Description

[0001] The present invention relates to a composition for preventing or treating vascular diseases,

The present invention relates to a composition for the prevention or treatment of vascular diseases containing an extract of Ischia officinalis.

In modern society, vascular disease is becoming a serious social problem. According to the statistics of death sources released by the National Statistical Office in 2010, vascular diseases including hypertensive diseases, ischemic heart diseases and cerebrovascular diseases were the second leading cause of death in Korea after malignant tumors, , And women who were 65 years or older reported a significant increase in mortality from vascular disease. Age, sex, hypertension, hyperlipidemia, diabetes, smoking, lack of exercise, and obesity are known to be risk factors for arteriosclerosis, which accounts for the largest portion of vascular disease. Patients with vascular disease receive continuous medication to treat the disease but are not easy to cure, and side effects from long-term administration of the medication are present.

Endothelium is the innermost of all blood vessels, including lymphatic and cardiovascular, and is composed of endothelial cells. Vascular endothelium plays a major role in maintaining vascular homeostasis such as vasodilation and contraction, vascular smooth muscle proliferation and migration, thrombogenesis and lysis. When the function of the vascular endothelium is interrupted, the vascular wall is damaged and vascular diseases such as atherosclerosis are induced.

The most important function of vascular endothelium is to secrete nitric oxide (NO). The production of NO is controlled by endothelial nitric oxide synthase (eNOS) present in vascular endothelial cells, and plays a role in producing NO by using L-arginine as a substrate. These eNOS are specifically expressed in vascular endothelial cells (smooth muscle cells), platelets, cardiac muscle cells, osteocytes, neurons and the like, NO generated by the action of eNOS is liberated into blood vessels and induced relaxation of vascular smooth muscle, Low density lipoprotein (LDL) oxidation, leukocyte adsorption, vascular smooth muscle cell proliferation, and platelet aggregation.

(Glueck, CJ 2010), myocardial infarction (Merx, MW et al., 2014), ischemic heart disease (Tratsiakovich, Y. et al., 2013), arterial sclerosis , Hell et al., 2014), hypertension (Na, S. et al., 2014), brain diseases such as stroke, cerebral infarction and cerebral hemorrhage (Li et al., 2014; Vellimana, AK et al., 2011) There have been a variety of attempts to treat various vascular diseases,

As described above, since the degradation of eNOS causes dysfunction of vascular endothelial cells such as atherosclerosis, a substance that promotes eNOS activity can be used as a candidate drug for improving chronic vascular disease. In fact, nebivolol, a third-generation beta blocker, is known to enhance vasodilatory effects through eNOS activation. The activity of eNOS is known to be regulated through various pathways such as calcium accumulation in endothelial cells, regulation of tetrahydrobiopterin coenzyme, phosphorylation, and the like. eNOS has various phosphorylation sites, and Ser-1177 phosphorylation has been reported to play an important role in the change of eNOS activity. Phosphorylation of ser-1177 of eNOS was induced by the estrogen receptor (Simoncini, T. et al., 2002), PI3-kinase / Akt (Hisamoto, K. et al., 1999), MAP kinase (Hisamoto, K. et al. 2001) and AMP kinase (Morrow, VA et al., 2003). In fact, women with postmenopausal women who have weakened estrogen secretion, which is a female hormone, have a significantly higher incidence of cardiovascular disease, which is the main cause of decreased eNOS activity. Therefore, the discovery of natural substances that enhance the enzyme activity by eNOS phosphorylation can be an important strategy for improving the vascular endothelial dysfunction and blood circulation.

On the other hand, arteriosclerosis refers to a functional impairment in which vascular endothelial cells do not maintain normal homeostasis due to genetic mutations, peroxidation, hypertension, increase in plasma homocysteine concentration, lipid accumulation in the blood vessels, microbial infection and the like. Lipid components such as cholesterol are deposited on the endothelium covering the innermost part of the blood vessel, hypertrophy of vascular endothelial cells occurs, atheroma is formed, blood vessel elasticity weakens or aging progresses, do. (ICAM-1), MCP-1 (monocyte chemoattractant protein-1), and P-selectin (VEGF) in vascular endothelial cells. the expression of adhesion molecules including E-selectin and E-selectin is increased and the expression of low density lipoprotein in blood, the inflow of mononuclear cells and macrophages, The process of activating is repeated to promote plaque formation in the blood vessels.

Adhesive substances such as VCAM-1, ICAM-1 and MCP-1 are known to be activated by reactive oxygen species (ROS) or tumor necrosis factor-α (TNF-α) (Yen, FL et al., 2013; Mackesy, DZ, 2014).

The adherent substance can firmly adhere cells and cells to maintain circularity, and functions to promote adhesion between leukocytes, vascular endothelial cells, white blood cells and extravascular tissues. In addition, leukocytes move through the blood vessels to move to the surrounding tissues, raise the awareness of T lymphocyte antigen, activate lymphocytes and monocytes of peripheral blood, and further enhance the action of activated lymphocytes. Through these functions, adherent substances play an important role in vascular diseases.

