Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application is a continuation-in-part application
claiming benefit of priority to PCT/KR02/02000, filed on Oct. 25,
2002, the contents of which are incorporated by reference herein
in its entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a composition comprising
Horse chestnut extract having anti-angiogenic and matrix metalloproteinase
inhibitory activity for the prevention and treatment of diseases
caused by abnormal angiogenesis and its use thereof.
[0004] 2. General Background and State of the Art
[0005] Angiogenesis is the process of generating new capillary
blood vessels. Neovascularization is tightly regulated, and activation
occurs in embryogenic development, tissue remodeling, wound healing
and periodic cycles of corpus luteum development (Folkman and Cotran;
Int. Rev. Exp. Pathol., 16, pp207-248, 1976).
[0006] Vasculogenesis means the formation of new endothelial cell
during the embryogenesis in order to supply the nutrient for rapidly
growing fetus. On the contrary, capillary blood vessel endothelial
cells are started to proliferate from existing vasculature in angiogenesis.
The endothelial cells are growing very slowly as compared with other
types of cells in the body. However, the proliferation of these
cells is induced by pro-angiogenic cytokines, inflammation mediators
and activated proteolytic enzymes.
[0007] By the failure of regulation of angiogenesis, some pathological
syndromes are developed (Timar; J. Pathol. Oncol Res., 6, pp85-94,
2001). Pathological angiogenesis is involved in many diseases. For
example, cardiovascular diseases such as angioma, angiofibroma,
vascular deformity, atherosclerosis, synechia and edemic sclerosis;
and opthalmological diseases such as neovascularization after cornea
implantation, neovascular glaucoma, diabetic retinopathy, angiogenic
corneal disease, macular degeneration, pterygium, retinal degeneration,
retrolental fibroplasias, and granular conjunctivitis are diseases
related to angiogenesis. Chronic inflammatory diseases such as arthritis;
dermatological disease such as psoriasis, telangiectasis, pyogenic
granuloma, seborrheic dermatitis and acne are also angiogenesis-dependent
diseases.
[0008] In particular, angiogenesis is essential to metastasis and
growth of cancer (D'Amato R J and Adamis A P, Ophthalmol., 102,
pp1261-1262, 1995; Arbiser J L, J. Am. Acad. Derm., 34, pp486-497,
1996; O'Brien K. D. et al.; Circulation, 93, pp672-682, 1996; Hanahan
D and Folkman J, Cell, 86, pp353-364, 1996). New blood vessels not
only provide nutrients and oxygen to fast-growing cancer cells,
but also give ways of entering the blood stream resulting metastasis
(Polverini P. J., Critical Reviews in Oral Biology, 6, pp230-247,
1995). Currently, a large variety of chemotherapies and immunotherapies
are applied in the treatment of cancer, but the efficacy of the
therapies is limited and nothing can successfully extend the life
of cancer patients due to the lack of anti-metastasis effects.
[0009] Arthritis, a well-known inflammatory disease, is initiated
as an autoimmune disease. As the progression of the inflammation,
the growth of vascular endothelial cell in the synovial cavity is
activated by the cytokines. The cartilage in the articulation is
finally destroyed by the formation of articular lamina leak (Kocb
A E, et al., Arth. Rheum., 29, pp471-479,1986; Stupack D G, et al.;
Braz. J. Med. Biol. Rcs., 32, pp578-581, 1999; Koch A E; Arthritis
Rheum., 41, pp951-962, 1998).
[0010] Many people are losing their eyesight all over the world
because of various ocular diseases. Many patients become blind due
to the infiltration of the capillary blood cells into the vitreous
humor (Jeffrey M I and Takayuki A, J. Clin. Invest., 103, pp1231-1236,
1999). Therefore, inhibition of angiogenesis is the basic therapeutic
modality for these diseases.
[0011] Psoriasis is caused by extremely active proliferation of
skin cells. Fast-growing cells requires sufficient blood supply,
and angiogenesis is abnormally induced in psoriasis (Folkman J.,
J. Invest. Dermatol., 59, pp40-48, 1972).
[0012] Since angiogenesis is closely related to initiation and
progression of many diseases, many efforts have been made toward
the development of angiogenesis inhibitors in order to prevent and/or
treat those diseases.
