Definitions

  • the present invention relates to methods of stabilizing the alpha subunit of hypoxia inducible factor (HIF) and to compounds that can be used in these methods.
  • HIF hypoxia inducible factor
  • HIF hypoxia inducible factor
  • bHLH basic helix-loop-helix
  • PAS Per/Arnt/Sim transcriptional activator that mediates changes in gene expression in response to changes in cellular oxygen concentration.
  • HIF is a heterodimer containing an oxygen-regulated alpha subunit (HIF ⁇ ) and a constitutively expressed beta subunit (HIF ⁇ ), also known as aryl hydrocarbon receptor nuclear transporter (ARNT).
  • NNT aryl hydrocarbon receptor nuclear transporter
  • HIF ⁇ subunits are rapidly degraded by a mechanism that involves ubiquitination by the von Hippel-Lindau tumor suppressor (pVHL) E3 ligase complex.
  • pVHL von Hippel-Lindau tumor suppressor
  • HIF ⁇ is not degraded, and an active HIF ⁇ / ⁇ complex accumulates in the nucleus and activates the expression of several genes including glycolytic enzymes, glucose transporter (GLUT)-1, erythropoietin (EPO), and vascular endothelial growth factor (VEGF).
  • GLUT glucose transporter
  • EPO erythropoietin
  • VEGF vascular endothelial growth factor
  • HIF ⁇ protein levels are elevated in most cells in response to hypoxia and HIF ⁇ is induced in vivo when animals are subjected to anemia or hypoxia. HIF ⁇ levels rise within a few hours after the onset of hypoxia and return to baseline under continued hypoxic conditions. HIF has been implicated in numerous cellular and developmental processes including cell proliferation, angiogenesis, and cell cycle arrest. HIF ⁇ has also been associated with myocardial acute ischemia and early infarction, pulmonary hypertension, and inflammation. Although HIF ⁇ has been associated with tumor growth and metastasis, there is little indication that HIF is directly involved in tumorigenesis.
  • hypoxic preconditioning in which a target organ is subjected to brief periods of hypoxia, has been shown to protect both myocardium and brain against hypoxic-ischemic injury.
  • HIF ⁇ stabilization is closely associated with ischemia and is induced by preconditioning.
  • HIF ⁇ levels are increased by a number of factors that mimic hypoxia, including iron chelators such as desferrioxamine (DFO) and divalent metal salts such as CoCl 2 HIF ⁇ levels are increased by angiotensin II, thrombin, and platelet-derived growth factor under normoxic conditions using a mechanism involving reactive oxygen species. Reports have also suggested HIF ⁇ is regulated by phosphorylation through pathways involving nitric oxide-activated phosphotidylinositol 3′-kinase (PI3K), hepatocyte growth factor, or mitogen-activated protein kinase.
  • PI3K nitric oxide-activated phosphotidylinositol 3′-kinase
  • hepatocyte growth factor or mitogen-activated protein kinase.
  • Glycogen-synthase kinase which is a downstream target of PI3K, directly phosphorylates the HIF ⁇ ODD domain.
  • hypoxia a state of reduced oxygen, can occur when the lungs are compromised or blood flow is reduced.
  • Ischemia reduction in blood flow, can be caused by the obstruction of an artery or vein by a blood clot (thrombus) or by any foreign circulating matter (embolus), or by a vascular disorder such as atherosclerosis.
  • Reduction in blood flow can have a sudden onset and short duration (acute ischemia), or can have a slow onset with long duration or frequent recurrence (chronic ischemia).
  • Acute ischemia is often associated with regional, irreversible tissue necrosis (an infarct), whereas chronic ischemia is usually associated with transient hypoxic tissue injury.
  • Infarctions commonly occur in the spleen, kidney, lungs, brain, and heart, producing disorders such as intestinal infarction, pulmonary infarction, ischemic stroke, and myocardial infarction.
  • Pathologic changes in ischemic disorders depend on the duration and severity of ischemia, and on the length of patient survival. Necrosis can be seen within the infarct in the first 24 hours, and an acute inflammatory response develops in the viable tissue adjacent to the infarct with leukocytes migrating into the area of dead tissue. Over succeeding days, there is a gradual breakdown and removal of cells within the infarct by phagocytosis, and replacement with a collagenous or glial scar.
  • hypoperfusion or infarction in one organ often affects other organs.
  • ischemia of the lung caused by, for example, a pulmonary embolism, not only affects the lung, but also puts the heart and other organs, such as the brain, under hypoxic stress.
  • Myocardial infarction which often involves coronary artery blockage due to thrombosis, arterial wall vasospasms, or viral infection of the heart, can lead to congestive heart failure and systemic hypotension. Secondary complications such as global ischemic encephalopathy can develop if the cardiac arrest is prolonged with continued hypoperfusion.
  • Cerebral ischemia most commonly caused by vascular occlusion due to atherosclerosis, can range in severity from transient ischemic attacks (TIAs) to cerebral infarction or stroke. While the symptoms of TIAs are temporary and reversible, TIAs tend to recur and are often followed by a stroke.
  • TIAs transient ischemic attacks
  • Occlusive arterial disease includes coronary artery disease, which can lead to myocardial infarction, and peripheral arterial disease, which can affect the abdominal aorta, its major branches, and arteries of the legs.
  • Peripheral arterial disease includes Buerger's disease, Raynaud's disease, and acrocyanosis.
  • peripheral arterial disease is commonly caused by atherosclerosis, other major causes include, e.g., diabetes, etc.
  • Complications associated with peripheral arterial disease include severe leg cramps, angina, abnormal heart rhythms, heart failure, heart attack, stroke, and kidney failure.
  • Cardiovascular diseases cause at least 15 million deaths every year and are responsible for 30% of deaths worldwide.
  • ischemic heart disease and cerebrovascular diseases cause approximately 17% of deaths.
  • 1.3 million cases of nonfatal acute myocardial infarction are reported, making the prevalence approximately 600 per 100,000 people.
  • an estimated five million Americans suffer from venous thrombosis every year, and approximately 600,000 of these cases result in pulmonary embolism.
  • About one-third of the pulmonary embolisms end in death, making pulmonary embolism the third most common cause of death in the United States.

  • FIELD OF THE INVENTION
  • The present invention relates to methods of stabilizing the alpha subunit of hypoxia inducible factor (HIF) and to compounds that can be used in these methods.
  • BACKGROUND OF THE INVENTION
  • An early response to tissue hypoxia is induction of hypoxia inducible factor (HIF), a basic helix-loop-helix (bHLH) PAS (Per/Arnt/Sim) transcriptional activator that mediates changes in gene expression in response to changes in cellular oxygen concentration. HIF is a heterodimer containing an oxygen-regulated alpha subunit (HIFα) and a constitutively expressed beta subunit (HIFβ), also known as aryl hydrocarbon receptor nuclear transporter (ARNT). In oxygenated (normoxic) cells, HIFα subunits are rapidly degraded by a mechanism that involves ubiquitination by the von Hippel-Lindau tumor suppressor (pVHL) E3 ligase complex. Under hypoxic conditions, HIFα is not degraded, and an active HIFα/β complex accumulates in the nucleus and activates the expression of several genes including glycolytic enzymes, glucose transporter (GLUT)-1, erythropoietin (EPO), and vascular endothelial growth factor (VEGF). (Jiang et al. (1996) J Biol Chem 271:17771-17778; Iliopoulus et al. (1996) Proc Natl Acad Sci USA 93:10595-10599; Maxwell et al. (1999) Nature 399:271-275; Sutter et al. (2000) Proc Natl Acad Sci USA 97:4748-4753; Cockman et al. (2000) J Biol Chem 275:25733-25741; and Tanimoto et al. (2000) EMBO J. 19:4298-4309.)
  • Levels of HIFα protein are elevated in most cells in response to hypoxia and HIFα is induced in vivo when animals are subjected to anemia or hypoxia. HIFα levels rise within a few hours after the onset of hypoxia and return to baseline under continued hypoxic conditions. HIF has been implicated in numerous cellular and developmental processes including cell proliferation, angiogenesis, and cell cycle arrest. HIFα has also been associated with myocardial acute ischemia and early infarction, pulmonary hypertension, and inflammation. Although HIFα has been associated with tumor growth and metastasis, there is little indication that HIF is directly involved in tumorigenesis. Hypoxic preconditioning, in which a target organ is subjected to brief periods of hypoxia, has been shown to protect both myocardium and brain against hypoxic-ischemic injury. HIFα stabilization is closely associated with ischemia and is induced by preconditioning. (Wang and Semenza (1993) Proc Natl Acad Sci USA 90:4304-4308; Stroka et al. (2001) FASEB J 15:2445-2453; Semenza et al. (1997) Kidney Int 51:553-555; Carmeliet et al. (1998) Nature 394:485-490; Zhong et al. (1999) Cancer Res 59:5830-5835; Lee et al.

(2000) Biochem J 350:307-312; Deindl and Schaper (1998) Mol Cell Biochem 186:43-51; Bergeron et al. (2000) Ann Neurol 48:285-296.)
  • Several investigators have studied the mechanism of interaction between HIFα and pVHL. An oxygen-dependent degradation domain (ODD) within HIF-1α from residue 401 to 603 was originally identified as sufficient to confer oxygen-dependent instability to chimeric protein constructs. A domain containing a portion of the ODD, from residue 526 to 652, was found to be required for pVHL-dependent degradation. Further, mutation of P564YI to aspartic acids or mutation of K532 to arginine within a region conserved among HIFα homologs (residue 556 to 574 in HIF-1α) rendered the full-length HIFα protein stable under normoxic conditions and resistant to pVHL-mediated degradation. (Huang et al. (1998) Proc Natl Acad Sci USA 95:7987-7992; and Tanimoto et al. (2000) EMBO J. 19:4298-4309.)
  • HIFα levels are increased by a number of factors that mimic hypoxia, including iron chelators such as desferrioxamine (DFO) and divalent metal salts such as CoCl2 HIFα levels are increased by angiotensin II, thrombin, and platelet-derived growth factor under normoxic conditions using a mechanism involving reactive oxygen species. Reports have also suggested HIFα is regulated by phosphorylation through pathways involving nitric oxide-activated phosphotidylinositol 3′-kinase (PI3K), hepatocyte growth factor, or mitogen-activated protein kinase. Glycogen-synthase kinase, which is a downstream target of PI3K, directly phosphorylates the HIFα ODD domain. (Richard et al. (2000) J Biol Chem 275:26765-26771; Sandau et al. (2000) Biochem Biophys Res Commun 278:263-267; Tacchini et al. (2001) Carcinogenesis 22:1363-1371; and Sodhi et al. (2001) Biochem Biophys Res Commun 287:292-300.)
  • Hypoxia, a state of reduced oxygen, can occur when the lungs are compromised or blood flow is reduced. Ischemia, reduction in blood flow, can be caused by the obstruction of an artery or vein by a blood clot (thrombus) or by any foreign circulating matter (embolus), or by a vascular disorder such as atherosclerosis. Reduction in blood flow can have a sudden onset and short duration (acute ischemia), or can have a slow onset with long duration or frequent recurrence (chronic ischemia). Acute ischemia is often associated with regional, irreversible tissue necrosis (an infarct), whereas chronic ischemia is usually associated with transient hypoxic tissue injury. If the decrease in perfusion is prolonged or severe, however, chronic ischemia can also be associated with an infarct. Infarctions commonly occur in the spleen, kidney, lungs, brain, and heart, producing disorders such as intestinal infarction, pulmonary infarction, ischemic stroke, and myocardial infarction.
  • Pathologic changes in ischemic disorders depend on the duration and severity of ischemia, and on the length of patient survival. Necrosis can be seen within the infarct in the first 24 hours, and an acute inflammatory response develops in the viable tissue adjacent to the infarct with leukocytes migrating into the area of dead tissue. Over succeeding days, there is a gradual breakdown and removal of cells within the infarct by phagocytosis, and replacement with a collagenous or glial scar.
