NOVEL TRPV3 MODULATORS

TECHNICAL FIELD

Compounds that are Transient Receptor Potential Vanilloid 3 (TRPV3) modulators, compositions comprising such compounds, and methods for treating conditions and disorders using such compounds and compositions, are disclosed herein.

BACKGROUND OF THE INVENTION

A subset of the vanilloid channels (TRPV1-4) are referred to as thermoTRPs to reflect the observation that heat elicits channel opening across a continuum of temperatures with thresholds ranging from 25° C. to 52° C. (Caterina, M. J.; Rosen, T. A.; Tominaga, M.; Brake, A. J.; Julius, D., Nature 1999, 398, 436-441). TRPV3 characteristically responds to innocuous heat >31° C., exhibits exquisite sensitivity around the physiological temperature of humans, 37° C., and sensitizes dramatically following repetitive heating (Smith, G. D.; Gunthorpe, M. J.; Kelsell, R. E.; Hayes, P. D.; Reilly, P.; Facer, P.; Wright, J. E.; Jerman, J. C.; Walhin, J. P.; Ooi, L.; Egerton, J.; Charles, K. J.; Smart, D.; Randall, A. D.; Anand, P.; Davis, J. B., Nature 2002, 418, 186-190; Xu, H.; Ramsey, I. S.; Kotecha, S. A.; Moran, M. M.; Chong, J. A.; Lawson, D.; Ge, P.; Lilly, J.; Silos-Santiago, I.; Xie, Y.; DiStefano, P. S.; Curtis, R.; Clapham, D. E., Nature 2002, 418, 181-186; Peier, A. M.; Reeve, A. J.; Andersson, D. A.; Moqrich, A.; Earley, T. J.; Hergarden, A. C.; Story, G. M.; Colley, S.; Hogenesch, J. B.; McIntyre, P.; Bevan, S.; Patapoutian, A., Science 2002, 296, 2046-2049).

TRPV3 is a nonselective cation channel with permeability for calcium, but also to other cations, for example sodium. Multiple compounds that have been shown to activate TRPV3, include: monoterpenes, camphor (Peier, A. M. et al., 2002; Moqrich, A.; Hwang, S. W.; Earley, T. J.; Petrus, M. J.; Murray, A. N.; Spencer, K. S.; Andahazy, M.; Story, G. M.; Patapoutian, A., Science 2005, 307, 1468-1472; Xu, H.; Blair, N. T.; Clapham, D. E., J. Neurosci. 2005, 25, 8924-8937), carvacrol, and thymol (Xu, H.; Delling, M.; Jun, J. C.; Clapham, D. E. Nat. Neurosci. 2006, 9, 628-635; Vogt-Eisele, A. K.; Weber, K.; Sherkheli, M. A.; Vielhaber, G.; Panten, J.; Gisselmann, G.; Hatt, H., Br J. Pharmacol. 2007, 151, 530-540; Story, G. M., Mol Cell Neurosci. 2006, 32, 335-343; Vogt-Eisele, A. K. et al., 2007); cinnamaldehyde (Macpherson, L. J. et al., 2006); incensole acetate (Moussaieff, A.; Rimmerman, N.; Bregman, T.; Straiker, A.; Felder, C. C.; Shoham, S.; Kashman, Y.; Huang, S. M.; Lee, H.; Shohami, E.; Mackie, K.; Caterina, M. J.; Walker, J. M.; Fride, E.; Mechoulam, R., FASEB J. 2008, 22, 3024-3034); and vanilloid analogs, eugenol and ethyl vanillin (Hu, H. Z.; Gu, Q.; Wang, C.; Colton, C. K.; Tang, J.; Kinoshita-Kawada, M.; Lee, L. Y.; Wood, J. D.; Zhu, M. X., J Biol. Chem. 2004, 279, 35741-35748; Vogt-Eisele, A. K. et al., 2007; Xu, H. et al., 2006). Though relatively weak (EC₅₀, ˜40 μM) and nonspecific across TRPs, 2-aminoethoxydiphenylborate (2-APB) and diphenylboronic anhydride (DPBA) have been widely and productively used to characterize key attributes of TRPV3 in cellular assays and electrophysiology (Hu, H. Z. et al., 2004; Chung, M. K.; Lee, H.; Mizuno, A.; Suzuki, M.; Caterina, M. J. J Neurosci. 2004, 24, 5177-5182; Chung, M. K.; Güler, A. D.; Caterina, M. J., J Biol. Chem. 2005, 280, 15928-15941). While heat and direct ligand binding are clearly central to TRPV3 pharmacology, accumulating evidence of potentiation by arachidonic acid, other unsaturated fatty acid derivatives (Hu, H. Z.; Xiao, R.; Wang, C.; Gao, N.; Colton, C. K.; Wood, J. D.; Zhu, M. X., J Cell Physiol. 2006, 208, 201-212), and nitric oxide (Aley, K. O.; McCarter, G.; Levine, J. D., J Neurosci. 1998, 18, 7008-7014; Yoshida, T.; Inoue, R.; Morii, T.; Takahashi, N.; Yamamoto, S.; Hara, Y.; Tominaga, M.; Shimizu, S.; Sato, Y.; Mori, Y., Nat Chem Biol. 2006, 2, 596-607) suggests that authentic activation involves stimulation of G protein-coupled receptors and downstream second messenger signal cascades (e.g., phospholipase C, protein kinase C) that mediate local inflammatory responses and nociceptor sensitization that could enhance TRPV3 function (Xu, H. et al., 2006) in a pathophysiological, as compared to basal state.

