The present invention relates to a fractional extract of Melissa officinalis leaf and a novel pharmaceutical and a food composition comprising the same as effective component.
Melissa officinalis is an herbaceous perennial plant, which belongs to the Labiatae family, and is also nicknamed Lemon Balm.
A Melissa officinalis leaf extract contains flavonoids, triterpene acids, volatile oils, glycosides of the alcoholic and phenolic compounds and caffeic acid derivatives. In particular, the flavonoids contained in Melissa officinalis leaves are cynaroside, cosmosin, rhamnocitrin, isoquercitrin, etc., and ursolic acid as triterpene acid. A Melissa officinalis leaf extract contains hydroxycinnamic acid derivatives such as rosmarinic acid, one of non-volatile ingredients which has been attracting attention recently, and geraniol, neral, citronellal and eugenol as volatile oils.
Non-alcoholic steatohepatitis (NASH) is a disease in which fat accumulates in the liver, causing hepatocyte ballooning and inflammation, followed by fibrosis which can lead to liver cirrhosis, and to further complication such as liver cancer in some cases.
The number of patients with NASH is rapidly increasing, but the pathogenesis of the disease is not clear and various causes are at work, making it difficult to treat with one mechanism or control of the cause, and there is no approved drug.
NASH progresses chronically, so there are generally no specific symptoms, but liver functions gradually deteriorate, such as increased activity of alkaline phosphatase (ALP) or aminotransferase, which is a measure of liver function.
NASH progresses to liver fibrosis or cirrhosis if left unattended, resulting in poor prognosis. Thus, it is necessary to suppress fat accumulation in the liver and additional inflammation and fibrosis to prevent NASH from progressing to liver cirrhosis, but no such treatment is suggested. Therefore, there is a need to develop effective therapeutics that can treat NASH.
Non-alcoholic fatty liver disease (NAFLD) refers to a condition in which triglycerides are excessively accumulated in the liver regardless of alcohol intake. If the triglyceride content in the liver is above the top 95% among healthy and thin people, or the proportion of triglyceride particles in the cytoplasm within the liver cell is above 5%, it is defined as a simple fatty liver among non-alcoholic fatty liver disease (NAFLD). NAFLD has been reported to occur in 10-24% of the general population and 58-74% of obese people.
Angiogenesis is a process through which new capillaries form from pre-existing microvessels. Normal angiogenesis occurs during embryonic development, tissue regeneration and wound healing, and the development of the corpus luteum, which is a periodic change in the female reproductive system, and in these cases it is tightly regulated. [Folkman and Cotran, Relation of vascular proliferation to tumor growth, Int Rev Exp Pathol 16, 207-248(1976)].
In adults, the vascular endothelial cells grow very slowly and do not divide relatively well as compared with other types of cells. However, the angiogenesis in adults is provoked depending on the stimulation of angiogenesis-stimulating factors, the release of pro-angiogenic cytokines from inflammatory cells, and the activation of hydrolytic enzymes that release the angiogenic mediators sequestered within the extracellular matrix.
Generally, the process of angiogenesis is the degradation of basement membrane of blood vessels by proteases, the migration of vascular endothelial cells, and the lumen formation via proliferation and differentiation of endothelial cells. One of the major events in the process of angiogenesis is a breakdown of the basement membrane surrounding vessels by enzymes, and the most important enzymes of matrix degradation are those belonging to the family of Matrix metalloproteinase (MMP).
It is known that pathological angiogenesis takes place when the failure in the regulation of angiogenesis occurs or MMPs, important enzymes in angiogenesis are highly activated, which is associated with many diseases (Ref. Polverini P J, Critical Reviews in Oral Biology, 6(3), 1995, 230-247; Arup Das, et al., Progress in Retinal and Eye Research, 22, 2003, 721-748; Nick Di Girolamo, et al., IOVS, Vol. 42, No. 9, August 2001, 1963-1968; Patricia Lee, et al., Survey of ophthalmology, vol 43, No. 3, Nov-Dec 1998, 245-269; D.

