The present disclosure relates to small molecule calpain modulatory compounds, pharmaceutical compositions comprising the compounds, and methods of using the compounds and compositions to modulate calpain activity, including methods to treat diseases and conditions mediated at least in part by the physiologic effects of CAPN1, CAPN2 or CAPN9, or combinations thereof.
Fibrotic disease accounts for an estimated 45% of deaths in the developed world but the development of therapies for such diseases is still in its infancy. The current treatments for fibrotic diseases, such as for idiopathic lung fibrosis, renal fibrosis, systemic sclerosis, and liver cirrhosis, are few in number and only alleviate some of the symptoms of fibrosis while failing to treat the underlying cause.
Despite the current limited understanding of the diverse etiologies responsible for these conditions, similarities in the phenotype of the affected organs, across fibrotic diseases, strongly support the existence of common pathogenic pathways. At present, it is recognized that a primary driver of fibrotic disease is a high transforming growth factor-beta (TGFβ) signaling pathway which can promote the transformation of normally functioning cells into fibrosis-promoting cells. Termed “myofibroblasts,” these transformed cells can secrete large amounts of extracellular matrix proteins and matrix degrading enzymes, resulting in the formation of scar tissue and eventual organ failure. This cellular process is transformative and termed “myofibroblast differentiation” (which includes Epithelial-to-Mesenchymal Transition (EpMT) and its variations like Endothelial-to-Mesenchymal Transition (EnMT) and Fibroblast-to-Myofibroblast Transition (FMT)). This process is a major target for the treatment of fibrotic diseases. Myofibroblast differentiation has also been shown to occur within cancer cells that have been chronically exposed to high TGFβ, causing stationary epithelial cells to become motile, invasive, and metastasize. Thus, within the context of cancer, the signaling has been documented to associate with the acquisition of drug resistance, immune system evasion, and development of stem cell properties.
Despite the tremendous potential of myofibroblast differentiation-inhibiting drugs, and the numerous attempts to develop a working treatment, the data gathered thus far has yet to translate into practical therapy. This is partly due to the lack of an ideal target protein. Initial strategies to target the myofibroblast differentiation process focused on proximal inhibition of the TGFβ signaling pathway by various methods, including targeting ligand activators (e.g., alpha-v integrins), ligand-receptor interactions (e.g., using neutralizing antibodies) or TGFβ receptor kinase activity (e.g., small molecule chemical compound drugs to block signal transduction). Unfortunately, TGFβ is a pleiotropic cytokine with many physiological functions such that global suppression of TGFβ signaling was also associated with severe side effects. Additionally, current data suggests that such proximal inhibition may be vulnerable to pathologic workaround strategies (i.e., due to redundancy or compensation), that would limit the utility of such drugs. Further complicating matters is that, in cancer, TGFβ signaling early on functions as an anti-tumorigenic growth inhibitor but later becomes tumor promoting and is another reason why selective inhibition of pathogenic elements of signaling is so strongly desired. In light of these inherent limitations, current treatment strategies have refocused on identification and inhibition of critical distal events in TGFβ signaling, which in theory would preferentially target the pathologic, but not physiological functions of TGFβ signaling.

As used herein and in the appended claims, singular articles such as “a,” “an” and “the” and similar referents in the context of describing the elements (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, including the upper and lower bounds of the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the embodiments and does not pose a limitation on the scope of the claims unless otherwise stated. No language in the specification should be construed as indicating any non-claimed element as essential.
Generally, reference to a certain element such as hydrogen or H is meant to include all isotopes of that element. For example, if an R group is defined to include hydrogen or H, it also includes deuterium and tritium. Compounds comprising radioisotopes such as tritium, C14, P32 and S35 are thus within the scope of the present technology. Procedures for inserting such labels into the compounds of the present technology will be readily apparent to those skilled in the art based on the disclosure herein.
As used herein, “a fibrotic disease” includes, for example, liver fibrosis (alcoholic, viral, autoimmune, metabolic and hereditary chronic disease), renal fibrosis (e.g., resulting from chronic inflammation, infections or type II diabetes), lung fibrosis (idiopathic or resulting from environmental insults including toxic particles, sarcoidosis, asbestosis, hypersensitivity pneumonitis, bacterial infections including tuberculosis, medicines, etc.), interstitial fibrosis, systemic scleroderma (autoimmune disease in which many organs become fibrotic), macular degeneration (fibrotic disease of the eye), pancreatic fibrosis (resulting from, for example, alcohol abuse and chronic inflammatory disease of the pancreas), fibrosis of the spleen (from sickle cell anemia, other blood disorders) cardiac fibrosis (resulting from infection, inflammation and hypertrophy), mediastinal fibrosis, myelofibrosis, endomyocardial fibrosis, retroperitoneal fibrosis, progressive massive fibrosis, nephrogenic systemic fibrosis, fibrotic complications of surgery, especially surgical implants, injection fibrosis and secondary conditions and disease states of fibrosis.

The term “sufficient amount” means an amount sufficient to produce a desired effect, e.g., an amount sufficient to modulate protein aggregation in a cell.
The term “therapeutically effective amount” is an amount that is effective to ameliorate a symptom of a disease. A therapeutically effective amount can, in some embodiments, be a “prophylactically effective amount” as prophylaxis can be considered therapy.
