참당귀로부터 데쿨시놀을 고수율로 제조하는 방법{A method for preparing decursinol from Angelica gigas with high yield}A method for preparing decursinol from Angelica gigas with high yield}

본 발명은 참당귀로부터 데쿨신 유도체 합성의 전구체가 되는 데쿨시놀을 고수율로 제조하는 방법에 관한 것이다. The present invention relates to a method for producing deculinol, which is a precursor of deucine derivative synthesis, from a real donkey, in high yield.

근래에 데쿨신(decursin)을 유효성분으로 포함하는 항암제의 개발이 활발히 이루어지고 있다. 데쿨신은 당귀에서 추출되는 성분으로 1966년 일본에서 최초로 바디나물(Angelica decursiva Fr. et Sav.)에서 분리된 천연물질이며 데쿨신이 한국산 참당귀(Angelica gigas Nakai)에 다량 함유되어 있다는 것은 1967년과 1969년(J., Pharm . Soc. Korea, 11, pp.22∼26, 1967 및 13, pp.47∼50, 1969) 밝혀졌으며, 그 밖의 식물로는 기름나물(Peucedanum terevinthaceum Fisher et Turcz.)의 과실에서도 분리된 바 있다(한국약학회지, 30(2), pp.73∼78, 1986).Recently, the development of anticancer drugs containing decursin as an active ingredient is being actively made. Dekulcin is a natural substance extracted from Angelica decursiv a Fr. et Sav., Which was first extracted from Angelica in 1966, and it was found that dekulcin was contained in Korean Angelica gigas Nakai in 1967. In 1969 (J., Pharm . Soc. Korea , 11 , pp.22-26, 1967 and 13 , pp.47-50, 1969), and other plants are oil sprouts (Peucedanum terevinthaceum Fisher et Turcz.) It was also isolated from the fruit of Korean Pharmacy (30 (2) , pp.73 ~ 78, 1986).

데쿨신은 암세포에 대해서는 강한 치사작용을 나타내는 반면, 정상세포에 대해서는 암세포에 대한 치사작용에 비해 훨씬 낮은 치사작용을 나타내어 항암제로서의 사용 가능성을 가지고 있다. 기존의 데쿨신은 바디나물의 에테르 추출액으로부 터 최초로 분리된 후, 한국산 당귀 및 기름나물의 과실에서도 분리되었다고 보고되었으나, 항암제로서 데쿨신을 사용하려면 대량의 데쿨신이 요구되며 데쿨신의 활성을 증가시키기 위한 유도체의 개발에 있어서도 데쿨신의 전구체인 데쿨시놀의 합성은 중요한 의미를 갖는다.Decucine has a strong lethal action on cancer cells, while it has a far lower lethal action on cancer cells than on cancer cells, and thus has potential for use as an anticancer agent. Conventional deucine has been reported to have been separated from the fruit extracts of the body herb first, and also from the fruit of Korean Angelica and oil herb. However, the use of deculin as an anticancer agent requires a large amount of deucine and a derivative to increase the activity of deculin. Also in the development of the synthesis of dekulsinol, a precursor of dekulsin has an important meaning.

데쿨시놀류의 백혈병 치료제 및 신장독성 경감제로서의 효능이 산업화될 경우 백혈병의 치료효과는 암환자들에게 새로운 희망을 가져다줄 것으로 생각되며, 신부전증에 걸린 많은 환자들이 평생 동안 신장 투석으로 고생하는 것과 투석에 드는 많은 사회적, 개인적인 비용을 고려할 때에 데쿨신의 신장보호 효과는 당뇨병환자들의 건강 증진, 중금속오염 및 약물남용에 의한 신장손상 예방을 통하여 복지사회 구현에 크게 이바지할 수 있을 것이다. When deucusinol is used as a treatment for leukemia and as a renal toxicant, the therapeutic effect of leukemia will bring new hope to cancer patients. Many patients with renal failure suffer from renal dialysis and have dialysis. Considering the many social and personal costs of ED, decousin's renal protective effect can greatly contribute to the welfare society by improving the health of diabetics and preventing kidney damage caused by heavy metal contamination and drug abuse.

