Description

TECHNICAL FIELD The present invention relates to a pharmaceutical composition for preventing or treating vascular proliferative diseases,

The present invention relates to a pharmaceutical composition for the prevention or treatment of angioproliferative diseases comprising a mixed extract of Hwanggi, Angelica gigas and Angelica keiskei as an active ingredient, and a food composition for preventing or improving angioproliferative diseases.

Because every cell in our body feeds oxygen and nutrients from the blood vessels and removes waste products, microvessels spread like nets around every corner of our body. The innermost part of the blood vessel is composed of endothelial cells, and blood vessels are formed based on the three-dimensional arrangement of these endothelial cells.

Vascular diseases are caused by abnormal behavior of the endothelial cells, which is caused by over-production of blood vessels or excessive inhibition of angiogenesis. The diseases such as cancer, diabetic retinopathy, psoriasis, rheumatoid arthritis, chronic inflammation and the like are known as the vascular proliferative diseases in which blood vessels are excessively generated. On the other hand, the angiogenesis inhibitory diseases include myocardial infarction, And delayed regeneration of damaged tissue.

As described above, since the production of blood vessels has been reported to cause various diseases, the mechanism of inhibiting angiogenesis has become a target of various therapeutic agents. Currently used inhibitors of angiogenesis are either induction of apoptosis by inhibiting the activity of certain angiogenic promoters or by inhibiting the growth of vascular endothelial cells or by inducing angiogenic factors or indirect factors controlling endothelial cell viability And the like are used. However, these angiogenesis therapeutic agents have many side effects such as wound healing, or affecting the heart or kidney function, and it is urgent to develop therapeutic agents for vascular diseases without side effects.

Meanwhile, Astragalus membranaceus ) is a perennial herbaceous perennial plant, which is distributed in Korea, Japan, Manchuria, Northeastern China, and Eastern Siberia. It is often said that it is better to plant it as a herb, and to take it out in the autumn in one shot, to remove the outermost root and rootstock, and to dry it in the sun, and to use it without peeling it. It is prescribed for the weakness of the body, fatigue bloating, cold sweat and so on because it has the efficacy such as the tonic, the jihan, the diuretic, the exorcism. In addition, it has been reported that Huangzi extract inhibits angiogenesis by activating Tie2 of vascular endothelial cells, and has an effect of matured, normalized and stabilized blood vessels (Korean Patent Laid-Open No. 10-2014-0009278).

Angelica gigas is a dried perennial roots of Angelica gigas , a perennial paste that is very sweet and very warm. The efficacy of Angelica gigas has a blood-producing effect when blood is lacking. Angelica promotes blood flow in the coronary arteries and stimulates erythropoiesis. In addition, it has been reported that 50% ethanol extract of Angelica gigas Nakai can be used for the treatment of vascular restenosis, vascular stenosis and arteriosclerosis which are directly caused by abnormal proliferation of vascular smooth muscle cells by inhibiting proliferation of aortic smooth muscle cells (Korean Patent Laid-Open No. 10-2010-0047544).

Trichosanthes kirilowii Maximowicz) refers to the perennial root or the root of the yellow horntary which belongs to the genus Cucurbitaceae. There is no smell, the taste is spicy and the quality is cold. Treating petechiae, boils, and nausea when heat causes damage to the juice. It mainly produces lungs and stomach fever, so it helps to quench thirst and softens the body.

As described above, the various pharmacological effects of Hwanggi, Angelica gigas and Chrysanthemum are known, but the effect of these mixed extracts on vascular diseases has not been elucidated.

Under these circumstances, the present inventors have made intensive efforts to develop a therapeutic agent for angioproliferative diseases. As a result, the inventors of the present invention have found that herbal medicine extracts of Hwanggi, Angelica gigas Nakai and Chunghwa are not toxic to normal vascular endothelial cells but inhibit only angiogenesis by vascular endothelial cells The present inventors have completed the present invention.

As a result, as shown in FIG. 7, it was confirmed that the mixed herbal extract of the present invention remarkably suppressed the expression of VEGF-related MMP-9 in vascular endothelial cells.

Example  7. Invivo (in vivo In animal models Mixed herbal medicines for neovascularization  Analysis of the effect of extracts

Evans blue assay was performed to examine the effect of the mixed herbal extract of the present invention on neovascularization in the ear or the back skin of a mouse.

Specifically, mice were treated with 50 ng / ml of VEGF and 20 μg / ml of SH003 in the skin blood vessels of the mice, and after 30 minutes, Evans blue was injected. Mice were sacrificed and the ears or back tissues were isolated and photographed, and then Evans blue solution, which was immersed in formamide for 24 hours, and evolved from the ear or back tissue, was measured.

As a result, as shown in FIG. 8, in the group treated with SH003 of the present invention, the degree of staining with Evans blue was reduced compared with the group treated with VEGF, whereby SH003 inhibited neovascularization in the ear skin of mice Respectively. In addition, as shown in Fig. 9, in the group treated with SH003 of the present invention, the degree of staining with Evans blue was decreased as compared with the group treated with VEGF, Respectively.

From the above results, it was confirmed that the mixed extract of Hwanggi, Angelica gigas and Angelica keiskei according to the present invention has an excellent effect on the inhibition of angiogenesis.

Example  8. Mobility of vascular endothelial cells according to mixing ratio of mixed herbal extracts

The following experiments were carried out to confirm the ratio of Hwanggi, Angelica gigas and Angelica keiskei showing the best inhibitory effect on angiogenesis.

Specifically, mixed herbal medicine extracts containing Hwanggi, Angelica gigas and Angelica keiskei at a weight ratio of 5: 1: 1, 1: 5: 1 or 1: 1: 5, respectively, were further prepared. Then, a scratching assay using each of the extracts was carried out according to the method of Example 2 above.

As a result, as shown in Fig. 10, the extract of the mixture containing Hwanggi, Angelica and Angelica fractions at a weight ratio of 5: 1: 1, 1: 5: 1 or 1: 1: 5, respectively, had a weight ratio of 1: It was confirmed that the cell migration of HUVEC, which is a vascular endothelial cell, can be remarkably suppressed to a degree similar to or better than that of the extract containing HUVEC.

The mixed herbal medicine extract according to the present invention contains Hwanggi, Angelica gigas and Chrysanthemum at a weight ratio of 1: 1: 1 in a weight ratio of 5: 1: 1, 1: 5: 1 or 1: Which is the same as that of the extract. This suggests that the mixed herbal medicine extract prepared by changing the weight ratio of each component can inhibit not only the migration of HUVEC but also tube formation of HUVEC, infiltration of HUVEC and angiogenesis of an in vivo animal model.

From the above description, it will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. In this regard, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention should be construed as being included in the scope of the present invention without departing from the scope of the present invention as defined by the appended claims.
