  • MAPKs Mitogen-activated protein kinases
  • MAPK networks are critical for the transmission of extracellular signals into appropriate intracellular responses, such as, but not limited to cell growth, differentiation, inflammation, and apoptosis.
  • Prototypical MAPK activation employs a three-kinase core module consisting of a MAPK kinase kinase (MAPKKK or MAP3K) that phosphorylates and activates a MAPK kinase (MAP2K, MEK, or MKK) that in turn phosphorylates and dramatically increases the activity of one or more MAPKs.
  • MAPKKK MAPK kinase kinase
  • MAP2K MAPK kinase kinase
  • MEK MEK
  • MKK MAPK kinase kinase
  • Apoptosis signal-regulating kinase 1 is a member of the MAP3K family that activates the c-Jun N-terminal protein kinase (JNK) and p38 MAPK.
  • ASK1 also known as mitogen-activated protein kinase kinase kinase 5 (MAP3K5), is activated by a variety of stimuli including hyperglycaemia, transforming growth factor beta (TGF- ⁇ ), oxidative stress, reactive oxygen species (ROS), lipopolysaccharides (LPS), tumor necrosis factor alpha (T Fa), Fas ligand (FasL), endoplasmic reticulum (ER) stress, and increased intracellular calcium concentrations.
  • TGF- ⁇ transforming growth factor beta
  • ROS reactive oxygen species
  • LPS lipopolysaccharides
  • T Fa tumor necrosis factor alpha
  • FasL Fas ligand
  • ER endoplasmic reticulum
  • ROS have been reported to be associated with increase of inflammatory cytokine production, fibrosis, apoptosis, and necrosis in the kidney. Moreover, oxidative stress facilitates the formation of advanced glycation end-products (AGEs) that cause further renal injury and production of ROS. ASKl induces apoptosis, fibrosis and metabolic dysfunction by activating the p38 and JNK1 pathways.
  • ASKl undergoes activation via autophosphorylation at Thr838 in response to these signals and in turn phosphorylates MAP2Ks, such as MKK3/6 and MKK4/7, which then phosphorylate and activates p38 and JNK MAPKs, respectively.
  • ASK2 is a related MAP3K that shares 45% sequence homology with ASKl .
  • ASK2 tissue distribution is restricted, in some cell types ASKl and ASK2 have been reported to interact and function together in a protein complex. In non-stressed conditions, ASKl is kept in an inactive state through binding to its repressor thioredoxin (Trx) and through association with AKT.
  • Trx repressor thioredoxin
  • ASKl protein can lead to apoptosis or other cellular responses depending on the cell type.
  • ASKl activation and signaling have been reported to play a role in a broad range of diseases including fibrosis, neurodegenerative, cardiovascular, inflammatory, autoimmunity, and metabolic disorders.
  • ASKl has been implicated in mediating organ damage following ischemia and reperfusion of the heart, brain, liver and kidney.
  • Fibrosis is a wound-healing process in which there is excessive deposition of extracellular matrix (ECM).
  • ECM is composed of collagens, noncollagen glycoproteins, matrix bound growth factors, glycosaminoglycans, proteoglycans and matricellular proteins, which provide the scaffolding of both the normal and the fibrotic tissues.
  • glycoproteins e.g. cellular fibronectin, laminin, SPARC, osteonectin, tenascin and von Willebrand factor

  • the fibrotic condition is liver fibrosis.
  • Liver fibrosis refers to the scar tissue and nodules that replace liver tissue and disrupt liver function.
  • the scar tissue blocks the portal flow of blood through the organ therefore disturbing normal function. Damage to the hepatic parenchyma due to inflammation leads to activation of the stellate cell, which increases fibrosis through production of myofibroblasts and obstructs blood flow in the circulation.
  • Non-alcoholic fatty liver disease is a common liver disease characterized by fat accumulation in hepatocytes that is not linked to excessive alcohol intake and is correlated with obesity, insulin resistance, and cardiac diseases.
  • NAFLD is categorised into simple steatosis and non-alcoholic steatotic hepatitis (NASH), the latter of which can lead to hepatic fibrosis, hepatic cirrhosis, and liver cancer.
  • High fat diet (HFD) is used to induce hepatic steatosis in mouse models. HFD causes fat accumulation and fatty acid oxidation, which leads to ROS generation and subsequent hepatocyte dysfunction and cell death in the liver.
  • TNFa-deficient mice show reduced hepatic steatosis, indicating that proinflammatory cytokines including TNFa are required for liver injury.
  • TNFa-induced apoptosis of hepatocytes is mediated by ASK1-JNK activation.
  • ASKl -deficient mice have reduced HFD-induced hepatic steatosis, fibrosis, and TGFp expression, which is responsible for hepatic fibrosis.

DETAILED DESCRIPTION OF THE INVENTION
[0024] Mitogen-activated protein kinases (MAPKs) are a highly conserved family of serine/threonine protein kinases involved in a variety of fundamental cellular processes such as proliferation, differentiation, motility, stress response, apoptosis, and survival. MAPK networks are critical for the transmission of extracellular signals into appropriate intracellular responses, such as, but not limited to cell growth, differentiation, inflammation, and apoptosis. Prototypical MAPK activation employs a three-kinase core module consisting of a MAPK kinase kinase (MAPKKK or MAP3K) that phosphorylates and activates a MAPK kinase (MAP2K, MEK, or MKK) that in turn phosphorylates and dramatically increases the activity of one or more MAPKs.
[0025] Apoptosis signal-regulating kinase 1 (ASK1) is a member of the MAP3K family that activates the c-Jun N-terminal protein kinase (JNK) and p38 MAPK. ASK1, also known as mitogen-activated protein kinase kinase kinase 5 (MAP3K5), is activated by a variety of stimuli including hyperglycaemia, transforming growth factor beta (TGF-β), oxidative stress, reactive oxygen species (ROS), lipopolysaccharides (LPS), tumor necrosis factor alpha (T Fa), Fas ligand (FasL), endoplasmic reticulum (ER) stress, and increased intracellular calcium concentrations. ROS have been reported to be associated with increase of inflammatory cytokine production, fibrosis, apoptosis, and necrosis in the kidney. Moreover, oxidative stress facilitates the formation of advanced glycation end-products (AGEs) that cause further renal injury and production of ROS. ASKl induces apoptosis, fibrosis and metabolic dysfunction by activating the p38 and JNK1 pathways.
[0026] ASKl undergoes activation via autophosphorylation at Thr838 in response to these signals and in turn phosphorylates MAP2Ks, such as MKK3/6 and MKK4/7, which then phosphorylate and activates p38 and JNK MAPKs, respectively. ASK2 is a related MAP3K that shares 45% sequence homology with ASKl . Although ASK2 tissue distribution is restricted, in some cell types ASKl and ASK2 have been reported to interact and function together in a protein complex. In non-stressed conditions, ASKl is kept in an inactive state through binding to its repressor thioredoxin (Trx) and through association with AKT.
