[0002] This application claims the benefit of U.S. Provisional Application Nos. 62 / 644,902, filed on March 19, 2018, and 62 / 644,932, filed on March 19, 2018, and 62 / 663,438, filed on April 27, 2018, and 62 / 697,198, filed on July 12, 2018. The disclosure of each of these applications is incorporated herein by reference. Summary of the invention
[0003] Potassium (K) is present on the plasma membrane of most cell types. + ) channels are the most diverse class of all ion channels and are associated with a variety of physiological functions, including the regulation of the electrical properties of excitable cells. The main pore-forming (α) subunits of these highly selective cation channels are divided into three major structural classes based on the number of transmembrane (TM) and pore (P) regions: 6TM / 1P, 2TM / 1P, and 4TM / 2P K + The International Union of Pharmacology (IUPHAR) designated the Kv7 gene (originally called KCNQ, a name assigned by the HUGO Gene Nomenclature Committee (HGNC)) as a voltage-gated K + The Kv7 subfamily consists of five homologous pore-forming α subunits, Kv7.1-7.5, which have typical voltage-gated K +Channel structure: has 6 TM regions (S1-S6) (flanked by intracellular N-terminal and C-terminal domains), a typical voltage sensor domain located in S4 composed of alternating positively charged residues, and a single P region between S5 and S6 of each subunit. These channels form tetramers of predominantly α subunits, either homotetramers or heterotetramers. Neurons are known to express Kv7 channels composed of Kv7.2-7.5α subunits. Some of these gene products may be distributed only in neurons, while others (e.g., Kv7.4 and Kv7.5) can be found in other tissues such as smooth and skeletal muscle.
[0004] Native M channels and corresponding macroscopic M currents were first characterized in amphibian sympathetic neurons. M channels are noteworthy because they activate at membrane potentials at or near the resting membrane potential of the neuron, exhibit slow activation and non-inactivation, and M currents are reduced by muscarinic cholinergic agonists, demonstrating a G-protein coupled receptor (GPCR) and physiological K + It was not until the cloning of this subfamily of genes that the pharmacological and biophysical properties of Kv7.2 / 7.3 (and possibly Kv7.5 / 7.3) heteromultimers and the elusive 'M' channels were determined, providing new and significant evidence for their importance in neuronal regulation.
[0005] The distribution of these channels (both regionally and developmentally) and their biophysical characteristics support their role in providing persistent resistance to the excitatory effects of depolarization. Under physiological conditions, as demonstrated by native M channels, they can very effectively modulate the subthreshold excitability of certain neuronal populations and play an important role in regulating the frequency and ultimately the pattern of action potential discharges in many types of neurons. Their importance in neuronal regulation is highlighted by the discovery that neuronal Kv7 mutations lead to benign familial neonatal convulsions (BFNC), indicating that reducing or eliminating the effects of Kv7.2 and Kv7.3 channels can greatly alter neuronal excitability. Mutational analysis demonstrates their involvement in BFNC and suggests that they may serve as targets for antiepileptic drugs (AEDs).
[0006] Unlike established GPCR pharmacology terms, K +The mode of action of channel modulators, especially compounds that activate channels, is still being refined. The use of voltage clamp techniques for ion channel pharmacology studies enables detailed biophysical studies of whole-cell currents or single channels, allowing for some characterization of the nature of compound-channel interactions, but does not prevent continued confusion surrounding terminology. The terms opener or activator are often used throughout the literature, but do not adequately describe the mode of action of all these "positive modulator" compounds. Generally, openers or activators are expected to increase the open probability of a channel or increase macroscopic current amplitudes, but this nomenclature is indeed overly simplistic. For example, the first publicly disclosed Kv7 opener, retigabine, has a complex and interesting profile because it has inhibitory activity at higher membrane potentials. Neuronal Kv7 channel openers can work in concert with channel activity within the "normal" activation voltage range and enhance currents without significantly affecting the activation threshold, while others significantly change the activation threshold. In addition, some openers seem to completely eliminate the voltage dependence of activation. It is not clear whether these effects represent a continuum, as these effects are often concentration-dependent. Clearly, the interaction patterns of compounds that can increase channel currents are complex and in most cases not fully understood, and the significance of these features for neuronal responsiveness and system physiology is unclear. Retigabine is moderately potent and not highly specific, but it is a very effective opener for Kv7.2, Kv7.5, and heteromultimeric Kv7 channels, and its action is characterized by a significant increase in channel currents over a narrow voltage range. As described above, at higher positive voltages, the opener is less effective, and under some conditions, the channel current is significantly reduced at higher positive voltages relative to the control current (this "cross" voltage dependence of the opener action is a feature of many neuronal Kv7 channel openers). This effect is also concentration-dependent and more pronounced at higher concentrations.
