당뇨병은 대사질환 중에 하나로 인슐린이 정상적으로 분비 되지 않거나 인슐린이 역할을 제대로 하지 못하여 포도당을 소변으로 배출하게 되는 것으로 고혈압, 비만, 대사증후군 등과 같은 다른 질병 등과 함께 발병하며 혈중에 포도당 함량이 높은 것이 주된 특징이다. 당뇨병은 초기증상이 거의 없어 조기에 발견하기 힘든 것으로 알려져 있으며 1형 당뇨와 2형 당뇨로 구분 된다. 1형 당뇨의 경우 선천적으로 췌장에서 인슐린을 분비하지 않는 질환으로 주로 소아 당뇨병이라고 불린다. 선천적으로 인슐린을 분비 하지 않기 때문에 인슐린 치료법을 요한다. 그에 반해 제2형 당뇨병은 선천적으로 인슐린 자체가 생성되지 않는 제 1형 당뇨병과 달리 후천적으로 비만, 비활동적인 생활 등의 환경적인 요인과 유전적인 요인 두 가지로 인해 세포가 포도당을 제대로 흡수하지 못하는 증상이다 (DeFronzo, R. A. 등, 2015). Diabetes is one of the metabolic diseases, and it is caused by the inability to secrete insulin or to excrete glucose in the urine due to the inability of insulin to function properly. to be. Diabetes is known to be difficult to detect early because there are few initial symptoms, and it is classified into type 1 diabetes and type 2 diabetes. Type 1 diabetes is a disease in which the pancreas does not secrete insulin by nature, and is mainly called childhood diabetes. Because it does not secrete insulin by nature, insulin therapy is required. On the other hand, type 2 diabetes, unlike type 1 diabetes, in which insulin itself is not produced by nature, is due to both environmental and genetic factors, such as obesity and inactive life, which prevents cells from absorbing glucose properly. It is a symptom (DeFronzo, RA et al., 2015).
제2형 당뇨병(T2DM)은 세계적으로 중대한 건강관리 문제가 되었고, 보고된 발병률은 놀라운 속도로 증가하고 있다. 치료와 신약 개발의 개선에도 불구하고, 특히 대부분의 이용 가능한 약물의 관련 부작용 때문에 치료는 여전히 불충분하다. 제 2형 당뇨는 서구화된 식습관과 생활의 편리화로 인한 활동량 감소로 인한 비만 인구의 급격한 증가와 밀접한 관련이 있고 이에 따른 전 세계적인 보건 문제가 있다. 우리나라 뿐만 아니라 전 세계적으로 비만인구 증가와 함께 현재 당뇨로 인한 사망자 수 자체도 점차 늘어가고 있는 추세이며 한국 통계청에서 발표한 UN에서 조사한 자료에 따르면 우리나라는 2010년 11,575명, 2015년 11,642명, 2016년 11,986명으로 해마다 당뇨로 인한 사망자 수가 증가하고 있으며 그 외에 UN에서 조사한 134개국 중 극히 일부의 국가들만을 제외하고 해마다 당뇨로 인한 사망자 수는 증가하는 추세이다. 제 2형 당뇨는 여러 가지 기작으로 인해 발병한다. 췌장의 베타 세포 (β-Cell)의 감소, 또는 기능 저하로 인한 인슐린 생성 감소, 간 또는 지방조직에서의 지속적인 염증 반응으로 인한 인슐린 저항성(Insulin-Resistance)과 과도한 지방산 대사로 인한 당 대사 장애, 마지막으로 근육조직에서의 인슐린 저항성(Insulin-Resistance)과 인슐린 부족으로 인해 포도당 흡수가 제한되면서 발병한다. 이러한 발병 기작 중에 췌장의 베타세포를 비롯한 췌장의 문제가 아닌 간, 지방 조직, 그리고 근육 조직에서 나타나는 인슐린 저항성 (Insulin-Resistance)을 세포가 띄게 되면 세포가 인슐린에 의해 포도당 (Glucose) 을 세포가 흡수하여야 하는데 그러지 못 하게 되어 혈중에 포도당 (Glucose)가 과도하게 많아지고 이로 인해 다른 합병증 또한 유발하게 된다. 제 2형 당뇨를 치료하는데 알려진 항당뇨 효과가 있는 기존 약물로는 기본적으로 인슐린 (Insulin)을 비롯하여 메트포르민 (Metformin), 로베글리타존 (Lobeglitazone), 엑세나타이드 (Exenatide), 로지글리타존 (Rosiglitazone) 등이 있다. 이러한 항당뇨 약물은 인슐린 분비 또는 감수성 개선, 포도당 생성 및 흡수 또는 배출 등을 통해 혈당감소를 유도하지만, 이러한 효과와 함께 심각한 부작용과 같은 안정성의 문제가 지속적으로 지적되고 있다. 이로 인하여 현재까지 다양한 항당뇨 약물들이 생산되어져 왔지만 심각한 부작용들로 인해 시판이 중지 된 사례로 로지글리타존 (Rosiglitazone)은 2007년 심근경색 위험과 심혈 관계 사망위험을 증가했다는 내용의 연구논문이 발표되면서 결국 2015년 말 시판이 중단되기도 하였다 (Nissen 등 2007). 현재 미국 식품의약국에서 승인되어 장기간 사용이 가능한 항당뇨제는 간에서의 포도당 생성을 억제시키고 말초 인슐린 감수성을 개선시키는 Metformin ( Dunn CJ, Peters 등, 1995)과 인슐린 민감제 (insulin sensitizer)로 작용하여 인슐린의 표적장기인 간, 근육 간 및 지방세포에서 인슐린 작용을 증가시키는 Lobeglitazone 이 외에도 여러 종들이 있다 (Lee JH, Noh CK 등, 2015). 그러나 이 약물들 또한 비만, 저혈당, 발진, 간 장애, 위장 장애, 백혈구 수치 감소, 빈혈, 젖산산증, 콩팥기능 장애, 인슐린 감소, 탈수 등의 부작용들이 보고되었다. Type 2 diabetes (T2DM) has become a major health care problem worldwide, and reported incidence rates are increasing at an alarming rate. Despite improvements in treatment and drug development, treatment is still insufficient, especially because of the associated side effects of most available drugs. Type 2 diabetes is closely related to the rapid increase of the obese population due to a decrease in activity due to westernized eating habits and convenience of living, and thus there is a global health problem. The number of deaths from diabetes is gradually increasing along with the increase in the obese population not only in Korea but also worldwide.According to data from the United Nations released by the National Statistical Office of Korea, Korea had 11,575 people in 2010, 11,642 people in 2015, and 2016. The number of deaths from diabetes is increasing every year to 11,986, and the number of deaths from diabetes is increasing every year except for only a few of the 134 countries surveyed by the United Nations. Type 2 diabetes develops due to several mechanisms. Decreased pancreatic beta cells (β-Cell), or decreased insulin production due to decreased function, insulin-resistance due to persistent inflammatory response in liver or adipose tissue and impaired glucose metabolism due to excessive fatty