     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to new antagonists of adenosine receptors, in particular antagonist of the A 2A  adenosine receptor subtype, the use of said compounds in the treatment of diseases, and disorders susceptible of being ameliorated by antagonism of adenosine receptors, in particular in the treatment of disorders of the central nervous system which are known to be improved by the use of antagonists of the A 2A  adenosine receptors, more specifically movement disorders such as Parkinson&#39;s disease, restless leg syndrome and dyskinesia and to pharmaceutical compositions comprising said compounds. 
         [0004]    2. Description of the Related Art 
         [0005]    The effects of adenosine are mediated through at least four specific cell membrane receptors so far identified and classified as receptors A 1 , A 2A , A 2B  and A 3  belonging to the G protein-coupled receptor family. The A 1  and A 3  receptors down-regulate cellular cAMP levels through their coupling to G proteins, which inhibit adenylate cyclase. In contrast, A 2A  and A 2B  receptors couple to G proteins that activate adenylate cyclase and increase intracellular levels of cAMP. Through these receptors, adenosine regulates a wide range of physiological functions. 
         [0006]    Thus, in the cardiovascular system the activation of the A 1  receptor protects cardiac tissue from the effects of ischemia and hypoxia. A similar protective effect is also produced by antagonism of the A 2A  receptor, which enhances A 1 -receptor-induced antiadrenergic responses and may also be useful in the treatment of acute myocardial ischemia and supraventricular arrhythmias (Norton G R et al.  Am J Physiol.  1999; 276(2 Pt 2):H341-9; Auchampach J A, Bolli R.  Am J Physiol.  1999; 276(3 Pt 2):H1113-6). In addition, the A 2B  adenosine receptor subtype (Feoktistov, I. et al.,  Pharmacol. Rev.  1997, 49, 381-402) appears to be involved in the control of vascular tone and the regulation of vascular smooth muscle growth. 
         [0007]    In the kidney, adenosine exerts a biphasic action, inducing vasodilation at high concentrations and vasoconstriction at low concentrations. Thus, adenosine plays a role in the pathogenesis of some forms of acute renal failure that may be ameliorated by A 1  receptor antagonists (Costello-Boerrigter L C, et al.  Med Clin North Am.  2003 March; 87(2): 475-91; Gottlieb S S., Drugs. 2001; 61(10): 1387-93). 
         [0008]    Adenosine is also involved in the physiopathology of the immune system. It can induce degranulation of activated human mast cells through the A 2B  and/or A 3  receptor. Thus A 2B  and/or A 3  antagonists prevent mast cell degranulation and are, therefore, useful in the treatment, prevention or suppression of disease states induced by activation of the A 2B  and/or A 3  receptor and mast cell degranulation. These disease states include but are not limited to asthma, myocardial reperfusion injury, allergic reactions including but not limited to rhinitis, urticaria, scleroderm arthritis, other autoimmune diseases and inflammatory bowel diseases. 
         [0009]    Furthermore, in the respiratory system adenosine induces bronchoconstriction, modulates airway inflammation and promotes neutrophil chemotaxis. Therefore, an adenosine antagonist would be particularly useful in the treatment of asthma. 
         [0010]    In the gastrointestinal and metabolic system, the A 2B  adenosine receptor subtype (Feoktistov, I. et al.,  Pharmacol. Rev.  1997, 49, 381-402) seems to be involved in the regulation of hepatic glucose production, the modulation of intestinal tone, as well as intestinal secretion. Thus, A 2B  antagonists may also be useful in the treatment of diabetes mellitus and obesity. 
         [0011]    In the central nervous system adenosine is a potent endogenous neuromodulator, which controls the presynaptic release of many neurotransmitters and is thus involved in motor function, sleep, anxiety, pain and psychomotor activity. All adenosine receptor subtypes are present in the brain, with A 1  and A 2A  subtypes being differentially distributed. The former are found predominantly in the hippocampus and cortex, whilst the latter are found mainly in the striatum. Adenosine A 2A  receptors modulate the release of GABA in the striatum, which possibly regulates the activity of medium spiny neurons. 
