Description

Composition for Treatment of Brain Cancers and Functional Food Comprising Extract of Olibanum}

The present invention relates to a novel use of frankincense extract. Specifically, the present invention relates to a therapeutic composition and a functional food containing frankincense extract as an active ingredient, which exhibits excellent prophylactic or therapeutic efficacy against brain cancer.

Among the major diseases of modern people, researches on the treatment and diagnosis of cancer are being conducted mainly on lung cancer, liver cancer, and stomach cancer, which have high incidence. However, studies on brain cancer, esophageal cancer, colon cancer, pancreatic cancer, etc., which have a low incidence, are relatively poor. Clinical symptoms of brain cancer include headache, epileptic seizures, vomiting, motor paralysis, overlapping objects, poor vision, hormonal abnormalities, hearing loss, dizziness, and speech disorders.

"Brain cancer" refers to abnormally increased proliferation of any type of neuron, also referred to as primary brain cancer, or any other cancer that metastasizes to the central nervous system (CNS), also referred to as brain metastasis. For example, most neurons that are cells found in or containing the CNS, including neurons, microglia, and astroglia, are "finally differentiated", meaning that they no longer have the ability to complete the cell cycle. Kornblith et al, (1986), Cancer: Principles and Practice of Oncology, 2nd Ed., DeVita, V., Hellman, S., Rosenberg, S, eds., JB Lippincott Company, Philadelphia, Chapter 41: Neoplasms of the Central Nervous System). Even if neurons enter the cell cycle, they are usually unable to complete the process because they are apoptotic (cell death) (Multani, A.S., et al, Neoplasia 2 (4), 339-45 (2000)). Primary brain cancer can only occur in those cases where the nerve cells lose their protective ability to undergo apoptosis. Examples of primary brain cancers include, but are not limited to, neuroma, astrocytoma, neuroblastoma, glioma, meningioma, oligodendrocyte, stromal blastoma, spinal cord tumor and neuromyoma.

Gliomas comprise about 60% of all primary CNS tumors and typically occur in the cerebral hemispheres of the brain, but can be found in other areas such as the visual nerve, brain stem or cerebellum. Gliomas can be classified into groups according to the type of glial cell from which they originated (Kornblith et al, (1986), Cancer: Principles and Practice of Oncology, 2nd Ed., DeVita, V., Hellman, S., Rosenberg , S, eds., JB Lippincott Company, Philadelphia, Chapter 41: Neoplasms of the Central Nervous System). The most common type of glioma is astrocytoma. These tumors develop from star-shaped glial cells called astroglia. Astrocytes are assigned a rating according to their malignancy. Low-grade astrocytomas, also known as grade I and II astrocytomas, are minimal malignant, grow relatively slowly, and can often be completely eliminated using surgery. Mid-grade astrocytoma, also known as grade III astrocytoma, grows faster and is more malignant. Grade III astrocytoma is treated with radiation and some chemotherapy following surgery. High-grade astrocytoma, also known as grade IV astrocytoma, grows rapidly, invades nearby tissues and is very malignant. Grade IV astrocytomas are usually treated with a combination of radiation and chemotherapy following surgery. Glioblastoma multiforme is a Grade IV astrocytoma, which is the most malignant and lethal primary brain tumor (Id). When the same surgical techniques and principles are applied to treat glioblastoma multiforme and less malignant brain tumors, complete elimination of glioblastoma multiforme tumors is more difficult to achieve.

Malignant differences are also reflected in the prognosis for patients with primary brain tumors. Patients treated for grade I astrocytomas can usually survive for at least 10 years without recurrence, while the average survival for patients with grade IV astrocytoma tumors is 15 weeks after surgical treatment. Because of the high-malignant growth potential of grade IV astrocytoma tumors, only 5% of patients survive for 1 year after surgery alone and have nearly 0% survival after 2 years. Radiation therapy combined with surgical treatment increases survival by about 10% after two years of treatment, but virtually no patients survive for more than five years.

While therapies of surgery, radiation therapy and chemotherapy provide an opportunity for a moderately increased lifespan for patients with grade IV astrocytoma brain tumors, there are many risks associated with each treatment method. The benefit of treatment is minimal, and treatment can significantly reduce the quality of the patient's short-lived life. Thus, in particular, since CNS tumors represent the most common group of solid tumors in young patients, there is a clear need in the art for primary brain cancer prevention and treatment methods that overcome the disadvantages of the above-mentioned conventional approaches. Brain tumors are a secondary-induced cause of cancer-related death in infants, with approximately 25% of all such deaths, with current therapies in which most of these infants die within the first year of diagnosis.

Compared with primary brain tumors, the number of occurrences of brain metastases is much higher. Approximately 100,000 patients have symptomatic intracranial metastases in the United States each year, and one quarter of cancer patients have tumor metastasis according to autopsy studies (Newton, HB, et al, J. Neurooncol. 61, 35-44 ( 2003). Brain metastasis results from primary tumors elsewhere in the body, including, but not limited to, for example, lung cancer (both small and non-small cell), breast cancer, colorectal cancer, prostate cancer, melanoma and pancreatic cancer. Particularly in patients with metastatic breast cancer, the incidence of brain metastasis is diagnosed at a rate of 10-20% (Tyson, R.M. et al, Therapy 3 (1), 97-112 (2006)). Breast cancer is the second leading cause of cancer-related death in women, and nearly all deaths from breast cancer are due to metastatic disease with brain metastases found in 30% of patients at autopsy.