Stereoisomers of compounds (also known as optical isomers) include all chiral, diastereomeric, and racemic forms of a structure, unless the specific stereochemistry is expressly indicated. Thus, compounds used in the present technology include enriched or resolved optical isomers at any or all asymmetric atoms as are apparent from the depictions. Both racemic and diastereomeric mixtures, as well as the individual optical isomers can be isolated or synthesized so as to be substantially free of their enantiomeric or diastereomeric partners, and these stereoisomers are all within the scope of the present technology.
The compounds of the present technology can exist as solvates, especially hydrates. Hydrates may form during manufacture of the compounds or compositions comprising the compounds, or hydrates may form over time due to the hygroscopic nature of the compounds. Compounds of the present technology can exist as organic solvates as well, including DMF, ether, and alcohol solvates among others. The identification and preparation of any particular solvate is within the skill of the ordinary artisan of synthetic organic or medicinal chemistry.
“Subject” refers to a mammalian organism treated using a compound of the present invention. The “subject” can be a human or non-human mammalian organism.
“Tautomer” refer to alternate forms of a compound that differ in the position of a proton, such as enol-keto and imine-enamine tautomers, or the tautomeric forms of heteroaryl groups containing a ring atom attached to both a ring NH moiety and a ring ═N moiety such as pyrazoles, imidazoles, benzimidazoles, triazoles, and tetrazoles.
“Treating” or “treatment” of a disease or disorder in a subject refers to 1) preventing the disease or disorder from occurring in a subject that is predisposed or does not yet display symptoms of the disease or disorder; 2) inhibiting the disease or disorder or arresting its development; or 3) ameliorating or alleviating the cause of the regression of the disease or disorder.
Unless indicated otherwise, the nomenclature of substituents that are not explicitly defined herein are arrived at by naming the terminal portion of the functionality followed by the adjacent functionality toward the point of attachment. For example, the substituent “alkoxycarbonylalkyl” refers to the group (alkoxy)-C(O)-(alkyl)-.
As used herein, the following definitions shall apply unless otherwise indicated. Further, if any term or symbol used herein is not defined as set forth below, it shall have its ordinary meaning in the art.

Schultz, “Beyond the Canonical 20 Amino Acids: Expanding the Genetic Lexicon,” J. Biol. Chem. 2010 285: 11039-11044.
As used herein, the phrase “modulating or inhibiting (the activity of) CAPN1, CAPN2, and/or CAPN9” refers to use of any agent capable of altering the cellular expression levels and/or biological activity of the CAPN1, CAPN2, and/or CAPN9 gene, messenger RNA, or protein. In some embodiments, an agent that modulates or inhibits the biological activity of CAPN1, CAPN2, and/or CAPN9 directly interferes with the expression (such as transcription, splicing, transport, etc.) of the gene encoding the CAPN1, CAPN2, and/or CAPN9 mRNA. In other embodiments, an agent that modulates or inhibits the activity of CAPN1, CAPN2, and/or CAPN9 directly interferes with the biological activity or production of the CAPN1, CAPN2, and/or CAPN9 proteins (such as though inhibition of translation, post-translational modifications, intracellular transport, disruption of interactions between one or more proteins, etc.). In yet other embodiments, an agent that modulates or inhibits the activity of CAPN1, CAPN2, and/or CAPN9 does not directly affect the expression level or activity of CAPN1, CAPN2, and/or CAPN9 but, instead, alters the activity or expression levels of a protein whose function directly impacts the expression or activity of CAPN1, CAPN2, and/or CAPN9 (such as, for example, calpastatin). In other embodiments, an agent may specifically inhibit one or more CAPN1, CAPN2, and/or CAPN9 enzymes. In yet other embodiments, an agent may selectively inhibit CAPN1, CAPN2, and/or CAPN9 enzymes. In yet other embodiments, an agent may both specifically and selectively inhibit one or more CAPN1, CAPN2, and/or CAPN9 enzymes. In yet other embodiments, an agent is neither a specific nor selective inhibitor for one or more CAPN1, CAPN2, and/or CAPN9 enzymes, but is still active for the inhibition of one or more of the CAPN1, CAPN2, and/or CAPN9 enzymes. Calpains are also expressed in cells other than neurons, microglia and invading macrophages. In particular, they are important in skeletal muscle and herein inhibition of calpains also refers to inhibition in these cells as well.
As used herein, an agent is said to be “specific” if it reacts or associates more frequently, more rapidly, with greater duration and/or with greater affinity with a particular target (for example, a protein, such as CAPN9, CAPN2, or CAPN1 as well as a nucleic acid encoding the same) than it does with alternative substances, especially as compared to substances that are structurally related to the target, e.g., an isoform of the target. For instance, an antibody “specifically binds” to a target protein (such as CAPN9, CAPN2, or CAPN1 if it binds with greater affinity, avidity, more readily, and/or with greater duration than it binds to other substances.
In some embodiments, an agent is “specific” for a target if a concentration of the agent that produces a maximal effect in an in vitro or in vivo target assay (e.g., a binding assay or an enzyme activity assay) produces no measurable effect in a comparable assay carried out using another substance, especially one or more substances that are structurally related to the target.
As used herein, an agent is said to be a “specific inhibitor” of CAPN1, CAPN2 or CAPN9 if it inhibits the biological activity and/or expression level of CAPN1, CAPN2 or CAPN9 without inhibiting the biological activity and/or expression level of other members of the calpain family of proteases or other members of the TRP family of calcium channels.