An example of angiogenesis-related disease or MMP (Matrix metalloproteinase)-mediated disease is obesity in which excess fat accumulates in the body due to an imbalance in energy intake and consumption that can cause various health problems. The cause is most likely due to lifestyle such as excessive intake of nutrients and lack of physical activity, and in rare cases, it can occur secondary due to drug use or disease.
According to the World Health Organization (WHO) statistics of 2014, 1.9 billion adults over the age of 18 were overweight, of which 600 million people were obese worldwide. Obesity is one of the leading factors that increase the incidence of cardiovascular diseases, Type 2 diabetes and several types of cancer which lead to the death of more than 2.8 million people each year due to overweight or obesity.
As the living standards of people improve, obesity has become a global social problem. According to the National Health and Nutrition Examination Survey of 2015, the fat intake of Koreans increased by 5.9 g over the past 10 years, and the prevalence of obesity increased by 1.9% compared with 2005. In particular, the prevalence of obesity in men increased significantly to 39.7%, and the prevalence of hypercholesterolemia increased by 9.9% to 17.9%.
Several drugs have been developed to improve obesity, which are largely divided into appetite suppressants and fat absorption inhibitors according to their mechanism of action. However, drugs such as Phentermine and Diethylpropion that suppress appetite have side effects such as increase in blood pressure, dizziness, headache, tremor, and dry mouth. In the case of orlistat, a fat absorption inhibitor, the absorption of fat-soluble vitamins is inhibited, and has side effects such as steatorrhea, fat excretion, frequent defecation, and fecal incontinence.
Therefore, the need for the development of safe drug with fewer side effects to prevent or treat obesity has been raised.
Macular degeneration, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, is a disease that causes visual impairment due to degeneration by various causes in the macula lutea where the concentration of photoreceptor cells is very high and receives light most clearly and accurately. Macular degeneration is one of the three leading causes of blindness along with glaucoma and diabetic retinopathy. The biggest cause of macular degeneration is age and other causes are family history, race, and smoking. When the macular is damaged, the eye loses the ability to recognize details such as small print, facial features, or small objects.
There are two types of macular degeneration: non-exudative (dry) macular degeneration and exudative (wet) macular degeneration, and 90% of people with macular degeneration have the dry form. In dry macular degeneration, waste material collects under the macula, forming yellow deposits called drusen. The presence of drusen interferes with blood flow to the retina, particularly the macula, and when the blood flow is reduced, the supply of nutrients to the macula is reduced, thereby stopping or atrophying the efficient action of photosensitive cells. In wet macular degeneration, new weak blood vessels grow in or under the retina, causing fluid and blood to leak into the space below the macula.
Although macular degeneration was considered a disease that occurs frequently among the elderly, it is known that the number of patients in their 40s and 50s is increasing rapidly in recent years. Westernization of diet, such as the increase in fat intake, has been pointed out as one of the main reasons for the decrease in the age of onset of macular degeneration.
Lutein is a naturally occurring carotenoid that exists in a natural state without vitamin A activity, and is contained in large amounts in green and yellow vegetables. Lutein, one of the most abundant carotenoids in food products and human blood, is known to play a role in antioxidant effects and protecting plants from UV rays. For humans, it is known as the main constituent of the macula and lens of the eye, which plays an important role in improving eye health and vision.
However, a research team at the Moran Eye Center of the University of Utah reported in ‘JAMA Ophthalmology’, a journal of the American Medical Association, that a round, yellowish crystal-like substance was found inside the fovea of a woman who took an excessive amount of lutein for a long period. In the case of the patient above, it has been reported that she took 20 mg of lutein supplement on a daily basis for the last 8 years and that she also consumed lutein-rich foods such as spinach, broccoli, kale, and avocado. Therefore, the research team assumed that lutein precipitated in the eyeball, crystals were formed, and macular degeneration occurred.
Therefore, although lutein has an effect of improving vision in macular degeneration, side effects such as macular degeneration appear when consumed for a long period of time or in excess, so it is necessary to develop a method for preventing, alleviating or suppressing it.
