The phrase “consisting essentially of” denotes the recited feature(s), element(s), method step(s), etc. and any additional feature(s), element(s), method step(s), etc. that do not materially affect the basic nature of the composition, system, or method. Many embodiments herein are described using open “comprising” language. Such embodiments encompass multiple closed “consisting of” and/or “consisting essentially of” embodiments, which may alternatively be claimed or described using such language.
As used herein, the term “histone acetylation code” refers to posttranslational modifications (e.g., acetylation) to histone proteins that serve as epigenetic markers and modify the expression of various genes and the activities of downstream pathways.
As used herein, the terms “histone acetylation code agent,” “histone acetylation code drug,” of variations thereof refer to agents or drugs (e.g., small molecules, peptide, antibodies, nucleic acids, etc.) that modify or alter (e.g., increase or decrease) the activity or expression of one or more factors involved in writing, erasing, or reading the histone acetylation code of are involved in pathways upstream or downstream thereof.
As used herein, the term “system” refers to two or more elements that are present together (e.g., as in a kit) but are not necessarily formulated into a single composition or contained in the same packaging.
The term “effective dose” or “effective amount” refers to an amount of an agent which results in a desired biological outcome (e.g., inhibition of osteoclast production and/or activity).
As used herein, the terms “administration” and “administering” refer to the act of providing a therapeutic, prophylactic, or other agent to a subject for the treatment or prevention of one or more diseases or conditions. Exemplary routes of administration to the human body are through space under the arachnoid membrane of the brain or spinal cord (intrathecal), the eyes (ophthalmic), mouth (oral), skin (topical or transdermal), nose (nasal), lungs (inhalant), oral mucosa (buccal), ear, rectal, vaginal, by injection (e.g., intravenously, subcutaneously, intratumorally, intraperitoneally, etc.) and the like.

The compositions also can include stabilizers and preservatives. For examples of carriers, stabilizers and adjuvants, see, e.g., Martin, Remington's Pharmaceutical Sciences, 15th Ed., Mack Publ. Co., Easton, Pa. (1975), incorporated herein by reference in its entirety.
Provided herein are agents that modulate histone acetylation and pathways downstream thereof, and methods for the treatment and prevention of organ injury therewith. In particular, provided herein are combinations of HDAC inhibitors, BET inhibitors, promoters of histone HAT activity, MR antagonists, NRF2 activators, and/or ALDH agonists, and methods of use thereof for the treatment and prevention of heart injury.
Histone acetylation is a post-translational modification (PTM) of histone proteins, which is regulated by specific proteins and read by specific epigenetic factors to mediate transcription and other cellular responses (Refs. 1-3; incorporated by reference in their entireties). The histone acetylation code is maintained and regulated by its writers, erasers, and readers (
Histone acetyl transferases (HATs) transfer acetyl groups to histone proteins. Acetyl-CoA is an evolutionarily conserved intermediate energy metabolite in TCA cycle for ATP production, as well as being the substrate for histone acetyltransferases (HATs) to transfer the acetyl-group to histone residues for histone acetylation (Refs. 9-10; incorporated by reference in their entireties). Acetyl-CoA serves as a gatekeeper or sensor between energy metabolism and gene expression/chromatin epigenetics by modulating the chromatin landscape in response to key nutritional cues (Refs. 11-18; incorporated by reference in their entireties). Metabolic carbon sources that swiftly produce acetyl-CoA (e.g., acetate, pyruvate, octanoate (8C), etc.) improve heart function in ischemia reperfusion (IR) rats. In particular, 8C administration of 160 mg/kg results in significant heart functional recovery when i.p. injected once at the time of reperfusion (Ref 19; incorporated by reference in its entirety).
