Composition with pantothenic acid for the prevention and treatment of amyotrophic lateral sclerosis and Duchenne type muscle dystrophy

Description

[Technical Field]

[0001] The present invention relates to a pharmaceutical composition for prevention and treatment of myopathy, and more particularly, to a pharmaceutical composition for prevention and treatment of myopathy including calcium pantothenate, or calcium pantothenate and dimenhydrinate as active ingredients.[Background Art]

[0002] Muscular dystrophy is a genetic muscular disorder group that causes a deficient muscle fiber function due to regeneration of occluded muscles as well as weakening and destruction of muscle fibers through inflammation. Duchenne muscular dystrophy (DMD) is severe myopathy associated with an occluded dystrophin gene and causes myofascial defects associated with increased pro-inflammatory cytokines, mitochondrial dysfunction, and impaired satellite cell (muscle stem cell) polarity.

[0003] Meanwhile, amyotrophic lateral sclerosis (ALS) was first described by Bell in 1830 and named as ALS by Charcot in 1874. As the disease name implies, the ALS is a degenerative nervous system lesion clinically characterized by muscular atrophy, muscular weakness, fasciculation, and the like. The ALS is also called "motor neuron disease" because motor neurons of the external and spinal cord are selectively destroyed, and also called "Lou Gehrig's disease" or "Lou Gehrig disease", originating from the name of an athlete who suffered from the disease in the 1930s. The ALS is accompanied by degeneracy of both upper motor neurons (UMN) and lower motor neurons (LMN) and presents with symptoms of neural atrophy, emaciation, and fasciculation. Pathophysiologically, in the ALS, motor neurons of the central nervous system are destroyed, so that muscles do not exhibit a proper motor function in response to motor neuron stimulation. On the other hand, since sensory nerves, autonomic nerves, and the like distributed throughout the body are rarely invaded, sensory abnormalities or autonomic disorders are rarely exhibited clinically. As a pathogenesis of amyotrophic lateral sclerosis, about 10% shows constant heritability in the family, but most thereof is not yet clearly identified as in various sporadic degenerative nervous system lesions. The pathogenesis known to date is as follows. First, there may be excitatory toxic substances. The central nervous system, such as the cerebrum, the brainstem, and the spinal cord, consists of neurons that transmit signals and neuroglia required for maintaining the biological functions of neurons, and a role of a specific neurotransmitter is important between these neurons and neurons or between the neurons and the neuroglia. According to several studies so far, in the ALS, among many neurotransmitters, particularly, glutamate as an excitatory neurotransmitter, is present at a high concentration at the junction between motor neurons, and it is described that the substance will secondarily show a toxic effect on neurons to destroy the motor neurons. At this time, the concentration of glutamate is abnormally increased by a certain mechanism, and through a certain biological process, these glutamates cause excessive excitatory neurotoxicity in the motor neurons (Rothstein. Clin. Neurosci.3:348-359 (1995); Ikonomidou, Qin, Labruyere, and Olney J. Neuropathol. Exp. Neurol.55:211-224 (1996)). Second, there may be an autoimmune pathogenesis. In general, the immune system protects the body from internal and external invasions through cellular or humoral immune mechanisms. However, in special cases, autoantibodies are formed against antigens present in our body. In other words, as in other autoimmune diseases of the body, there is a theory that even in ALS, autoantibodies are formed against antigens present in the body, and secondarily, the motor neurons will be damaged. In ALS patients, antibodies (Anti-VGCC) are formed against a "potential-dependent calcium channel" located in a motor neuron membrane, and subsequently, a series of biological processes occur according to the antigen-antibody reaction, and eventually, motor neurons may be destroyed. Appel et al. detected anti-VGCC antibodies in about 80% of sporadic ALS patients and argued that the higher the antibody titer, the faster the disease progressed. However, it has been evaluated