was subjected to protein A affinity chromatography. Eluted material was precipitated at 50% cold saturated ammonium sulfate, pellets dissolved and desalted. The resulting material was appropriate for use in below described assay without further antigen- specific purification.

ASSAY SETUP: Inhibition of kinase activity of Mnk1 and Mnk2a was assessed with the same assay system, using pre-activated GST-Mnk1 or GST-Mnk2a, respectively. The kinase reaction contains 30 μΜ substrate peptide, 20 μΜ ATP, 60 nM ligand and one of either 25 nM pre-activated Mnk1 or 2.5 nM pre-activated Mnk2a. The reaction buffer conditions are 16 mM HEPES/KOH pH 7.4, 8 mM MgCI ₂ , 0.4 mM DTT, 0.08 % (w/v) bovine serum albumin (BSA, Sigma, Germany, cat. no. A3059), 0.008% (w/v) Pluronic F127 (Sigma, Germany, cat. no. P2443), 3% (v/v) DMSO (Applichem, Germany, cat. no. A3006). The kinase reaction is at 30°C for 40 min. The kinase reaction is terminated by addition of 0.67 reaction volumes of 1 μΜ antibody in 20 mM HEPES/KOH pH 7.4, 50 mM ethylenediaminetetraacetic acid, disodium salt (EDTA, Sigma, Germany, cat. no. E5134), 0.5 mM DTT, 0.05% (w/v)

polyoxyethylene-sorbitan monolaureate (Tween 20, Sigma, Germany, cat. no.

P7949). After 1 h equilibration time at room temperature, samples are subjected to fluorescence polarization measurement. The fluorescence polarization readout was generated on an Analyst AD multimode reader (Molecular Devices, Sunnyvale, CA, USA) equipped with a DLRP650 dichroic mirror (Omega Opticals, Brattleboro, VT, USA, cat. no. XF2035), a 630AF50 band pass filter (Omega Opticals, Brattleboro, VT, USA, cat. no. XF1069) on the excitation and a 695AF55 band pass filter on the emission side (Omega Opticals, Brattleboro, VT, USA, cat. no. XF3076). The activity of Mnk proteins can be assayed also by other in vitro kinase assay formats. For example, suitable kinase assays have been described in the literature in Knauf et al ., Mol Cell Biol. 2001 Aug;21 (16):5500-1 1 or in Scheper et al ., Mol Cell Biol . 2001 Feb;21 (3):743-54. In general, Mnk kinase assays can be performed such that a Mnk substrate such as a protein or a peptide, which may or may not include modifications as further described below, or others are phosphorylated by Mnk proteins having enzymatic activity in vitro. The activity of a candidate agent can then be determined via its ability to decrease the enzymatic activity of the Mnk protein. The kinase activity may be detected by change of the chemical, physical or immunological properties of the substrate due to phosphorylation. In one example, the kinase substrate may have features, designed or endogenous, to facilitate its binding or detection in order to generate a signal that is suitable for the analysis of the substrates phosphorylation status. These features may be, but are not limited to, a biotin molecule or derivative thereof, a glutathione-S-transferase moiety, a moiety of six or more consecutive histidine residues, an amino acid sequence or hapten to function as an epitope tag, a fluorochrome, an enzyme or enzyme fragment. The kinase substrate may be linked to these or other features with a molecular spacer arm to avoid steric hindrance.

In another example the kinase substrate may be labelled with a fluorophore. The binding of the reagent to the labelled substrate in solution may be followed by the technique of fluorescence polarization as it is described in the literature. In a variation of this example, a fluorescent tracer molecule may compete with the substrate for the analyte to detect kinase activity by a technique which is know to those skilled in the art as indirect fluorescence polarization.

In yet another example, radioactive gamma-ATP is used in the kinase reaction, and the effect of the test agent on the incorporation of radioactive phosphate in the test substrate is determined relative to control conditions.

It has been shown that the compounds of the invention exhibit low IC50 values in in vitro biological screening assays as described in example 2a for inhibition of Mnk 1 and/or Mnk 2 kinase activity. The following table contains the test results for exemplary compounds.
