DETAILED DESCRIPTION OF THE INVENTION

[0015] Sphingosine-1-phosphate is a pleiotropic signaling factor that mediates diverse biological responses through interactions with members of the endothelial cell differentiation gene family (EDG receptors) of plasma membrane-localized G protein-coupled receptors. Five members of this family, S1P1 (EDG-1), S1P2 (EDG-5), S1P3 (EDG-3), S1P4 (EDG-6), and S1P5 (EDG-8), have been identified across various cell types. Receptor subtypes S1P1, S1P2, and S1P3 are widely expressed in both peripheral tissues and the central nervous system (CNS) and play important roles in cardiovascular regulation, lymphocyte trafficking, and neurogenesis. The S1P4 receptor is primarily expressed in the immune and hematopoietic systems and typically mediates immune cell proliferation and cytokine production in the presence of high concentrations of S1P.

[0016] Selective modulation of S1P1 and S1P5 receptors simultaneously in brain tissue from patients with neurological disorders should provide neuroprotective and remyelination benefits. S1P1 / 5 receptors are expressed on astrocytes, microglia, neurons, and oligodendroglia and have been shown to regulate processes associated with demyelinating neuropathology, including astrocyte activation, microglial activation, oligodendrocyte precursor cell migration and maturation, and oligodendroglial cell survival. Studies in the EAE mouse model of MS have shown that genetic deletion or pharmacological functional antagonism of S1P1 reduces demyelination, axonal loss, and astrogliosis. S1P5 is highly expressed on myelinating oligodendrocytes, and stimulation / modulation of S1P5 has been shown to promote the survival of mature oligodendrocytes. The use of a dual S1P1 / S1P5 agonist or a selective S1P5 agonist in a conditional demyelination Xenopus tadpole model increased myelinated internodes compared to controls—use of a selective S1P1 agonist did not result in the same phenotype. On the other hand, higher S1P1 expression compared to S1P5 in astrocytes, microglia, and endothelial cells is associated with reduced cytokine release and inflammatory signaling and improved BBB integrity. Collectively, these data suggest that modulation of both receptor subtypes simultaneously may result in improved treatment of multiple neurological disorders.

[0017] Fatty acid amide hydrolase (FAAH) is an integral membrane serine hydrolase that can degrade the fatty acid amide family of signaling lipids and hydrolyze selected amide prodrugs. FAAH is highly conserved across species and is expressed to varying degrees in many tissues, including the central nervous system (CNS). Selected carboxylic acids can be converted to more permeable amide prodrugs, which can then cross the blood-brain barrier and be converted to active molecules by the action of FAAH on the prodrug. This results in greater delivery of carboxylic acids to the CNS compared with administration of the parent molecule alone. However, peripherally expressed FAAH simultaneously hydrolyzes the prodrug, resulting in a significant amount of non-productive prodrug conversion. Coadministration of a peripherally restricted FAAH inhibitor with a CNS-permeable FAAH-convertible prodrug increases the selectivity of prodrug delivery to the CNS. It also reduces the exposure of the parent molecule in plasma and peripheral tissues compared to that observed when the prodrug is administered alone.

[0018] Specific Terms Unless otherwise specified, definitions of the following terms used in this application are provided below. The use of the term "including," as well as other forms such as "include," "includes," and "included," is not limiting. The paragraph headings used herein are for organizational purposes only and should not be construed as limiting the subject matter described.

[0019] As used herein, C1-C x is C1-C2, C1-C3...C1-C xBy way of example only, a group designated as "C1-C4" indicates that there are 1 to 4 carbon atoms in the moiety, i.e., the group contains 1 carbon atom, 2 carbon atoms, 3 carbon atoms, or 4 carbon atoms. Thus, by way of example only, "C1-C4 alkyl" indicates that the alkyl group has 1 to 4 carbon atoms, i.e., the alkyl group is selected from among methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, and t-butyl.

