  • 인삼(Panax. ginseng) 열매를 80% MeOH 수용액으로 3회 반복 추출한 뒤, 감압 농축한 추출물을 EtOAc, n-BuOH과 $H_2O$ 층으로 계통 분획을 실시하였다. EtOAc분획에 대하여 $SiO_2$ 및 ODS column chromatography를 반복실시하여 5종의 ginsenoside 화합물을 분리 및 정제하였다. NMR, IR, FAB/MS 데이터를 해석하여, 각각 ginsenoside F1 (1), ginsenoside F2 (2), ginsenpside F3 (3), ginsenoside Ia (4) 및 notoginsenoside Fe (5)로 구조 동정 하였다. 화합물 2-5는 인삼열매에서는 이번에 처음 분리 보고되었다. 분리한 5종의 화합물을 인체 암세포주(HCT-116, SK-OV-3, HeLa, HepG2, SK-MEL-5)에 처리하여 세포독성을 측정하였다. 이 중 화합물 2, 4, 및 5가 인체 암세포주에 대해 세포독성을 저해시키는 것을 알 수 있었다. 화합물 2는 SK-MEL-5, HepG2, HeLa세포에서 $IC_{50}$값이 82.8, 86.8, $78.3{\mu}M$로 확인되었다. 화합물 4는 HCT-116, SK-MEL-5, SK-OV-3, HepG2, HeLa 세포에서 $IC_{50}$ 값이 24.5, 25.4, 26.3, 22.0, $24.9{\mu}M$로 확인되었다. 화합물 5는 SK-MEL-5 세포에서 $IC_{50}$ 값이 $81.7{\mu}M$로 확인되었다. 인삼 열매에서 분리한 화합물2, 4, 및 5가 암세포주에 대해 강한 세포독성을 나타내는 것을 확인하였으며, 이 화합물들은 공통적으로 3번 수산기에 glucopyranose를 가지고 있음을 확인하였다.

  • In our continuing search for new antineoplastic agents from natural products, one hundred and thirty-five herbal drugs were extracted with petroleum ether/ether (1:1), ethyl acetate and methyl alcohol, successively and their cytotoxicities were evaluated against A549 (human lung carcinoma) and SK-OV-3(human ovary adenocarcinoma) cell lines. Among them, fifteen kinds of ether extracts, eighteen kinds of ethyl acetate extracts and seven kinds of methanol extracts showed significant cytotoxic activities (above 70% inhibition) against A549 cell lines at a concentration of $40\;{\mu}g/ml,$ while ten kinds of ether extracts, thirteen kinds of ethyl acetate extracts and six kinds of methanol extracts demonstrated significant cytotoxic activities against SK-OV-3 cell lines at the above same concentration.

  • This study investigated the proapoptotic effect of ethanol extracts obtained from dandelion (Taraxacum officinale) flower on human ovarian cancer SK-OV-3 cells. Cells were treated with dandelion flowers ethanol extract (DFE) ranging from 1.5625 to $100{\mu}g/mL$ for 24 hr. Significant antiproliferative effects of DFE were first observed from at $6.25{\mu}g/mL$ (p<0.05), and this inhibition showed in a dose-dependent manner. When cells were treated with more than $6.25{\mu}g/mL$ DFE, cell-cycle analysis showed that DFE caused an increase in the percentage of sub-G0/G1 cells and arrested at the S and G2/M phase in a dose-dependent manner. Moreover, apoptosis induction by DFE involved p53 activation and bax upregulation as well as downregulation of bcl-2. Our findings indicate that DFE resulted in apoptotic cell death, suggesting that DFE possesses potential anticancer properties.

  • To evaluate the antitumor activity and antimetastatic effects of Polygoni Orientalis Fructus(POF), studies were done experimentally. The results were obtained as follows : 1. In cytotoxicity against A549, and XF498 cell concentration inhibiting cell growth up to below 30% of control was recognized at $200{\mu}g/m{\ell}$ of POF. Also POF inhibited cell growth up to below 30% of control against SK-OV-3, SK-MEL-2, HCT15 and MCF-7 cell at $100{\mu}g/m{\ell}$. 2. The concentration inhibiting adhesion of A549 and SK-OV-3 to complex extracellular matrix up to below 70% of control was recognized at $100{\mu}g/m{\ell}$ of POF. 3. In pumonary colonization assay, a number of colonies in the lungs were decreased significantly in POF treated group as compared with control group. These results suggested that POF extracts might be usefully applied for prevention and treatment of cancer.

  • Previously, we reported that lysophosphatidylethanolamine (LPE), a lyso-type metabolite of phosphatidylethanolamine, can increase intracellular $Ca^{2+}$ ($[Ca^{2+}]_i$) via type 1 lysophosphatidic acid (LPA) receptor ($LPA_1$) and CD97, an adhesion G-protein-coupled receptor (GPCR), in MDA-MB-231 breast cancer cells. Furthermore, LPE signaling was suggested as like $LPA_1/CD97-G_{i/o}$ proteins-phospholipase $C-IP_3-Ca^{2+}$ increase in these cells. In the present study, we further investigated actions of LPE not only in the $[Ca^{2+}]_i$ increasing effect but also in cell proliferation and migration in MDA-MB-231 breast cancer cells. We utilized chemically different LPEs and a specific inhibitor of $LPA_1$, AM-095 in comparison with responses in SK-OV3 ovarian cancer cells. It was found that LPE-induced $Ca^{2+}$ response in MDA-MB-231 cells was evoked in a different manner to that in SK-OV3 cells in terms of structural requirements. AM-095 inhibited LPE-induced $Ca^{2+}$ response and cell proliferation in MDA-MB-231 cells, but not in SK-OV3 cells, supporting $LPA_1$ involvement only in MDA-MB-231 cells. LPA had significant effects on cell proliferation and migration in MDA-MB-231 cells, whereas LPE had less or no significant effect. However, LPE modulations of MAPKs (ERK1/2, JNK and p38 MAPK) was not different to those by LPA in the cells. These data support the involvement of LPA1 in LPE-induced $Ca^{2+}$ response and cell proliferation in breast MDA-MB-231 cells but unknown GPCRs (not $LPA_1$) in LPE-induced responses in SK-OV3 cells. Furthermore, although LPE and LPA utilized $LPA_1$, LPA utilized more signaling cascades than LPE, resulting in stronger responses by LPA in proliferation and migration than LPE in MDA-MB-231 cells.

  • A minor cytotoxic compound was isolated by bioassay-guided fractionation from Asiasari Radix and identified as aristolactam III(1) on the basis of spectral data and chemical evidence. This is the first report on the isolation of compound 1 from Asiasarum genus. Compound 1 exhibited a significant cytotoxic activity against the three kinds of human cancer cell lines (A 549, SK-MEL-2 and SK-OV-3).