As used herein, an agent is an agent is said to be “selective” if it reacts or associates more frequently, more rapidly, with greater duration and/or with greater affinity with a particular target or a small set of structurally-related targets (for example, a protein, such as CAPN9, CAPN2, or CAPN1 as well as a nucleic acid encoding the same) than it does with alternative substances, especially as compared to other substances that are structurally related to the target or small set of structurally-related targets, e.g., an isoform of the target. In certain embodiments, a “selective” agent reacts similarly with multiple related targets, whereas a “specific” agent reacts with its target in a manner that is markedly differently from the way it interacts with other biological molecules. For instance, an antibody “selectively binds” to a target protein (such as CAPN9, CAPN2, or CAPN1 if it binds with greater affinity, avidity, more readily, and/or with greater duration to two related targets (e.g., CAPN9, CAPN2) than it binds to other substances.
In some embodiments, an agent is “selective” for a set of targets if a concentration of the agent that produces a maximal effect in an in vitro or in vivo assay (e.g., a binding assay or an enzyme activity assay) with a first target molecule produces a measurable effect in a comparable assay carried out using a second target molecule. In some embodiments, an agent is selective if it binds to two or more targets (especially structurally-related targets) with Kd or IC50 (or other related measures) ratios of first to second target that are within a range of 1:1 to about 1:500.
As used herein, in some embodiments, an agent is said to be a “selective inhibitor” of CAPN1, CAPN2 or CAPN9 if it can be shown to inhibit the biological activity and/or expression level of two or three of CAPN1, CAPN2 or CAPN9 (e.g., CAPN1 and CAPN2, or CAPN1 and CAPN9, or CAPN2 and CAPN9 or CAPN1, CAPN2 and CAPN9) without inhibiting the biological activity and/or expression level of level of other members of the calpain family of proteases or other members of the TRP family of calcium channels.
As used herein, the term “contacting,” as used herein, includes both directly contacting cells, for example, in vivo, in vitro, or ex vivo, or indirectly contacting cells, such as, for example, by administering an agent to a subject. Further, “contacting” a cell with an agent includes administering or applying a prodrug version of the agent. In some embodiments, the cell is in a fibrotic tissue, a cancerous tissue, and/or tissue with high TGFβ signaling.
As used herein, the term “fibrosis” refers to the increased extracellular matrix protein synthesis and deposition that results in the accumulation of scar tissue. Similarly, as used herein, the term “fibrotic tissue” refers to tissue that has high levels of extracellular matrix proteins (i.e., collagen), undergone extensive remodeling (though activity of matrix metalloproteinases) and exhibits progressively diminished physiological function, due to the activity of cells that have undergone myofibroblast differentiation (such as, EMT and/or FMT). In some embodiments, the cell is in a cancerous tissue, such as in tissue that comprises at least one cancer cell. In some embodiments, the cell is in a tissue with high TGFβ signaling.
As used herein, the term “inhibit,” “decrease” and grammatical derivations thereof, refers to the ability of an agent to block, partially block, interfere, reduce or deactivate a pathway or mechanism of action. Thus, one of ordinary skill in the art would appreciate that the term “inhibit” or “decrease” encompasses a complete and/or partial loss of activity, e.g., a loss in activity by at least 10%, in some embodiments, a loss in activity by at least 20%, 30%, 50%, 75%, 95%, 98%, and up to and including 100%.
As used herein, the term “expression level and/or activity of a calpain” refers to the amount of a calpain found in a cell, tissue and/or subject, and/or a function of a calpain. Such functions can include, without limitation, its protease ability, its function in modulating TGFβ signaling, its function in myofibroblast transition (such as EMT and/or FMT). In some embodiments, the expression level of a calpain refers to mRNA expression level. In other embodiments, the expression level of a calpain refers to protein expression level. In some embodiments, the myofibroblast transition is EMT (such as a TGFβ-mediated EMT). In some embodiments, at least one agent inhibits Fibroblast-to-Myofibroblast Transition (FMT). In some embodiments, the calpain is CAPN9, CAPN1, and/or CAPN2.
As used herein, the terms “prevent,” “preventing,” “prevention,” “prophylactic treatment” and the like refer to reducing the probability of developing a disease, disorder, or condition in a subject, who does not have, but is at risk of or susceptible to developing a disease, disorder, or condition. Thus, in some embodiments, an agent can be administered prophylactically to prevent the onset of a disease, disorder, or condition, or to prevent the recurrence of a disease, disorder, or condition.
For the purposes of this specification and appended claims, unless otherwise indicated, all numbers expressing amounts, sizes, dimensions, proportions, shapes, formulations, parameters, percentages, parameters, quantities, characteristics, and other numerical values used in the specification and claims, are to be understood as being modified in all instances by the term “about” even though the term “about” may not expressly appear with the value, amount or range. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are not and need not be exact, but may be approximate and/or larger or smaller as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art depending on the desired properties sought to be obtained by the presently disclosed subject matter. For example, the term “about,” when referring to a value can be meant to encompass variations of, in some aspects, ±100% in some aspects ±50%, in some aspects ±20%, in some aspects ±10%, in some aspects ±5%, in some aspects ±1%, in some aspects ±0.5%, and in some aspects ±0.1% from the specified amount, as such variations are appropriate to perform the disclosed methods or employ the disclosed compositions.
Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by a person skilled in the art to which this invention belongs.