[0020] An "alkyl" group refers to an aliphatic hydrocarbon group. An alkyl group is branched or straight-chain. In some embodiments, an "alkyl" group has 1 to 10 carbon atoms (i.e., C1-C 10 (Alkyl). Numerical ranges such as "1 to 10," whenever they appear herein, refer to each integer within the specified range. For example, "1 to 10 carbon atoms" means that the alkyl group consists of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, 4 carbon atoms, 5 carbon atoms, 6 carbon atoms, and so on, up to 10 carbon atoms, although this definition also encompasses occurrences of the term "alkyl" without a specified numerical range. In some embodiments, alkyl is C1-C6 alkyl. In one aspect, alkyl is methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl, or t-butyl. Exemplary alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec-butyl, tertiary butyl, pentyl, neopentyl, or hexyl.

[0021] An "alkylene" group refers to a divalent alkyl radical. Any of the above monovalent alkyl groups may be alkylene by removal of a second hydrogen atom from the alkyl. In some embodiments, alkylene is a C1-C6 alkylene. In other embodiments, alkylene is a C1-C4 alkylene. In certain embodiments, alkylene contains 1 to 4 carbon atoms (e.g., a C1-C4 alkylene). In other embodiments, alkylene contains 1 to 3 carbon atoms (e.g., a C1-C3 alkylene). In other embodiments, alkylene contains 1 to 2 carbon atoms (e.g., a C1-C2 alkylene). In other embodiments, alkylene contains 1 carbon atom (e.g., a C1 alkylene). In other embodiments, alkylene contains 2 carbon atoms (e.g., a C2 alkylene). In other embodiments, alkylene contains 2 to 4 carbon atoms (e.g., a C2-C4 alkylene). Typical alkylene groups include, but are not limited to, -CH2-, -CH(CH3)-, -C(CH3)2-, -CH2CH2-, -CH2CH(CH3)-, -CH2C(CH3)2-, -CH2CH2CH2-, -CH2CH2CH2CH2-, and the like.

[0022] A "deuterated alkyl" refers to an alkyl group where one or more hydrogen atoms of the alkyl are replaced with deuterium.

[0023] The term "alkenyl" refers to a species of alkyl group in which at least one carbon-carbon double bond is present. In one embodiment, an alkenyl group has the formula -C(R)=CR2, where R refers to the remainder of the alkenyl group, which may be the same or different. In some embodiments, R is H or alkyl. In some embodiments, alkenyl is selected from ethenyl (i.e., vinyl), propenyl (i.e., allyl), butenyl, pentenyl, pentadienyl, and the like.

[0091] [ka] or a pharmaceutically acceptable salt or solvate thereof.

[0092] In some embodiments, the compounds described herein are in the form of pharmaceutically acceptable salts.Similarly, the active metabolites of these compounds with the same type of activity are included within the scope of this disclosure.In addition, the compounds described herein can exist not only in unsolvated form, but also in solvated form with pharmaceutically acceptable solvents such as water, ethanol, etc.The solvated form of the compounds presented herein is also considered to be disclosed herein.

[0093] "Pharmaceutically acceptable," as used herein, refers to a material, such as a carrier or diluent, that does not abrogate the biological activity or properties of the compound and is relatively non-toxic, i.e., it may be administered to an individual without causing undesired biological effects or interacting in a deleterious way with any of the components of the composition in which it is contained.

[0094] The term "pharmaceutically acceptable salt" refers to a form of a therapeutically active agent that consists of the cationic form of the therapeutically active agent in combination with a suitable anion, or in an alternative embodiment, the anionic form of the therapeutically active agent in combination with a suitable cation. Handbook of Pharmaceutical Salts: Properties, Selection and Use. International Union of Pure and Applied Chemistry, Wiley-VCH 2002. S.M. Berge, L.D. Bighley, D.C. Monkhouse, J. Pharm. Sci. 1977, 66, 1-19. P.H. Stahl and C.G. Wermuth, editors, Handbook of Pharmaceutical Salts: Properties, Selection and Use, Weinheim / Zurich: Wiley-VCH / VHCA, 2002. Pharmaceutical salts are typically more soluble than non-ionic species, dissolve rapidly in gastric and intestinal fluids, and are therefore useful in solid dosage forms. Furthermore, their solubility is often pH-dependent, allowing for selective dissolution in one part of the gastrointestinal tract or another, an ability that can be manipulated as an aspect of delayed- and sustained-release behavior. Furthermore, salt-forming molecules can be in equilibrium with neutral forms, thereby modulating their passage through biological membranes.