Evidence suggests that transcriptional regulation of the TRPV3 gene restricts its basal expression and is responsible for enhanced expression following nerve injury. Levels of TRPV3 mRNA recovered from rat L4 and L5 DRG neurons is elevated in the spinal nerve ligation model of neuropathic pain, as compared to uninjured rats (U.S. Pat. No. 7,396,910). Similar upregulation of TRPV3 has been observed in sensory neurons following peripheral nerve injury in humans (Facer, P.; Casula, M. A.; Smith, G. D.; Benham, C. D.; Chessell, I. P.; Bountra, C.; Sinisi, M.; Birch, R.; Anand, P., BMC Neurol. 2007, 7, 11-22; Smith G. D. et al., 2002).

One feature that distinguishes TRPV3 from the other thermoTRPs is its relatively prominent localization in skin (Peier, A. M. et al., 2002; Xu, H. et al., 2002). TRPV3 is also expressed in dorsal root ganglion, trigeminal ganglion, spinal cord and brain (Xu, H. et al., 2002; Smith G. D. et al., 2002). Its distinctive tissue profile, with significant expression in keratinocytes proximal to nociceptive neurons (Chung, M. K.; Lee, H.; Caterina, M. J., J Biol. Chem. 2003, 278, 32037-32046; Chung, M. K.; Lee, H.; Mizuno, A.; Suzuki, M.; Caterina, M. J. J Biol. Chem. 2004, 279, 21569-21575; Peier, A. M. et al., 2002; Xu, H. et al., 2002) as well as upregulation of TRPV3 in disease states is consistent with a likely role of TRPV3 in pain (Caterina M J., Am J Physiol Regul Integr Comp Physiol. 2007, 292, R64-R76; Lee, H.; Caterina, M. J., Pflugers Arch. 2005, 451, 160-167; Güler, A. D.; Lee, H.; Iida, T.; Shimizu, I.; Tominaga, M.; Caterina, M., J. Neurosci. 2002, 22, 6408-6414; Chung, M. K. et al., 2003; Chung, M. K.; Lee, H.; Mizuno, A.; Suzuki, M.; Caterina, M. J. J Biol Chem. 2004, 279, 21569-21575). In a keratinocyte cell line, stimulation of TRPV3 leads to release of inflammatory mediators including interleukin-1. Thus TRPV3 may also play an important role in regulating inflammation, itch (Steinhoff, M. and Biro, T. J. Invest. Dermatology, 2009, 129, 531-535) and pain that results from the release of inflammatory stimuli. In addition, localization of TRPV3 in non-neuronal tissues, especially skin, suggests also that pharmacological modulation of the channel may provide a therapy to treat diseases that impair the skin barrier (Montell, C. Cell, 2010, April 16, 218-220) and have additional, as yet unidentified, benefit for disease states beyond pain. Accordingly, compounds that can modulate one or more functions of TRPV3 can have various therapeutic utilities.

