Description

AMIDA THERAPEUTIC DERIVATIVES FIELD OF THE TECHNIQUE This invention relates to amide derivatives and processes for their preparation, to intermediates used in their preparation, to compositions containing them and to the uses of such derivatives.
BACKGROUND OF THE INVENTION The amide derivatives of the present invention are antagonists of the NMDA NR2B receptor (N-metii-D-aspartate), and have various therapeutic applications, particularly in the treatment of pain, stroke, traumatic brain injury, Parkinson's disease, Alzheimer's, depression, anxiety, migraine or similar. Glutamate has a double role in the central nervous system (CNS) as an essential amino acid and as a principal excitatory neutrotransmitter. There are two main classes of receptors, ionotropic and metabotropic. The ionotropic receptors are classified into three main subclasses, N-methyl-aspartate (NMDA), 2-amino-3- (methyl-3-hydroxyisoxazol-4-yl) propionic acid (AMPA) and kainate. There is considerable preclinical evidence that hyperalgesia and allodynia subsequent to lesions in peripheral tissues or nerves are not only due to an increased sensitivity of the primary afferent nociceptors at the site of injury, but also depend on mid-central changes by the NMDA receptor in synaptic excitability. In humans, it has also been discovered that NMDA receptor antagonists reduce color perception and sensitization. In addition, overactivation of the NMDA receptor is a key event to induce the death of neuronal cells under pathological conditions of acute and chronic forms of neurodegeneration. However, although inhibition of the NMDA receptor has therapeutic utility in the treatment of pain and neurodegenerative diseases, there are significant susceptibilities to many available NMDA receptor antagonists that can produce potentially serious minority effects. The NMDA subunits are distributed differentially in the CNS. Especially, it is believed that NR2B is restricted to the forebrain and laminae I and II of the dorsal horn. The more discrete distribution of the NR2B subunit in the CNS may sustain a profile of fewer minority effects of agents that act selectively at this site. For example, selective NMDA NR2B antagonists may have clinical utility for the treatment of neuropathic pain and other pain states in humans with a reduced side-effect profile compared to existing NMDA antagonists (S. Boyce, et al., Neuropharmacology, 38, p.611-623 (1999)).
International Patent Application No. (WO) 0208928 describes a variety of benzamide compounds, which are NMDA NR2B antagonists, for example, the compound (i) shown below: Compound (i) shows an IC50 of < 3 mM in the HERG potassium channel. W09967203 discloses cyclohexyl derivatives which, as claimed, are useful in the treatment of pain. There is a need to provide novel NMDA NR2B antagonists that are good drug candidates. In particular, the preferred compounds must be potently linked to the NR2B receptor and show functional activity as antagonists while showing little affinity for other receptors. They must be well absorbed from the gastrointestinal tract, must be metabolically stable and must possess favorable pharmacokinetic properties. They must be non-toxic and show few side effects. In addition, the ideal drug candidate will exist in a physical form that is stable, non-hygroscopic and easily formulated. In particular, it would be desirable to provide a selective NMDA NR2B antagonist with reduced activity in the potassium channel HERG.

A suitable sub-formula of the compounds of formula (I) can be represented by the formula (la) or a pharmaceutically acceptable salt or solvate thereof, wherein: R1A, R2A or R3A are independently selected from hydrogen, halogen, C1-6 alkyl, C-? 6 alkoxy, C-? 6 haloalkyl or C3-cycloalkyl; XA is hydrogen or hydroxy; Y is oxy, an alkylene group of 1 to 4 members, an alkylene ether group of 2 to 4 members or an oxyethyleneoxy group; and ZA is C or N. The pharmaceutically acceptable salts of the compounds of formula (I) include the basic salts thereof. Suitable basic salts are formed from bases that form non-toxic salts. Examples include the aluminum, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine and zinc salts. As a reference for suitable salts, see "andbook of Pharmaceutical Salts: Properties, Selection and Use" by Stahl and Wermuth, (Wiley-VCH, Weinheim, Germany, 2002) A pharmaceutically acceptable salt of a compound of formula (I) can be prepared easily mixing solutions of the compound of formula (I) and the desired base, as appropriate.The salt can be precipitated in the solution and collected by filtration or recovered by evaporation of the solvent.The degree of ionization can vary from completely ionized or almost non-ionized The compounds of the invention can exist in both unsolvated and solvated forms.The term "solvate" is used herein to describe a molecular complex comprising the compound of the invention and one or more pharmaceutically acceptable solvent molecules, for example The term "hydrate" is used when said solvent is water, and complexes are also within the scope of the invention. or the clathrates, drug-host molecule inclusion complexes where, in contrast to the solvates mentioned above, the drug and the host molecule are present in stoichiometric or non-stoichiometric amounts. Also included are drug complexes containing two or more organic and / or inorganic components, which may be in stoichiometric or non-stoichiometric amounts. The resulting complexes can be ionized, partially ionized or non-ionized. For a review of such complexes see J Pharm Sci, 64 (8), 1269-1288 of Haleblian (August 1975). Hereinafter, all references to compounds of formula (I) include reference to salts, solvates and complexes thereof and to solvates and complexes of the salts thereof. The compounds of the present invention include compounds of formula (I) as defined hereinabove, polymorphs, prodrugs and isomers thereof (including optical, geometric and tautomeric isomers) as defined hereafter in this document, and compounds of the formula (I) labeled with isotopes.