that there are still many areas to be identified even in the autoimmune pathogenesis. Third, there may be free radicals as the cause. Since Rosen et al. reported the gene mutation of a superoxide dismutase (SOD) enzyme in familial ALS patients in 1933, researches in this field have been very actively conducted. So far, it has been possible to reproduce experimental animals similar to a human ALS disease by performing the treatment on SOD transgenic mice. Recently, in the ALS Research Institute of Seoul National University Hospital, researches have been actively conducted to identify a role of free radicals in the pathogenesis of ALS through a series of experiments, such as infecting a motor neuron cell line with a mutant gene. Fourth, there may be a deficiency of neurotrophic factors. Like other cells in the body, motor neurons also require the role of appropriate neurotrophic factors in order to maintain smooth functions. In some cases, the supply of these neurotrophic factors may be blocked or their use may be limited, and thus the motor neurons may be destroyed. Representative neurotrophic factors important for the development, regeneration, and healing of the motor neurons include IGF-1, CNTF, BDNF, and the like, and in particular, the IGF-1 is known to have a very important function in a sprouting process of neurons. Finally, there may be abnormalities in the skeleton of the motor neurons. Aggregates or neurofilaments, which are not normally observed, are observed in the microstructure of spinal motor neurons of patients with ALS. However, it is not clear whether the aggregates or neurofilaments actually act as a causative factor in ALS or are products of the progression of ALS lesions. As a result, it is required to solve questions of what causes amyotrophic lateral sclerosis, what process gradually leads to a vicious cycle, and why motor neurons are selectively destroyed among many cells. It has been thought that the ALS is caused by a "multiple pathogenesis" in which an individual in a biologically vulnerable state is exposed to a specific external environment and exposed to various causative factors mentioned above to damage the motor neurons. Familial amyotrophic lateral sclerosis (ALS), which shows constant heritability in the family, refers to the onset of ALS transmitted genetically, and accounts for about 10% of overall amyotrophic lateral sclerosis. According to a recent announcement, it has been found that the ALS is a complex genetic disease inherited according to Mendel's law, and 10% of ALS patients are caused by genetic (familial) causes, and 20% thereof are associated with a Cu-Zn superoxide dismutase 1 (SOD1) gene. In particular, superoxide dismutase (SOD) plays a role in protecting cells from toxicity by converting superoxide ions into oxygen and hydrogen peroxide because free radical anions of superoxide ions have a harmful effect on cells. Antioxidant defense mechanisms by the SOD are important in almost all cells exposed to oxygen, and it is known that some lactic acid bacteria use other defense mechanisms. SOD1 is an antioxidant enzyme and found in the cytoplasm, mitochondria, and nucleus, and consists of 153 amino acids and acts as a 32 kDa homodimer. To date, 105 or more mutations in SOD1 causing ALS are known. It has been reported that the mutant antioxidant enzyme SOD1 causes the death of motor neurons through gain of function rather than loss of function. Due to the gain of function of SOD1, it has been estimated that mutant SOD1 causes motor neuron death through a combination of several mechanisms, such as mitochondrial functional defects, protein misfolding, weakening of the ubiquitin proteasome system, degradation of other proteins, and inappropriate growth factor signaling. Currently, many studies on ALS therapeutic agents are being conducted, but there is no fundamental treatment for ALS itself. In general, symptomatic therapy is recommended for patients with ALS to alleviate the symptoms complained of by the patients. Currently, drugs to be clinically prescribed include 'Riluzole', as an ALS therapeutic agent that has begun to be recognized as having the effect of prolonging the life overseas as a drug that delays the progression of ALS disease. The 'Riluzole' is a drug that suppresses excessive glutamic acid, which is considered one of the causes of destroying motor neurons.