The present compounds may exist as stereoisomers wherein asymmetric or chiral centers are present. These stereoisomers are “R” or “S” depending on the configuration of substituents around the chiral carbon atom. The terms “R” and “S” used herein are configurations as defined in IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem., 1976, 45: 13-30.

Various stereoisomers of the present compounds and mixtures thereof are included within the scope of this application. Stereoisomers include enantiomers and diastereomers, and mixtures of enantiomers or diastereomers. Individual stereoisomers may be prepared synthetically from commercially available starting materials which contain asymmetric or chiral centers or by preparation of racemic mixtures followed by resolution which is well known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by recrystallization or chromatography and liberation of the optically pure product from the auxiliary or (2) direct separation of the mixture of the mixture of optical enantical enantiomers on chiral chromatographic columns.

Geometric isomers may exist in the present compounds. Various geometric isomers and mixtures thereof resulting from the disposition of substituents around a carbon-carbon double bond, a carbon-nitrogen double bond, a cycloalkyl group, or a heterocycle group are contemplated. Substituents around a carbon-carbon double bond or a carbon-nitrogen bond are designated as being of Z or E configuration and substituents around a cycloalkyl or a heterocycle are designated as being of cis or trans configuration.

Compounds disclosed herein may exhibit the phenomenon of tautomerism.

Thus, the formulae drawings within this specification can represent only one of the possible tautomeric or stereoisomeric forms. It is to be understood that the invention encompasses any tautomeric or stereoisomeric form, and mixtures thereof, and is not to be limited merely to any one tautomeric or stereoisomeric form utilized within the naming of the compounds or formulae drawings.

Compounds of the invention can exist in isotope-labeled or -enriched form containing one or more atoms having an atomic mass or mass number different from the atomic mass or mass number most abundantly found in nature. Isotopes can be radioactive or non-radioactive isotopes. Isotopes of atoms such as hydrogen, carbon, phosphorous, sulfur, fluorine, chlorine, and iodine include, but are not limited to, ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ³²P, ³⁵S, ¹⁸F, ³⁶Cl, and ¹²⁵I. Compounds that contain other isotopes of these and/or other atoms are within the scope of this invention.

In another embodiment, the isotope-labeled compounds contain deuterium (²H), tritium (³H) or ¹⁴C isotopes. Isotope-labeled compounds of this invention can be prepared by the general methods well known to persons having ordinary skill in the art. Such isotope-labeled compounds can be conveniently prepared by carrying out the procedures disclosed in the Examples and Schemes sections by substituting a readily available isotope-labeled reagent for a non-labeled reagent. In some instances, compounds may be treated with isotope-labeled reagents to exchange a normal atom with its isotope, for example, hydrogen for deuterium can be exchanged by the action of a deuteric acid such as D₂SO₄/D₂O. In addition to the above, relevant procedures and intermediates are disclosed, for instance, in Lizondo, J et al., Drugs Fut, 21(11), 1116 (1996); Brickner, S J et al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al., Org Lett, 5(7), 963 (2003); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; U.S. Pat.

The isotope-labeled compounds of the invention may be used as standards to determine the effectiveness of TRPV3 modulators in binding assays. Isotope containing compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the nonisotope-labeled parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al., Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al., J. Labelled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol., 77, 79-88 (1999).

In addition, non-radio active isotope containing drugs, such as deuterated drugs called “heavy drugs,” can be used for the treatment of diseases and conditions related to TRPV3 activity. Increasing the amount of an isotope present in a compound above its natural abundance is called enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %. Replacement of up to about 15% of normal atom with a heavy isotope has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J, Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann. New York Acad. Sci. 1960 84: 736; Czakja D M et al., Am. J. Physiol. 1961 201: 357). Acute replacement of as high as 15%-23% in human fluids with deuterium was found not to cause toxicity (Blagojevic N et al. in “Dosimetry & Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares G and Harling O Eds. 1994. Advanced Medical Publishing, Madison Wis. pp. 125-134; Diabetes Metab. 23: 251 (1997)).

Stable isotope labeling of a drug may alter its physico-chemical properties such as pKa and lipid solubility. These effects and alterations may affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom will be stronger than the same bond between the light isotope and that atom. Accordingly, the incorporation of an isotope at a site of metabolism or enzymatic transformation will slow said reactions potentially altering the pharmcokinetic profile or efficacy relative to the non-isotopic compound.

c. Biological Data

(i) In Vitro Antagonism of Recombinant Human TRPV3 Activation.