[0027] Phosphorylation of ASKl protein can lead to apoptosis or other cellular responses depending on the cell type. ASKl activation and signaling have been reported to play a role in a broad range of diseases including fibrosis, neurodegenerative, cardiovascular, inflammatory, autoimmunity, and metabolic disorders. In addition, ASKl has been implicated in mediating organ damage following ischemia and reperfusion of the heart, brain, liver and kidney.
Fibrosis
[0028] Fibrosis is a wound-healing process in which there is excessive deposition of extracellular matrix (ECM). ECM is composed of collagens, noncollagen glycoproteins, matrix bound growth factors, glycosaminoglycans, proteoglycans and matricellular proteins, which provide the scaffolding of both the normal and the fibrotic tissues. However, as fibrosis develops, there are multiple changes in the specific contents of these, with a marked increase in total collagen content; an increase in glycoproteins (e.g. cellular fibronectin, laminin, SPARC, osteonectin, tenascin and von Willebrand factor) and glycosaminoglycans (e.g. perlecan, decorin, aggrecan, lumican and fibromodulin); both an increase in proteoglycans and a shift from heparan sulphate containing proteoglycans to those containing chondroitin and dermatan sulphates; and an increase in the fibril -forming collagens types I, III and V and in some nonfibril -forming collagens (types IV and VI). For example, with all of these changes occurring in the liver, there is a transition from the low-density basement membrane-like matrix in the subendothelial space that is found in the normal liver to the interstitial type which is associated with hepatocyte dysfunction and activation of the hepatic stellate cells (HSCs), which are the primary source of ECM in both the normal and fibrotic liver. During activation, HSCs transition from their normal quiescent state to proliferative, fibrogenic and contractile myofibroblasts. [0029] Non-alcoholic steatotic hepatitis (NASH) is an exemplary type of fibrosis implicating ASK1 activity. Multiple pathways are involved in NASH-associated fibrosis including inflammasome-TLR activation and generation of the inflammatory cytokines, increased levels of hedgehog signalling, changes in lipid and glucose metabolism leading to oxidative stress, hepatocyte injury via apoptosis, cell death inducing inflammatory and pro-fibrogenic pathways in nonparenchymal cells and infiltrating immune cells. These processes lead to HSC activation which is the source of excessive deposition of extracellular matrix (ECM) in the parenchyma.
[0030] In some embodiments, disclosed herein are methods of treating fibrosis with a compound disclosed herein.
[0031] "Fibrosis," as used herein, refers to the accumulation of extracellular matrix constituents that occurs following trauma, inflammation, tissue repair, immunological reactions, cellular hyperplasia, and neoplasia. Fibrosis may refer to the development of fibrous connective tissue as a reparative response to injury or damage. Fibrosis may also refer to the connective tissue deposition that occurs as part of normal healing or to the excess tissue deposition that occurs as a pathological process.
[0032] In some embodiments, disclosed herein is a method of reducing fibrosis in a tissue comprising contacting a fibrotic cell or tissue with a compound disclosed herein, in an amount sufficient to decrease or inhibit the fibrosis. In some embodiments, the fibrosis includes a fibrotic condition.
[0033] In some embodiments, the fibrosis comprises liver fibrosis, kidney fibrosis, lung fibrosis, cardiac fibrosis, peritoneal fibrosis, ocular fibrosis or cutaneous fibrosis. In some embodiments, the fibrosis comprises liver fibrosis. In some embodiments, the fibrosis comprises kidney fibrosis. In some embodiments, the fibrosis comprises cardiac fibrosis. In some embodiments, the fibrosis comprises lung fibrosis. In some embodiments, the fibrosis comprises peritoneal fibrosis. In some embodiments, the fibrosis comprises ocular fibrosis. In some embodiments, the fibrosis comprises cutaneous fibrosis.
[0034] In some embodiments, reducing fibrosis, or treatment of a fibrotic condition, includes reducing or inhibiting one or more of: formation or deposition of extracellular matrix proteins; the number of pro-fibrotic cell types (e.g., fibroblast or immune cell numbers); cellular collagen or hydroxyproline content within a fibrotic lesion; expression or activity of a fibrogenic protein; or reducing fibrosis associated with an inflammatory response.
[0035] In some embodiments, the fibrotic condition is liver fibrosis. Liver fibrosis refers to the scar tissue and nodules that replace liver tissue and disrupt liver function. The scar tissue blocks the portal flow of blood through the organ therefore disturbing normal function. Damage to the hepatic parenchyma due to inflammation leads to activation of the stellate cell, which increases fibrosis through production of myofibroblasts and obstructs blood flow in the circulation.
Production of myofibroblasts accelerates the loss of liver function and can lead to death.
[0036] Non-alcoholic fatty liver disease (NAFLD) is a common liver disease characterized by fat accumulation in hepatocytes that is not linked to excessive alcohol intake and is correlated with obesity, insulin resistance, and cardiac diseases. NAFLD is categorised into simple steatosis and non-alcoholic steatotic hepatitis (NASH), the latter of which can lead to hepatic fibrosis, hepatic cirrhosis, and liver cancer. High fat diet (HFD) is used to induce hepatic steatosis in mouse models. HFD causes fat accumulation and fatty acid oxidation, which leads to ROS generation and subsequent hepatocyte dysfunction and cell death in the liver. TNFa-deficient mice show reduced hepatic steatosis, indicating that proinflammatory cytokines including TNFa are required for liver injury. TNFa-induced apoptosis of hepatocytes is mediated by ASK1-JNK activation. ASKl -deficient mice have reduced HFD-induced hepatic steatosis, fibrosis, and TGFp expression, which is responsible for hepatic fibrosis. Olmesartan, an ATI blocker, also improves HFD-induced hepatic steatosis by inhibiting ASKl . Moreover, olmesartan or ASKl deficiency can attenuate HFD-induced cardiac inflammation and fibrosis, and vascular endothelial dysfunction and remodelling. These findings suggest that ASKl is involved in obesity-associated cardiovascular complications and hepatic steatosis.
[0037] The ASKl pathway has been shown to be activated in human NASH liver biopsies. In animals with established NASH (Fl/2), a small molecule inhibitor of ASKl significantly reduced hepatic steatosis and fibrosis and significantly improved key metabolic parameters associated with NASH. Treatment with a small molecule inhibitor of ASKl resulted in a significant reduction in body weight; decreased fasting blood glucose and insulin levels; reduction in plasma AST, ALT and cholesterol levels; a reduction in hepatic steatosis; a reduction in liver
hydroxyproline; a reduction in alpha smooth muscle actin and p-P38 expression; a reduction in fibrillar collagen area and reduced synthesis of collagen. ASKl inhibition also reduced hepatic fibrosis, steatosis and insulin resistance and normalised fatty acid synthesis and lipid metabolism.
[0038] In some embodiments, the fibrotic condition is a fibrotic condition of the lung. Lung or pulmonary fibrosis refers to a number of conditions that cause interstitial lung damage, followed by accumulation of extracellular matrix constituents and eventually loss of lung elasticity and function. These conditions lead to symptoms such as persistent coughing, chest pain, difficulty breathing and fatigue. Lung fibrosis may occur as a secondary condition in various diseases.