[0013] Not only reorganization of the blood vessel by migration,
proliferation and differentiation of endothelial cells, but also
degradation of the extracellular matrix is required for angiogenesis.
One of the major events for inducing angiogenesis is a breakdown
of the extracellular matrix before the formation of the capillary
blood vessels. The most important enzyme of matrix degradation is
matrix metalloproteinase (MMP), a family of over 20 proteins. MMPs
are endopeptidase, which degrade or proteolyze the components of
the extracellular matrix such as collagen, proteoglycan, and gelatin,
and are classified into four groups: collagenase, gelatinase, stromelysin,
and membrane-type MMP. Many enzymes in the MMP family have substrate
specificity. The expression of MMP is induced under various physiological
circumstances when remodeling of an extracellular matrix is required
(Curry T E Jr., Osteen K G; Biol. Repord., 64, pp1285-1296, 2001;
Damjanovske S, et al., Ann. NY. Acad. Sci., 926, pp180-191, 2000;
Ravanti L, Kahari V M, Int. J. Mol. Med.; 6, pp391-407, 2000).
[0014] Increased expression or activation of MMPs is observed in
many pathological states, such as atherosclerosis, restenosis, MMP-dependent-osteopathy,
inflammation of the central nervous system, Alzheimer's disease,
skin aging, rheumatoid arthritis, osteoarthritis, septic arthritis,
corneal ulcer, synechia, bone disease, proteinuria, abdominal aortic
aneurysm, regressive cartilage loss, myelinated nerve loss, liver
fibrosis, nephroglomerular disease, germinal membrane ruptures,
inflammatory bowel disease, gingivitis, periodontitis, senile macular
degeneration, diabetic retinopathy, proliferate vitreous body retinopathy,
immature retinopathy, eye inflammation, conical cornea, Sjogren's
syndrome, myopia, eyes tumors, rejection of cornea implantation,
angiogenesis and cancer metastasis. (Woessner Jr., Ann. NY. Acad.
Sci., 732, pp11-21, 1994; Warner et al., Am. J. Pathol., 158, pp2139-44,
2001; Stetler-Stevenson, Surg. Oncol. Clin. N. Am., 10, pp383-92,
2001).
[0015] For example, stromelysins are known to be the major enzyme
for disruption of cartilage (Murphy, G. et al., Biochem. J., 248,
pp265-268, 1987). Collagenases, gelatinases and stromelysins are
responsible for the degradation of the extracellular matrix in many
retinopathies (Bruns, F. R. et al., Invest. Opthalmol. and Visual
Sci., 32, pp1569-1575, 1989). Collagenases and stromelysins are
identified in fibroblast from gingiva in inflammation, and the activity
of the enzyme is dependent on the degree of inflammation (Overall,
C. M. et al., J Periodontal Res, 22, pp81-88, 1987). MMP activity
is highly enhanced in response to the bacterial infection and inflammation
in gingival crevicular fluid taken from patients with periodontal
disease. Destruction of collagen, a major structural component of
the periodontal matrix, by MMP leads to gingival recession, pocket
formation and tooth movement (Goulb, L B., Ryan M. E. Williams R.
C., Dent. Today, 17, pp102-109).
[0016] Recent reports have also shown that MMP-1 activity is highly
induced in Alzheimer's disease, and MMP-1 and MMP-3 are involved
in the pathophysiology of the disease (Leake A, et al.; J. Neurosci.
Lett., 291, pp201-3, 2000; Yoshiyama Y, et al., Acta Neuropathol.
(Berl), 99, pp91-5, 2000).
[0017] MMPs are also responsible in solar UV radiation-induced
skin damage, affecting skin tone and resiliency leading to premature
aging. The symptom of that include leathery texture, wrinkles, mottled
pigmentation, laxity and sallowness. Therefore, MMP inhibitors could
be included in cosmetics for anti-photoaging or anti-wrinkle treatment
(Hase T, et al., Br. J. Dermatol., 142, pp267-273, 2000; Fisher
G. J, et al.; Photochem. Photobiol., 69, pp154-157, 1999).
[0018] Since inhibitors of MMP and angiogenesis can be applied
to the treatment and prevention of many diseases, development of
angiogenesis inhibitor as new therapeutics is expected. Since these
inhibitors need to be administered for a long time, desirable inhibitors
should not have toxic or adverse effect with good patient compliance.