Histone deacetylases (HDACs), which remove acetyl-group from histones to erase histone acetylation code, have been studied extensively for drug discovery. Numerous HDAC inhibitors have been identified in treating disease. For example, valproic acid (VPA), an FDA approved histone deacetylases (HDAC) inhibitor drug for bipolar disorders, protects the heart against AMI injury in rats (Refs. 12-13; incorporated by reference in their entireties). VPA has been shown in large epidemiologic studies to reduce the incidence of stroke and AMI (Refs. 14-15; incorporated by reference in their entireties). VPA has also been shown to affect the acetylation of the mineralocorticoid receptor (MR) and to reduce fibrosis in the heart, kidneys, lung and liver (Ref 14; incorporated by reference in its entirety).
While the histone acetylation code is typically written by HATs and erased by HDACs, a number of epigenetic factor families, in particular, bromodomain (BRD) containing epigenetic factors, such as BET BRD proteins, recognize the acetylation code and bind to the acetylated histones (Ref 11; incorporated by reference in its entirety). Studies have shown that JQ-1 can effectively halt heart failure and may protect cardiomyocytes under IR conditions (Ref 17; incorporated by reference in its entirety).
Other proteins are also acetylated by histone code writers and erasers in cell protection and organ repair. Histone code writers and erasers often acetylate or deacetylate other proteins to regulate their activities, which is an extension of the histone code. HATs and HDAC inhibitors can acetylate both nuclear factor erythroid 2-related factor 2 (NRF2) and mineralocorticoid receptor (MR) (refs. 14, 16; incorporated by reference in their entireties). The acetylation of NRF2 promotes its activity for cell protection whereas acetylation of MR inhibits its activity for cell protection. Therefore, in some embodiments, NRF2 activators, activators of ALDH, and MR inhibitors find use in histone acetylation code drug combinations.
Provided herein are combinations of histone acetylation code drugs and method of use thereof to treat and/or prevent organ (e.g., heart) damage therewith. In some embodiments, the combinations herein provide synergistic effects on myocardial cell protection, recovery from acute myocardial injury and subsequent thrombosis. The drug combinations herein synergistically in cell protection and organ repair and provide a therapeutic/prophylactic effect that exceeds those of the individual components.
In some embodiments, a subject that has suffered and event or is suffering from a disease or condition that may result in organ (e.g., heart tissue) damage is administered a composition or drug combination herein to treat or prevent damage to the organ. For example, patients suffer organ damage as a result of myocardial infarction. In some embodiments, a subject that suffers a myocardial infarction is administered (e.g., intravenously) a composition or drug combination herein administered a cocktail of histone acetylation drugs at the time of hospitalization after ischemic organ injury and during patients' stay at care unit. Patients will continuously take these drugs orally for a month after they are discharged from the hospital. The goal is to protect cell and organ damage post ischemic organ injury, such as heart, liver, kidney, limb and brain.
In some embodiments, provided herein are combinations of prophylactic and/or therapeutic agents (e.g., for co-administration to a subject) for the treatment and/or prevention of organ injury (e.g., heart injury).