[0007] The compounds provided herein may be effective against Kv7.2 / 7.3 heteromultimers and / or at least have a bias relative to Kv7.4 homomultimers. These compounds may have reduced adverse side effects compared to retigabine. DETAILED DESCRIPTION

Experimental Section Solution 1
[0134] Scheme 1 shows a general method for the synthesis of lH-benzo[d]imidazol-2-ylamides 1.5. Appropriately substituted 1-fluoro-2-nitrobenzenes 1.1 are reacted with primary amines to give l-amino-2-nitrobenzenes 1.2. Alternatively, 1-chloro-2-nitrobenzene is reacted with primary amines under palladium catalysis to provide the desired l-amino-2-nitrobenzenes 1.2. The nitro group can be reduced to the corresponding amine by a variety of well-established methods to provide 1,2-diaminobenzenes 1.3. Reaction of 1.3 with cyanogen bromide affords lH-benzo[d]imidazol-2-amines 1.4. Coupling of the amides with appropriate carboxylic acids or acid chlorides can afford lH-benzo[d]imidazol-2-ylamides such as 1.5. Biological assays
[0135] Kv7.2 / 7.3 activation assay
[0136] The ability of compounds to enhance K currents in HEK cells containing Kv7.2 / 7.3 was assessed using planar patch clamp on the QPatch automated screening platform.
[0137] Cell Lines: hKv7.2 / 7.3 cell line was obtained from Chantest, Inc. (Cleveland, OH 44128) Catalog No. CT6147. These HEK cells express Kv7.2 / 7.3 ion channels when induced.
[0138] Cell culture: Cells were maintained in medium containing DMEM / F12 (50 / 50) (GIBCO catalog number 11330), 10% fetal bovine serum (FBS) (GIBCO catalog number 26140), 100 units / mL penicillin-streptomycin (GIBCO catalog number 15140), 0.005 mg / mL blasticidin (INVIVOGEN catalog number ant-bl-1), 0.5 mg / mL geneticin (GIBCO catalog number 10131), 0.1 mg / mL zeocin (GIBCO catalog number R25001). Cells for electrophysiological assays were maintained in medium without blasticidin, geneticin, and zeocin for 2 days, and channel expression was induced by adding tetracycline (BIOLINE catalog number BIO-87030) at a final concentration of 1 mg / mL. Cells were grown to approximately 75% confluence in T-175 flasks. Currents were recorded 24 hours after channel induction.
[0139] Compound Plate: Through the Biomek NX PTest compounds were prepared by serial dilutions on BECKMAN COULTER. Final dilutions were made in external recording solution with a final DMSO concentration of 0.1% DMSO. For single concentration screening, each plate had 10 μM retigabine as a positive control and 0.1% DMSO as a negative control.
[0140] Electrophysiology: On the day of the experiment, cells were washed with Hank's Balanced Salt Solution (HBBS) (Gibco catalog number 14175) and harvested with Tryple (Gibco catalog number 12604). The cells were then centrifuged at 2000 rpm for 5 minutes and centrifuged at approximately 3 x 10 6 Cells were resuspended in CHO-S-SFM (Gibco Catalog No. 12052) at 10 cells / mL. Cells were stirred for 30 minutes before starting the experiment. The external recording solution contained (in mM): NaCl (145), KCl (4), CaCl2 (2), MgCl2 (1), HEPES (10), and glucose (10); the pH was adjusted to 7.4 with NaOH, and the osmolarity was adjusted to 300-305 mOsM with sucrose when necessary. The internal solution contained (in mM): KCl (125), KF (10), EGTA (5), Na2ATP (5), MgCl2 (3.2), HEPES (5); the pH was adjusted to 7.2 with KOH, and the osmolarity was adjusted to 298-302 mOsM with sucrose.
[0141] Potassium channel activity was measured on QPatch HTX (Sophion Bioscience) using QPlate (48 wells / plate). Each cell was treated as an independent experiment and only one compound was tested per well. Potassium channel activity was elicited by holding at -80 mV and increasing to -30 mV for 2 s, followed by a 100 ms pulse to -120 mV.