[0019] Horse chestnut is a plant in Hippocastanaceae, cultivated
in many countries in Europe and Asia. Triterpene saponin mixture
known as aescin (also called escin) consists of diacylated tetra-
and pentahydroxy-beta-amyrin compounds is a chief component of the
seeds. Various flavonoids and polysaccharides are also included
in the seeds. In addition to aescin, the leaves contain hydroxycoumarin
such as esculin, fraxin and scopolin and flavonoids including rutin,
quercitrin and isoquercitrin.
[0020] In folk medicine, the leaves have been used as a cough remedy.
Japanese Horse chestnut seeds are given to patient with gastric
pain, malaria, and diarrhea. Purified extract from Horse chestnut
seed can be used for preparation of traditional Japanese cakes.
[0021] Horse chestnut seeds are used for treatment of symptoms
in chronic venous insufficiency, because of anti-exudative and vascular
tightening effects of the principal ingredient of seed extract,
aescin.
[0022] Periodontal (gum) diseases, including gingivitis and periodontitis,
are serious infections that, left untreated, can lead to tooth loss.
Periodontal disease is a chronic bacterial infection that affects
the gums and bone supporting the teeth. Periodontal disease may
affect one tooth or many teeth. It begins when the bacteria in plaque
causes the gums to become inflamed. In the mildest form of the disease,
gingivitis, the gums redden, swell and bleed easily. Gingivitis
is often caused by inadequate oral hygiene. Gingivitis is reversible
with professional treatment.
[0023] Untreated gingivitis can advance to periodontitis. With
time, plaque can spread and grow below the gum line. Toxins produced
by the bacteria in plaque irritate the gums. The toxins stimulate
a chronic inflammatory response, and the tissues and bone that support
the teeth are broken down and destroyed. Gums separate from the
teeth, forming spaces between the teeth and gums that become infected.
As the disease progresses, the spaces deepen and more gum tissue
and bone are destroyed. Eventually, teeth can become loose and may
have to be removed.
[0024] Some of the main causes of periodontal disease is bacterial
plaque. However, factors like the following also affect the health
of the gums, such as smoking, genetics--up to 30% of the population
may be genetically susceptible to gum disease. Stress is another
cause.
[0025] The most common ones include the following. Gingivitis is
the mildest form of periodontal disease. It causes the gums to become
red, swollen, and bleed easily. There is usually little or no discomfort
at this stage. Gingivitis is reversible with professional treatment
and good at home oral care. Aggressive periodontitis is a form of
periodontitis that occurs in patients who are otherwise clinically
healthy. Common features include rapid attachment loss and bone
destruction and familial aggregation. Chronic periodontitis is a
form of periodontal disease resulting in inflammation within the
supporting tissues of the teeth, progressive attachment and bone
loss and is characterized by pocket formation and/or recession of
the gingiva. It is recognized as the most frequently occurring form
of periodontitis. It is prevalent in adults, but can occur at any
age. Progression of attachment loss usually occurs slowly, but periods
of rapid progression can occur. Also, periodontitis may be a manifestation
of systemic diseases, such as diabetes. Necrotizing periodontal
diseases is an infection characterized by necrosis of gingival tissues,
periodontal ligament and alveolar bone. These lesions are most commonly
observed in individuals with systemic conditions including, but
not limited to, HIV infection, malnutrition and immunosuppression.
[0026] Periodental diseases may be treated by surgery such as pocket
reduction, soft tissue grafts, regeneration procedures, crown lengthening.
[0027] The present inventors have studied the inhibitory effect
of Horse chestnut extract on angiogenesis and matrix metalloproteinase
and have discovered that the Horse chestnut extract could be used
to inhibit a variety of angiogenesis- and MMP-dependent diseases,
including early and late stage periodontal diseases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0060] In the present application, "a" and "an"
are used to refer to both single and a plurality of objects.