[0047] Hereinafter, the present invention will be described in more detail with reference to the following Examples. However, the following Examples are only intended to embody the contents of the present invention, and the present invention is not limited thereto.Example 1. Confirmation of Lou Gehrig treatment effect 1-1. Confirmation of effect on ALS animal model

[0048] SOD1 G93A mice (B6SJL-Tg (SOD1 * G93A) 1Gur / J (Jackson Lab; stock no. 002726)), as only a Lou Gehrig mouse model showing both clinical and histopathological characteristics in patients with familial and sporadic Lou Gehrig's diseases were divided into total four groups of a drug non-administered group (PBS administration, n = 23), a dimenhydrinate (OC-501) administered group (30 mpk, n = 11), a calcium pantothenate (OC-504) administered group (30 mpk, n = 11), and a combined administered group (OC-501 + OC-504) (each 30 mpk, n = 11), and the drugs were administered intraperitoneally from the time the mice were 10 weeks old. The presence of symptoms and mortality were confirmed through a daily behavioral test set.

[0049] As a result, it was found that in the calcium pantothenate (OC-504) administered group and the combined administered group (OC-501 & 504), the total median duration of life was increased statistically significantly compared to the drug non-administered group (FIG. 1). In particular, in the drug non-administered group, the median duration of life after the appearance of Lou Gehrig's symptoms was about 5 weeks, but in the calcium pantothenate (OC-504) administered group, the duration of life of about 2 weeks was prolonged, and in the combined administered group (OC-501 & 504), the duration of life of about 10 days was prolonged (FIG. 2). When the median duration of life after the appearance of Lou Gehrig's symptoms in Lou Gehrig's patients was about 2 years (5 weeks of the median duration of life in the drug non-administered group), it can be seen that the life of about 2 weeks observed in the calcium pantothenate (OC-504) administered group was prolonged from the duration of life of about 9.6 months.1-2. Confirmation of effect of promoting myoblast differentiation and myogenesis

[0050] Mouse-derived C2C12 cells (KCTC, Biological Resources Center) were dispensed into a 12-well plate and incubated in a Dulbecco's modified Eagle's medium (DMEM) containing 1% penicillin / streptomycin and 10% fetal bovine serum (FBS) under conditions of 5% CO 2 and 37°C. When the cells reached 70 to 80% density, the cells were treated with a differentiation medium (DMEM medium containing 2% horse serum (H / S)) and DMSO (control group), dimenhydrinate (OC-501) 5 µM or 10 µM, calcium pantothenate (OC-504) 10 µM, or dimenhydrinate + calcium pantothenate (5 µM + 10 µM or 10 µM + 10 µM). At this time, 500 µM of H 2 O 2 (hydrogen peroxide) was treated with the differentiation medium to create conditions for inhibiting differentiation. Thereafter, the differentiation medium containing H 2 O 2 and the drugs were exchanged every 2 days. After 4 to 6 days, when the shape of myotubes was confirmed, the myotubes were added with 80 µl of a lysis buffer and then vortexed, and centrifuged for 10 minutes at 14000 rpm, and the obtained proteins were added with a 5X sample buffer and reacted in 95°C boiling water for 5 minutes. 8 µg of the reacted proteins was loaded on 8% and 12% SDS-PAGE gels, developed, and then transferred to a membrane. The membrane was blocked with PBST containing 5% skim milk at room temperature for 1 hour. The membrane was washed with 1X PBST, added with a primary antibody diluted at 1 : 1000, and then O / N reacted at 4°C. The next day, the membrane was washed with 1X PBST three times every 10 minutes, added with a secondary antibody diluted at 1 : 5000 in PBST containing 5% skim milk, and then reacted at room temperature for 1 hour. The membrane was washed with 1X PBST three times every 10 minutes, reacted in an enhanced chemiluminescent solution (ECL), and then exposed to an X-ray film to obtain a Western blot analysis result.