         [0012]    Thus, A 2A  receptor antagonists may be a useful treatment for neurodegenerative movement disorders such as Parkinson and Huntington&#39;s disease (Tuite P, et al.,  J. Expert Opin Investig Drugs.  2003; 12: 1335-52; Popoli P. et al.  J. Neurosci.  2002; 22:1967-75), dystonias such as restless leg syndrome (Happe S, et al.,  Neuropsychobiology.  2003; 48: 82-6), and dyskinesias such as those caused by prolonged use of neuroleptic and dopaminergic drugs (Jenner P.  J Neurol.  2000; 247 Suppl 2: II43-50). 
         [0013]    In the treatment of Parkinson&#39;s disease an A 2A  antagonist may be useful not only as monotherapy, but also when administered in combination with L-DOPA and/or one or more of the following drugs: dopamine agonists, inhibitors of dopamine decarboxylase, catechol-O-methyltransferase inhibitors and inhibitors of monoamine oxidase. 
         [0014]    In addition, A 2A  antagonists may have therapeutic potential as neuroprotectants (Stone T W. et al.,  Drug. Dev. Res.  2001; 52: 323-330), and in the treatment of sleep disorders (Dunwiddie T V et al.,  Ann. Rev. Neurosci.  2001; 24: 31-55). 
         [0015]    It has now been found that certain 4-aminopyrimidine derivatives are novel potent antagonists of the A 2A  adenosine receptor and can therefore be used in the treatment or prevention of diseases susceptible to amelioration by antagonism of the adenosine receptor. 
         [0016]    Further objectives of the present invention are to provide a method for preparing said compounds; pharmaceutical compositions comprising an effective amount of said compounds; the use of the compounds in the manufacture of a medicament for the treatment of pathological conditions or diseases susceptible of being improved by antagonism of an adenosine receptor, in particular by antagonism of the A 2A  adenosine receptor; methods of treatment of pathological conditions or diseases susceptible to amelioration by antagonism of an adenosine receptor, in particular by antagonism of the A 2A  adenosine receptor comprising the administration of the compounds of the invention to a subject in need of treatment and combinations of said compounds with one or more of the following drugs: L-DOPA, dopamine agonists, inhibitors of dopamine decarboxylase, catechol-O-methyltransferase inhibitors and inhibitors of monoamine oxidase.

         [0554]    The carboxyamidines of formula (II), wherein R 1  is a monocyclic or polycyclic heteroaryl group linked to the carboxyamidine group through a carbon atom can be obtained by reacting a nitrile of formula (XXXI) with trimethylaluminum and ammonium chloride, in a solvent such as benzene, toluene or xylene, at a temperature from 80° to 120° C. It also can be obtained by reaction of a nitrile of formula (XXXI) with sodium methoxide in methanol at room temperature, followed by reaction with ammonium chloride at the same temperature. 
         [0555]    The carboxyamidines of formula (II) can be reacted with diethyl malonate in a solvent such as methanol, ethanol, isopropyl alcohol, butyl alcohol or tetrahydrofuran, in the presence of a base, such as sodium methoxide, sodium ethoxide or potassium tertbutoxide and at a temperature from room temperature to the boiling point of the solvent to yield the pyrimidine-4,6-diols of formula (III). 
         [0556]    The resulting pyrimidine-4,6-diols of formula (III) can be reacted with a chlorinated agent such a phosphorus oxychloride, phosphorus pentachloride or a mixture of them, in a solvent such as phosphorus oxychloride, benzene or toluene, at a temperature from room temperature to the boiling point of the solvent to yield the 4,6-dichloropyrimidine compounds of formula (IV). Optionally, the presence of a base such as dimethylaminoaniline, triethylamine or diisopropyl-ethylamine may be needed in this reaction step. 
         [0557]    The reaction of the 4,6-dichloropyrimidine compounds of formula (IV) with ammonium hydroxide in a solvent such as methanol, ethanol, isopropyl alcohol or tetrahydrofuran, at a temperature from 80° to 140° C. produces the 6-chloropyrimidin-4-amines of formula (V). 
         [0558]    The resulting the 6-chloropyrimidin-4-amines of formula (V) are reacted with a compound of formula R 2 —H wherein R 2  is a monocyclic or polycyclic heteroaryl group linked to the pyrimidine ring through a nitrogen atom to yield the compounds of formula (VIIIa) which is a particular case of the compounds of formula (I) according to the invention. The reaction is carried out in a solvent such as dimethylformamide, dimethylacetamide or dimethylsulfoxide, in the presence of a base, such as sodium hydride, potassium carbonate or cesium carbonate, at a temperature from 60° to 140° C. 