Psoriasis, an example of angiogenesis-related or matrix metalloproteinase (MMP)-mediated disease, is a chronic inflammatory disease that is covered with white or silvery scales, and has a clear boundary of red papule or plate-like rash of various sizes repeatedly occurring on the skin of the body. It is a dermatologic disease characterized by epidermal proliferation and dermis inflammation histologically, which occurs at a frequency of 1 to 2% of the population. It is a chronic skin disease in which small millet-like rashes form on the skin and white dandruff-like dead skin cells build up on top of the rash. So, if they spread a lot, almost all the skin of the body is covered with rashes.
In psoriasis, as the number of skin cells that make dead skin cells increase rapidly, dandruff-like dead skin cells build up on top of the skin. The exact cause of psoriasis isn't fully understood, but it is thought to be an immune system problem and besides that, genetic factors, environmental factors, drugs, skin irritation, dryness, upper respiratory tract inflammation, mental stress, etc. are mentioned as factors that cause or worsen psoriasis.
Vitamin D analogues, narrow-band UVB treatment, Psoralen plus ultraviolet A (Bath-PUVA), and cyclosporine are used to treat psoriasis. There is still no known causative therapy for psoriasis. This is because the pathological cause of the disease is not clearly identified. Treatment methods such as vitamin D derivative ointment, narrow-band UVB treatment, bath-PUVA, and cyclosporin are only temporary symptom relief treatment, so they cannot be called causative therapy because psoriasis recurs.
Endometriosis, is an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, in which the endometrium or similar tissue occurs outside the uterus depending on the increase of estrogen. It is a benign disease that causes pain including menstrual cramps and decreases fertility, which leads to a significant decline in the quality of life for women in social and reproductive activities. In endometriosis, dysmenorrhea appears to be very frequent, and pain symptoms such as lower abdominal pain, back pain, dyspareunia, and defecation pain other than menstruation are also confirmed with high frequency.
Many patients with endometriosis recur or repeat recurrence until menopause unless radical surgery is performed, which requires long-term treatment and management. Drug therapy is often the first choice for the treatment of endometriosis. It is largely divided into symptomatic therapy and endocrine therapy. For symptomatic therapy, analgesic drugs are mainly used for improving the pain caused by endometriosis. For endocrine therapy, low-dose estrogen-progestin preparations, dienogest, and gonadotropin-releasing hormone (GnRH) agonists are used for suppressing estrogen-dependent endometrial proliferation in addition to pain relief.
However, it is said that pain associated with endometriosis cannot be controlled with analgesic drugs in 10% to 30% of endometriosis patients. Also, caution is required for thrombosis and liver dysfunction in the use of low-dose estrogen-progestin preparations. It has been reported that dienogest has a side effect of irregular genital bleeding of 71.9% in a long-term administration study and may lead to severe anemia. GnRH agonists cannot be administered for more than 6 months in principle due to the decrease of bone mineral density based on an estrogen-lowering action in some cases.
As described above, in drug therapy for endometriosis treatment, there are many patients who find it difficult to continue administration because it has been confirmed that each drug has its own side effect. Therefore, there is a demand for the development of a new drug that can be administered over a long period of time with reduced side effects.
Cancer, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)—mediated disease, is one of the most common causes of death worldwide. About 10 million new cases occur each year, accounting for about 12% of all deaths, makes it the third leading cause of death.
Among cancers, breast cancer is the most common malignant tumor in women that causes more than 40,000 deaths annually, and early diagnosis is very important. Despite the many known anticancer drugs, the survival rate has not improved if the cancer is very advanced or has metastasized
Chemotherapy, a representative anticancer therapy has been used as the most effective treatment for cancer when used by itself or in combination with other therapies. However, although the efficacy of anticancer drugs in chemotherapy depends on the ability to kill cancer cells, there is a problem that drugs can act not only on cancer cells but also on normal cells, requiring drugs to treat cancer efficiently.
