본 연구에서 동의보감에 기록된 유암 치료에 사용되어온 5가지 한약재 처방전인 십육미류기음, 단자청피탕, 지패산 Ⅰ, 지패산 Ⅱ와 청간해울탕의 열수와 에탄올 추출물에 대한 총 페놀 함량의 비교 분석과 항산화능 및 항균활성능을 비교 조사하였다. 열수와 70% 에탄올 추출물의 수율은 각각 지패산 Ⅱ와 단자청피탕이 가장 높았으며, 총 페놀 함량은 다른 한약재에 비해 단자청피탕이 가장 높았다. 열수 추출물의 총 페놀 함량은 지패산 Ⅰ < 청간해울탕 < 지패산 Ⅱ < 십육미류기음 < 단자청피탕 순으로 높게 나타났다. 70% 에탄올 추출물의 총 페놀 함량은지패산 Ⅱ < 지패산 Ⅰ < 청간해울탕 < 십육미류기음 < 단자청피탕 순으로 풍부하였다. 그 중 단자청피탕과 십육미류기음의 환원력과 DPPH radical과 ABTS radical 소거능이 가장 뛰어났으며, 이들 시료의 총 페놀 함량과 그들의 항산화능과의 밀접한 상관도가 관찰되었다. 또한 Staphylococcus aureus 및 Escherichia coli에 대한 항균활성은 열수보다 70% 에탄올 추출물에서 효과가 높게 관찰되었다. 결론적으로 유암의 치료에 사용되었던 조사 대상 한약재 처방전은 항산화와 항균 활성은 그들의 총 페놀 함유량과 연관성이 높았으며, 본 연구의 결과는 각 처방전에 대한 구체적인 생리활성 비교를 위한 자료로서 활용될 것이다.

Objectives : We compared the inhibitory effects of herb-combined remedies, which were recorded on "Yooam" prescription of Dongeuibogam, on cell migration and invasion, two critical cellular processes that are often deregulated during metastasis, in B16F10 melanoma cells. For this purpose, water extracts of Sipyukmiryukieum (SYMRKU), Danjacheongpitang (DJCPT), Cheongganhaeultang (CGHUT) and Jipaesan (JPS) were used. Methods : Cytotoxicity was assessed by an MTT assay. Wound healing and matrigel transwell assays were used to examine on B16F10 cell migration and invasion. The levels of mRNA and protein expression of matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) were analyzed by RT-PCR and Western blotting. Results : Our data showed that DJCPT showed the strongest inhibitory effect among the four prescriptions in inhibiting cell motility of B16F10 melanoma cells within the concentration range that was not cytotoxic. The inhibitory potential of colony formation was higher in DJCPT and SYMRKU compared to the other two types of prescriptions, and the inhibitory effect of invasiveness is shown in order of DJCPT, SYMRKU, CGHUT and JPS. DJCPT, and SYMRKU strongly inhibited the activity and expression of MMP-2 and MMP-9, which are important mediators in cancer invasion, compared to CGHUT and JPS, and the increased expression of TIMP-1 and TIMP-2 was also more effective in these two prescriptions. In conclusion, DJCPT is expected to exhibit the most potent blocking effect on migration and invasion among four herb-combined remedies compared in B16F10 melanoma cells. Conclusion : Overall, the results of this study will be used as an important source to validate these prescriptions in animal models and to understand the mechanism of action of herbal remedies recorded in Dongeuibogam.

본 연구에서, 우리는 동의보감에서 옹저에 대한 한약재 처방전인 길경탕(GGT), 대황목단탕(DHMDT), 사간탕(SGT), 소청룡탕(SCRT), 시호청간탕(SHCGT), 십육미류기음(SYMYKE) 과 황흑산(HHS)에 대한 항산화능과 항암과 항균활성에 대한 생리활성에 대한 연구를 수행하였다. 총 페놀 함량은 길경탕 ＜ 십육미류기음 ＜ 소청룡탕 ＜ 시호청간탕 ＜ 대황목단탕 ＜ 사간탕 ＜ 황흑산의 순서대로 함량이 풍부하였다. 이들 중 황흑산은 SOD 유사활성, 환원력과 DPPH 라디칼과 ABTS 라디칼의 소거능이 가장 뛰어났다. 흥미롭게도, 이들 시료의 총페놀 함량과 그들의 항산화능과의 상관도는 높게 나타났다. 모든 시료에서 인간대장세포인 HCT-116에서 항암활성을 나타냈으며, 특히 황흑산은 가장 낮은 활성을 나타낸 길경탕보다도 7배 높은 항암활성을 보였다. 또한, 대장균인 Escherichia coli와 위염을 발생시키는 Helicobacter pylori 균에 대한 항균 활성을 시행한 결과 사간탕, 소청룡탕, 십육미류기음과 황흑산에서 항균활성이 보였다. 결과를 종합하여 볼 때, 한약재 처방전은 항산화와 생리활성물질의 소재로서의 가치가 있음을 알 수 있었다.

Objectives : We selected three herb-combined remedies, Bigihwan (BGH), Daechilgitang (DCGT) and Mokwhyangbinranghwan (MHBRH), through Donguibogam text-mining analysis, and evaluated their anti-cancer effects on human hepatocellular carcinoma Hep3B cells. Methods : Cytotoxicity was assessed by an MTT assay. Apoptosis rate, autophagy and ROS level were detected by flow cytometry. The autophagy was also observed by Cyto-ID staining fluorescence microscopy. The expression of autophagy, mitophagy and pexophagy regulatory proteins was detected by Western blot analysis. Results : BGH showed the strongest effect among the three prescriptions in inhibiting Hep3B cell viability, which was associated with the induction of apoptosis and autophagy. Autophagy blockers improved cell viability and reduced apoptosis after BGH and DCGT treatments, indicating that autophagy by these prescriptions enhanced Hep3B cells against their cytotoxicity. However, MHBRH enhanced the reduction of cell viability and apoptosis by autophagy blockers. Induction of autophagy by BGH treatment was associated with mitophagy due to mitochondrial dysfunction than DCGT and MHBRH-treated cells. In addition, induction of apoptosis by BGH treatment was ROS-dependent and showed the possibility of pexophagy involvement. Conclusion : Although further studies need to be conducted to study the efficacy and mechanism of accurate anticancer activity, the present results will serve as important sources of understanding the mechanism of action of herbal remedies prescribed for liver disease as documented in Donguibogam.