[0142] Single concentration screening: Baseline conditions were obtained by recording 5 scans in external solution only (this operation was repeated three times for external solution). The effect of the test compound on the evoked current was then assessed by recording 5 scans in the presence of 3 μM compound solution. The steady-state current at the end of a 2 s pulse to -30 mV was measured to determine the fold increase relative to the baseline.
[0143] Table 2 summarizes the data from the Kv7.2 / 7.3 activation assay Table 2. Kv7.2 / 7.3QPatch single concentration screening results. a HPLC Method B b Increases in current relative to baseline from HEK cells co-expressing Kv7.2 / Kv7.3, measured using the Kv7.2 / 7.3 activation assay as described in the Biological Assay Methods section, at a compound concentration of 3 μM, are depicted as fold increases relative to baseline in the range of 1.2-2.9 (+), 3-3.9 (++), and >4 (+++); O indicates an open channel at the holding potential.
[0144] Thallium flux assay was used as a surrogate indicator of potassium channel activity.
[0145] The experimental protocol was adapted from the FluxORTMII Green Potassium Ion Channel Assay User Guide (Publication No. MAN0016084, Invitrogen). Conditions were optimized for the Kv7.2 / 7.3 cell line.
[0146] Cell lines: hKV7.2 / 7.3 cell line was obtained from Chantest, Inc. (Cleveland, OH 44128) catalog number CT6147.
[0147] Cell culture: Kv7.2 / 7.3 cells were maintained in medium containing DMEM / F12 (50 / 50) (Gibco catalog number 11330), 10% fetal bovine serum (FBS) (Gibco catalog number 26140), 100 units / mL penicillin-streptomycin (Gibco catalog number 15140), 0.005 mg / mL blasticidin (SIGMA 15205), 0.5 mg / mL geneticin (Gibco catalog number 10131), and 0.1 mg / mL zeocin (Gibco catalog number R25001). One day before the experiment, cells were seeded in 96-well clear bottom plates (Corning catalog number 353219) in medium without blasticidin, geneticin, or zeocin. Channel expression was induced by adding tetracycline (Bioline Cat. No. BIO87030) at a final concentration of 10 ng / mL.
[0148] Compound plates: Test compounds were diluted in a mixture of 0.1% DMSO / extracellular solution (eight point concentration range 0.014 μM to 30 μM). Serial dilutions were performed on a Biomek NXP (Beckman Coulter).
[0149] Measurements and data analysis: The ion channel modulating properties of novel compounds were characterized using a plate reader (Enspire, Perkin Elmer) with an excitation wavelength of 475 nm and an emission wavelength of 530 nm. After 15 seconds of baseline measurement, stimulation buffer containing thallium and potassium was injected. The final endpoint measurement was taken after 90 seconds. The response was normalized to the positive control (retigabine, maximum 30 μM). The average normalized response at each tested concentration was fit to the standard Hill equation to generate the EC50 and maximum response.

[0160] Embodiments relate to methods of treating amyotrophic lateral sclerosis in a subject diagnosed with definite amyotrophic lateral sclerosis, the method comprising administering to the subject a therapeutically effective amount of a compound having Formula A-1 to A-44 or B-1 to B-7 or a pharmaceutically acceptable salt thereof, wherein amyotrophic lateral sclerosis is treated. In embodiments, definite amyotrophic lateral sclerosis is defined by the El Escorial diagnostic criteria. In embodiments, the subject is a subject with definite ALS, a subject with an onset of amyotrophic lateral sclerosis symptoms for less than about 18 months, a subject with a plasma creatinine level of about 72 μM / L or greater, a subject concurrently administered with riluzole, a subject concurrently administered with dexpramipexole, and combinations thereof.
[0161] Amyotrophic lateral sclerosis (ALS; Lou Gehrig's disease) is a progressive, debilitating motor neuron disease characterized by degeneration and dysfunction / death of upper and lower motor neurons. ALS is usually fatal, but the rate of disease progression may not be linear.
