BACKGROUND

Skeletal muscle is a mechanically and energetically active organ, supporting vital processes such as respiration and locomotion, and is a major site of glucose and lipid metabolism. Therefore, maintaining proper muscle mass and function is critical. Muscle incurs damage due to a variety of insults such as use, disuse, aging and pathology. While skeletal muscle does not undergo rapid turn-over under normal conditions, upon being damaged, it is capable of executing a robust regenerative response through mobilization of its resident progenitor cells, the satellite cells (Moss FP, Leblond CP, Anat Rec 170:421-436 (1970); Schultz E, Gibson MC, Champion T, J Exp Zool 206(3):451-6 (1978); Snow MH, Cell Tissue Res 186(3):535-40 (1978)). The self-renewal and differentiation capacity of the satellite cells have alluded to the archetypic "sternness," but their fate seems largely committed (Sinanan ACM, Buxton PG, Lewis MP, Bio Cell 98:203-214 (2006); Beauchamp JR et al., Cell Biol 151 : 1221-1234 (2000); Starkey JD et al., Histochem Cytochem 59(l):33-46 (2011)). In an adult, satellite cells comprise less than 5% of total nuclei on a myofiber; nevertheless, based on their proliferation kinetics and capacity, this is sufficient to regenerate an entire muscle (Schmalbruch H, Hellhammer U, Anat Rec 189: 169-176 (1977); Kelly AM, Dev Bio 65(1): 1-10 (1978); Gibson MC, Schultz E , Anat Rec 202(3) :329-337 (1982); Bischoff R in Myology, Vol 1, eds Engel AG, Franzini-Armstrong C (McGraw-Hill, Inc., New York), (1994); Zammit PS et al., Exp Cell Res 281 :39-49 (2002)).

Upon injury, skeletal muscle responds to damage in three distinct but overlapping phases:

degeneration; regeneration; and finally remodeling (Charge SBP, Rudnicki MA, Physiol Rev 84:209-238 (2004)). Immediately following the injury, inflammatory cells are recruited to the injury site to promote degeneration of the damaged tissue through necrosis and phagocytosis (Tidball JG, Am J Physiol Regul Integr Comp Physio 288:R345-353 (2005); McLennan IS, J Anat 188: 17-28 (1996); Pimorady-Esfahani A, Grounds MD, McMenamin PG, Muscle Nerve 20:158-166 (1997); Vierck J et al., Cell Bio Int 24:263-272 (2000); Arnold L et al., J Exp Med 204(5): 1057-1069 (2007)). The subsequent regenerative phase is characterized by mobilization of satellite cells, whereby the progenitor cells proliferate, differentiate and fuse to each other or to the existing fibers to regenerate the muscle (Zammit PS in Skeletal muscle repair and regeneration, eds Schiaffino S, Partridge T (Springer, Dordrecht (2008)). Finally, the contractile proteins are reassembled and function is restored during the remodeling phase.

When a compound includes more than one R', R", R'", or R"" group, for example, each of the R', R", R'", or R"" groups can be independently selected relative to the remaining R', R", R'", and R"" group(s).

Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloaliphatic, or heterocycloaliphatic groups. Such ring-forming substituents are typically, though not necessarily, attached to a cyclic base structure. In some embodiments, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring-forming substituents can attached to adjacent atoms of a cyclic base structure to create a fused ring structure. In other embodiments, the ring-forming substituents can be attached to a single atom of the base structure to create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent atoms of the base structure.

Unless otherwise stated, structures depicted herein are also meant to include all stereochemical forms of the structure; such as the R and S configurations for each asymmetric center, E and Z isomers for olefins, and/or the m and p configurations for each biaryl ring system. Therefore, single stereochemical isomers, as well as enantiomeric, diastereomeric, and atropisomeric mixtures of the present compounds are within the scope of the disclosure, as well as racemic mixtures. In some embodiments, the compounds disclosed herein are synthesized in or are purified to be in substantially enantiopure form, such as in a 90% enantiomeric excess, a 95% enantiomeric excess, a 97% enantiomeric excess or even in greater than a 99% enantiomeric excess, such as in enantiopure form.

Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms.

Where "heteroalkyl" is recited, followed by recitations of specific heteroalkyl groups, such as -NR'R" or the like, it will be understood that the terms heteroalkyl and -NR'R" are not redundant or mutually exclusive. Rather, the specific heteroalkyl groups are recited to add clarity. Thus, the term "heteroalkyl" should not be interpreted herein as excluding specific heteroalkyl groups, such as -NR'R" or the like.

The terms "cycloalkyl" and "heterocycloalkyl," by themselves or in combination with other terms, mean, unless otherwise stated, cyclic versions of "alkyl" and "heteroalkyl," respectively. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule.

A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring.

The term "heteroaryl" refers to aryl groups (or rings) that contain at least one heteroatom, typically N, O, and S. For certain embodiments, heteroatoms, such as the nitrogen and sulfur atoms, are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term "heteroaryl" includes fused ring heteroaryl groups (e.g. , multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring). A 5,6-fused ring heteroaryl refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring.

As used herein, the terms "co-administration," "administered in combination with," and their grammatical equivalents, are meant to encompass administration of two or more therapeutic agents to a single subject, and are intended to include treatment regimens in which the agents are administered by the same or different route of administration or at the same or different times. In some embodiments the one or more compounds described herein will be co-administered with other agents. These terms encompass administration of two or more agents to the subject so that both agents and/or their metabolites are present in the subject at the same time. They include simultaneous administration in separate compositions, administration at different times in separate compositions, and/or administration in a composition in which both agents are present. Thus, in some embodiments, the compounds described herein and the other agent(s) are administered in a single composition. In some embodiments, the compounds described herein and the other agent(s) are admixed in the composition. The term "effective amount" or "therapeutically effective amount" refers to the amount of an active agent (such as one or more compounds provided herein alone, in combination, or potentially in combination with other therapeutic agent(s)) sufficient to induce a desired biological result. That result may be amelioration or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. The term "therapeutically effective amount" is used herein to denote any amount of a therapeutic that causes an ameloriation, improvement and/or prevention in a disease condition. The amount can vary with the condition being treated, the stage of advancement of the condition, and the type and concentration of formulation applied. Appropriate amounts in any given instance will be readily apparent to those of ordinary skill in the art or capable of determination by routine experimentation.

The terms "prevent," "preventing" or "prevention," and other grammatical equivalents as used herein, include preventing additional symptoms, preventing the underlying metabolic causes of symptoms, inhibiting the disease or condition, e.g., arresting the development of the disease or condition and are intended to include prophylaxis.

III. Method of Making the Compounds

Disclosed compounds can be prepared to the carboxylic acid or hydroxamic acid at L ¹ respectively, as exemplified below and as will be understood by a person of ordinary skill in the art of organic synthesis. For the preparation of the corresponding salts, an additional step would be performed. An exemplary synthesis may include the following 1 ^st reaction step:

An alkylation reaction, specifically an etherification reaction, is performed where a hydroxyaryl or hydroxyheteroaryl moiety is reacted with an alkylating agent. For the hydroxyaryl or hydroxyheteroaryl moiety, the ring atoms are CR ^A or N; and R ^A is selected from H, D, F, CI, lower aliphatic or alkyl, -CD3, - CF3, -OH, -OCH3, -OCD3 or -OCF3. A suitable exemplary alkylating agent is an alkyl bromide Ri-O- L ¹ (CO)L ² -Br. The reactants are combined in the presence of a molar excess of a carbonate base (e.g. M = Na, K or Cs). The reaction is carried out in a polar aprotic solvent with a boiling point >100 °C such as DMF, DMA or DME. Typical reaction concentrations are 0.1 to l .OM. Reactants are heated to >100 °C, under ambient or elevated pressure, such as with microwave assisted organic synthesis (MAOS), for a period of time ranging from minutes to hours until both reactants are consumed. Exemplary aldehydes include:

Exemplary linkers include:

where m and n independently are selected from a range of 1-6 and R ¹ (referred to herein as R ^1A ) is aliphatic, typically alkyl. Generally the distance between the bromide and the carbonyl carbon is 4-8 carbon-carbon bond lengths. Isolation, purification and characterization of the product aldehyde would be consistent with that typically practiced by one of ordinary skill in the art.