In some embodiments, the total dosage for a 70 kg adult is in the range of 0.001 to about 15 mg per kg weight of subject per administration or 0.01 to about 1.5 mg per kg weight of subject per administration, and such therapy can extend for a number of days, a number of weeks or months, and in some cases, years. It will be understood, however, that the specific dose level for any particular subject will depend on a variety of factors including the activity of the specific compound employed; the age, body weight, general health, sex and diet of the individual being treated; the time and route of administration; the rate of excretion; other drugs that have previously been administered; and the severity of the particular disease undergoing therapy, as is well understood by those of skill in the area.
General Synthetic Methods
The compounds of the present technology can be prepared from readily available starting materials using the following general methods and procedures. It will be appreciated that where typical or preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions can also be used unless otherwise stated. Optimum reaction conditions may vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures.
Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. Suitable protecting groups for various functional groups as well as suitable conditions for protecting and deprotecting particular functional groups are well known in the art. For example, numerous protecting groups are described in T. W. Greene and P. G. M. Wuts, Protecting Groups in Organic Synthesis, Third Edition, Wiley, New York, 1999, and references cited therein.
If the compounds of the present technology contain one or more chiral centers, such compounds can be prepared or isolated as pure stereoisomers, i.e., as individual enantiomers or d(l) stereoisomers, or as stereoisomer-enriched mixtures. All such stereoisomers (and enriched mixtures) are included within the scope of the present technology, unless otherwise indicated. Pure stereoisomers (or enriched mixtures) may be prepared using, for example, optically active starting materials or stereoselective reagents well-known in the art. Alternatively, racemic mixtures of such compounds can be separated using, for example, chiral column chromatography, chiral resolving agents and the like.
The starting materials for the following reactions are generally known compounds or can be prepared by known procedures or obvious modifications thereof. For example, many of the starting materials are available from commercial suppliers such as Aldrich Chemical Co. (Milwaukee, Wis., USA), Bachem (Torrance, Calif., USA), Emka-Chemce or Sigma (St. Louis, Mo., USA). Others may be prepared by procedures, or obvious modifications thereof, described in standard reference texts such as Fieser and Fieser's Reagents for Organic Synthesis, Volumes 1-15 (John Wiley, and Sons, 1991), Rodd's Chemistry of Carbon Compounds, Volumes 1-5, and Supplementals (Elsevier Science Publishers, 1989), Organic Reactions, Volumes 1-40 (John Wiley, and Sons, 1991), March's Advanced Organic Chemistry, (John Wiley, and Sons, 5th Edition, 2001), and Larock's Comprehensive Organic Transformations (VCH Publishers Inc., 1989).
Synthesis Routes to Compounds of the Present Technology
In one general embodiment, the method involves reacting an appropriately N-protected amino acid compound with an amino-protected side-chain, as starting material, with an N,O-dimethylhydroxylamine as a coupling partner and HATU to give the Weinreb amide. It is appreciated that other suitable coupling conditions and reagents, such as HOBt and/or DMAP, may be used to form a requisite Weinreb amide. The Wenireb amide is then reduced upon treatment with DIBAL or even LAH to the corresponding aldehyde. The skilled artisan will appreciate that there are many synthetic conditions or methods by which an ester functional group can be reduced to an aldehyde and such synthetic methods are well within in the scope of the present technology disclosed. The aldehyde then undergoes a cyanohydrin reaction upon treatment with KCN, which is then hydrolyzed under acidic conditions in alcohol to the corresponding α-hydroxy ester. If the side chain nitrogen has not already been de-protected, then the next step is to de-protect and make the free amine and cyclize it with the ester to form the cyclic amide. Finally, the α-hydroxyl group is oxidized under conditions for Dess-Martin Periodinane oxidation (with hypervalent iodine) or by an oxidizing agent such as PCC (pyridinium chlorochromate). The skilled artisan will once again appreciate that there are many other oxidizing conditions and agents which are within the scope of this disclosure to oxidize the hydroxyl group. At this point, the protecting group on the nitrogen atom is de-protected (and/or another group is connected to the nitrogen atom, for example an alkyl group thru a substitution or reductive amination reaction) and then the cyclic amine is coupled to the carboxylic acid group of another appropriately N-protected amino acid to form the desired compound. Of course it is recognized that at any point during this synthesis, the keto compounds may be interchanged with thio-keto compounds as treatment with Lawesson's reagent will give the corresponding thio-carbonyl compound. This synthesis route is generally shown in Scheme 1.
In one example, the compounds of general Formula I-XXXII can be generally prepared according to representative Scheme 1:
As an alternative, the skilled artisan will appreciate that these keto-amide compounds can also be prepared by converting the carboxylic acid functionality of the starting material, N-terminal protected amino acid (the side-chain may be protected as well), into an amide. In this way, the N—C bond connection to the cyclic keto-amide can be affected, optionally stereoselectively, by using the free nitrogen atom of the amide (on the C-terminus) to displace the appropriate and reactive functional group on the ring. Such functional group conversions are well known in the art and allow for complex substitution at the ring juncture. Typical substrates for displacement with the amide nitrogen are usually electrophilic in nature (though they need not be) and may include, but are not limited to: aldehydes, halides, alkenes, esters, carboxylic acids, ketones, and acid halides. Of course, either way the cyclization is affected, the skilled artisan will recognize that the requisite functional groups may be selected so that heteroatoms and multiple substituents can exist at any position of the ring. An ex
In one example, the compounds of general Formula I-XXXII can also be generally prepared according to representative Scheme 2:
Herein it is understood that amino, keto, thio, hydroxyl, and any other necessary protecting groups and their methods of deprotection are known in the art, such as those described in T. W. Greene and P. G. M. Wuts, Protecting Groups in Organic Synthesis, Third Edition, Wiley, New York, 1999.
