최근 경제발전에 따른 생활수준의 향상으로 인하여 위생환경이 개선되고 식생활의 향상으로 섭취열량 또한 급속한 증가가 이루어지고 있다. 그러나, 음식으로 섭취열량이 증가하는 반면 운동부족 등으로 소비되는 열량이 적어 비만이 증가하는 경향을 보이고 있다. 비만은 젊은이들에게 있어서 마른 체형을 좋아하는 미용적인 모습을 해칠 뿐만 아니라 비만이 지속됨으로써 여러 가지 질환, 즉 고혈압, 당뇨, 고지혈증, 관상동맥질환 등과 같은 성인병을 비롯하여 유방암, 자궁암 및 대장암 등을 야기하는 것으로 보고 되면서 이제는 치명적인 질병으로 취급되고 있다 [J. Biol. Chem., 273, 32487 - 32490 (1998); Nature, 404, 652 - 660 (2000)].Recently, due to the improvement of living standards according to economic development, the hygiene environment is improved and the intake of calories is rapidly increased due to the improvement of diet. However, while calorie intake increases with food, the amount of calories consumed due to lack of exercise, etc. tends to increase obesity. Obesity not only harms young people's skin-like beauty, but also causes obesity to persist, leading to a number of diseases such as hypertension, diabetes, hyperlipidemia, coronary artery disease, as well as breast cancer, uterine cancer and colon cancer. It is reported that the disease is now a fatal disease [J. Biol. Chem., 273, 32487-32490 (1998); Nature, 404, 652-660 (2000)].

현재 비만을 치료하는 치료제로는 크게 중추 신경계에 작용하여 식욕에 영향을 주는 약물과 위장관에 작용하여 흡수를 저해하는 약물로 나누어 볼 수 있다. 중추 신경계에 작용하는 약물로는 각각의 기전에 따라 세로토닌 (5HT) 신경계를 저해하는 펜플루라민, 덱스펜플루라민 등의 약물, 노르아드레날린 신경계를 통한 에페드린 및 카페인 등의 약물 및 최근에는 세로토닌 및 노르아드레날린 신경계에 동시 작용하여 비만을 저해하는 시부트라민 등의 약물들이 시판되고 있다. 이외에도, 위장관에 작용하여 비만을 저해하는 약물로 장관 리파제를 저해하여 지방의 흡수를 줄여줌으로써 비만 치료제로 허가된 오를리스타트 등이 대표적인 약물로 사용되고 있다. 그러나, 기존에 사용되어온 약물 중 펜플루라민 등의 약물은 부작용으로 원발성 폐고혈압이나 심장 판막병변을 일으켜 최근에 사용이 금지되었으며, 다른 약 물들도 혈압감소나 유산산혈증 등의 문제점이 발생하여 심부전, 신질환 등의 환자에는 사용하지 못하는 문제점이 있다.Current treatments to treat obesity can be divided into drugs that act on the central nervous system and affect appetite and drugs that act on the gastrointestinal tract and inhibit absorption. Drugs that act on the central nervous system include drugs such as fenfluramine and dexfenfluramine that inhibit the serotonin (5HT) nervous system according to their respective mechanisms, drugs such as ephedrine and caffeine through the noradrenaline nervous system, and recently serotonin and noradrenaline nervous system. Drugs such as sibutramine that act and inhibit obesity are commercially available. In addition, orlistat, which is approved as an obesity drug by inhibiting intestinal lipase and reducing fat absorption by acting on the gastrointestinal tract and inhibiting obesity, is used as a representative drug. However, among the previously used drugs, drugs such as fenfluramine have been banned recently because of side effects such as primary pulmonary hypertension or heart valve lesions. Other drugs also cause problems such as blood pressure reduction or lactic acidosis, resulting in heart failure and kidney disease. There is a problem that can not be used in the patient.