An exemplary 2 ^nd step of the reaction process is provided below:

The 2 ^nd reaction step is generally characterized as a reductive animation reaction of an aldehyde and primary amine, such as R ³ -L ⁴ -NH2, where the reducing nucleophile is L ³ . L ³ can be -H, -D, -CH3, aliphatic, typically alkyl, and more typically lower alkyl. In certain embodiments, the L ³ reducing agent is a deuterated reducing agent such as, but not limited to, diborane-d6, sodium borodeuteride, sodium cyanoborodeuteride and deuterium. The reaction conditions are performed so that monoalkylation is the major product and over alkylation to the tertiary amine is suppressed. Reducing agents and co-solvent reaction additives are numerous, but readily known to those of ordinary skill in the art. Some exemplary primary amines comprising R ³ and L ⁴ functionalities include:

Solvents typically are chlorinated hydrocarbons, such as CH2CI2, CHCI3, or 1 ,2-dichloroethane. Reaction temperature and reaction time vary depending on the reaction temperature selected. As described above, MAOS versions of reductive animation exist.

The 3 ^rd reaction step is generally characterized as a secondary amine acylation reaction. Exemplary acylating reagents include 4-bromobenzoyl or 4-bromoheteroaryoyl compounds. X typically is a leaving group, such as F, CI, OTf, or similar favorable leaving group.

Ai, A ₂ , A ₃ , and A ₄ are bonded by a single or double bond such that the resulting ring is aromatic; Ai, A ₂ , A ₃ , and A ₄ are independently selected from -CR ¹² or N; R ¹² is selected from H, D, F, CI, lower alkyl, - CD3, -CF3, -OH, -OCH3, -OCD3 or -OCF3. Representative examples include:

Typical reagent conditions include using a base, typically a non-nucleophillic base, or a hindered base having attenuated nucleophilicity, in excess molar amounts. Hindered amine bases, such as Hunig' s base (Ν,Ν-diisopropylethylamine), would be a suitable choice, as will be recognized by a person of ordinary skill in the art. Solvents typically are chlorinated hydrocarbons, such as CH ₂ CI ₂ , CHCI ₃ , or 1,2- dichloroethane. Reaction temperature and reaction time vary depending on the reaction temperature selected. As described above, MAOS versions of secondary amine acylation exist.

The 4 ^th reaction step is generally characterized as a biaryl, aryl-heteroaryl or heteroaryl-heteroaryl coupling reaction mediated catalytically by a transition metal or transition metal complex.

Numerous coupling reactions are known to those of ordinary skill in the art. In this embodiment, the coupling reaction could be the Suzuki-Miyaura cross-coupling where X is boronate -B(OH) ₂ , M is palladium, L is triphenylphosphine (PPI13), and n is 4. With Pd(PPli3)4 as the catalyst, the cross-coupling reaction would be carried out in the presence of a base, such as a Na, K or Cs carbonate, in a ternary solvent system of DME, EtOH and Water. R ² may be any aryl, aryl, heteroaryl, heteroaryl boronic acid, boronate ester or potassium trifluroboronate salt in this cross-coupling example. Exemplary R ² moieties include:

Reaction temperature and reaction time vary depending on the reaction temperature selected. As described above, MAOS versions of cross-coupling reactions exist.

The final step of this exemplary reaction sequence is saponification of R ¹ where L ¹ is a bond, thereby converting the carboxylic ester to the carboxylic acid. Where L ¹ is nitrogen, R ¹ is deprotected to the hydroxamic acid according to methods known to those of ordinary in the art. This reaction step is as follows:

Typically the base is a hydroxide salt, such as Li, Na, K or Cs hydroxide. Suitable solvents include, but are not limited to, water, THF, alcohols, such as methanol, ethanol, propanol or isopropanol, DMF, DMSO, or any combination thereof. Reaction temperature and reaction time vary depending on the reaction temperature selected. As described above, MAOS versions of saponification reactions exist.

Additional formulation of these compounds include converting the carboxylic acid or hydroxamic acid versions to their complimentary pharmaceutically relevant salts. The various methods for salt formation are known to a person of ordinary skill in the art. An exemplary scheme is provided below.

B. Excipients and Dosage Forms

The present disclosure provides pharmaceutical compositions that include a prophylactically or therapeutically effective amount of one or more disclosed compounds (such as 1, 2, 3, 4 or 5 disclosed compounds) in admixture with at least one pharmaceutically acceptable material, such as an excipient.

Disclosed pharmaceutical compositions include a detectable amount of the PPAR agonist, such as greater than 0% to less than 100%, such as from 5% to 99%, or from about 50% to about 99%, or from 25% to about 99% by weight of the PPAR agonist of the present disclosure.

Disclosed compositions can be administered in any suitable dosage form, such as tablets, pills, capsules, powders, granules, sterile solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, auto-injector devices or suppositories. The compositions are intended for any suitable administration route, including oral, parenteral, intranasal, sublingual, rectal, transdermal, inhalation or insufflation. The compositions may be formulated by methods known by those of ordinary skill in the art, such as described in Remington's Pharmaceutical Sciences (15th ed., Mack Publishing Company, Easton, Pennsylvania, 1980).

The compositions can be administered for therapeutic or prophylactic treatments. In therapeutic applications, compositions are administered to a subject suffering from a disease (e.g., a PPAR5 related disease) in a "therapeutically effective dose." Amounts effective for this use can depend upon the severity of the disease and the general state of the subject's health. Single or multiple administrations of the compositions can be administered depending on the dosage and frequency as required and tolerated by the subject. Also, the composition, shape, and type of dosage forms may vary depending on their use. For example, a dosage form used for acute treatment of a disease or disorder may contain larger amounts of the active ingredient than a dosage form used in the chronic treatment of the same disease or disorder.

Similarly, a parenteral dosage form may contain smaller amounts of the active ingredient than an oral dosage form.

Oral dosage forms include, but are not limited to, tablets (including without limitation scored or coated tablets), pills, granules, lozenges, caplets, capsules, chewable tablets, powder packets, cachets, troches, wafers, aerosol sprays, mucosal patches, or liquids, such as syrups, elixirs, solutions or suspensions in an aqueous liquid, for example water or saline, a non-aqueous liquid, an oil-in-water emulsion, or a water- in-oil emulsion. Typical oral dosage forms may be prepared by combining the pharmaceutically acceptable PPAR agonist, potentially in a liquid, solid, granule or gelatin for and/or in a salt form, in admixture with at least one excipient including, but are not limited to, surface stabilizers, dispersion aids, binders, filling agents, lubricating agents, glidants, suspending agents, sweeteners, flavoring agents, preservatives, buffers, wetting agents, disintegrants, effervescent agents, humectants, controlled release agents, absorption accelerators, absorbents, plasticizers, lactose, sucrose, mannitol, sorbitol, calcium phosphates, corn starch, potato starch, cellulose, hydroxy propyl methyl cellulose, microcrystalline cellulose, gelatin, acacia, sodium alginate, alginic acid, tragacanth, guar gum, gelatin, colloidal silicon dioxide, talc, magnesium stearate, stearic acid, colorants, diluents, talc, calcium carbonate, kaslin, maltodextrin, polymethacrylates, moistening agents, preservatives, dyes, and any combination thereof.

Disintegrants facilitate producing tablets that disintegrate when exposed to an aqueous environment. The amount of disintegrant used varies based upon the type of formulation and mode of administration, and is readily determined by a person of ordinary skill in the art. Typical pharmaceutical compositions comprise from about 0.5 to about 15 weight percent of disintegrant, such as from about 1 to about 5 weight percent of disintegrant. Disintegrants include, but are not limited to, agar-agar, alginic acid, guar gum, calcium carbonate, microcrystalline cellulose, croscarmellose sodium, carboxymethylcellulose calcium,

methylcellulose, crospovidone, polacrilin potassium, sodium starch glycolate, potato or tapioca starch, other starches, pre-gelatinized starch, clays, other algins, other celluloses, gums, and mixtures thereof.

Exemplary lubricants include, but are not limited to, calcium stearate, magnesium stearate, mineral oil, light mineral oil, glycerin, sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid, sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g. , peanut oil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, and soybean oil), sodium benzoate, sodium stearylfumarate, zinc stearate, ethyl oleate, ethyl laureate, agar, syloid silica gel, synthetic silica, and mixtures thereof. Lubricants typically are used in an amount of less than about 1 weight percent of the pharmaceutical compositions.

Disclosed PPAR agonists, and related forms, such as salts, can be administered as controlled- or delayed-release formulations. Controlled-release pharmaceutical products have a common goal of improving drug therapy over that achieved by their non-controlled release counterparts. These dosage forms can be used to provide slow or controlled-release of one or more active ingredients using, for example, alginic acid, aliphatic polyesters, bentonite, cellulose acetate, phthalate, carnuba wax, chitosan,

ethylcellulose, guar gum, microcrystalline wax, paraffin, polymethacrylates, povidone, xanthan gum, yellow wax, carbomers, hydroxypropylcellulose, and hydroxypropylmethylcellulose.