Test compounds were evaluated for ability to antagonize the activation of recombinant human TRPV3 using FLIPR® Tetra cellular screening. Specifically, on the day prior to the experiment recombinant HEK293 cells that stably express human TRPV3 were removed from tissue culture flasks and plated in growth medium at 20,000 cells/well into Poly-d-lysine coated black/clear 384-well Plate (Corning, 3845) using a Multidrop® dispenser (ThermoScientific, Waltham, Mass.). Prior to the start of the assay, the medium was removed by aspiration, and cells were loaded with 30 μL no-wash FLIPR® Calcium-4 dye (λ_EX=470-495 nm, λ_EM=515-575 nm; Molecular Devices, Sunnyvale, Calif.). The cells were then incubated for 90-120 minutes in the dark prior to addition of the test compound.

A double-addition protocol was used. The test compound (i.e., the TRPV3 antagonist) was added at the 10 second time point, followed by the addition of a TRPV3 agonist three minutes later. Each test compound evaluated was first dissolved in DMSO to prepare a 10 mM stock solution. A solution (5×) of the test compound was then prepared in DPBS (Dulbecco's Phosphate Buffered Saline) and 10 μL of that solution was added to the cells at a delivery rate of 40 μL/sec. The TRPV3 agonist used to activate human TRPV3 expressed by the HEK3 cells was 2-aminoethoxy-diphenyl borate (2-APB; Tocris Cookson, Ellisville, Mo.) at 80 μM. Final assay volume was 50 μL. Total length of an experimental run was 10 minutes.

Changes in fluorescence were measured over time using the FLIPR® instrument. The intensity of the fluorescence was captured and digitally transferred to an interfaced computer. The maximum response minus minimum response was calculated and expressed as the percentage of the maximum 2-APB response in the absence of antagonist. The concentration of 2-APB corresponds to its EC₈₀.

Table 1 reports the IC₅₀values measured for the test compounds as human TRPV3 antagonists. As used in Table 1, “A” refers to an IC₅₀value of greater than 20 μM, “B” refers to an IC₅₀value in range of 5.1 μM to 20 μM, “C” refers to an IC₅₀value in range of 1.1 μM to 5 μM, “D” refers to an IC₅₀value in range of 501 nM to 1,000 nM, and “E” refers to an IC₅₀value in range of 50 nM to 500 nM. Actual measured values are shown parenthetically after the reported range. In most cases, the values reported are average values from at least two runs (i.e., n≧2).

(ii) In Vitro Metabolic Stability (Human and Rat Microsomal Stability)

Test compounds were evaluated for metabolic stability in an in vitro rat microsomal stability assay using rat (Sprague-Dawley, from BD Biosciences) liver microsomes and/or an in vitro human microsomal stability assay using human (Xenotech) liver microsomes. Incubations were conducted using a 0.5 μM substrate concentration in dimethyl sulfoxide (DMSO) and 0.25 mg/mL microsomal protein in 50 mM phosphate buffer at pH 7.4. Incubations were carried out at 37° C. with a final incubation volume of 135 μL. Time-zero samples were prepared by transferring 13.5 μL of compound-microsomal mixture to the quench plates containing 45 μL of quench solution consisting of 50 nM carbutamide as internal standard in 1:1 methanol:acetonitrile. A 1.5 μL aliquot of reduced nicotine adenine disphosphonucleotide (NADPH) (Chem-Impex Int'L Inc., Lot 12532024) was also added to the time-zero plates. The reaction was initiated by the addition of 13.5 μL NADPH to the compound-microsomal mixture and then quenched after 30 minutes by addition of 15 μL of incubation mixture to 45 μL of quench solution. The percent of parent compound remaining after the 30-minute microsomal incubation was ascertained by HPLC-MS/MS and is reported in the table.