  • Hypoperfusion or infarction in one organ often affects other organs. For example, ischemia of the lung, caused by, for example, a pulmonary embolism, not only affects the lung, but also puts the heart and other organs, such as the brain, under hypoxic stress. Myocardial infarction, which often involves coronary artery blockage due to thrombosis, arterial wall vasospasms, or viral infection of the heart, can lead to congestive heart failure and systemic hypotension. Secondary complications such as global ischemic encephalopathy can develop if the cardiac arrest is prolonged with continued hypoperfusion. Cerebral ischemia, most commonly caused by vascular occlusion due to atherosclerosis, can range in severity from transient ischemic attacks (TIAs) to cerebral infarction or stroke. While the symptoms of TIAs are temporary and reversible, TIAs tend to recur and are often followed by a stroke.
  • Occlusive arterial disease includes coronary artery disease, which can lead to myocardial infarction, and peripheral arterial disease, which can affect the abdominal aorta, its major branches, and arteries of the legs. Peripheral arterial disease includes Buerger's disease, Raynaud's disease, and acrocyanosis. Although peripheral arterial disease is commonly caused by atherosclerosis, other major causes include, e.g., diabetes, etc. Complications associated with peripheral arterial disease include severe leg cramps, angina, abnormal heart rhythms, heart failure, heart attack, stroke, and kidney failure.
  • Ischemic and hypoxic disorders are a major cause of morbidity and mortality. Cardiovascular diseases cause at least 15 million deaths every year and are responsible for 30% of deaths worldwide. Among the various cardiovascular diseases, ischemic heart disease and cerebrovascular diseases cause approximately 17% of deaths. Annually, 1.3 million cases of nonfatal acute myocardial infarction are reported, making the prevalence approximately 600 per 100,000 people. Further, an estimated five million Americans suffer from venous thrombosis every year, and approximately 600,000 of these cases result in pulmonary embolism. About one-third of the pulmonary embolisms end in death, making pulmonary embolism the third most common cause of death in the United States.
  • Currently, treatment of ischemic and hypoxic disorders is focused on relief of symptoms and treatment of causative disorders. For example, treatments for myocardial infarction include nitroglycerin and analgesics to control pain and relieve the workload of the heart. Other medications, including digoxin, diuretics, amrinone, β-blockers, lipid-lowering agents and angiotensin-converting enzyme inhibitors, are used to stabilize the condition, but none of these therapies directly address the tissue damage produced by the ischemia and hypoxia.
  • Due to deficiencies in current treatments, there remains a need for methods that are effective in treating conditions involving ischemia and hypoxia such as occlusive arterial disease, angina pectoris, intestinal infarctions, pulmonary infarctions, cerebral ischemia, and myocardial infarction. There is also a need for methods that are effective in the prevention of tissue damage caused by ischemia that occurs due to, e.g., atherosclerosis, diabetes, and pulmonary disorders such as pulmonary embolism and the like. In summary, there is a need in the art for methods and compounds that can be used to stabilize HIF, and to treat and prevent HIF-associated disorders including conditions involving ischemia and hypoxia.

Such events can include, for example, surgery, e.g., angioplasty, organ transplantation, etc., and related procedures such as administration of anesthesia, etc. Furthermore, chronic events specific embodiments, the methods of pretreating or preconditioning are applied in situations where a subject has a disorder predictive of the development of a HIF-associated condition, e.g., transient ischemic attack or angina pectoris, indicative of stroke and myocardial infarction, respectively, in order to prevent the development of or reduce the degree of development of the HIF-associated condition. In a particular embodiment, a compound that stabilizes HIFα is administered to a subject in order to increase preconditioning factors for ischemia, for example, EPO, etc.
  • Methods for increasing expression of various HIF-related factors are specifically contemplated herein. In one aspect, the present invention provides a method for increasing expression of angiogenic factors in a subject, the method comprising stabilizing HIFα. In another aspect, the present invention provides a method of increasing expression of glycolytic factors in a subject, the method comprising stabilizing HIFα. In a further aspect, the invention provides a method of increasing expression of factors associated with oxidative stress in a subject, the method comprising stabilizing HIFα. A method of treating a subject having a disorder associated with ischemic reperfusion injury, the method comprising stabilizing HIFα, is also contemplated.
  • Methods for identifying compounds that stabilize HIFα are also provided herein. For example, the present invention provides a method of identifying a compound that stabilizes HIFα, the method comprising: (a) administering a compound of interest to a subject or to a sample from a subject; (b) measuring the HIFα level in the subject or in the sample; and (c) comparing the HIFα level in the subject or in the sample to a standard level, wherein an increase in the HIFα level in the subject or the sample is indicative of a compound that stabilizes HIFα.
  • In another aspect, the methods of the invention are used to prevent the tissue damage caused by HIF-associated disorders including, but not limited to, ischemic and hypoxic disorders. In one embodiment, treatment is predicated on predisposing conditions, e.g., hypertension, diabetes, occlusive arterial disease, chronic venous insufficiency, Raynaud's disease, cirrhosis, congestive heart failure, and systemic sclerosis.
  • In yet another aspect, the methods of the invention can be used as a pretreatment to decrease or prevent the tissue damage caused by HIF-associated disorders including, but not limited to, ischemic and hypoxic disorders. In one embodiment, the need for pretreatment is based on a patient's history of recurring episodes of an ischemic condition, e.g., myocardial infarction or transient ischemic attacks, or has symptoms of impending ischemia, e.g., angina pectoris, etc. In another embodiment, the need for pretreatment is based on physical parameters implicating possible or likely ischemia or hypoxia, such as is the case with, e.g., individuals placed under general anesthesia or temporarily working at high altitudes. In yet another embodiment, the methods may be used in the context of organ transplants to pretreat organ donors and to maintain organs removed from the body prior to implantation in a recipient.
  • In another aspect, the invention provides compounds that stabilize HIFα and methods of using the compounds to prevent, pretreat, or treat HIF-associated conditions such as those described above. In one embodiment, a therapeutically effective amount of the compound or a pharmaceutically acceptable salt thereof, alone or in combination with a pharmaceutically acceptable excipient, is administered to a subject having a HIF-associated condition. In one specific embodiment, the compound is administered immediately following the diagnosis of an acute ischemic disorder. In another specific embodiment, the compound is administered to a subject during the course of a chronic ischemic condition. In yet another specific embodiment, the ischemia is due to a transient or acute trauma, insult, or injury such as, e.g., a spinal cord injury. In a specific embodiment, the compound is administered to a patient in need following diagnosis of a pulmonary disorder such as COPD and the like.
  • In one aspect, the compound can be administered based on predisposing conditions, e.g., chronic conditions, or as a pretreatment to decrease or prevent tissue damage caused by HIF-associated disorders. In a specific aspect, the compound is administered to a subject who has a history of recurring episodes of an ischemic condition, e.g., myocardial infarction or transient ischemic attacks, or has symptoms of impending ischemia, e.g., angina pectoris. In another specific embodiment, the compound is administered based on physical parameters implicating possible ischemia or hypoxia, such as is the case with, e.g., individuals placed under general anesthesia or temporarily working at high altitudes. In yet another embodiment, the compounds may be used in the context of organ transplants to pretreat organ donors and to maintain organs removed from the body prior to implantation in a recipient.
  • In one aspect, a compound of the present invention stabilizes HIFα by specifically inhibiting hydroxylation of amino acid residues in the HIFα protein. In one embodiment, the agent inhibits hydroxylation of HIFα proline residues. In one specific embodiment, the agent inhibits hydroxylation of the HIF-1α P564 residue or a homologous proline in another HIFα isoform. In another specific embodiment, the agent inhibits hydroxylation of the HIF-1α P402 residue or a homologous proline in another HIFα isoform. In yet another embodiment, the compound may additionally inhibit hydroxylation of HIFα asparagine residues. In one specific embodiment, the agent inhibits hydroxylation of the HIF-1α N803 residue or a homologous asparagine residue in another HIFα isoform.
  • In certain embodiments, compounds used in the methods of the invention are selected from a compound of the formula (I)

  • Definitions
  • The term “ischemia” refers to a reduction in blood flow. Ischemia is associated with a reduction in nutrients, including oxygen, delivered to tissues. Ischemia may arise due to conditions such as atherosclerosis, formation of a thrombus in an artery or vein, or blockage of an artery or vein by an embolus, vascular closure due to other causes, e.g., vascular spasm, etc. Such conditions may reduce blood flow, producing a state of hypoperfusion to an organ or tissue, or block blood flow completely. Other conditions that can produce ischemia include tissue damage due to trauma or injury, such as, e.g., spinal cord injury; viral infection, which can lead to, e.g., congestive heart failure, etc. The terms “ischemic conditions” and “ischemic disorders” refer to acute ischemic conditions including, but not limited to, myocardial infarction, ischemic stroke, pulmonary embolism, perinatal hypoxia, circulatory shock including, e.g., hemorrhagic, septic, cardiogenic, etc., mountain sickness, acute respiratory failure, etc., chronic ischemic conditions including atherosclerosis, chronic venous insufficiency, chronic heart failure, cardiac cirrhosis, diabetes, macular degeneration, sleep apnea, Raynaud's disease, systemic sclerosis, nonbacterial thrombotic endocarditis, occlusive artery disease, angina pectoris, TIAs, chronic alcoholic liver disease, etc. Ischemic conditions may also result when individuals are placed under general anesthesia, and can cause tissue damage in organs prepared for transplant.
  • The terms “hypoxia” and “hypoxic” refer to an environment with levels of oxygen below normal. Hypoxia may be induced in cells by culturing the cells in a reduced oxygen environment, or cells may be treated with compounds that mimic hypoxia. Determining oxygen levels that define hypoxia in cell culture is well within the skill in the art.
  • The terms “hypoxic conditions” and “hypoxic disorders” include, but are not limited to, ischemic disorders (ischemic hypoxia) such as those listed above, wherein hypoxia results from reduced circulation; pulmonary disorders (hypoxic hypoxia) such as COPD, severe pneumonia, pulmonary edema, pulmonary hypertension, hyaline membrane disease, and the like, wherein hypoxia results from reduced oxygenation of the blood in the lungs; anemic disorders (anemic hypoxia) such as gastric or duodenal ulcers, liver or renal disease, thrombocytopenia or blood coagulation disorders, cancer or other chronic illness, cancer chemotherapy and other therapeutic interventions that produce anemia, and the like, wherein hypoxia results from a decreased concentration of hemoglobin or red blood cells; and altitude sickness, etc.
  • The terms “disorders” and “diseases” are used inclusively and refer to any condition deviating from normal. The terms “ischemic conditions” and “ischemic disorders” refer to any condition, disease, or disorder that is associated with ischemia.

Immunogenic fragments or antigenic fragments are fragments of polypeptides, preferably, fragments of about five to fifteen amino acids in length, that retain at least one biological or immunological activity. Where “amino acid sequence” is used to refer to the polypeptide sequence of a naturally occurring protein molecule, “amino acid sequence” and like terms are not meant to limit the amino acid sequence to the complete native sequence associated with the recited protein molecule.
  • The term “related proteins” as used herein, for example, to refer to proteins related to HIFα prolyl hydroxylase, encompasses other 2-oxoglutarate dioxygenase enzymes, especially those family members that similarly require Fe2+, 2-oxoglutarate, and oxygen to maintain hydroxylase activity. Such enzymes include, but are not limited to, e.g., procollagen lysyl hydroxylase, procollagen prolyl 4-hydroxylase, and Factor Inhibiting HIF (FIH), an asparaginyl hydroxylase responsible for regulating transactivation of HIFα.