Pharmaceutical compositions can also include large, slowly metabolized macromolecules such as proteins, polysaccharides, such as chitosan, polylactic acids, polyglycolic acids and copolymers (such as latex functionalized sepharose(TM), agarose, cellulose, and the like), polymeric amino acids, amino acid copolymers, and lipid aggregates (such as oil droplets or liposomes). Additionally, these carriers can function as immunostimulating agents (i.e. , adjuvants).

The compositions provided herein, alone or in combination with other suitable components, can be made into aerosol formulations (e.g. , they can be "nebulized") to be administered via inhalation. Aerosol formulations can be placed into pressurized acceptable propellants, such as dichlorodifluoromethane, propane, nitrogen, and the like.

Suitable formulations for rectal administration include, for example, suppositories. Exemplary suppositories include a suppository base, such as natural or synthetic triglycerides or paraffin hydrocarbons. Gelatin rectal capsules include a combination of the compound of choice with a base, including, for example, liquid triglycerides, polyethylene glycols, and paraffin hydrocarbons.

Topical dosage forms include, but are not limited to, creams, lotions, ointments, gels, shampoos, sprays, aerosols, solutions, emulsions, and other forms know to a person of ordinary skill in the art. Suitable formulations include, without limitation, solutions, suspensions, emulsions, creams, ointments, powders, liniments, and salves. Transdermal and mucosal dosage forms can include, but are not limited to, ophthalmic solutions, patches, sprays, aerosols, creams, lotions, suppositories, ointments, gels, solutions, emulsions, or suspensions. Dosage forms suitable for treating mucosal tissues within the oral cavity can be formulated as mouthwashes, as oral gels, or as buccal patches.

The disclosed PPAR agonists can be formulated for parenteral administration, such as, for example, by intraarticular (in the joints), intravenous, intraarterial, intramuscular, intratumoral, intradermal, intraperitoneal, and subcutaneous routes. Examples of parenteral dosage forms include, but are not limited to, solutions ready for injection, dry products ready to be dissolved or suspended in a pharmaceutically acceptable vehicle for injection, suspensions ready for injection, and emulsions. In addition, controlled- release parenteral dosage forms can be prepared. Suitable materials for such administration include sterile water; saline solution; glucose solution; aqueous vehicles, such as sodium chloride Injection, Ringer's Injection, Dextrose Injection, Dextrose, Sodium Chloride Injection, Lactated Ringer's Injection; ethyl alcohol, polyethylene glycol, and propylene glycol; non-aqueous vehicles such as, but not limited to, corn oil, cottonseed oil, peanut oil, sesame oil, ethyl oleate, isopropyl myristate, and benzyl benzoate; aqueous and non-aqueous, isotonic sterile injection solutions, which can contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. In the practice of this disclosure, compositions can be administered, for example, by intravenous infusion, orally, topically, intraperitoneally, intravesically or intrathecally. In an independent embodiment, parenteral administration, oral administration, and/or intravenous administration are the methods of administration. The formulations of compounds can be presented in unit-dose or multi- dose sealed containers, such as ampules and vials.

The pharmaceutical preparation can be in unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packaged tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

The combined administrations contemplate co-administration, using separate formulations or a single pharmaceutical formulation, and consecutive administration in either order, wherein, in some embodiments, there is a time period while both (or all) active agents simultaneously exert their biological activities.

The particular mode of administration and the dosage regimen will be selected by the attending clinician, taking into account the particulars of the case (e.g. the subject, the disease, the disease state involved, the particular treatment, and whether the treatment is prophylactic). Treatment can involve daily or multi-daily or less than daily (such as weekly or monthly etc.) doses over a period of a few days to months, or even years. For example, a therapeutically effective amount of one or more compounds disclosed herein can be administered in a single dose, twice daily, weekly, or in several doses, for example daily such as two, three or four times daily, or during a course of treatment. The disclosed PPAR agonists may be administered substantially continuously too, such as by using a transdermal delivery system. In a particular non-limiting example, treatment involves once daily dose or twice daily dose. However, a person of ordinary skill in the art would immediately recognize appropriate and/or equivalent doses looking at dosages of approved compositions for treating a PPAR5 related disease using the disclosed PPAR agonists for guidance.

The pharmaceutical compositions that include one or more compounds disclosed herein can be formulated in unit dosage form, suitable for individual administration of precise dosages. In one non- limiting example, a unit dosage contains from about 1 mg to about 50 g of one or more compounds disclosed herein, such as about 10 mg to about 10 g, about 100 mg to about 10 g, about 100 mg to about 7 g, about 200 mg to about 10 g, or about 200 mg to about 5 g. In other examples, a therapeutically effective amount of one or more compounds disclosed herein is from about 0.01 mg/kg to about 500 mg/kg, for example, about 0.5 mg/kg to about 500 mg/kg, about 1 mg/kg to about 100 mg/kg, or about 1 mg/kg to about 50 mg/kg. In other examples, a therapeutically effective amount of one or more compounds disclosed herein is from about 1 mg/kg to about 20 mg/kg, such as about 2 mg/kg to about 5 mg/kg. In some embodiments, about 3 mg/kg or 10 mg/kg can be used.

V. Methods

Provided herein are methods of activating PPAR8. Such methods can include contacting a PPAR8 protein with an effective amount of a compound or composition provided herein, thereby activating PPAR8. In some embodiments, the contacting is performed in vitro. In other embodiments, the contacting is performed within a subject, such as a human or other mammalian subject (such as a veterinary subject, for example a cat, dog, mouse, or rat), for example by administering a PPAR agonist disclosed herein to the subject. In some embodiments, the compound or composition is administered ton a healthy subject. In some embodiments, the subject is a sedentary or immobilized subject. In other embodiments, the subject is an exercising subject, such as one who exercises for at least 20 minutes, at least 30 minutes, at least 45 minutes, or at least 60 minutes, at least 2, at least 3, or at least 4 days per week. In some embodiments, a healthy subject is also an exercising subject.

In some examples, contacting a PPAR8 protein in vitro or in vivo with an effective amount of one or more compounds or compositions provided herein, increases PPAR5 activity by at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 100%, at least 200%, at least 300%, at least 400%, or even at least 500%, for example as compared to an amount of PPAR8 activity in the absence of the compound/composition. Methods of measuring PPAR5 activity are known, and specific examples are provided herein (e.g., measuring expression of PPAR5 at the protein or nucleic acid level, measuring Beta oxidation levels, creatine kinase levels, pentose phosphate shunt in liver, blood glucose levels and methods provided in Wang et al., PLos Biol. 2(10):e294, 2004 and Lee et al, PNAS 103:3444-9, 2006).

In some embodiments, the subject recovers from acute injury following administration of the PPAR agonist.

In some embodiments, activating PPAR8 within the subject by administration of a PPAR agonist disclosed herein (or composition containing the PPAR agonist) increases or maintains muscle mass or muscle tone (such as a skeletal or cardiac muscle) in the subject (such as in a healthy subject or a sedentary subject). For example, activating PPAR8 within the subject can increase muscle mass, muscle tone, or both, in the subject. In some examples, administering an effective amount of one or more PPAR agonist compounds or compositions provided herein increases muscle mass, muscle tone, or both, by at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 100%, at least 200%, at least 300%, at least 400%, or even at least 500%, for example as compared to an amount of PPAR8 activity in the absence of the compound/composition. Methods of measuring muscle mass and muscle tone are known, and specific examples are provided herein (e.g., see methods provided in WO 2009/086526).

In other embodiments, activating PPAR8 within the subject (such as a healthy subject or a sedentary subject) maintains muscle mass, muscle tone, or both, in the subject. In some examples, administering an effective amount of one or more PPAR agonist compounds or compositions provided herein maintains muscle mass, muscle tone, or both, such that the amount of muscle mass, muscle tone or both, does not change by more than 1%, for example no more than 2%, no more than 3%, no more than 4%, no more than 5%, no more than 6%, no more than 7%, no more than 8%, no more than 9%, no more than 10%, or no more than 15%, for example as compared to an amount of muscle mass, muscle tone, or both in the absence of the compound/composition. Methods of measuring muscle mass and muscle tone are known, and specific examples are provided herein (e.g., see methods provided in WO 2009/086526).

Thus, the disclosed PPAR agonists and compositions containing such can be used to increase or maintain muscle mass or muscle tone (or both) in a subject. For example, the disclosed PPAR agonists and compositions containing such can be used to increase or maintain muscle mass or muscle tone (or both) in a subject following an injury, following a period of immobilization (for example confinement to a bed or wheelchair) or immobilization of a body part (for example immobilization of an appendage or joint due to a broken bone, joint replacement, tendon tear, surgery, and the like), which events can result in a loss of muscle mass and/or muscle tone. The method includes administering to the subject a therapeutically effective amount of one or more compounds provided herein. In some embodiments, the subject is a sedentary or immobilized subject. In other embodiments, the subject is an exercising subject.

