WO 2007/100758 PCT/US2007/004912 AMIDE DERIVATIVES AS ION-CHANNEL LIGANDS AND PHARMACEUTICAL COMPOSITIONS AND METHODS OF USING THE SAME [0001] This application claims the benefit of U.S. provisional application nos. 60/776,106, filed February 23, 2006, 60/775,949, filed February 23, 2006, 60/776,058, filed February 23, 2006, 60/776,057, filed February 23, 2006, 60/775,930, filed February 23, 2006, 60/776,033, filed February 23, 2006, 60/775,945, filed February 23, 2006, 60/776,056, filed February 23, 2006, 60/776,105, filed February 23, 2006, 60/776,064, filed February 23, 2006, 60/839,903, filed August 24, 2006, and 60/839,994, filed August 24, 2006, the contents of which are hereby incorporated by reference in their entireties. FIELD OF THE INVENTION [00021 This invention relates to novel compounds and to pharmaceutical compositions containing such compounds. This invention also relates to methods for preventing and/or treating pain and inflammation-related conditions in mammals, such as (but not limited to) arthritis, Parkinson's disease, Alzheimer's disease, stroke, uveitis, asthma, myocardial infarction, the treatment and prophylaxis of pain syndromes (acute and chronic -or neuropathic), traumatic brain injury, acute spinal cord injury, neurodegenerative disorders, alopecia (hair loss), inflammatory bowel disease, urinary incontinence, chronic obstructive pulmonary disease, irritable bowel disease, osteoarthritis, and autoimmune disorders, using the compounds and pharmaceutical compositions of the invention. BACKGROUND OF TIHE INVENTION [0003] Studies of signaling pathways in the body have revealed the existence of ion channels and sought to explain their role. Ion channels are integral membrane proteins with two distinctive characteristics: they are gated (open and closed) by specific signals such as membrane voltage or the direct binding of chemical ligands and, once open, they conduct ions across the cell membrane at very high rates. [0004] There are many types of ion channels. Based on their selectivity to ions, they can be divided into calcium channel, potassium channel, sodium channel, etc. The calcium channel is more permeable to calcium ions than other types of ions, the potassium channel selects potassium ions over other ions, and so forth. Ion channels may also be classified according to their gating mechanisms. In a voltage-gated ion channel, the opening probability depends on the membrane voltage, whereas in.a ligand-gated ion channel, the 1 WO 2007/100758 PCT/US2007/004912 opening probability is regulated by the binding of small molecules (the ligands). Since ligand-gated ion channels receive signals from the ligand, they may also be considered as "receptors" for ligands. [0005] Examples of ligand-gated ion channels include nAChR (nicotinic acetylcholine receptor) channel, GluR (glutamate receptor) channel, ATP-sensitive potassium channel, G-protein activated channel, cyclic-nucleotide-gated channel, etc. [0006] Transient receptor potential (TRP) channel proteins constitute a. large and diverse family of proteins that are expressed in many tissues and cell types. This family of channels mediates responses to nerve growth factors, pheromones, olfaction, tone of blood vessels and metabolic stress et al., and the channels are found in a variety of organisms, tissues and cell types including nonexcitable, smooth muscle and neuronal cells. Furthermore, TRP-related channel proteins are implicated in several diseases, such as several tumors and neurodegenerative disorders and the like. See, for example, Minke, et al., APStracts 9:0006P (2002). [0007] Nociceptors are specialized primary afferent neurons and the first cells in a series of neurons that lead to the sensation of pain. The receptors in these cells can be activated by different noxious chemical or physical stimuli. The essential functions of nociceptors include the transduction of noxious stimuli into depolarizations that trigger action potentials, conduction of action potentials from primary sensory sites to synapses in the central nervous system, and conversion of action potentials into neurotransmitter release at presynaptic terminals, all of which depend'on ion channels. [0008] One TRP channel protein of particular interest is the vanilloid receptor. Also known as VR1, the vanilloid receptor is a non-selective cation channel which is activated or sensitized by a series of different stimuli including capsaicin, heat and acid stimulation and products of lipid bilayer metabolism (anandamide), and lipoxygenase metabolites. See, for example Smith, et al., Nature, 418:186-190 (2002). VR1 does not discriminate among monovalent cations, however, it exhibits a notable preference for divalent cations with a permeability sequence of Ca 2 > Mg 2 + > Na+ = K = Cs
+
. Ca 2 is especially important to VRI function, as extracellular Ca 2 + mediates desensitization, a process which enables a neuron to adapt to specific stimuli by diminishing its overall response to a particular chemical or physical signal. VR1 is highly expressed in primary sensory neurons in rats, mice and humans, and innervates many visceral organs including the dermnnis, bones, bladder, gastrointestinal tract and lungs. It is also expressed in other neuronal and non-neuronal tissues including the CNS, nuclei, kidney, stomach and T-cells. The VR1 channel is a 2 WO 2007/100758 PCT/US2007/004912 member of the superfamily of ion channels with six membrane-spanning domains, with highest homology to the TRP family of ion channels. [00091 VR1 gene knockout mice have been shown to have reduced sensory sensitivity to thermal and acid stimuli. See, for example, Caterina, et al. Science, 14:306-313 (2000). This supports the concept that VR1 contributes not only to generation of pain responses but also to the maintenance of basal activity of sensory nerves. VR1 agonists and antagonists have use as analgesics