[0162] According to the embodiments described herein, the El Escorial World Federation of Neurology ALS diagnostic criteria are as follows (see also Brooks, BR, RG Miller et al. (2000). "El Escorial revisited: revised criteria for the diagnosis of amyotrophic lateral sclerosis." Amyotrophic Lateral Sclerosis Other Motor Neuron Disord [ Amyotrophic lateral sclerosis Other motor neurone disorders ]1(5):293-9, which is incorporated by reference in its entirety). As used in the El Escorial World Federation of Neurology diagnostic criteria for ALS, the term "definite" is intended to mean that specific clinical exclusion criteria are met and no other diagnosis is possible based on clinical distribution or laboratory findings; the term "dementia" is intended to mean a progressive deterioration of specific cognitive functions; the term "onset" is intended to mean the time of the first subjective symptoms noticed by the patient and subsequently confirmed by examination; the term "likely" is intended to mean that specific clinical and exclusion criteria are met; the term "probable" is intended to mean specific clinical and exclusion criteria; and the term "worsening" is intended to mean an increase in muscle weakness in a previously affected segment or new onset of weakness in a previously unaffected segment.
[0163] The diagnosis of ALS requires the presence of: 1) signs of lower motor neuron (LMN) degeneration by clinical, electrophysiological, or neuropathological examination; 2) signs of upper motor neuron (UMN) degeneration by clinical examination; and 3) progressive spread of signs within one region or to other regions and absence of electrophysiological evidence of other disease processes that could explain the signs of LMN and / or UMN degeneration and neuroimaging evidence of other disease processes that could explain the observed clinical and electrophysiological signs.
[0164] In addition, the El Escorial World Federation of Neurology's ALS diagnostic criteria specify the following steps for the diagnosis of ALS. ALS is diagnosed by: 1) history, physical examination, and appropriate neurologic examination to identify clinical findings that suggest suspected, possible, probable, or definite ALS; 2) electrophysiologic examination to identify findings that confirm LMN degeneration in clinically relevant areas, identify LMN degeneration in clinically irrelevant areas, and exclude other disorders; 3) neuroimaging to identify findings that may exclude other disease processes; 4) clinical laboratory tests determined by clinical judgment to identify possible ALS-related syndromes; 5) neuropathologic examination (when appropriate) to identify findings that may confirm or exclude sporadic ALS, coexisting sporadic ALS, ALS-related syndromes, or ALS variants; 6) clinical and electrophysiologic examinations repeated at least six months apart to identify evidence of progression.
[0165] Definite ALS was defined based on clinical background alone as the presence of UMN and LMN signs in the medullary region and at least two other spinal territories, or the presence of UMN and LMN signs in three spinal territories. An important determinant for the diagnosis of definite ALS in the absence of electrophysiology, neuroimaging, and laboratory tests is the presence of UMN and LMN signs in multiple territories.
[0166] Probable ALS is defined based solely on clinical context as UMN and LMN signs in at least two regions. Although the regions may vary, certain UMN signs must precede (over) LMN signs. In patients with probable ALS, there may be many different combinations of UMN and LMN signs.
[0167] Probable ALS is defined based solely on the clinical context when UMN and LMN signs are present in only one area or only UMN signs are present in 2 or more areas or LMN signs precede UMN signs (the latter distribution of signs needs to be distinguished from multiple non-ALS processes). Unilimb ALS, progressive bulbar palsy without spinal UMN and / or LMN signs, and progressive primary lateral sclerosis without spinal LMN signs and progressive primary lateral sclerosis without spinal LMN signs constitute special cases that may develop LMN or UMN signs to meet the criteria for probable ALS over time or subsequently confirmed by specific LMN and UMN neuropathological findings at autopsy.
[0168] Although UMN pathology may be demonstrated at autopsy, suspected ALS only demonstrates LMN signs in 2 or more areas. However, at the time of diagnostic evaluation, only clinical signs are considered relevant for this classification.
[0169] The clinical signs of progressive LMN and UMN degeneration observed in ALS may occur: 1) in isolation (sporadic ALS), 2) in conjunction with other preexisting disease processes that do not develop concurrently with ALS (coexistent sporadic ALS), 3) in conjunction with laboratory-defined or epidemiologically defined abnormalities temporally related to ALS (ALS-associated syndromes), or 4) in conjunction with clinical, genetic, or epidemiological features that develop concurrently with ALS (ALS variants).
[0170] The physical and neurological examinations will allow a clinical diagnosis of ALS to be made to a certain degree of certainty as defined above; however, the history of disease onset, toxic exposures, past medical history, injuries, family history, geographic location, etc. must be combined with the clinical examination in determining whether the patient has an ALS-related syndrome or an ALS variant.