[0039] In some embodiments, the fibrotic condition is a fibrotic condition of the heart. Cardiac fibrosis refers to the damage of the heart areas due to myocardial infarction or Davies' disease. Cardiac fibrosis can affect the valves in the heart as well as the muscles, which become stiff and less compliant. This can increase the risk of heart failure. [0040] In some embodiments, the fibrotic condition is a fibrotic condition of the kidney.
Kidney fibrosis refers to an excessive accumulation of extracellular matrix that occurs in virtually every type of chronic kidney disease. The pathogenesis of renal fibrosis is a progressive process that ultimately leads to end-stage renal failure, a devastating disorder that requires dialysis or kidney transplantation. Several cellular pathways, including mesangial and fibroblast activation as well as tubular epithelial -mesenchymal transition, have been identified as the major ways for the generation of the matrix-producing cells in diseased conditions. Among many fibrogenic factors that regulate renal fibrotic process, transforming growth factor-beta (TGF- beta) is one that plays a central role. Although defective matrix degradation may contribute to tissue scarring, the exact action and mechanisms of the matrix-degrading enzymes in the injured kidney have become increasingly complicated.
[0041] In some embodiments, the fibrotic condition is a fibrotic condition of the skin.
[0042] In some embodiments, the fibrotic condition is a fibrotic condition of the eye.
[0043] In some embodiments, the fibrotic condition is a fibrotic condition of the
gastrointestinal tract.
[0044] In some embodiments, the fibrotic condition is a fibrotic condition of the bone marrow.
[0045] In some embodiments, the fibrotic condition is idiopathic. In some embodiments, the fibrotic condition is associated with (e.g., is secondary to) a disease (e.g., an infectious disease, an inflammatory disease, an autoimmune disease, a malignant or cancerous disease, and/or a connective disease); a toxin; an insult (e.g., an environmental hazard (e.g., asbestos, coal dust, polycyclic aromatic hydrocarbons), cigarette smoking, a wound); a medical treatment (e.g., surgical incision, chemotherapy or radiation), or a combination thereof.
[0046] In some embodiments, disclosed herein is a method for the treatment or prevention of fibrosis in a mammal comprising administering an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof, to the mammal in need thereof.
[0047] In some embodiments, disclosed herein is a method of improving lung function in a mammal comprising administering an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof, to the mammal in need thereof. In some embodiments, the mammal has been diagnosed as having lung fibrosis.
[0048] In some embodiments, disclosed herein is a method of treating idopathic pulmonary fibrosis in a mammal comprising administering an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof, to the mammal in need thereof.
[0049] In some embodiments, disclosed herein is a method of controlling an abnormal accumulation or activation of cells, fibronectin, collagen or increased fibroblast recruitment in a tissue of a mammal comprising administering an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof, to the mammal in need thereof. In some embodiments, the abnormal accumulation or activation of cells, fibronectin, collagen or increased fibroblast recruitment in the tissue results in fibrosis.
[0050] In some embodiments, disclosed herein is a method for the treatment or prevention of scleroderma in a mammal comprising administering an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof, to the mammal in need thereof.
[0051] In some embodiments, disclosed herein is a method for reducing undesired or abnormal dermal thickening in a mammal comprising administering to mammal in need thereof an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof. In some embodiments, the dermal thickening is associated with scleroderma.
[0052] In some embodiments, described herein is a method of controlling an abnormal accumulation or activation of cells, fibronectin, collagen or increased fibroblast recruitment in tissues of a mammal comprising administering to mammal in need thereof an ASK1 inhibitor described herein, or a pharmaceutically acceptable salt thereof. In some embodiments, the abnormal accumulation or activation of cells, fibronectin, collagen or increased fibroblast recruitment in the dermal tissues results in fibrosis. In some embodiments, described herein is a method of reducing hydroxyproline content in tissues of a mammal with fibrosis comprising administering to mammal in need thereof an ASK1 inhibitor described herein, or a
pharmaceutically acceptable salt thereof.
[0053] In some embodiments, compounds described herein are used in the treatment of fibrosis associated with arthrofibrosis, Crohn's Disease, Dupuytren's contracture, keloids, myelofibrosis, Peyronie's disease, or scleroderma/systemic sclerosis.
[0054] In some embodiments, anti-fibrotic strategies include (i) removing the injurious stimuli, (ii) suppressing or modulating inflammation, (iii) protecting the organ at risk of developing fibrosis, and (v) promoting matrix degradation. Some of these strategies have direct effect on fibrosis pathway, while others may have indirect effect. In some embodiments, anti-fibrotic strategies in NASH include (a) removing the injurious stimuli, (b) suppressing or modulating hepatic inflammation, (c) protecting the liver, (d) downregulating stellate cell activation and (e) promoting matrix degradation.
[0055] Fibrosis, such as hepatic fibrosis in NASH, is driven by multiple risk factors that may interact with each other via several inter-related mechanistic pathways. It is plausible that the injurious stimuli may be heterogenous, but the resultant response in laying down of collagen and worsening of fibrosis may be a common response. In some embodiments, multiple targets may be required to reverse or halt fibrosis. Removal of cause would be the most efficient way to improve fibrosis. This has been supported by observations seen with other chronic diseases, including hepatitis C and B.
[0056] In some embodiments, compounds described herein are dual inhibitors and inhibit the activity of ASK1 and at least one other fibrosis promoting protein. In some embodiments, compounds described herein inhibit the activity of ASK1 and LOXL2.
[0057] Lysyl oxidase like-2 (LOXL2) is a member of the lysyl oxidase (LOX) family, which comprises Cu2+ and lysine tyrosylquinone (LTQ)-dependent amine oxidases. The family comprises five genes: lox (LOX), /ox/7 (lysyl oxidase like-1, LOXL1), loxl2 (LOXL2), loxl3 (lysyl oxidase like-3, LOXL3), and loxl4 (lysyl oxidase like-4, LOXL4). The LOX family is known for catalyzing the oxidative deamination of the ε-amino group of lysines and
hydroxylysines in collagen and elastin to promote crosslinking of these molecules. Crosslinking of collagen and elastin is essential for maintaining tensile strength of the extracellular matrix.
[0058] LOXL2 has been demonstrated to have intracellular functions aside from its role in remodeling of the extracellular matrix. LOXL2 positively regulates the epithelial-to- mesenchymal transition (EMT) transducer, Snail 1, by promoting Snail 1 stability and functional activity. LOXL2 contributes positively to the activation of the focal adhesion kinase (FAK) signaling pathway and participates in the organization of focal adhesion complexes. Silencing of LOXL2 gene leads to reacquisition of epithelial cell polarity and decreases the migratory and invasive ability of mammary cell lines. The modulation of cell adhesion and cell polarity has been reported to be mediated by intracellular LOXL2. LOXL2 transcriptionally represses E- cadherin as well as tight junction and cell polarity genes by Snail 1 -dependent and Snail 1- independent mechanisms. LOXL2 has been more recently described to be associated with chromatin and reported to be involved in histone H3 deamination, a function that is dependent on the LOXL2 catalytic domain.