for the treatment of pain of various genesis or etiology, for example acute, inflammatory and neuropathic pain, dental pain and headache (such as migraine, cluster headache and tension headache). They are also useful as anti-inflammatory agents for the treatment of arthritis, Parkinson's Disease, Alzheimer's Disease, stroke, uveitis, asthma, myocardial infarction, the treatment and prophylaxis of pain syndromes (acute and chronic [neuropathic]), traumatic brain injury, spinal cord injury, neurodegenerative disorders, alopecia (hair loss), inflammatory bowel disease, irritable bowel disease and autoimmune disorders, renal disorders, obesity, eating disorders, cancer, schizophrenia, epilepsy, sleeping disorders, cognition, depression, anxiety, blood pressure, lipid disorders, osteoarthritis, and atherosclerosis. [00101 Compounds, such as those of the present invention, which interact with the vanilloid receptor can thus play a role in treating or preventing or ameliorating these conditions. [00111 A wide variety of Vanilloid compounds of different structures are known in the art, for example those disclosed in European Patent Application Numbers EP 0 347 000 and EP 0 401 903, UK Patent Application Number GB 2226313 and International Patent Application, Publication Number WO 92/09285. Particularly notable examples of vanilloid compounds or vanilloid receptor modulators are capsaicin or trans 8-methyl-N-vanillyl-6 nonenamide which is isolated from the pepper plant, capsazepine (Tetrahedron, 53, 1997, 4791) and olvanil or- N-(4-hydroxy-3-methoxybenzyl)oleamide (J. Med. Chem., 36, 1993, 2595). [00121 International Patent Application, Publication Number WO 02/08221 discloses diaryl piperazine a.d related compounds which bind with high selectivity and high affinity to vanilloid receptors, especially Type I Vanilloid receptors, also known as capsaicin or VR1 receptors. The compounds are said to be useful in the treatment of chronic and acute pain conditions, itch and urinary incontinence. 3 WO 2007/100758 PCT/US2007/004912 [0013] International Patent Application, Publication Numbers WO 02/16317, WO 02/16318 and WO 02/16319 suggest that compounds having a high affinity for the vanilloid receptor are useful for treating stomach-duodenal ulcers. [00141 International Patent Application, Publication No. WO 2005/046683, published May 26, 2005, commonly owned, discloses a series of compounds that have demonstrated activity as VR-1 antagonists, and that are suggested as being useful for the treatment of conditions associated with VR-1 activity. [0015] U.S. Patent Numbers US 3,424,760 and US 3,424,761 both describe a series of 3-Ureidopyrrolidines that are said to exhibit analgesic, central nervous system, and pyschopharmacologic activities. These patents specifically disclose the compounds 1-(1 phenyl-3-pyrrolidinyl)-3-phenyl urea and 1-(1-phenyl-3-pyrrolidinyl)-3-(4-methoxyphenyl) urea respectively. International Patent Applications, Publication Numbers WO 01/62737 and WO 00/69849 disclose a series of pyrazole derivatives which are stated to be useful in the treatment of disorders and diseases associated with the NPY receptor subtype Y5, such as obesity. WO 01/62737 specifically discloses the compound 5-amino-N-isoquinolin-5-yl- 1-[3 (trifluoromethyl)phenyl]-1H-pyrazole-3-carboxamide. WO 00/69849 specifically discloses the compounds 5-methyl-N-quinolin-8-yl-1-[3-(trifluoromethyl)phenyl ]-1H-pyrazole-3 carboxamide, 5-methyl-N-quinolin-7-yl- 1-[3-trifluoromethyl)phenyl]- 1H-pyrazole-3 carboxamide, 5-methyl-N-quinolin-3-yl- 1-[3-(trifluoromethyl)phenyl]- 1H-pyrazole-3 carboxamide, N-isoquinolin-5-yl-5-methyl- 1-[3-(trifluoromethyl)phenyl]-1 H-pyrazole-3 carboxamide, 5-methyl-N-quinolin-5-yl-1-[3-(trifluoromethyl)phenyl]- 1H-pyrazole-3 carboxamide, 1-(3-chlorophenyl)-N-isoquinolin-5-yl-5-methyl- 1H-pyrazole-3-carboxamide, N-isoquinolin-5-yl-l1-(3-methoxyphenyl)-5-methyl- 1H-pyrazole-3-carboxamide, 1-(3 fuorophenyl)-N-isoquinolin-5-yl-5-methyl- IH-pyrazole-3-carboxamide, 1-(2-chloro-5 trifluoromethylphenyl)-N-isoquinolin-5-yl-5-methyl- 1N-pyrazole-3-carboxamide, 5-methyl N-(3-methylisoquinolin-5-yl)-1-[3-(trifluoromethyl) phenyl]-1N-pyrazole-3-carboxamide, 5 methyl-N-( 1,2,3 ,4-tetrahydroisoquinolin-5-yl)-l-[3-(trifluoromethyl)phenyl]-lH-pyrazole-3 carboxamide. [0016] German Patent Application Number 2502588 describes a series of piperazine derivatives. This application specifically discloses the compound N-[3-[2-(diethylamino) ethyl] -1,2-dihydro-4-methyl-2-oxo-7-quinolinyl]-4-phenyl- 1 -piperazinecarboxamide. [0017] We have now discovered that certain compounds have surprising potency and selectivity as VR-1 antagonists. The compounds of the present invention are considered to 4 WO 2007/100758 PCT/US2007/004912 be particularly beneficial as VR-1 antagonists as certain compounds exhibit improved aqueous solubility and metabolic stability. SUMMARY OF THE INVENTION [0018] It has now been found that compounds set forth herein, are capable of modifying mammalian ion channels such as the VR1 cation channel. Accordingly, compounds provided herein are potent VR1 antagonists with analgesic activity by systemic administration. The compounds of the present invention may show low toxicity, good absorption, good half-life, good solubility, low protein binding affinity, low drug-drug interaction, low inhibitory activity at HERG channel, low QT prolongation and good metabolic stability. This finding leads to novel compounds having therapeutic value. It also leads to pharmaceutical compositions having the compounds of the present invention as active ingredients and to their use to treat, prevent or ameliorate a range of conditions in mammals such as but not limited to pain of various genesis or etiology, for example acute, chronic, inflammatory and neuropathic pain, dental pain and headache (such as migraine, cluster headache and tension headache).