Methods of treating or preventing a PPAR8-related disease or condition in a subject in need thereof are provided. The methods can include administering to the subject a therapeutically effective amount of one or more compounds or compositions provided herein. In some embodiments, the PPAR8-related disease is a vascular disease (such as a cardiovascular disease or any disease that would benefit from increasing vascularization in tissues exhibiting impaired or inadequate blood flow). In other embodiments, the PPAR8- related disease is a muscular disease, such as a muscular dystrophy.

Thus, in some examples, the subject treated has or is at risk for developing one or more of these diseases.

VI. Working Examples

Skeletal muscle relies on the resident progenitor cells, the satellite cells, for postnatal growth and regeneration. Therefore, maintaining an adequate number and proper function of satellite cells is critical for muscle to appropriately response to damage. While endurance exercise promotes adaptive responses in the muscle, including an increase in the satellite cell number, it is not known whether transcriptionally directed "endurance exercise training" has similar effects. Here it is shown that mice harboring constitutively active PPAR8 in skeletal muscle displayed an accelerated regenerative process in muscle after an acute injury. Gene expression analyses showed earlier resolution of the inflammatory response and induction of myogenic markers, indicating that PPAR8 activation induces a temporal shift in the regenerative process. Notably, a significant increase in the number of satellite cells was found in mice with constitutively active PPAR8 expressed in skeletal muscle, consistent with the observed increase in proliferating cell number after the injury. PPAR5 activation induced the expression of FGF1, which is known to be involved in muscle development and regeneration. In particular, PPAR5 up-regulates FGFla isoform, which may be responsible for supporting cell proliferation and reestablishment of vasculature to augment the regenerative process. Furthermore, the restoration of fiber integrity was improved in wild-type mice after acute treatment with the PPAR5 synthetic ligand, GW501516. Collectively, these findings allude to the therapeutic potential of PPAR8, to accelerate the recovery from acute muscle injury. GW501516 is 4-[({4-methyl-2-[4- (trifluoromethyl)phenyl]-l,3-thiazol-5-yl}methyl)sulfanyl]-2 -methylphenoxy}acetic acid (also known as "GW501516," "GW-501,516," "GW1 " "GW" or GSK-516), and has a structure:

Activation of peroxisome proliferator activated receptor δ (PPAR5) induces a fiber type switch toward a more oxidative phenotype, altering both metabolic and functional output of the muscle (Wang et al., PLoS Biol 2(10):e294. Erratum in: PLoS Biol. 2005 Jan;3(l):e61 (2004); Luquet et al , FASEB J 17(15):2299-2301 (2003)). Specifically, PPAR5-mediated muscle remodeling translates into supernatural physical endurance, and protection against diet-induced obesity and symptoms of metabolic disorders that ensue (Wang et al. , PLoS Biol 2(10):e294. Erratum in: PLoS Biol. 2005 Jan;3(l):e61 (2004); Wang et al. , Cell 113: 159-170 (2003)). Furthermore, pharmacological activation of PPAR5 and exercise training synergistically enhance oxidative fibers and running endurance (Narkar VA et al, Cell 134(3):405-415 (2008)). Exercise confers a myriad of healthful benefits to the body, including improvement of atrophic and disease conditions (Nicastro et al, Braz J Med Biol Res 44( 11 ) : 1070-9 (2011 ) ; Markert et al. , Muscle Nerve 43(4):464-78 (2011)). Recently, endurance exercise alone has been shown to improve ageing induced decrease in satellite cell number and their myogenic capacity (Shefer et al, PLoS One 5(10):el3307 (2010)).

It is demonstrated herein that both genetic and pharmacological activation of PPAR5 promote muscle regeneration in an acute thermal injury mouse model. PPAR5 activation during regeneration expedites resolution of inflammatory response and restoration of contractile proteins. Interestingly, acute pharmacological activation of PPAR5 by oral administration of a synthetic ligand, GW501516, is sufficient to confer similar benefits during muscle regeneration after an acute injury. Based on these observations, a novel role of PPAR5 during adult muscle regeneration and its use as a therapeutic target to enhance regenerative efficiency of skeletal muscle is provided.

EXAMPLE 1

Experimental Procedures

A. Animals

VP16-PPAR5 mice (Wang et al , Cell 113: 159-170 (2003)) were bred to CB6F1 strain (Jackson Laboratories) and used as heterozygotes in experiments. The non-transgenic littermates served as controls. All experiments were performed when animals were 8 weeks of age. Nestin-GFP mice (Mignone et al. , Comp Neurol 469(3):311-324 (2004)) were kindly provided by Dr. Fred Gage at the Salk Institute for Biological Studies. B. Freeze burn injury

Tibialis anterior (TA) muscles were injured according to previously published methods with a few modifications (Brack et ah, Science 317(5839):807-810 (2007)). A stainless steel lg weight (Mettler- Toledo) equilibrated to the temperature of dry ice was placed directly on the exposed TA for 10 seconds. Following the thermal injury, incision was closed using VetBond (3M). All injury procedures were performed on the left leg, and the right leg was used as control.

C. Histology

Animals were perfused with 15 mL of ice-cold PBS followed immediately by 20 mL of 10% saline buffered formalin. TA muscles were excised and immersed in 4% paraformaldehyde for at least 48 hours at

4 °C. Tissues were dehydrated by exposure to a series of solutions with increasing percentage of ethanol.

Dehydrated tissues were cleared in xylene and allowed for paraffin to permeate over night at 60 °C. Tissues were then embedded in plastic molds.

Paraffin embedded tissue blocks were sectioned at 7 μιη thick on Leica Jung 2500 Microtome. Sections were stained with hematoxylin and counter stained with 1% eosin. Slides were dried and mounted with Entellan mounting media (EMS). Three random non-overlapping fields were photographed for analysis. Regenerating fiber number was measured by counting the number of discernible muscle fibers with centralized myonuclei (Ge et ah, Am J Physiol Cell Physiol 297(6):C1434-1444 (2009)). Regenerating fiber cross sectional area (CSA) was measured using Image J software.

D. Evans Blue dye staining

Injured animals were injected with Evans Blue dye according published protocol (Hamer et al , J Anat 200(Pt l):69-79 (2002)). Sterile 1% w/v Evans Blue dye in PBS was intraperitoneally injected at 1% volume relative to the body mass of an animal. 7 hours after the injection, injured TA muscles were harvested and snap-frozen by isopentane quenching in liquid nitrogen. Frozen sections were cut in ΙΟμιη thickness, fixed in ice-cold acetone, dipped in xylene and mounted with DPX. Proportion of the stained area over the total area was measured using ImageJ software.

E. BrdU Labeling

50 mg/kg body weight of BrdU (Sigma) was injected intraperitoneally as solution of 10 mg/mL BrdU in saline. TA muscles were harvested at 7 days after injury and processed for paraffin sections as described above. BrdU incorporation was visualized using the BrdU Labeling and Detection Kit I (Roche) and BrdU+ nuclei were counted and represented as a proportion of total nuclei in a field. F. RT-QPCR

Whole or partial tissues were homogenized by Polytron probe homogenizer in Trizol reagent (Invitrogen). Total RNA was extracted from the homogenates according to the manufacturer's protocol. 1 μg of DNase-treated total RNA was reverse transcribed using Superscript II Reverse Transcriptase

(Invitrogen) according to the manufacturer's instructions. cDNAs were diluted 1/40 with ddELO and used as templates in RT-QPCR reactions with SYBRGreenER qPCR SuperMix detection system (Invitrogen). Samples were prepared in technical triplicates and relative mRNA levels were calculated by using the standard curve methodology and normalized against GAPDH mRNA levels in the same samples. G. My ofiber Isolation

Either whole or partial gastrocnemius muscle was digested in 2% collagenase I (Sigma) in DMEM with 10% FBS for 60 minutes at 37 °C. Muscle tissue was further mechanically dispersed by triturating in a fire polished wide bore Pasteur pipet. Liberated fibers were washed in two changes of PBS with 10%FBS and finally mounted on glass slides with Vectashield mounting media (Vector Labs).