Standard modes of treatment include surgical resection, chemotherapy and radiation therapy, in particular whole-brain radiation therapy (WBRT) and stereotactic radiosurgery or combinations thereof. Surgery for brain metastases can improve survival, especially in patients with a single lesion. Surgery, however, may not be possible in terms of multiple lesions, lesions that are difficult to surgically approach, or inability to withstand surgery. In breast cancer, 50% of patients with brain cancer metastases have multiple metastases, making them less suitable as surgical candidates. WBRT can improve intermediate survival over untreated and as an adjuvant for surgery, which reduces the chance of relapse and dying nerve death, but does not change survival or level of action. SRS provides a method for treating brain metastases that cannot be surgically resected by location or patient symptoms. SRS provides an improvement in quality of life but does not provide survival benefits, except for patients with a single metastasis. The use of chemotherapy in the treatment of brain metastases is hampered by the impossibility of high molecular weight compounds, limiting most chemotherapeutic agents across the blood brain barrier. This is reflected in the fact that chemosensitive tumors, such as most metastatic breast carcinomas, often exhibit a complete systemic response to chemotherapy simultaneously with tumor progression in the brain. However, this initial resistance to the use of chemotherapy in the treatment of brain metastases has recently changed based on observations in animal models and human brain tumor autopsies, and metastatic lesions cause blood brain barrier insufficiency, whereby chemotherapy Drugs can always enter the tumor. Radiation therapy combined with chemotherapy has evolved from a first-line approach in the treatment of brain metastases.

However, there are serious risks and limitations associated with all current methods of treatment. Radiotherapy in attempts to deliver highly destructive doses of ionizing radiation, often through highly normal tissues of the body, preferably to highly specific and often incompletely defined areas of cancerous tissue, is first and foremost a cause of memory loss and personality deformation. Because of the disruption of the normal nervous system or other tissues it is severe and can have significant side effects. Chemotherapy in attempts to kill cancer cells in place of normal cells, preferably through the administration of other types of chemical agents or drugs to the tissues of the body, is limited in efficacy by the currently available chemical agents and is not intended to be toxic and intentional. May cause side effects. Surgery in an attempt to mechanically disrupt or hinder the progression of cancer can also cause serious side effects or consequences as a result of mechanical trauma or destruction of normal tissue. Some problems associated with the above approaches include (i) deleterious side effects, including alteration of intelligence, learning ability, memory, motor skills, consciousness and emotions; (Ii) recurrence of tumors within 3 to 5 years of treatment because of the development of resistance to these therapies; (Iii) death due to ineffectiveness of such treatment. From the foregoing, it will be apparent that there is an urgent need to develop a chemotherapeutic agent that can cross the blood brain barrier in an effective amount to reduce neoplastic expansion and / or growth of cancer in the central nervous system, which is not yet satisfied.

Brain cancer is a generic term for primary brain cancer that develops in the brain tissue and the envelope that surrounds the brain, and secondary brain cancer that has metastasized from cancer that occurs in the skull or other parts of the body. Such brain cancers are often distinguished from cancers occurring in other organs. First, lung, stomach, and breast cancers occur in one or two types of organs, and their properties are the same and similar. But the brain develops a wide variety of cancers. For example, glioblastoma multiforme, malignant gliomas, lymphomas, germ cell tumors, metastatic tumors, and the like.

Among these, glioma, especially glioblastoma multiforme (GBM), is the most malignant and aggressive disease, and has a very poor prognosis. The average survival time after diagnosis is very deadly. Since the boundary between brain cells and tumor cells is not clear, it is almost impossible to completely remove the GBM surgically.

Therefore, while the development of chemical therapeutics other than surgical treatment is urgently needed, effective treatments have not been developed yet, and research and development thereof are required.

Hereinafter, the present invention will be described in more detail based on the following examples. It should be noted, however, that the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention. The present invention is not limited to the following examples. Will be apparent to those skilled in the art to which the present invention pertains.

Example 1 Preparation of Frankincense Extract

3 kg of frankincense (Chinese) purchased from Seoul medicinal herb was dried and ground for 5 days at the shade and room temperature. The ground frankincense was immersed in 30 L of 95% ethanol and extracted at 50 ° C. for 24 hours. It was filtered through filter paper, dried and concentrated under reduced pressure at 45 ° C. to obtain 488 g of the total extract, which was stored at −20 ° C.

Example 2 Effect of Frankincense Extract on the Growth of Brain Cancer Cells

In order to determine the effect of the frankincense extract extracted in Example 1 on the growth of brain cancer cells, Alamar Blue analysis was performed on U-87 MG human brain cancer cells. The Alamar Blue assay is a modified form of the MTT assay, in which a specific enzyme degrades a living cell and then measures the fluorescence intensity of the product as the compound breaks down to determine the relative number of living cells after treatment. I am an experimental method. It will be described in more detail below.