Such examples include, but are not limited to, choline ester derivatives and the like, N alkylmorpholine esters and the like. [00190] "Solvate" refers to forms of the compound that are associated with a solvent, usually by a solvolysis reaction. Conventional solvents include water, ethanol, acetic acid and the like. The compounds of the invention may be prepared e.g. in crystalline form and may be solvated or hydrated. Suitable solvates include pharmaceutically acceptable solvates, such as hydrates, and further include both stoichiometric solvates and non-stoichiometric solvates. [00191] "Subject" includes humans. The terms "human," "patient" and "subject" are used interchangeably herein. [00192] "Therapeutically effective amount" means the amount of a compound that, when administered to a subject for treating a disease, is sufficient to effect such treatment for the disease. The "therapeutically effective amount" can vary depending on the compound, the disease and its severity, and the age, weight, etc., of the subject to be treated. [00193] "Treating" or "treatment" of any disease or disorder refers, in one embodiment, to ameliorating the disease or disorder (i.e., arresting or reducing the development of the disease or at least one of the clinical symptoms thereof).

[00194] Other derivatives of the compounds of this invention have activity in both their acid and acid derivative forms, but in the acid sensitive form often offers advantages of solubility, tissue compatibility, or delayed release in the mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well know to practitioners of the art, such as, for example, esters prepared by reaction of the parent acid with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a substituted or unsubstituted amine, or acid anhydrides, or mixed anhydrides. Simple aliphatic or aromatic esters, amides and anhydrides derived from 39 WO 2007/100758 PCT/US2007/004912 acidic groups pendant on the compounds of this invention are preferred prodrugs.

12 arylalkyl esters of the compounds of the invention. [00195] It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed "isomers". Isomers that differ in the arrangement of their atoms in space are termed "stereoisomers". [00196] Stereoisomers that are not mirror images of one another are termed "diastereomers" and those that are non-superimposable mirror images of each other are termed "enantiomers". When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a "racemic mixture". [00197] "Tautomers" refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of 7r electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro- forms of phenylnitromethane, that are likewise formed by treatment with acid or base. Representative enol - keto structures and equilibrium are illustrated below: 40 WO 2007/100758 PCT/US2007/004912 H O 0 H H 0 N H HN 0HI N 0 N O N HN N [001981 Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest. [00199] The compounds of this invention may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)- stereoisomers or as mixtures thereof. Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers. and mixtures, racemic or otherwise, thereof. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art.

[00201] In order that the invention described herein may be more fully understood, the following structures representing compounds typical of the invention are set forth. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting this invention in any manner. [00202] Accordingly, additional groups of particular compounds are provided.

All such variants are contemplated herein and are within the scope of the present invention. [00203] In certain aspects, the present invention provides prodrugs and derivatives of the compounds according to the formulae above. Prodrugs are derivatives of the compounds of the invention, which have cleavable groups and become by solvolysis or under physiological conditions the compounds of the invention, which are pharmaceutically active, in vivo. Such examples include, but are not limited to, choline ester derivatives and the like, N-alkylmorpholine esters and the like. [00204] Other derivatives of the compounds of this invention have activity in both their acid and acid derivative forms, but the acid sensitive form often offers advantages of solubility, tissue compatibility, or delayed release in the mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well know to practitioners of the art, such as, for example, esters prepared by reaction of the parent acid with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a substituted or unsubstituted amine, or acid anhydrides, or mixed anhydrides.

ASSAY METHODS Chronic Constriction Injury Model (CCI Model): [00205] Male Sprague-Dawley rats (270-300 g; B.W., Charles River, Tsukuba, Japan) are used. The chronic constriction injury (CCI) operation is performed according to the method described by Bennett and Xie (Bennett, G.J. and Xie, Y.K. Pain, 33:87-107, 1988). Briefly, animals are anesthetized with sodium pentobarbital (64.8 mg/kg, i.p.) and the left common sciatic nerve is exposed at the level of the middle of the thigh by blunt dissection through the biceps femoris. A portion of the sciatic nerve proximal to its trifurcation is freed of adhering tissue and 4 ligatures (4-0 silk) are tied loosely around it with about 1 mm space. A sham operation is performed as same as CCI surgery except for sciatic nerve ligation. Two weeks after surgery, mechanical allodynia is evaluated by application of 42 WO 2007/100758 PCT/US2007/004912 von Frey hairs (VFHs) to the plantar surface of the hind paw. The lowest amount of force of VFH required to elicit a response is recorded as the paw withdrawal threshold (PWT). VFH testing is performed at 0.5, 1 and 2 hr post-dosing. Experimental data are analyzed using Kruskal-Wallis test followed by Dunn's test for multiple comparisons or Mann-Whitney U test for paired comparison. Caco-2 permeability [00206] Caco-2 permeability is measured according to the method described in Shiyin Yee, Pharmaceutical Research, 763 (1997). [00207] Caco-2 cells are grown on filter supports (Falcon HTS multiwell insert system) for 14 days. Culture medium is removed from both the apical and basolateral compartments and the monolayers are preincubated with pre-warmed 0.3 ml apical buffer and 1.0 ml basolateral buffer for 0.75 hour at 370C in a shaker water bath at 50 cycles/min. The apical buffer consists of Hanks Balanced Salt Solution, 25 mM D-glucose monohydrate, 20. mM MES Biological Buffer, 1.25 mM CaC1 2 and 0.5 mM MgCl 2 (pH 6.5). The basolateral buffer consists of Hanks Balanced Salt Solution, 25 mM D-glucose monohydrate, 20 mM HEPES Biological Buffer, 1.25 mM CaCl 2 and 0.5 mM MgCI2 (pH 7.4). At the end of the preincubation, the media is removed and test compound solution (10PM) in buffer is added to the apical compartment. The inserts are moved to wells containing fresh basolateral buffer and incubated for 1 hr. Drug concentration in the buffer is measured by LC/MS analysis. [00208] Flux rate (F, mass/time) is calculated from the slope of the cumulative appearance of substrate on the receiver side and apparent permeability coefficient (Papp) is calculated from the following equation: Papp (cm/sec) = (F * VD) / (SA * MD) where SA is surface area for transport (0.3 cm 2 ), VD is the donor volume (0.3ml), MD is the total amount of drug on the donor side at t = 0. All data represent the mean of 2 inserts. Monolayer integrity is determined by Lucifer Yellow transport. Human dofetilide binding [00209] Cell paste of HEK-293 cells expressing the HERG product can be suspended in 10-fold volume of 50 mM Tris buffer adjusted at pH 7.5 at 25 0 C with 2 M HCI containing. 