[0116] The administration of compound and composition described herein can be achieved by the method that allows compound to be delivered to the site of action.These methods include but are not limited to enteral route (including oral, gastric or duodenal feeding tube, rectal suppository and rectal enema), parenteral route (including intraarterial, intracardiac, intradermal, intraduodenal, intramedullary, intramuscular, intraosseous, intraperitoneal, intrathecal, intravascular, intravenous, intravitreal, epidural and subcutaneous injection or infusion), inhalation, transdermal, transmucosal, sublingual, buccal and topical (including epidermal, dermal, enema, eye drops, ear drops, intranasal, vaginal) administration, but the most suitable route can depend on the condition or disorder of recipient, for example.

[0117] In some embodiments, pharmaceutical compositions suitable for oral administration are presented as discrete units such as capsules, cachets, or tablets, each containing a predetermined amount of the active ingredient, as a powder or granules, as a solution or suspension in an aqueous liquid or a non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, hi some embodiments, the active ingredient is presented as a bolus, electuary, or paste.

[0118] Pharmaceutical compositions that can be used orally include tablets, push-fit capsules made of gelatin, as well as sealed soft capsules made of gelatin and a plasticizer such as glycerol or sorbitol. Tablets may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared by compressing in a suitable machine the active ingredient in a free-flowing form, such as a powder or granules, optionally mixed with a binder, inert diluent, or lubricant, surfactant, or dispersing agent. Molded tablets can be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. In some embodiments, tablets are coated or scored and formulated to provide a delayed or controlled release of the active ingredient therein. All formulations intended for oral administration should be in dosages suitable for such administration. Push-fit capsules can contain the active ingredient in combination with fillers such as lactose, binders such as starches, and / or lubricants such as talc or magnesium stearate, and optionally stabilizers.

Formulations for injection may be presented in unit dosage form, e.g., in ampoules or multi-dose containers, with added preservatives. The compositions may take the form of suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulating agents such as suspending, stabilizing, and / or dispersing agents. The compositions may be presented in unit-dose or multi-dose containers, e.g., sealed ampoules and vials, and may be stored in powder form or in a freeze-dried (lyophilized) condition requiring only the addition of a sterile liquid carrier, e.g., saline or sterile pyrogen-free water, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules, and tablets of the kind described above.

[0120] Pharmaceutical compositions for parenteral administration include aqueous and non-aqueous (oily) sterile injection solutions of the active compound, which may contain antioxidants, buffers, bacteriostats, and solutes that make the formulation isotonic with the blood of the intended recipient, as well as aqueous and non-aqueous sterile suspensions, which may contain suspending agents and thickening agents. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances that increase the viscosity of the suspension, such as sodium carboxymethylcellulose, sorbitol, or dextran. Optionally, the suspension may further contain suitable stabilizers or agents that increase the solubility of the compound, allowing for the preparation of highly concentrated solutions.

[0121] Pharmaceutical compositions can also be formulated as depot preparations.Such long-acting preparations can be administered by implantation (for example, subcutaneously or intramuscularly) or by intramuscular injection.Therefore, for example, compound can be formulated with suitable polymeric or hydrophobic materials (for example, as emulsion in acceptable oil) or ion exchange resin, or as poorly soluble derivatives, for example, as poorly soluble salts.

[0122] For buccal or sublingual administration, the compositions may take the form of tablets, lozenges, pastilles, or gels formulated in a conventional manner. Such compositions may comprise the active ingredient in a flavored base such as sucrose and acacia or tragacanth.

[0123] The pharmaceutical compositions may also be formulated in rectal compositions such as suppositories or retention enemas, eg, containing conventional suppository bases such as cocoa butter, polyethylene glycol, or other glycerides.