[0171] An ALS-related syndrome must meet clinical, electrophysiological, and neuroimaging criteria for possible, probable, or definite ALS. An ALS-related syndrome has unique laboratory-defined or epidemiologically defined features that are temporally related to the development of the ALS phenotype. If correction of the relevant laboratory-defined features does not result in correction of the ALS phenotype, patients should be considered to have an ALS-related syndrome in the same manner as patients with sporadic ALS.
[0172] ALS-related syndromes include: 1) monoclonal gammopathy (monoclonal gammopathy of undetermined significance, Waldenstrom's macroglobulinemia, osteosclerotic myeloma, etc.); 2) immune disorders and motor system degeneration (autoimmunity, high titer GMI ganglioside antibodies, etc.); 3) non-malignant endocrine abnormalities (hyperthyroidism, hyperparathyroidism, hypogonadism, etc.); 4) lymphoma (Hodgkin's lymphoma and non-Hodgkin's lymphoma); 5) infection (HIV-1, HTLV-I, encephalitis lethargica, varicella- Herpes zoster, brucellosis, cat scratch disease, Creutzfeldt-Jakob disease, syphilis, post-poliomyelitis, etc.); 6) acquired enzyme deficiency (detoxification enzymes, etc.); 7) exogenous toxins (lead, mercury, arsenic, thallium, cadmium, manganese, aluminum, organic pesticides, lupine seeds, etc.); 8) physical injury (electric shock, radiotherapy, etc.); 9) vascular (vasculitis; ischemic (Dejerine anterior medullary artery syndrome, etc.); 10) spinal cord myelopathy (painless myelopathy with no sensory signs, stable or progressive after surgery).
[0173] ALS variants must meet clinical, electrophysiological, and neuroimaging criteria for possible, probable, or definite ALS. The predominant presentation is seen in sporadic ALS but includes one or more of the following features, such as multiple phenotypes characterized by age of onset, site of onset, survival, and presumed inheritance.
[0174] Familial ALS variants in genetic linkage studies should be characterized by an established inheritance pattern in at least two generations and at least one clinically definitive or autopsy-proven case with convincing evidence to exclude other possible causes. Affected pairs occurring in a single generation are unlikely to be caused by a single gene effect.
[0175] Examples: a) ALS with defined inheritance and known gene product (hexosaminidase A / B deficiency, superoxide dismutase deficiency); b) ALS with defined inheritance and chromosomal linkage but no gene product (familial ALS linked to chromosome 21 or juvenile familial ALS linked to chromosome 2); c) ALS with defined inheritance and no known linkage or gene product (most cases or familial ALS); d) Geographic clustering (including disorders seen in the western Pacific, Guam, the Key Peninsula, northern Africa, Madras, etc.); e) Extrapyramidal signs (bradykinesia; cogwheel rigidity; tremor; clinically significant onset of supranuclear eye signs (pursuit abnormalities); familial or sporadic); f) Cerebellar degeneration (spinocerebellar abnormalities; familial or sporadic); g) Dementia (progressive cognitive abnormalities; familial or sporadic); h) Autonomic nervous system involvement (clinically significant abnormal cardiovascular reflexes; bowel or bladder control problems; familial or sporadic); i) Objective sensory abnormalities (decreased vibration sense; blunted discrimination; blunted cold sensitivity; familial or sporadic); j) Electrophysiological features in the diagnosis of ALS

For example, in certain embodiments, individuals diagnosed with ALS within two years or less can be treated with a compound of Formula A-1 to A-44 or B-1 to B-7 or a pharmaceutically acceptable salt thereof to reduce, eliminate or slow the progression of ALS or ALS-related symptoms, such as, for example, loss of fine motor function, loss of gross motor function, loss of bulbar function, and loss of respiratory function. In other embodiments, a compound of Formula A-1 to A-44 or B-1 to B-7 or a pharmaceutically acceptable salt thereof can be administered to reduce or slow the progression of symptoms, including, but not limited to, tremors, loss of muscle control, loss of writing ability, loss of ability to move or turn over, loss of speech, inability to swallow, difficulty breathing, etc. In other embodiments, individuals with advanced symptoms or individuals diagnosed with ALS more than two years prior to the start of treatment can be treated with a compound of Formula A-1 to A-44 or B-1 to B-7, or a pharmaceutically acceptable salt thereof, and such individuals can respond to treatment by showing a reduction or elimination of one or more symptoms associated with ALS, or in certain embodiments, for example, the rate of onset or progression of symptoms can be reduced; the rate of loss of motor function, loss of speech, and / or difficulty swallowing can be slowed and / or reduced.