(iii) In Vivo Efficacy Against Neuropathic Pain

Test compounds were evaluated for analgesic effect in an in vivo chronic constriction injury (CCI) model of neuropathic pain. CD1 mice (Charles River) were used for these studies. Prior to testing (2-4 weeks) animals underwent a surgical procedure consisting of approximately 3 loose ligatures around the sciatic nerve. Following sterilization procedures, under isofluorane anesthetic, a 1.5 cm incision was made dorsal to the pelvis. The biceps femoris and gluteous superficialis (right side) were separated and the sciatic nerve exposed, isolated, and 2-4 loose ligatures (5-0 chromic gut) with less than 1 mm spacing were placed around it. Following hemostasis, the wound was sutured (layer of muscle closed with 5-0 nylon suture, and the wound closed with surgical staples) and coated with iodine. The mice were allowed to recover on a warming plate and were returned to their home cages (soft bedding) when able to walk on their own.

Two to four weeks after the surgery, test compound was administered orally (PO) in these mice, and mechanical allodynia was evaluated 1 hour after oral dosing where the threshold to response was assessed using calibrated von Frey monofilaments. The von Frey monofilaments were applied to the hind paw at increasing forces until the animal responded by lifting its paw. Normally, the force of the von Frey monofilament was innocuous and only in the altered state (allodynia or hyperalgesia) did the animals respond to this stimulation. Test compounds were evaluated to determine the degree to which they showed analgesic activity by prolonging the latency to respond to thermal stimulation or increasing the grams of force needed to elicit a withdrawal response. At the end of the experiment, after behavioral testing, plasma (and in some instances brain tissue) was taken for exposure analysis.

Each test compound was evaluated in eight different mice. The data reported in Table 3 represent the average value of the approximate percent effect of each compound in relieving neuropathic pain in mice receiving 100 mg/kg oral dose of the test compound. The grams of force needed to elicit a withdrawal response from the injured mouse that was challenged with vehicle was assigned a 0% effect, while the grams of force needed to elicit a withdrawal response from the control was given a 100% effect.

(iv) Additional In Vivo Pain ModelsThere are a number of additional animal models that can be employed for studying pain. Generally, these pain models mimic one of the mechanisms of pain (e.g., nociceptive, inflammatory, or neuropathic pain), rather than the pain associated with any one disease or injury. Such models provide evidence of whether a drug or therapy will be effective in treating any of a number of injuries, diseases, or conditions that generate pain via a particular mechanism. In addition to the Chronic Constriction Injury Model (CCI) discussed above, other animal models of pain that can be used to evaluate test compounds include, but are not limited to, the Chung model, the carageenan induced hyperalgesia model, and the Freund's complete adjuvant (CFA) induced hyperalgesia model.

(v) In Vivo Efficacy Against ItchTest compounds were evaluated for efficacy against itch in an in vivo mouse model of itch. Specifically, CD1 male mice (about 30 g) were shaved on the back of their neck about 18 hours before testing. Test compound in 10% DMSO/PEG 400 was administered orally. 60 Minutes after oral administration of the test compound, chloroquine (400 g/50 μL) was injected with a Hamilton syringe. Within a minute of injection the mice were observed for 10 minutes and the episodes of scratching were recorded.

d. Methods of Using the Compounds:

Data in Table 1 demonstrates that present compounds are modulators of TRPV3 receptors, and thus are useful in the treatment of diseases, conditions, and/or disorders modulated by TRPV3. The relationship between therapeutic effect and inhibition of TRPV3 has been shown in WO2007/056124; Wissenbach, U. et al., Biology of the cell (2004), 96, 47-54; Nilius, B. et al., Physiol Rev (2007), 87, 165-217; Okuhara, D. Y. et al., Expert Opinion on Therapeutic Targets (2007), 11, 391-401; Hu, H. Z. et al., Journal of Cellular Physiology (2006), 208, 201-212.

One embodiment is therefore directed to a method for treating a disease, condition, and/or disorder modulated by TRPV3 in a subject in need thereof, said method comprises administering to the subject a therapeutically effective amount of a compound, or pharmaceutically acceptable salt, solvate, salt of a solvate or solvate of a salt thereof, optionally with a pharmaceutically acceptable carrier.

Diseases, conditions, and/or disorders that are modulated by TRPV3 include, but are not limited to, migraine, arthralgia, cardiac pain arising from an ischemic myocardium, acute pain, chronic pain, nociceptive pain, neuropathic pain, post-operative pain, pain due to neuralgia (e.g., post-herpetic neuralgia, traumatic neuralgia, fibromyalgia, trigeminal neuralgia), pain due to diabetic neuropathy, dental pain and cancer pain, inflammatory pain conditions (e.g., arthritis and osteoarthritis).