1 mM MgCl 2 , 10 mM KCI. The cells are homogenized using a Polytron homogenizer (at the maximum power for 20 seconds) and centrifuged at 4 8,000g for 20 minutes at 4 0 C. The 43 WO 2007/100758 PCT/US2007/004912 pellet is resuspended, homogenized and centrifuged once more in the same manner. The resultant supernatant is discarded and the final pellet is resuspended (10-fold volume of 50 mM Tris buffer) and homogenized at the maximum power for 20 seconds. The membrane homogenate is aliquoted and stored at -80 0 C until use. An aliquot is used for protein concentration determination using a Protein Assay Rapid Kit and ARVO SX plate reader (Wallac). All the manipulation, stock solution and equipment are kept on ice at all time. For saturation assays, experiments are conducted in a total volume of 200 pl. Saturation is determined by incubating 20 pl of [3H]-dofetilide and 160 pl of membrane homogenates (20 30 ptg protein per well) for 60 min at room temperature in the absence or presence of 10 pM dofetilide at final concentrations (20 pl) for total or nonspecific binding, respectively. All incubations are terminated by rapid vacuum filtration over polyetherimide (PEI) soaked glass fiber filter papers using Skatron cell harvester followed by two washes with 50 mM Tris buffer (pH 7.5 at 25 0 C). Receptor-bound radioactivity is quantified by liquid scintillation counting using a Packard LS counter. [00210] For the competition assay, compounds are diluted in 96 well polypropylene plates as 4-point dilutions in semi-log format. All dilutions are performed in DMSO first and then transferred into 50 mM Tris buffer (pH 7.5 at 25 0 C) containing 1 mM MgC1 2 , 10 mM KCI so that the final DMSO concentration became equal to 1%. Compounds are dispensed in triplicate in assay plates (4 pl). Total binding and nonspecific binding wells are set up in 6 wells as vehicle and 10 pM dofetilide at final concentration, respectively. The radioligand is prepared at 5.6x final concentration and this solution is added to each well (36 pl). The assay is initiated by addition of YSi poly-L-lysine Scintillation Proximity Assay (SPA) beads (50 pl, 1 mg/well) and membranes (110 p1, 20 pg/well). Incubation is continued for 60 min at room temperature. Plates are incubated for a further 3 hours at room temperature for beads to settle. Receptor-bound radioactivity is quantified by counting Wallac MicroBeta plate counter. HERG assay [00211] HEK 293 cells which stably express the HERG potassium channel are used for electrophysiological study. The methodology for stable transfection of this channel in HEK cells can be found elsewhere (Z.Zhou et al., 1998, Biophysical Journal, 74, pp230-241). Before the day of experimentation, the cells are harvested from culture flasks and plated onto glass coverslips in a standard Minimum Essential Medium (MEM) medium with 10% Fetal Calf Serum (FCS). The plated cells are stored in an incubator at 37 0 C maintained in an atmosphere of 95%O 2 /5%CO 2 . Cells are studied between 15-28hrs after harvest. 44 WO 2007/100758 PCT/US2007/004912 [00212) HERG currents are studied using standard patch clamp techniques in the whole-cell mode. During the experiment the cells are superfused with a standard external solution of the following composition (mM); NaC1, 130; KC1, 4; CaCl 2 , 2; MgCl 2 , 1; Glucose, 10; HEPES, 5; pH 7.4 with NaOH. Whole-cell recordings are made using a patch clamp amplifier and patch pipettes which have a resistance of 1-3MOhm when filled with the standard internal solution of the following composition (mM); KC1, 130; MgATP, 5; MgC1 2 , 1.0; HEPES, 10; EGTA 5, pH 7.2 with KOH. Only those cells with access resistances below 15MQ and seal resistances >1GQ is accepted for further experimentation. Series resistance compensation is applied up to a maximum of 80%. No leak subtraction was done. However, acceptable access resistance depended on the size of the recorded currents and the level of series resistance compensation that can safely be used. Following the achievement of whole cell configuration and sufficient time for cell dialysis with pipette solution (>5min), a standard voltage protocol was applied to the cell to evoke membrane currents. The voltage protocol is as follows. The membrane was depolarized from a holding potential of-80mV to +40mV for 1000ms. This is followed by a descending voltage ramp (rate 0.5mV msec-1) back to the holding potential. The voltage protocol is applied to a cell continuously throughout the experiment every 4 seconds (0.25Hz). The amplitude of the peak current elicited around -40mV during the ramp is measured. Once stable evoked current responses are obtained in the external solution, vehicle (0.5% DMSO in the standard external solution) is applied for 10-20 min by a peristalic pump. Provided there were minimal changes in the amplitude of the evoked current response in the vehicle control condition, the test compound of either 0.3, 1, 3, 10mM is applied for a 10 min period. The 10 min period included the time which supplying solution is passing through the tube from solution reservoir to the recording chamber via the pump. Exposure time of cells to the compound solution is more than 5min after the drug concentration in the chamber well reaches the intended concentration. There is a subsequent wash period of a 10-20min to assess reversibility. Finally, the cells are exposed to high dose of dofetilide (5mM), a specific IKr blocker, to evaluate the insensitive endogenous current. [00213] All experiments are performed at room temperature (23 : 1 C). Evoked membrane currents are recorded on-line on a computer, filtered at 500-1KHz (Bessel -3dB) and sampled at 1-2KHz using the patch clamp amplifier and a specific data analyzing software. Peak current amplitude, which generally occurs at around -40mV, is measured off line on the computer. 