Alternatively, the skilled artisan will recognize that there is additional synthetic functional group modifications that can use to prepare spirocyclic and other bicyclic compounds onto the cyclic keto-amide ring.
In one example, the compounds of general Formula I-XXXII can also be generally prepared according to representative Scheme 3:
Yet in another alternative aspect, the skilled artisan will recognize that other bicyclic systems can be prepared thru similar functional group transformations with groups on the amino acid side chain or on the nitrogen atoms outside the keto-amide ring.
In one example, the compounds of general Formula I-XXXII can also be generally prepared according to representative Scheme 4:
Administration and Pharmaceutical Composition
The present technology provides novel compounds possessing CAPN1, CAPN2, and/or CAPN9 inhibitory activity and, accordingly, are useful in treating conditions and/or disorders affected by (or at least in part by) CAPN1, CAPN2, and/or CAPN9. Such conditions include fibrosis and/or complications thereof.
Methods for treatment of fibrotic diseases are also encompassed by the present invention. Said methods of the invention include administering a therapeutically effective amount of any one of compounds of Formula I-XXXII. The compounds and solvates of the invention can be formulated in pharmaceutical compositions. These compositions can comprise a pharmaceutically acceptable excipient, carrier, buffer, stabilizer or other materials well known to those skilled in the art. The precise nature of the carrier or other material can depend on the route of administration, e.g. oral, intravenous, cutaneous or subcutaneous, nasal, intramuscular, intraperitoneal routes.
Pharmaceutical compositions for oral administration can be in tablet, capsule, powder or liquid form. A tablet can include a solid carrier such as gelatin or an adjuvant. Liquid pharmaceutical compositions generally include a liquid carrier such as water, petroleum, animal or vegetable oils, mineral oil or synthetic oil. Physiological saline solution, dextrose or other saccharide solution or glycols such as ethylene glycol, propylene glycol or polyethylene glycol can be included.
For intravenous, cutaneous or subcutaneous injection, or injection at the site of affliction, the active ingredient will be in the form of a parenterally acceptable aqueous solution which is pyrogen-free and has suitable pH, isotonicity and stability. Those of relevant skill in the art are well able to prepare suitable solutions using, for example, isotonic vehicles such as Sodium Chloride Injection, Ringer's Injection, Lactated Ringer's Injection. Preservatives, stabilizers, buffers, antioxidants and/or other additives can be included, as required.
A composition can be administered alone or in combination with other treatments, either simultaneously or sequentially dependent upon the condition to be treated.
In general, the compounds of the present technology will be administered in a therapeutically effective amount by any of the accepted modes of administration for agents that serve similar utilities. The actual amount of the compound of the present technology, i.e., the active ingredient, will depend upon numerous factors such as the severity of the disease to be treated, the age and relative health of the subject, the potency of the compound used, the route and form of administration, and other factors well known to the skilled artisan. The drug can be administered at least once a day, preferably once or twice a day.
An effective amount of such agents can readily be determined by routine experimentation, as can the most effective and convenient route of administration and the most appropriate formulation. Various formulations and drug delivery systems are available in the art. See, e.g., Gennaro, A. R., ed. (1995) Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Co.
A therapeutically effective dose can be estimated initially using a variety of techniques well-known in the art. Initial doses used in animal studies may be based on effective concentrations established in cell culture assays. Dosage ranges appropriate for human subjects can be determined, for example, using data obtained from animal studies and cell culture assays.
An effective amount or a therapeutically effective amount or dose of an agent, e.g., a compound of the present technology, refers to that amount of the agent or compound that results in amelioration of symptoms or a prolongation of survival in a subject. Toxicity and therapeutic efficacy of such molecules can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., by determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio of toxic to therapeutic effects is therapeutic index, which can be expressed as the ratio LD50/ED50. Agents that exhibit high therapeutic indices are preferred.
The effective amount or therapeutically effective amount is the amount of the compound or pharmaceutical composition that will elicit the biological or medical response of a tissue, system, animal or human that is being sought by the researcher, veterinarian, medical doctor or other clinician. Dosages particularly fall within a range of circulating concentrations that includes the ED50 with little or no toxicity. Dosages may vary within this range depending upon the dosage form employed and/or the route of administration utilized. The exact formulation, route of administration, dosage, and dosage interval should be chosen according to methods known in the art, in view of the specifics of a subject's condition.
Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety that are sufficient to achieve the desired effects; i.e., the minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from, for example, in vitro data and animal experiments. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.
The amount of agent or composition administered may be dependent on a variety of factors, including the sex, age, and weight of the subject being treated, the severity of the affliction, the manner of administration, and the judgment of the prescribing physician.