In some embodiments, provided herein are compositions and/or combinations of drugs for administration to a subject comprising a histone deacetylase inhibitor (HDAC inhibitor, HDACi, HDI). HDIs have a long history of use in psychiatry and neurology as mood stabilizers and anti-epileptics. More recently they are being investigated as possible treatments for cancers, parasitic, and inflammatory diseases. Based on the homology of accessory domains to yeast histone deacetylases, the 18 currently known human histone deacetylases are classified into four groups (I-IV): Class I, which includes HDAC1, -2, -3 and -8 are related to yeast RPD3 gene; Class IIA, which includes HDAC4, -5, -7 and -9; Class IIB -6, and -10 are related to yeast Hda1 gene; Class III, also known as the sirtuins are related to the Sir2 gene and include SIRT1-7; Class IV, which contains only HDAC11 has features of both Class I and II. In some embodiments, a histone deacetylase inhibitor that finds use herein is selective for one or more classes of HDAC (e.g., Class I, Class IIA, Class III, and/or Class IV). In some embodiments, a histone deacetylase inhibitor that finds use herein is a general HDAC inhibitor. The “classical” HDIs act exclusively on Class I, II and Class IV HDACs by binding to the zinc-containing catalytic domain of the HDACs. These classical HDIs are classified into several groupings named according to the chemical moiety that binds to the zinc ion (except cyclic tetrapeptides which bind to the zinc ion with a thiol group). Some examples in decreasing order of the typical zinc binding affinity include: hydroxamic acids (or hydroxamates), such as trichostatin A; cyclic tetrapeptides (such as trapoxin B), and the depsipeptides; benzamides; electrophilic ketones; and aliphatic acid compounds such as phenylbutyrate and valproic acid. “Second-generation” HDIs include the hydroxamic acids vorinostat (SAHA), belinostat (PXD101), LAQ824, and panobinostat (LBH589); and the benzamides entinostat (MS-275), tacedinaline (CI994), and mocetinostat (MGCD0103). The sirtuin Class III HDACs are dependent on NAD+ and are, therefore, inhibited by nicotinamide, as well as derivatives of NAD, dihydrocoumarin, naphthopyranone, and 2-hydroxynaphthaldehydes. Any of the above HDIs may find use in embodiments herein.
Valproic acid (VPA) is a histone deacetylase inhibitor with potent anti-inflammatory effects. Inhibition of HDAC leads to epigenetic modifications that cause relaxation of the nucleosome structure allowing the transcription of many gene. VPA attenuate injury in various organ systems such as the lungs, kidneys, and brain. A variety of valproic acid derivatives are well known in the field. Experiments have demonstrated that valproic acid derivatives, such as valnoctamide (VCD) and c-Butyl-propyl-acetamide (SPD), exhibit similar biological characteristics to VPA (Neuman et al. Clinical Biochemistry 46 (2013) 1532-1537; incorporated by reference in its entirety). In some embodiments herein, a composition or drug combination comprises VPA or a valproic acid derivative. Exemplary VPA derivatives include VCD, SPD, and the VPA derivatives depicted in Table 3.
In some embodiments, a suitable VPA derivative comprises a 6-8 member alkyl chain. In some embodiments, the alkyl chain comprises one or more double or triple bonds. In some embodiments, the alkyl chain comprises (CH2)6, (CH2)7, or CH2)8. In some embodiments, the VPA derivative comprises a substituent at the 4 or 5 position of the alkyl chain. In some embodiments, the alkyl chain comprises a substituent at one or more additional positions.
In some embodiments, a valproic acid derivatives are branched carboxylic acids as described by Formula 1:
wherein R1 and R2 independently are saturated or unsaturated aliphatic C2-5, which optionally comprises one or several heteroatoms and which may be substituted, R3 is hydroxyl, halogen, alkoxy or an optionally alkylated amino group. Different R1 and R2 residues give rise to chiral compounds. The present invention encompasses the racemic mixtures of the respective compounds. The hydrocarbon chains R1 and R2 may comprise one or several heteroatoms (e.g. O, N, S) replacing carbon atoms in the hydrocarbon chain. Structures very similar to that of carbon groups may be adopted by heteroatom groups when the heteroatoms have the same type of hybridization as a corresponding carbon group. R1 and R2 may be substituted. Possible substituents include hydroxyl, amino, carboxylic and alkoxy groups as well as aryl and heterocyclic groups. In some embodiments, “COR3” is a carboxylic group. In other embodiments, R3 is a halide (e.g., chloride, bromide, etc.), ester, alkoxy, etc. According to the present invention, pharmaceutically acceptable salts of a compound of formula I can be used. Other VPA derivatives understood in the field are also within the scope herein.