         [0559]    The compounds of formula (VIIIa) can be acylated by an acid chloride and a base, such as pyridine, triethylamine or diisopropylethylamine, in a solvent such as tetrahydrofuran, methylene chloride, chloroform or pyridine, at a temperature from room temperature to the boiling point of the solvent to yield the compounds of formula (IXa) which is a particular case of the compounds of formula (I) according to the invention. Compounds of formula (IXa) can also be prepared by reaction of amine (VIIIa) with an anhydride, at a temperature from 80° to 160° C. 
         [0560]    The 4,6-dichloropyrimidine compounds of formula (IV) can also be converted into the 4-chloropyrimidines of formula (Xa) by reaction with a compound of formula R 2 —H wherein R 2  is a monocyclic or polycyclic heteroaryl group linked to the pyrimidine ring through a nitrogen atom. The reaction is carried out in a solvent such as dimethylformamide, dimethylacetamide or dimethylsulfoxide, in the presence of a base, such as sodium hydride, potassium carbonate or cesium carbonate, at a temperature from 60° to 140° C. 
         [0561]    The resulting 4-chloropyrimidines of formula (Xa) can then be converted to the compounds of formula (VIIIa) according to the invention by reaction with ammonium hydroxide in a solvent such as methanol, ethanol, isopropyl alcohol or tetrahydrofuran, at a temperature from 80° C. to 140° C. 
         [0562]    Alternatively, the compounds of formula (VIIIa) according to the invention can also be obtained from the compounds of formula (IXa) by reaction with a mineral acid, such as hydrochloric acid or sulphuric acid, in a solvent such as water, methanol, ethanol or isopropyl alcohol, at a temperature from room temperature to the boiling point of the solvent. 
         [0563]    The compounds of formula (IXa) according to the invention can be obtained by reaction of the compounds of formula (XII) with compounds of formula R 2 H wherein R 2  is as hereinabove-defined. The reaction is carried out in a solvent such as dimethylformamide, dimethylacetamide or dimethylsulfoxide, in the presence of a base, such as sodium hydride, potassium carbonate or cesium carbonate, at a temperature from 60° to 140° C. 
         [0564]    The compounds of formula (XII) can be obtained from the 6-aminopyrimidin-4-ol compounds of formula (VI) by reaction with a carboxylic acid of formula R 3 COOH, wherein R 3  is as hereinabove-defined in the presence of a chlorinated agent such as phosphorus oxychloride, phosphorus pentachloride or thionyl chloride, at a temperature from 60° to 120° C. 
         [0565]    The 6-aminopyrimidin-4-ol compounds of formula (VI) are in turn obtained by reaction of the carboxyamidines of formula (II) with ethylcyanoacetate.

       Pharmacological Activity 
     Adenosine A 2A  Receptor Binding Assays 
     Receptor Cloning 
       [0600]    The coding sequence of the human A 2A  receptor was amplified from a human brain cDNA library by the polymerase chain reaction. The amplicon was cloned into the pcDNA5/FRT/V5-His-TOPO expression vector (Invitrogen) and sequence confirmed using an ABI 3100 automated sequencer (Applied Biosystems). The expression construct was transfected into Flp-In HEK cells (Invitrogen) using Lipofectamine 2000 (Invitrogen). Cells stably expressing the human A 2A  receptor were selected using 1 mg/ml hygromycin in complete DMEM. 
       Membrane Preparation 
       [0601]    Crude membranes were prepared from Flp-In HEK cells transfected with the human A 2A  receptor by resuspending cells in lysis buffer (50 mM Tris-HCl pH 7.4, 5 mM EDTA, 10 mM MgCl 2 ) and disrupting under N 2  at a pressure of 900 psi (Parr Cell disruption bomb, cat.4639) for 30 min on ice followed by differential centrifugation. The resulting crude membrane pellet was resuspended in assay buffer (50 mM Tris HCl pH 7.4, 1 mM EDTA, 10 mM MgCl 2 ). Membrane protein concentration was determined by Bradford assay and aliquots were stored at −80° C. 