Arteriosclerosis also called atherosclerosis, is an example of angiogenesis-related or matrix metalloproteinase (MMP)-mediated disease, in which the arteries harden due to thickening or tissue degeneration of the walls of the arteries. As the intima of the arteries thicken, the inner diameter narrows and disturbs the blood flow that supplies oxygen and various nutrients, leading to various diseases. Arteriosclerosis is likely to occur in the cerebral artery or coronary artery. In the case of cerebral arteriosclerosis, headache, dizziness, and mental disorders appear and cause encephalomalacia. In the case of coronary arteriosclerosis, it is known to cause pain and arrhythmia in the heart, causing angina pectoris and myocardial infarction. In addition, arteriosclerosis is deeply related to the occurrence and progression of diseases such as metabolic syndromes including truncal obesity, obesity (overweight), thrombosis, hypercoagulation, and thrombotic conditions (arterial and venous), or dyslipidemia. It also causes or exacerbates diabetic complications.
In addition, when the blood triglyceride concentration is increased due to obesity, hyperlipidemia, etc., macrophages are converted into foam cells, or the rate of death increases by triglycerides. Thus, as macrophages die, their immune function and triglyceride metabolism function are lowered, which lowers the removal function of the foam cells, increasing the possibility of developing or worsening arteriosclerosis. Therefore, to prevent the onset or exacerbation of arteriosclerosis, it is important to ensure that macrophages maintain their function of removing foam cells or to minimize death by triglycerides even when blood fat concentration is high.
Currently, statin-based drugs such as rosuvastatin and simvastatin are mainly used for the treatment of arteriosclerosis, but it is known that it has a side effect of reducing the activity of macrophages that remove foam cells. In addition, statin-based drugs have been pointed out as a problem in that they cause side effects such as diabetes, muscular dystrophy, and hyperglycemia, so there is a need for research on natural products with fewer side effects.
Arthritis, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, is largely divided into rheumatoid arthritis and osteoarthritis (degenerative arthritis). Rheumatoid arthritis is a chronic, inflammatory, multisystem disorder that typically involves the joints. Symptoms include pain and swelling with inflammation of various joints such as fingers, hands, feet, wrists, ankles, and knees, and also cause abnormalities in various organs such as muscles, skin, lungs, and eyes. Genetic factors, pathogenic infections, and immune abnormalities have been suggested as the causes of arthritis but they are not precisely known.
As for the pathogenesis, due to hypersensitivity to autologous or foreign antigens interlerkin-1 (IL-1), tumor necrosis factor (TNF), prostaglandin E2 (PGE2), collagenase, proteinase, substance-P, etc. released from immune cells reduce cartilage and collagen, and induce the proliferation and inflammation of synovial fluids, which eventually leads to destruction of cartilage and bone.
Osteoarthritis refers to a degenerative condition of the synovial joint and is also called degenerative arthritis. It is a disease that occurs in middle-aged or old ages as a phenomenon of aging and causes movement disorders after the age of 65. The main causes are thought to be caused by obesity, hyperkinesia syndrome, recurrent dislocation, recurrent hemarthrosis, internal joint dislocation, inflammatory arthritis, and gout, etc.
Osteoarthritis is mainly involved in progressive damage of the articular cartilage. As arthritis progresses, the production of inflammatory cytokines such as tumor necrosis factor-α (TNF-α), and interleukin-1β(IL-1β), and nitric oxide (NO), etc., increase which causes severe pain in tissues of muscles, tendons, and ligaments.
The treatment methods for arthritis currently used are largely divided into non-pharmaceutical treatment, drug treatment, and surgical treatment. Non-pharmaceutical treatment methods include reduction of joint load, patella fixation, heat treatment, and exercise. Drug treatment includes oral medications and intra-articular injections. The drugs used in initial treatment are non-steroidal anti-inflammatory drugs (NSAIDs). Although these NSAIDs simply reduce pain and relieve symptoms, they cannot prevent joint cartilage loss or disease progression. When taken for a long time, it may cause heartburn and gastric bleeding due to side effects of gastrointestinal tract, kidney, heart, and liver as well as blood clotting mechanisms. Therefore, there is a need for research on natural products with fewer side effects.
Inflammatory bowel disease (IBD), an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, causes chronic inflammation or ulceration in the mucous membranes of the large intestine and small intestine, and it is an incurable disease in which diarrhea and bloody stools continue and recur in the long-term.
