Description

아실 코에이:디아실글리세롤 아실트랜스퍼라제활성 저해제인 신규 폴리아세틸렌계 화합물 및 이의 제조방법{Polyacetylene group compounds, novel inhibitors of acyl CoA:diacylglycerol acyltransferase and the process for preparing thereof}Polyacetylene group compounds, novel inhibitors of acyl CoA: diacylglycerol acyltransferase and the process for preparing according to the acyl coay: diacylglycerol acyl transferase inhibitor

본 발명은 아실 코에이:디아실글리세롤 아실트랜스퍼라제 활성 저해제인 신규 폴리아세틸렌계 화합물 및 이의 제조방법에 관한 것으로서, 더욱 상세하게는 아실 코에이:디아실글리세롤 아실트랜스퍼라제(Acyl CoA:diacylglycerol acyltransferase) 활성을 저해하여 중성지방이 체내에 흡수되는 것과 간, 지방 세포, 근육 세포 등에서의 중성지방의 생합성을 저해하여 중성지방의 장기 내 축적을 억제함으로써 체중을 감소시켜 비만 치료에 효과적인 아실 코에이:디아실글리세롤 아실트랜스퍼라제 활성 저해제인 신규 폴리아세틸렌계 화합물과 이의 제조방법에 관한 것이다.The present invention relates to a novel polyacetylene-based compound which is an acyl coa: diacylglycerol acyltransferase activity inhibitor and a method for preparing the same, and more particularly, to an acyl coa: diacylglycerol acyltransferase. Acyl coay is effective in treating obesity by inhibiting activity and inhibiting the absorption of triglycerides into the body and inhibiting the biosynthesis of triglycerides in liver, fat cells, muscle cells, etc. The present invention relates to a novel polyacetylene-based compound which is a silglycerol acyl transferase inhibitor, and a preparation method thereof.

아실 코에이:디아실글리세롤 아실트랜스퍼라제(Acyl CoA:diacylglycerol acyltransferase, 이하 DGAT라 칭함)는 글리세롤 3-포스페이트 경로의 마지막 과정을 촉매하는 효소로서 1,2-디아실글리세롤(sn-1,2-diacylglycerol)과 페티 아실 코에이를 기질로 사용하여 트리글리세라이드를 생성한다. 외부로부터 섭취된 중성지방은 췌장에서 분비된 리파제에 의해 지방산과 모노글리세라이드로 분해되어 장 상피세포를 통해 흡수된 후, DGAT에 의해 트리글리세라이드 중성지방으로 된다.Acyl co A: diacylglycerol acyltransferase (Acyl CoA: diacylglycerol acyltransferase la, hereinafter referred to as DGAT) include 1,2-diacyl glycerol as the enzyme catalyzing the last step of the glycerol 3-phosphate pathway (sn -1,2- triglycerides are produced using diacylglycerol) and pettyacylcoei as substrates. Triglycerides ingested from the outside are broken down into fatty acids and monoglycerides by lipase secreted from the pancreas, absorbed through intestinal epithelial cells, and then triglyceride triglycerides by DGAT.

중성지방의 생합성은 글리세롤 3-포스페이트 경로(간과 지방조직)와 모노아실글리세롤 경로에 의해 소장의 장 상피세포에서 주로 이루어지며, 이들 생합성 과정에 작용하는 효소인 DGAT의 선택적 저해에 의한 중성지방 합성저해는 비만, 고 중성지방혈증 등과 같은 중성지방 대사이상에 의한 질병의 예방 및 치료에 효과적인 작용점으로 부상되고 있다.Biosynthesis of triglycerides is mainly performed in the intestinal epithelial cells of the small intestine by the glycerol 3-phosphate pathway (liver and adipose tissue) and monoacylglycerol pathway, and neutral lipid synthesis is inhibited by selective inhibition of DGAT, an enzyme that acts on these biosynthetic processes. Has emerged as an effective point of action for the prevention and treatment of diseases caused by triglyceride metabolism, such as obesity, hypertriglyceridemia.