  • Invention
  • The present invention provides methods of stabilizing HIFα, to compounds that can be used in the methods, and to the use of the methods to prevent or treat disorders associated with HIF including, but not limited to, hypoxic and/or ischemic disorders such as those described above. The present invention further relates to the discovery that stabilization of the alpha subunit of hypoxia inducible factor (HIFα) is an effective therapeutic approach with unexpected benefits when applied to treatment or prevention of conditions associated with hypoxia and/or ischemia, e.g., myocardial infarction, stroke, occlusive arterial disease, angina pectoris, cardiac cirrhosis, atherosclerosis, etc.
  • The present invention contemplates methods of stabilizing HIF to augment angiogenesis, the response to acute hypoxia, and adaptation to chronic hypoxia. As tissue ischemia is a major cause of morbidity and mortality, the identification of methods that stabilize HIFα is beneficial in the treatment of hypoxic conditions. Further, the methods can be used to produce the beneficial effects of, e.g., a preconditioning hypoxic response, by stabilizing HIFα in a normoxic environment prior to an ischemic or hypoxic event. The methods can also be used to induce HIFα-specific effects, as described below, including therapeutic angiogenesis to restore blood flow to damaged tissues; neuroprotection to prevent, e.g., apoptotic loss of neurons associated with neurodegenerative diseases; and protection against oxidative damage produced by reactive oxygen species resulting from, e.g., reperfusion following an ischemic or hypoxic event.
  • When the methods of the invention are used to treat a disorder associated with ischemia and/or hypoxia, the disorder may be an acute ischemic disorder such as pulmonary, intestinal, cerebral, and/or myocardial infarction, or a chronic ischemic condition such as occlusive arterial disease, liver cirrhosis, congestive heart failure, etc. Further, the methods of the invention can be used to treat ischemia due to a transient or acute trauma, insult, or injury such as, e.g., a spinal cord injury, or to treat a patient diagnosed with, e.g., a pulmonary disorder such as pulmonary embolism and the like.
  • When the methods of the invention are used to prevent tissue damage caused by HIF-associated disorders including, but not limited to, ischemic and hypoxic disorders, treatment may be predicated on predisposing conditions, e.g., hypertension, diabetes, occlusive arterial disease, chronic venous insufficiency, Raynaud's disease, systemic sclerosis, cirrhosis, congestive heart failure, etc. Similarly, the methods of the invention can be used as a pretreatment to decrease or prevent the tissue damage caused by HIF-associated disorders including, but not limited to, ischemic and hypoxic disorders. The need for pretreatment may be based on a patient's history of recurring episodes of an ischemic condition, e.g., myocardial infarction or transient ischemic attacks; based on symptoms of impending ischemia, e.g., angina pectoris; or based on physical parameters implicating possible or likely ischemia or hypoxia, such as is the case with, e.g., individuals placed under general anesthesia or temporarily working at high altitudes. The methods may also be used in the context of organ transplants to pretreat organ donors and to maintain organs removed from the body prior to implantation in a recipient.
  • Presented herein is the discovery that stabilization of HIFα is modulated by proline hydroxylation and that HIFα stabilization is effective for treating or preventing the development or persistence of ischemic conditions such as DVT, angina pectoris, pulmonary embolism, stroke, myocardial infarction, etc. Specifically, it has been shown that HIF-1α and a HIF-1α peptide corresponding to residues 556 to 575 [HIF(556-575)] preincubated with rabbit reticulocyte lysate (RRL) bind specifically to the von Hippel Lindau protein (pVHL), and that such binding leads to the ubiquitination and degradation of HIF-1α. It has also been shown that mutation of the highly conserved colinear sequence M561LAPYIPM within HIF(556-575) to eight consecutive alanines stabilized HIF(556-575) under normoxic conditions. (Srinivas et al., supra.) An alanine scan of the region showed that mutation of P564 to alanine in the context of full-length HIF-1α or a glutathione S-transferase (GST)-HIFα oxygen degradation domain (ODD) fusion protein (Gal4-ODD) abrogated pVHL-binding activity. The modification of P564 was identified as an hydroxylation by electrospray ion trap tandem mass spectrometry (MS/MS), and by thin layer chromatography of Gal-4-HIF(555-575) that was in vitro translated using RRL in the presence of [3H]proline. The functional significance of the proline hydroxylation was demonstrated by showing that P564-hydroxylated HIFα bound pVHL, while HIF-1α mutant containing a single point mutation of P564 to alanine was stable in COS7 cells and was insensitive to the hypoxia mimetic desferrioxamine. (See Ivan and Kaelin, supra; Jaakkola et al. (2001) Science 292:468-472.)
  • As HIFα is modified by proline hydroxylation, a reaction requiring oxygen and Fe2+, the present invention contemplates in one aspect that the enzyme responsible for HIFα hydroxylation is a member of the 2-oxoglutarate dioxygenase family. Such enzymes include, but are not limited to, procollagen lysyl hydroxylase, procollagen prolyl 3-hydroxylase, procollagen prolyl 4-hydroxylase α(I) and α(II), thymine 7-hydroxylase, aspartyl (asparaginyl) β-hydroxylase, ε-N-trimethyllysine hydroxylase, and γ-butyrobetaine hydroxylase, etc. These enzymes require oxygen, Fe2+, 2-oxoglutarate, and ascorbic acid for their hydroxylase activity. (See, e.g., Majamaa et al. (1985) Biochem J 229:127-133; Myllyharju and Kivirikko (1997) EMBO J 16:1173-1180; Thornburg et al. (1993) 32:14023-14033; and Jia et al. (1994) Proc Natl Acad Sci USA 91:7227-7231.)
  • Several small molecule inhibitors of prolyl 4-hydroxylase have been identified. (See, e.g., Majamaa et al., supra; Kivirikko and Myllyharju (1998) Matrix Biol 16:357-368; Bickel et al. (1998) Hepatology 28:404-411; Friedman et al. (2000) Proc Natl Acad Sci USA 97:4736-4741; and Franklin et al. (2001) Biochem J 353:333-338; all incorporated by reference herein in their entirety.) The present invention contemplates the use of these compounds in the methods provided herein.
  • Compounds that can be used in the methods of the invention include, for example, structural mimetics of 2-oxoglutarate. Such compounds may inhibit the target 2-oxoglutarate dioxygenase enzyme family member competitively with respect to 2-oxoglutarate and noncompetitively with respect to iron. (Majamaa et al. (1984) Eur J Biochem 138:239-245; and Majamaa et al., supra.)

  • Based on the common mechanism of action of the 2-oxoglutarate dioxygenase family members, such as dependence on Fe2+ and 2-oxoglutarate for activity, in certain aspects the invention is directed to use of compounds, including the compounds described herein, to inhibit HIFα hydroxylation and thus stabilize HIFα in an oxygen-independent manner. Further, the examples and figures of the present invention demonstrate that application of such compounds stabilize HIFα and subsequently induce HIF-regulated gene products in vitro and in vivo. In specific embodiments, these compounds are used to produce a specific benefit in the prevention and treatment of ischemic and hypoxic conditions.
  • The methods of the present invention stabilize HIFα in a dose-dependent manner in cells grown in a normoxic environment. Although different cell types show different levels of HIFα in the presence of a compound of the invention, all of the cell lines tested showed some level of HIFα stabilization. The level of HIFα in untreated cells is usually low to undetectable.
  • Stabilization of HIFα leads to HIF-dependent gene expression in vitro and in vivo, including genes encoding angiogenic factors such as VEGF, Flt-1, EG-VEGF, PAI-1, adrenomedullin, and Cyr61. Thus, the ability to stabilize HIFα has potential benefits in the induction of angiogenesis and prevention of tissue damage due to ischemia and hypoxia. For example, transgenic mice expressing constitutively active HIF-1α in the epidermis show enhanced expression of each VEGF isoform and a significant increase in dermal capillaries. Unlike overexpression of one VEGF isoform alone, the hypervascularity induced by HIFα shows no edema, inflammation, or vascular leakage. (See, Elson et al. (2001) Genes Dev 15:2520-2532; Detmar et al. (1998) J Invest Derm 111:1-6; Larcher et al. (1998) Oncogene 17:303-311; and Thurston et al. (1999) Science 286:2511-2514.) Therefore, in certain aspects, methods of the invention can be used to induce therapeutic angiogenesis, which involves the development of collateral blood vessels to revascularize ischemic tissues.
  • Additionally, the methods of the invention produce a dose-dependent decrease in oxygen consumption in cells without any affect on cell viability. Stable HIF complexes activate expression of proteins involved in glucose uptake and utilization, such as glucose transporter (GluT)-1 and GluT-3; aldolase-A, enolase-1, hexokinase-1 and -2, and phosphofructokinase-L and -C. The reduction in oxygen consumption associated with HIF stabilization is potentially due to a shift in cellular metabolism from aerobic to anaerobic energy production. The present methods can thus be applied to generate energy under low oxygen conditions, beneficial in ischemic and hypoxic conditions such as, for example, peripheral arterial disease, DVT, angina pectoris, pulmonary embolism, stroke, and myocardial infarction. Methods of increasing glucose uptake and utilization by cells of the body, generally applicable to the treatment of other conditions, e.g., diabetes, are also provided.
  • The invention further provides methods for increasing oxygen-carrying capacity by inducing erythropoiesis, and facilitating iron transport and utilization. Specifically, methods of the invention increase expression of erythropoietin (EPO), a naturally occurring hormone that stimulates the production of red blood cells. (See, e.g., commonly owned, copending U.S. Patent Application Publication No. 2003/0153503, incorporated herein by reference in its entirety.) Methods for increasing expression of enzymes and proteins involved in iron uptake, transport, and processing are specifically contemplated. Such enzymes and proteins include, but are not limited to, transferrin and transferrin receptor, which together facilitate iron transport to and uptake by, e.g., erythroid tissue; and ceruloplasmin, a ferroxidase required to oxidize ferrous iron to ferric iron. As transferrin can only bind and transport ferric iron, ceruloplasmin is important for supply of iron to tissues. The ability of the methods of the invention to increase both endogenous erythropoietin and transport and utilization of iron provides specific advantage in oxygen delivery in both normoxic and hypoxic environments.
  • In one aspect, the invention includes methods that provide neuroprotective benefits, e.g., by stabilizing HIF. For example, both VEGF and EPO have been shown to be neuroprotective. (See, e.g., Jin et al. (2000) Proc Natl Acad Sci USA. 97:10242-10247; Bocker-Meffert et al. (2002) Invest Ophthalmol Vis Sci 43:2021-2026; Buemi et al. (2002) Clin Sci (Lond) 103:275-282; and Siren et al. (2001) Proc Natl Acad Sci USA 98:4044-4049.) EPO also facilitates recovery from spinal cord injuries and provides neuroprotective benefits when induced prior to an ischemic event. (See, e.g., Gorio et al. (2002) Proc Natl Acad Sci USA 99:9450-9455; and Dawson (2002) Lancet 359:96-97.) As the methods of the invention increase expression of neuroprotective factors such as VEGF and EPO, the methods provide neuroprotective benefit that can be applied to treatment, pretreatment, or prevention of conditions including, e.g., diabetic neuropathy, stroke, neurodegenerative disease, trauma, injury, e.g., concussions, spinal cord injuries, etc., or prior to surgical procedures, e.g., wherein cerebral ischemic reperfusion injury may result.
  • Hypoxic preconditioning has been shown to effectively protect against subsequent acute ischemic insult. As the primary effect of hypoxia is stabilization of HIFα and subsequent activation of HIF-regulated genes, the methods of the invention will mimic hypoxic preconditioning in a normoxic environment. For example, the methods may be used prior to surgery, wherein ischemic-reperfusion injury may be expected to produce deleterious results in the patient. Such preventive therapy, when applied prior to an ischemic event, can be provided at any time point prior to the event, in a single or repeated dose format.