[0061] Horse chestnut of the present invention comprise Japanese
Horse chestnut (Aesculus turbinata Blume), Chinese (Aesculus chinensis
Bge and Aesculus wilculus Rehd) and European (Aesculus hippocastanum
L.) and the inventive extract is extracted from the leaves or the
seeds from Japanese, Chinese or European Horse chestnut.
[0062] Horse chestnut extract of the present invention can be purchased
or prepared with conventional methods. Commercially available Horse
chestnut extract can also be used.
[0063] An inventive extract may be prepared in accordance with
the following preferred embodiment.
[0064] For the present invention, Horse chestnut leaves are dried
at room temperature and cut into small pieces. Quick dried-seeds
at 30-40.degree. C. or non-dried seeds are used and mashed or pulverized.
The each powder is mixed with 3 to 10-fold, preferably, 5 to 7-fold
volume of water, alcohols such as methanol, ethanol, butanol and
the like, or the mixtures thereof, preferably, the mixture of water
and methanol, more preferably 80% methanol; and is heated at a temperature
ranging from 30 to 100.degree. C., preferably from 50 to 80.degree.
C., for a period ranging from 1 to 48 hours preferably 3 to 10 hours,
with 3 to 10 times, preferably 7 times, by sonication, reflux or
conventional extraction to obtain an aqueous crude extract. The
crude extract is centrifuged, filtered and then lyophilized to obtain
an extract powder. The powder is stored at 4.degree. C. until use.
[0065] In accordance with an aspect of the present invention, there
is also provided a anti-angiogenic composition comprising Horse
chestnut extract for inhibiting angiogenesis.
[0066] In accordance with another aspect of the present invention,
there is also provided a pharmaceutical composition comprising Horse
chestnut extract as an active ingredient for prevention and treatment
of various diseases associated with angiogenesis.
[0067] Horse chestnut extract of the present invention inhibited
angiogenesis not only in tube formation assay, but also in mouse
Matrigel model when it was orally administered.
[0068] The tube formation assay is an in vitro experimental method
that is closely related to in vivo efficacy, and this method investigates
the microvascular network of the human endothelial cell. In vivo
angiogenesis can be quantitatively measured in mouse Matrigel assay.
[0069] The extract of Horse chestnut inhibits MMP, a family of
essential enzymes for angiogenesis and cancer metastasis. When the
effect of Horse chestnut extract on MMPs was investigated with MMP-2
and MMP-13, it drastically inhibited activities of both enzymes.
The inhibitory effect of Horse chestnut extract on MMPs is not,
however, limited to these enzymes.
[0070] It is therefore clear that Horse chestnut extract of the
present invention is available as a drug for angiogenesis- and/or
MMP-dependent diseases since it inhibits angiogenesis and MMPs.
[0071] As mentioned above, Horse chestnut extract of the present
invention has inhibitory effects on angiogenesis and MMP activity.
While MMPs are enzymes responsible for angiogenesis, anti-angiogenic
activity of Horse chestnut extract is not limited to MMP inhibition
activity of the Horse chestnut. That is, MMPs are one of the factors
for inducing angiogenesis, and Horse chestnut extract can inhibit
other factors of angiogenesis. Furthermore, MMP inhibitory activity
of Horse chestnut are not limited to inhibition of angiogenesis.
[0072] In accordance with another aspect of the present invention,
there is also provided a composition comprising Horse chestnut extract
having MMP-inhibitory activity.
[0073] In accordance with another aspect of the present invention,
there is also provided a pharmaceutical composition comprising Horse
chestnut extract as an active ingredient for prevention and treatment
of various MMP-dependent diseases.