[0051] As a result of observing the cells, it was shown that myoblast differentiation was significantly increased in an OC-504 10 µM administered group, and it was shown that myoblast differentiation was significantly increased in a OC-501 5 µM and OC-504 5 µM combined administered group, a OC-501 5 µM and OC-504 10 µM combined administered group, a OC-501 10 µM and OC-504 5 µM combined administered group, and a OC-501 10 µM and OC-504 10 µM combined administered group (FIG. 3). In addition, as a result of confirming MHC and myogenin, as myoblast differentiation markers in cells, it was shown that in a DMSO group administered with only 500 µM of H 2 O 2 , the MHC and myogenin were decreased, but it was shown that in an OC-501 5 µM administered group, an OC-501 10 µM administered group, an OC-504 10 µM administered group, an OC-501 5 µM + OC-504 10 µM combined administered group, and an OC-501 10 µM + OC-504 10 µM combined administered group, the expression levels of MHC and myogenin were increased (FIG. 4). In addition, as a result of confirming the expression of 4-EBP and p70S6K, as sub-signals of an AKT / mTOR pathway associated with myogenesis, it was shown that in the OC-504 10 µM administered group and the OC-501 10 µM + OC-504 10 µM combined administered group, the expression of 4-EBP was increased compared to the control group (DMSO), and it was shown that even in the case of P70S6K, similarly, the expression of P70S6K was increased in the OC-504 10 µM administered group and the OC-501 10 µM + OC-504 10 µM combined administered group (FIG. 4). Through this, when the dimenhydrinate and calcium pantothenate were treated alone or in combination, the myoblast differentiation was promoted and the myogenesis was improved, and as a result, it was confirmed that the duration of life against Lou Gehrig's disease was prolonged.Example 2. Confirmation of treatment effect of Duchenne muscular dystrophy

[0052] In MDX mice (Jackso lab, stock no. 001801) (including point mutations in a DMD gene), as the most popular experimental model for testing Duchenne muscular dystrophy, older MDX mice over 40 weeks of age that maintained a homogenous transgenic state through mating and breeding and wild-type mice (normal mice) were anesthetized with isoflurane and then both tibialis anterior (TA) muscles were punctured 30 times each with a 26 G syringe (Korea Vaccine, Cat no. 27-00024-01) to induce physical muscle destruction. On day 3 after inducing muscle destruction, the mice were sacrificed and the TA muscles were separated, washed with 1X PBS (137 mM NaCl, 2.7 mM KCl, 10 mM Na 2 HPO 4 , 20 mM KH 2 PO 4 ) twice, and then chopped for 5 minutes with a razor blade, added in serum-free DMEM (GE healthcare, Cat no. SH30243.01) diluted with collagenase II (ThermoFisher, Cat no. 17101015) to a concentration of 2 mg / ml and digested for 1 hour. Thereafter, a supernatant was removed by centrifugation at 300 xg for 5 minutes, washed once with serum-free DMEM, and passed through a 70 µm strainer. A pellet obtained by centrifuging the filtered solution at 300 xg for 5 minutes was suspended in DMEM containing 10% FBS (ThermoFisher, Cat no. 16000-044) and 1X penicillin / streptomycin (GE healthcare, Cat no. SV30010) to isolate muscle satellite cells (MSCs). The MSCs obtained through 2 to 3 times subculturing were treated with PBS (CON), dimenhydrinate (OC-501) (100 µM), calcium pantothenate (OC-504) (100 µM), and dimenhydrinate and calcium pantothenate (OC-501 + OC-504) (each 100 µM), and then cell proliferation and growth were observed after 48 hours. In the experiment, the average and each standard deviation of measurement results of three or more times were obtained, and significance with the control was determined through T testing (*: p-val. < 0.05, **: p-val. < 0.01, ***: p-val. < 0.001).

[0053] As a result, OC-501 significantly promoted the proliferation of MSCs derived from wild-type mice (OC-501: 1.55, Combi: 1.40), and OC-504 significantly promoted the proliferation of MSCs derived from MDX mice. In particular, when OC-501 and OC-504 were co-treated, the growth of MSCs derived from MDX mice was significantly increased compared to that of MSCs derived from wild-type mice (FIG. 6). Through this, it was confirmed that both OC-504 alone and OC-501 + 504 combined administration had a muscle increasing effect in Duchenne muscular dystrophy.
