The quinone reductase (QR) inducing activities of mung bean and soybean solvent extracts were compared using murine hepatoma cells (Hepa 1c1c7). The mung bean extracts (ethylacetate and ethanol) showed higher chemoprevention index values (7.88-8.22) than those of soybean extracts (2.9-5.2) from four...

Quinone reductase는 무엇이며, 어떤 역할을 하는가? | 99.2)]는 quinine을 hydroquinone으로 전환시키는 중요한 2상효소계의 하나로 glutathione S-transferase(GST)와 함께 cytochrome P-450의 작용에 의하여 유발되는 발암물질의 비활성화 및 배설에 기여한다(3). 지금까지 알려진 많은 항암물질들이 2상효소계의 활성화와 밀접한 관련이 있음이 입증되면서(4) 2상효소계의 활성변화를 이용하여 항암 활성성분의 신속한 탐색이 이루어지고 있으며 브로컬리, 포도, 파, 마늘류로부터 각각 분리 된 sulforaphane, resveratrol, organosulfides 등은 대표적인 2상효소계 유도물질 들이다(5-7). | |
본 연구에서 녹두 및 대두의 용매추출물을 제조하고 hepatoma 1c1c7 세포 및 대식세포인 RAW264.7 배양을 이용하여 항암 및 항염증 효과를 비교분석한 결과는? | 7 배양을 이용하여 항암 및 항염증 효과를 비교분석하였다. 녹두추출물은 대두추출물 보다 ethylacetate 및 ethanol 추출물에서 모두 유의적으로 높은 QR 유도활성과 NO 및 PGE2의 생성 억제 효과를 보였으며 농도 의존적 효과를 나타냈다. C18 silica flash column chromatography를 이용하여 회수된 녹두에탄올 추출물의 7개 분획 중 소수성이 가장 강한 분획은 24 µg/mL의 CD value와 783 µg/mL의 IC50를 보 였다. 현재 다수의 염증 억제물질의 작용기전이 prostaglandin 합성 억제이며 이는 COX-2의 생성 및 활성저해에 의한 것임을 근거로 할 때 녹두의 ethanol 추출물은 항염증 및 암 발생 예방 성분을 분리하기 위한 중요한 식품 자원으로 생각된다. | |
Kennedy(11)는 동물실험 결과를 토대로 대두에 존재하는 어떤 물질이 암발생을 억제하는 효과를 가지고 있다고 보고하였나? | 콩의 섭취에 의한 암 예방 효과는 국내외로 비교적 활발한 연구가 진행된 바 있다. Kennedy(11)는 동물실험 결과를 토대로 대두에 존재하는 단백질 분해효소 억제 물질(Bowman-Birk inhibitor), phytic acid(inositol hexaphosphate), β-sitosterol, saponins 및 isoflavones이 암발생을 억제하는 효과를 가지고 있다고 보고하였다. 국내에서 수행된 동물 실험 결과에 따르면 콩의 메탄올 추출물이 신장과 소장에서 QR의 활성을 유의적으로 증가시키고 benzo(a)pyrene으로 유발시킨 위와 폐암의 발생을 감소시켰다(12). |