Inflammatory bowel disease is a more common disease among Westerners, but it has been increasing rapidly in Korea since the 1980s. The prevalence of IBD is 15-35 years old and is reported by all age group, of which 15% are over 60 years old, and about 15% of IBD patients have a family history in an immediate family.
Although the exact etiology of inflammatory bowel disease is still unclear, inflammatory mediators and the activation of immune cells are presumed to be important etiologies due to autoimmune diseases along with environmental or genetic factors.
Inflammatory bowel disease is classified into two conditions, ulcerative colitis and Crohn's disease, which are clinically similar but differ from each other in histological, endoscopic and immunological aspects. Inflammatory mediators and the activation of immune cells are known to be an important etiology for this disease.
The persistent or inappropriate activation of the intestinal immune system plays an important role in the pathophysiology of chronic mucositis inflammation, and in particular, infiltration of neutrophils, macrophages, lymphocytes and mast cells eventually leads to mucosal destruction and ulceration.
In the course of the pathogenesis of inflammatory bowel disease, inflammatory cytokines such as TNF-α (Tumor necrosis factor-α), interleukin-6 (IL-6) and interleukin-8 (IL-8) play a major role.
In particular, TNF-α is highly expressed in the colon lumen and colonic epithelial cells of ulcerative colitis patients, and according to recent studies TNF-α is known to play an important role in the pathogenesis of ulcerative colitis. Infliximab, an anti-TNF-α antibody, is known to be effective in the treatment of Crohn's disease which was incurable. However, these treatments are expensive and cause side effects such as fluid reactions or infectious complications in some patients.
Current treatments for inflammatory bowel disease use 5-aminosalicylic acid (5-ASA) drugs that block the production of prostaglandins such as sulfasalazine, mesalazine or immunosuppressants of steroids. In case of not responding to steroid treatment immunosuppressants such as azathioprine, 6-mercaptopurine, and cyclosporine are also used, but there is no drug that can be expected to cure.
Alzheimer's disease, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, is the most common cause of dementia which accounts for about 60 to 80% of dementia. About 33.9 million people worldwide have Alzheimer's disease, and after 40 years, the prevalence is expected to triple with increasing life expectancy. Currently, there is no drug that can be expected to provide a clear improvement in Alzheimer's disease, and since the onset of the disease goes through a process of worsening for several decades, research around the world is attracting attention on the prevention of the Alzheimer's disease.
Alzheimer's disease is known to be caused by a complex interaction of various risk factors. Along with genetic risk factors, demographic risk factors such as age, sex, and educational background and environmental risk factors such as smoking, drinking, nutrition and social activity are known so far. Representative genetic markers for Alzheimer's include apolipoprotein E (APOE) ε4, but these genetic markers are not altered or modified. However, acquired factors (e.g., vascular risk factors, lifestyle) are modifiable factors, and thus, in addition to studies investigating how these modifiable factors regulate the onset of dementia, it is possible to reduce or delay the onset of dementia by inversely regulating these factors.
Among Alzheimer's treatment drugs, Memantine was developed in the 1980s by Merz Pharmaceuticals in Germany as a treatment for Parkinson's disease and movement disorders and also has been marketed as a treatment for dementia in Germany. As a study result was announced in 1999 that it was effective in treating severe Alzheimer's disease, it was approved as a treatment for Alzheimer's disease in Europe in 2002. In October 2003, it was approved by the US FDA as a treatment for moderate to severe Alzheimer's disease. Recently, it is also marketed as EBIXA® by Lundbeck in Korea. Evixa commercially available contains memantine hydrochloride in tablet or liquid form, and its administration is made within a range that does not exceed the maximum required dose of 20 mg per day in consideration of both efficacy and tolerability.