[0124] Pharmaceutical compositions can be administered topically, i.e., non-systemically. This includes applying the compound to the external epidermis or buccal cavity, and instilling the compound into the ear, eye, and nose, so that the compound does not enter the bloodstream in large amounts. In contrast, systemic administration refers to oral, intravenous, intraperitoneal, and intramuscular administration.

[0125] Pharmaceutical compositions suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin to the site of inflammation, such as gels, liniments, lotions, creams, ointments, or pastes, and drops suitable for administration to the eye, ear, or nose. The active ingredient may comprise 0.001% to 10% w / w, for example 1% to 2% by weight, of the formulation for topical administration.

[0126] Pharmaceutical compositions administered by inhalation are conveniently delivered from an insufflator, a nebulizer, a pressurized pack, or other conventional means for delivering an aerosol spray.Pressurized packs can contain a suitable propellant, such as dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide, or other suitable gases.In the case of a pressurized aerosol, the dosage unit can be determined by providing a valve to deliver a metered amount.Alternatively, for administration by inhalation or insufflation, pharmaceutical preparations can be in the form of a dry powder composition, for example, a powder mix of the compound and a suitable powder base, such as lactose or starch.The powder composition can be presented in a unit dosage form, for example, in capsules, cartridges, gelatin, or blister packs, from which the powder can be administered using an inhaler or insufflator.

[0127] In some embodiments, the compounds disclosed herein are formulated to achieve the delivery of the compound to specific regions of the gastrointestinal tract.For example, the compounds disclosed herein are formulated for oral delivery by bioadhesive polymers, pH-sensitive coatings, time-dependent biodegradable polymers, microflora activation systems, etc., to achieve the delivery of the compound to specific regions of the gastrointestinal tract.

[0128] In some embodiments, the compounds disclosed herein are formulated to provide controlled release of the compounds. Controlled release refers to the release of the compounds described herein from a dosage form in which the compounds described herein are incorporated according to a desired profile over a long period of time. Controlled release profiles include, for example, sustained release, extended release, pulsed release, and delayed release profiles. In contrast to immediate release compositions, controlled release compositions allow the delivery of drugs to a subject over a long period of time according to a predetermined profile. Such release rates provide therapeutically effective levels of drugs over a long period of time, thereby providing a longer-lasting pharmacological response while minimizing side effects compared to conventional rapid-release dosage forms. Such long-term response provides many unique advantages that cannot be achieved with corresponding short-acting immediate-release preparations.

[0129] Approaches for delivering intact therapeutic compounds to specific regions of the gastrointestinal tract (e.g., the colon, etc.) include:

[0130] (i) Polymer coating: Intact molecules can be delivered to the colon without being absorbed in the upper part of the intestine by coating the drug molecules with suitable polymers that degrade only in the colon.

[0131] (ii) Coatings with pH-sensitive polymers: The majority of enteric and colon-targeted delivery systems are based on coating tablets or pellets that are filled into conventional hard gelatin capsules. The most commonly used pH-dependent coating polymers are methacrylic acid copolymers, commonly known as Eudragit® S, and more specifically as Eudragit® L and Eudragit® S. Eudragit® L100 and S100 are copolymers of methacrylic acid and methyl methacrylate.

[0132] (iii) coating with biodegradable polymers;

[0133] (iv) embedding into a matrix;

[0134] (v) embedding in biodegradable matrices and hydrogels;

[0135] (vi) embedding in a pH-sensitive matrix;

[0136] (vii) sustained release system;

[0137] (viii) Redox sensitive polymer;

[0138] (ix) bioadhesive systems;

[0139] (x) coating with fine particles;

[0140] (xi) osmotically controlled drug delivery;

[0141] Another approach to colon-targeted drug delivery or controlled release systems involves embedding drugs in polymer matrices to entrap and release the drug in the colon.