  • The methods of the invention also coordinately upregulate genes involved in oxidative stress and vascular tone. Such genes include, e.g., inducible nitric oxide synthase (iNOS), and heme oxygenase 1. Production of iNOS has also been associated with the beneficial effects of hypoxic preconditioning in several animal models. (See, e.g., Serracino-Inglott et al. (2002) BMC Gastroenterol 2:22-27; Kuntscher et al. (2002) Br J Plast Surg 55:430-433.) Significantly, blocking iNOS activity attenuates but does not abrogate the beneficial effects of preconditioning, whereas nonspecifically blocking protein production completely abrogates the benefits of preconditioning. (Wang et al. (2002) Cardiovasc Res 56:33-42.) This suggests that iNOS is an important component of the physiological response to preconditioning, but is not the only factor. As the methods of the invention coordinately regulate various factors, including iNOS, involved in hypoxic response, the methods of the invention will more accurately replicate the beneficial effects of hypoxic preconditioning.
  • Methods of Using the Compounds of the Invention
  • The present invention provides methods of inhibiting HIFα hydroxylation, thereby stabilizing HIF and activating HIF-regulated gene expression. The methods can be applied to the prevention, pretreatment, or treatment of conditions associated with HIF including ischemic and hypoxic conditions. Such conditions include, for example, myocardial infarction, liver ischemia, renal ischemia, and stroke; peripheral vascular disorders, ulcers, burns, and chronic wounds; pulmonary embolism; and ischemic-reperfusion injury, including, for example, ischemic-reperfusion injury associated with surgery and organ transplantation. In one embodiment, the present invention provides methods of stabilizing HIFα before, during, or immediately after ischemia or hypoxia, particularly in association with myocardial infarction, stroke, or renal ischemic-reperfusion injury.
  • In one aspect, the invention provides methods for treating various ischemic and hypoxic conditions, in particular, using the compounds described herein. In one embodiment, the methods of the invention produce therapeutic benefit when administered following ischemia or hypoxia. For example, the methods of the invention produce a dramatic decrease in morbidity and mortality following myocardial infarction, and a significant improvement in heart architecture and performance. Further, the methods of the invention improve liver function when administered following hepatic toxic-ischemic injury. Hypoxia is a significant component of liver disease, especially in chronic liver disease associated with hepatotoxic compounds such as ethanol. Additionally, expression of genes known to be induced by HIFα, e.g., nitric oxide synthase and glucose transporter-1, is increased in alcoholic liver disease. (See, e.g., Areel et al. (1997) Hepatology 25:920-926; Strubelt (1984) Fundam Appl Toxicol 4:144-151; Sato (1983) Pharmacol Biochem Behav 18 (Suppl 1):443-447; Nanji et al. (1995) Am J Pathol 146:329-334; and Morio et al. (2001) Toxicol Appl Pharmacol 172:44-51.)
  • Therefore, the present invention provides methods of treating conditions associated with ischemia or hypoxia, the method comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof, alone or in combination with a pharmaceutically acceptable excipient, to a subject. In one embodiment, the compound is administered immediately following a condition producing acute ischemia, e.g., myocardial infarction, pulmonary embolism, intestinal infarction, ischemic stroke, and renal ischemic-reperfusion injury. In another embodiment, the compound is administered to a patient diagnosed with a condition associated with the development of chronic ischemia, e.g., cardiac cirrhosis, macular degeneration, pulmonary embolism, acute respiratory failure, neonatal respiratory distress syndrome, and congestive heart failure. In yet another embodiment, the compound is administered immediately after a trauma or injury.
  • In another aspect, the invention provides methods for treating a patient at risk of developing an ischemic or hypoxic condition, e.g., individuals at high risk for atherosclerosis, etc., using the compounds described herein. Risk factors for atherosclerosis include, e.g., hyperlipidemia, cigarette smoking, hypertension, diabetes mellitus, hyperinsulinemia, and abdominal obesity. Therefore, the present invention provides methods of preventing ischemic tissue injury, the method comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof, alone or in combination with a pharmaceutically acceptable excipient, to a patient in need. In one embodiment, the compound can be administered based on predisposing conditions, e.g., hypertension, diabetes, occlusive arterial disease, chronic venous insufficiency, Raynaud's disease, chronic skin ulcers, cirrhosis, congestive heart failure, and systemic sclerosis.
  • In one specific embodiment, the methods are used to increase vascularization and/or granulation tissue formation in damaged tissue, wounds, and ulcers. For example, compounds of the invention have been shown to be effective in stimulating granulation tissue formation in wound healing. Granulation tissue contains newly formed, leaky blood vessels and a provisional stroma of plasma proteins, such as fibrinogen and plasma fibronectin. Release of growth factors from inflammatory cells, platelets, and activated endothelium, stimulates fibroblast and endothelial cell migration and proliferation within the granulation tissue. Ulceration can occur if vascularization or neuronal stimulation is impaired. The methods of the invention are effective at promoting granulation tissue formation. Thus, the invention provides methods for treating a patient having tissue damage due to, e.g., an infarct, having wounds induced by, e.g., trauma or injury, or having chronic wounds or ulcers produced as a consequence of a disorder, e.g., diabetes. The method comprises administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof, alone or in combination with a pharmaceutically acceptable excipient, to a patient in need.
  • In another aspect, the invention provides methods of using the compounds to pretreat a subject to decrease or prevent the development of tissue damage associated with ischemia or hypoxia. The methods of the invention produce therapeutic benefit when administered immediately before a condition involving ischemia or hypoxia. For example, application of the methods of the invention prior to induction of myocardial infarction shows statistically significant improvement in heart architecture and performance. Further, the methods of the invention produce therapeutic benefit when administered immediately before and during ischemic-reperfusion injury, significantly reducing diagnostic parameters associated with renal failure.
  • Therefore, the invention provides methods of pretreating a subject to decrease or prevent the tissue damage associated with ischemia or hypoxia, the method comprising administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof, alone or in combination with a pharmaceutically acceptable excipient, to a patient with a history of ischemic disorders, e.g., myocardial infarctions, or having symptoms of impending ischemia, e.g., angina pectoris. In another embodiment, the compound can be administered based on physical parameters implicating possible ischemia, e.g., individuals placed under general anesthesia or temporarily working at high altitudes. In yet another embodiment, the compounds may be used in organ transplants to pretreat organ donors and to maintain organs removed from the body prior to implantation in the recipient.
  • Previous studies have shown that certain compounds used in the methods of the present invention are effective inhibitors of procollagen prolyl 4-hydroxylase. While it is recognized that recovery from an initial infarct or wound requires connective tissue deposition within the necrotic region, the present invention demonstrates no adverse affects of treatment with respect to scar formation. Thus, based on the benefits provided by certain compounds of the invention on treatment and prevention of hypoxic tissue damage and fibrosis, the present invention contemplates a “dual-therapy” approach to treatment or prevention of conditions involving ischemia or hypoxia, including ischemia or hypoxia associated with subsequent reactive fibrosis, e.g., myocardial infarction and resultant congestive heart failure. The method may use one compound that inhibits more than one 2-oxoglutarate dioxygenase enzyme, e.g., HIF prolyl hydroxylase and procollagen prolyl 4-hydroxylase, with either the same specificity or with different specificities. Alternatively, the method may use a combination of compounds wherein each compound specifically inhibits only one 2-oxoglutarate dioxygenase enzyme, e.g., one compound specifically inhibits HIF prolyl hydroxylase and a second compound specifically inhibits procollagen prolyl 4-hydroxylase.
  • In one aspect, a compound of the invention inhibits one or more 2-oxoglutarate dioxygenase enzymes. In one embodiment, the compound inhibits at least two 2-oxoglutarate dioxygenase family members, e.g., HIF prolyl hydroxylase and HIF asparagine-hydroxylase (FIH-1), with either the same specificity or with differential specificity. In another embodiment, the compound is specific for one 2-oxoglutarate dioxygenase, e.g., HIF prolyl hydroxylase, and shows little to no specificity for other family members.
  • The compounds can be administered in combination with various other therapeutic approaches. In one embodiment, the compound is administered with another 2-oxoglutarate dioxygenase inhibitor, wherein the two compounds have differential specificity for individual 2-oxoglutarate dioxygenase family members. The two compounds may be administered at the same time as a ratio of one relative to the other. Determination of a ratio appropriate to a given course of treatment or a particular subject is within the level of skill in the art. Alternatively, the two compounds may be administered consecutively during a treatment time course, e.g., following myocardial infarction. In a particular embodiment, one compound specifically inhibits HIF prolyl hydroxylase enzyme activity, and a second compound specifically inhibits procollagen prolyl 4-hydroxylase enzyme activity. In another specific embodiment, one compound specifically inhibits HIF prolyl hydroxylase enzyme activity, and a second compound specifically inhibits HIF asparaginyl-hydroxylase enzyme activity. In another embodiment, the compound is administered with another therapeutic agent having a different mode of action, e.g., an ACE inhibitor (ACEI), angiotensin-II receptor blocker (ARB), statin, diuretic, digoxin, camitine, etc.
  • Pharmaceutical Formulations and Routes of Administration
  • The compositions of the present invention can be delivered directly or in pharmaceutical compositions along with suitable carriers or excipients, as is well known in the art. Present methods of treatment can comprise administration of an effective amount of a compound of the invention to a subject having or at risk for an ischemic condition, e.g., congestive heart failure, atherosclerosis, etc. In a preferred embodiment, the subject is a mammalian subject, and in a most preferred embodiment, the subject is a human subject. Preferred routes of administration include oral and transdermal delivery mechanisms.
  • 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 and selection of an appropriate formulation is within the level of skill in the art. (See, e.g., Gennaro, ed. (1995) Remingon's Pharmaceutical Sciences, supra; and Hardman, Limbird, and Gilman, eds. (2001) The Pharmacological Basis of Therapeutics, supra.)
  • Suitable routes of administration may, for example, include oral, rectal, transmucosal, nasal, or intestinal administration and parenteral delivery, including intramuscular, subcutaneous, intramedullary injections, as well as intrathecal, direct intraventricular, intravenous, intraperitoneal, intranasal, or intraocular injections. The agent or composition thereof may be administered in a local rather than a systemic manner. For example, a suitable agent can be delivered via injection or in a targeted drug delivery system, such as a depot or sustained release formulation.
  • The pharmaceutical compositions of the present invention may be manufactured by any of the methods well-known in the art, such as by conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilizing processes. As noted above, the compositions of the present invention can include one or more physiologically acceptable carriers such as excipients and auxiliaries that facilitate processing of active molecules into preparations for pharmaceutical use.
  • Proper formulation is dependent upon the route of administration chosen. For injection, for example, the composition may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks's solution, Ringer's solution, or physiological saline buffer. For transmucosal or nasal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. For oral administration, the compounds can be formulated readily by combining the active compounds with pharmaceutically acceptable carriers well known in the art. Such carriers enable the compounds of the invention to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for oral ingestion by a subject. The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.
  • Pharmaceutical preparations for oral use can be obtained as solid excipients, optionally grinding a resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose, and/or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate.
  • 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.
  • Pharmaceutical preparations for oral administration include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. 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 addition, stabilizers may be added.
  • In one embodiment, the compounds of the present invention can be administered transdermally, such as through a skin patch, or topically. In one aspect, the transdermal or topical formulations of the present invention can additionally comprise one or multiple penetration enhancers or other effectors, including agents that enhance migration of the delivered compound. Transdermal or topical administration could be preferred, for example, in situations in which location specific delivery is desired.