Memantine's mechanism of action is to block glutamate, an excitatory neurotransmitter. Glutamate overstimulates the nerves in the brain and causes excessive calcium influx into the cranial nerve cells, causing damage and death of the cranial nerves and memantine is known to prevent this. It is known that the calcium ion channel of the NMDA receptor is always opened even during the resting phase due to excessive secretion of glutamate in Alzheimer's patients, resulting in excessive calcium influx into the cell, which is associated with the death of cranial nerves. Memantine blocks the influx of calcium into cells by acting as a low-affinity antagonist in the calcium channel located at the center of the NMDA receptor. It reduces the excessive excitability of nerve cells due to excessive calcium influx into cells and when physiological actions such as memorization and learning are needed, it exits the calcium channel and causes depolarization to occur normally so that it stabilizes physiological nerve signals to normalize the function of nerve cells.
However, as side effects of memantine, loss of appetite, diarrhea, weight loss, dry mouth, dizziness, sleep disturbance, and fatigue, etc. have been reported. In addition, it has been reported to rarely cause dizziness, headache, constipation, drowsiness, and high blood pressure. Therefore, there is a need for research on natural products with fewer side effects.
Periodontal disease, an example of angiogenesis-related disease or -matrix metalloproteinase (MMP)-mediated disease, is a type of inflammation that occurs in supporting tissues around teeth by toxins which are metabolites of microorganisms living in the oral cavity. These periodontal diseases start from gingivitis in the early stages, and if left untreated, gingivitis develops into periodontal disease accompanied by swelling of the gums, bleeding and severe bad breath. In addition, persistent periodontal disease develops into progressive periodontal disease in which collagen supporting the periodontal membrane is destroyed and the alveolar bone supporting the teeth is dissolved, the periodontal ligaments are separated to form a periodontal pocket which can damage the teeth in severe cases.
The etiology of periodontal disease is different depending on gender, race, and age. This periodontal disease worsens for several years and repeats a lulled state as the infection state continues. Its incidence rate is high in patients with systemic diseases such as diabetes, AIDS, neutropenia, and Down's syndrome.
The most effective method for preventing periodontal disease can be achieved by using a substance that inhibits the activity of these microorganisms and facilitates blood flow to the inflamed gums. However, among the drugs used for the prevention and/or treatment of periodontal disease, antibiotics such as penicillin, erythromycin, and tetracycline are effective in sterilization and growth inhibition, but have serious side effects such as causing the emergence of resistant bacteria. In the case of antibacterial agents like chlorhexidine, it has an effect of inhibiting the formation of caries, but can be a problem because of strong toxicity. Therefore, there is a need for research on natural products with fewer side effects.
Diabetic retinopathy, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, is more specific for hyperglycemia than other chronic diabetes-related complications.
Depending on the degree of progression, diabetic retinopathy can be divided into early non-proliferative diabetic retinopathy (NPDR) and late proliferative diabetic retinopathy (PDR). In addition, when accompanied by diabetic macular edema (DME), severe visual impairment may be seen even at this stage.
If diabetic retinopathy is detected early, proper management can prevent the progression and worsening of retinopathy, but if the condition is not properly managed, it can lead to severe vision loss or blindness. Currently, diabetic retinopathy is considered a major cause of blindness in adults, and despite its clinical significance, drugs for preventing or treating diabetic retinopathy is not being actively developed.
Therefore, the need for drug development for preventing or treating diabetic retinopathy has been raised.
Sjogren's syndrome, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, is a chronic disease that causes secretion disturbance due to the invasion of lymphocytes into exocrine glands. The characteristic symptoms of this disease are dry eye and dry mouth caused by lymphocytic infiltrates in the lacrimal and salivary glands. With the loss of tears and saliva, characteristic changes in the eye (called aqueous lacrimal deficiency or keratoconjunctivitis sicca) and characteristic changes in the oral cavity (this results in damage to teeth, increase in oral infections, difficulty of swallowing, and mouth sores) may cause pain. The patient may also have joint inflammation (arthritis), muscle inflammation (myositis), nerve inflammation (neuropathy), thyroid inflammation (thyroiditis), kidney inflammation (nephritis), lung inflammation, or inflammation of other parts of the body, or lymph nodes swelling. Also, patients may experience fatigue and sleep disturbances. Sjogren's syndrome mainly affects middle-aged women.
