Description
본 발명은 세복수초(Adonis amurensis) 추출물 또는 그 유효물질을 이용한 항암제 조성물에 관한 것이다.The present invention relates to an anticancer drug composition using Adonis amurensis extract or its active substance.
암이란 일반적으로 인체 조직을 이루고 있는 세포의 주기에 이상이 생겨 세포가 정상적으로 분화하지 않고 성장을 조절할 수 없이 커진 것 중 악성인 것을 말한다.Cancer is generally a malignant one of abnormalities in the cycles of the cells that make up human tissues, and cells that do not differentiate normally and grow uncontrollably.
암은 개시(initiation), 촉진(promotion) 및 진행(progression)의 세 단계를 거쳐 발생하는데, 환경이나 음식물 속에 포함된 발암 물질에 의해 세포 돌연변이가 일어나고 이러한 세포들이 발암 물질의 계속적인 자극을 받으면서 비정상적인 증식을 계속하여 암 조직을 형성하는 것으로 알려져 있다.Cancer occurs through three stages: initiation, promotion, and progression. Cellular mutations are caused by carcinogens in the environment or food, and these cells are abnormal as they are continuously stimulated by carcinogens. It is known to continue to proliferate to form cancer tissue.
암을 치료하기 위한 항암제의 연구 방법에는 암세포에 대한 직접적인 세포 독성 물질을 탐색하는 방법, 생체의 면역 능력을 조절하는 물질을 탐색하는 방법, 암세포의 전이를 억제하는 물질을 탐색하는 방법, 최근에 주목되고 있는 혈관신생을 억제하는 물질을 탐색하는 방법 등이 있다.Research methods for anticancer drugs for treating cancer include a method of searching for direct cytotoxic substances on cancer cells, a method of controlling substances that regulate the immune ability of the living body, a method of searching for substances that inhibit the metastasis of cancer cells, and the like. There is a method of searching for a substance that suppresses angiogenesis.
현재 사용되고 있는 항암제들은 효소 제제나 백신 등의 생물학적 제제, 화학 합성 의약품, 천연물 유래의 의약품 등으로 크게 구분할 수 있는데, 이 중 효소, 백신 등의 생물학적 제제는 실용 단계에 있는 상태는 아니며, 화학 합성 의약품은 암의 종류에 따라 약리작용이 다양하고(Gillman., et al., Maxwell Macmillan. 18, pp1202, 1986), 독성에 의한 부작용이 다양하게 나타나기 때문에 암 치료시 문제점으로 지적되고 있다(Chung., et al., J. Wonkwang Medical Sci. , 3 , pp 13-34, 1987).Currently used anticancer drugs can be broadly classified into biological preparations such as enzyme preparations and vaccines, chemical synthesis medicines, and natural products. Among them, biological preparations such as enzymes and vaccines are not in a practical stage. Pharmacological action varies depending on the type of cancer (Gillman., Et al., Maxwell Macmillan. 18, pp1202, 1986), and various side effects due to toxicity have been indicated as problems in cancer treatment (Chung., et al., J. Wonkwang Medical Sci., 3, pp 13-34, 1987).
이러한 화학 합성 항암제의 부작용을 최소화하고 치료 효과를 높이기 위하여 식물 추출물을 이용한 항암제의 개발이 지속적으로 시도되고 있다.In order to minimize the side effects of the chemosynthetic anticancer drugs and increase the therapeutic effect, the development of anticancer drugs using plant extracts has been continuously attempted.