As indicated, the invention includes all polymorphs of the compounds of formula (I) as defined hereinabove. The so-called "prodrugs" of the compounds of formula (I) are also within the scope of the invention. Thus, certain derivatives of compounds of formula (I) which may have little or no pharmacological activity per se may, when administered in or on the body, give rise to compounds of formula (I) having the desired activity, for example, by hydrolytic cleavage. Such derivatives are referred to as "prodrugs". Additional information on the use of prodrugs can be found in "Pro-drugs as Novel Delivery Systems, Vol. 14, ACS Symposium Series (T Higuchi and W Stella) and" Bioreversible Carriers in Drug Design, "Pergamon Press, 1987 (ed. EB Roche, American Pharmaceutical Association.) Prodrugs according to the invention can be produced, for example, by replacing appropriate functionalities present in the compounds of formula (I) with certain moieties known to those skilled in the art as "pro-residues" as it is described, for example, in "Design of Prodrugs" H Bundgaard (Elsevier, 1985) Some examples of prodrugs according to the invention include: (i) when the compound of formula (I) contains an alcohol functionality (-OH) , an ether thereof, for example, by substitution of hydrogen with (C6) alkanoyloxymethyl; and (ii) when the compound of formula (I) contains a primary or secondary amino functionality (NHR, where R? H), an amide thereof, for example, by substitution of one or both hydrogens with alkanoyl of (CrC 0) ). In the references mentioned above, other examples of substitution groups can be found according to the above examples and examples of other types of prodrugs. The compounds of formula (I) containing one or more asymmetric carbon atoms can exist as two or more stereoisomers. When a compound of formula (I) contains an alkenyl or alkenylene group, geometric isomers cisArans (or Z / E) can be formed and when the compound contains, for example, a keto or oxime group, a tautomeric isomerism ("tautomerism") can occur. ). It should be understood that a single compound can show more than one type of isomerism. All stereoisomers, geometric isomers and tautomeric forms of the compounds of formula (I) are included within the scope of the present invention, including compounds that show more than one type of isomerism and mixtures of one or more thereof.
The cis? Trans isomers can be separated by conventional techniques well known to those skilled in the art, for example, chromatography and fractional crystallization. Conventional techniques for the preparation / isolation of individual enantiomers include the chiral synthesis of an optically pure precursor or the resolution of the racemate (or the racemate of a salt or derivative) using, for example, high pressure chiral liquid chromatography.
(HPLC). Alternatively, the racemate (or a racemic precursor) can be reacted with a suitable optically active compound, for example, an alcohol or, in the case where the compound of formula (I) contains an acidic moiety, a suitable base. The resulting diastereomeric mixture can be separated by chromatography and / or fractional crystallization and convert one or both diastereomers to the corresponding pure enantiomers by means well known to those skilled in the art. The chiral compounds of the invention (and chiral precursors thereof) can be obtained in enantiomerically enriched form using chromatography, typically HPLC, on an asymmetric resin with a mobile phase consisting of a hydrocarbon, typically heptane or hexane, containing 0 to 50% isopropanol, typically 2 to 20% and 0 to 5% of an alkylamine, typically 0.1% diethylamine. The concentration of the eluate produces the enriched mixture.