The present technology is not limited to any particular composition or pharmaceutical carrier, as such may vary. In general, compounds of the present technology will be administered as pharmaceutical compositions by any one of the following routes: oral, systemic (e.g., transdermal, intranasal or by suppository), or parenteral (e.g., intramuscular, intravenous or subcutaneous) administration. The preferred manner of administration is oral using a convenient daily dosage regimen that can be adjusted according to the degree of affliction. Compositions can take the form of tablets, pills, capsules, semisolids, powders, sustained release formulations, solutions, suspensions, elixirs, aerosols, or any other appropriate compositions. Another preferred manner for administering compounds of the present technology is inhalation.
The choice of formulation depends on various factors such as the mode of drug administration and bioavailability of the drug substance. For delivery via inhalation the compound can be formulated as liquid solution, suspensions, aerosol propellants or dry powder and loaded into a suitable dispenser for administration. There are several types of pharmaceutical inhalation devices-nebulizer inhalers, metered dose inhalers (MDI) and dry powder inhalers (DPI). Nebulizer devices produce a stream of high velocity air that causes therapeutic agents (which are formulated in a liquid form) to spray as a mist that is carried into the subject's respiratory tract. MDI's typically are formulation packaged with a compressed gas. Upon actuation, the device discharges a measured amount of therapeutic agent by compressed gas, thus affording a reliable method of administering a set amount of agent. DPI dispenses therapeutic agents in the form of a free flowing powder that can be dispersed in the subject's inspiratory air-stream during breathing by the device. In order to achieve a free flowing powder, therapeutic agent is formulated with an excipient such as lactose. A measured amount of therapeutic agent is stored in a capsule form and is dispensed with each actuation.
Pharmaceutical dosage forms of a compound of the present technology may be manufactured by any of the methods well-known in the art, such as, for example, by conventional mixing, sieving, dissolving, melting, granulating, dragee-making, tabletting, suspending, extruding, spray-drying, levigating, emulsifying, (nano/micro-) encapsulating, entrapping, or lyophilization processes. As noted above, the compositions of the present technology can include one or more physiologically acceptable inactive ingredients that facilitate processing of active molecules into preparations for pharmaceutical use.
Recently, pharmaceutical formulations have been developed especially for drugs that show poor bioavailability based upon the principle that bioavailability can be increased by increasing the surface area i.e., decreasing particle size. For example, U.S. Pat. No. 4,107,288 describes a pharmaceutical formulation having particles in the size range from 10 to 1,000 nm in which the active material is supported on a crosslinked matrix of macromolecules. U.S. Pat. No. 5,145,684 describes the production of a pharmaceutical formulation in which the drug substance is pulverized to nanoparticles (average particle size of 400 nm) in the presence of a surface modifier and then dispersed in a liquid medium to give a pharmaceutical formulation that exhibits remarkably high bioavailability.
The compositions are comprised of in general, a compound of the present technology in combination with at least one pharmaceutically acceptable excipient. Acceptable excipients are non-toxic, aid administration, and do not adversely affect therapeutic benefit of the claimed compounds. Such excipient may be any solid, liquid, semisolid or, in the case of an aerosol composition, gaseous excipient that is generally available to one of skill in the art.
Solid pharmaceutical excipients include starch, cellulose, talc, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, magnesium stearate, sodium stearate, glycerol monostearate, sodium chloride, dried skim milk and the like. Liquid and semisolid excipients may be selected from glycerol, propylene glycol, water, ethanol and various oils, including those of petroleum, animal, vegetable or synthetic origin, e.g., peanut oil, soybean oil, mineral oil, sesame oil, etc. Preferred liquid carriers, particularly for injectable solutions, include water, saline, aqueous dextrose, and glycols.
Compressed gases may be used to disperse a compound of the present technology in aerosol form. Inert gases suitable for this purpose are nitrogen, carbon dioxide, etc. Other suitable pharmaceutical excipients and their formulations are described in Remington's Pharmaceutical Sciences, edited by E. W. Martin (Mack Publishing Company, 18th ed., 1990).
The present compositions may, if desired, be presented in a pack or dispenser device containing one or more unit dosage forms containing the active ingredient. Such a pack or device may, for example, comprise metal or plastic foil, such as a blister pack, or glass, and rubber stoppers such as in vials. The pack or dispenser device may be accompanied by instructions for administration.

LC-MS: m/e 411 (M+H).
Both compound Int-3 (10 mg, 0.024 umol) and NHS (3 mg, 0.026 umol) were taken up in THF (1 mL) and cooled to 0° C. A THF (1 mL) solution of DCC (6 mg, 0.031 umol) was added dropwise. The solution was stirred at 0° C. for 0.5 hours before warming to 25° C. with stirring for an additional 2 hours. LC-MS indicated the disappearance of Int-3 and the formation of Int-4. The reaction solution was concentrated to afford Int-4 as a white waxy solid. The crude ester Int-4 was used directly in the next step without any further purification. LC-MS: m/e 508 (M+H).
Compound Int-4 (12 mg, 0.024 umol) was taken up in a 4M HCl/dioxane (1 mL) solution at 25° C. and stirring continued for 1 hour. LC-MS indicated the disappearance of Int-4 and the formation of Int-5. The reaction solution was concentrated to afford 5 as light yellow oil. The crude amine Int-5 was used directly in the next step without any further purification. LC-MS: m/e 408 (M+H).
Compound Int-5 (10 mg, 0.024 umol) was taken up in dioxane (1 mL) at 25° C. Addition of Et3N (12 mg, 0.12 umol, 17 ul) was followed by stirring at 100° C. for 1 hour. LC-MS indicated the disappearance of Int-5 and the formation of Int-6. The reaction solution was concentrated to afford crude Int-6 as a brown solid. LC-MS: m/e 293 (M+H).