J Neurochem 99(4):1251-1262) 등 여러 종류의 암에 대해 항암 효과가 있음이 보고되어 있으며, 또한 예컨대 감초(Glycyrrhiza glabra)의 뿌리 추출물이 전립선암(Kanazawa M, Satomi Y, Mizutani Y, Ukimura O, Kawauchi A, Sakai T, Baba M, Okuyama T, Nishino H, Miki T. 2003. Eur Urol 43(5) :580-586)이나 유방암(Jo EH, Lim SH, Ra JC, Kim SR, Cho SD, Jung JW, Yang SR, Park JS, Hwang JW, Aruoma OI, Kim TY, Lee YS, Kang Ks. 2005. Cancer Lett. 230(2): 239-247)에 항암 효과가 있음이 알려져 있다. Many plant extracts with anticancer activity have been reported (Pujol M, Gavilondo J, Ayala M, Rodriguez M, Gonzalez EM, Perez L. 2007 Trends Biotechnol 25 (10): 455-459). For example, Angelica gigas extract can be used for colon cancer (KanWL, Cho CH, Rudd JA, Lin G. 2008. 120 (1): 36-43), and colon cancer (Lu J. Kim SH Jiang C, Lee H Guo J. 2007). Acta Pharmacol Sin. 28 (9): 1365-1372), brain cancer (Tasi NM, Chen YL, Lee CC, Lin PC, Cheng YL, Chang WL, LIn SZ, Ham HJ. 2006. J Neurochem 99 (4): 1251-1262) have been reported to have an anticancer effect on several types of cancer, and for example, root extracts of licorice ( Glycyrrhiza glabra ) may be used for prostate cancer (Kanazawa M, Satomi Y, Mizutani Y, Ukimura O, Kawauchi A, Sakai). T, Baba M, Okuyama T, Nishino H, Miki T. 2003.

<실시예 2> <Example 2> 유효물질의 분리 및 동정Isolation and Identification of Active Substances
상기 에틸아세테이트 분획물 8g을 취해 셀라이트545와 혼합한 후 감압농축하여 혼합물을 만든 후 오픈컬럼크로마토그래피를 실시하였다. n-Hex., MC(methylene chloride), DE(Diethyl ether), EA(Ethyl acetate), Methanol(MeOH)을 이동상으로 사용하여 총 5개의 소분획을 얻었다. 그 중 DE(800mg) 분획물에 대해 실리카겔 컬럼크로마토그래피를 실시하였다. Chloroform/MeOH(9/2)을 이동상으로 사용하였으며 분 당 2.5ml 유속으로 흘려주어 총 18개의 소분획을 얻었다. 그 중 14번(DE-14)분획에 대해 간단히 정제를 실시하여 단일화합물(compound 1)을 확보하였다.8 g of the ethyl acetate fractions were mixed with celite 545, concentrated under reduced pressure to form a mixture, and then subjected to open column chromatography. Five small fractions were obtained using n-Hex., MC (methylene chloride), DE (Diethyl ether), EA (Ethyl acetate), and Methanol (MeOH) as mobile phases. Among them, DE (800 mg) fractions were subjected to silica gel column chromatography. Chloroform / MeOH (9/2) was used as the mobile phase and a total of 18 small fractions were obtained by flowing at a flow rate of 2.5 ml per minute. The 14th fraction (DE-14) was briefly purified to obtain a single compound (compound 1).
분리된 물질의 구조를 분석하기 위해 단일화합물 10mg을 메탄올-d에 녹여 NMR spectrum을 측정하였다. 1H NMR 스펙트럼(도 1 및 도 3)에서 3개의 메틸기를 확인했으며 모두 싱글렛으로 3개의 메틸기 모두 4차 탄소와 결합하고 있음을 예상하였고, 4ppm 시그널들로 미루어 1개 이상의 벤젠고리가 있음을 예상하였다. 또한 3.7-3.3ppm 부근의 복잡한 시그널들로 미루어 1개 이상의 당이 결합하고 있음을 예상하였다. 13C NMR(도 2 및 도 3) 및 DEPT NMR(도 4) 스펙트럼에서 총 21개 이상의 탄소가 존재함을 예측하였고 105.8ppm에서 아노머 탄소를 확인하였다. To analyze the structure of the separated material, 10 mg of a single compound was dissolved in methanol-d and the NMR spectrum was measured. Three methyl groups were identified in the 1 H NMR spectra (FIGS. 1 and 3) and all were predicted that all three methyl groups bound to quaternary carbon as singlets, and that at least one benzene ring was expected from 4 ppm signals. It was. It was also expected that more than one sugar would bind due to complex signals around 3.7-3.3 ppm. A total of 21 or more carbons were predicted in 13C NMR (FIGS. 2 and 3) and DEPT NMR (FIG. 4) spectra and anomer carbon was identified at 105.8 ppm.