[0059] LOXL2 has been shown to be involved in fibrotic processes. Fibrotic processes include an excessive deposition of extracellular matrix components, such as collagen, which alters the physical, biochemical and biomechanical matrix properties leading to defective organ function and organ failure. Tissue fibrosis is also associated with cancer progression by direct promotion of cellular transformation and metastasis. Tumors are typically stiffer than normal tissue and tumor rigidity influences tumor metastasis.
[0060] Excessive LOXL2 enzyme activity has been implicated in the increased stiffness of tumors. Elevated LOXL2 is also associated with fibrotic lesions from livers of patients suffering from diseases or conditions such as, but not limited to, Wilson disease, primary biliary cirrhosis, PSC, NAFLD and NASH. Additionally, the administration of a LOXL2-specific monoclonal antibody AB0023 was efficacious in reducing disease in a model of fibrosis. AB0023 was shown to inhibit the production of growth factors and of crosslinked collagenous matrix and TGF-beta signaling.
[0061] Cardiovascular diseases. Cardiovascular diseases include, but are not limited to, ischaemia/reperfusion injury, cardiac remodelling, and vascular endothelial dysfunction.
[0062] In some embodiments, compounds described herein are used in the treatement of diseases of the retina.
[0063] In some embodiments, compounds described herein are used in the treatement of diseases of the spinal cord.
[0064] During myocardial infarction, some cardiomyocytes undergo necrosis due to a shortage of oxygen and nutrition, which causes low cardiac output. To compensate for this loss of cardiac function, surviving cardiomyocytes undergo changes in size and location, which is referred to as cardiac hypertrophy. Sustained hypertension and diabetic cardiomyopathy can also induce cardiac hypertrophy. In ventricular hypertrophy, gene reprogramming and accumulation of extracellular matrix proteins are involved in ventricular fibrosis and remodelling. In some embodiments, ASKl plays a role in the pathogenesis of ventricular remodelling by promoting apoptosis or cardiomyocyte hypertrophy. In some other embodiments, ASKl is aldosterone- induced cardiac inflammation and fibrosis through induction of monocyte chemoattractant protein (MCP)-l and transforming growth factor (TGF)-pi expression, respectively.
[0065] In some embodiments, compounds described herein are used in the treatement of neurodegenerative disorders. Neurodegenerative disorders include, but are not limited to, Huntington's disease (HD), spinobulbar muscular atrophy, spinocerebeller ataxia (SCA), Amyotrophic lateral sclerosis (ALS), Alzheimer's disease, Parkinson's disease, Normal -tension glaucoma.
[0066] In some embodiments, compounds described herein are used in the treatement of inflammatory diseases. Inflammatory diseases include, but are not limited to, multiple sclerosis, rheumatoid arthritis.
[0067] In some embodiments, compounds described herein are used in the treatement of respiratory diseases. ASKl also plays a role in airway remodelling, an irreversible hypertrophic change that occurs in chronic bronchitis. Leukotriene D4 has been suggested to activate ASKl and induce AP-1 activation in airway smooth muscle cells, leading to airway remodelling.
Respiratory diseases include, but are not limited to, chronic obstructive pulmonary disease (COPD), asthmas and acute lung injury.
[0068] In some embodiments, compounds described herein are used in the treatement of diabetes. TNFa is one of the factors that aggravate insulin resistance. In hepatocytes, TNFa induces ROS production in the mitochondria and activates JNK via ASKl, which leads to insulin receptor substrate-1 (IRS-1) serine phosphorylation. Such phosphorylation decreases tyrosine phosphorylation of IRS-1 resulting in insulin resistance and eventually causing type 2 diabetes.
[0069] In some embodiments, compounds described herein are used in the treatement of liver linjury. Consumption of large quantities of acetaminophen, a widely used analgesic and antipyretic agent, is known to cause liver injury. In ASKl -deficient mice, acetaminophen- induced, sustained activation of INK is suppressed and resistance to liver injury increased, indicating that the ASKl -INK pathway plays a critical role in acetaminophen-induced liver injury. ASKl has also been reported to be involved in liver injury induced by troglitazone, a first- generation thiazolidinedione insulin sensitizer that has been linked to an unacceptable risk of liver injury in patients.
[0070] In some embodiments, compounds described herein are used in the treatement of ageing. ROS is thought to be one of the major causes of ageing. Consistent with this notion, long- lived mouse models, such as Snell dwarf mice, Ames dwarf mice, and Klotho overexpressing mice, are known to be resistant to oxidative stress. Mouse embryonic fibroblasts (MEFs) derived from Ames dwarf mice possess a larger amount of the Trx -bound form of ASKl and have less p38 activity than those derived from WT mice, suggesting that activity of the ASKl-p38 pathway is attenuated in Ames dwarf mice. Also, in the livers of Klotho overexpressing mice, the activity of the ASKl-p38 pathway and the amount of Trx -bound ASKl are decreased and increased, respectively, whereas the opposite is observed in liver extracts from Klotho-deficient mice. In some embodiments, ROS-induced ASKl activity contributes to regulation of ageing-related cellular functions.

[00141] Compounds in Table 2 are named:
4-((4-(Aminomethyl)-6-(trifluoromethyl)pyridin-2-yl)oxy)-N-(3-(4-cyclopropyl-4H-l,2,4-triazol- 3-yl)phenyl)picolinamide (Compound 2-1).
[00142] In some embodiments, provided herein is a pharmaceutically acceptable salt or solvate of a compound that is described in Table 2.
[00143] Any combination of the groups described above for the various variables is
contemplated herein. Throughout the specification, groups and substituents thereof are chosen by one skilled in the field to provide stable moieties and compounds.
[00144] In one aspect, compounds described herein are in the form of pharmaceutically acceptable salts. As well, active metabolites of these compounds having the same type of activity are included in the scope of the present disclosure. In addition, the compounds described herein can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. The solvated forms of the compounds presented herein are also considered to be disclosed herein.
[00145] "Pharmaceutically acceptable," as used herein, refers a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the compound, and is relatively nontoxic, i.e., the material is administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained. [00146] The term "pharmaceutically acceptable salt" refers to a form of a therapeutically active agent that consists of a cationic form of the therapeutically active agent in combination with a suitable anion, or in alternative embodiments, an anionic form of the therapeutically active agent in combination with a suitable cation. Handbook of Pharmaceutical Salts: Properties, Selection and Use. International Union of Pure and Applied Chemistry, Wiley-VCH 2002. S.M. Berge, L.D. Bighley, D.C. Monkhouse, J. Pharm. Sci. 1977, 66, 1-19. P. H. Stahl and C. G. Wermuth, editors, Handbook of Pharmaceutical Salts: Properties, Selection and Use,
Weinheim/Zurich:Wiley-VCH/VHCA, 2002. Pharmaceutical salts typically are more soluble and more rapidly soluble in stomach and intestinal juices than non-ionic species and so are useful in solid dosage forms. Furthermore, because their solubility often is a function of pH, selective dissolution in one or another part of the digestive tract is possible and this capability can be manipulated as one aspect of delayed and sustained release behaviours. Also, because the salt- forming molecule can be in equilibrium with a neutral form, passage through biological membranes can be adjusted.
