식용식물 섬바디에서 분리한 falcarindiol과 monoglyceride (MG)와의 상승효과를 실험하였다. Falcarindiol 30 ppm 및 10 ppm과 MG 25 ppm, 10 ppm을 각각 배지에 첨가하여 Lm 5균주에 대한 혼탁도를 비교한 결과 4개의 처리구에서 시험된 모든 균에 대하여 혼탁도가 나타나지 않았다. 이 결과로 falcarindiol과 monoglyceride의 혼합물의 살균효과가 기대되어, Tryptic soy broth에 혼탁도 비교시 사용한 동일 농도를 첨가한 후, Lm 2균주(ATCC 19111, ATCC 19114)를 배양시켜 24시간 간격으로 생균수를 확인한 결과 대조구는 초기 $10^5{\sim}10^6\;CFU/mL$에서 72시간 배양결과 2 log cycle 증가하는 반면, 처리구는 72시간 배양결과 colony를 발견할 수 없었다. 이 결과를 볼 살균효과가 인정되었다. 이상의 결과로 섬바디로부터 분리된 falcarindiol과 monogyleride와의 혼합물은 살균효과가 단독 사용시보다 상승하였고, 합성 항균제보다 우수한 천연 항균제로서의 가능성이 있다고 평가된다.

A methanol extract of the root of Peucedanum japonicum, used as a medicinal herb, showed an inhibitory effect on mammalian topoisomerase I activity. The methanol extract was suspended in ethyl acetate, and a topoisomerase I inhibitor in the organic soluble fraction was then isolated by silica gel and thin layer chromatography. The topoisomerase I inhibitory compound was indentified as falcarindiol based on the analysis of EI-MS, $^1$H and \ulcornerC NMR spectroscopy. This inhibitory showed cytotoxicity against human leukemia Jurkat T and HL60 cells with an IC\ulcorner value of 7 $\mu\textrm{g}$/ml. These results suggest the possibility of falcarindiol as a new anticancer agent which can be expected to have a synergistic effect on other anticancer drugs. In addition, the present data show that falcarindiol has antifungal, yet not antibacterial, activity.

An n-hexane extract of the roots of Aralia cordata Thunb. (Araliaceae) was found to show significant in vitro cytotoxic activity against P388D$_{1}$ lymphocytic leukemia cell in culture. Bioactivity-directed fractionation of this extract led to the isolation of four polyacetylenes, falcarindiol (1), dehydrofalcarindiol (2), falcarindiol-8-acetate (3) and dehydrofalcarindiol-8-acetate (4). Cytotoxicity of compounds 1 and 3 was found to be better than that of compounds 2 and 4 when these compounds were tested against eight in vitro tumor cell lines, namely, A549, HCT15, DLD1, MCF7, SKOV3, HL60, K562 and P388D$_{1}$. The fact that the cytotoxicity of compounds 1 and 3 against series of tumor cell lines was much stronger than that of compounds 2 and 4 suggested that the saturated carbon chain at the termial and the hydroxyl group at the C-3 are important for the activities. The requirement for the activity was further confirmed by synthesizing and assaying the acetate derivatives of compounds 1 and 2.

Four hundred varieties of plant extracts were screened for inhibitory activity against the NFAT transcription factor which plays an important role in inducing immune response. Among them, the MeOH extract of Cnidium officinale showed potent activity, and the activity-guided separation yielded butylidenephthalide, senkyunolide A and falcarindiol as the active constituents. The $IC_{50}$ value of butylidenephthalide was $1.3{\times}10^{-4}\;M$ and was similar to that of senkyunolide A $(2.1{\times}10^{-4}\;M)$. Interestingly, falcarindiol showed higher activity $(IC_{50},\;2.6{\times}10^{-5}\;M)$ than the two phthalides.