In some embodiments, provided herein are compositions and/or combinations of drugs for administration to a subject comprising a bromodomain and extraterminal-containing protein family (BET) inhibitor (BETI). The bromodomain and extraterminal (BET) protein family (BRD2, BRD3, BRD4, and BRDT) are epigenetic readers that, via their bromodomains, regulate gene transcription by binding to acetylated lysine residues on histones and master transcriptional factors (Morgado-Pascual et al. Front. Pharmacol. November 2019, Vol. 10, Article 1315; incorporated by reference in its entirety). In some embodiments, a BET inhibitor comprises a thienodiazepine moiety or a derivative or variant thereof. Examples of BET inhibitors that find use in certain embodiments herein include JQ1, I-BET 151, I-BET 762, OTX-015, TEN-010 (JQ2), CPI-203, CPI-0610, olinone, RVX-208, ABBV-744, LY294002, AZD5153, MT-1, MS645, etc. In some embodiments, a BET inhibitor targets/binds to the first bromodomain (BD1) of a BET protein (e.g., olinone, etc.). In some embodiments, a BET inhibitor targets/binds to the second bromodomain (BD2) of a BET protein (e.g., RVX-208, ABBV-744, etc.). In some embodiments, a BET inhibitor is capable of targeting/binding both bromodomains (BD1/BD2) of a BET protein (e.g., I-BET 151, I-BET 762, OTX-015, TEN-010 (JQ2), CPI-203, CPI-0610, etc.). In some embodiments, a BET inhibitor is bivalent (e.g., AZD5153, MT-1, MS645, etc.).
In some embodiments, provided herein are compositions and/or combinations of drugs for administration to a subject comprising a promoter of histone acetyltransferase (HAT) activity. In some embodiments, a promoter of HAT activity is a acetyl-CoA, the substrate for histone acetyltransferases (HATs) to transfer the acetyl-group to histone residues for histone acetylation (Refs. 9-10; incorporated by reference in their entireties) In some embodiments, a promoter of HAT activity is a carbon source precursor to acetyl-CoA, such as citrate, acetate, pyruvate, and octanoate (8C). In some embodiments, the increased carbon/precursor content results in increase acetylation by HATs of histones.
In some embodiments, provided herein compositions and/or combinations of drugs for administration to a subject comprising a mineralocorticoid receptor antagonist. Mineralocorticoid receptor antagonists bind to and block the activation of mineralocorticoid receptors by mineralocorticoids such as aldosterone. Examples of mineralocorticoid receptor antagonists that find use in embodiments herein include spironolactone (an aldosterone receptor antagonist used for the treatment of hypertension, hyperaldosteronism, edema due to various conditions, hirsutism (off-label) and hypokalemia), eplerenone (an aldosterone receptor antagonist used to improve survival of patients with symptomatic heart failure and to reduce blood pressure), canrenoic acid (metabolized to canrenone in the body), canrenone, and drospirenone (a progestin used in oral contraceptive pills for the prevention of pregnancy and other conditions).