Stereoisomeric conglomerates can be separated by conventional techniques known to those skilled in the art - see, for example, "Stereochemistry of Organic Compounds" by E L Eliel (Wiley, New York, 1994). The present invention also includes all pharmaceutically acceptable isotope-labeled compounds of formula (I) in which one or more atoms are replaced by atoms having the same atomic number, but different atomic mass or mass number in comparison with the atomic mass or mass number that is normally found in nature. Examples of suitable isotopes for inclusion in the compounds of the invention include hydrogen asotopes such as 2H and 3H, carbon, such as 11C, 13C and 14C, of chlorine, such as 36CI, of fluorine, such as 18F, of iodine, such as 123l and 125l, of nitrogen, such as 13N and 15N, of oxygen, such as 150, 17O and 18O, of phosphorus, such as 32P, and of sulfur, such as 35S. Certain compounds labeled with sotopes of formula (I), for example, those incorporating a radioactive isotope, are useful in studies of drug distribution and / or tissue substrates. The radioactive isotopes tritium, i.e., 3H, and carbon-14, i.e., 14C, are particularly useful for this purpose in view of their ease of incorporation and detection means. Substitution with heavier isotopes such as deuterium, ie, 2H, may produce certain therapeutic advantages as a result of increased metabolic stability, for example, a longer half-life in vivo or lower dosing requirements and therefore may be preferred in some circumstances. Substitution with positron emission isotopes, such as 11C, 18F, 15O, and 13N, may be useful in Positron Emission Topography (PET) studies to examine receptor occupancy in the substrate. The isotope-labeled compounds of formula (I) can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples and Preparations using an isotope-labeled reagent instead of the unlabelled reagent previously employed. . The pharmaceutically acceptable solvates according to the invention include those in which the crystallization solvent can be substituted with isotopes, for example, D2O, d6-acetone and d-DMSO. The compounds of the present invention are antagonists of the NMDA NR2B receptor (N-methyl-D-aspartate) and have several therapeutic applications, particularly in the treatment of pain, stroke, traumatic brain injury, Parkinson's disease, Alzheimer's disease, depression, anxiety, migraine or the like. The compounds of the present invention are useful for the general treatment of pain, particularly neuropathic pain. Physiological pain is an important protective mechanism designed to warn of the danger of potentially damaging stimuli from the external environment. The system works through a specific set of primary sensory neurons and is activated exclusively by noxious stimuli through peripheral transduction mechanisms (Millan 1999 Prog. Neurobio, 57: 1-164, as a reference). These sensory fibers are known as nociceptors and are characterized by small diameter axons with low conduction velocities. The nociceptors encode the intensity, duration and quality of the noxious stimuli and, thanks to their topographically organized projection to the spinal cord, the location of the stimulus. Nociceptors are found in nociceptive nerve fibers of which there are two main types, A-delta fibers (myelinated) and C fibers (unmyelinated). The activity generated by the entrance of the nociceptor is transferred, after a complex processing in the dorsal horn, directly or through nuclei of retransmission of the cerebral stem, to the ventrobasal thalamus and later to the cortex, where the sensation of pain is generated. In acute severe pain and in chronic pain, the same pathways may be involved that are driven by pathophysiological processes and, as such, may fail to provide a protective mechanism and instead contribute to the debilitating symptoms associated with a wide range of disease states. . Pain is a feature of many injuries and disease states. When a substantial injury occurs in a body tissue, due to disease or trauma, the characteristics of nociceptor activation are altered. Sensitization occurs in the periphery, locally around the lesion and centrally where the nociceptors end. This leads to a hypersensitivity at the site of the injury and in nearby normal tissue. In acute pain, these mechanisms can be useful and allow the healing process to take place and the hypersensitivity returns to normal when the lesion has healed. However, in many chronic pain states, hypersensitivity lasts longer than the healing process, which is usually due to an injury to the nervous system. This injury usually leads to maladaptation of the afferent fibers (Woolf & amp;; Salter 2000 Science 288: 1765-1768). Clinical pain is present when discomfort and abnormal sensitivity are among the patient's symptoms. Patients tend to be quite heterogeneous and may present different symptoms of pain. There are several typical subtypes of pain: 1) spontaneous pain that can be dull, burning or throbbing; 2) painful responses to noxious stimuli are exaggerated (hyperalgesia); 