Diseases, conditions, and/or disorders that are modulated by TRPV3 also include, but are not limited to, pain such as neuropathic pain, nociceptive pain, dental pain, HIV pain, cardiac pain arising from an ischemic myocardium, pain due to migraine, arthralgia, neuropathies, neurodegeneration, retinopathy, neurotic skin disorder, stroke, urinary bladder hypersensitiveness, urinary incontinence, vulvodynia, gastrointestinal disorders such as irritable bowel syndrome, gastro-esophageal reflux disease, enteritis, ileitis, stomach-duodenal ulcer, inflammatory bowel disease, Crohn's disease, celiac disease, an inflammatory disease such as pancreatitis, a respiratory disorder such as allergic and non-allergic rhinitis, asthma or chronic obstructive pulmonary disease, irritation of skin, eye or mucous membrane, dermatitis, itch, fervescence, muscle spasms, emesis, dyskinesias, depression, Huntington's disease, memory deficits, restricted brain function, amyotrophic lateral sclerosis (ALS), dementia, arthritis, osteoarthritis, diabetes, obesity, urticaria, actinic keratosis, keratocanthoma, alopecia, Meniere's disease, tinnitus, hyperacusis, anxiety disorders and benign prostate hyperplasia.

One embodiment provides methods for treating pain (for example, migraine, inflammatory pain, acute pain, chronic pain, neuropathic pain, nociceptive pain, arthritic pain, osteoarthritic pain, post-operative pain, cancer pain, lower back pain, diabetic neuropathy, eye pain) in a subject (including human) in need of such treatment.

Certain embodiments provides methods for treating itch in a subject (including human) in need of such treatment.

The methods comprise administering to the subject therapeutically effective amount of a compound as described herein, or a pharmaceutically acceptable salt, solvate, salt of a solvate, or solvate of a salt thereof, optionally with a pharmaceutically acceptable carrier. The method further comprises administration of the present compound as a single dose. The method also comprises repeated or chronic administration of the present compound over a period of days, weeks, months, or longer. In certain embodiments, the method comprises administering to the subject a therapeutically effective amount of a compound as described herein, or a pharmaceutically acceptable salt, solvate, salt of a solvate, or solvate of a salt thereof, in combination with one or more additional agents appropriate for the particular disease, condition, or disorder being treated.

When combinations of a TRPV3 inhibitor and one or more other compounds or agents are administered, the invention contemplates administration via the same route of administration or via differing routes of administration.

Another embodiment provides method for increasing the therapeutic effectiveness or potency of compounds described herein by repeated or chronic administration over a period of days, weeks, or months.

Actual dosage levels of active ingredients in the pharmaceutical compositions can be varied so as to obtain an amount of the active compound(s) that is effective to achieve the desired therapeutic response for a particular patient, compositions and mode of administration. The selected dosage level will depend upon the activity of the particular compound, the route of administration, the duration of treatment, other drugs, compounds and/or materials used in combination with the particular compound employed, the age, sex, weight, condition, general health and prior medical history of the patient being treated, the severity of the condition being treated, and like factors well known in the medical arts.

A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the effective amount of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the compounds employed in the pharmaceutical compositions at levels lower than required to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved. In the treatment of certain medical conditions, repeated or chronic administration of the compounds may be required to achieve the desired therapeutic response. “Repeated or chronic administration” refers to the administration of the compounds daily (i.e., every day) or intermittently (i.e., not every day) over a period of days, weeks, months, or longer. In particular, the treatment of chronic painful conditions is anticipated to require such repeated or chronic administration of compounds described herein. The compounds may become more effective upon repeated or chronic administration such that the therapeutically effective doses on repeated or chronic administration may be lower than the therapeutically effective dose from a single administration.

Compounds can also be administered as a pharmaceutical composition comprising the compounds of interest, or pharmaceutically acceptable salts, solvates, or salts of solvates thereof, in combination with one or more pharmaceutically acceptable carriers. The phrase “therapeutically effective amount” of a compound means a sufficient amount of the compound to treat disorders, at a reasonable benefit/risk ratio applicable to any medical treatment. It will be understood, however, that the total daily usage of the compounds and compositions will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well-known in the medical arts. For example, it is well within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved.