Biochemical inhibition of Calpains 1, 2, and 9.
Calpains 1, 2, and 9 activity and inhibition thereof are assessed by means of a continuous fluorescence assay. The SensoLyte 520 Calpain substrate (Anaspec Inc) is optimized for detecting calpain activity. This substrate contains a novel internally quenched 5-FAM/QXLTM 520 FRET pair. Calpains 1, 2 and 9 cleave the FRET substrate into two separate fragments resulting in an increase of 5-FAM fluorescence that is proportional to calpain activity.
Assays are typically setup in black 384-well plates using automated liquid handling as follows. Calpain assay base buffer typically contains 50 mM Tris, pH 7.5, 100 mM NaCl and 1 mM DTT. Inhibitors are serially diluted in DMSO and used to setup 2× mixtures with calpains in the aforementioned buffer. After incubation at ambient temperature (25 C), the reaction is initiated by adding a 2× mix of the fluorescent peptide substrate and CaCl2 (required for in-situ calpain activation) in the same buffer. Reaction progress curve data are typically collected for 10 min using excitation/emission wavelengths of 490 nm/520 nm on SpectraMax i3x or the FLIPR-Tetra plate readers (Molecular Devices Inc). Reaction rates were calculated from progress curve slopes typically over 1-5 min. Dose response curves (rate vs. log inhibitor concentration) were typically fit to a 4-parameter logistic function to extract IC50 values.
Inhibition of Cellular Calpain Activity
Calpain activity in SH-SYSY cells and inhibition thereof are assessed by means of the Calpain-Glo™ platform (Promega, Inc) which is a homogeneous, luminescence assay that uses the cell-permeable and pro-luminescent calpain substrate Suc-LLVY-amino-luciferin. Upon calpain cleavage followed by cell lysis and quenching the luminescence signal developed is proportional to intra-cellular calpain activity.
Assays are typically setup by seeding SH-SYSY cells in white 384-well plates at 40 k/per well in RPMI-1640 containing 1% serum followed by 37 C overnight incubation. Next morning, cells are pre-incubated for 1 hr with serially diluted compounds followed by addition of 20 uM each of Suc-LLVY-aminoluciferin substrate and A23187 (ionophore used to induce Ca flux and calpain activity) diluted in Calpain-Glo buffer. After a 4 hr incubation at 37 C (calpain reaction), cells are lysed at 37 C for 1 hr using 0.9% Triton X-100 containing PBS with 100 uM MDL-28170 (excess calpain inhibitor to quench calpain activity). After centrifugation at 300 rpm, the Calpain-Glo™ luciferase detection reagent in Calpain-Glo™ buffer is added followed by 10 min incubation prior to reading luminescence counts using an EnVision plate reader (Perkin Elmer Inc). Dose response curves (luminescence vs. log inhibitor concentration) were typically fit to a 4-parameter logistic function to extract IC50 values.

Bleomycin-Induced Pulmonary Fibrosis in Mice or Rats
The method for inducing pulmonary fibrosis in mice is described in Current Protocols in Pharmacology: 5.46.1, entitled “Mouse Models of Bleomycin-induced Pulmonary Fibrosis”. In order to induce pulmonary fibrosis, 6-8 week old C57Bl/6 mice or Wistar rats are instilled once oropharyngeally with ˜1.5 U/kg of bleomycin sulfate (Calbiochem, Billerica, Mass.). Briefly, for oropharyngeal administration of bleomycin, mice or rats are anesthetized with isofluorane and then suspended on its back at a ˜60 degree angle on an inclined surface with a rubber band running under the upper incisors. The airway is opened while securing the tongue with one arm of padded forceps and bleomycin is administered into the back of the oral cavity with a syringe. The study is terminated on day 14-28 for oropharyngeally administered bleomycin in mice and rats.
Alternatively, for systemic bleomycin administration by osmotic pumps in mice, the pumps are loaded with bleomycin and implanted subcutaneously under isofluorane anesthesia as described in Lee, Am J Physiol Lung Cell Mol Physiol, 2014. Briefly, mice are systemically administered ˜50 U/kg bleomycin (Blenoxane; Teva Pharma, North Wales, Pa.) via osmotic pumps for 7 days. On day 10, the osmotic pumps are removed, and the study is continued until day 35.
All animals are euthanized at the termination of the studies by cervical dislocation for gross necropsy, and blood collected by cardiac puncture. The lungs from each animal are dissected from the animal and weighed. The BAL cells and fluid are collected by lavaging the lung twice with 0.5 ml Hanks Balanced Salt Solution (HBSS; VWR, Radnor, Pa.). After collection of BAL cells and fluid, lungs are dissected and removed from each animal. Whole lungs are inflated with 10% NBF and then fixed in 10% NBF for histology. Severity of fibrosis in the lungs is evaluated using a modified Ashcroft score (Hubner, Biotechniques, 2008).