acid metabolism, last Insulin-Resistance and lack of insulin in the muscle tissue causes the absorption of glucose to be limited. During this pathogenesis, if the cells become insulin-resistance that appears in liver, adipose tissue, and muscle tissue, not pancreatic problems including pancreatic beta cells, cells absorb glucose by insulin. It should be done, but not being able to do so, resulting in excessive increase in glucose in the blood, which causes other complications. Existing drugs that have antidiabetic effects known to treat type 2 diabetes are basically insulin, metformin, lobeglitazone, exenatide, rosiglitazone, etc. There is this. These antidiabetic drugs induce a decrease in blood sugar through insulin secretion or sensitivity improvement, glucose production and absorption or excretion, but stability problems such as serious side effects along with these effects have been continuously pointed out. As a result, various antidiabetic drugs have been produced so far, but the market was stopped due to serious side effects.Rosiglitazone increased the risk of myocardial infarction and cardiovascular death in 2007. The market was discontinued at the end of the year (Nissen et al. 2007). Antidiabetic drugs that are currently approved by the U.S. Food and Drug Administration and can be used for a long period of time act as metformin (Dunn CJ, Peters et al., 1995) and insulin sensitizer, which inhibits the production of glucose in the liver and improves peripheral insulin sensitivity. In addition to Lobeglitazone, which increases insulin action in liver, muscle liver and adipocytes, which are target organs of insulin, there are several other species (Lee JH, Noh CK et al., 2015). However, these drugs also have side effects such as obesity, hypoglycemia, rash, liver disorder, gastrointestinal disorder, decreased leukocyte count, anemia, lactic acidosis, kidney dysfunction, decreased insulin, and dehydration.

Recently, research on antidiabetic drugs using medicinal plants is active. Among them, Registration Patent 10-2019-0102834 describes a method for preparing a food having anti-obesity and anti-diabetic activity including the deodeok extract. For this reason, attention has been focused on research to develop various antidiabetic drugs that treat or prevent diabetes. Due to the various side effects of diabetes treatment drugs, studies have recently been conducted to develop diabetes treatment drugs using natural products such as compounds isolated from plants, microorganism-derived natural substances, and flavonoids with minimal side effects to the human body. Among natural substances with various antidiabetic effects, the efficacy of the flavonoid series Quercetin, the largest group among plant-derived polyphenols that can be easily encountered in the surroundings, is already known through many papers (Chen S et al., 2016). . However, the antidiabetic efficacy of the quercetin-3-O-xyloside purified substance has not been reported worldwide.

Then, mix 10 μL of buffer solution, 20 μL of Quercetin-3-O-xyloside or acarbose sample and 20 μL of α-Glucosidase enzyme solution in a 96-well plate, and mix 5% CO2, 37°C incubator ( incubator) for 15 minutes. In addition, since pNPG and α-Glucosidase enzyme solution reacted, a difference in absorbance may occur, so the control group was set to increase the accuracy. In addition, since the absorbance may vary due to the color development of the sample itself, a blank group was set. Thereafter, 20 μL of pNPG solution was mixed with each sample, added to Control and Blank, and incubated again for 15 minutes in 5% CO2, 37°C incubator. This reaction was terminated by adding 130 μL of 0.2 M sodium carbonate solution. In the blank, the α-Glucosidase enzyme solution was replaced with a buffer solution. In Control, the sample was replaced with a buffer solution. Then, the absorbance was measured at 405 nm with an ELISA reader. The measurement results are shown in Fig. 2. As a result of the measurement, in the case of IC 50, acarbose currently used as a drug on the market was 1.155 mM, whereas the result of Quercetin-3-O-xyloside was about 0.414 mM, and α-Glucosidase inhibitory activity. As a result, it was confirmed that quercetin-3-O-xyloside has better alpha-glucosidase inhibitory properties than acarbose.