3) the pain is produced by normally innocuous stimuli (allodynia) (Meyer et al., 1994 Textbook of Pain 13-44). Although patients with back pain, arthritis pain, CNS trauma or neuropathic pain may have similar symptoms, the underlying mechanisms are different and, therefore, may require different treatment strategies. Therefore, pain can be divided into several distinct areas by its different pathophysiologies, including nociceptive, inflammatory, neuropathic pain, etc. It should be noted that some types of pain have multiple etiologies and, therefore, can be classified in more than one area, for example, back pain. Cancer pain can have nociceptive and neuropathic components. Nociceptive pain is induced by injury to a tissue or by intense stimuli that have the potential to cause injury. Pain afferents are activated by transduction of stimuli by nociceptors to the site of the lesion and sensitize the spinal cord to the level of its termination. Afterwards, it is retransmitted through the spinal tract to the brain where pain is perceived (Meyer et al., 1994 Textbook of Pain 13-44). The activation of the nociceptors activates two different types of afferent nerve fibers. The myelinated A-delta fibers transmit rapidly and are responsible for the sensations of sharp and throbbing pain, while unmyelinated C fibers transmit at lower velocity and drive the dull pain. Acute moderate to severe nociceptive pain is a prominent feature of sprained / sprained pain, postoperative pain (pain after any type of surgical procedure), post-traumatic pain, burns, myocardial infarction, acute pancreatitis and renal colic, but it is not limited to these pains. In addition, acute pain syndromes related to cancer are usually due to therapeutic interactions such as chemotherapy toxicity, immunotherapy, hormone therapy and radiation therapy. Acute nociceptive pain of moderate to severe is a prominent feature, but without limitation, of cancer pain that may be pain related to tumors (eg, bone pain, headache and faciai, visceral pain) or associated with anti-cancer therapy. cancer (for example, post-chemotherapy syndromes, post-surgical chronic pain syndromes, post-radiation syndromes), back pain that may be due to hernias or ruptured invertebral discs or abnormalities in the lumbar facet joints, sacroiliac joints , paraspinal muscles or the posterior longitudinal ligament. Neuropathic pain is defined as pain initiated or caused by a primary lesion or dysfunction in the nervous system (IASP definition). The injury to the nerve can be caused by trauma and disease and, therefore, the term "neuropathic pain" encompasses many disorders with different etiologies. These include, but are not limited to, diabetic neuropathy, post-herpetic neuralgia, back pain, cancer neuropathy, HIV neuropathy, phantom limb pain, Carpus Tunnel Syndrome, chronic alcoholism, hypothyroidism, trigeminal neuralgia, uremia or deficiencies. of vitamins. Neuropathic pain is pathological because it does not have a protective role. It is usually present after the original cause has dissipated, usually lasting for years, and significantly reducing the quality of life of patients (Woolf and Mannion 1999 Lancet 353: 1959-1964). The symptoms of neuropathic pain are difficult to treat, as they are often heterogeneous even among patients with the same disease (Woolf & amp;; Decosterd 1999 Pain Supp. 6: S141-S147; Woolf and Mannion 1999 Lancet 353: 1959-1964). They include spontaneous pain, which may be continuous, or paroxysmal pain and abnormal evoked pain, such as hyperalgesia (increased sensitivity to a noxious stimulus) and allodynia (sensitivity to a normally harmless stimulus). The inflammatory process is a complex series of biochemical and cellular events activated in response to tissue injury or the presence of foreign substances, resulting in swelling and pain (Levine and Taiwo 1994: Textbook of Pain 45-56). Arthritic pain constitutes the majority of the population of inflammatory pains. Rheumatoid disease is one of the most common chronic inflammatory conditions in developed countries and rheumatoid arthritis is a common cause of disability. The exact etiology of RA is unknown, but current hypotheses suggest that both genetic factors and microbiological factors may be important (Grennan &Jayson 1994 Textbook of Pain 397-407). It has been estimated that nearly 16 million Americans have symptomatic osteoarthritis (OA) or a degenerative joint disease, most of which are over 60 years old and this number is expected to increase to 40 million as the age of the population increases , making this a public health problem of enormous magnitude (Houge &Mersfelder 2002 Ann Pharmacother, 36: 679-686, McCarthy et al., 1994 Textbook of Pain 387-395). Most patients with OA seek medical attention due to pain. Arthritis has a significant impact on psychosocial and physical function and is known to be the leading cause of disability in advanced stages of life. Other types of inflammatory pain include, but are not limited to, inflammatory bowel diseases (IBD).
