Description

[0001] The present invention relates to a composition having eucalyptol as an active ingredient for enhancing muscle strength, muscle augmentation, muscle differentiation, muscle regeneration or muscle relaxation,

The present invention relates to a pharmaceutical composition for preventing or treating muscle diseases, which comprises Eucalyptol or a pharmaceutically acceptable salt thereof as an active ingredient.

In Korea, the elderly population accounted for 7.2% of the total population in 2000 and entered the aging society. By 2050, it is expected to enter the aging society (more than 20%). The muscle mass of a person decreases with age (10-15% at 50-70 years of age, and 30% at 70-80 years of age), resulting in a weakening of muscle strength and myofunction. This is followed by sarcopenia, Quot; Elderly myopenia leads to dysfunctional and gait disturbances and is a major cause of restricting the independent life of the elderly. In addition, myopenia reduces basal metabolic rate, increases insulin resistance, promotes the development of type 2 diabetes, and increases the risk of hypertension and cardiovascular disease by 3-5 times. Currently, there are no approved drugs for the treatment of myopinia. Drug repositioning techniques are being developed to apply myostatin inhibitors or other existing FDA-approved drugs to myopenia.

Muscles are divided into skeletal muscle, cardiac muscle, and visceral muscle, of which skeletal muscle is the most abundant in the human body, accounting for 40-45% of body weight. The skeletal muscle attaches to the bone through the tendon and acts to create movement or force of the bone. One muscle is made up of a number of muscle fibers, and the muscle fibers are made of numerous myofibers composed of actin and myosin. When actin and myosin overlap each other, muscle length is shortened or lengthened, causing overall muscle contraction and relaxation. An increase in myofibrillar size means an increase in muscle fiber thickness, resulting in an increase in muscle mass.

The types of muscle fibers constituting the muscles are mainly classified into Type I, Type IIA and Type IIB depending on the metabolic process that causes ATP and the rate of contraction. Type I muscle fiber is slow and has a large number of myoglobin and mitochondria and is suitable for sustained and low intensity aerobic activity. Type I muscle fibers are reddish, so they are also called red muscles, and the soleus is a typical example. On the other hand, 'Type IIB muscle fiber' has a very short contraction rate and is very short, but it is used for high intensity anaerobic exercise and has a low content of myoglobin and a white color. 'Type IIA muscle fiber' has the intermediate characteristics of the two muscle fibers mentioned above. As the age increases, not only does the composition of Type I and II muscle fibers vary, but also all types of muscle fibers decrease.

The skeletal muscle has characteristics that are regenerated and maintained according to the environment, but these characteristics disappear with aging, and as a result, as the aging progresses, the muscular volume decreases and the muscular strength is also lost. The signaling pathway involved in muscle growth and regeneration is signaling to regulate protein synthesis mediated by insulin like growth factor 1 (IGF-1) / AKT. Activation of IGF-1 receptor (IGF-1R) in muscle cell membranes increases AKT phosphorylation through IRS1 and PI3K phosphorylation and activates mTORC phosphorylation. Activation of mTORC increases phosphorylation of ribosomal protein S6 kinase beta-1 (p70S6K1), thereby increasing mRNA translation, increasing eukaryotic translation initiation factor 4 (eIF4G) activity, and inducing eukaryotic translation initiation factor 4E binding protein 1 < / RTI > (4E-BP1) protein. eIF4G and 4E-BP1 are involved in the formation of an eIF4F complex, that is, eIF4G binds eIF4A and eIF4E to form an eIF4F complex, while 4E-BP1 is phosphorylated to inhibit eIF4E binding and increase free eIF4E . The latter combines with other translation initiation factors (eIF4G and eIF4A) to form an eIF4F complex and the resulting eIF4F complex stabilizes the ribosome structure, facilitating translation initiation, ultimately increasing protein synthesis (Bodine et al., Akt / mTOR pathway is a crucial regulator of skeletal muscle hypertrophy and can prevent muscle atrophy in vivo, Nature cell biology, 3, 1014-1019, 2001).

In addition, AKT phosphorylation enhances eIF2B expression through glycogen synthase kinase 3 (GSK3), which promotes muscle fiber growth and suppresses muscle loss by suppressing expression of forkhead box O (FOXO), a proteolytic transcription factor. Muscle relaxation is regulated by signaling mediated by TGF-β family receptors including myostatin, transforming growth factor beta (TGF-β), and activin. The binding of the ligand to the TGF-β type II receptor phosphorylates the type I receptor, while the latter phosphorylates the smad 2/3 complex and ultimately activates FOXO. The latter increases the gene expression of muscle-specific ubiquitin-ligase, muscle RING-finger protein-1 (MURF1), Muscle Atrophy F-Box (MAFbx) / atrogin-1, which attaches ubiquitin to the lysine site of the target protein Promotes protein degradation, and ultimately leads to muscle loss. (Gumucio et al., Atrogin-1, MuRF-1, and sarcopenia, Endocrine, 43, 12-21, 2013).

The composition according to the present invention can increase the expression of p-4E-BP1 and p-p70S6K proteins or reduce the expression of MuRF1 (Muscle Ring-Finger Protein), MaFbx (Muscle atrophy F-box) . Specifically, p70S6K1, 4E-BP1, and eIF members are representative molecules involved in protein synthesis, and these three molecules are regulated by higher mTORCs. Activation of mTORc phosphorylates p70S6K1 and activated p70S6K1 phosphorylates the 40S ribosomal protein S6 to increase mRNA translation. Activation of mTORC also increases the activity of eIF4G and phosphorylates 4E-BP1, both of which are involved in the formation of the eIF4F complex. In other words, eIF4G binds eIF4A and eIF4E to form an eIF4F complex, while 4E-BP1 is phosphorylated, which inhibits binding to eIF4E and increases free eIF4E. The latter combines with other translation initiation factors (eIF4G and eIF4A) to form the eIF4F complex, which stabilizes the ribosome structure, thereby facilitating translation initiation and ultimately increasing protein synthesis.

Visualized bands were scanned on X-ray film and quantified using Quantity One analysis software (Bio-Rad).

FIG. 2 is a graph showing changes in expression of molecules involved in proteolysis and synthesis in eukaryotic cell-treated mouse myoblasts.

As shown in Fig. 2A, the amount of p-4E-BP1 and p-p70S6K1 protein, which are involved in protein synthesis, was significantly reduced compared to normal cells without dexamethasone (Basal) As shown, the proteolytic genes MaFbx / atrogin1 and MuRF1 expression were significantly increased. On the other hand, in Example 2 treated with eucalyptol, the amounts of p-4E-BP1 and p-p70S6K proteins reduced by dexamethasone were again significantly increased (Fig. 2A) and the expression of MuRF1 and MaFbx / atrogin1 (Fig. 2B). In other words, eucalyptol may be involved in increasing the amount of 4E-BP1 and p70S6K1 protein phosphorylation in murine myoblasts, ultimately increasing the amount of muscle by inhibiting MuRF1 and MaFbx / atrogin1 gene expression.