If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions may contain such amounts or submultiples thereof to make up the daily dose. It is understood that the effective daily dose may vary with the duration of the treatment.

The compounds may be administered alone, or in combination with one or more other compounds described herein, or in combination (i.e. co-administered) with one or more additional pharmaceutical agents. For example, one or more compounds, or pharmaceutically acceptable salts, solvates, salts of solvates, or solvates of salts thereof, may be administered in combination with one or more analgesic such as, but not limited to, acetaminophen, salicylates, glucocorticosteroids, opioids such as, but not limited to, morphine; and nonsteroidal anti-inflammatory drugs (NSAIDs), or combinations thereof. In certain embodiments, the analgesic is opioid (e.g., morphine) or nonsteroidal anti-inflammatory drugs (NSAIDs). In one certain embodiments, a compound of the invention is co-administered with nonsteroidal anti-inflammatory drugs (NSAIDs).

Non-limiting examples of NSAIDs include aspirin, diclofenac, diflusinal, etodolac, fenbufen, fenoprofen, flufenisal, flurbiprofen, ibuprofen, indomethacin, ketoprofen, ketorolac, meclofenamic acid, mefenamic acid, meloxicam, nabumetone, naproxen, nimesulide, nitroflurbiprofen, olsalazine, oxaprozin, phenylbutazone, piroxicam, sulfasalazine, sulindac, tolmetin and zomepirac. In certain embodiments, the nonsteroidal anti-inflammatory drug (NSAID) is ibuprofen. Combination therapy includes administration of a single pharmaceutical dosage formulation containing one or more of the compounds and one or more additional pharmaceutical agents, as well as administration of the compounds and each additional pharmaceutical agent, in its own separate pharmaceutical dosage formulation. For example, one or more compounds described herein and one or more additional pharmaceutical agents, may be administered to the patient together, in a single oral dosage composition having a fixed ratio of each active ingredient, such as a tablet or capsule; or each agent may be administered in separate oral dosage formulations.

Where separate dosage formulations are used, the compounds and one or more additional pharmaceutical agents may be administered at essentially the same time (e.g., concurrently) or at separately staggered times (e.g., sequentially).

e. Pharmaceutical Compositions

Further provided herein is a pharmaceutical composition that comprises a compound or a pharmaceutically acceptable salt, solvate, salt of a solvate, or solvate of a salt thereof, formulated together with a pharmaceutically acceptable carrier.

Another aspect provides pharmaceutical composition comprising a compound or a pharmaceutically acceptable salt, solvate, salt of a solvate, or solvate of a salt thereof, in combination with an analgesic (e.g., acetaminophen or opioid such as morphine or other related opioids), or in combination with a nonsteroidal anti-inflammatory drugs (NSAIDs), or a combination thereof, formulated together with a pharmaceutically acceptable carrier.

The pharmaceutical compositions can be administered to humans and other mammals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments or drops), bucally or as an oral or nasal spray. The term “parenterally” as used herein, refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous and intraarticular injection and infusion.

The term “pharmaceutically acceptable carrier” as used herein, means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as, but not limited to, lactose, glucose and sucrose; starches such as, but not limited to, corn starch and potato starch; cellulose and its derivatives such as, but not limited to, sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as, but not limited to, cocoa butter and suppository waxes; oils such as, but not limited to, peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols; such a propylene glycol; esters such as, but not limited to, ethyl oleate and ethyl laurate; agar; buffering agents such as, but not limited to, magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as, but not limited to, sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.

Pharmaceutical compositions for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), vegetable oils (such as olive oil), injectable organic esters (such as ethyl oleate) and suitable mixtures thereof. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants.

These compositions may also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.

Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.

Solid dosage forms for oral administration include capsules, tablets, pills, powders and granules. In such solid dosage forms, the active compound may be mixed with at least one inert, pharmaceutically acceptable excipient or carrier, such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol and silicic acid; b) binders such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose and acacia; c) humectants such as glycerol; d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates and sodium carbonate; e) solution retarding agents such as paraffin; f) absorption accelerators such as quaternary ammonium compounds; g) wetting agents such as cetyl alcohol and glycerol monostearate; h) absorbents such as kaolin and bentonite clay and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such carriers as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.