Other types of pain include, but are not limited to: musculoskeletal disorders including, but not limited to, myalgia, fibromyalgia, spondylitis, sero-negative (non-rheumatoid) arthropathies, non-articular rheumatism, dystrophinopathy, glycogenolysis, polymyositis, pyomyositis. - Central pain or "thalamic pain", defined as pain caused by injury or dysfunction of the nervous system including, but not limited to, central pain that appears after a stroke, multiple sclerosis, spinal cord injury, Parkinson's disease and epilepsy. - Cardiac and vascular pain including, but not limited to, angina, myocardial infarction, mitral stenosis, pericarditis, Raynaud's phenomenon, scleroderma, skeletal muscle ischemia. - Visceral pain and gastrointestinal disorders. The viscera include the organs of the abdominal cavity. These organs include the sexual organs, spleen and part of the digestive system. The pain associated with the viscera can be divided into visceral digestive pain and non-digestive visceral pain. The gastrointestinal (Gl) disorders usually found include functional bowel disorders (FBD) and inflammatory bowel diseases (IBD). These Gl disorders include a wide range of disease states that are currently only moderately controlled, including - in the case of FBD, gastroesophageal reflux, dyspepsia, irritable bowel syndrome (IBS) and functional abdominal pain syndrome ( FAPS) and - in the case of IBD, Crohn's disease, ileitis and ulcerative colitis, all these conditions regularly producing visceral pain. Other types of visceral pain include pain associated with dysmenorrhea, pelvic pain, cystitis, and pancreatitis. - Headache including, but not limited to, migraine, migraine with aura, migraine without aura, headaches in clusters and tension headache. - Orofacial pain including, but not limited to, dental pain and temporomandibular myofacial pain.

NR2B Binding Assay The activity of the cycloalkylene amide compounds of the present invention as NR2B antagonists is determined by their ability to inhibit the binding of the NR2B subunit to its receptor sites using radioactive ligands. The NR2B antagonist activity of the cycloalkylene amide compounds is evaluated using the conventional assay procedure described, for example, in J. Pharmacol., 331, p. 117-126, 1997. This method essentially involves determining the concentration of the individual compound that is required to reduce the amount of radiolabeled NR2B ligands by 50% at their receptor sites, thereby providing the IC50 values characteristic of each compound tested. More specifically, the test is carried out as indicated below. Membranes were prepared by homogenization of forebrain of male CD rats weighing 170-190 g using a glass-Tefion homogenizer in sucrose 0.32 M at 4 ° C. The crude core sediment was removed by centrifugation at 1000xg for 10 minutes and the supernatant was centrifuged at 17,000xg for 25 minutes. The resulting pellet was resuspended in 5 mM Tris acetate pH 7.4 at 4 ° C for 10 minutes to lyse the cell particles and centrifuged again at 17000xg. The resulting pellet (membrane P2) was washed twice in Tris acetate, resuspended to 5.5 mg protein / ml and stored at -20 ° C until use. All manipulations were performed on ice and the stock solution and equipment were kept on ice at all times. For the saturation test, the saturation of the receptor was determined by incubating [3 H] -1 - [(1S *, 2S *) - 2-hydroxy-2- (4-hydroxyphenyl) -1-methylethyl] -4 phenylpiperidin-4-ol and 50 μg of P2 membrane protein for 60 minutes at room temperature in a final volume of 100 μl of incubation buffer (50 mM Tris HCl, pH 7.4). The total and non-specific binding (in the presence of a 10 μM concentration of 1 - [(1S *, 2S *) - 2-hydroxy-2- (4-hydroxyphenyl) -1-methylethyl] -4-phenylpiperidin-4 -ol unlabeled) were determined in a concentration range of [3 H] -1 - [(1 S *, 2 S *) - 2-hydroxy-2- (4-hydroxyphenyl) -1-methyl-ethyl] -4-phenylpiperidine- 4-ol (0.625 nM to 60 nM).
For the competition assay, the test compounds were incubated in duplicate with [3H] -1 - [(1 S *, 2S *) - 2-hydroxy-2- (4-hydroxyphenyl) -1-methylethyl] - 5 nM 4-phenylpiperidin-4-ol and 50 μg of P2 membrane protein for 60 minutes at room temperature in a final volume of 100 μl of 50 mM Tris HCl buffer (pH 7.4). The non-specific binding was determined by a concentration of 10 μM of 1 - [(1S *, 2S *) - 2-hydroxy-2- (4-hydroxyphenyl) -1-methylethyl] -4-phenylpiperidin-4-ol no marked (25 μl). For all Ki calculations, the KD derived from the saturation obtained in the saturation test was used. All incubations were terminated by rapid vacuum filtration over a Whatman GF / B glass fiber filter paper soaked in polyethyleneimine 0, 2% using a SKATRON cell harvester followed by three washes with ice-cooled filtration buffer (5 mM Tris HCl, pH 7.4). The radioactivity bound to the receptor was quantified by liquid scintillation counting using a Packard LS counter apparatus. The competition trials were carried out counting Wallac filters GF / B in Betaplate scintillation counters (Wallac). The compound prepared in the working example 11 described below was tested with this method and showed a Ki value of 6.2 nM with respect to the binding affinity for the NR2B receptor. In this assay, the compounds of the present invention showed excellent binding activity by the NR2B receptor.
