DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] Detailed Description of the Invention The present disclosure relates, at least in part, to modulators or inhibitors of ABHD12. For example, provided herein are compounds capable of inhibiting ABHD12.
[0008] As used herein and in the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, a reference to an "agent" includes a plurality of such agents, and a reference to "the cell" includes a reference to one or more cells (or cells) and equivalents thereof. When ranges for a physical property, such as a molecular weight, or a chemical property, such as a chemical formula, are used herein, all combinations and subcombinations of ranges and specific embodiments therein are intended to be included. The term "about" when referring to a numerical value or numerical range means that the numerical value or numerical range referred to is approximate within experimental variation (or within statistical experimental error), and thus the numerical value or numerical range may vary from 1% to 15% of the stated numerical value or numerical range. The term "comprising" (and related terms such as "comprise" or "comprises", or "having" or "including") is not intended to exclude that in other specific embodiments, embodiments such as, for example, any composition, composition, method or process described herein, may "consist of" or "consist essentially of" the described features.
[0009] definition As used in this specification and the appended claims, unless expressly stated to the contrary, the following terms have the meanings indicated below.
[0010] In certain embodiments, the compounds disclosed herein contain one or more asymmetric centers, thus giving rise to enantiomers, diastereomers and other stereoisomers defined in terms of absolute stereochemistry as (R)- or (S)-. Unless otherwise specified, all stereoisomers of the compounds disclosed herein are intended to be contemplated by the present disclosure. When the compounds described herein contain an alkene double bond, unless otherwise specified, the present disclosure is intended to include both E and Z geometric isomers (e.g., cis or trans). Similarly, all possible isomers and their racemic and optically pure forms and all tautomers are intended to be included. The term "geometric isomer" refers to the E or Z geometric isomers (e.g., cis or trans) of the alkene double bond. The term "positional isomer" refers to structural isomers around a central ring, such as ortho-, meta- and para-isomers around a benzene ring.
[0011] "Tautomer" refers to a molecule capable of proton transfer from one atom of a molecule to another atom of the same molecule. In certain embodiments, the compounds presented herein exist as tautomers. In situations where tautomerization is possible, chemical equilibrium of tautomers may exist. The exact ratio of tautomers depends on several factors, including physical conditions, temperature, solvent, and pH. Some examples of tautomeric equilibrium include the following: [ka]
[0012] "Pharmaceutically acceptable salts" include both acid and base addition salts. A pharmaceutically acceptable salt of any one of the compounds described herein is intended to include any pharmaceutically suitable salt form. Preferred pharmaceutically acceptable salts of the compounds described herein are pharmaceutically acceptable acid addition salts and pharmaceutically acceptable base addition salts.
[0013] "Pharmaceutically acceptable acid addition salts" refer to salts which retain the biological effectiveness and properties of the free bases, which are not biologically or otherwise undesirable, and which are formed with inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, hydroiodic acid, hydrofluoric acid, phosphorous acid, etc. Also included are salts formed with organic acids such as aliphatic mono- and dicarboxylic acids, phenyl-substituted alkanoic acids, hydroxyalkanoic acids, alkanedioic acids, aromatic acids, aliphatic and aromatic sulfonic acids, including, for example, acetic acid, trifluoroacetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, salicylic acid, and the like. Thus, exemplary salts include sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, nitrate, phosphate, monohydrogenphosphate, dihydrogenphosphate, metaphosphate, pyrophosphate, chloride, bromide, iodide, acetate, trifluoroacetate, propionate, caprylate, isobutyrate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, mandelate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, phthalate, benzenesulfonate, toluenesulfonate, phenylacetate, citrate, lactate, malate, tartrate, methanesulfonate, and the like. Salts of amino acids such as arginate, gluconate and galacturonate are also contemplated (see, for example, Berge SM et al., "Pharmaceutical Salts", Journal of Pharmaceutical Science, 66:1-19 (1997)). Acid addition salts of basic compounds are prepared by contacting the free base form with a sufficient amount of the desired acid to produce the salt.
[0014] "Pharmaceutically acceptable base addition salts" refer to salts that retain the biological effectiveness and properties of the free acids, which are not biologically or otherwise undesirable. These salts are prepared by the addition of inorganic or organic bases to the free acids. In certain embodiments, pharma-ceutically acceptable base addition salts are formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Salts derived from inorganic bases include, but are not limited to, sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts, and the like. Salts derived from organic bases include, but are not limited to, salts of primary, secondary and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and base ion exchange resins, such as isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, ethanolamine, diethanolamine, 2-dimethylaminoethanol, 2-diethylaminoethanol, dicyclohexylamine, lysine, arginine, histidine, caffeine, procaine, N,N-dibenzylethylenediamine, chloroprocaine, hydrabamine, choline, betaine, ethylenediamine, ethylenedianiline, N-methylglucamine, glucosamine, methylglucamine, theobromine, purines, piperazine, piperidine, N-ethylpiperidine, polyamine resins, etc. See Berge et al., supra.
[0015] As used herein, "treatment" or "treat" or "alleviate" or "ameliorate" are used interchangeably herein. These terms refer to an approach to obtain beneficial or desired results, including, but not limited to, therapeutic effect and / or prophylactic effect. A "therapeutic effect" refers to the eradication or amelioration of the underlying disease being treated. A therapeutic effect is also achieved by the eradication or amelioration of one or more physiological symptoms associated with an underlying disease, such that an improvement is observed in the patient, even though the patient is still suffering from the underlying disease. For a prophylactic effect, the composition is administered to a patient at risk of developing a particular disease or who reports one or more physiological symptoms of the disease, even if a diagnosis of the disease has not been made.