  • For administration by inhalation, the compounds for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide, or any other suitable gas. In the case of a pressurized aerosol, the appropriate dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, for example, gelatin, for use in an inhaler or insufflator may be formulated. These typically contain a powder mix of the compound and a suitable powder base such as lactose or starch.
  • Compositions formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion, can 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. Formulations for parenteral administration include aqueous solutions or other compositions in water-soluble form.
  • Suspensions of the active compounds may also be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil and synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances that increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents that increase the solubility of the compounds to allow for the preparation of highly concentrated solutions. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.
  • As mentioned above, the compositions of the present invention may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example, subcutaneous or intramuscular) or by intramuscular injection. Thus, for example, the present 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.
  • Suitable carriers for the hydrophobic molecules of the invention are well-known in the art and include co-solvent systems comprising, for example, benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. The co-solvent system may be the VPD co-solvent system. VPD is a solution of 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant polysorbate 80, and 65% w/v polyethylene glycol 300, made up to volume in absolute ethanol. The VPD co-solvent system (VPD:5W) consists of VPD diluted 1:1 with a 5% dextrose in water solution. This co-solvent system is effective in dissolving hydrophobic compounds and produces low toxicity upon systemic administration. Naturally, the proportions of a co-solvent system may be varied considerably without destroying its solubility and toxicity characteristics. Furthermore, the identity of the co-solvent components may be varied. For example, other low-toxicity nonpolar surfactants may be used instead of polysorbate 80, the fraction size of polyethylene glycol may be varied, other biocompatible polymers may replace polyethylene glycol, e.g., polyvinyl pyrrolidone, and other sugars or polysaccharides may substitute for dextrose.
  • Alternatively, other delivery systems for hydrophobic molecules may be employed. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. Liposomal delivery systems are discussed above in the context of gene-delivery systems. Certain organic solvents such as dimethylsulfoxide also may be employed, although usually at the cost of greater toxicity. Additionally, the compounds may be delivered using sustained-release systems, such as semi-permeable matrices of solid hydrophobic polymers containing the effective amount of the composition to be administered. Various sustained-release materials are established and available to those of skill in the art. Sustained-release capsules may, depending on their chemical nature, release the compounds for a few weeks up to over 100 days. Depending on the chemical nature and the biological stability of the therapeutic reagent, additional strategies for protein stabilization may be employed.
  • For any composition used in the present methods of treatment, a therapeutically effective dose can be estimated initially using a variety of techniques well known in the art. For example, based on information obtained from a cell culture assay, a dose can be formulated in animal models to achieve a circulating concentration range that includes the IC50. Similarly, dosage ranges appropriate for human subjects can be determined, for example, using data obtained from cell culture assays and other animal studies.
  • A therapeutically effective dose of an agent refers to that amount of the agent 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 the therapeutic index, which can be expressed as the ratio LD50, ED50. Agents that exhibit high therapeutic indices are preferred.
  • Dosages preferably 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 the route of administration utilized. The exact formulation, route of administration, and dosage 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 modulate HIFα stabilization and H1F-regulated gene induction, as desired, i.e., minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from, for example, in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics of the compound and the route of administration. Agents or compositions thereof should be administered using a regimen which maintains plasma levels above the MEC for about 10-90% of the duration of treatment, preferably about 30-90% of the duration of treatment, and most preferably between 50-90%. 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 will, of course, 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 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. The pack or dispenser device may be accompanied by instructions for administration. Compositions comprising a compound of the invention formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition. Suitable conditions indicated on the label may include treatment of disorders or diseases in which ischemia or hypoxia is a major indication.
  • Compound Screening and Identification
  • The present invention further provides methods of screening for and identifying additional compounds that inhibit HIFα hydroxylation, or that stabilize HIFα, etc.
  • Various assays and screening techniques, including those described below, can be used to identify small molecules that modulate (e.g., increase or decrease) the level or activity of HIFα. Assays will typically provide for detectable signals associated with the consumption of a reaction substrate or production of a reaction product. Detection can involve, for example, fluorophores, radioactive isotopes, enzyme conjugates, and other detectable labels well known in the art. The results may be qualitative or quantitative. Isolation of the reaction product may be facilitated by a label, such as biotin or a histidine tag that allows purification from other reaction components via precipitation or affinity chromatography.
  • Assays for HIFα hydroxylation may involve measuring hydroxylated proline or lysine residues in HIFα or a fragment thereof (see, e.g., Palmerini et al. (1985) J Chromatogr 339:285-292), or measuring formation of succinate from 2-oxoglutarate in the presence of enzyme and HIFα or a fragment thereof (see, e.g., Cunliffe et al. (1986) Biochem J 240:617-619). Exemplary procedures that measure HIFα hydroxylation are described in Ivan et al. (supra) and Example 10. An exemplary procedure that measures production of succinate from 2-oxoglutarate is described by Kaule and Gunzler. (1990; Anal Biochem 184:291-297.) Substrate molecules may include HIFα or a fragment thereof, e.g., HIF(556-575); for example, an exemplary substrate for use in the assay described in Example 10 is [methoxycoumarin]-DLDLEALAPYIPADDDFQL-amide (SEQ ID NO:5). Enzyme may include, e.g., HIFα prolyl hydroxylase (see, e.g., GenBank Accession No. AAG33965, etc.), obtained from any source. Enzyme may also be present in a crude cell lysate or in a partially purified form. Compounds that stabilize HIFα or that inhibit hydroxylation of HIFα may be identified by measuring and comparing enzyme activity in the absence and presence of the compound.
  • Additionally and in combination with the above methods, compounds can be identified by any of a variety of screening techniques known in the art. Such screening methods may allow for target polypeptides or the compounds to be free in solution, affixed to a solid support, borne on a cell surface, or located within a cell. For example, test compounds may be arrayed on a surface and analyzed for activity in a manner analogous to array methods currently available in the art. (See, e.g., Shalon et al. (1995) International Publication No. WO 95/35505; Baldeschweiler et al. (1995) International Publication No. WO 95/251116; Brennan et al. (1995) U.S. Pat. No. 5,474,796; and Heller et al. (1997) U.S. Pat. No. 5,605,662.)
  • These and other embodiments of the present invention will readily occur to those of ordinary skill in the art in view of the disclosure herein, and are specifically contemplated.
  • EXAMPLES
  • The invention is understood by reference to the following examples, which are intended to be purely exemplary of the invention. The present invention is not limited in scope by the exemplified embodiments, which are intended as illustrations of single aspects of the invention only. Any methods that are functionally equivalent are within the scope of the invention. Various modifications of the invention in addition to those described herein will become apparent to those skilled in the art from the foregoing description and accompanying figures. Such modifications fall within the scope of the appended claims.
  • Example 1 HIFα Stabilization in Cells In Vitro
  • Human cells derived from adenovirus-transformed fetal kidney epithelium (293A), cervical epithelial adenocarcinoma (HeLa), hepatocellular carcinoma (Hep3B), foreskin fibroblast (HFF), mammary gland epithelial adenocarcinoma (MCF7), umbilical vein endothelium (HUVEC), microvascular endothelium (HMEC-1), squamous carcinoma (SSC-25), lung fibroblast (HLF), and venous endothelium (AG10774B) tissues (see, e.g., American Type Culture Collection, Manassas Va.; and Qbiogene, Carlsbad Calif.) were separately seeded into 35 mm culture dishes and grown at 37° C., 20% O2, 5% CO2 in media as follows: HeLa cells in Dulbecco's Modification of Eagle's Medium (DMEM), 2% fetal bovine serum (FBS); HFF and HLF cells in DMEM, 10% FBS; 293A cells in DMEM, 5% FBS; HUVEC and AG10774B cells in Endothelial Growth Media (EGM-2; BioWhittaker, Inc., Walkersville Md.); and HMEC-1 in RPMI 1640, 10% FBS; and Hep3B cells in Minimal Essential Medium (MEM), Earle's BSS (Mediatech Inc., Herndon Va.), 2 mM L-glutamine, 0.1 mM non-essential amino acids, 1 mM sodium pyruvate, 10% FBS. When cell layers reached confluence, the media was replaced with OPTI-MEM media (Invitrogen Life Technologies, Carlsbad Calif.) and cell layers were incubated for approximately 24 hours in 20% O2, 5% CO2 at 37° C. Compound of the invention (one of compounds A to 0) or DMSO (0.5 to 1%) was then added to existing medium, and incubation was continued overnight.
  • Following incubation, the media was removed, centrifuged, and stored for analysis (see below). The cells were washed two times in cold phosphate buffered saline (PBS) and then lysed in 1 ml of 10 mM Tris (pH 7.4), 1 mM EDTA, 150 mM NaCl, 0.5% IGEPAL (Sigma-Aldrich, St. Louis Mo.), and a protease inhibitor mix (Roche Molecular Biochemicals) for 15 minutes on ice. Cell lysates were centrifuged at 3,000×g for 5 minutes at 4° C., and the cytosolic fractions (supernatant) were collected. The nuclei (pellet) were resuspended and lysed in 100 μl of 20 mM HEPES (pH 7.2), 400 mM NaCl, 1 mM EDTA, 1 mM dithiothreitol, and a protease mix (Roche Molecular Biochemicals), centrifuged at 13,000×g for 5 minutes at 4° C., and the nuclear protein fractions (supernatant) were collected.
  • Nuclear fractions were normalized based on protein concentration and loaded onto a 4-12% TG gel and fractionated under reducing conditions. Proteins were transferred to a PVDF membrane (Invitrogen Corp., Carlsbad Calif.) at 500 mA for 1.5 hours. The membrane was blocked in T-TBS, 2% milk for 1 hour at room temperature and incubated overnight with mouse anti-human HIF-1α antibody (BD Biosciences, Bedford Mass.), diluted 1:250 in T-TBS, 2% milk. The blot was developed using SUPERSIGNAL WEST chemiluminescent substrate (Pierce, Rockford Ill.). As can be seen in FIG. 1A, various compounds of the invention (Compounds A to F) stabilized HIFα in a normoxic environment in a dose-dependent manner, allowing HIFα to accumulate within the cell. As seen in FIG. 1B, various cell types, including fibroblasts, epithelial cells, endothelial cells, and hepatocytes from various sources, showed dose-dependent stabilization of HIFα when treated with a compound of the invention in a normoxic environment.
  • Alternatively, nuclear and cytosolic fractions as prepared above were analyzed for HIF-1α using a QUANTIKINE immunoassay (R&D Systems, Inc., Minneapolis Minn.) according to the manufacturer's instructions. As shown in FIG. 2A, epithelial cells (293A) and hepatocytes (Hep3B) treated with various compounds of the invention (Compounds B and G to 0) showed stabilization and accumulation of HIFα as compared to vehicle-treated control cells. As shown in FIG. 2B, cells treated with compounds of the invention showed dose-dependent stabilization of HIFα.
  • Example 2 Effect on Oxygen Consumption
  • Oxygen Sensor cell culture plates (BD Biosciences, Bedford Mass.) contain a ruthenium complex which is more fluorescent in the absence of oxygen. Therefore, the fluorescent read-out is increased by the presence of oxygen-consuming cells in the plate, which change the equilibrium to lower oxygen saturation and higher fluorescence. A compound that stabilizes HIF by inhibiting hydroxylation is expected to decrease oxygen consumption by decreasing oxygen consumed by the hydroxylation event itself and/or by shifting cellular metabolism from aerobic to anaerobic energy production.
  • Human cells derived from adenovirus-transformed fetal kidney epithelium (293A) or cervical epithelial adenocarcinoma (HeLa) (American Type Culture Collection) were grown to confluence in media (high glucose DMEM (Mediatech, Inc., Herndon Va.), 1% penicillin/streptomycin mixture (Mediatech), 1% fetal bovine serum) at 37° C., 10% CO2. Cells were collected and resuspended in media at a density of 500,000 cells/ml. The cell suspension was distributed at 0.2 ml/well into each well of an Oxygen Biosensor 96-well cell culture plate (BD Biosciences). The following treatments were added in 10 μl volumes to triplicate sets of wells: (1) 0.5% DMSO; (2) 200 μM sodium dodecyl sulfate; or (3) 1, 10, or 50 μM compound (one of compounds B, G, or a prodrug of compound V [pV]).