Functional assay of NR2B in human cells HEK293 cells stably expressing the human NR1 b / 2B receptor were used for all functional assays. The cells were cultured in 75-cm2 culture flasks, using Dulbecco's modified Eagle medium (DMEM, high glucose) supplemented with 10% fetal bovine serum, 52 μg / ml Zeocin, 530 μg / ml Geneticin, 100 units / ml penicillin and 100 μg / ml streptomycin. Cells were maintained in a humidified atmosphere with 5% CO2 at 37 ° C and cells with a confluence of 50-60% were collected by 0.05% trypsin containing 0.53 mM EDTA. The day before the experiment, expression of the NR1 b / 2B receptor was induced by 5 μM ponasteron A in DMEM (40 ml) in the presence of 400 μM ketamine to prevent excitotoxicity. The induction was performed for 19-24 hours, using cells with a confluence of 50-60%. The cells were washed with 10 ml of Hepes Krebs-Ringer buffer without Ca2 + (KRH) containing 400 μM ketamine, and fura-2 acetoxymethyl ester was added for 2 hours at room temperature in the presence of 400 μM ketamine in KRH without Ca2 + (10 ml). Subsequently, the cells were collected in 50 ml tubes by means of a pipette and centrifuged at 850 rpm for 2 minutes. The supernatant was removed and the cells were washed with 10 ml of KRH buffer without Ca2 +, followed by another centrifugation. This manipulation was repeated 4 times to remove the ketamine, glutamate and glycine. The cells were re-suspended in KRH buffer without Ca2 + and 50 μl of cell suspension was added to each well of 96-well plates at a density of 100,000 cells / well, followed by the addition of the test compounds dissolved in 50 μl of KRH without Ca2 +. After preincubation for 30 minutes, the agonists (final concentration of 100 μM glutamic acid and 10 μM glycine) dissolved in 25 μL of KRH containing 9 mM Ca2 + (final concentration 1.8 mM) were added. The Fura-2 fluorescence (excitation wavelengths: 340 nm and 380 nm, emission wavelengths 510-520 nm) was monitored with a fluorescence imaging system, FDSS6000. The fluorescence ratio F340 / F380? (ie, the fluorescence ratio immediately after the agonist - the basal fluorescence ratio, calculated as AUC) was used for the evaluation of the effects of the drug on the changes induced by the agonists in the intracellular Ca2 +. The basal fluorescence ratio was determined in the presence of 10 μM MK-801.
Haloperidol-induced catalepsy test in rats Male CD rats were used on an empty stomach (7-8 weeks). Substantial test compound or vehicle was administered subcutaneously and then haloperidol 0.5 mg / kg s.c. Sixty minutes after the injection of haloperidol, the duration of catalepsy was quantified by placing the front legs of the animals on a raised bar and determining the withdrawal latency of the two front legs of the bar. The limit latency was 60 seconds. The experimenter did not know the treatments during the trial.
Dofetilide binding in humans Human HEK293 cells transfected with HERG were prepared and cultured. The collected cells were suspended in 50 mM Tris-HCl (pH 7.4 at 4 ° C) and homogenized using a portable Polytron PT 1200 disruptor at full power for 20 seconds on ice. The homogenates were centrifuged at 48,000 x g at 4 ° C for 20 minutes. Then, the pellets were resuspended, homogenized and centrifuged once more in the same manner. The final pellets were resuspended in an appropriate volume of 50 mM Tris-HCl, 10 mM KCl, 1 mM MgCl 2 (pH 7.4 at 4 ° C) were homogenized, aliquots were distributed and stored at -80 ° C until use. An aliquot of membrane fractions was used for determination of protein concentration using the BCA protein assay kit (PIERCE) and an ARVOsx plate reader (Wallac). The binding assays were performed in a total volume of 200 μl in 96-well plates. Twenty μl of test compounds were incubated with 20 μl of [3 H] -dofetilide (Amersham, final concentration 0.5 nM) and 160 μl of membrane homogenate (25 μg protein) for 60 minutes at room temperature. The non-specific binding was determined with 10 μM dofetilide at the final concentration. Incubation was stopped by rapid filtration in vacuo on a 0.5% pre-wetted Betaplate GF / B filter using an apparatus to collect Skatron cells with 50 mM Tris-HCl, 10 mM KCl, 10 mM MgCl 2, pH 7.4 at 4 ° C. The filters were dried, placed in sample bags and filled with Betaplate Scint. The radioactivity bound to the filter was quantified by counting in a Wallac Betaplate counter.