한편, 비만이 진행되어 당뇨로 진행되는 제 2 형 당뇨병의 경우에 있어서 중성지방인 팔미테이트들이 점진적으로 췌장의 β세포를 파괴하여 당뇨로 진행된다는 결과들이 알려지고 있으며 [Proc. Natl. Acad. Sci. 95, 2498 - 2502 (1998)], 지방간의 진행에도 중성지방의 축적이 관여되고 있음이 보고되고 있다 [J. Clin. Invest., 98, 1575 - 1584 (1996)]. 현재, 제 2형 당뇨병 치료제로 많이 사용하는 약물로는 인슐린 생성이 부족하거나 인슐린이 충분하다 해도 활성이 낮아 체내에서 당을 제대로 활용하지 못하는 인슐린 내성 (insulin resistance)을 치료하기 위하여 혈당 강하제를 사용한다. 이러한 혈당 강하제는 치료기전 및 작용 약물의 작용점에 따라 나누어지는데, 설포닐우레아 계통은 주로 췌장의 베타 세포 안에 있는 인슐린을 함유한 과립포의 이동을 촉진하여 간접적으로 인슐린을 분비시키는 약물로, 저혈당 유발 등의 심각한 부작용이 보고 되고 있으나 최근에는 부작용을 최소화한 약물이 개발되어지고 있다. 또한, 비구아나이드 계통 약물은 근육세포로 당을 이동시키고 간에서 당이 만들어지지 못하게 하는 약물로, 비만한 당뇨 환자에게 사용하며 저혈당을 일으키지 않는 장점을 갖고 있으나 고령자와 심 혈관 질환 환자에게는 주의해야 한다. 또한, 알파-글루코시다아제 저해제는 소장에서 포도당을 만드는 효소 활동을 억제시켜 식후에 일시적으로 혈당이 급상승하는 것을 막아주고, 부작용이 심하지 않은 편이어서 경증 당뇨병 치료에 이용된다. 최근에는, 지방세포의 분화에 관계되는 피피에알 감마를 활성화하는 피페리디온계 약물도 개발되고 있다. 그러나, 경구용 혈당 강하제만으로는 혈당이 효과적으로 떨어지지 않고 이미 알려진 대부분의 약물에서 부작용이 나타나므로 보다 안전한 당뇨병 치료제 개발이 시급한 실정이다. On the other hand, in the case of type 2 diabetes in which obesity progresses to diabetes, it is known that palmitate, a triglyceride, gradually progresses to diabetes by destroying β cells of the pancreas. [Proc. Natl. Acad. Sci. 95, 2498-2502 (1998), reports that triglyceride accumulation is involved in the progression of fatty liver [J. Clin. Invest., 98, 1575-1584 (1996)]. Currently, drugs commonly used to treat type 2 diabetes use hypoglycemic agents to treat insulin resistance, which is insufficient in insulin production even when insulin production is insufficient or insulin is insufficient. . These hypoglycemic agents are divided according to the treatment mechanism and the action point of the action drug. The sulfonylurea line is a drug that indirectly secretes insulin by promoting the movement of granulocytes containing insulin in the beta cells of the pancreas. Serious side effects have been reported, but recently, drugs with minimal side effects have been developed. In addition, the biguanide-based drug is a drug that transfers sugar to muscle cells and prevents sugar from being produced in the liver. It is used in obese patients and does not cause hypoglycemia. However, care should be taken in elderly and cardiovascular patients. . In addition, alpha-glucosidase inhibitors inhibit glucose activity in the small intestine to prevent blood glucose spikes temporarily after a meal, and side effects are not so severe that they are used for treating mild diabetes. In recent years, piperidione-based drugs for activating PPI-gamma related to the differentiation of adipocytes have also been developed. However, oral hypoglycemic agents alone do not drop blood sugar effectively, and most of the known side effects occur in the drug, so it is urgent to develop a safer diabetes treatment.

최근, 제 2형 당뇨병과 단백질 타이로신 탈인산 효소 1B와의 관련성이 밝혀지면서 이의 저해물질이 당뇨병 치료제로서의 개발 가능성이 대두되고 있다 [Nat. Rev. Drug. Discov, 1, 696 - 709, 2002]. 단백질 타이로신 탈인산 효소 1B 유전자에 결함이 있는 쥐의 경우 인슐린 저항성과 비만을 일으키는 능력이 저해되는 현상을 관찰하였으며 [Nature, 283, 1544 - 1548, 1999], 또한 단백질 타이로신 탈인산 효소 1B 저해물질이 제 2형 당뇨병과 비만증에 선택적으로 효과가 있음이 보고 되었다 [JBC, 275, 10300 - 10307, 2000]. 그러나 지금까지 단백질 타이로신 탈인산 효소 1B 저해제 및 지방산 생합성 저해제로서 천연물 유래의 화합물에 대한 보고는 적은 실정이다. Recently, the association between type 2 diabetes and the protein tyrosine dephosphatase 1B has been revealed, the possibility of the development of its inhibitor as a therapeutic for diabetes has emerged [Nat. Rev. Drug. Discov, 1, 696-709, 2002. In mice with a defective protein tyrosine dephosphatase 1B gene, insulin resistance and obesity-inducing ability were inhibited [Nature, 283, 1544-1548, 1999]. It has been reported to be selectively effective for type 2 diabetes and obesity [JBC, 275, 10300-10307, 2000]. However, there are few reports of compounds derived from natural products as protein tyrosine dephosphorase 1B inhibitors and fatty acid biosynthesis inhibitors.

일반적으로, 새로운 성분의 약제를 개발하기 위한 여러 가지 방법 중 기존 약제의 실험적 변형에 의한 노력보다는 전통 의학에서 사용되고 있는 천연물 약제들로부터 새로운 활성 성분을 발견할 수 있는 가능성이 매우 높으며 오랫동안 사용되어 왔기 때문에 개발된 약물들에 의한 독성 염려가 적은 장점이 있다.In general, there is a high possibility of finding new active ingredients from natural medicines used in traditional medicine rather than the efforts of experimental modifications of existing drugs among the various methods for the development of new ingredients of medicine. There is less concern about toxicity due to the drugs developed.

희첨(Hui-Chum)은 우리나라 제주도 및 남부지방에 서식하는 국화과 (Compositae) 식물로서, 제주진득찰(Siegesbeckia orientalis), 진득찰 (Siegesbeckia glabrescens), 털진득찰(Siegesbeckia pubescens) 등의 전초를 한방에서 고혈압, 중풍, 사지마비, 구안와사증 등에 ‘희첨초’라하여 사용되어 왔다. 이러한 희첨에 관계된 특허 및 문헌보고로는 히스타민 유리 저해 [J Ethnopharmacol., 57, 73 - 79, 1997], 육모제 조성물 [대한민국 특허 등록번호 제 10-165937호], 염증질환 치료조성물 [미국특허 제 US, 5,908,628호], 희첨 분획물의 항당뇨효과 [대한민국특허 등록번호 제 10-454097호] 등이 있으나, 희첨 분획물의 화학구조 및 물리화학적 특성에 관한 보고는 없다.