<2-1> Preparation and Processing of Human Brain Cancer Cell Lines

U-87 MG cells, a brain cancer cell line used in the present invention, were distributed from the Korean Cell Line Bank (KCLB) and used for experiments. MEM (Minimal Essential Medium) containing 10% FBS (fetal bovine serum, fetal bovine serum) (Welgene) and 25 mM HEPES (4- (2-hydroxyethyl) -1-piperazineethanesulfonic acid) Cultured in the medium. The cells were maintained at 37 ° C. with 5% CO 2 water and passaged for 2-3 days.

<2-2> Cell growth inhibition measurement of U-87 MG cells

The frankincense extract extracted in Example 1 confirmed the cell growth inhibitory effect on U-87 MG brain cells. Specifically, the frankincense of 8.0 X 10 ³ U-87 MG cells per well in a 96 well plate and dissolved in dimethyl sulfoxide (DMSO) When the ethanol extract was treated at concentrations of 0 to 100 μg / ml (specifically, concentrations of 0, 3.125, 6.25, 12.5, 25, 50, and 100 μg / ml, respectively) for 48 hours, the degree of inhibition of cell growth was confirmed. (Table 1). After treatment with each concentration of extract, 20 μl of Alamar Blue reagent was added to 0.2 ml of cell culture filled in each well in a 96-well plate, and the plates were incubated for 2 hours in an incubator. The plate was slowly shaken to evenly react the cells in each well, and the intensity of fluorescence was measured by a Fluorescence Microplate Reader (Molecular Devices Corp.) at 590 nm while irradiating irradiation light at a wavelength of 544 nm. The viability of the cells is shown in FIG.

Frankincense concentration Brain cancer cell survival rate (average) Standard Deviation 0 μg / ml 1,000 0.000 3.125 μg / ml 1.009 0.054 6.25 μg / ml 0.998 0.056 12.5 μg / ml 1.058 0.068 25 μg / ml 1.090 0.095 50 [mu] g / ml 0.923 0.094 100 μg / ml 0.060 0.003

As a result, as shown in Table 1 and Figure 1, the higher the concentration of frankincense, the growth of brain cancer cells was reduced, from which it can be seen that frankincense has a brain cancer treatment effect. That is, brain cancer cells were killed at 0.2% at 6.25 µg / ml, 7.7% at 50 µg / ml, and 94.0% at 100 µg / ml. In addition, an EC ₅₀ (half maximal effective concentration) was determined to be 54.798 μg / ml. Table 1 describes the relative cell numbers of brain cancer cells after 48 hours according to each of the frankincense concentrations based on the number of survival rates of the brain cancer cells of the non-treated control group. As such, the frankincense extract of the present invention has excellent U-87 MG cell killing activity, further demonstrating that it has a therapeutic and prophylactic activity for brain cancer.

Example 3 Acute Toxicity Test with Frankincense Extract

The frankincense used in the present invention was widely used as a medicinal herb, so it was judged that there would be no problem in stability.

Acute toxicity test was performed using 6-week-old SPF SD rats. Two animals per group were suspended orally at a dose of 5 g / kg each of the frankincense extract of Example 1 of the present invention was suspended in 0.5% methylcellulose solution. After administration of the test substance, mortality, clinical symptoms, and changes in body weight were observed, and hematological and hematological examinations were performed.

As a result, there were no clinical symptoms or deaths in all animals treated with the test substance, and no toxicity change was observed in weight change, blood test, blood biochemistry test, autopsy findings, etc. As a result, all of the frankincense extract did not show toxic changes up to 5 g / kg in rats, and the minimum lethal dose (LD ₅₀ ) was determined to be a safe substance of 5 g / kg or more.

&Lt; Comparative Example 1 &

 Turmeric is a substance that shows anticancer activity against various kinds of cancers such as lung cancer, uterine cancer and breast cancer. The present inventors confirmed the effectiveness of the frankincense extract of the present invention by confirming the extent to which the turmeric affects the growth of brain cancer cells.

Specifically, 3 kg of turmeric (domestic) purchased from Seoul Herbal Medicine was dried and ground for 5 days at the shade and room temperature. The ground turmeric was immersed in 30 L of 95% ethanol and extracted at 50 ° C. for 24 hours. This was filtered through a filter paper, dried and concentrated under reduced pressure at 45 ° C. to obtain 474 g of a total extract, which was stored at −20 ° C.

The turmeric extract was confirmed the growth inhibition of the U-87 MG cells in the same manner as in Example 2, and the results are shown in Table 2 and FIG.

Frankincense concentration Brain cancer cell survival rate (average) Standard Deviation 0 μg / ml 1,000 0.000 3.125 μg / ml 1.020 0.076 6.25 μg / ml 1.042 0.097 12.5 μg / ml 1.060 0.092 25 μg / ml 1.021 0.081 50 [mu] g / ml 0.987 0.090 100 μg / ml 0.913 0.029

As a result, as shown in Table 2, turmeric hardly reduced the growth of brain cancer cells even when the treatment concentration was high.