Assay HRERG HEK 293 cells stably expressing the potassium HERG channel were used for an electrophysiological study. The methodology for stable transfection of this channel in HEK cells can be found in other references (Z. Zhou et al., 1998, Biophysical journal, 74, pp. 230-241). Before the day of the experiment, the cells were harvested from the culture flasks and cultured on glass coverslips in conventional MEM medium with 10% FCS. The cultured cells were introduced in an incubator at 37 ° C maintained in an atmosphere of 95% O2 / 5% CO2. The cells were studied between 15-28 hours after collection. HERG currents were studied using conventional zone clamping techniques in the whole cell mode. During the experiment, the cells were superfused with an external standard solution of the following composition (mM); NaCl, 130; KCl, 4; CaCl2, 2; MgCl2, 1; Glucose, 10; HEPES, 5; pH 7.4 with NaOH. Whole cell logs were made using a zone clamp amplifier and patch pipettes having a resistance of 1-3 MOhm when filled with the internal standard solution of the following composition (mM); KCl, 130; MgATP, 5; MgCl 2, 1, 0; HEPES, 10; EGTA, 5, pH 7.2 with KOH. Only cells with access resistors below 15 MO and resistance to closure > 1 GO were accepted for further experimentation. The resistance compensation in series was applied up to a maximum of 80%. No escape subtraction was performed. However, the acceptable access resistance depended on the size of the recorded currents and the level of resistance of series resistance that can be used safely. After achieving the entire cell configuration and sufficient for cell dialysis with pipette solution (> 5 min), a conventional voltage protocol was applied to the cell to cause membrane currents. The voltage protocol is as follows. The membrane was depolarized from a holding potential of -80 mV to +20 mV for 1000 ms. This was followed by a voltage drop ramp (speed 0.5 mV msec "1) up to the maintenance potential.The voltage protocol was applied to a cell continuously during the experiment every 4 seconds (0.25 Hz). amplitude of the maximum current induced at approximately -40 mV during the ramp.After the stable evoked current responses in the external solution were obtained, vehicle (0.5% DMSO in standard external solution) was applied for 10-20 minutes by means of a pump Peristaltic Whenever there were minimal changes in the amplitude of the current response evoked in the vehicle control state, the test compound was applied at a concentration of 0.3, 1, 3 or 10 μM for a period of 10 minutes. The 10-minute period included the time during which the supply solution was passing through the tube from the solution tank to the recording chamber by means of the pump. n of cells to the compound solution was more than 5 minutes after the drug concentration in the well of the chamber reached the attempting concentration. There was reversibility. Finally, the cells were exposed to a high dose of dofetilide (5 μM), a specific blocker of IKr, to assess the endogenous insensitive current. All the experiments were carried out at room temperature (23 ± 1 ° C). The evoked membrane currents were recorded in real time in a computer, filtered at 500-1 KHz (Bessel -3dB) and sampled at 1-2 KHz using the zone clamp amplifier and specific software for data analysis. The amplitude of the maximum current, which took place around -40 mV, was measured later in the computer. The arithmetic mean of the ten amplitude values was calculated under control conditions and in the presence of drug. The percentage reduction of IN in each experiment was obtained with the normalized current value using the following formula: IN = (1 - ID / IC) X100, where lD at the mean value of current in the presence of drug e is the value current medium under control conditions. Different experiments were performed for each drug concentration or corresponding time control and the arithmetic mean of each experiment is defined as the result of the study.