H. Isolation of satellite cells

Satellite cells were harvested from TA of 8 weeks old animals according to published protocols with some modifications (Day et al. (2007) Nestin-GFP reporter expression defines the quiescent state of skeletal muscle satellite cells. Dev Biol 304(1) :246-259). Muscles were removed and washed briefly in DMEM on ice. They were then minced into a fine slurry with a razor blade on a 60mm culture dish over ice. Minced muscles were transferred to one well of a 6-well plate containing 5 ml of 450KPU/ml pronase in DMEM. The tissues were digested at 37°C/5% CO ₂ for 60 minutes. After digestion, tissues were vigorously triturated 20 times through 10ml serological pipet. Digested tissues were filtered through a 40 micron cell strainer and washed with an equal volume of DMEM with 20% horse serum. Cells were spun down at lOOOg for 10 minutes and resuspended in sorting buffer (DMEM with 10% FBS). Cells were separated from larger debris using a 20%/60% Percoll gradient (Yablonka-Reuveni Z et al. (1987) Isolation and clonal analysis of satellite cells from chicken pectoralis muscle. Dev Bio 119: 252-259). GFP positive cells were sorted on BD FACSAria II sorter.

EXAMPLE 2

Muscle specific activation of PPAR5 confers regenerative advantage

While it has been shown that the majority of the metabolic genes are down regulated in injury, PPAR5 expression was induced over 2 fold at 2 days after the injury (Warren et al. (2007) Mechanisms of skeletal muscle injury and repair revealed by gene expression studies in mouse models. J Physiol. 582.2: 825-841, FIG. 1A). This injury dependent up-regulation of PPAR5 strongly suggested a possible role for PPAR5 during the early part of the regenerative process.

Freeze burn injury was used to elicit the regenerative program, which has been shown to model the standard course of the regenerative response, including satellite cell activation (Karpati and Molnar. "Muscle fibre regeneration in human skeletal muscle diseases." In: Schiaffino S, Partridge T (eds). Skeletal muscle repair and regeneration. Springer, Dordrecht, 2008). Additionally, since the injury is directly applied to the surface of the muscle, it is highly localized and reproducible.

Using Evans Blue dye uptake as a marker of myofiber damage, fiber integrity was histologically assessed. The freeze burn injury does not incapacitate the animals and the damaged fibers restore original cross sectional area by 21 days after the injury (FIG. 1J).

By comparing the proportion of stained fibers within the cross sectional area (CSA) of the injured muscle 5 days after the injury, the degree of damage was quantified. At 5 days after the injury, VP16- PPAR5 (TG) animals show significantly less dye uptake, indicative of enhanced fiber regeneration, over the wildtype (WT) animals (FIG. 1C and D). While 14% of the total CSA shows dye uptake in WT muscle, only 5% of the total CSA of TG muscle show dye uptake (n=8 WT; n=5 TG; p=0.001) (FIG. ID). At 12 and 36 hours after the injury, however, both WT and TG animals showed similar proportions of stained area (50.6% and 47.4% (p=0.67), and 38.5% and 43.3% (p=0.23), respectively) (FIGS. IE and IF). Similar level of dye uptake shortly after the injury shows that both WT and TG animals initially sustain similar degree of damage from the injury and suggests that PPAR5 activation does not confer protection from damage.

Instead, the reduction in Evans Blue dye uptake observed 5 days after the injury suggests that the muscle specific PPAR5 activation promotes restoration of fiber integrity after the injury.

The morphological hallmarks of regenerating fibers were determined for a detailed analysis of the process. H&E stained transverse sections through the injured area were examined at 3, 5 and 7 days post injury. At 3 days after the injury, both WT and TG animals showed similar degrees of degeneration defined as necrosing fibers surrounded by infiltrating monocytes (FIG. 1G). No regenerating fibers, characterized by a small round shape and centralized nuclei, were discernible at 3 days in WT animals, but a notable few were seen in TG animals (arrows, FIG. 1G). By day 5 after the injury, obvious differences are seen. In WT animals, small regenerating fibers were visible but necrosing fibers and monocytes were still prevalent at the site of the injury (arrowheads, FIG. 1G). While in the TG animals, the injury site shows an orderly arrangement of small regenerating fibers. Quantification of regenerating fiber number and CSA reveals that by 5 days post injury, TG animals show significant regenerative advantage over their WT counterparts. Both CSA of the regenerating fibers and the number of regenerating fibers were significantly greater for TG animals at 43.5% (n=5 or 6; p<0.03) and 33.0% (n=l l or 12; p<0.001), respectively (FIGS. 1H and II). By day 7 post injury, the damage site appears architecturally similar between WT and TG animals, where both show a field of immature regenerating fibers without the infiltrating immune cells. However, quantification of the regenerating fibers revealed a regenerative advantage of the TG animals in the number of nascent regenerating fibers (FIG. 1H). At 21 days after the injury, both WT and TG animals have restored their fiber size and number to that of the uninjured level (FIG. 1J). These data demonstrate that the muscle specific activation of PPAR5 bestows significant regenerative advantage, most prominently observed in the early stages of the regenerative process.

EXAMPLE 3

PPAR5 activation leads to temporal shift, thus increased efficiency,

of the muscle regenerative process

Skeletal muscle regeneration is an intricately orchestrated process involving a variety of cell types. For example, immune cells, both neutrophils and macrophages, are necessary for the proper progression of regenerative process (Zacks et al , Muscle Nerve 5: 152-161 (1982); Grounds et al, Cell Tissue Res 250:563-569 (1987); Teixeira et al , Muscle Nerve 28(4):449-459 (2003); Summan et al. , Am J Physiol Regul Integr Comp Physiol 290:R1488-R1495 (2006); Contreras-Shannon et al. , Am J Physiol Cell Physiol 292:C953-967 (2007); Segawa et al. , Exp Cell Res 314(17): 3232-3244 (2008)). Additionally, various cytokines are necessary to promote chemotaxis of monocytes and also to directly regulate the activities of myogenic cells (Warren et al. , Am J Physiol Cell Physiol 286(5):C1031-1036 (2004); Yahiaoui et al., J Physiol 586:3991-4004 (2008); Chazaud et al., JCB 163(5): 1133-1143 (2003)). Therefore, the temporal expression profiles of genes associated with various aspects of the regenerative process were determined.

Global, injury-specific gene expression changes were identified in TA muscles by niicroarray. Comparing the gene expression profiles of injured TG and WT muscle 3 days post-injury, 3257 genes with altered expression were identified, of which 1375 were down regulated and 1882 were up regulated.

Notably, genes involved in myogenesis and remodeling were robustly up-regulated by PPAR5 activation while those involved in inflammatory response were down regulated in injured TG muscles (FIG. 2A and B). Additionally, genes involved in developmental processes, angiogenesis and anti-apoptotic processes emerged from the analysis (FIG. 2A). Relative expressions of regeneration markers reveal down-regulation of early makers (inflammatory genes) and up-regulation of regenerative/remodeling genes (myogenic, vascularization, ECM genes) in TG animals 3 days post injury (FIG. 2B). Collectively, PPAR5 activation appears to control a network of genes directly involved in myogenesis, as well as genes involved in remodeling and the repair processes after an injury.

Underlying the phasic progression of the regenerative program is a temporally coordinated program of gene expression changes that affect a variety of contributing processes. In order to validate and temporally-expand the niicroarray data, expression of CD68 (an inflammation marker) and MyoD (a marker of myogenesis) were measured by Q-PCR at several time points over the 7 day period post injury (FIGS. 2C and 2D). A temporal shift in the expression patterns of regenerative markers for TG animals compared to their WT littermates was observed. TG animals showed a rapid, most robust induction of CD68, that was subsequently down regulated earlier than in the WT animals. Interestingly, inflammatory markers studied here peaked at similar levels between the two genotypes, which indicates that TG animals do not completely suppress their inflammatory responses. Instead, it appears that the TG animals resolve the inflammatory responses more efficiently, which is consistent with the accelerated restoration of muscle morphology observed. TG animals also show higher expression of perinatal myosin heavy chain gene, Myh8, at 7 days post injury, indicating more efficient reassembly of the contractile properties (FIG. 2E). PPAR5 activation leads to a temporal shift in the expression patterns of regenerative markers, which together with the histology data, shows a role of PPAR5 in increasing regenerative efficiency.

EXAMPLE 4

PPAR5 directs neo- vascularization via regulation of FGF1

This example describes adaptive responses bestowed by PPAR5 activation in the muscle which may contribute to the observed beneficial effects on regeneration.

Increased vasculature is one of the hallmarks of oxidative myofibers, which facilitates introduction of immune cells and also supports increased number of satellite cells. TG animals show increased expression of FGF1 in TA muscle (FIG. 3D). Immunostaining transverse sections of uninjured TA from WT and TG animals revealed a 36% increase in the number of CD31+ capillaries per field upon PPAR5 activation (FIGS. 3A-B), as well as a significant increase in the expression of FGFla. Furthermore, 5 days after injury, TG animals show increased expression of CD31 , which is indicative of increased vascularity (FIG. 3E-F). Notably, FGFla is a direct PPAR5 target gene, as demonstrated by the PPAR5 response element (PPRE) -dependent activation with the PPAR5 ligand, GW501516, in a luciferase reporter assay (FIG. 3G). FGF1 has been shown to be expressed in regenerating fibers in chronic disease models and has been implicated in myogenesis and regeneration (Oliver, Growth Factors. 1992;7(2):97-106, 1992; Saito, 2000, Muscle Nerve. 23(4):490-7). In addition, FGF1 increasing the microvasculature in adipocytes and PPAR5 has been shown to directly regulate the expression of FGFla isoform (Jonker et al, Nature.