  • Cultures were incubated at 37° C., 10% CO2 for 72 hours and plates were then read in an FL600 flourimeter (Biotek Instruments, Inc., Winooski Vt.) at an excitation wavelength of 485 nm and emission wavelength of 590 nm. Data was plotted as a function of fold change relative to DMSO control (O2 consumption) or absorbance at a wavelength of 450 nm (WST-1) and descriptive statistical analysis was performed using EXCEL software (Microsoft Corporation, Bellevue Wash.).
  • FIG. 3A shows the fold change in oxygen consumtion in cells treated with compound relative to control cells. As can be seen in the figure, all of the compounds produced a decrease in oxygen consumtion to some degree. Further, the reduction in oxygen consumption was dose-dependent (FIG. 3A), and even at the highest doses little to no loss of cell viability was detected (FIG. 1B). Additional experiments (not shown) in various cell culture test systems, including incorporation of 3H-thymidine and total incorporation of amino acids, confirmed that the decrease in oxygen consumption was not associated with cytotoxicity.
  • Example 3 Expression of HIF-Regulated Genes In Vitro
  • Conditioned media collected from cell cultures grown as in Example 1 was analyzed for vascular endothelial growth factor (VEGF) expression using a QUANTIKINE immunoassay (R&D Systems) according to the manufacturer's instructions. As seen in FIG. 4A, fibroblasts (HFF), epithelial cells (293A), and hepatocytes (Hep3B) treated with various compounds of the invention (one of compounds A, B, C, H, K, L, Q, and a prodrug of compound V [pV]) showed an increase in VEGF expression (FIG. 4A). Values on the y-axis represent fold-induction relative to control and are reported on a log2 scale, such that a value of 1 represents 2-fold induction.
  • Alternatively, human cells derived from adenovirus-transformed fetal kidney epithelium (293A) were cultured in DMEM, 5% FBS, 1% Penicillin-Streptomycin at 37° C. and 10% CO2. After 48 hours, the cells were harvested and were plated confluent in 35 mm culture dishes in regular culture media, and after 1 day the media was changed to Opti-Mem I. After 18 to 24 hours, compound B was added to the media and incubation was continued for an additional 18 hours. Culture supernatant was then removed, the plates were placed on ice, lysis buffer (LB)-1 was added and the cells were harvested by scraping. The scraped cells were collected and incubated for 15 minutes on ice followed by centrifugation at 3000 g for 5 minutes at 4° C. The supernatant, which represents the cytosolic fraction, was collected and cytosolic proteins were separated under denaturing and reducing conditions using SDS polyacrylamide gels that were loaded with equal amounts of protein per lane.
  • Gel electrophoresis was conducted at 150 V for 2 hours, and after SDS-PAGE the proteins were transferred to a PVDF membrane for 1.5 hours at 400 mA at 4° C. The membrane was then incubated in blocking buffer, washed once with T-TBS, and then anti-aldolase antibody diluted to working concentration in blocking buffer was added and the blots were incubated over night with gentle agitation at 4° C. The membrane was then washed 4 times with T-TBS, followed by incubation for one hour at room temperature with blocking buffer containing labeled secondary antibody. The membrane was then washed four times with T-TBS. The antigen specific for the primary antibody was visualized by exposing X-ray-film and developed using the ECL SUPERSIGNAL WEST FEMTO or PICO chemiluminescent substrate (Pierce, Rockford Ill.) according to the manufacturer's instructions.
  • FIG. 4B shows that the compound increased expression of aldolase, an enzyme involved in glycolysis, over time. Thus, stabilization of HIFα by compounds of the invention leads to subsequent increase in expression of HIF-regulated genes.
  • Example 4 HIFα Stabilization in Cells In Vivo
  • Swiss Webster male mice (30-32 g) are obtained, e.g., from Charles River Laboratories, Inc. (Wilmington Mass.), or Simonsen, Inc. (Gilroy, Calif.), and treated by oral gavage one or more times per day for at least one day with a 2 ml/kg volume of either 0.5% carboxymethyl cellulose (CMC; Sigma-Aldrich) (control) or 5.0% compound (0.5% CMC). At one or more time points after the final dose, e.g., two and five hours, animals are anesthetized with isoflurane and 0.1 ml blood is collected, e.g., from the orbital sinus into a heparinized tube. After all selected time points have been reached, animals are subjected to a sub-lethal dose of CO2 and blood is collected from the abdominal vein into a heparinized tube. All blood samples are stored at −80° C.
  • Tissues isolated from animals treated with compounds of the invention as described above are analyzed for HIFα protein levels as follows. Tissues are homogenized in 3 ml of 10 mM Tris (pH 7.4), 1 mM EDTA, 150 mM NaCl, 0.5% IGEPAL (Sigma-Aldrich), and a protease inhibitor mix (Roche Molecular Biochemicals) for 15 seconds using a POLYTRON PT-1200 homogenizer (Brinkmann Instruments, Inc., Westbury N.Y.). Cell lysates are centrifuged at 3,000×g for 5 minutes at 4° C., and the cytosolic fraction (supernatant) is collected. The nuclei (pellet) are resuspended and lysed in 100 μl of 20 mM HEPES (pH 7.2), 400 mM NaCl, 1 mM EDTA, 1 mM dithiothreitol, and a protease mix (Roche Molecular Biochemicals), centrifuged at 13,000×g for 5 minutes at 4° C., and the nuclear protein fraction (supernatant) is collected.
  • Nuclear fractions are normalized based on protein concentration and loaded onto a 4 to 12% TG gel and fractionated under reducing conditions. Proteins are transferred to a PVDF membrane (Invitrogen Life Technologies) at 500 mA for 1.5 hours. The membrane is blocked in T-TBS, 2% milk for 1 hour at room temperature and incubated overnight with anti-HIFα antibody diluted in T-TBS, 2% milk. The blot is developed using SUPERSIGNAL WEST PICO chemiluminescent substrate (Pierce, Rockford Ill.).
  • Alternatively, nuclear and cytosolic fractions as prepared above are analyzed for HIF-1α using a QUANTIKINE immunoassay (R&D Systems) according to the manufacturer's instructions.
  • Example 5 Expression of HIF-Regulated Genes In Vivo
  • Experiment I
  • Twenty four Swiss Webster male mice (30-32 g) were obtained from Simonsen, Inc., and treated by oral gavage with a 4 ml/kg volume of either 0.5% CMC (Sigma-Aldrich) (0 mg/kg/day) or 1.25% Compound A (25 mg/ml in 0.5% CMC) (100 mg/kg). At 4, 8, 16, 24, 48, or 72 hours after the final dose, animals were anesthetized with isoflurane and a blood sample was collected from the abdominal vein. The blood sample was collected into a MICROTAINER serum separator tube (Becton-Dickinson, Franklin Lakes N.J.), incubated at room temperature for 30 minutes, centrifuged at 8,000 rpm at 4° C. for 10 min, and cell pellet was resuspended in RNALATER solution (Ambion) and stored at −80° C. The mice were then sacrificed and tissue samples of kidney, liver, brain, lung, and heart were isolated and stored in RNALATER solution (Ambion) at −80° C.
  • RNA isolation was carried out using the following protocol. A 50 mg section of each organ was diced, 875 μl of RLT buffer (RNEASY kit; Qiagen Inc., Valencia Calif.) was added, and the pieces were homogenized for about 20 seconds using a rotor-stator POLYTRON homogenizer (Kinematica, Inc., Cincinnati Ohio). The homogenate was micro-centrifuged for 3 minutes to pellet insoluble material, the supernatant was transferred to a new tube and RNA was isolated using an RNEASY kit (Qiagen) according to the manufacturer's instructions. The RNA was eluted into 80 μL of water and quantitated with RIBOGREEN reagent (Molecular Probes, Eugene Oreg.). Genomic DNA was then removed from the RNA using a DNA-FREE kit (Ambion Inc., Austin Tex.) according to the manufacturer's instructions. The absorbance at 260 and 280 nm was measured to determine RNA purity and concentration.
  • Alternatively, tissue samples were diced and homogenized in TRIZOL reagent (Invitrogen Life Technologies, Carlsbad Calif.) using a rotor-stator POLYTRON homogenizer (Kinematica). Homogenates were brought to room temperature, 0.2 volumes chloroform was added, and samples were mixed vigorously. Mixtures were incubated at room termperature for several minutes and then were centrifuged at 12,000 g for 15 min at 4° C. The aqueous phase was collected and 0.5 volumes of isopropanol were added. Samples were mixed, incubated at room temperature for 10 minutes, and centrifuged for 10 min at 12,000 g at 4° C. The supernatant was removed and the pellet was washed with 75% EtOH and centrifuged at 7,500 g for 5 min at 4° C. Genomic DNA was then removed from the RNA using a DNA-FREE kit (Ambion Inc., Austin Tex.) according to the manufacturer's instructions. The absorbance at 260 and 280 nm was measured to determine RNA purity and concentration.
  • RNA was precipitated in 0.3 M sodium acetate (pH 5.2), 50 ng/ml glycogen, and 2.5 volumes of ethanol for one hour at −20° C. Samples were centrifuged and pellets were washed with cold 80% ethanol, dried, and resuspend in water. Double stranded cDNA was synthesized using a T7-(dT)24 first strand primer (Affymetrix, Inc., Santa Clara Calif.) and the SUPERSCRIPT CHOICE system (Invitrogen) according to the manufacturer's instructions. The final cDNA was extracted with an equal volume of 25:24:1 phenol:chloroform:isoamyl alcohol using a PHASE LOCK GEL insert (Brinkman, Inc., Westbury N.Y.). The aqueous phase was collected and cDNA was precipitated using 0.5 volumes of 7.5 M ammonium acetate and 2.5 volumes of ethanol. Alternatively, cDNA was purified using the GENECHIP sample cleanup module (Affymetrix) according to the manufacturer's instructions.
  • Biotin-labeled cRNA was synthesized from the cDNA in an in vitro translation (IVT) reaction using a BIOARRAY HighYield RNA transcript labeling kit (Enzo Diagnostics, Inc., Farmingdale N.Y.) according to the manufacturer's instructions. Final labeled product was purified and fragmented using the GENECHIP sample cleanup module (Affymetrix) according to the manufacturer's instructions.
  • Hybridization cocktail was prepared by bringing 5 μg probe to 100 μl in 1× hybridization buffer (100 mM MES, 1 M [Na+], 20 mM EDTA, 0.01% Tween 20), 100 μg/ml herring sperm DNA, 500 μg/ml acetylated BSA, 0.03 nM contol oligo B2 (Affymetrix), and 1× GENECHIP eukaryotic hybridization control (Affymetrix). The cocktail was sequentially incubated at 99° C. for 5 minutes and 45° C. for 5 minutes, and then centrifuged for 5 minutes. The Murine genome U74AV2 array (MG-U74Av2; Affymetrix) was brought to room temperature and then prehybridized with 1× hybridization buffer at 45° C. for 10 minutes with rotation. The buffer was then replaced with 80 μl hybridization cocktail and the array was hybridized for 16 hours at 45° C. at 60 rpm with counter balance. Following hybridization, arrays were washed once with 6×SSPE, 0.1% Tween 20, and then washed and stained using R-phycoerythrin-conjugated streptavidin (Molecular Probes, Eugene Oreg.), goat anti-streptavidin antibody (Vector Laboratories, Burlingame Calif.), and a GENECHIP Fluidics Station 400 instrument (Affymetrix) according to the manufacturer's micro1v1 protocol (Affymetrix). Arrays were analyzed using a GENEARRAY scanner (Affymetrix) and Microarray Suite software (Affymetrix).