The solid dosage forms of tablets, dragees, capsules, pills and granules can be prepared with coatings and shells such as enteric coatings and other coatings well-known in the pharmaceutical formulating art. They may optionally contain opacifying agents and may also be of a composition such that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes.

The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned carriers.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan and mixtures thereof.

Besides inert diluents, the oral compositions may also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring and perfuming agents.

Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating carriers or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at room temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.

The present ompounds can also be administered in the form of liposomes. As is known in the art, liposomes are generally derived from phospholipids or other lipid substances. Liposomes are formed by mono- or multi-lamellar hydrated liquid crystals which are dispersed in an aqueous medium. Any non-toxic, physiologically acceptable and metabolizable lipid capable of forming liposomes can be used. The present compositions in liposome form can contain, in addition to a compound of the present invention, stabilizers, preservatives, excipients and the like. The preferred lipids are natural and synthetic phospholipids and phosphatidyl cholines (lecithins) used separately or together.

Methods to form liposomes are known in the art. See, for example, Prescott, Ed., Methods in Cell Biology, Volume XIV, Academic Press, New York, N.Y. (1976), p. 33 et seq.

Dosage forms for topical administration include powders, sprays, ointments and inhalants. The active compound may be mixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives, buffers or propellants which may be required. Opthalmic formulations, eye ointments, powders and solutions are also contemplated as being within the scope of this invention.

The compounds can be used in the form of pharmaceutically acceptable salts derived from inorganic or organic acids. The phrase “pharmaceutically acceptable salt” means those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like and are commensurate with a reasonable benefit/risk ratio.

Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al. describe pharmaceutically acceptable salts in detail in (J. Pharmaceutical Sciences, 1977, 66: 1 et seq). The salts can be prepared in situ during the final isolation and purification of the compounds or separately by reacting a free base function with a suitable organic acid. Representative acid addition salts include, but are not limited to acetate, adipate, alginate, citrate, aspartate, benzoate, benzenesulfonate, bisulfate, butyrate, camphorate, camphorsulfonate, digluconate, glycerophosphate, hemisulfate, heptanoate, hexanoate, fumarate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethansulfonate (isothionate), lactate, malate, maleate, methanesulfonate, nicotinate, 2-naphthalenesulfonate, oxalate, palmitoate, pectinate, persulfate, 3-phenylpropionate, picrate, pivalate, propionate, succinate, tartrate, thiocyanate, phosphate, glutamate, bicarbonate, p-toluenesulfonate and undecanoate. Also, the basic nitrogen-containing groups can be quaternized with such agents as lower alkyl halides such as, but not limited to, methyl, ethyl, propyl, and butyl chlorides, bromides and iodides; dialkyl sulfates like dimethyl, diethyl, dibutyl and diamyl sulfates; long chain halides such as, but not limited to, decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides; arylalkyl halides like benzyl and phenethyl bromides and others. Water or oil-soluble or dispersible products are thereby obtained. Examples of acids which can be employed to form pharmaceutically acceptable acid addition salts include such inorganic acids as hydrochloric acid, hydrobromic acid, sulfuric acid, and phosphoric acid and such organic acids as acetic acid, fumaric acid, maleic acid, 4-methylbenzenesulfonic acid, succinic acid and citric acid.

Basic addition salts can be prepared in situ during the final isolation and purification of the compounds by reacting a carboxylic acid-containing moiety with a suitable base such as, but not limited to, the hydroxide, carbonate or bicarbonate of a pharmaceutically acceptable metal cation or with ammonia or an organic primary, secondary or tertiary amine. Pharmaceutically acceptable salts include, but are not limited to, cations based on alkali metals or alkaline earth metals such as, but not limited to, lithium, sodium, potassium, calcium, magnesium and aluminum salts and the like and nontoxic quaternary ammonia and amine cations including ammonium, tetramethylammonium, tetraethylammonium, methylamine, dimethylamine, trimethylamine, triethylamine, diethylamine, ethylamine and the like. Other representative organic amines useful for the formation of base addition salts include ethylenediamine, ethanolamine, diethanolamine, piperidine, piperazine and the like.

The compounds can exist in unsolvated as well as solvated forms, including hydrated forms, such as hemi-hydrates. In general, the solvated forms, with pharmaceutically acceptable solvents such as water and ethanol among others are equivalent to the unsolvated forms for the purposes of the invention.