[0144] Dosage and treatment regimens In one embodiment, the compounds described herein, or pharmaceutically acceptable salts thereof, are used in the preparation of a medicament for the treatment of a disease or disorder in a mammal that would benefit from the administration of a dual S1P1 and S1P5 receptor agonist. A method for treating any of the diseases or disorders described herein in a mammal in need of such treatment comprises administering to the mammal a therapeutically effective amount of at least one compound described herein, or a pharmaceutically acceptable salt, active metabolite, prodrug, or pharmaceutically acceptable solvate thereof.

[0145] In some embodiments disclosed herein, provided is a method for administering dual S1P1 and S1P5 receptor agonists in combination with additional therapeutic agents.In some embodiments, provided is a method for administering dual S1P1 and S1P5 receptor agonists in combination with peripherally restricted fatty acid amide hydrolase (FAAH) inhibitors.In some embodiments, provided is a method for administering dual S1P1 and S1P5 receptor agonists in combination with peripherally restricted FAAH inhibitors, and the peripherally restricted FAAH inhibitor is ASP-3652.

[0146] In certain embodiments, compositions containing the compounds described herein are administered for preventive and / or therapeutic treatment. In certain therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition in an amount sufficient to cure or at least partially prevent at least one symptom of the disease or condition. The amount effective for this use depends on the severity and course of the disease or condition, previous treatments, the patient's health status, weight, and response to the drug, and the judgment of the treating physician. The therapeutically effective amount is optionally determined by methods including, but not limited to, dose escalation and / or dose-finding clinical trials.

[0147] In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or at risk of a particular disease, disorder, or condition. Such an amount is defined to be a "prophylactically effective amount or dose." For this application, the precise amount will vary depending on the patient's health, weight, and the like. When used in patients, the effective amount for this application will depend on the severity and course of the disease, disorder, or condition, previous treatments, the patient's health status and response to the drugs, and the judgment of the treating physician. In one embodiment, prophylactic treatment involves administering a pharmaceutical composition containing a compound described herein, or a pharmaceutically acceptable salt thereof, to a mammal that has previously experienced at least one symptom of the disease being treated and is now in remission, to prevent the recurrence of the disease or condition symptoms.

[0148] In certain embodiments where the patient's condition does not improve, the compound is administered chronically, i.e., for an extended period of time, including for the patient's lifetime, at the physician's discretion, to ameliorate or otherwise manage or limit the symptoms of the patient's disease or disorder.

[0149] In certain embodiments where a patient's condition is improving, the dose of the administered drug is temporarily reduced or temporarily stopped for a period of time (i.e., a "drug holiday"). In certain embodiments, the length of the drug holiday is between 2 days and 1 year, including, by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during the drug holiday is, by way of example only, 10% to 100%, including, by way of example only, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%.

[0150] Once improvement of the patient's condition occurs, a maintenance dose is administered as needed. Thereafter, in certain embodiments, the dosage or frequency of administration, or both, are reduced, depending on the symptoms, to a level at which the improved disease, disorder, or condition is maintained. In certain embodiments, however, the patient requires intermittent treatment on a long-term basis upon recurrence of symptoms.

[0151] The amount of a given agent that corresponds to such an amount will vary depending on factors such as the particular compound, the disease state and its severity, the identity (e.g., weight, sex) of the subject or host requiring treatment, but will nevertheless be determined by the particular circumstances surrounding the case, including, for example, the particular agent being administered, the route of administration, the disease being treated, and the subject or host being treated.

[0152] In general, however, dosages used for adult human treatment typically range from 0.01 mg to 5000 mg per day. In one aspect, dosages utilized for adult human treatment are from about 1 mg to about 1000 mg per day. In one embodiment, the desired dosage is suitably presented as a single dose or as divided doses administered simultaneously or at appropriate intervals, e.g., as two, three, four or more subdoses per day.

[0153] In one embodiment, a suitable daily dosage for a compound described herein or a pharmaceutically acceptable salt thereof is about 0.01 to about 50 mg per kg of body weight. In some embodiments, the daily dosage or amount of active ingredient in a dosage form will be less than or greater than the ranges set forth herein, depending on many variables related to the individual treatment regimen. In various embodiments, the daily dosage and unit dosage will vary depending on many variables, including, but not limited to, the activity of the compound used, the disease or condition being treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the physician.