45 WO 2007/100758 PCT/US2007/004912 [00214] The arithmetic mean of the ten values of amplitude is calculated under vehicle control conditions and in the presence of drug. Percent decrease of IN in each experiment is obtained by the normalized current value using the following formula: IN = (1- ID/IC )x 100, where ID is the mean current value in the presence of drug and IC is the mean current value under control conditions. Separate experiments are performed for each drug concentration or time-matched control, and arithmetic mean in each experiment is defined as the result of the study. Mono-lodoacetate (MIA)-induced OA model [00215] Male 6-weeks-old Sprague-Dawley (SD, Japan SLC or Charles River Japan) rats are anesthetized with pentobarbital. Injection site (knee) of MIA is shaved and cleaned with 70% ethanol. Twenty-five ml of MIA solution or saline is injected in the right knee joint using a 29G needle. The effect ofjoint damage on the weight distribution through the right (damaged) and left (untreated) knee is assessed using an incapacitance tester (Linton Instrumentation, Norfolk, UK). The force exerted by each hind limb is measured in grams. The weight-bearing (WB) deficit is determined by a difference of weight loaded on each paw. Rats are trained to measure the WB once a week until 20 days post MIA-injection. Analgesic effects of compounds are measured at 21 days after the MIA injection. Before the compound administration, the "pre value" of WB deficit is measured. After the administration of compounds, attenuation of WB deficits is determined as analgesic effects. Complete Freund's adjuvant (CFA) induced thermal and mechanical hyperalgesia in rats Thermal hyperalgesia [00216] Male 6-week-old SD rats are used. Complete Freund's adjuvant (CFA, 300 mg of Mycobacterium Tuberculosis H37RA (Difco, MI) in 100 pL of liquid paraffin (Wako, Osaka, Japan)) is injected into the plantar surface of a hind paw of the rats. Two days after CFA-injection, thermal hyperalgesia is determined by method described previously (Hargreaves et al., 1988) using the plantar test apparatus (Ugo-Basil, Varese, Italy). Rats are adapted to the testing environment for at least 15 minutes prior to any stimulation. Radiant heat is applied to the plantar surface of a hind paw and paw withdrawal latencies (PWL, seconds) are determined. The intensity of radiant heat is adjusted to produce the stable PWL of 10 to 15 seconds. The test compound is administered in a volume of 0.5 mL per 100 g body weight. PWL are measured after 1, 3 or 5 hours after drug administration. 46 WO 2007/100758 PCT/US2007/004912 Mechanical hyperalgesia [00217] Male 4-week-old SD rats are used. CFA (300 mg of Mycobacterium Tuberculosis H37RA (Difco, MI) in 100 ptL of liquid paraffin (Wako, Osaka, Japan)) is injected into the plantar surface of a hind paw of the rats. Two days after CFA-injection, mechanical hyperalgesia is tested by measuring paw withdrawal threshold (PWT, grams) to pressure using the analgesy-Meter (Ugo-Basile, Varese, Italy). The animals are gently restrained, and steadily increasing pressure is applied to the dorsal surface of a hind paw via a plastic tip. The pressure required to elicit paw withdrawal is determined. The test compound is administered in a volume of 0.5 mL per 100 g body weight. PWT are measured after 1, 3 or 5 hours after drug administration. Pharmaceutical Compositions [00218] When employed as pharmaceuticals, the amide compounds of this invention are typically administered in the form of a pharmaceutical composition. Such compositions can be prepared in a manner well known in the pharmaceutical art and comprise at least one active compound. [00219] Generally, the compounds of this invention are administered in a pharmaceutically effective amount. The amount of the compound actually administered will typically be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like. [00220] The pharmaceutical compositions of this invention can be administered by a variety of routes including by way of non limiting example, oral, rectal, transdermal, subcutaneous, intravenous, intramuscular and intranasal. Depending upon the intended route of delivery, the compounds of this invention are preferably formulated as either injectable or oral compositions or as salves, as lotions or as patches all for transdermal administration. [00221] The compositions for oral administration can take the form of bulk liquid solutions or suspensions, or bulk powders. More commonly, however, the compositions are presented in unit dosage forms to facilitate accurate dosing. The term "unit dosage forms" refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Typical unit dosage forms include prefilled, premeasured ampules or syringes of 47 WO 2007/100758 PCT/US2007/004912 the liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In such compositions, the furansulfonic acid compound is usually a minor component (from about 0.1 to about 50% by weight or preferably from about 1 to about 40% by weight) with the remainder being various vehicles or carriers and processing aids helpful for forming the desired dosing form. [00222] Liquid forms suitable for oral administration may include a suitable aqueous or nonaqueous vehicle with buffers, suspending and dispensing agents, colorants, flavors and the like. Solid forms may include, for example, any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring. 100223] Injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline or other injectable carriers known in the art. As before, the active compound in such compositions is typically a minor component, often being from about 0.05 to 10% by weight with the remainder being the injectable carrier and the like. [00224] Transdermal compositions are typically formulated as a topical ointment or cream containing the active ingredient(s),-generally in an amount ranging from about 0.01 to about 20% by weight, preferably from about 0.1 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and more preferably from about 0.5 to about 15% by weight. When formulated as a ointment, the active ingredients will typically be combined with either a paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with, for example an oil-in-water cream base. Such transdermal formulations are well-known in the art and generally include additional ingredients to enhance the dermal penetration of stability of the active ingredients or the formulation. All such known transdermal formulations and ingredients are included within the scope of this invention. [00225] The compounds of this invention can also be administered by a transdermal device. Accordingly, transdermal administration can be accomplished using a patch either of the reservoir or porous membrane type, or of a solid matrix variety. [00226] The above-described components for orally administrable, injectable or topically administrable compositions are merely representative. Other materials as well as processing techniques and the like are set forth in Part 8 of Remington's Pharmaceutical 48 WO 2007/100758 PCT/US2007/004912 Sciences, 17th edition, 1985, Mack Publishing Company, Easton, Pennsylvania, which is incorporated herein by reference. [00227] The compounds of this invention can also be administered in sustained release forms or from sustained release drug delivery systems. A description of representative sustained release materials can be found in Remington's Pharmaceutical Sciences. [00228] The following formulation examples illustrate representative pharmaceutical compositions of this invention. The present invention, however, is not limited to the following pharmaceutical compositions. Formulation 1 - Tablets [00229] A compound of formula I is admixed as a dry powder with a dry gelatin binder in an approximate 1:2 weight ratio.