[00147] In some embodiments, pharmaceutically acceptable salts are obtained by reacting a compound described herein with an acid. In some embodiments, the compound described herein (i.e. free base form) is basic and is reacted with an organic acid or an inorganic acid. Inorganic acids include, but are not limited to, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, nitric acid, and metaphosphoric acid. Organic acids include, but are not limited to, l-hydroxy-2-naphthoic acid; 2,2-dichloroacetic acid; 2-hydroxyethanesulfonic acid; 2- oxoglutaric acid; 4-acetamidobenzoic acid; 4-aminosalicylic acid; acetic acid; adipic acid;

[00148] In some embodiments, a compound described herein is prepared as a chloride salt, sulfate salt, bromide salt, mesylate salt, maleate salt, citrate salt or phosphate salt. In some embodiments, a compound described herein is prepared as a hydrochloride salt.
[00149] In some embodiments, pharmaceutically acceptable salts are obtained by reacting a compound described herein with a base. In some embodiments, the compound described herein is acidic and is reacted with a base. In such situations, an acidic proton of the compound described herein is replaced by a metal ion, e.g., lithium, sodium, potassium, magnesium, calcium, or an aluminum ion. In some cases, compounds described herein coordinate with an organic base, such as, but not limited to, ethanolamine, diethanolamine, triethanolamine, tromethamine, meglumine, N-methylglucamine, dicyclohexylamine,
tris(hydroxymethyl)methylamine. In other cases, compounds described herein form salts with amino acids such as, but not limited to, arginine, lysine, and the like. Acceptable inorganic bases used to form salts with compounds that include an acidic proton, include, but are not limited to, aluminum hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium hydroxide, lithium hydroxide, and the like. In some embodiments, the compounds provided herein are prepared as a sodium salt, calcium salt, potassium salt, magnesium salt, meglumine salt, N-methylglucamine salt or ammonium salt. In some embodiments, the compounds provided herein are prepared as a sodium salt.
[00150] It should be understood that a reference to a pharmaceutically acceptable salt includes the solvent addition forms. In some embodiments, solvates contain either stoichiometric or non- stoichiometric amounts of a solvent, and are formed during the process of crystallization with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Solvates of compounds described herein are conveniently prepared or formed during the processes described herein. In addition, the compounds provided herein optionally exist in unsolvated as well as solvated forms.
[00151] The methods and formulations described herein include the use of N-oxides (if appropriate), crystalline forms (also known as polymorphs), or pharmaceutically acceptable salts of compounds described herein, as well as active metabolites of these compounds having the same type of activity.
[00152] In some embodiments, sites on the organic radicals (e.g. alkyl groups, aromatic rings) of compounds described herein are susceptible to various metabolic reactions. Incorporation of appropriate substituents on the organic radicals will reduce, minimize or eliminate this metabolic pathway. In specific embodiments, the appropriate substituent to decrease or eliminate the susceptibility of the aromatic ring to metabolic reactions is, by way of example only, a halogen, deuterium, an alkyl group, a haloalkyl group, or a deuteroalkyl group.
[00153] In another embodiment, the compounds described herein are labeled isotopically (e.g. with a radioisotope) or by another other means, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels.
[00154] Compounds described herein include isotopically-labeled compounds, which are identical to those recited in the various formulae and structures presented herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the present compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, fluorine and chlorine, such as, for example, 2H, 3H, 13C, 14C, 15N, 180, 170, 35 S, 18F, 36C1. In one aspect, isotopically-labeled compounds described herein, for example those into which radioactive isotopes such as 3H and 14C are incorporated, are useful in drug and/or substrate tissue distribution assays. In one aspect, substitution with isotopes such as deuterium affords certain therapeutic advantages resulting from greater metabolic stability, such as, for example, increased in vivo half-life or reduced dosage requirements.
[00155] In some embodiments, the compounds described herein possess one or more stereocenters and each stereocenter exists independently in either the R or S configuration. The compounds presented herein include all diastereomeric, enantiomeric, atropisomers, and epimeric forms as well as the appropriate mixtures thereof. The compounds and methods provided herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the appropriate mixtures thereof.
[00156] Individual stereoisomers are obtained, if desired, by methods such as, stereoselective synthesis and/or the separation of stereoisomers by chiral chromatographic columns. In certain embodiments, compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds/salts, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, resolution of enantiomers is carried out using covalent diastereomeric derivatives of the compounds described herein. In another embodiment, diastereomers are separated by separation/resolution techniques based upon differences in solubility. In other embodiments, separation of steroisomers is performed by chromatography or by the forming diastereomeric salts and separation by recrystallization, or chromatography, or any combination thereof. Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers,
Racemates and Resolutions", John Wiley and Sons, Inc., 1981. In some embodiments, stereoisomers are obtained by stereoselective synthesis. [00157] In some embodiments, compounds described herein are prepared as prodrugs. A "prodrug" refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they are easier to administer than the parent drug. They are, for instance, bioavailable by oral administration whereas the parent is not. The prodrug may be a substrate for a transporter. Further or alternatively, the prodrug also has improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. An example, without limitation, of a prodrug is a compound described herein, which is administered as an ester (the "prodrug") but then is metabolically hydrolyzed to provide the active entity. A further example of a prodrug is a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound.
[00158] Prodrugs of the compounds described herein include, but are not limited to, esters, ethers, carbonates, thiocarbonates, N-acyl derivatives, N-acyloxy alkyl derivatives, quaternary derivatives of tertiary amines, N-Mannich bases, Schiff bases, amino acid conjugates, phosphate esters, and sulfonate esters. See for example Design of Prodrugs, Bundgaard, A. Ed., Elseview, 1985 and Method in Enzymology, Widder, K. et al, Ed.; Academic, 1985, vol. 42, p. 309-396; Bundgaard, H. "Design and Application of Prodrugs" in A Textbook of Drug Design and Development, Krosgaard-Larsen and H. Bundgaard, Ed., 1991, Chapter 5, p. 113-191; and Bundgaard, H., Advanced Drug Delivery Review, 1992, 8, 1-38, each of which is incorporated herein by reference. In some embodiments, a hydroxyl group in the compounds disclosed herein is used to form a prodrug, wherein the hydroxyl group is incorporated into an acyloxyalkyl ester, alkoxycarbonyloxyalkyl ester, alkyl ester, aryl ester, phosphate ester, sugar ester, ether, and the like. In some embodiments, a hydroxyl group in the compounds disclosed herein is a prodrug wherein the hydroxyl is then metabolized in vivo to provide a carboxylic acid group. In some embodiments, a carboxyl group is used to provide an ester or amide (i.e. the prodrug), which is then metabolized in vivo to provide a carboxylic acid group. In some embodiments, compounds described herein are prepared as alkyl ester prodrugs.