485(7398):391-4, 2012). Therefore, the increased vascularity induced by PPAR5 may contribute to the accelerated regenerative process observed in VP16-PPAR5 animals.

EXAMPLE 5

PPAR5 activation positively regulates quiescent satellite cell number One of the first events following the injury is the proliferation of muscle resident progenitors, the satellite cells. This example describes results showing that the regenerative advantage observed in TG animals could be due to altered satellite cell homeostasis.

Nestin expression was used as a marker of satellite cells, and nestin-GFP;VP16-PPAR5 double transgenic animals were used to genetically label quiescent satellite cells (SCs) in vivo (Mignone et al. , Comp Neurol 469(3):311-324 (2004); Day et al, Dev Biol 304(1) :246-259 (2007)). Gastrocnemius muscles were enzymatically digested to liberate individual fibers, then mounted for quantification (FIG. 4A). While double transgenic animals averaged 1.01 SCs per mm of fiber length, GFP+ animals only had 0.15 SCs per mm, a 6.48 fold higher SC content on VP16- PPAR5 muscle fiber (FIG. 4B).

Satellite cell activity was measured as myoblast proliferation elicited by the freeze burn injury in vivo. After the freeze burn injury, BrdU was intraperitoneally injected at 12 hrs, 24 hrs and 2 days after the injury, and the muscles were harvested 7 days after the injury. The ratio of BrdU+ to total nuclei was calculated to determine the number of proliferating cells. TG animals showed 40-60% increase in the number of BrdU+ proliferating cells at all three injection times (FIG. 4C). These results are consistent with the PPAR5-induced increase in the number of quiescent satellite cells yielding higher numbers of fusion competent myoblasts, leading to the enhancement of regenerative capacity of the muscle. Interestingly, neither endogenous PPAR5, or the constitutively activate VP16-PPAR5, are significantly expressed in satellite cells (FIG. 4D and E), indicating that the increase in satellite cell number in the TG muscle is an indirect consequence of PPAR5 activation in muscle.

EXAMPLE 6

Acute pharmacological activation of PPAR5 confers a regenerative advantage

Pharmacological activation of PPAR5 has been shown to induce PPAR5 target genes in fast-twitch hind limb muscles (Narkar et al , Cell 134(3):405-415 (2008)). To demonstrate that an acute

pharmacological activation of PPAR5 can modulate the regenerative process after injury, C57BL6J mice were treated with GW501516 (Sundai Chemicals, China) orally at 5 mg/kg for 4 days prior to, and 5 days after freeze burn injury to the TA muscle.

Up-regulation of known PPAR5 target genes (PDK4, CPTlb, and catalase) in the TA muscle was confirmed by QPCR, attesting to the successful delivery and activity of the PPAR5 ligand in the muscle (FIG. 5A). While vehicle treated animals showed Evans Blue dye uptake in 7.6% of the cross sectional area (CSA), only 4.9% of the muscle CSA was stained in the ligand treated animals (FIGS. 5B and 5C). Thus, PPAR5 ligand-treated animals showed a 34.7% reduction in damaged muscle fibers 5 days after the injury, demonstrating that pharmacological activation of PPAR5 enables accelerated restoration of myofiber integrity after injury.

Consistent with the PPAR5 ligand conveying a regenerative advantage, BrdU injection at 48 hours after the injury showed a marked increase in proliferative cell number in the ligand treated muscle, supporting the notion that PPAR5 activation promotes myoblast proliferation after injury (FIG. 5D). While the number of quiescent satellite cells was not significantly affected by either 9 days or 4 weeks of ligand treatment, satellite cells do not undergo rapid turnover. Thus, the duration of ligand treatment may have been insufficient to affect the numbers of these long-lived progenitor cells. Nonetheless, GW501516 treatment promoted myoblast proliferation in vivo after the injury, which may contribute to the accelerated regeneration after the injury.

The expression of inflammatory marker genes was measured after injury by QPCR. While the initial inflammatory responses at 12 hours after injury are similar with and without PPAR5 ligand treatment , a significant reduction in both TNFoc and the macrophage marker F4/80 expression was seen at 3 days post injury in PPAR5 ligand treated muscle (FIG. 5E). These results are consistent with the known role of PPAR5 as an anti-inflammatory regulator, and corroborate the beneficial findings observed in the VP16- PPAR5 genetic model.

EXAMPLE 7

Muscle specific activation of PPAR5 is protective against exercise-induced injury

WT and TG mice were acclimated to moderate treadmill running (10 m/min for 15 min) every other day for lweek. After acclimation, the speed was gradually increased to 15 m/min and then maintained constant until exhaustion (week 0). Subsequently, mice were subjected to 4weeks (5days/week) of exercise training on a treadmill inclined at 5 degree incline, with progressively increasing intensity and time. At the end of the training protocol (week 5), mice were run to exhaustions and serum samples were taken for the measurement of creatine kinase levels.

WT and VP16-PPAR5 (TG) mice were run to exhaustion, and their serum creatine kinase (CK) levels we measured by ELISA. The levels of CK in the TG mice were significantly lower than those in WT mice, indicative of reduced exercise -induced muscle damage (FIG. 6).

EXAMPLE 8

Muscle specific activation of PPAR5 enhances recovery after injury

This example describes adaptive responses bestowed by PPAR5 activation in the muscle which may contribute to the observed beneficial effects on regeneration.

Evans Blue staining of transverse sections of injured TA from WT and TG animals revealed decreased staining in TG muscle at 3 days post injury, consistent with PPAR5 activation being beneficial for muscle repair (FIG. 7A). Supporting this notion, endogenous PPAR5 is transiently increased in the TA muscle after freeze burn injury (FIG. 7B). Furthermore, the temporal expression profile of the inflammatory marker TNFoc in wildtype (WT, solid line) and VP16-PPAR5 (TG, dashed line) after injury was altered, suggesting a more rapid resolution of the inflammatory response in TG muscle (FIG. 7C). Increased vasculature is one of the hallmarks of oxidative myofibers, which facilitates introduction of immune cells and also supports increased number of satellite cells. TG animals show increased expression of VEGFa at both the mRNA and protein levels in TA muscle (FIG. 7D-E). EXAMPLE 9

Enhanced Notch signaling in VP16-PPAR5 muscle

Notch signaling is critical for skeletal muscle myogenesis and has important roles in maintaining the muscle stem cell pool and preventing premature muscle differentiation. To investigate whether constitutive PPAR5 activation affects the Notch signaling pathway, we compared the expression of selected genes in the pathway in TA muscle from WT and VP16-PPAR5 transgenic (TG) mice. Microarray analyses identified the upregulation of multiple genes in the Notch pathway in TG muscle (FIG. 8A). The PPAR5-induced increase in expression of Jagl, Jag2, Notch3 and Notch4 were confirmed in TA muscle from 2 month old mice by QPCR (FIG.8B). Consistent with the notion that PPAR5 activates the Notch pathway , increases in Notchl and Hesl expression were seen in mice after pharmacological activation via a 9 day treatment with the PPAR5 ligand, GW501516.(FIG. 8C). Furthermore, examination of 12 month old TG mice revealed increased expression of Jagl, Heyl, and Notch3, consistent with the sustained activation of the Notch pathway in VP16-PPAR5 mice (FIG. 8D). EXAMPLE 10

Pharmacokinetics of PPAR5 ligands

The oral bioavailability and serum half lives of PPAR5 ligands were compared in mice. The pharmacokinetics of PPAR5 ligands delivered orally (10 mg/kg p.o.) and intravenously (3 mg.kg i.v.) were determined by mass spectrometry. The circulating serum levels of novel PPAR5 ligands (FIGS. 9A, B, C, E) at indicated times after drug delivery, as compared with GW501516 (FIG. 9D).

In summary, PPAR5 activation expedites skeletal muscle regeneration following an acute thermal injury. VP16- PPAR5 transgenic animals showed increased satellite cell proliferation at the early phase of the regenerative process, which subsequently translated into increased CSA and number of nascent regenerating fibers. Most interestingly, muscle specific over expression of PPAR5 seems to increase the resident satellite cell pool. Increased satellite cell population on a muscle fiber seems to contribute to the accelerated resolution of the injury. These findings unveil a novel role for PPAR5 in the maintenance of skeletal muscle; as a potential therapeutic target for accelerated restoration of muscle mass after an acute injury and other atrophic conditions.