Formulation 5 - Injection [00233] The compound of formula I is dissolved or suspended in a buffered sterile saline injectable aqueous medium to a concentration of approximately 5 mg/ml. Formulation 6 - Topical [00234] Stearyl alcohol (250 g) and a white petrolatum (250 g) are melted at about 75°C and then a mixture of a compound of formula I (50 g) methylparaben (0.25 g), 49 WO 2007/100758 PCT/US2007/004912 propylparaben (0.15 g), sodium lauryl sulfate (10 g), and propylene, glycol (120 g) dissolved in water (about 370 g) is added and the resulting mixture is stirred until it congeals. Methods Of Treatment [00235] The present compounds are used as therapeutic agents for the treatment of conditions in mammals. Accordingly, the compounds and pharmaceutical compositions of this invention find use as therapeutics for preventing and/or treating neurodegenerative, autoimmune and inflammatory conditions in mammals including humans. [002361 In a method of treatment aspect, this invention provides a method of treating a mammal susceptible to or afflicted with a condition associated with arthritis, uveitis, asthma, myocardial infarction, traumatic brain injury, acute spinal cord injury, alopecia (hair loss), inflammatory bowel disease and autoimmune disorders, which method comprises administering an effective amount of one or more of the pharmaceutical compositions just described. [00237] In yet another method of treatment aspect, this invention provides a method of treating a mammal susceptible to or afflicted with a condition that gives rise to pain responses or that relates to imbalances in the maintenance of basal activity of sensory nerves. Compounds have use as analgesics for the treatment of pain of various geneses or etiology, for example acute, inflammatory pain (such as pain associated with osteoarthritis and rheumatoid arthritis); various neuropathic pain syndromes (such as post-herpetic neuralgia, trigeminal neuralgia, reflex sympathetic dystrophy, diabetic neuropathy, Guillian Barre syndrome, fibromyalgia, phantom limb pain, post-masectomy pain, peripheral neuropathy, HIV neuropathy, and chemotherapy-induced and other iatrogenic neuropathies); visceral pain, (such as that associated with gastroesophageal reflex disease, irritable bowel syndrome, inflammatory bowel disease, pancreatitis, and various gynecological and urological disorders), dental pain and headache (such as migraine, cluster headache and tension headache). [00238] In additional method of treatment aspects, this invention provides methods of treating a mammal susceptible to or afflicted with neurodegenerative diseases and disorders such as, for example Parkinson's disease, Alzheimer's disease and multiple sclerosis; diseases and disorders which are mediated by or result in neuroinflammation such as, for example traumatic brain injury, stroke, and encephalitis; centrally-mediated neuropsychiatric diseases and disorders such as, for example depression mania, bipolar disease, anxiety, schizophrenia, eating disorders, sleep disorders and cognition disorders; epilepsy and seizure disorders; prostate, bladder and bowel dysfunction such as, for 50 WO 2007/100758 PCT/US2007/004912 example urinary incontinence, urinary hesitancy, rectal hypersensitivity, fecal incontinence, benign prostatic hypertrophy and inflammatory bowel disease; respiratory and airway disease and disorders such as, for example, allergic rhinitis, asthma and reactive airway disease and chronic obstructive pulmonary disease; diseases and disorders which are mediated by or result in inflammation such as, for example rheumatoid arthritis and osteoarthritis, myocardial infarction, various autoimmune diseases and disorders, uveitis and atherosclerosis; itch / pruritus such as, for example psoriasis; alopecia (hair loss); obesity; lipid disorders; cancer; blood pressure; spinal cord injury; and renal disorders method comprises administering an effective condition-treating or condition-preventing amount of one or more of the pharmaceutical compositions just described. [00239] Injection dose levels range from about 0.1 mg/kg/hour to at least 10 mg/kg/hour, all for from about 1 to about 120 hours and especially 24 to 96 hours. A preloading bolus of from about 0.1 mg/kg to about 10 mg/kg or more may also be administered to achieve adequate steady state levels. The maximum total dose is not expected to exceed about 2 g/day for a 40 to 80 kg human patient. [00240] For the prevention and/or treatment of long-term conditions, such as neurodegenerative and autoimmune conditions, the regimen for treatment usually stretches over many months or years so oral dosing is preferred for patient convenience and tolerance. With oral dosing, one to five and especially two to four and typically three oral doses per day are representative regimens. Using these dosing patterns, each dose provides from about 0.01 to about 20 mg/kg of the compound or its derivative, with preferred doses each providing from about 0.1 to about 10 mg/kg and especially about 1 to about 5 mg/kg. [00241] Transdermal doses are generally selected to provide similar or lower blood levels than are achieved using injection doses. [00242] When used to prevent the onset of a neurodegenerative, autoimmune or inflammatory condition, the compounds or thier derivatives of this invention will be administered to a patient at risk for developing the condition, typically on the advice and under the supervision of a physician, at the dosage levels described above. Patients at risk for developing a particular condition generally include those that have a family history of the condition, or those who have been identified by genetic testing or screening to be particularly susceptible to developing the condition. [00243] The compounds of this invention can be administered as the sole active agent or they can be administered in combination with other agents, including other active derivatives.

It will be appreciated that where typical or preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures. [002461 Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. The choice of a suitable protecting group for a particular functional group as well as suitable conditions for protection and deprotection are well known in the art. For example, numerous protecting groups, and their introduction and removal, are described in T. W. Greene and P. G. M. Wuts, Protecting Groups in Organic Synthesis, Second Edition, Wiley, New York, 1991, and references cited therein. [00247] The target compounds are synthesized by known reactions outlined in the following schemes. The products are isolated and purified by known standard procedures. Such procedures include (but are not limited to) recrystallization, column chromatography or HPLC.