  • The Murine Genome U74AV2 array (Affymetrix) represents all sequences (˜6,000) in Mouse UniGene database build 74 (National Center for Biotechnology Information, Bethesda Md.) that have been functionally characterized and approximately 6,000 unannotated expressed sequence tag (EST) clusters.
  • As seen in FIG. 5A, expression of genes encoding angiogenic proteins was increased in a coordinated fashion after treatment with a compound of the invention in lung, a representative organ. Transcript patterns represented in the figure include VEGF-C, Flt-1/VEGF receptor-1, adrenomedullin, endothelin-1, plasminogen activator inhibitor (PAI)-1, and Cyr61. In the time course, mRNA levels peak early, then return to control levels after 24 hours. FIG. 5B shows the specific expression time course for two genes, endothelin-1 and adrenomedullin, representative of the cluster of genes shown in FIG. 5A. In similar experiments, a significant increase was also seen for additional HIF-regulated genes including, e.g., phosphofructokinase, enolase 1, lactate dehydrogenase, glucose transporter 1, acyl CoA thioesterase, heme oxygenase, transferrin receptor, IGFBP-1, nip3, nix, and cyclin G3.
  • As can be seen in FIG. 7A, expression of genes encoding glycolytic enzymes was increased in a coordinated fashion after treatment with a compound of the invention in kidney, a representative organ. Transcript patterns represented in the figure include aldolase-A, enolase-1, glucose transporters (GluT)-1 and -3, GAPDH, hexokinase-1 and -2, lactate dehydrogenase-A, phosphofructokinase-L and -C, phosphoglycerate kinase-1, and pyruvate kinase-M. In the time course, mRNA levels peak early, then return to control levels after 24 hours.

  • Experiment II
  • Twelve Swiss Webster male mice (30-32 g) were obtained from Simonsen, Inc., and treated by oral gavage two times per day for 2.5 days (5 doses) with a 4 ml/kg volume of either 0.5% CMC (Sigma-Aldrich) (0 mg/kg/day) or 2.5% compound (B or E; 25 mg/ml in 0.5% CMC) (200 mg/kg/day). Four hours after the final dose, animals were anesthetized with isoflurane and a blood sample was collected from the abdominal vein. The blood sample was collected into a MICROTAINER serum separator tube (Becton-Dickinson), incubated at room temperature for 30 minutes, centrifuged at 8,000 rpm at 4° C. for 10 min, and then the serum fraction was processed and analyzed for vascular endothelial growth factor (VEGF) expression using a QUANTIKINE immunoassay (R&D Systems) according to the manufacturer's instructions. The mice were then sacrificed and approximately 150 mg of liver and each kidney were isolated and stored in RNALATER solution (Ambion) at −20° C.
  • RNA isolation was carried out using the following protocol. Tissue slices were cut into small pieces, 1.75 ml of RLT lysis buffer (RNEASY kit; Qiagen) was added, and the pieces were homogenized for about 20 seconds using a rotor-stator POLYTRON homogenizer (Kinematica, Inc., Cincinnati Ohio). A 350 μl volume of homogenate was micro-centrifuged for 3 minutes to pellet insoluble material, the supernatant was transferred to a new tube and RNA was isolated using an RNEASY kit (Qiagen) according to the manufacturer's instructions. The RNA was eluted into 80 μL of water and quantitated with RIBOGREEN reagent (Molecular Probes, Eugene Oreg.). Genomic DNA was then removed from the RNA using a DNA-FREE kit (Ambion) according to the manufacturer's instructions. The absorbance at 260 and 280 nm was measured to determine RNA purity and concentration.
  • cDNA synthesis was performed using 1 μM random hexamer primers, 1 μg of total RNA, and OMNISCRIPT reverse transcriptase (Qiagen), according to the manufacturer's instructions. Resulting cDNA was diluted 5-fold with water to give 100 μL final volume. Analysis of the relative level of vascular endothelial growth factor (VEGF) gene expression was performed by quantitative PCR using a FASTSTART DNA MASTER SYBR GREEN I kit (Roche Molecular Biochemicals) and VEGF-specific primers, using a LIGHTCYCLER system (Roche Molecular Biochemicals), according to manufacturer's instructions. Samples were heated to 94° C. for 6 minutes and then cycled through 95° C. for 15 seconds, 60° C. for 5 seconds, and 72° C. for 10 seconds for a total of 42 cycles. VEGF-specific primers were as follows:
    m-VEGF-F1 GTTGCAAGGCGAGGCAGCTT (SEQ ID NO:1)
    m-VEGF-R1 TGACGATGATGGCATGGTGGT (SEQ ID NO:2)
  • The relative level of 18S ribosomal RNA gene expression was measured as a control. Quantitative PCR was performed using a QUANTITECT SYBR GREEN PCR kit (Qiagen) and 18S rRNA-specific primers, using a LIGHTCYCLER system (Roche Molecular Biochemicals), according to manufacturer's instructions. Samples were heated to 95° C. for 15 minutes and then cycled through 94° C. for 15 seconds, 60° C. for 20 seconds, 72° C. for 10 seconds for a total of 42 cycles. Ribosomal RNA-specific primers were as follows:
    18S-rat-2B TAGGCACGGCGACTACCATCGA (SEQ ID NO:3)
    18S-rat-2A CGGCGGCTTTGGTGACTCTAGAT (SEQ ID NO:4)
  • Each PCR run included a standard curve and water blank. In addition, a melt curve was run after completion of each PCR run to assess the specificity of the amplification. VEGF gene expression was normalized relative to the expression level of 18S ribosomal RNA for that sample.
  • FIG. 6A shows compound E increased VEGF expression in kidney and compound B increased VEGF expression in liver and kidney. As can be seen in FIG. 6B, levels of VEGF in the plasma of animals treated with compound are significantly increased relative to untreated control animals at 2, 5, and 20 hours after the final dose.
  • Example 6 Cardiac Ischemia
  • Experiment I
  • Nwogu et al. (2001; Circulation 104:2216-2221) reported the use of a compound of the invention following myocardial infarction. Although the authors interpreted their results relative to the compounds affect on fibrosis, the present invention clearly shows that the primary benefit on heart performance is due to stabilization of HIFα. Experiments are as described in Nwogu et al. (supra) and as described below.
  • Seventy adult male Wistar rats (200-250 g) were anaesthetized and subjected to left coronary artery occlusion to produce acute myocardial infarction (AMI). Nine animals were subjected to identical surgery without coronary artery ligation. Twenty-four to forty-eight hours after surgery, electrocardiogram (ECG) electrodes were applied to the paws and a 15 MHz linear probe (Acuson Corp., Mountain View Calif.) was applied to the chest to obtain short axis transthoracic echocardiography (2DE) images at the mid-papillary muscle level. The probe was moved cephalad or caudad and angulated until clear endocardial visualization of the left ventricular cavity was detected. Images were obtained using the Sequoia ultrasound system (Acuson). Animals with less than 20% fractional shortening and regional wall motion abnormality on the 2DE were randomized to treatment with compound A (n=14) or vehicle (n=12). The sham controls were also randomized to treatment with compound A (n=4) or vehicle (n=5).
  • Animals were treated by gavage 2 times per day for the duration of the experiment with compound A at 50 mg/kg or with vehicle alone. Serum level of drug was determined periodically to establish that treated animals received sufficient and consistent amount of drug and that the measured levels were sufficient to inhibit prolyl 4-hydroxylase, a representative 2-oxoglutarate dioxygenase.
  • Serial 2DE images were obtained weekly. Three short axis 2DE digital clips containing 5 or more systolic and diastolic frames were captured and stored. Two observers blinded to treatment did measurements off-line. For the measurements, the digital images were slowed and frozen at end systole and end diastole. Two systolic and two diastolic frames from each of the three digital clips were measured by consensus and averaged. The anterior wall in systole (AWS) and diastole (AWD), posterior wall in systole (PWS) and diastole (PWD), and left ventricular end systolic (LVESD) and end diastolic (LVEDD) were measured according to the American Society for Echocardiology (ASE) leading-edge method. For consistency, measurements were done from the anterior to the posterior mid points of the left ventricular cavity and were randomly repeated to ensure reproducibility (reproducibility was approximately 96%).
  • At four weeks of treatment, in vivo hemodynamic measurements were determined, as described below, both before and after infusion (0.2 ml over 1 minute) of 107 M isoproterenol via the femoral vein. Hearts were then excised and weighed as described below.
  • Alternatively, one hundred forty adult male Wistar rats (200-250 g) were anaesthetized and subjected to left coronary artery occlusion to produce AMI. Forty-eight hours after surgery, 2DE images were obtained and animals with a significant area of infarction were randomized to treatment with compound A (n=34) or vehicle (n=34).
  • Animals were treated by gavage 2 times per day for the duration of the experiment with compound A at 50 mg/kg or with vehicle alone. Serum level of drug was determined periodically to establish that treated animals received sufficient and consistent amount of drug and that the measured levels were sufficient to inhibit prolyl 4-hydroxylase.
  • Digital mid-papillary muscle and apical four chamber 2DE images were obtained biweekly on half of the animals in each group until week 8. Two observers blinded to treatment did measurements off-line. For the measurements, the digital images were slowed and frozen at end systole and end diastole. Two to three endocardial surfaces were traced in both the short axis and four chamber views and averaged. The left venticular area in systole and diastole, ejection fraction, fractional area change, wall thickness, mitral peak E wave velocity, aortic peak velocity, and infarct size were measured.
  • After 10 weeks of treatment, in vivo hemodynamic measurements were determined and hearts were excised and weighed as described below.
  • To collect in vivo hemodynamic measurements, animals were anaesthetized and the right carotid artery was dissected free from surrounding tissues and canulated with an SPR-671 ultra-miniature pressure transducer (Millar Instruments, Inc., Houston Tex.). The catheter was then advanced into the left ventricle. After steady state was established, baseline heart rate (HR), developed pressure (DP), contractile index (CI), left ventricle systolic pressure (SBP) and end diastolic pressure (LVEDP), and maximal rate of pressure rise and fall (+dP/dt and −dP/dt, respectively) were recorded.
  • Following hemodynamic measurement, hearts were excised and weighed. Pieces of scarred myocardium, and right ventricle and left ventricle myocardium distant from the site of infarct were dissected out and weighed. Hydroxyproline and proline were determined by the method of Palmerini et al. (1985, J Chromatogr 339:285-92) except that L-azetidine-2-carboxylic acid (Sigma-Aldrich) was substituted for 3,4-dehydroproline as the internal standard.
  • An immediate reduction in mortality was seen when compounds of the invention were administered following myocardial infarction. As can be seen in FIG. 8, no deaths were seen in the treated group immediately following insult to the heart, and over 90% of the treated group was still alive 8 weeks later. In comparison, only about 60% of the untreated group survived this period. Statistically significant improvement in survival (P<0.05) in the treated group relative to untreated group was seen at weeks 2 through 8, with a relative reduction in mortality of 77%.
  • Heart parameters were also improved in the treated group over the untreated group. Table 1 shows no increase in left ventricle end diastolic diameter (LVEDD) in the treated group, whereas the untreated group shows an increase in both LVEDD and left ventricle end systolic diameter (LVESD) measures over the same time period. The dilation of the heart in the untreated group was statistically different in the treated group relative to the untreated group after 1 week of treatment.