[0074] The inventive pharmaceutical composition can be used to
prevent and treat angiogenesis- and/or MMP-dependent diseases, such
as atherosclerosis, restenosis, MMP-dependent osteopathy, inflammation
of central nervous system, Alzheimer's disease, skin aging, acne,
rheumatoid arthritis, osteoarthritis, septic arthritis, corneal
ulcer synechia, bone disease, proteinuria, abdominal aortic aneurysm,
regressive cartilage loss, myelinated nerve loss, liver fibrosis,
nephroglomerular disease, germinal membrane rupture, inflammatory
bowel disease, gingivitis, periodontitis, senile macular degeneration,
diabetic retinopathy, proliferate vitreous body retinopathy, immature
retinopathy, eye inflammation, conical cornea, Sjogren's syndrome,
myopia eye tumor, rejection of cornea implantation, angiogenesis,
infiltration and cancer metastasis and so on.
[0075] The composition of this invention may be used by itself
or included with more than one of other angiogenesis inhibitors,
such as ticlopidine, glucosamine (2-amino-2-deoxy-D-glucopyranose)
and Ginkgo biloba extract for the prevention and/or treatment of
angiogenesis- and MMP-dependent diseases. We have previously reported
that angiogenesis is inhibited by commercially available pharmaceutical

and accompanying figures. Such modifications are intended to fall
within the scope of the appended claims. The following examples
are offered by way of illustration of the present invention, and
not by way of limitation.
EXAMPLES
[0102] The following examples are intended to further illustrate
the present invention. However, these examples are shown only for
better understanding the present invention without limiting its
scope.
Example 1
Preparation of Extract from Horse Chestnut Leaf and Seed
[0103] Dried Horse chestnut leaves (500 g) or seeds (200 g) were
crushed by blender and soaked in 2 L of 80% methanol. The solution
was kept at 50.degree. C. for 12 hrs and further extracted by sonication.
The filtrate was concentrated by vacuum evaporator. Finally, 120
g of the extract from leaves and 53 g of the extract from seeds
were obtained and used in the following examples.
Example 2
Identification of the Constituents of the Horse Chestnut Extract
[0104] Crude extract of Horse chestnut of the above EXAMPLE 1 was
suspended in distilled water and extracted with 1 L of ethylacetate.
After drying and solubilization in ethanol, an aliquot of the extract
was subjected to paper chromatogrphy (BuOH:HAc:H.sub.2O=4:1:5 vs.
2% ethylacetate)
[0105] From R.sub.f values with the standard compounds, the four
main spots of the extract were identified as aescin, quercitrin,
esculin and esculetin, respectively.
Experimental Example 1
Effect of Horse Chestnut Extract on Tube Formation of HUVEC
[0106] The effect of Horse chestnut extract on angiogenesis was
investigated in vitro with human endothelial cells.
[0107] In order to do the tube formation assay, blood vessel endothelial
cells, human umbilical vein endothelial cells (HUVECs), were isolated
from freshly obtained cords after cesarean section according to
Grant's method (Grants D S, et al., Cell, 58, pp933-943, 1989).
They were identified by immunocytochemial staining with anti-Factor
VIII antibody. HUVECs grown with Matrigel (BD Bioscience, Bedford,
Mass., USA), were treated with the above Horse chestnut extract
of the Example 1, and further incubated at 37.degree. C. for 8-16
hrs. As a control, above procedure was repeated without Horse chestnut
extract.
[0108] FIG. 1 shows that a tubular network is formed as a process
of neovascularization, when they are grown on Matrigel.
[0109] FIGS. 2, 3 and 4 are pictures showing that the HUVECs grown
on Matrigel treated with Horse chestnut extract cannot generate
the microvascular network.
[0110] In order to identify the component responsible for anti-aniogenic
acvity of Horse chestnut extract, components identified as in EXAMPLE
2, were subjected to the tube formation assay as described above.
Since those chemicals are not soluble in water, they were dissolved
in dimethyl sulfoxide (DMSO). In order to exclude the effect of
solvent, HUVECs treated with the same amount of DMSO were used as
a control. FIG. 5 is a picture of the 1% DMSO-treated HUVEC control,
and FIGS. 6-9 are pictures showing the effect of individual components
of the Horse chestnut on tube formation. At 50 .mu.M concentration,
aescin completely inhibited the formation of microvascular network
of HUVEC. Tubular network was disconnected by treatment with 50
.mu.M of quercitrin, and esculetin. The extent of inhibition of
tube formation by esculin was less than that by esculetin, aglycon
of the esculin.