Notably, PPAR5 activation seems to promote rapid emergence of nascent fibers after the injury. There being no evidence of hyperplasia at 21 days after the injury when the regenerative process is essentially complete, it is concluded that the additional nascent fibers efficiently fuse with each other to restore mature fibers (Karpati G, Molnar MJ in Skeletal muscle repair and regeneration, eds Schiaffino S,

Partridge T (Springer, Dordrecht), (2008)). While IGF-1 and myostatin seem to rely on fiber hypertrophy to augment regenerative progress, PPAR5 seems to employ a unique way to promote regeneration (Menetrey et al , J Bone Joiny Surg Br 82(l): 131-7 (2000); Wagner et al , Ann Neurol 52(6): 832-6 (2002); Bogdanovich et al , Nature 420(6914):418-21 (2002)). Underlying this difference may be the increased number of quiescent satellite cells. Higher number of progenitor cells leads to the increase in post injury proliferating cells and consequent increase in the number of nascent fibers. While various growth factors and

chemokines, including IGF-1 and myostatin, have been shown to enhance proliferation of satellite cells and promote regeneration, it is unclear whether any of them positively regulate the number of quiescent satellite cells (Husmann I et al. , Cytokine Growth Factor Rev 7(3):249-258 (1996); McCroskery et al. , Cell Biol 162(6): 1135-1147 (2003); Musaro et al, Nat Genet 27: 195-200 (2001); Amthor et al, PNAS 106(18):7479- 84 (2009)). The findings shown herein indicate a novel role of PPAR5 as a positive regulator of satellite cell pool. Interestingly, since rapid cell proliferation was not observed under normal conditions, PPAR5 mediated satellite cell expansion is transient and tightly regulated, most likely elicited by external stimuli, such as signals for postnatal growth and injury. In an adult muscle, satellite cell number is finite, diminishing detrimentally in disease state and aging. It is of great therapeutic benefit if PPAR5 activation can bestow infinite abundance of satellite cell population throughout the life of an organism.

While enhancement in regenerative capacity was observed in both genetic and pharmacological models, the inherent differences in the experimental parameters is acknowledged. Orally administered

GW501516 was delivered systemically, presumably activating PPAR5 in a variety of organs and cell types in the animal. However, in VP16- PPAR5 animals, activation of the PPAR5 receptors is limited to the mature muscle fibers. Additionally, genetic background of the animals may affect the efficiency of regeneration after an injury (Grounds and McGeachie, Cell Tissue Res 255(2):385-391 (1989); Roberts et al., J Anat 191 :585-594 (1997)). Extramuscular effects of PPAR5 agonist administration may require further investigation when considering clinical use of GW501516 to augment muscle injury treatment. Recently, pharmacological activation of PPAR5 has been shown to improve sarcolemmal integrity in mdx mice (Miura et al , Hum Mol Genet 18(23):4640-4649 (2009)).

The results herein expand previous understandings of the role of PPAR5 in muscle physiology. It is shown herein that PPAR5 not only controls running endurance and metabolic parameters in the muscle, but also its regenerative program. PPAR5 activation affects multiple facets of the regenerative program, exerting comprehensive but transient effects to expedite the progress. In view of these findings, PPAR5 may be pharmacologically targeted to enhance the regenerative capacity of the muscle after injury and possibly other degenerative conditions where satellite cell function is compromised. For example, PPAR5 activation can be used to treat other degenerative conditions such as aging induced satellite cell dysfunction and ensuing sarcopenia. EXAMPLE 11

PPAR5 activity screen

Cell Culture and Transfection: CV-1 cells were grown in DMEM+10 charcoal stripped FCS. Cells were seeded into 384-well plates the day before transfection to give a confluency of 50-80% at transfection. A total of 0.8 g DNA containing 0.64 micrograms pCMX-PPARDelta LBD, 0.1 micrograms pCMX.beta.Gal, 0.08 micrograms pGLMH2004 reporter and 0.02 micrograms pCMX empty vector was transfected per well using FuGene transfection reagent according to the manufacturer's instructions (Roche). Cells were allowed to express protein for 48 h followed by addition of compound.

Plasmids: Human PPAR5 was used to PCR amplify the PPAR5 LBD. The amplified cDNA ligand binding domain (LBD) of PPAR5 isoform was (PPAR5 amino acid 128 to C-terminus) and fused to the

DNA binding domain (DBD) of the yeast transcription factor GAL4 by subcloning fragments in frame into the vector pCMX GAL (Sadowski et al. (1992), Gene 118, 137) generating the plasmids pCMX-PPARDelta LBD. Ensuing fusions were verified by sequencing. The pCMXMH2004 luciferase reporter contains multiple copies of the GAL4 DNA response element under a minimal eukaryotic promoter (Hollenberg and Evans, (1988) Multiple and cooperative trans-activation domains of the human glucocorticoid receptor Cell 55, 899). pCMX Gal was generated.

Compounds: All compounds were dissolved in DMSO and diluted 1: 1000 upon addition to the cells. Compounds were tested in quadruple in concentrations ranging from 0.001 to 100 μΜ. Cells were treated with compound for 24 h followed by luciferase assay. Each compound was tested in at least two separate experiments.

Luciferase assay: Medium including test compound was aspirated and washed with PBS. 50μ1 PBS including 1 mM Mg++ and Ca++ were then added to each well. The luciferase assay was performed using the LucLite kit according to the manufacturer's instructions (Packard Instruments). Light emission was quantified by counting on a Perkin Elmer Envision reader. To measure 3-galactosidase activity 25 μΐ supernatant from each transfection lysate was transferred to a new 384 niicroplate. Beta-galactosidase assays were performed in the microwell plates using a kit from Promega and read in a Perkin Elmer Envision reader. The beta-galactosidase data were used to normalize (transfection efficiency, cell growth etc.) the luciferase data.

Statistical Methods: The activity of a compound is calculated as fold induction compared to an untreated sample. For each compound the efficacy (maximal activity) is given as a relative activity compared to GW501516, a PPAR5 agonist. The EC5 ₀ is the concentration giving 50% of maximal observed activity. EC5 ₀ values were calculated via non-linear regression using GraphPad PRISM (GraphPad

Software, San Diego, Calif.).

Reactions were carried out in a Biotage Initiator 60 Microwave Reactor, employing the 20mL process-scale reactor vials. Thirteen (13) identical reactions at the 10 mmol scale were setup in parallel and processed in serial, as follows:

All three (3) reagents and reaction solvent were added to the MW vial in the following sequence; (1) ethyl-bromo-hexanoate (1.77 mL), (2) salicylaldehyde (1.05 mL), (3) cesium carbonate (CS ₂ CO ₃ ) (3.91 g) and (4) reaction solvent DMA (17.18 mL).

To each vial was added a magnetic stir bar and fitted with a crimp seal cap and adapter collar. The reactions were than process in the MW Reactor for 10 minutes (at temperature) at 120 °C with mixing. Following standard ramp up, fixed hold time at temperature and cool down, samples were kept sealed at ambient temperature until the entire lot was processed.

Reactions were carried out in a Biotage Initiator 60 Microwave Reactor, employing the 20 mL process-scale reactor vials. Eleven (11) identical reactions at the 4.09 mmol scale were setup in parallel and processed in serial, as follows:

All four (4) reagents and reaction co-solvents were added to the MW vial in the following sequence;

(1) Ethyl 6-(2-((4-bromo-N-cyclopropylbenzamido)methyl)phenoxy) hexanoate (about 2 g), (2) Furan-2- boronic acid (572 mg), (3) Pd(PPh ₃ ) ₄ (141.8 mg), (4) 2.0 M sodium carbonate solution (6.135 mL), followed by the co-solvents 95% EtOH and DME (1,2-dimethoxy ethane). Care was taken to dispense the DME solvent in such a manner so as to wash down the vial walls of solid catalyst. To each vial was added a magnetic stir bar and fitted with a crimp seal cap and adapter collar. The reactions were than process in the MW Reactor for 10 minutes (at temperature) at 140 °C with mixing. Following standard ramp up, fixed hold time at temperature and cool down, samples were kept sealed at ambient temperature until the entire lot was processed. Note, depending on the age of the tetrakis Pd catalyst (fresh when red, darkens to brown with age) the microwave reaction temperature may need to be increased and the reaction time lengthened. It has been observed that a trace side product increases with reaction temp/time and corresponds to the saponified ester, which is the next and final synthetic step. This ester hydrolysis should be expected given the excess base in the presence of water and ethanol as co-solvents. Therefore the ethyl ester is not isolate.