참당귀(Angelica gigas)는 쌍떡잎식물 이판화군 산형화목 미나리과의 숙근초로 산골짜기 냇가 근처에 서식하고 있다. 어린순을 나물로 식용하고 뿌리를 당귀라고 하며 약제로 사용한다. 당귀는 중국산을 중국당귀(A. sinesis), 일본산을 왜당귀(A. acutilobae), 한국산을 참당귀라고 한다.Angelica Angelica gigas ) is a distilled herb of the dicotyledon-plant type Aphrodisiac apiaceae, and lives near the valley stream. Young sprouts are eaten as herbs, and the root is called Angelica. Angelica is called the Chinese Chinese angelica (A. sinesis), why the Japanese angelica (A. acutilobae), the Korean Angelica gigas.

참당귀는 한국이 원산지로서 그 사용 범위가 보혈제로서 한방약제로 이용되어져 왔으며 최근에는 한국산 지표물질인 데쿨신과 주요 성분인 데쿨시놀이 혈류개선 작용과 항 헬리코박터 작용이 있다고 보고되어 있으며 순수 정제된 데쿨신이 신장독성 억제와 당뇨합병증에 의한 신부전증의 예방 효과 및 당뇨성 고혈압에 효과가 있음을 동물실험을 통하여 밝혀진바 있다(PCT/KR99/00632). Champagne Angelica has been used as an herbal medicine as a blood donor in Korea as a country of origin, and recently, it has been reported that dekulsin, a Korean indicator, and dekulsinol, its main components, have blood flow improvement and anti-helicobacter action, and pure purified decousin is a kidney. Animal testing has been shown to be effective in inhibiting toxicity, preventing the renal failure caused by diabetic complications and diabetic hypertension (PCT / KR99 / 00632).

또한 기존에 알려진 데쿨시놀 제조방법은 합성에 의한 방법과 참당귀를 용매 추출한 후 실리카겔 컬럼크로마토그래피를 통하여 일차적으로 분획물을 얻은 후 가수분해, 산추출한 후 다시 실리카겔 컬럼크로마토그래피를 통하여 데쿨시놀을 제조하는 방법이기 때문에 물질의 순도 문제, 대량 제조의 문제, 번거롭고 복잡한 공정 및 원료비용의 문제 등이 있었다.In addition, a known method for preparing dekulsinol is a method of synthesizing a solvent and extracting a true donkey, and then obtaining a fraction through silica gel column chromatography, followed by hydrolysis and acid extraction, followed by silica gel column chromatography. As a method of manufacturing, there were problems of purity of materials, problems of mass production, troublesome and complicated processes, and raw material costs.

이에 따라, 본 발명자들은 참당귀로부터 데쿨신 유도체 합성의 전구체가 되는 데쿨시놀을 고수율로 제조하는 개발 필요성을 느끼고 지속적인 연구 개발을 통해 본 발명을 완성하였다. Accordingly, the present inventors have felt the necessity of developing a high yield of defucinol, which is a precursor of deucine derivative synthesis, from the Angelica gigas, and completed the present invention through continuous research and development.

본 발명에서는 데쿨신 유도체 합성의 전구체가 되는 데쿨시놀을 고수율로 제조하는 방법을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a method for producing deculinol, which is a precursor for deucine derivative synthesis, in high yield.

본 발명의 가수분해는 수산화나트륨, 수산화칼륨, 탄산칼륨 중 어떤 염기를 사용해도 좋은 수율로 데쿨시놀을 수득할 수 있었으며, 이들 염기는 가격면에서도 크게 차이가 나지 않았다. 단, 탄산수소나트륨은 수율과 순도가 다소 떨어짐을 확인할 수 있었다. In the hydrolysis of the present invention, it was possible to obtain deculinol in a good yield using any base of sodium hydroxide, potassium hydroxide, potassium carbonate, and these bases did not differ significantly in price. However, the sodium bicarbonate was confirmed that the yield and purity slightly decreased.