[0044] In certain embodiments, the compounds described herein are formulated as eye drops for intraocular administration.
[0045] Alternatively, the compositions and compounds disclosed herein are administered by aerosol. This is accomplished by preparing aqueous aerosols, liposomal formulations or solid particles containing the compounds. In some embodiments, non-aqueous (e.g., fluorocarbon propellant) suspensions are used. In some embodiments, ultrasonic nebulizers are used to minimize exposure of the drug to shear that can cause degradation of the compounds contained in the compositions of the present invention. Typically, aqueous aerosols are made by formulating an aqueous solution or suspension of the compositions of the present invention together with conventional pharma- ceutically acceptable carriers and stabilizers. Carriers and stabilizers vary according to the requirements of the particular compositions of the present invention, but typically include non-ionic surfactants (Tweens, Pluronics, or polyethylene glycols), innocuous proteins such as serum albumin, sorbitan esters, amino acids such as oleic acid, lecithin, and glycine, buffers, salts, sugars or sugar alcohols. Aerosols are generally prepared from isotonic solutions.
[0046] Pharmaceutical compositions suitable for parenteral administration comprise, in certain embodiments, a composition of the invention in combination with one or more pharma- ceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions containing antioxidants, buffers, bacteriostats, solutes that render the formulation isotonic with the blood of the intended recipient, or suspending or thickening agents, or sterile powders to be reconstituted into sterile injectable solutions or dispersions immediately prior to use.
[0047] Examples of suitable aqueous and non-aqueous carriers used in pharmaceutical compositions include water, ethanol, polyols (glycerol, propylene glycol, polyethylene glycol, etc.) and suitable mixtures thereof, vegetable oils such as olive oil, and injectable organic acid esters such as ethyl oleate and cyclodextrin. Proper fluidity is maintained, for example, by the use of coating materials such as lecithin, by maintaining the required particle size in the case of dispersions, and by the use of surfactants.
[0048] Enteral pharmaceutical formulations comprising the disclosed compounds, enteric materials and their pharma- ceutically acceptable carriers or excipients are also contemplated. Enteric materials refer to polymers that are substantially insoluble in the acidic environment of the stomach and mostly soluble in intestinal fluids at a particular pH.

[0058] In certain embodiments, the disclosed compound used by one or more of the above methods is one of the specific compounds described herein.
[0059] The disclosed compounds are administered to patients (animals and humans) in need of such treatment in dosages that provide optimal pharmaceutical efficacy. It is understood that the dosage required for any particular use will vary from patient to patient, depending not only on the particular compound or composition selected, but also on the route of administration, the nature of the condition being treated, the age and condition of the patient, any concurrent medications or special diets the patient may follow, and other factors, and the appropriate dosage is ultimately at the discretion of the attending physician. To treat the above conditions and diseases, contemplated compounds disclosed herein are administered orally, subcutaneously, topically, parenterally, by inhalation spray, or rectally in dosage unit formulations containing conventional non-toxic pharmacologic carriers, adjuvants, and vehicles. Parenteral administration includes subcutaneous injections, intravenous or intramuscular injections, or infusion techniques.
[0060] Combination therapy, such as the co-administration of the disclosed compounds and additional active agents as part of a specific treatment plan intended to obtain beneficial effects from the interaction of these therapeutic agents, is also contemplated herein. The beneficial effects of the combination include, but are not limited to, pharmacokinetic or pharmacodynamic interactions resulting from the combination of therapeutic agents. The administration of these combinations of therapeutic agents is typically carried out over a period of time (usually weeks, months or years, depending on the combination selected). Combination therapy is intended to include sequential administration of multiple therapeutic agents (i.e., each therapeutic agent is administered at a different time) as well as near-simultaneous administration of these therapeutic agents or at least two of the therapeutic agents.
[0061] Near-simultaneous administration can be accomplished, for example, by administering to the subject multiple times a single formulation or composition (e.g., a tablet or capsule having a fixed ratio of each therapeutic agent or a single formulation (e.g., capsule) for each of the therapeutic agents). Sequential or near-simultaneous administration of each therapeutic agent can be by any suitable route, including, but not limited to, oral, intravenous, intramuscular, and direct absorption through mucosal tissue. The therapeutic agents can be administered by the same route or by different routes. For example, a first therapeutic agent of a selected combination can be administered by intravenous injection while the other therapeutic agent of the combination is administered orally. Alternatively, for example, all therapeutic agents can be administered orally or all therapeutic agents can be administered by intravenous injection.
[0062] Combination therapy also includes administration of the above-mentioned therapeutic agent further combined with other biologically active ingredients and non-drug therapy.When combination therapy further includes non-drug therapy, the non-drug therapy is administered at any suitable time, as long as the beneficial effect of the interaction of the combination of therapeutic agent and non-drug therapy can be obtained.For example, in appropriate cases, the beneficial effect can still be obtained when the non-drug therapy is temporarily removed from the administration of the therapeutic agent, perhaps for a few days or even weeks.
[0063] The components of the combination are administered to a patient simultaneously or sequentially. It will be understood that the components are present in the same pharma- ceutically acceptable carrier and are therefore administered simultaneously. Alternatively, the active ingredients are present in separate pharmaceutical carriers, such as conventional oral dosage forms, which are administered simultaneously or sequentially.