       Binding Assay 
       [0602]    An aliquot of membranes (5-10 μg of protein) was pre-incubated for 30 min at RT in the presence of 10 μg/ml Adenosine Deaminase (Type IV Calf Spleen, Sigma). Membranes were then incubated for 90 min with 1.0 nM [ 3 H]-ZM 241385 (27.40 Ci/mmol Tocris R1036) in the presence of varying concentrations of competing ligand. Non-specific binding was determined in the presence of excess (1 μM) of CGS15943. Bound and free ligand were separated by rapid vacuum filtration using a Packard 96-well cell harvester onto UniFilter GF/C filter plates (PerkinElmer) that had been pretreated with 0.5% polyethyleneimine. The filter plates were than washed 3×200 μl with 50 mM Tris HCl, 50 mM NaCl pH 7.4. Bound radioligand was determined by scintillation counting using a TopCount-NXT (Packard). Binding data was analyzed by nonlinear, least-squares curve fitting algorithms using GraphPad Prism (GraphPad Software, Inc. San Diego, Calif.) or ActivityBase (IDBS, Guildford, Surrey, UK). K i  values were calculated from IC 50  values using the Cheng-Prusoff equation (Cheng, Y, Prusoff, W.H. Biochem. Pharm. 22:3099-3108, 1973.). 
         [0603]    For A 2A  membrane assay: 
         [0000]    ZM241385 measured Kd=0.3±0.2 nM; B max =33±8 pmol/mg by Scatchard Analysis Binding Ki=0.25±0.04 nM. 
         [0604]    With reference to A 2A  receptor binding affinities, A 2A  receptor antagonists of this invention may have a IC 50  of less than 10 μM. In one embodiment of this invention, a A 2A  receptor antagonist has a IC 50  of less than 1 μM. In another embodiment the IC 50  is less than 0.25 μM (i.e., 250 nM).

         [0665]    To 20 mL dichloromethane were added 1.4 g (5.4 mM, M.W. 258) Intermediate 11 and 0.56 mL (1.3 eq) pyridine. Acryloyl chloride (0.6 mL, 0.64 g, 1.3 eq) was added drop-wise and the reaction mixture was stirred at room temperature for 1 hour. The reaction was quenched with 50 mL saturated sodium bicarbonate and extracted with 50 mL dichloromethane. The product stayed in aqueous solution. The aqueous solution was concentrated to dryness and resuspended in 15 mL DMF and 15 mL EtOH. The mixture was filtered, and the filtrate was concentrated. The solid thus obtained was used for library synthesis without further purification. The solid was dissolved in 1/1 DMF/EtOH, added 2-eq amine and stirred at room temperature overnight. Purified by either TLC plates or Prep LC-MS. 
         [0666]    The compounds of Table 2B were prepared by reacting intermediate 12B with the appropriate amine.

         [0788]    To a solution of Intermediate 4 (1.0 g, 5.1 mmol) in absolute EtOH (4.5 mL) was added anhydrous hydrazine (0.32 mL, 10.2 mmol). The mixture was heated at 90° C. for 22 hours. The reaction was then cooled to room temperature and placed in an ice bath at 0° C. while 2,4-pentanedione (1.05 mL, 10.2 mmol) was added slowly. The reaction mixture was heated at 90° C. for 2 hours. Upon consumption of the hydrazine intermediate, the reaction was evaporated completely. The crude mixture was dissolved in CH 2 Cl 2  (50 mL) and water (25 mL). The layers were separated and the aqueous layer was extracted with CH 2 Cl 2  (4×25 mL). The combined organic layers were washed with brine (25 mL), dried over magnesium sulfate, filtered, and concentrated. The crude product was purified by flash chromatography using 1:1 EtOAc/Hexanes to give the 0.94 g (3.68 mmol, 72%) of Intermediate 30 as a white solid.

         [0827]    A slurry of Intermediate 19C (0.27 g, 1.0 mmol) and NaH (40 mg, 1 eq) in DMF/THF (1/1, 2 mL) was stirred until the evolution of H 2  had ceased (10 min). The resulting solution was slowly stirred into a solution of CDI (0.17 g, 1 eq) in DMF (1 mL). Alter 10 min, 1-methyl-piperazine (0.11 mL, 1 eq) was added and the mixture was stirred for 4 hr.