The MeOH extract of Notopterygium incisum showed a strong cytotoxicity against B16 murine melanoma cell line. From this extract three furanocoumarins including bergamottin, isoimperatorin, notopterol and one polyacetylenic compound (falcarindiol) together with one phenylpropanoid (caffeic acid methyl ester) and one triterpenoid (pregnenolone) were isolated. The isolated compounds were evaluated for cytotoxic activity against four kinds of cancer cell lines, e.g. P388 (murine lymphocytic leukemia), B16 (murine melanoma), A549 (human lung carcinoma) and SK-OV-3 (human ovarian cancer). Among the isolates, falcarindiol and caffeic acid methyl ester expressed a significant antiproliferative activity against all tested cell lines.

Angelica koreana is an important medicinal plant for some locals in East Asia including Korea. A few reports have shown the efficacy of its phytochemical constituents. We have isolated and purified one compound falcarindiol (FAL) from the methanolic extract of A. koreana roots. At concentrations from to $1{\mu}M$ to $25{\mu}M$, the FAL isolated from the roots of A. koreana exerted no significant cytotoxicity and down-regulated LPS-stimulated pro-inflammatory cytokine IL-8 in colon epithelial cells, while up-regulating anti-inflammatory cytokine IL-10. In addition, the FAL decreased the expression of LPS-induced inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 protein by Western blot analysis. Colon epithelial cells play pivotal roles in regulating the colon immune system and thus FAL is expected to be candidate agent as therapeutic potential for the treatment of inflammatory bowel disease (IBD) by modulating LPS-induced inflammation in colon epithelial cells.

섬바디 75% 에탄올 추출물과 핵산 분획물을 첨가하여 Listeria monocytogenes(Lm) ATCC 19111, ATCC 19112, ATCC 19113, ATCC 19114 및 ATCC 15313에 대한 증식억제 효과와 그 활성 물질의 구조를 확인하였다. 항균효과를 시험한 결과 에탄올 추출물은 50 ppm, 핵산 분획물의 경우에는 30 ppm에서 5종의 Listeria 균주를 모두 증식저해 시켰다. 항균활성이 우수한 섬바디 핵산 분획물을 silica gel column으로 1회 분획하여 획분 A8을 얻었고 이의 항균효과는 대단히 우수하여 10 ppm에서 실험균주 모두를 증식저해 시켰다. A8이 아주 우수한 항균효과를 나타내었기에 살균효과가 기대되었다. Tryptic soy broth에 섬바디 추출물에서 분리된 A8를 30 및 10 ppm씩 배지에 첨가한 후 Lm 5균주를 배양시켜 24시간 간격으로 생균수를 확인한 결과 대조구는 균수가 증가하는 반면 처리구는 균수가 감소함으로서 살균효과가 인정되었다. 그리고 이 획분 A8을 2회 연속 분리하여 단리된 소획분 SBD-1과 SBD-2를 얻었다. 이렇게 단일 물질로 분리된 SBD-1과 SBD-2의 항균효과는 column 분리후 얻은 획분(A8)보다 증식억제 효과가 감소하였는데 이는 섬바디에 존재하는 항균물질은 단독으로 작용하는 것이 아니라 그 안에 있는 여러 물질들의 혼합작용으로 그 효과가 나타난 것이라 추정되었다. 단일물질로 분리된 두 물질 중 수율이 높은 SBD-2를 구조 동정한 결과 폴리아세틸렌 화합물 (9z)-hepta-deca-1,9-dien-4,6-diyn-3,8-diol 인 falcarindiol로 확인되었다. 이 물질은 미나리과 식물 뿌리에 존재한다.

Activity-guided fractionation of the roots of Anthriscus sylvestris resulted in the isolated and characterization of five cytotoxic compounds, deoxypodophyllotoxin (1), falcarindiol (2), and angeloyl podophyllotoxin (5) from the hexane soluble fraction and morelensin (3), bursehernin (4) from the choloroform soluble fraction. It is the first report of the occurrence of compound 5 in nature.
