Description

Parkinson's disease preventive or therapeutic composition comprising a bee odor extract or fractions thereof as an active ingredient

The present invention relates to a composition for the prevention or treatment of Parkinson's disease, which comprises the bee herb extract or fractions thereof as an active ingredient.

As the aging phenomena, which are increasing in proportion to the elderly population, have recently emerged as a social problem, there is a growing interest in neurodegenerative disorders. Degenerative brain diseases are disorders in which motor, memory, and cognitive disorders are caused by neurodegenerative diseases caused by various causes. Among them, Parkinson's disease is the most common neurodegenerative brain disease after Alzheimer's disease. . Parkinson's disease was first described in 1817 by James Parkinson, a British medical doctor, about 60 years later, the term Parkinson's was used by J.Charout, and by Kinner wilson in 1912, Parkinson's disease It was found that the disease is related to the extrapyramidal system and not the pyramidal system (Habibi et al., 2011).

Research into the cause of Parkinson's disease has been undertaken for decades, but the mechanism is not clear. As a result, Parkinson's disease is classified as a progressive neurological disorder intractable disease without effective and effective long-term treatment (Pan et al., 2008, Habibi et al., 2011). However, it is estimated that Parkinson's disease is caused by various pathological factors occurring in Parkinson's disease patients. As a factor, the abnormal killing of dopamine-releasing neurons among the neurotransmitters distributed in the melanoma of the midbrain is disrupted or destroyed by the substantia nigra par compacta (Camins et al., 2008, Smith). , 2008). Abnormal death of dopamine neurons occurs through a series of processes. First, mitochondria damaged by various factors, such as the environment, heredity, and aging, cause functional degradation of the proteolytic system, which causes abnormal proteins and organelles. It is caused by accumulation and not decomposition. These causes raise the importance of proteolytic systems in the treatment and prevention of Parkinson's disease.

To date, the highest prescription for Parkinson's disease patients is L-dopa, which is a treatment that increases the level of dopamine in the blood by direct injection of Levodopa, a precursor of dopamine neurons. Direct infusion of Levodopa results in substantial symptomatic relief in Parkinson's patients, but increased doses are essential for long-term use and are known to cause a variety of unforeseen side effects as the dose increases (Rock and Peterson, 2006). , McGeer and McGeer, 2008). Therefore, it is urgent to develop more fundamental treatments and drugs that can suppress the protection and death of nerve cells that facilitate dopamine secretion, rather than the direct administration of L-dopa, which increases dopamine blood levels. As one of these attempts, research into the development of therapeutic agents targeting autophagy, one of the proteolytic systems, has recently attracted attention.

Autophagy, or autophagy, is derived from the Greek word for "self," meaning "self," and "eating," meaning to eat. It not only maintains the metabolic balance of the cell but also affects the fate of the cell. It is known as a mechanism of self-sacrifice that plays an important role (Eisenberg-Lerner et al., 2009). This autophagy acts as a precursor to autophagosomes and is a morphological form of autophagosomes, which are independent bilayers, which gradually extend the edges of cells to completely surround unwanted proteins in the cell, forming vesicles. It has a characteristic structure. In addition, autophagosomes move along microtubules to fuse with lysosomes in cells and form autolysosomes, which are reported to degrade proteins by proteolytic enzymes secreted inside lysosomes. It became.

On the other hand, Aster koraiensis Nakai is a compositae plant, also called Gymnaster koraiensis (Nakai) Kitamura, and is a native plant of Korea. Beetle odor is a perennial herb distributed mainly in Jeju Island and sub-Gyeonggi Province, and is known to grow well in valleys and wetlands with high humidity. Known so far the efficacy of these bee and herb extract and single compound (compound) of diabetic retinopathy induced mouse retinal vascular damage, protective effect of the detoxification enzymes known to have cancer prevention effect, bee anesthetic extract of Protein glycation and aldose reductase inhibitory activity against a single component and anti-apoptosis activity against diabetic mouse models, including inhibition of the development of diabetic nephropathy, colon cancer suppression, liver protection, and oxidative stress Effect. However, there have been no studies on autophagy, including Parkinson's disease, through bee anesthesia.

Accordingly, while the present inventors are conducting research on the development of a prophylactic and therapeutic agent for Parkinson's disease through induction of autophagy, the extract of Aster koraiensis Nakai plants induces autophagy and at the same time prevents and prevents Parkinson's disease. The present invention was completed by confirming that it is very effective for treatment.

It was confirmed that the decrease significantly.

As a result, as can be seen in Figure 14, in the case of the MPTP single treatment group. While the expression of Beclin-1 protein, a representative protein that induces autophagy, was decreased compared to the control group, it was confirmed that concentrations were significantly increased in the group administered bee anesthetized extract and fractions.

In the above results, the treatment of bee-flavored extracts and fractions in the Parkinson's disease-induced animal model with MPTP toxin promotes the amount of TH, an enzyme that modulates the precursor of dopamine (L-DOPA) (FIG. 8), and in Parkinson's disease. Inhibits aggregation of α-synuclein protein in abnormally aggregated form (FIG. 9), increases expression of autophagy membrane protein LC3 and p-AMPK, p-ULK1, Beclin-1 proteins that induce autophagy; It was confirmed that the expression of p-mTOR protein that inhibits autophagy is reduced (Figs. 10-14).