간의 소포체에서 합성된 중성지방은 콜레스테롤, 인지질, 단백질(apo-100)과 결합하여 초저비중 리포단백질(VLDL)로 되어 혈액 내로 분비된다. 혈액 내로 들어온 키로마이크론과 VLDL은 혈관의 내피세포에 존재하는 리포단백질 리파아제에 의해 글리세롤과 지방산으로 분해되며 이때 생성된 지방산은 지방세포로 이동하여 페티 아실코에이로 활성화된 후 글리세롤 3-포스페이트 경로를 거쳐 중성지방으로 합성되어 저장된다.Triglycerides synthesized in the endoplasmic reticulum are combined with cholesterol, phospholipids and proteins (apo-100) to form very low specific lipoprotein (VLDL) and secreted into the blood. Chiromicrons and VLDL enter the blood and are broken down into glycerol and fatty acids by lipoprotein lipases present in endothelial cells of blood vessels. It is then synthesized and stored as triglycerides.

중성지방의 생합성과 에너지 저장 기능은 장관의 지방 흡수, 리포단백질 조립, 혈장 중성지방의 조절, 지방세포 내 지방 축적, 근육에서의 에너지 대사, 유즙 분비 등에 연관되어 중요한 생리적 기능을 담당하고 있다.Triglyceride biosynthesis and energy storage are important physiological functions associated with intestinal fat absorption, lipoprotein assembly, regulation of plasma triglycerides, fat accumulation in adipocytes, energy metabolism in muscles, and milk secretion.

그러나, 중성지방이 장기나 조직에 과도하게 축적이 일어나면 지방간, 비만, 고 중성지방혈증 등을 야기시켜 동맥경화, 당뇨, 대사이상 및 장기의 기능 저하 등의 심각한 질병을 유발한다. 당뇨병환자의 약 1/3에서 혈장 중성지방 농도가 증가되어 있다. 이는 혈당조절이 안된 당뇨병환자에서 두드러지지만 비교적 조절이 잘된 인슐린 비의존형(제 2형) 당뇨병에서도 인슐린 저항성이 심하면 고 중성지방혈증이 발생하는 경우가 있다. 비만증은 제 2형 당뇨병을 수반하며 비만증의 원인들이 매우 다양하기에 제 2형 당뇨병의 발병에 관여하는 기전도 매우 복잡하다. 비만증에서 관찰되는 가장 중요한 대사장애로 고 인슐린혈증과 인슐린저항성이 동반되는 현상이 있다. 이때 혈청 중성지방과 유리 지방산의 증가 및 고혈압도 잘 동반된다.However, excessive accumulation of triglycerides in organs or tissues causes fatty liver disease, obesity, hypertriglyceridemia and the like, and causes serious diseases such as arteriosclerosis, diabetes, metabolic abnormalities and deterioration of organ function. Plasma triglyceride levels are elevated in about one third of diabetics. This is noticeable in diabetic patients with poor glycemic control, but hypertriglyceridemia occurs when insulin resistance is severe even in relatively insulated insulin-dependent (type 2) diabetes. Obesity involves type 2 diabetes and the causes of obesity are so diverse that the mechanisms involved in the development of type 2 diabetes are very complex. The most important metabolic disorders observed in obesity include hyperinsulinemia and insulin resistance. The increase in serum triglycerides and free fatty acids and hypertension is also well accompanied.

이 DGAT는 생체의 지방세포, 분화된 3T3-L1 지방세포, 소장내의 장 상피세포, 유선, 골격근, 심근 등 여러 조직에서 발견되고 있으며, 식물, 미코박테리움속과 스트렙토미세스속 같은 미생물, 곰팡이나 곤충에서도 발견되고 있다.This DGAT is found in many tissues such as fat cells, differentiated 3T3-L1 adipocytes, intestinal epithelial cells in the small intestine, mammary gland, skeletal muscle, and myocardium.It is a plant, microorganism such as Mycobacterium and Streptomyces, fungi It is also found in insects.