[0186] In embodiments, a therapeutically effective amount of a compound of Formula A-1 to A-44 or B-1 to B-7, or a pharmaceutically acceptable salt thereof, is administered to a subject, and the decline in muscle loss is reduced. In embodiments, a therapeutically effective amount of a compound of Formula A-1 to A-44 or B-1 to B-7, or a pharmaceutically acceptable salt thereof, is administered to a subject, and the decline in serum creatinine is reduced.

[0332] In an embodiment, the method further comprises administering one or more active agents simultaneously or concurrently with administering a compound of formula A-1 to A-44 or B-1 to B-7 or a pharmaceutically acceptable salt thereof. In an embodiment, the one or more active agents are dextrorotatory pramipexole, riluzole, baclofen, tizanidine or edaravone. Riluzole is a neuroprotectant that blocks sodium channels in an inactivated state. Riluzole has been shown to prolong the survival of ALS patients. In an embodiment, riluzole is administered once or twice a day at 50 mg. In an embodiment, dextrorotatory pramipexole is administered at a total daily dose of 150 mg or 300 mg or 600 mg. In an embodiment, baclofen is administered at 0.05 mg, 0.5 mg, 1 mg, 2 mg, 5 mg, 10 mg or 20 mg. In an embodiment, tizanidine is administered at 2 mg, 4 mg or 6 mg. In an embodiment, edaravone is administered at 30 mg. In an embodiment, the one or more active agents are dextrorotatory pramipexole. In an embodiment, the one or more active agents are riluzole.
[0333] In an embodiment, one or more active agents are anti-glutamatergic or ion channel blockers, such as, but not limited to, FP-0011, memantine, N-acetylated-α-linked acid dipeptidase (NAALADase) inhibitors, nimodipine, or a combination thereof. Excessive levels of glutamate have been shown to be toxic to neurons, and evidence suggests that both direct and indirect glutamate toxicity may lead to the pathogenesis of motor neuron degeneration in diseases such as ALS. FP0011 is an anti-glutamatergic compound that can reduce presynaptic glutamate levels and show powerful neuroprotective properties. Memantine is a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist that has been shown to protect neurons from NMDA or glutamate-induced toxicity in vitro and in animal models of neurodegenerative diseases. In an embodiment, memantine is administered at 2 mg, 5 mg, 7 mg, 10 mg, 14 mg, 21 mg, or 28 mg. N-acetylated-α-linked acid dipeptidase (NAALADase) converts N-acetyl-aspartyl-glutamate into glutamate during neuronal damage and may represent a new method to block excess glutamate release in the treatment of neurodegenerative disorders without interfering with normal brain function. Nimodipine is a dihydropyridine calcium channel blocker that can antagonize excitatory amino acid receptor activation to reduce calcium entry into damaged neurons and may help slow or reverse ALS. In an embodiment, nimodipine is administered at 30 mg or 60 mg.
[0334] In an embodiment, one or more active agents are mitochondrial energy promoters, such as but not limited to resveratrol, creatine, erythropoietin, cholest-4-ene-3-one oxime (TRO-19622) and combinations thereof. Resveratrol is a powerful antioxidant found in red grape skins, and has been found to inhibit calcium influx into cells associated with glutamate-induced cytotoxicity. In an embodiment, resveratrol is administered at 100mg, 500mg, 1000mg or 1500mg. Creatine contributes to the formation of ATP (the main source of cellular energy in the body), and has been shown to provide a protective mechanism against neurodegenerative diseases by stabilizing cell membranes and mitochondrial energy transfer complexes (which can reduce motor neuron death by improving mitochondrial function). Creatine can also reduce oxidative stress and increase glutamate uptake, and can help reduce muscle strength loss in ALS patients. In an embodiment, creatine is administered at about 750mg to about 5 grams. Erythropoietin (EPO) is a glycoprotein hormone that controls erythropoiesis, red blood cell production, and has recently been identified as a cytokine with a variety of neuroprotective effects (including, for example, reducing inflammation, enhancing survival signals, and preventing neuronal cell death). Cholesterol-4-ene-3-one oxime (TRO-19622) is a low molecular weight compound that enhances motor neuron survival and growth by interacting with protein components of the mitochondrial permeability transition pore, and can rescue motor neuron cell bodies from axonomy-induced cell death in vivo. In an embodiment, one or more active agents are creatine.