[0111] The area of the tube was determined by image analysis program
Image-Pro Plus.RTM. (Media Cybernetics, USA), and the results were
summarized in Tables 1 and 2. As shown in Table 1, Horse chestnut
extract inhibited HUVEC tube formation in a dose-dependent manner.

Experimental Example 2
Animal Experiment for Angiogenesis (Mouse Matrigel Model)
[0113] The anti-angiogenic activity of Horse chestnut extract was
quantitatively measured in mouse Matrigel model.
[0114] 0.4 Ml portion of Matrigel mixed with 50 ng/Ml of basic
fibroblast growth factor (bFGF) and 50 units/Ml of heparin was implanted
into C57BL/6 female mice of 6 to 8 week old (Daehan Biolink Co.,
Ltd., Korea) by subcutaneous injection. To each mouse, 1.0 mg of
Horse chestnut extract of the Example 1 was orally administered
twice a day for four days. After five days, the Matrigel was recovered
from excised skin of each mouse and the amount of hemoglobin(Hb)
in the Matrigel was measured by Drabkin kit(Sigma Chemical Co.,
St. Louise, Mich., USA, Cat. No. 525), a reagent for determination
of total hemoglobin in blood.
[0115] As shown in FIG. 10 and Table 3, the average of total hemoglobin
levels in the Matrigel from Horse chestnut extract-treated group
were about 9.8% of that of the control group. That is, Horse chestnut
extract potently inhibited growth factor induced angiogenesis by
about 90% when it was administered orally.

Effect of other Anti-Angiogenic Extract on Tube Formation of HUVEC
[0116] The anti-angiogenic activity of Atractylodes japonica extract,
Artemisia capillaris extract, Vaccinium myrtillus extract, Houttuynia
cordata extract, and Paeonia japonica extract were also confirmed
by tube formation of HUVEC experiment prosecuted by the procedure
according to above Experimental Example 1. The inhibition of tube
formation by 50 .mu.g/Ml of each composition was 30-60% as compared
with non-treated control HUVEC. Percent inhibition by 50 .mu.g/Ml
of crude extract show 52% for Atractylodes japonica, 53% for Artemisia
capillaris, 40% for Vaccinium myrtillus, 30% for Houttuynia cordata,
and 38% for Paeonia japonica.

Experimental Example 4
Effect of Horse Chestnut Extract on Matrix Metalloproteinase Activity
[0117] (1) Preparation of MMP
[0118] MMP-2 and MMP-13 were cloned and prepared from insect cells
(Sf21 insect cell) by using a Baculovirus system.
[0119] MMP-2 cDNA (GENBANK No. XM.sub.--048244) was cloned to a
pBlueBac4.5 transfer vector (Invitrogen, Cat No. V1995-20), and
then transfected to Sf9 cells with a Bac-N-Blue Transfection Kit
(Invitrogen, Cat No. K855-01). Sf21 cells were incubated with a
TNM-FH (Sigma Co, St. Louis, Mo., U.S.A) media containing 10% fetal
bovine serum at 27.degree. C., then harvested and re-suspended at
a concentration of 10.sup.7 cell/Me. The cell suspension was incubated
with a virus containing the cloned gene for 1 hr at room temperature.
Infected Sf21 cells were grown for 72 hrs and the medium was recovered,
and the MMP-2 was purified with a gelatin-sepharose affinity column
from the recovered medium.
[0120] MMP-13 (GENBANK NO. XM.sub.--002427) was prepared from the
corresponding genes as previously described, and purified with SP-sepharose
chromatography.
[0121] (2) Inhibition of MMP Activity
[0122] In order to investigate MMP inhibition by Horse chestnut
extract, MMP enzyme activity was assayed by a spectrofluorometric
method (Perkin-Elmer LS50B).
[0123] Purified MMP-2 and MMP-13 were used after activation with
1 mM APMA before assay.