[0154] The toxicity and therapeutic efficacy of such treatment regimens include, but are not limited to, LD 50 and ED 50 The dose ratio between toxic and therapeutic effects is the therapeutic index, which is defined as the LD 50 and ED 50 In certain embodiments, data obtained from cell culture assays and animal studies are used in formulating therapeutically effective daily dosage ranges and / or therapeutically effective unit dosages for use in mammals, including humans. In some embodiments, the daily dosage of the compounds described herein is at least 50 mg / kg / day with minimal toxicity and is expressed as a ratio between ED1 and ED2. In certain embodiments, data obtained from cell culture assays and animal studies are used in formulating therapeutically effective daily dosage ranges and / or therapeutically effective unit dosages for use in mammals, including humans. In some embodiments, the daily dosage of the compounds described herein is at least 50 mg / kg / day with minimal toxicity and ED1. 50 In certain embodiments, the daily dosage range and / or unit dosage amount varies within this range depending on the dosage form employed and the route of administration utilized.

[0155] In any of the foregoing aspects, in further embodiments, an effective amount of a compound described herein, or a pharmaceutically acceptable salt thereof, is (a) administered systemically to a mammal, and / or (b) administered orally to a mammal, and / or (c) administered intravenously to a mammal, and / or (d) administered by injection to a mammal, and / or (e) administered topically to a mammal, and / or (f) administered non-systemically or topically to a mammal.

[0156] In any of the foregoing aspects, further embodiments include a single administration of an effective amount of the compound, including further embodiments where (i) the compound is administered once daily, or (ii) the compound is administered multiple times throughout the day to the mammal.

[0157] In any of the foregoing aspects, further embodiments include multiple administrations of an effective amount of the compound, including further embodiments in which (i) the compound is administered continuously or intermittently in a single dose, (ii) the interval between multiple administrations is every 6 hours, (iii) the compound is administered to the mammal every 8 hours, (iv) the compound is administered to the mammal every 12 hours, or (v) the compound is administered to the mammal every 24 hours. In further or alternative embodiments, the method includes a drug holiday, during which administration of the compound is temporarily suspended or the dose of the administered compound is temporarily reduced, and at the end of the drug holiday, administration of the compound is resumed. In one embodiment, the length of the drug holiday varies from 2 days to 1 year.

[0158] In certain instances, it will be appropriate to administer at least one compound described herein, or a pharmaceutically acceptable salt thereof, in combination with one or more other therapeutic agents.

[0159] In one embodiment, the therapeutic effectiveness of one of the compounds described herein is enhanced by the administration of an adjuvant (i.e., the adjuvant has minimal therapeutic benefit on its own, but when combined with another therapeutic agent, enhances the overall therapeutic benefit to the patient). Alternatively, in some embodiments, the benefit experienced by the patient is increased by administering one of the compounds described herein with another agent (which also comprises a therapeutic regimen) that also has a therapeutic effect.

[0160] In one particular embodiment, a compound described herein, or a pharmaceutically acceptable salt thereof, is co-administered with a second therapeutic agent, wherein the compound described herein, or a pharmaceutically acceptable salt thereof, and the second therapeutic agent modulate different aspects of the disease, disorder, or condition being treated, thereby providing a greater overall benefit than either therapeutic agent administered alone.

[0161] In either case, regardless of the disease, disorder, or condition being treated, the overall benefit experienced by the patient will be additive of the two therapeutic agents, or the patient may experience a synergistic benefit.

[0162] In certain embodiments, various therapeutically effective amounts of the compounds disclosed herein are utilized in formulating pharmaceutical compositions and / or in treatment regimens in which the compounds disclosed herein are administered in combination with one or more additional agents, such as additional therapeutically effective drugs, adjuvants, etc. The therapeutically effective amounts of drugs and other agents used in combination therapy regimens are optionally determined by means similar to those specified above for the active ingredients themselves. Additionally, the prevention / treatment methods described herein encompass the use of metronomic dosing, i.e., providing more frequent, lower doses to minimize toxic side effects. In some embodiments, combination therapy regimens encompass treatment regimens in which administration of a compound described herein, or a pharmaceutically acceptable salt thereof, is initiated before, during, or after treatment with a second agent described herein and continued at any time during or after the end of treatment with the second agent. A combination therapy regimen includes treatments in which a compound described herein, or a pharmaceutically acceptable salt thereof, and a second agent used in combination are administered at the same time or at different times and / or at increasing or decreasing intervals during the treatment period. Combination therapy also includes periodic treatments that are started and stopped at various times to aid in the clinical management of the patient.