[00159] Prodrug forms of the herein described compounds, wherein the prodrug is metabolized in vivo to produce a compound described herein as set forth herein are included within the scope of the claims. In some cases, some of the herein-described compounds is a prodrug for another derivative or active compound. [00160] In additional or further embodiments, the compounds described herein are metabolized upon administration to an organism in need to produce a metabolite that is then used to produce a desired effect, including a desired therapeutic effect.
[00161] A "metabolite" of a compound disclosed herein is a derivative of that compound that is formed when the compound is metabolized. The term "active metabolite" refers to a biologically active derivative of a compound that is formed when the compound is metabolized. The term "metabolized," as used herein, refers to the sum of the processes (including, but not limited to, hydrolysis reactions and reactions catalyzed by enzymes) by which a particular substance is changed by an organism. Thus, enzymes may produce specific structural alterations to a compound. For example, cytochrome P450 catalyzes a variety of oxidative and reductive reactions while uridine diphosphate glucuronyltransferases catalyze the transfer of an activated glucuronic-acid molecule to aromatic alcohols, aliphatic alcohols, carboxylic acids, amines and free sulphydryl groups. Metabolites of the compounds disclosed herein are optionally identified either by administration of compounds to a host and analysis of tissue samples from the host, or by incubation of compounds with hepatic cells in vitro and analysis of the resulting compounds.

Pharmaceutical compositions
[00220] In some embodiments, the compounds described herein are formulated into
pharmaceutical compositions. Pharmaceutical compositions are formulated in a conventional manner using one or more pharmaceutically acceptable inactive ingredients that facilitate processing of the active compounds into preparations that are used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. A summary of pharmaceutical compositions described herein is found, for example, in Remington: The Science and Practice of Pharmacy, Nineteenth Ed (Easton, Pa. : Mack Publishing Company, 1995); Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania 1975;
Liberman, H.A. and Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, New York, N.Y., 1980; and Pharmaceutical Dosage Forms and Drug Delivery Systems, Seventh Ed. (Lippincott Williams & Wilkinsl999), herein incorporated by reference for such disclosure.
[00221] In some embodiments, the compounds described herein are administered either alone or in combination with pharmaceutically acceptable carriers, excipients or diluents, in a
pharmaceutical composition. Administration of the compounds and compositions described herein can be effected by any method that enables delivery of the compounds to the site of action. These methods include, though are not limited to delivery via enteral routes (including oral, gastric or duodenal feeding tube, rectal suppository and rectal enema), parenteral routes
(injection or infusion, including intraarterial, intracardiac, intradermal, intraduodenal, intramedullary, intramuscular, intraosseous, intraperitoneal, intrathecal, intravascular, intravenous, intravitreal, epidural and subcutaneous), inhalational, transdermal, transmucosal, sublingual, buccal and topical (including epicutaneous, dermal, enema, eye drops, ear drops, intranasal, vaginal) administration, although the most suitable route may depend upon for example the condition and disorder of the recipient. By way of example only, compounds described herein can be administered locally to the area in need of treatment, by for example, local infusion during surgery, topical application such as creams or ointments, injection, catheter, or implant. The administration can also be by direct injection at the site of a diseased tissue or organ.
[00222] In some embodiments, pharmaceutical compositions suitable for oral administration are presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous liquid or a non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. In some embodiments, the active ingredient is presented as a bolus, electuary or paste.
[00223] Pharmaceutical compositions which can be used orally include tablets, push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. Tablets may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with binders, inert diluents, or lubricating, surface active or dispersing agents. Molded tablets may be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. In some embodiments, the tablets are coated or scored and are formulated so as to provide slow or controlled release of the active ingredient therein. All formulations for oral administration should be in dosages suitable for such administration. The push-fit capsules can contain the active ingredients in admixture with filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In some embodiments, stabilizers are added. Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or Dragee coatings for identification or to characterize different combinations of active compound doses. [00224] In some embodiments, pharmaceutical compositions are formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. The compositions may be presented in unit-dose or multi- dose containers, for example sealed ampoules and vials, and may be stored in powder form or in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example, saline or sterile pyrogen-free water, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.
[00225] Pharmaceutical compositions for parenteral administration include aqueous and nonaqueous (oily) sterile injection solutions of the active compounds which may contain
antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.
[00226] Pharmaceutical compositions may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example, as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
[00227] For buccal or sublingual administration, the compositions may take the form of tablets, lozenges, pastilles, or gels formulated in conventional manner. Such compositions may comprise the active ingredient in a flavored basis such as sucrose and acacia or tragacanth.
[00228] Pharmaceutical compositions may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter, polyethylene glycol, or other glycerides.
[00229] Pharmaceutical compositions may be administered topically, that is by non-systemic administration. This includes the application of a compound of the present invention externally to the epidermis or the buccal cavity and the instillation of such a compound into the ear, eye and nose, such that the compound does not significantly enter the blood stream. In contrast, systemic administration refers to oral, intravenous, intraperitoneal and intramuscular administration.
[00230] Pharmaceutical compositions suitable for topical administration include liquid or semi- liquid preparations suitable for penetration through the skin to the site of inflammation such as gels, liniments, lotions, creams, ointments or pastes, and drops suitable for administration to the eye, ear or nose. The active ingredient may comprise, for topical administration, from 0.001% to 10%) w/w, for instance from 1%> to 2% by weight of the formulation.
[00231] Pharmaceutical compositions for administration by inhalation are conveniently delivered from an insufflator, nebulizer pressurized packs or other convenient means of delivering an aerosol spray. Pressurized packs may comprise a suitable propellant such as dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Alternatively, for administration by inhalation or insufflation, pharmaceutical preparations may take the form of a dry powder composition, for example a powder mix of the compound and a suitable powder base such as lactose or starch. The powder composition may be presented in unit dosage form, in for example, capsules, cartridges, gelatin or blister packs from which the powder may be administered with the aid of an inhalator or insufflator.
[00232] It should be understood that in addition to the ingredients particularly mentioned above, the compounds and compositions described herein may include other agents conventional in the art having regard to the type of formulation in question, for example those suitable for oral administration may include flavoring agents.
Methods of Dosing and Treatment Regimens
[00233] In one embodiment, the compounds described herein, or a pharmaceutically acceptable salt thereof, are used in the preparation of medicaments for the treatment of diseases or conditions in a mammal that would benefit from inhibition or reduction of ASK1 activity.
Methods for treating any of the diseases or conditions described herein in a mammal in need of such treatment, involves administration of pharmaceutical compositions that include at least one compound described herein or a pharmaceutically acceptable salt, active metabolite, prodrug, or pharmaceutically acceptable solvate thereof, in therapeutically effective amounts to said mammal.
[00234] In certain embodiments, the compositions containing the compound(s) described herein are administered for prophylactic and/or therapeutic treatments. In certain therapeutic
applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest at least one of the symptoms of the disease or condition. Amounts effective for this use depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician. Therapeutically effective amounts are optionally determined by methods including, but not limited to, a dose escalation and/or dose ranging clinical trial.