Carbon Tetrachloride-Induced Liver Fibrosis in Mice or Rats
Carbon tetrachloride-induced liver fibrosis is a widely used and accepted model for evaluating novel antifibrotic therapies. The methods for inducing liver fibrosis by carbon tetrachloride administration is described in Lee, J Clin Invest, 1995 and Tsukamoto, Semin Liver Dis, 1990. Briefly, male C57BL/6 mice are challenged with 1 mg/kg carbon tetrachloride (Sigma Aldrich, diluted 1:7 in corn or olive oil) administered by intraperitoneal injection twice weekly for a period of 4 weeks. Mice are euthanized on day 28. In an alternative implementation, Wistar rats are administered carbon tetrachloride by intraperitoneal injection three times per week for 8-12 weeks. Rats are euthanized at the termination of the experiment, 8-12 after study initiation.
Blood is collected by cardiac puncture and processed into serum for evaluation of liver enzymes (including ALT, AST, ALP, etc) at several timepoints throughout the study and at termination of the study. The liver tissues from all animals are collected and fixed by immersion in 10% neutral buffered formalin, processed, paraffin embedded, sectioned, mounted, and stained with Masson's Trichrome (Tri) or Picrosirius Red (PSR) using standard histological methods for evaluation of fibrosis severity.
Mouse Unilateral Ureteral Obstruction Kidney Fibrosis Model
Female C57BL/6 mice (Harlan, 4-6 weeks of age) will be given free access to food and water and allowed to acclimate for at least 7 days prior to test initiation. After acclimation, mice are anesthetized and undergo unilateral ureteral obstruction (UUO) surgery or sham to left kidney. Briefly, a longitudinal, upper left incision is performed to expose the left kidney. The renal artery is located and 6/0 silk thread is passed between the artery and the ureter. The thread is looped around the ureter and knotted 3 times insuring full ligation of ureter. The kidney is returned to abdomen, the abdominal muscle is sutured and the skin is stapled closed. All animals are euthanized 4, 8, 14, 21, or 28 days after UUO surgery. Following sacrifice blood is collected via cardiac puncture, the kidneys are harvested and one half of the kidney is frozen at −80° C. and the other half is fixed in 10% neutral buffered formalin for histopathological assessment of kidney fibrosis.
Bleomycin Dermal Fibrosis Model
Bleomycin (Calbiochem, Billerica Mass.) is dissolved in phosphate buffered saline (PBS) at 10 ug/ml, and sterilized by filtration. Bleomycin or PBS control (100 ul) is injected subcutaneously into two locations on the shaved back of C57/BL6 or S129 mice (Charles River/Harlan Labs, 20-25 g) once daily for 28 days while under isoflourane anesthesia (5% in 100% 02). After 28 days, mice are euthanized and 6 mm-full thickness punch biopsies are obtained from each injection site. Dermal fibrosis is assessed by standard histopathology and hydroxyproline biochemical assays.
Targeting Calpains as a Novel Strategy Towards Inhibition of EpMT
Calpains are calcium dependent non-lysosomal cysteine proteases that selectively cleavage their target substrates, often leaving behind a functional domain and can be a form of post-translational modification. There are currently 14 known genes encoding for the large calpain subunit in humans: CAPN1 (NCBI Gene ID 823), CAPN2 (NCBI Gene ID 824), CAPN3 (NCBI Gene ID 825), CAPN5 (NCBI Gene ID 726), CAPN6 (NCBI Gene ID 827), CAPN7 (NCBI Gene ID 23473), CAPN8 (NCBI Gene ID 388743), CAPN9 (NCBI Gene ID 10753), CAPN10 (NCBI Gene ID 11132), CAPN11 (NCBI Gene ID 11131), CAPN12 (NCBI Gene ID 147968), CAPN13 (NCBI Gene ID 92251), CAPN14 (NCBI Gene ID 440854), CAPN15 (NCBI Gene ID 6650) and 2 known genes for the small regulatory subunits CAPN4/CAPNS1 (NCBI Gene ID 826) and CAPNS2 (NCBI Gene ID 84290) (Goll 2003; Schad 2002). The majority of research has focused on the ubiquitously expressed CAPN1 (aka mu-calpain) and CAPN2 (aka m-calpain), which require micro or millimolar levels of calcium for their activation, respectively. These isoforms, along with CAPN9, have been shown to form a heterodimer with the small regulatory subunit (CAPNS1 aka CAPN4) (Ravulapalli 2009). Calpains have been implicated in numerous cellular processes, including cytoskeletal rearrangement (Dourdin 2001), migration (Leloup 2006), signaling (Janossy 2004), and differentiation (Santos 2012).
For assessment of in vitro EMT, NMuMG cells (ATCC) were grown to confluence in 10% serum (Fetal Bovine Serum) growth media (Dubecco's Modified Eagles Medium supplemented with 10 ug/mL insulin) and then were followed by 24 h starvation in 0.5% serum media+/−drug inhibitors. Cells were then treated with recombinant human TGFb1 (R&D Systems 5 ng/mL)+/−drug inhibitors in 0.5% serum media. For time points greater than 24 h, the aforementioned media was refreshed every 24 hours. Cell lysates were analyzed for aSMA protein expression by western blot.

For assessment of in vitro FMT, Normal Human Lung Fibroblasts (NHLF) cells (Lonza) were grown in Fibroblast Growth Media-2 (Lonza CC-3131/with CC-4126 bullet kit) and then were followed by 24 h starvation in serum/growth factor free Fibroblast Basal Media-2 (Lonza CC-3131)+/−drug inhibitors. Cells were then treated with TGFb1 (5 ng/mL) Fibroblast Basal Media+/−drug inhibitors. Cell lysates were analyzed for aSMA protein expression by western blot.