In some embodiments, provided herein compositions and/or combinations of drugs for administration to a subject comprising an aldehyde dehydrogenase agonist. Aldehyde dehydrogenases (ALDHs) are a family of detoxifying enzymes. The human genome has 19 known ALDH genes, but one ALDH, ALDH2, emerges as a particularly important enzyme in a variety of human pathologies. Aldehyde dehydrogenase activators (Aldas) are a family of small molecule activators of ALDHs, exemplified by lda-1 [N-(1,3-benzodioxol-5-ylmethyl)-2,6-dichlorobenzamide, MW 324]. Alda-1 is an allosteric agonist of ALDH2, and corrects a structural defect in the ALDH2*2 mutant present in 8% of the human population. Alda-89 [5-(2-propenyl)-1,3-benzodioxole, commonly known as safrole, MW=162] is a selective activator of acetaldehyde metabolism by ALDH3A1. Other Aldas that find use in embodiments herein include Alda-52 (1-methoxy-naphthalene-2-carboxylic acid (benzo[1,3]dioxol-5-ylmethyl)-amide), Alda-59 (4-[(benzo[1,3]dioxol-5-ylmethyl)-sulfamoyl]-thiophene-2-carboxylic acid amide), Alda-72 (N-benzo[1,3]dioxol-5-ylmethyl-2-(1-oxo-1,2-dihydro-2,3,9-triaza-fluoren-9-yl)-acetamide), Alda-71 (N-(4-methyl-benzyl)-2-(1-oxo-1,2-dihydro-2,3,9-triaza-fluoren-9-yl)-acetamide), Alda-53 (N-benzo[1,3]dioxol-5-ylmethyl-2-chloro-5-[1,2,4]triazol-4-yl-benzamide), Alda-54 (1-ethyl-4-oxo-1,4-dihydro-chromeno[3,4-d]imidazole-8-sulfonic acid (benzo[1,3]dioxol-5-ylmethyl)-amide), Alda-61 (5-(3,4-dimethyl-isoxazol-5-yl)-2-methyl-N-(4-methyl-benzyl)-benzene sulfonamide), Alda-60 (2-methyl-N-(4-methyl-benzyl)-5-(3-methyl-isoxazol-5-yl)-benzene sulfonamide), Compound Alda-66 (2-(2-isopropyl-3-oxo-2,3-dihydro-imidazo[1,2-c]quinazolin ylsulfanyl)-N-(4-methyl-benzyl)-propionamide), Alda-65 (N-(3,5-dimethyl-phenyl)-2-(2-isopropyl-3-oxo-2,3-dihydro-imidazo[1,2-c]quinazolin-5-ylsulfanyl)-acetamide), Alda-64 (2-(azepane-1-carbonyl)-N-(2-chloro-benzyl)-2,3-dihydro-benzo[1,4]dioxine-6-sulfonamide), Alda-84 (N-(2-hydroxy-phenyl)-3-phenyl-acrylamide), and any other suitable Aldas known in the field, for example, those described in U.S. Pub.

In some embodiments, the agents or combinations described herein (e.g., a combination of histone acetylation code drugs (e.g., a BET inhibitor, promoter of HAT activity, MR antagonist, ALDH agonist, NRF2 activator, and/or HDAC inhibitor, etc.)) are delivered by parenteral administration (e.g., intramuscular, subcutaneous, intravenous, epidural, intracerebral, intracereroventricular, etc.). Formulations suitable for parenteral administration may include physiologically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and non-aqueous carriers, diluents, solvents, or vehicles including water, ethanol, polyols (propyleneglycol, polyethylene-glycol, glycerol, cremophor and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Agents and combinations described herein (e.g., a combination of histone acetylation code drugs (e.g., a BET inhibitor, promoter of HAT activity, MR antagonist, ALDH agonist, NRF2 activator, and/or HDAC inhibitor, etc.)) may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank's solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally recognized in the field. For other parenteral injections, appropriate formulations may include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients. Such excipients are generally recognized in the field.
In certain embodiments, delivery systems for pharmaceutical agents and combinations (e.g., a combination of histone acetylation code drugs (e.g., a BET inhibitor, promoter of HAT activity, MR antagonist, ALDH agonist, NRF2 activator, and/or HDAC inhibitor, etc.)) may be employed, such as, for example, liposomes and emulsions. In certain embodiments, compositions provided herein also include an mucoadhesive polymer, selected from among, for example, carboxymethylcellulose, carbomer (acrylic acid polymer), poly(methylmethacrylate), polyacrylamide, polycarbophil, acrylic acid/butyl acrylate copolymer, sodium alginate and dextran.
In some embodiments, an agent or combination of agents (e.g., a combination of histone acetylation code drugs (e.g., a BET inhibitor, promoter of HAT activity, MR antagonist, ALDH agonist, NRF2 activator, and/or HDAC inhibitor, etc.)) is administered in a therapeutically/prophylactically effective amount. Thus, a therapeutically/prophylactically effective amount is an amount that is capable of at least partially preventing or reversing a disease, disorder, or symptoms thereof. The dose required to obtain an effective amount may vary depending on the agent, formulation, disease or disorder, and individual to whom the agent is administered.