[00235] In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a "prophylactically effective amount or dose." In this use, the precise amounts also depend on the patient's state of health, weight, and the like. When used in patients, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician. In one aspect, prophylactic treatments include administering to a mammal, who previously experienced at least one symptom of the disease being treated and is currently in remission, a pharmaceutical composition comprising a compound described herein, or a pharmaceutically acceptable salt thereof, in order to prevent a return of the symptoms of the disease or condition.
[00236] In certain embodiments wherein the patient's condition does not improve, upon the doctor's discretion the administration of the compounds are administered chronically, that is, for an extended period of time, including throughout the duration of the patient's life in order to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition.
[00237] In certain embodiments wherein a patient's status does improve, the dose of drug being administered is temporarily reduced or temporarily suspended for a certain length of time (i.e., a "drug holiday"). In specific embodiments, the length of the drug holiday is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug holiday is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%.
[00238] Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, in specific embodiments, the dosage or the frequency of administration, or both, is reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. In certain embodiments, however, the patient requires intermittent treatment on a long-term basis upon any recurrence of symptoms. [00239] The amount of a given agent that corresponds to such an amount varies depending upon factors such as the particular compound, disease condition and its severity, the identity (e.g., weight, sex) of the subject or host in need of treatment, but nevertheless is determined according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated.
[00240] In general, however, doses employed for adult human treatment are typically in the range of 0.01 mg-5000 mg per day. In one aspect, doses employed for adult human treatment are from about 1 mg to about 1000 mg per day. In one embodiment, the desired dose is conveniently presented in a single dose or in divided doses administered simultaneously or at appropriate intervals, for example as two, three, four or more sub-doses per day.
[00241] In one embodiment, the daily dosages appropriate for the compound described herein, or a pharmaceutically acceptable salt thereof, are from about 0.01 to about 50 mg/kg per body weight. In some embodiments, the daily dosage or the amount of active in the dosage form are lower or higher than the ranges indicated herein, based on a number of variables in regard to an individual treatment regime. In various embodiments, the daily and unit dosages are altered depending on a number of variables including, but not limited to, the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.
[00242] Toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD50 and the ED50. The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD50 and ED50. In certain embodiments, the data obtained from cell culture assays and animal studies are used in formulating the therapeutically effective daily dosage range and/or the therapeutically effective unit dosage amount for use in mammals, including humans. In some embodiments, the daily dosage amount of the compounds described herein lies within a range of circulating concentrations that include the ED50 with minimal toxicity. In certain embodiments, the daily dosage range and/or the unit dosage amount varies within this range depending upon the dosage form employed and the route of administration utilized.
[00243] In any of the aforementioned aspects are further embodiments in which the effective amount of the compound described herein, or a pharmaceutically acceptable salt thereof, is: (a) systemically administered to the mammal; and/or (b) administered orally to the mammal; and/or (c) intravenously administered to the mammal; and/or (d) administered by injection to the mammal; and/or (e) administered topically to the mammal; and/or (f) administered non- systemically or locally to the mammal.
[00244] In any of the aforementioned aspects are further embodiments comprising single administrations of the effective amount of the compound, including further embodiments in which (i) the compound is administered once a day; or (ii) the compound is administered to the mammal multiple times over the span of one day.
[00245] In any of the aforementioned aspects are further embodiments comprising multiple administrations of the effective amount of the compound, including further embodiments in which (i) the compound is administered continuously or intermittently: as in a single dose; (ii) the time between multiple administrations is every 6 hours; (iii) the compound is administered to the mammal every 8 hours; (iv) the compound is administered to the mammal every 12 hours; (v) the compound is administered to the mammal every 24 hours. In further or alternative
embodiments, the method comprises a drug holiday, wherein the administration of the compound is temporarily suspended or the dose of the compound being administered is temporarily reduced; at the end of the drug holiday, dosing of the compound is resumed. In one embodiment, the length of the drug holiday varies from 2 days to 1 year.
[00246] In certain instances, it is appropriate to administer at least one compound described herein, or a pharmaceutically acceptable salt thereof, in combination with one or more other therapeutic agents. In certain embodiments, the pharmaceutical composition further comprises one or more anti-cancer agents.
[00247] In one embodiment, the therapeutic effectiveness of one of the compounds described herein is enhanced by administration of an adjuvant (i.e., by itself the adjuvant has minimal therapeutic benefit, but in combination with another therapeutic agent, the overall therapeutic benefit to the patient is enhanced). Or, in some embodiments, the benefit experienced by a patient is increased by administering one of the compounds described herein with another agent (which also includes a therapeutic regimen) that also has therapeutic benefit.
[00248] In one specific embodiment, a compound described herein, or a pharmaceutically acceptable salt thereof, is co-administered with a second therapeutic agent, wherein the compound described herein, or a pharmaceutically acceptable salt thereof, and the second therapeutic agent modulate different aspects of the disease, disorder or condition being treated, thereby providing a greater overall benefit than administration of either therapeutic agent alone.
[00249] In any case, regardless of the disease, disorder or condition being treated, the overall benefit experienced by the patient may be additive of the two therapeutic agents or the patient may experience a synergistic benefit. [00250] In certain embodiments, different therapeutically-effective dosages of the compounds disclosed herein will be utilized in formulating pharmaceutical composition and/or in treatment regimens when the compounds disclosed herein are administered in combination with one or more additional agent, such as an additional therapeutically effective drug, an adjuvant or the like.

Example B-l: Human ASK1 ADP-Glo Assay
[00356] The ability of test compounds to inhibit ASK1 kinase activity was determined using the luminescent ADP-Glo™ Kinase Assay and Myelin Basic Protein (MBP) as a substrate (Promega Corporation, Madison, WI). During the kinase reaction, ASK1 utilizes ATP and generates ADP. The remaining ATP is then depleted by addition of the ADP-Glo™ reagent which also terminates the reaction. Subsequent addition of the Kinase Detection Reagent converts the ADP that was produced during the kinase reaction to ATP, and this newly synthesized ATP is converted to light using the luciferase/luciferin reactions. The assay was performed according to the manufacturer's instructions. Briefly, purified, recombinant ASK1 (amino acids 649-946) (10-20 ng/well) was added to a 384-well, F bottom, small volume, HIbase, white plate (Greiner Bio-One, Monroe, North Carolina #784075) containing 1-2 μΙ_, 5X test compound or vehicle control (diluted 1 :20 from a 100% DMSO stock solution into IX Reaction Buffer A). The enzyme was allowed to pre- incubate with test compound from 15-120 min at 30 °C before the addition of the ATP/substrate mix (final concentrations of 50 μΜ ATP + 250 ng MBP in IX Reaction Buffer A). The mixture was then incubated at room temperature for 40 min before the addition of of ADP-Glo™ reagent and a second 40 minute room temperature incubation. Following the addition of the Kinase Detection Reagent, the plate was incubated for an additional 40 min at room temperature before reading luminescence on a FlexStation 3 (Molecular Devices, Sunnyvale, CA). Maximum activity was determined from wells treated with vehicle and was set to 100% and minimum activity was determined from wells containing no enzyme and this was set to 0%. Percent inhibition was calculated relative to the controls and the data graphed in Collaborative Drug Discovery (CDD) Vault (Burlingame, CA).