DGAT는 지방세포 분화 시 효소활성이 증가하여 NIH3T3-L1 섬유아세포가 지방세포로 분화되는 동안 DGAT 유전자 발현과 효소활성이 현저히 증가됨을 알 수 있다. 이 효소는 중성지방 합성과 흡수에 관여하며 그 활성은 생체 대사조절 상태에 따라 조절된다. 예를 들어, 세포 내 유리 지방산의 농도가 증가하면 에너지 저장이 쉽게 도와주며 과도한 지방산에 의한 독성을 방어하기 위해 DGAT의 활성은 증가하게 된다. 세포 내 유리 지방산이 부족하면 인지질 합성을 위한 유리 지방산의 이용성을 유지하기 위해 활성이 감소된다. 또한, 이 효소는 인슐린과 아드레날린 등의 호르몬과 티로신키나제 등에 의해서도 조절을 받는 것으로 알려졌다.In DGAT, the enzyme activity was increased during adipocyte differentiation, and the expression of DGAT gene and enzyme activity were significantly increased during NIH3T3-L1 fibroblast differentiation into adipocytes. The enzyme is involved in triglyceride synthesis and absorption, and its activity is regulated by biomechanical control. For example, increasing the concentration of free fatty acids in cells facilitates energy storage and increases the activity of DGAT to defend against toxicity by excess fatty acids. Lack of free fatty acids in cells reduces activity to maintain the availability of free fatty acids for phospholipid synthesis. The enzyme is also known to be regulated by hormones such as insulin and adrenaline, tyrosine kinases and the like.

DGAT 효소는 1960년 닭의 간에서 처음으로 확인되었으며 막에 걸쳐있는 효소로 분리정제의 어려움으로 연구의 진전을 보지 못하다가, 1998년 포유류 유래 DGAT cDNA가 클로닝됨으로써 중성지방 생합성의 분자생물학적 연구의 기원을 이루게 되었다[Cases et al. Proc. Natl. Acad. Sci. USA 95, 13018-13023, 1998].The DGAT enzyme was first identified in the liver of chickens in 1960, and it is a membrane-enzyme that has not progressed due to the difficulty of purification and purification. [Cases et al. Proc. Natl. Acad. Sci. USA 95, 13018-13023, 1998].

최근 동정된 DGAT 유전자의 생체 내 기능을 밝히기 위해 Smith 등에 의해 만들어진 DGAT-결핍 쥐로부터 DGAT에 의한 선택적인 중성지방의 합성저해가 비만의 치료에 유용하다는 사실을 시사하는 보고가 있었다[Smith et al. Nature Genetics 25, 87-90, 2000].Recently, there have been reports suggesting that the inhibition of DGAT-selective triglyceride synthesis from DGAT-deficient mice made by Smith et al. To shed light on the in vivo function of the DGAT gene identified [Smith et al. Nature Genetics 25, 87-90, 2000].

DGAT-결핍 쥐는 정상적인 생존과 번식능을 보여주고 있었다. 정상 식이 동안 여전히 중성지방을 합성하고 정상적인 체지방을 유지하고 있는 결과로부터 중성지방은 DGAT의 경로와는 다른 경로에 의해 합성됨을 보여주었다. 흥미롭게도 이들은 고지방 식이에 대하여 정상 쥐는 40 ∼ 50%의 체중 증가를 보인 반면, DGAT-결핍 쥐는 정상 식이 때의 체중증가와 유사한 양상을 보임으로써 고지방 식에 대한 저항성을 보여주었다. 이는 대사율의 증가와 운동량의 증가에 따른 에너지 소비의 증가로 나타났으며 식이 섭취의 감소와는 무관한 것으로 밝혀졌다. 또한, 포도당, 인슐린, 유리 지방산의 혈장 내 농도는 정상 쥐과 유사했으나 DGAT-결핍 쥐의 경우, 인슐린의 감도가 증가하여 더 낮은 포도당과 인슐린의 농도를 나타내는 경향을 보였다.DGAT-deficient mice showed normal survival and reproduction. The results show that triglycerides are synthesized by a route different from that of DGAT, while still maintaining triglycerides and maintaining normal body fat during normal diet. Interestingly, they showed a 40-50% weight gain for high fat diets, while DGAT-deficient mice showed a similar pattern of weight gain for normal diets, indicating resistance to high fat diets. This resulted in an increase in energy consumption with increasing metabolic rate and exercise, and was found to be independent of the decrease in dietary intake. Plasma concentrations of glucose, insulin and free fatty acids were similar to those of normal rats, but DGAT-deficient mice showed increased sensitivity to insulin, indicating lower glucose and insulin concentrations.