Method of PSL in mice A partial ligation surgery of the sciatic nerve (PSL) was performed according to Seltzer et al. (Pain 43, 1990, 205-218). A Von Fray hair test was applied slowly on the surface of the plant of the operated hind paw until the hairs were bent. Each hair was tested ten times in ascending order of strength in different sites of the leg with intervals of one to two seconds between each application. Once the withdrawal response was established, the leg was retested with the same hair. The least amount of force needed to elicit a response was recorded as the threshold for removal of the leg, measured in grams.
In Vitro Micronucleus Assay The in vitro micronucleus assay detects chemically induced micronucleus formation (chromosome disruption and / or loss of the entire chromosome) in vitro, by evaluating treated cultures of Chinese Hamster Ovary cells (CHO-WBL). The growth medium is McCoy's medium 5A supplemented with fetal bovine serum (FBS). The cells are incubated at approximately 37 ° C, with 95% air / 5% CO2 in a humidified chamber. The compound is dissolved in DMSO (dimethyl sulfoxide). The final volume of compound in the medium is 1%. The maximum concentration of compound should be the cytotoxic level or an amount close to this level. With a non-toxic compound, a maximum of 5 mg / ml or the lowest concentration causing precipitation is used. The test conditions include the direct assay and the metabolic activation assay where the compound is tested in the presence of an S9 rat liver fraction induced with Aroclor 1254.
The cultures are started by seeding approximately 1x104 CHO-WBL with exponential growth in McCoy's 5A medium in 8 8-well slide chambers. Twenty-four hours after sowing, the cells are treated with the compounds. In the direct assay, cells are treated with compound and Cytochalasin B for 24 hours. In the metabolic activation assay, the cells are treated with compound in the presence of S9 rat liver fraction for 3 hours, and then the cells are incubated with a new medium including Cytochalasin B for 21 hours. Approximately 24 hours from the start of treatment, the cells are incubated in hypotonic buffer (75 mM KCl) for 5 minutes. After the hypotonic treatment, the cells are fixed in the fixation solution (MeOH: acetic acid = 3: 1 v / v) and fined with acridine orange. One hundred consecutive cells are analyzed by concentration to determine the proportion of these with 1, 2 or > 3 cores per cell and 1000 binucleated cells are analyzed for the presence of micronuclei (at least 500 binucleate cells must be analyzed). A dose-dependent increase two or more times greater than the value of the negative control is considered a positive response.
Serum protein binding Serum protein binding of topical compounds NR2B (1 μM) in humans and ddY mice was measured with an equilibrium dialysis method using a 96-well plate type kit. Soaked Spectra-Por® regenerated cellulose membranes (molecular weight limit 12,000-14,000, 12 mm x 120 mm) were allowed to soak overnight in distilled water, then for 20 minutes in 30% ethanol and finally for 15 minutes in buffer of dialysis (PBS 0.10 M: phosphate buffered saline, pH 7.4). Fresh human and mouse ddY serum (20 ml each) was prepared. Dialysis was prepared with caution of not puncturing or rupturing the membranes and 150 μl of serum was added to one side of each well and 150 μl of dialysis buffer was added to the other side of each well. After 4 hours of incubation at 37 ° C at 60 rpm, the serum and the buffer samples were removed and an aliquot of the collected serum and buffer samples were mixed with the following ratios: 1) 40 μl of serum samples were mixed with 120 μl of buffer 2) 120 μl of buffer samples 40 μl of serum were mixed. Then, the mixed samples were extracted with 600 μl of acetonitrile containing (2R, 3R -2- (d-phenylmethyl) -? / - ( 2-methoxybenzyl) quinuclidin-3-amine at 25 ng / ml (as internal HPLC-MS-MS standard) and was measured with LC / MS / MS analysis Calculations: Unbound substrate fraction, fu = 1 - {([plasma] eq - [buffer] eq) / ([plasma] eq)} where [plasma] eq and [buffer] eq are the substrate concentrations in plasma and buffer, respectively.

Human V1A Binding Assay A paste of CHO cells expressing the human V1a receptor was suspended in a 3-fold volume of wash buffer and cooled with ice (50 mM Tris-HCl, 5 mM MgCl2, protease inhibitors, adjusted pH to 7.4). The cells were homogenized and centrifuged at 25,000 g for 30 minutes at 4 ° C. The pellet was resuspended by homogenization in freezing buffer (50 mM Tris-HCl, 5 mM MgCl 2, 20% glycerol, pH adjusted to 7.4). The membrane homogenate was stored at -80 ° C until use. All handling was done on ice and the mother solution and the equipment were kept on ice at all times.