그리고 H-H COSY 스펙트럼(도 5)에서 벤젠고리의 프로톤(H-11, δ6.40)과 메틸기의 프로톤(H-15, δ2.2)이 커플링하고 있음을 확인하였다. 따라서 H-15 메틸기는 벤젠고리에 결합하고 있으며, HSQC 스펙트럼과 HMBC 스펙트럼(도 7) 분석 결과(도 6) 아노머 수소(H-1', δ105)와 벤젠고리 탄소(C-9, δ146)의 커플링을 확인하였다. 그리고 벤젠고리에 연결된 메틸기는 C-9(δ146), C-10(δ129), C-11(δ116)과 커플링하고 있어 C-10과 결합하고 있음을 예상하였다. 또한 벤젠링의 수소(H-11, δ6.4)가 각각 C-9, C-12, C-7과 커플링하고 있어 C-9, C-7과는 오르토, C-12와 메타, C-8과는 파라 위치에 있음을 확인하였다. 메틸기 수소(H-14, δ1.7)가 벤젠고리 탄소(C-7, δ125), 4차 탄소(C-6, δ74.4), C-5(δ37)과 커플링되어 있어 4차 탄소와 결합하고 있음을 예측하였으며 다른 메틸기 수소(H-13, δ1.2)는 4차 탄소(C-2, δ74.5), C-1(δ29.6)와 커플링하고 있어 C-2와 결합하고 있음을 확인하였다. 또한 H-1(δ2.3)는 C-3(δ75.5), C-7(δ125)와, H-4(δ1.16)은 C-6(δ74.4), H-5(δ2.02)는 C-3(δ75.5)와 커플링하고 있어 C-1부터 C-8은 거대고리를 형성하고 있음을 예상하였다. 또한 C-2와 C-6은 단일결합 형태의 4차 탄소임에도 불구하고 케미컬 쉬프트가 저자장으로 이동한 것으로 보아 전기음성도가 큰 원소가 결합했음을 예상하였다. 따라서 NMR 스펙트럼을 분석한 결과 분리된 화합물은 1개의 β-glucose와 벤젠고리, 8각 다환고리로 구성되어 있음을 확인하였고 예상구조를 문헌 검색한 결과 기존에 보고되지 않은 신규물질임을 밝혀 <화학식 1>의 신규물질인 Multioside로 명명하였다.In the H-H COSY spectrum (FIG. 5), it was confirmed that the protons (H-11, δ6.40) of the benzene ring and the protons (H-15, δ2.2) of the methyl group were coupled. Therefore, the H-15 methyl group is bound to the benzene ring, and HSQC spectrum and HMBC spectrum (FIG. 7) analysis results (FIG. 6) anomer hydrogen (H-1 ', δ 105) and benzene ring carbon (C-9, δ 146). The coupling of was confirmed. The methyl group linked to the benzene ring was coupled with C-9 (δ146), C-10 (δ129), and C-11 (δ116), which was expected to bind with C-10. In addition, hydrogen (H-11, δ6.4) of the benzene ring couples with C-9, C-12, and C-7, respectively, and with C-9 and C-7, ortho, C-12, meta, C It was confirmed that -8 is in the para position. Methyl hydrogen (H-14, δ1.7) is coupled to benzene ring carbon (C-7, δ125), quaternary carbon (C-6, δ74.4), and C-5 (δ37) And other methyl hydrogens (H-13, δ1.2) are coupled with quaternary carbons (C-2, δ74.5) and C-1 (δ29.6). It was confirmed that the binding. H-1 (δ2.3) is C-3 (δ75.5), C-7 (δ125), and H-4 (δ1.16) is C-6 (δ74.4) and H-5 (δ2). .02) is coupled to C-3 (δ75.5), and C-1 to C-8 are expected to form macrocycles. In addition, although C-2 and C-6 are quaternary carbons in the form of a single bond, the chemical shift shifted to the low field, suggesting that elements with high electronegativity were bound. Therefore, NMR spectrum analysis showed that the isolated compound was composed of one β-glucose, a benzene ring, and an octagonal polycyclic ring, and the expected structure revealed that it was a novel substance that was not previously reported. It was named Multioside, a novel substance of>.
분리된 물질의 분자량을 측정하기 위해 HR-FABMS 분석을 실시했다. 신규물질의의 분자량은 426.46이며 HR-FABMS 분석 결과 소듐이 결합된 형태인 449.1791(Calcd for C21H30O9Na: 449.1788)로 분석되어 예상한 분자구조가 정확함을 확인하였다.HR-FABMS analysis was performed to determine the molecular weight of the isolated material. The molecular weight of the new material was 426.46 and HR-FABMS analysis showed 449.1791 (Calcd for C 21 H 30 O 9 Na: 449.1788) in the form of sodium to confirm that the expected molecular structure was accurate.