Currently, there is no known treatment for Sjogren's syndrome or an effective treatment to restore glandular secretion. Conventional treatment is usually symptomatic and supportive which includes rehydration therapy (e.g. to relieve symptoms of dry eyes and mouth) and various forms of lubrication. Prescription medications are available, including cyclosporine that helps treat chronic dry eye, and cevimeline or pilocarpine that helps stimulate flow of saliva. Anti-inflammatory agents such as methotrexate and hydroxychloroquine have also been prescribed for amelioration of musculoskeletal symptoms. However, none of the currently available drugs are ideal due to the wide range of serious side effects.
Glaucoma, an example of angiogenesis-related disease or matrix metalloproteinase (MMP)-mediated disease, is a disease in which the optic nerve-responsible for transmitting visual information to the brain is damaged, that makes the optic nerve atrophied and field of view is narrow. As types of glaucoma, primary open-angle glaucoma (POAG), normal tension glaucoma, primary angle-closure glaucoma, developmental glaucoma, secondary glaucoma are known. In addition, although visual field is normal, ocular hypertension, a condition in which intraocular pressure is chronically high, is one of the risk factors for glaucoma.
In the treatment of glaucoma, lowering the intraocular pressure and preventing further visual field disturbances are considered the top priority, and drug treatment, laser treatment, and surgery are performed to lower the intraocular pressure, but these conventional treatments are not satisfactory to all patients. There is a demand for a glaucoma treatment drug containing an active ingredient with a new mechanism of action or a new structure that is not found in existing therapeutic drugs.

The therapeutic effect of the fractional extract of Melissa leaf according to the Example on non-alcoholic steatohepatitis was evaluated in a methionine/choline deficient high-fat diet animal model.
The study was conducted using C57BI/6 mice fed methionine/choline deficiency high-fat diet (MCD-HFD), which were divided into the treatment group administered with the fractional extract of Melissa leaf according to the Example, and the control group administered with 0.5% CMC.
For the administration method, while feeding the MCD-HFD, the fractional extract of Melissa leaf according to the Example was orally administered once a day at a dose of 200 mg/kg, and to the control group 0.5% CMC was administered at the same time. The administration period was for 9 weeks. In the normal group, non-alcoholic steatohepatitis was not induced by feeding the normal diet.
To confirm the degree of fibrosis in the liver, Picrosirius red staining was performed on liver tissue. For picrosirius red staining, liver tissue samples fixed in 10% formalin were embedded in paraffin, cut into 5 μm sections, and the tissue sections were incubated in 0.5% thiosemicarbazide for 10 minutes. Then, it was stained with 0.1% Sirius Red F3B in saturated picric acid for 1 hour and then washed with 0.5% acetic acid solution. To observe myofibroblasts which are the marker of liver fibrosis, immunohistochemical tests were performed using an alpha-smooth muscle actin (alpha-SMA) antibody. Paraffin-embedded liver tissue was cut into 4 μm sections, attached to a slide glass treated with poly-L-lysine, deparaffinized, and sequentially immersed in ethanol. After 10 minutes of treatment in 3% H2O2/methanol solution to remove endogenous peroxidase, it was reacted with normal goat serum in a moisture chamber for 40 minutes to eliminate non-specific reactions, and then washed with a 0.01 M phosphate-buffered saline solution (PBS, pH 7.4) containing 0.05% non-fat dry milk and 0.3% Triton X-100. The primary antibody was reacted for 1 hour, respectively, and the secondary antibody was reacted for 60 minutes, followed by color development. Western blot was performed to confirm the protein expression levels of Col1A2, TGF beta, IL-6 and IL-10. Specifically, liver tissue was dissolved in a buffer containing a protease inhibitor cocktail, and then the protein was extracted. After the extracted protein was quantified using a BCA assay kit, it was mixed with SDS gel loading buffer, and boiled at 100° C. for 5 minutes for denaturation. Proteins electrophoresed on SDS-PAGE gel were transferred to a nitrocellulose membrane, and then the membrane was left in 5% skim milk for 1 hour to block non-specific protein binding. A general immunoblot was performed by treating antibodies of Col1A2, TGF beta, IL-6, IL-10 and beta-actin as primary antibodies, and then the intensity of the band finally appeared was measured with gel documentation software and graphed.