General Method for Automated parallel LC-MS Purification of Libraries [00459] The libraries were purified using a Perkin Elmer API100 mass spectrometer coupled to Shimadzu LC pumps. The chromatographic method employed was 10-100% gradient of acetonitrile to water over 8 minutes at a flow rate of 6 ml per minute. The column used was a O10X50mm YMC C18 and the compounds were collected using a Gilson 204 fraction collector. [00460] Following the methods described above and the appropriate reagents, starting materials and purification methods known to those skilled in the art, the amide compounds of this invention were or can be prepared. [00461] The synthetic and biological examples presented herein are offered to illustrate this invention and are not to be construed in any way as limiting the scope of this invention. In the examples below, all temperatures are in degrees Celsius (unless otherwise indicated). [00462] The compounds that have been prepared in accordance with the invention are presented in Table 1, below. The syntheses of these representative compounds were carried out in accordance with the methods set forth above, and activity of the compounds was measured by percent inhibition in a calcium uptake assay, the details of which are described below. Calcium Uptake Assay. [00463] Functional activity of compounds against the VR1 receptor was determined by measuring changes in intracellular calcium in HEK 293 cells expressing hVR1. Compounds were examined for their ability to inhibit agonist-induced calcium influx. Dual wavelength ratiometric dye, Fura2, was used as an indicator of relative levels of [Ca 2+] in a 96-well format using a Flex Station®, Molecular Devices. 145 WO 2007/100758 PCT/US2007/004912 Cell line and culture conditions: [00464] hVR1 was cloned into a peDNA5/TO vector from Invitrogen and stably transformed into T-REx HEK 293 cell line from Invitrogen. HEK 293 cells expressing hVR1 were grown to confluency (24 hour culture) on PDL-coated, plastic 96-well black-walled plates, in the presence of DMEM medium containing 5% PenStrep, 5% Glutamax, 200 p.g/mL Hygromycin, 5pg/mL Blasticidin and 10% heat inactivated FBS. Twenty-four hours prior to assay, cells were transferred to DMEM media containing 1 p.g/mL doxycycline. Prior to the assay, cells were loaded with 5 gg/mL Fura-2 (Molecular Probes) in saline solution (130 mM NaC1, 3 mM KC1, 1 mM CaCl 2 , 0.6 mM MgCl 2 , 10 mM HEPES, 10 mM glucose and 50 mM sucrose pH 7.4) at 37 0 C for 40 minutes. The dye was then aspirated and replaced with 100 ItL saline before commencement of the assay in Flex Station . Agonist concentration and compound dilutions: [00465] The agonist EC 50 was determined at the start of the assay and compound ICso 0 experiments were run using an agonist concentration equal to its EC 5 so as stimulus. The agonists used were capsaicin (ECs 5 o0= 2.5 nM) and protons (saline solution plus 10 mM citric acid buffered to pH 5.7 with HCI). Compounds were tested at concentrations ranging from 10 nM to 3.3 [tM. [00466] The assay consists of two stages: a pre-treatment phase followed by a treatment phase. 50il of a compound solution was added to the cells (Pre-treatment). In some instances, following pre-treatment, 50pd of the test compound in a saline solution at pH 5.1 was added (Treatment). Compounds were tested as follows: For the pre-treatment phase, 50 pL of 3x concentration of test compound in saline is added to cells containing 100 [tL of saline to achieve a final concentration ofx. For the treatment phase, at a determined time after pre-treatment, 50 tL of test compound plus agonist solution is added to cells at the relevant concentrations. [00467] Recordings were made at 4 second intervals at wavelengths of 340 nM and 380 nM and the fluorescence ratio analyzed. Responses were measured as peak fluorescence ratio after compound-agonist addition minus baseline fluorescence ratio prior to treatment and were calculated using the SoftMaxPro software from Molecular Devices. Percent inhibition was calculated as follows and is depicted in Table 1: (Compound Response - Control Response) Percentage inhibition = 1 - X 100 (Agonist Response - Control Response) 146 WO 2007/100758 PCT/US2007/004912 TABLE 1: AMIDE COMPOUNDS I '~1 tR.CTUR. obe d ? . of" .JH NMR ,V~~'4 'ni I ,a o 338.29 A83 H (337.42) A 83 339.20 (d 6 -DMSO) 8 10.73 (s, 1H) 9.38 (s, 1H) 45 3 .

The reaction mixture is split into two groups, a non-P450 and a P450 group. NADPH is only added to the reaction mixture of the P450 group. An aliquot of samples of P450 group is collected at 0, 10, 30, and 60 min time point, where 0 min time point indicated the time when NADPH is added into the reaction mixture of P450 group. An aliquot of samples of non-P450 group is collected at -10 and 65 min time point. Collected aliquots are extracted with acetonitrile solution containing an internal standard. The precipitated protein is spun down in centrifuge (2000 rpm, 15 min). The compound concentration in supernatant is measured by LC/MS/MS system. [00471] The half-life value is obtained by plotting the natural logarithm of the peak area ratio of compounds/ internal standard versus time. The slope of the line of best fit through the points yields the rate of metabolism (k).

During acclimation period, all animals receive food and water ad libitum. However, food but not water is removed from the animal's cages at least 12 hours before initiation of the experiment. During the first 3 hours of experimentation, the animals receive only water ad libitum. At least three animal each are tested for intravenous and oral dosage. For intravenous formulation, compounds were dissolved (0.25 to 1 mg/mL) in a mixture of 3% dimethyl sulfoxide, 40% PEG 400 and the rest percentage of 40% Captisol in water (w/v). For oral formulation, compounds of this invention are dissolved (2 mg/mL) in a mixture of 5% of 10% Tween 80 in water (v/v) and 95% of 0.5 % methyl cellulose in water (w/v). The animals are weighed before dosing. The determined body weight is used to calculate the dose volume for each animal. Dose volume (mL/kg) = 1 mg/kg/formulation concentration (mg/mL) [00474] In instances where the formulation concentrations were less than 0.5 mg/mL, the dosing volume is about 2 mL/kg. PO rats are typically dosed through oral gavage at 2.5 mL/kg to achieve a dose level of 5 mg/kg. For IV dosing, blood samples are collected (using a pre-heparinized syringe) via the jugular vein catheter at 2, 5, 15, 30, 60, 120, 180, 300, 480, and 1440 minutes post dosing. For PO dosing, blood samples are collected (using a pre heparinized syringe) via the jugular vein catheter before dosing and at 5, 15, 30, 60, 120, 180, 300, 480, and 1440 minutes post dosing. About 250 uL of blood is obtained at each time point from the animal. Equal volumes of 0.9% normal saline are replaced to prevent dehydration. The whole blood samples are maintained on ice until centrifugation. Blood samples are then centrifuged at 14,000 rpm for 10 minutes at 4 0 C and the upper plasma layer transferred into a clean vial and stored at -80 0 C. The resulting plasma samples are then analyzed by liquid chromatography-tandem mass spectrometry. Following the measurement of plasma samples and dosing solutions, plasma concentration-time curve is plotted. Plasma exposure is calculated as the area under the concentration-time curve extrapolated to time infinite (AUCinf). The AUCinf is averaged and the oral bioavailability (%F) for individual animal is calculated as: [00475] AUCinf (PO)/AUCinf (IV), normalized to their respective dose levels. The %F is reported as the mean %F of all animals dosed orally with the compound of the invention at the specified level (Table 6).