[0163] It will be understood that dosage regimens to treat, prevent, or ameliorate the condition for which relief is sought will be modified to accommodate a variety of factors (e.g., the disease, disorder, or condition from which the subject suffers, the subject's age, weight, sex, diet, and medical condition). Thus, in some instances, the dosage regimen actually utilized will vary and, in some embodiments, will deviate from the dosage regimens set forth herein.

[0164] With respect to the combination therapies described herein, the dosage of the co-administered compounds will vary depending on the type of co-drug used, the particular drug used, the disease or condition being treated, etc. In additional embodiments, when co-administered with one or more other therapeutic agents, the compounds provided herein are administered simultaneously or sequentially with the one or more other therapeutic agents.

[0165] In combination therapy, the multiple therapeutic agents (one of which is one of the compounds described herein) are administered in any order, or even simultaneously. When administration is simultaneous, the multiple therapeutic agents may, by way of example only, be provided in a single, unified form or in multiple forms (e.g., as a single pill or two separate pills).

[0166] The compounds described herein, or pharmaceutically acceptable salts thereof, as well as combination therapies, may be administered before, during, or after the onset of a disease or condition, and the timing of administering a composition containing the compound may vary. Thus, in one embodiment, the compounds described herein are used as prophylactics to prevent the onset of a disease or condition and are administered continuously to a subject prone to the disease or condition. In another embodiment, the compounds and compositions are administered to a subject during or as soon as possible after the onset of symptoms. In certain embodiments, the compounds described herein are administered as soon as practicable after the onset of a disease or condition is detected or suspected, and for the duration necessary to treat the condition. In some embodiments, the duration of treatment required varies, and the treatment duration is tailored to the specific needs of each subject. For example, in certain embodiments, the compounds described herein, or formulations containing the compounds, are administered for at least two weeks, about one month, to about five years.

The total volume of each incubation was 400 μL, containing a final concentration of 0.5 ng / μL rhFAAH, 1 μM test compound, 1.25% ethanol or 1 μM PF-3845 (FAAH inhibitor), and 0.1% bovine serum albumin in Tris-EDTA buffer (pH 8.0). Incubations were performed at room temperature. At 0, 5, 15, 30, and 60 min, 30 μL aliquots of the reaction mixture were removed and mixed with 300 μL of acetonitrile containing 5 ng / mL terfenadine and 10 ng / mL tolbutamide as internal standards to quench the reaction. The resulting mixture was centrifuged at 4000 rpm at 4°C for 15 min, and 100 μL of the supernatant was subjected to LC-MS / MS analysis to measure the formation of acid metabolites.

[0219] LC-MS / MS analysis A Waters Acquity Ultra Performance LC system was used for sample analysis. Chromatography was performed on a reversed-phase Kinetex 2.6 μm C18 column, 2.1 × 30 mm, 100 Å. Mobile phase A consisted of 0.1% formic acid in water, and mobile phase B consisted of 0.1% formic acid in acetonitrile. The flow rate for acid metabolites of the test compounds was 0.9 mL / min for 1.5 min. The mass spectrometers (API-5500 and API Q Trap 4000, Applied Biosystems / MDS SCIEX Instruments, Framingham, MA, USA) were operated in ESI positive or negative ion MRM mode.

[0220] Data analysis The formation of acid metabolites was monitored and quantified using a single calibration point of 1 μM. The observed rate constants (ke) for acid metabolite formation were calculated by plotting metabolite concentration against time of incubation, with the slope as ke, and are shown in Table 1.
