Description

TECHNICAL FIELD The present invention relates to a composition for preventing and treating obesity and / or lipid-related metabolic diseases, which comprises dihydroartemic acid or a pharmaceutical, cosmetic or pharmacologically acceptable salt thereof as an active ingredient. lipid-related metabolic disease comprising dihydroartemisinic acid or pharmaceutically, cosmetically or food acceptable salt thereof as an active ingredient}

The present invention relates to a composition useful for the prevention and treatment of obesity and / or lipid-related metabolic diseases, including dihydroatomic acid or its pharmaceutical, cosmetic or pharmacologically acceptable salts.

According to the World Health Organization (WHO) data released in September 2006, there are about 400 million people in the world over the age of 15 who are classified as obese, and over 1.6 billion people are overweight. According to this trend, obesity is becoming a serious social problem, not a simple disease of an individual.

Obesity is a chronic disease that occurs when excess calories are consumed in excess of the calories consumed, resulting in the accumulation of extra calories in the body in the form of fat, or the ability to control energy balance due to lapatin resistance and insulin resistance. , JAMA, 282, 1999), which is a strong risk factor for ischemic heart disease and cerebrovascular disease (Kopleman PG, Nature, 404, 2000; Manson et al., New England J. Med., 333, ).

The causes of obesity are known to be caused by genetic influences, environmental effects of westernized eating habits, and psychological effects due to stress, but the precise cause and mechanism of obesity is unclear.

In addition, fat stored in adipocytes is used as an important energy source in the body, but as the obesity proceeds, the number of adipocytes is increased and the adipocyte differentiation is achieved. Fatty cell differentiation leads to increased triglyceride (triglyceride) synthesis. Neutral fat stored in fat cells increases the size of adipocytes, which can grow up to about 20 times in diameter depending on fat storage, resulting in a cell volume increase of several thousand times. However, since the process of differentiation of new precursor adipocytes into adipocytes is ineffective in controlling diets, in order to control the fundamental treatment or inhibition of obesity, the differentiation process of adipocytes Is important.

The goal of treating obesity, which is caused by such causes and effects, can be divided into two major categories. The first is to burn excess fat to reduce body weight, and the second is to improve metabolic imbalance. Currently, obesity treatment aims not only to lose weight, but also to improve metabolic abnormalities by eliminating factors that cause early cardiovascular disease. In addition, studies to suppress obesity through controlling dietary intake and energy consumption have been actively conducted. The hypothalamus, especially the hypothalamus, plays an important role in the pathogenesis of obesity. Neuropeptide Y, POMC / CART, melanocyte, melanocyte, Cholinesterase, norepinephrine, serotonin, etc. are secreted from the hypothalamus. Current strategies for the development of obesity therapies are such as reducing food intake, inhibiting the absorption of heat, promoting exothermic reactions, regulating energy metabolism, and regulating signaling through the nervous system (MJ Jung, J Pediatr 48 (2), 2005).

The most common drugs include Xenical (Xenical ^TM, Roche Pharmaceuticals, Switzerland), rideoktil (Reductil ^TM, Abbott, USA), exo Rize (Exolise ^TM, Ato Pharma, France), etc. Although heart disease among known obesity treatment so far , Respiratory diseases, and neurological diseases, and the persistence of its efficacy is low, so that the search for anti-obesity substances having safer and superior efficacy is proceeding.

Dihydroartemisinic aicd is a precursor of Artemisinin, a typical anti-malarial drug derived from Artemisia annua L , and may be isolated from mugwort or produced by microbial culture. Dihydro athemic acid has been actively studied for its role as a precursor in the production of atemicinin and it has been known that atemicinin has the efficacy of antimicrobial, anti-cancer, anti-obesity, anti-inflammatory effects (Galal AM et al , J Nat Prod, 68 (6), 2005, Sun WC et al., Zhongguo Yao Li Xue Bao, 13 (6), 1992).

To differentiate into adipocytes, cells were seeded on a 12-well microplate at a rate of about 90%, and then cultured for another 2 days. MDI (0.5 mM of isobutylmethylxanthin, 1 μM of dexamethasone, 1 μg / mL of insulin) was treated with a cocktail Respectively. After 3 days, the medium was replaced with medium containing insulin (insulin 1 μg / mL), and after 3 days, it was replaced with DMEM medium supplemented with 10% FBS. The MDI cocktail was treated with 10, 25, and 50 μM of dihydroatheximinic acid from the point of induction of differentiation, and then reprocessed at the same concentration every time the culture medium was changed. The amount of fat accumulated in the differentiated cells was stained with Oil RedO staining method, dissolved in isopropyl alcohol, and then measured for optical density at 540 nm. The results are shown in Fig. 1 and Fig.

As a result of experiments, it was confirmed that MDI treatment of immature adipocyte 3T3-L1 induces differentiation into adipocytes and accumulation of intracellular lipids. The result of measurement of absorbance by dyeing with oil red O-1 showed that the concentration of dihydroatomic acid And the inhibition of adipocyte differentiation was observed.

Example 2 Inhibitory Effect of Dihydroartemic Acid on Neutral Fatty Triglycerides

As in Example 1, the immature fat cells 3T3-L1 were treated with MDI to induce differentiation into adipocytes. Then, 10, 25, 50 μM dihydroatomic acid was treated and cultured for 72 hours. The resulting triglyceride was then measured using a triglyceride determination kit (Sigma, USA). The results are shown in Fig.

As a result of the experiment, it was observed that the production of triglyceride, which is a triglyceride, was inhibited as the concentration of dihydroartemic acid increased.

Example 3: Obesity prevention and inhibitory effect by oral administration