Acanthopanax koreanum is a deciduous shrub of the dicotyledonous decidua plant, and is a native species of Jeju native to the sea below 1400m above sea level in Jeju Island, South Korea (Korean Journal of Plant Resources, 1999, 12, 125-132). Branches are much split and fragrant, with broad thorns at the base. Leaves are alternate phyllotaxis. There are 3 ~ 5 small leaves. Egg is inverted or upside down. It has sharp sawtooth on edge and hairy on base of stem. The surface of the leaves is glossy and the back is light green. Flowers bloom from July to August, green, and hang on mountain-shaped inflorescence. The peduncle is 2 ~ 5㎝ long and the flower sack is long. The petals are 5, and calyx is faintly divided into 5 pieces. The fruit is flat with the nucleus and it grows black in October and the style remains. In the private sector, it has been used for back pain, neuralgia, and paralysis, and has traditionally been used as a medicinal product to lighten the body. It has been reported that it has anti-fatigue, anti-stress, central nervous excitement, metabolic stimulation, muscle strengthening, (National Federation of Forestry Cooperatives, 2005, Forest Regions 474, 112-114).

Meanwhile, the inventors of the present invention conducted research on a composition for treating vascular diseases, and confirmed that the extract of Ishigaki japonica had an effect of promoting eNOS activity in vascular endothelial cells. In addition, we confirmed that prior art that PPARγ activates PPARγ, which is the main compound present in the extract of Phellodendus japonicus, is related to arteriosclerosis, and that the content of impression acid As a result, it was confirmed that 0.27 mg (about 0.027%) was present per 1 g of the extract of Ishigaki. In addition, the transcriptional inhibition activity of inflammatory adhesion molecules was examined by treating the extract of Ishigaki japonicus and purified Impress acid, and it was confirmed that the transcriptional repression inhibitory activity was similar even though the amount of Impressic acid in the extract was very low. Thus, the present invention can be completed by confirming that the extract of Ishigaki japonica has excellent effect of preventing or treating vascular diseases.

As shown in Table 1, it was found that the 50% ethanol extract of P. ogalis leaf of Example 1 had a higher NO production ability than the extracts of Comparative Example 1-1 and Comparative Example 1-2. From further experiments, it was confirmed that the NO production ability of the extract of Ischia japonica L., extracted with 30% to 90% ethanol, was similar to that of the extract of P. japonicus extracted with 50% ethanol.

3, fluorescence expression of DAF-FM diacetate was greatly increased in cells treated with the extract of Ischia japonica leaf extract, but only the control (L-NAME) (NOS inhibitors) NO production was not observed in one group.

EXPERIMENTAL EXAMPLE 5. Confirmation of monocyte adhesion inhibition effect [

It was confirmed that 50% ethanol extract of Ishigaki leaves inhibits the adhesion of monocyte which is involved in the early stage of atherosclerosis in vascular endothelial cells.

To this end, HUVEC cells were seeded at 5 × 10 4 cells per well on a 48-well plate to attach the cells to the plate. Then, 5 μg / ml to 20 μg / ml of 50% Ml &lt; / RTI &gt; for 12 hours. Subsequently, 10 ng / ml of TNF-alpha was treated with HUVEC for 12 hours, monocytes (U937 cells) labeled with a fluorescent substance (Calcein green) were attached to a 48 well plate with the HUVEC and co-cultured for 1 hour. After co-cultivation, the cell culture medium was removed, and the cells were washed with PBS (phosphatized buffered saline) and fixed with 1% paraformaldehyde. The cells were fixed with fluorescence microscope, and monocytes The degree of adhesion was confirmed, and the results are shown in FIG.

4, the increase in monocyte adhesion in the TNF-a treated group compared with the control (control) group, whereas the treatment with 50% ethanol extract of Ishigaki japonica markedly decreased the adherence of mononuclear cells in a concentration-dependent manner . Therefore, it is expected that the extract of Ishigaki japonica inhibits the adherence of mononuclear cells in vascular endothelial cells, and thus it is expected to exert an excellent effect of inhibiting vascular diseases such as arteriosclerosis.

<Experimental Example 6: Inhibitory effect of ICAM-1 and VCAM-1 on the expression of islet oak leaf extract>

A luciferase promoter assay was used to confirm that 50% of the extract of Ogakiri leaf inhibited ICAM-1 and VCAM-1 protein expression in vascular endothelial cells.

The promoter activities of ICAM-1 and VCAM-1 were confirmed by luciferase assays using the luciferase assay system kit (Promega). To this end, HUVEC cells were seeded on a plate at a density of 5 × 10 4 cells / well in a 48-well plate, and then 1 μg of ICAM-1 or VCAM-1 promoter-luciferase (VCAM-1 promoter luciferase and 0.2 μg of pCMV-β-galactosidase were transfected with Lipofectamine ™ 2000 (Lipofectamine ™ 2000). After 4 hours, the cell culture broth was replaced with FBS-free medium, and the 50% ethanol extract of the osmanthus leaf of Example 1, the 100% ethanol extract of the osculus oak 100% of the Comparative Example 1-1 and the 5 g / Ml to 20 占 퐂 / ml were pre-treated for 12 hours in HUVEC, and then treated with 5 ng / ml of TNF-α for 12 hours. The cells were then lysed and centrifuged at 14,240 x g for 10 minutes, and the supernatants were assayed for luciferase and beta -galactosidase activity. The? -galactosidase assay contained 250 μl of assay buffer (0.12 M Na 2 HPO 4 , 0.08 M NaH 2 PO 4 , 0.02 M KCl, 0.002 M MgCl 2 , 0.1 M β-mercaptoethanol, 50 μg o- nitrophenyl -β-galactoside). The luciferase activity was leveled to the activity of? -Galactosidase, and the results are shown in Table 2 and FIG.