Such 96-well system was described in Journal ofMedicinal Chemistry, 1998, vol.41, No.7, 1007 1010. 4% phosphatidylcholine and 1% stearic acid in dodecane were used as artificial membrane material. The acceptor plate (96 well hydrophobic filter plate (MAIP N45, Millipore)) was prepared by adding 5 uiL of artificial membrane material on the top of the filter and the plate was filled with 250 ptL of 2-(N-morpholino)ethanesulfonic acid (MES) buffered Hank's balanced salt solution (HBSS) (pH 6.5). The donor plate (Transport Receiver plate (MATRNPS50, Millipore)) was filled with 300 JtL of MES buffered HBSS (pH 6.5) containing 10 1 ±M of the test compounds. The acceptor plate was placed onto the donor plate to form a "sandwich" and was incubated at 30'C for 2.5 hours. After the incubation period, acceptor, donor and initial donor solution (reference) were analyzed via 166 WO 2007/100758 PCT/US2007/004912 LC-MS/MS. Data were reported as the effective permeability value in cm X 10" 6 /see and the membrane retention value. Intrinsic Clearance [00479] Test compounds (1 [M) were incubated with 1 mM MgCl 2 , 1 mM NADP+, 5 mM isocitric acid, 1U/mL isocitric dehydrogenase and 0.8 mg/mL HLM(human liver microsomes) in 100 mM potassium phosphate buffer (pH 7.4) at 37 0 C on a number of 384-well plates. At several time points, a plate was removed from the incubator and the reaction was terminated with two incubation volumes of acetonitrile. The compound concentration in supernatant was measured by LC/MS/MS system. The intrinsic clearance value (Clint) was calculated using following equations: Clint (pl/min/mg protein) = (k x incubation volume) / Protein concentration k (min

l) = - slope of In(concentration vs. time) Example 1 Calcium imaging assay [00480] VR1 protein is a heat-gated cation channel that exchanges approximately ten calcium ions for every sodium ion resulting in neuronal membrane depolarization and elevated intracellular calcium levels. Therefore the functional activity of compounds at the VR1 receptor may be determined by measuring changes in intracellular calcium levels in neurons such as the dorsal root ganglion. [00481] DRG neurons were grown on PDL coated 96-well black-walled plates, in the presence of DMEM medium containing 5% Penstrep, 5% Glutamax, 200 pg/ml hygromycin, 5 p.g/ml blasticide and 10% heat inactivated FBS. Prior to assay, cells were loaded with 5 gg/ml Fura2 in normal saline solution at 37 0 C for 40 minutes. Cells were then washed with normal saline to remove dye before commencement of the experiment. [004821 The plated neurons were transferred into a chamber on the stage of a Nikon eclipse TE300 microscope after which neurons were allowed to attain a stable fluorescence for about 10 minutes before beginning the experiment. The assay consists of two stages, a pretreatment phase followed by a treatment phase. First, a solution of the test compound was added from a multivalve perfusion system to the cells for 1 minute (pretreatment). 167 WO 2007/100758 PCT/US2007/004912 Immediately following, capsaicin (250 nM) was added in the presence of the test compound (treatment) for a specific period between 20 and 60 seconds. [00483] Fura2 was excited at 340 and 380 nM to indicate relative calcium ion concentration. Changes in wavelength measurements were made throughout the course of the experiment. The fluorescence ratio was calculated by dividing fluorescence measured at 340 nM by that at 380 nM. Data were collected using Intelligent Imaging's Slidebook software. All compounds that inhibited capsaicin induced calcium influx greater than 75% were considered positives. [00484] Table 8 provides the data obtained. Figure 1 demonstrates results obtained when compound 225 is administered with capsaicin. Fluorescence reflecting calcium ion influx is reduced.

Such data is also graphically depicted in Figures 2-6, where significant reduction of the capsaicin response is observed in the presence of the representative test compound. No such reduction in response is observed in the absence of the test compound. Example 3 Whole-cell patch clamp electrophysiology [00487] Dorsal root ganglion (DRG) neurons were recovered from either neonatal or adult rats and plated onto poly-D-lysine coated glass coverslips. The plated neurons were transferred into a chamber to allow drug solutions to be added to the cells using a computer controlled solenoid-valve based perfusion system. The cells were imaged using standard DIC optics. Cells were patched using finely-pulled glass electrodes. Voltage-clamp 168 WO 2007/100758 PCT/US2007/004912 electrophysiology experiments were carried out using an Axon Instruments Multiclamp amplified controlled by pCLAMP8 software. [00488] The cells were placed into a whole-cell voltage clamp and held at a voltage of -80mV while monitoring the membrane curient in gap-free recording mode. 500nM capsaicin was added for 30 seconds as a control. Test compounds at various concentrations were added to the cells for 1 minute prior to a 30 second capsaicin application. Differences between control experiments and drug positive capsaicin experiments were used to determine the efficacy of each test compound. All compounds that inhibited capsaicin induced current greater than 50% were considered positives. The data obtained for compound 240 is set forth in Table 9.