  • FIGS. 9A and 9B show graphical representations of the increase in LVESD and LVEDD, respectively, over time. The left ventricle end diastolic and systolic diameters were similar in the three groups at the time of randomization. FIG. 10A shows statistically significant improvement in left ventricular ejection fraction (LVEF) in treated animals relative to untreated controls in weeks 2 through 8. At randomization, the LVEF for both groups was 33%. The apparent increase in LVEF between week 4 and week 6 in the untreated control group reflects the high mortality in members of this group.
  • Fractional shortening of the myocardium during contraction was also improved in the treated group. Table 3 shows statistically significant improvement in fractional shortening in the treated group relative to the untreated group in weeks 1 to 4.

  • Further, as can be seen in FIG. 10B, fractional shortening in the treated group increased from 10% at baseline to 20% at week 2, a 79% increase relative to baseline. Both the untreated group and sham controls remained unchanged over the 4 week period.
  • The ability of the heart to contract and relax following trauma induced by cardiac ischemia was also improved in the treated group. Table 4A shows statistically significant differences in negative change in pressure over time (−dP/dt), a measure of the hearts ability to relax following contraction, in the treated group relative to the untreated group following 4 weeks of treatment. As shown in Table 4A and in FIG. 11, stimulation of the heart with isoproterenol shows statistically significant differences in positive change in pressure over time (+dP/dt), a measure of the hearts ability to contract, in the treated group relative to the untreated group.

  • Significant improvement was also seen at 10 weeks in developed pressure and systolic blood pressure in the treated group relative to the untreated group.
  • While it is recognized that recovery from an initial infarct requires connective tissue deposition within the necrotic region, the present invention demonstrates no adverse affects of treatment with respect to scar formation. On the contrary, as can be seen in Table 5A, there is no statistically significant change in collagen deposition in the scar and non-infarcted tissue at 4 weeks, demonstrating the improvement in heart performance in the first 4 weeks is unrelated to collagen deposition.

    Experiment II
  • Male Wistar rats (100-110 g), aged 4-5 weeks, were kept on a regular diet and a 12 hour day-night cycle. The animals were randomized into treatment regimens as follows: (1) Sham operated animals (n=12), (2) myocardial infarction controls (n=25), and (3) myocardial infarction with compound B treatment (n=25). Animals were treated for two days prior to surgery and for one week following surgery. Animals were treated by oral gavage two times per day with either 0.5% CMC (Sigma-Aldrich) (control) or 50 mg/kg compound B in 0.5% CMC. Ligation of the left anterior descending coronary artery was performed in artificially ventilated animals after left throacotomy. Animals were sacrificed one week after surgery and echocardiography was performed. Fractional shortening, end-diastolic diameters, and end-systolic diameters were determined in a blinded fashion.
  • As can be seen in FIG. 12A, fractional shortening was reduced from 51% in sham-operated animals to 29% in untreated MI controls. Treatment with compound showed a statistically significant (p<0.05; one-way ANOVA/Turey's test) improvement in fractional shortening, to 41%, relative to the untreated control group. Similarly, FIG. 12B shows statistically significant improvement in left ventricular end-diastolic (LVEDD) and end-systolic (LVESD) diameters in treated animals relative to untreated MI controls (p<0.005 and p<0.001, respectively; one-way ANOVA/Turey's test). Animals treated with compound showed no increase in left ventricular end-systolic diameter and an 18% increase in end-diastolic diameter over sham operated animals. The untreated controls, however, showed a 15% and 65% increase in LVESD and LVEDD, respectively.
  • Example 7 Liver Ischemia
  • Bickel et al. (1998; Hepatology 28:404-411) reported the use of a compound of the invention following induction of toxic-ischemic injury in the liver. Although the authors interpreted their results relative to the effect of the compounds on fibrosis, the authors acknowledged that the beneficial effects on variables of liver function including serum levels of bilirubin, bile acids, and alkaline phosphatase could not be directly attributed to a reduction in fibrosis.
  • The model of toxic-ischemic liver injury was described in Bickel et al. (supra). Briefly, male Wistar rats (212-320 g) either received 1 ml/kg carbon tetrachloride (CCl4) in olive oil (1:1) by gavage twice weekly for nine weeks (n=140) or received no treatment (controls; n=10). Additionally, a group of animals receiving CCl4 (n=60) also received compound P. The compound was administered by intraperitoneal injection twice daily at 60 mg compound/2 ml saline/kg body weight. After 9 weeks, the animals were sacrificed and the liver was weighed. Bilirubin, alanine transaminase, alkaline phosphatase, albumin, and total bile acids in serum were determined using commercially available kits.
  • As can be seen in Table 6 (Bickel et al., supra, Table 2), induction of liver damage produced a significant reduction in body weight (BW), although no significant change in liver weight was seen (not shown).
    TABLE 6
    Serum parameters of liver function after 9 weeks of treatment.

    Values in the table represent the mean ± standard deviation.
  • Liver damage also produced a measurable and statistically significant decrease in liver function as determined by serum levels of bilirubin (BR), total bile acids (tBA), alanine transaminase (ALT), and alkaline phosphatase (AP), which increased 117%, 856%, 201%, and 72%, respectively. However, treatment with a compound of the invention (CPD) produced statistically significant improvement in liver function. Serum levels of BR, tBA, ALT, and AP decreased 64%, 65%, 43%, and 65%, respectively, in the treated group relative to the untreated group. The improvement in liver function is attributed to stabilization of HIFα by the methods of the invention.
  • Example 8 Renal Ischemia-Reperfusion Injury
  • The model of ischemic acute renal failure was described in Nemoto et al. (2001, Kidney Int 59:246-251.) Briefly, male Sprague-Dawley rats (200-250 g) were treated with either 0.5% carboxymethyl cellulose (CMC; Sigma-Aldrich) or 1.5% compound B suspended in CMC by oral gavage in a volume of 4 ml/kg/day. Rats were pretreated daily for 4 consecutive days (days −3 to 0). A few hours after the fourth and last oral dose on day 0, renal ischemia-reperfusion injury (IRI) was performed.
  • Animals were divided into four groups: (1) Vehicle pretreatment and sham surgery; (2) compound B pretreatment and sham surgery; (3) vehicle pretreatment and IRI surgery; and (4) compound B pretreatment and IRI surgery. Animals were anesthetized under isoflurane, an incision was made in the abdominal midline, and the renal pedicles were bluntly dissected. A vascular clip was placed on the right renal pedicle for 45 minutes while the left kidney underwent simultaneous nephrectomy. After each occlusion, the clip was released at 45 minutes, and reperfusion was observed by the changing color of the kidney. Temperature was maintained constant, and warm saline (0.5% of body weight) containing Buprenex analgesic was administered directly into abdomen before the incision was completely sutured.
  • The animal body weight and mortality were monitored. Blood samples were obtained from the tail vein, and serum chemistry and CBC were measured by IDEXX veterinary service (West Sacramento Calif.). Data are presented as mean±SE with number of animals in parenthesis. The data were compared within the four groups at each time point using one-way analysis of variance (ANOVA, SIGMASTAT) and Student-Newman-Keuls method. A value of P<0.05 was considered significant.
  • As can be seen in FIG. 13, treatment with the compound prevented early mortality associated with ischemic-reperfusion injury. Further, serum blood urea nitrogen (BUN), a gauge of renal function, was significantly elevated by renal IRI at both 3 and 7 days, whereas treatment with compound produced significantly less IRI-induced increase in BUN. (FIG. 14A.) Additionally, serum cholesterol was significantly elevated by renal IRI at days 3, 7 and 14, whereas treatment with compound completely blocked IRI-induced increase in serum cholesterol. (FIG. 14B.) Athough the reasons are still under investigation, elevated kidney cholesterol is a natural reflection of renal ischemic-reperfusion injury. (Zager et al. (2001) Am J Pathol 159:743-752; Appel (1991) Kidney Int 39:169-183; and Abdel-Gayoum et al. (1999) Hum Exp Toxicol 18:454-459.)
  • Example 9 Enhanced Granulation Tissue Formation in Chronic Wounds
  • The ability to treat chronic wounds utilized the rabbit cutaneous hypertrophic scarring model described in Morris et al. (1997, Plast Reconstr Surg 100:674-681) and Marcus et al. (2000, Plast Reconstr Surg 105:1591-1599). Briefly, female New Zealand White rabbits (n=12; 3-6 months of age) were anesthetized and four, 7-mm dermal ulcer wounds were created on the ventral surface of each ear with removal of the perichondrium. Wounds were treated and covered with TEGADERM semi-occlusive polyurethane dressing (3M Health Care, St. Paul Minn.). Wounds were treated by topical application of 0.5% or 1% (w/v) a prodrug of compound V [pV] in an aqueous 0.5% (w/v) CARBOPOL 971 PNF gel (pH 6.5; Noveon Inc., Cleveland Ohio) once per day for the first week. When tested in vitro, gels released 50% of the drug within 2 hrs and 95% of the drug within 4 hrs. The treatment ear received either a low-dose treatment (0.5% compound) or a high dose treatment (1% compound), while the control ear received gel alone. Treatment delivery was facilitated by creating a hole in the dressing applied at the time of wounding to prevent irritation of the area surrounding the wound by daily removal of dressing. The hole was then covered by a smaller piece of dressing to prevent wound desiccation. Wounds with obvious desiccation or infection were excluded from the study.
  • At post-wounding days 7 and 12, wounds were harvested, bisected, and stained with hemotoxylin-eosin for evaluation of granulation tissue formation and wound epithelialization. Observers blinded to treatment quantitated wound healing parameters in histological sections by the use of a graduated eyepiece reticle. Data were analyzed using the Student's t-test to compare treated and untreated samples. A P<0.05 was considered significant.
  • The wounds were evaluated for granulation tissue formation and wound epithelialization; parameters of wound healing that are sensitive ischemia and hypoxia. (Corral et al. (1999) Arch Surg 134:200-205; and Ahn and Mustoe (1990) Ann Plast Surg 24:17-23.) As shown in FIG. 15A, an increase in granulation tissue area was seen in treated wounds relative to untreated wounds. As can be seen in FIG. 15B, there was no difference in the peak-to-peak distance in treated versus untreated animals. The peak-to-peak value is an indicator of wound coverage by granulation tissue. Thus, the methods of the invention can be used to increase vascularization and granulation tissue formation in wounds, such as chronic wounds and ulcers.
  • Example 10 Screening Assay
  • Compounds that inhibit HIF-specific prolyl hydroxylase activity and thereby stabilize HIFα can be identified and characterized using the following assay. A 50 μl aliquot of a reaction mix containing 4 mg/ml BSA, 0.1 M Tris HCl (pH 7.2), 2 mM ascorbate, 80 μM ferrous sulfate, 0.2 mM 2-oxoglutarate, 600 units/ml catalase, with or without 100 μM HIFα peptide is mixed with 50 μl HeLa cell extract or purified HIF prolyl hydroxylase and incubated 1.5 hours at 37° C. Following incubation, 50 μl of streptavidin beads are added and the mixture is incubated for 1 hour with agitation at 4° C. The mixture is transferred to tubes and centrifuged at low speed to pellet the beads. The beads are washed three times with 0.5 to 1 ml 20 mM Tris HCl (pH 7.2). The peptide is then eluted from the beads with 5 μl 2 mM biotin in 20 mM Tris HCl (pH 7.2) for 1 hour. The tubes are centrifuged to pellet the resin and 40-50 μl of supernatant is removed and an equal volume of acetonitrile is added. Alternatively, the peptide is attached to methoxycoumarin, a pH insensitive fluorophore. The fluorophore may provide sensitivity and specificity to enhance detection in assays run with crude cell lysate. An exemplary HIF peptide for use in the screening assay may comprise [methoxycoumarin]-DLDLEALAPYIPADDDFQL-amide (SEQ ID NO:5). The non-hydroxylated and hydroxylated peptides are then separated by reverse-phase HPLC on a C18 column with UV detection at 214 nm.