Determination of effective amounts may involve in vitro assays in which varying doses of agent are administered to cells in culture and the concentration of agent effective for ameliorating some or all symptoms is determined in order to calculate the concentration required in vivo. Effective amounts may also be based in in vivo animal studies.
Pharmaceutical compositions may be in unit dosage forms suitable for single administration of precise dosages. In unit dosage form, the formulation is divided into unit doses containing appropriate quantities of one or more agents therapeutically/prophylactically.
Dosing and administration regimes are tailored by the clinician, or others skilled in the pharmacological arts, based upon well-known pharmacological and therapeutic considerations including, but not limited to, the desired level of therapeutic effect, and the practical level of therapeutic effect obtainable.
In some embodiments, and upon the clinician's discretion, the administration of the compounds may be administered for an extended period of time, including throughout the duration of the patient's life in order to treat the disorder or ameliorate or otherwise control or limit the symptoms of the patient's disease.
In a case wherein the patient's status does improve, upon the clinician's discretion the administration of the agents agents (e.g., a combination of histone acetylation code drugs (e.g., a BET inhibitor, promoter of HAT activity, MR antagonist, ALDH agonist, NRF2 activator, and/or HDAC inhibitor, etc.)) may be given continuously; alternatively, the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug holiday”). The length of the drug holiday can vary between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The dose reduction during a drug holiday may be from about 10% to about 100%, including, by way of example only, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, or about 100%.
In some embodiments, once improvement of the patient's symptoms/disorder/condition has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, can be reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. Patients can, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.
In some embodiments, the amount of a given agent that will correspond to such an amount will vary depending upon factors such as the particular compound, disease and its severity, the identity (e.g., weight) of the subject or host in need of treatment, but can nevertheless be determined in a manner recognized in the field according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. In general, however, doses employed for adult human treatment will typically be in the range of about 0.02-about 5000 mg per day, in some embodiments, about 1-about 1500 mg per day. The desired dose may conveniently be presented in a single dose or as divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.
Provided in certain embodiments herein are combination therapies in which the agents and drug combinations provided herein (e.g., a combination of histone acetylation code drugs (e.g., a BET inhibitor, promoter of HAT activity, MR antagonist, ALDH agonist, NRF2 activator, and/or HDAC inhibitor, etc.)) are co-administered with one or more additional agents for the treatment of the disorder/condition, a side effect of the primary agent, or a comorbidity of the disorder/condition. Co-administered agents do not have to be administered in the same pharmaceutical composition, and may, because of different physical and chemical characteristics, have to be administered by different routes. Co-administered agents may be administered concurrently (in the same or separate formulations/compositions) or at separate times (separated by minutes, hours, days, etc.) The co-administered agents may be administered concurrently (e.g., simultaneously, essentially simultaneously or within the same treatment protocol) or sequentially, depending upon the nature of the disease, disorder, or condition, the condition of the patient, and the actual choice of agent used. The determination of the order of administration, and the number of repetitions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the clinician after evaluation of the disease being treated and the condition of the patient.
Therapeutically-effective dosages can vary when the drugs are used in treatment combinations. Methods for experimentally determining therapeutically-effective dosages of drugs and other agents for use in combination treatment regimens are described in the literature. For example, the use of metronomic dosing, i.e., providing more frequent, lower doses in order to minimize toxic side effects, has been described extensively in the literature. Combination treatment further includes periodic treatments that start and stop at various times to assist with the clinical management of the patient.
For combination therapies described herein, dosages of the co-administered agents will of course vary depending on the type of co-drug employed, on the specific drug employed, on the disease being treated and so forth. In addition, when co-administered with one or more biologically active agents, the compound provided herein may be administered either simultaneously with the biologically active agent(s), or sequentially.