The crude reaction mixtures were individually opens and poured out onto a 800 mL sintered filtration funnel (medium porosity) fitted with a 2L side arm Erlenmeyer flask attached to house vacuum. The funnel was charged with a 2-3" bed of flash grade silica gel (Silicycle, 60A, 40-63 μιη, F60 silica gel). A second layer (about 1-2") of diatomaceous earth filter aid (Celite 545) was packed on top of the silica gel, to produce a binary dry column vacuum chromatography (DCVC) system. A typical CV was about 100 mL, and each reaction mixture was eluted with 1CV of chromatography grade THF. The column was washed with 4CV of THF until no reaction product(s) were visible by TLC. The THF mixture was concentrated to produce about 25 g of viscous oil isolated, that was then taken directly onto the next step. Theoretical yield = 11 x 1.95 g or 21.45 g (45.0 mmol). NMR (¾ ¹³ C, COSY) and LCMS (ESI+/-) conform to structure.

Reaction Step 5 - Saponification

Reactions were carried out in a Biotage Initiator 60 Microwave Reactor, employing the 20 mL process-scale reactor vials. Twenty-two (22) identical reactions at the 2.045 mmol scale were setup in parallel and processed in serial, as follows:

All two (2) reagents and reaction co-solvents were added to the MW vial in the following sequence; (1) crude ethyl 6-(2-((N-cyclopropyl-4-(furan-2-yl)benzamido) methyl)phenoxy) hexanoate was dissolved to a volume of 33 mL, 15 mL per reaction vial, and (2) LiOH (hydrate) as a 2 M solution in water, 5 mL per reaction vial. To each vial was added a magnetic stir bar and fitted with a crimp seal cap and adapter collar. The reactions were than process in the MW Reactor for 10 minutes (at temperature) at 150 °C with mixing. Following standard ramp up, fixed hold time at temperature and cool down, samples were kept sealed at ambient temperature until the entire lot was processed.

The crude reaction mixtures were individually opens and poured out onto a 800 mL sintered filtration funnel (medium porosity) fitted with a 2L side arm Erlenmeyer flask attached to house vacuum. The funnel was charged with a 2-3" bed of flash grade silica gel (Silicycle, 60A, 40-63 μιη, F60 silica gel). A second layer (about 1-2") of diatomaceous earth filter aid (Celite 545) was packed on top of the silica gel, to produce a binary dry column vacuum chromatography system. The dry column was acid washed (acidified with either 1M citric acid or IN HC1) with 2 x 1L of acid solution. A typical CV was about 100 mL, and each reaction mixture was eluted with 1 CV of 1 : 1 DCM-THF. The column was washed with 4 CV of 1 :1 DCM-THF until no reaction product(s) were visible by TLC. The DCM-THF mixture was concentrated to produce about 21 g of viscous oil. This crude product exhibited impurities with Rf values close to that of the desired material. Flash chromatography used four (4) Biotage 65i columns on Biotage SP4, loading about 5 g crude. Theoretical yield = 22 x 915.2 mg or 20.13 g (45.0 mmol). Isolation and Observed yield = 11.54 g, (11.54 g/20.13 g x 100) = 57.3%. NMR (¾ ¹³ C, COSY) and LCMS (ESI+/-) conform to structure.

Reaction Step 6 - Salt formation

6-(2-((N-cyclopropyl-4-(furan-2-yl)benzamido) methyl)phenoxy)hexanoic acid was dissolved in 75 mL of THF and cooled to 0 °C. NaOH (1.135 g) was dissolved in 25 mL water, and added dropwise to the stirring THF solution. After the addition was complete the reaction color was very dark (grayish-balck), the ice bath was removed and the reaction as allowed to warm to room temperature and continue to stir an additional 2 hours. The crude reaction mixture was then concentrated and the water was azeotroped away by charging the flask with about 100 mL portions of MeCN (20 times). The solution salt still was not crashing out or precipitating, so the crude salt was places on high vacuum overnight. A white crystalline solid appeared, and was triturated with fresh portions of MeCN, filtered and dried overnight once again to yield a 10.0 g portion (excluding additional material for secondary crystallization from the mother liquor).

Theoretical yield = 12.1 g (25.78 mmol). Observed yield = 10.0 g, (10.0 g/12.1 g ^χ 100) = 82.6%. NMR (¾ ¹³ C, COSY) and LCMS (ESI+/-) conform to structure.

The following examples provide physical and in vitro data for various different exemplary compounds.

Nuclear Hormone Receptor (NHR) Assays

Cell Handling: PathHunter NHR cell lines were expanded from freezer stocks according to standard procedures. Cells were seeded in a total volume of 20 \L into white walled, 384-well microplates and incubated at 37 °C for the appropriate time prior to testing. Assay media contained charcoal-dextran filtered serum to reduce the level of hormones present. Agonist Format: For agonist determination, cells were incubated with sample to induce response.

Intermediate dilution of sample stocks was performed to generate 5X sample in assay buffer. 5 μΐ _^ of 5X sample was added to cells and incubated at 37 °C or room temperature for 3-16 hours. Final assay vehicle concentration was 1%.

Antagonist Format: For antagonist determination, cells were pre-incubated with antagonist followed by agonist challenge at the ECso concentration. Intermediate dilution of sample stocks was performed to generate 5X sample in assay buffer. 5 μΐ _^ of 5X sample was added to cells and incubated at 37 °C or room temperature for 60 minutes. Vehicle concentration was 1%. 5 μΐ _^ of 6X ECso agonist in assay buffer was added to the cells and incubated at 37 °C or room temperature for 3-16 hours.

Signal Detection: Assay signal was generated through a single addition of 12.5 or 15 (50% v/v) of

PathHunter Detection reagent cocktail, followed by a one hour incubation at room temperature. Microplates were read following signal generation with a PerkinElmer EnvisionTM instrument for chemiluminescent signal detection.

Data Analysis: Compound activity was analyzed using CBIS data analysis suite (Chemlnnovation, CA). For agonist mode assays, percentage activity was calculated using the following formula:

% Activity =100% x (mean RLU of test sample— mean RLU of vehicle control) / (mean MAX control ligand— mean RLU of vehicle control).

For antagonist mode assays, percentage inhibition was calculated using the following formula:

% Inhibition =100% x (1— (mean RLU of test sample— mean RLU of vehicle control) / (mean RLU of ECeo control— mean RLU of vehicle control)).

Note that for select assays, the ligand response produces a decrease in receptor activity (inverse agonist with a constitutively active target). For those assays inverse agonist activity was calculated using the following formula:

% Inverse Agonist Activity =100% x ((mean RLU of vehicle control— mean RLU of test sample) / (mean RLU of vehicle control— mean RLU of MAX control)).

GW treatment prevents the accumulation of VLCFAs by inducing mitochondrial FA oxidation in a mouse model of ALD

As GW treatment dramatically induced mitochondrial fatty acid (FA) oxidation and reduced fat accumulation, GW was evaluated to see if could improve FA metabolism disorders such as ALD. ALD is a rare genetic disorder caused by defects in peroxisomal oxidation of very long-chain fatty acids (VLCFAs), resulting in systemic accumulation of VLCFAs, which causes tissue defects mainly in the central nervous system and the adrenal glands. The majority of VLCFAs in the body are endogenously synthesized from long-chain fatty acids (LCFAs). Therefore, one potential way to prevent VLCFA accumulation in ALD is by inducing mitochondrial LCFA oxidation to reduce the availability of LCFAs for VLCFA biosynthesis. In order to test this, a previously described mouse model of ALD was used, in which the X-linked

adrenoleukodystrophy gene abcdl was systemically ablated and the knockout (AKO) mice faithfully recapitulated the abnormal VLCFA accumulation phenotype seen in ALD patients. 3-month-old AKO mice were treated with or without GW and their tissues collected for free FA analysis using GC/MS. Similar to what was previously reported, both brain and liver from AKO mice had greatly increased levels of VLCFAs including C22:0, C23:0, C24:0, and C26:0, while the levels of total FAs (C12-C26) remained unaffected (FIGS. 10A and 10B). After 8 weeks of GW treatment, the levels of all four VLCFAs in AKO brain and liver were significantly reduced, with all liver C26:0 cleared in most GW- treated animals (FIGS. 10A and 10B). Without being bound to a particular theory, the reduction of VLCFAs may be due to GW-induced mitochondrial FA oxidation in peripheral tissues, since GW treatment dramatically induced the expression of mitochondrial FA oxidation genes including Cptla and lb, Slc25a20, and Acadl in AKO liver and skeletal muscle (FIGS. 11 A and 1 IB), which was further supported by the fact that most saturated LCFAs including C12:0 to C22:0 and the total FAs were significantly reduced by GW treatment in both liver and muscle (FIGS. 12A, 12B and 10B).