Example B-4: Mouse LPS-induced TNFa Release Pharmacodynamic Assay.The
administration of lipopolysaccharide (LPS) induces the release of TNFa through the activation of ASK1. Mice (C56B1/6, Balb/c, C3H) are administered test compound orally, intraperitoneally, intravenously or subcutaneously 1-24 hours prior to LPS. Mice are then injected intraperitoneally with 0.3 mg/kg LPS (Salmonella typhosd) and ninety minutes later, animals are anesthetized with 3-4% isoflurane and blood collected via cardiac puncture into serum separator tubes. Blood is allowed to sit at room temperature for ~1 hour then centrifuged at 12,000 rmp for 10 minutes at 4°C to prepare serum. TNFa concentrations in serum are measured using a commercially available ELISA. Example B-5: Mouse Oropharyngeal Bleomycin Model of Lung Fibrosis
[00361] Lung fibrosis was induced in C57B1/6 male mice by administering bleomycin (0.1-4 U/kg) via oropharyngeal instillation. Mice were either pretreated with vehicle or test compound orally, intraperitoneally, intravenously or subcutaneously either prophylactically (1 day to 1 hour before bleomycin instillation) or therapeutically (7-14 days post bleomycin instillation). The route and frequency of dosing were based on previously determined pharmacokinetic properties for the inhibitors in mouse. After bleomycin instillation, animals were monitored daily for weight loss and clinical signs for 14-28 days prior to sacrifice. Animals were euthanized at study termination and weighed. Blood (for isolation of plasma) and bronchoalveolar lavage fluid were collected and frozen for subsequent analyses. Lungs were removed, weighed, then either inflated and fixed by instillation of 10% formalin and prepared for histological examination or homogenized in 1 mL PBS for collagen determination using a hydroxyproline assay. For histological examination, lung slices were stained with Masson's tri chrome or picrosirius red to measure fibrillar collagen as an indicator of fibrosis and an Ashcroft score of lung fibrosis and inflammatory damage determined. For lung hydroxyproline content, 0.5 ml of the lung homogenate is removed and added to 0.5 mL 12 N HC1 and the samples heated at 120°C overnight. After the acid hydrolysis, 25-100 μL of the supernatant is dried down, resuspended in 25 μL water and the hydroxyproline content determined by the addition of 0.5 mL Chloramine T solution (140 mg Chloramine T in 6.5 ml ddH20 + 1 ml n-propanol + 2.5 mL 1M sodium acetate) and incubation at room temperature for 20 min. After the incubation, 0.5 mL Erlich's solution (1.48 g of 4-(dimethylamino (benzaldehyde) in 7 mL n-propanol + 2.88 ml 60% perchloric acid and 0.12 mL ddH20) is added and incubated at 65°C for 15 min before reading the absorbance at 550 nm.
Example B-6: Rat/Mouse CC14 Model of Liver Fibrosis
[00362] Liver fibrosis is induced in mice (Balb/c or C57B1/6) by intraperitoneal administration of CC14 (0.5-2 ml/kg body weight) diluted in corn oil twice weekly for 4-8 weeks or by oral administration two-three times weekly using an escalating dose protocol (Popov et al. 2011 Gastroenetrology; 140(5): 1642-1652.). Liver fibrosis is induced in rats by either intraperitoneal administration (1-2.5 ml/kg) or by oral administration in oil (mineral, olive or corn) twice weekly for 6-12 weeks. Inhibitors are delivered orally, intraperitoneally, intravenously or subcutaneously 1 day to 1 hour prior to the initial CC14 dosing (prophylactic dosing) or 1-4 weeks after the initial CCI4 dosing (therapeutic dosing). At the end of the study, mice are sacrificed by opening the chest cavity under isoflurane, blood is drawn via cardiac puncture into EDTA vacutainer tubes and the liver is harvested. Part of the liver is fixed in 10% neutral buffered formalin for subsequent histopathological analysis of inflammation and fibrosis by H&E staining and
Picrosirius red staining. The remaining tissue is snap frozen at -80 °C for subseuquent hydroxyproline analysis of total collagen content.
Example B-7: Thioacetamide (TAA) model of Liver Fibrosis in mouse
[00363] Liver fibrosis is induced in Balb/c or C57B1/6 mice by intraperitoneal injection of thioacetamide (TAA) at doses ranging from 100-400 mg/kg 3x/week. Doses of TAA are either constant throughout the study period (100-200 mg/kg) or escalate from 100 mg/kg to 400 mg/kg every 2 weeks to increase tolerance to the TAA treatment. Inhibitors are administered orally, intraperitoneally, intravenously or subcutaneously given prophylactically (starting prior to TAA administration) or therapeutically (3-6 weeks after initiation of TAA administration). Liver fibrosis is studied 8-12 weeks after initiation of TAA. At the end of the study, mice are sacrificed by opening the chest cavity under isoflurane, blood is drawn via cardiac puncture into EDTA vacutainer tubes and the liver is harvested. Part of the liver is fixed in 10% neutral buffered formalin for subsequent histopathological analysis of inflammation and fibrosis by H&E staining and picrosirius red staining. Unstained histology sections are also assessed using 2 photon fluorescence and second-harmonic generation imaging. The remaining tissue is snap frozen at - 80°C for subsequent hydroxyproline analysis of total collagen content or mRNA analyses. Serum is collected for analysis of liver biochemistries (ALT, AST, ALP, and bilirubin) as a measure of liver function.
Example B-8: Mouse model of NASH induced through a choline deficient, amino-acid defined (CDAA) diet supplemented with high fat content
Liver fibrosis is induced by feeding C57B1/6 mice a choline-deficient L-amino acid-defined high- fat diet (CDAAHFD) containing 60% kcal% fat and 0.1% methionine (Research Diets C/N A06071302) starting at 6 weeks of age. Once on diet for 4-6 weeks of age, mice are screened for and those with abnormally elevated bilirubin levels are excluded. Remaining mice are assigned to groups and dosing initiated. Inhibitors are administered orally, intraperitoneally, intravenously or subcutaneously at 30-100 mg/kg/day for an additional 8-12 weeks. At the end of the study, mice are sacrificed by opening the chest cavity under isoflurane, blood is drawn via cardiac puncture into EDTA vacutainer tubes and the liver is harvested. Part of the liver is fixed in 10% neutral buffered formalin for subsequent histopathological analysis of inflammation and fibrosis by H&E, trichrome and/or Picrosirius red staining. The remaining tissue is snap frozen at -80°C for subsequent hydroxyproline analysis of total collagen content, total cholesterol, liver triglyceride and/or mRNA analyses.