현재 DGAT 효소저해제의 합성은 미진한 상태이며 천연물로부터 몇 종의 저해제가 보고되어 있는 실정이다. 대부분이 일본의 기타사토 연구소의 Omura 그룹에서 보고한 저해제로 로셀리핀스(roselipins)[Gliocladium roseumKF-1040, IC50; 15∼22 μM], 아미데프신스(amidepsines)[Humicolasp. FO-2942, IC50; 10∼50 μM], 크산토후몰스(xanthohumols)[Humulus lupulus, IC50; 50∼194 μM], 그외 에이코사펜타에노익산(eicosapentaenoic acid), 2-브로모옥타노에이트(2-bromooctanoate)가 보고되어 있을 뿐이다[Tomoda et al. J. Antibiotics 52, 689-694, 1999, Tomoda et al. J. Antibiotics 48,937-941, 1995, Tabata et al. Phytochemistry 46, 683-687, 1997, Rustan et al. J. Lipid. Res. 29, 1417-1426, 1988].Currently, the synthesis of DGAT inhibitors is incomplete and several inhibitors have been reported from natural products. Most of the inhibitors reported by the Omura group of the Kitasato research institute in Japan were roselipins [ Gliocladium roseum KF-1040, IC 50 ; 15-22 μM], amiddefines (amidepsines) [ Humicola sp. FO-2942, IC 50 ; 10-50 μM], xanthohumols [ Humulus lupulus , IC 50 ; 50-194 μM], other eicosapentaenoic acid and 2-bromooctanoate have been reported [Tomoda et al. J. Antibiotics 52, 689-694, 1999, Tomoda et al. J. Antibiotics 48,937-941, 1995, Tabata et al. Phytochemistry 46, 683-687, 1997, Rustan et al. J. Lipid. Res. 29, 1417-1426, 1988.

이상의 결과로부터 DGAT 저해활성을 갖는 약물은 비만치료에 사용할 수 있다. 외부로부터 섭취된 중성지방은 췌장에서 분비된 리파제에 의해 지방산과 모노 글리세라이드로 분해되어 장 상피세포를 통해 흡수된 후, DGAT에 의해 중성지방으로 재합성되는데 DGAT의 활성을 억제하는 약물은 중성지방을 재합성하는 단계를 저해하여 지방의 흡수를 억제함으로써 체내로 유입되는 중성지방의 양을 감소시킬 수 있다. 또한, DGAT 저해제는 간, 지방세포, 근육세포 등에서의 중성지방의 생합성과 저장형 중성지방의 축적을 방지하고 이미 축적된 지방의 소비를 촉진시킴으로써 비만치료가 가능할 것으로 기대된다.From the above results, drugs with DGAT inhibitory activity can be used for the treatment of obesity. Triglycerides taken from the outside are broken down into fatty acids and monoglycerides by lipase secreted by the pancreas, absorbed through intestinal epithelial cells, and then resynthesized into triglycerides by DGAT. Drugs that inhibit DGAT activity are triglycerides. By inhibiting the step of resynthesis can inhibit the absorption of fat can reduce the amount of triglycerides introduced into the body. In addition, DGAT inhibitors are expected to be able to treat obesity by preventing the biosynthesis of triglycerides and accumulation of storage-type triglycerides in liver, adipocytes, muscle cells and the like, and by promoting the consumption of the already accumulated fat.

이에, 본 발명자들은 한국의 자생식물로부터 DGAT를 억제하는 활성물질을 탐색하는 과정에서 인삼을 탐색하였으며 이로부터 신규 폴리아세틸렌계 화합물을 발견할 수 있었다.Therefore, the present inventors searched for ginseng in the process of searching for an active substance that inhibits DGAT from Korean native plants, and found a new polyacetylene compound.