[0124] The substrate for MMP-2 was MCA-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH-
.sub.2 (BACHEM, Cat. No. M-1895), and MCA-Pro-Cha-Gly-Nva-His-Ala-Dpa-NH.s-
ub.2 was used as a substrate for MMP-13.
[0125] As a control, 10 nM MMP-2 and 10 .mu.M MMP-2 substrate were
mixed in 2 Ml of reaction buffer (50 mM Tricine (pH 7.5), 10 mM
CaCl.sub.2, 200 mM NaCl) in a 2 Ml cuvette. Fluorescence intensity
was measured for 5-10 min at room temperature with a spectrofluorometer
under an excitation wavelength of 325 nm and an emission wavelength
of 393 nm.
[0126] Horse chestnut extract (25 .mu.g/Ml) dissolved in water
and 10 nM MMP-2 were added to a reaction buffer containing a substrate,
and fluorescence intensity was measured in the same manner.
[0127] Activity for MMP-13 was also assayed, and fluorescence intensity
was measured as previously mentioned.
[0128] FIGS. 11 and 12 are diagrams of activity of MMP-2, and MMP-13.
The inhibition of MMP-2 and MMP-13 by Horse chestnut extract was
77% (FIG. 11) and 85% (FIG. 12), respectively.
[0129] As mentioned previously, Horse chestnut extract of the present
invention inhibits angiogenesis and matrix metalloproteinase activity.
Based on such results, Horse chestnut extract can be used for prevention
and treatment of angiogenesis- and/or MMP-dependent diseases.
Experimental Example 5
Inhibition of MMP-1 and -13 Activities by Horse Chestnut extract
in periodontal tissue.
[0130] The activities of matrix metalloproteinases (MMP) such as
MMP-1, -13, -9 in the periodontal tissue is highly induced in periodontitis
as a response to persistent bacterial infection, which is the most
common cause of adult tooth loss. Collagenases (MMP-1, -8, -13)
play major role in destruction of type I collagen matrix of periodontal
ligaments and alveolar bone, that results in deeper pockets and
bone loss.
[0131] Therefore, MMP inhibitors may be applied for periodontal
disease to stop further damage and progression of the disease by
blocking the breakdown of tissue and bone.
[0132] The inhibitory activity of Horse chestnut extract was compared
with doxycycline, well-known commercial MMP inhibitor in casein
zymogram. As shown in FIG. 13 the inhibitory effect of Horse chestnut
extract on MMP-1 and MMP-13 activities is similar or greater than
that of doxycycline.
[0133] Experimental Periodontitis was induced in adult male Sprague-Dawley
rats (350-370 g) by injecting LPS endotoxin(Sigma Chemical). Under
anesthesia each rat received three injections given every other
day at 3 injection sites per animal. Injections were made into the
anterior maxillary labial and palatal incisor gingivae. For control
groups gingiva were injected with PBS or LPS and each rat was orally
administered with vehicle, saline alone. For treatment group gingiva
were injected with LPS and each rat was orally administered with
12.5 mg/kg of Horse chestnut extract and 12.5 mg/kg of Melissa leaf
extract in saline daily. It is understood that the amount of Horse
chestnut extract used may vary according to the individual subject,
and therefore, the invention is not limited to the amount exemplified
herein. The amount used may be from about 2 to about 50 mg/kg.
[0134] On day 7, after euthanasia the gingival tissues from the
anterior maxillary labial and palatal incisor gingivae were removed
to measure the MMP activity. 100 mg of the gingival tissues were
extracted with 5 ml of 5M urea buffer at 4.degree. C. and the extract
was concentrated with Amicon Ultra centrifugal filter (MW cut off
10,000, Millipore) for gelatin zymogram analysis. As shown in FIG.
14, oral administration of both Horse chestnut extract and Melissa
leaf extract reduced proMMP-9, proMMP-2 and activated MMP-2 that
were highly increased in LPS-induced periodontitis gingivae. The
total MMP activities were decreased by oral administration of Horse
chestnut extract and Melissa leaf extract. Therefore, the composition
containing Horse chestnut extract can be administered orally to
patients or can be included in mouth wash or tooth paste to treat
or prevent periodontal disease.
