활성산소의 하나인 과산화수소(hydrogen peroxide, $H_2O_2$)에 대한 세포독성과 이에 대한 연꽃수술(Nelumbo nucifera stamen, NNS)추출물의 항산화효과 및 멜라닌화에 미치는 영향을 알아보기 위하여 세포부착율 (cell adhesion activity, CAA)을 비롯한 티로시나제활성저해능 및 총멜라닌합성량을 분석하였다. 본 실험 결과 hydrogen peroxide($H_2O_2$)는 배양 인체피부흑색종세포 (SK-MEL-3)의 CAA를 유의하게 감소시킴으로서 세포독성효과를 나타냈다. 이에 대하여 NNS추출물은 $H_2O_2$의 산화적 손상에 의하여 감소된 CAA를 유의하게 증가시킴으로서 항산화효과를 나타냈다. 한편, $H_2O_2$에 대한 NNS추출물의 멜라닌화에 대한 영향에 있어서 NNS추출물은 $H_2O_2$에 의하여 활성화된 티로시나제활성과 총멜라닌합성량을 감소시킴으로서 멜라닌화에 대하여 억제효과를 나타냈다. 이상의 결과로 부터 $H_2O_2$는 배양 인체피부흑색종세포에 고독성을 나타냈으며 NNS와 같은 식물추출물은 $H_2O_2$와 같은 활성산소에 의한 산화적 손상 및 멜라닌화를 방어하는데 효과적인 것으로 나타났다.

To evaluate the antitumor activity and antimetastatic effects of Kamigumgusingihwan(KGSH) studies have ken done. The results were obtained as follows: 1. KGSH extracts exhibited a weak cytotoxicity against A549, SK-OV-3, B16-F10, and SK-MEL-2 cell lines. But exhibited potent cytotoxicity against P388 cell line in a dose-dependent manner. 2. The concentration inhibiting adhesion of A549, to complex extracellular matrix up to below 30% of control was recognized at $10^{-3}g/ml$ of KGSH 3. KGSH extracts showed a weak inhibitoty effect on DNA topo-isomerase I from calf thymus. 4. The T/C% was 137% in KGSH treated group in S-180 bearing ICR mice. 5. In pulmonary colonization assay, a number of colonies in the lungs were decreased significantly in KGSH treated group as compared with control group. 6. In hematological changes in B16-BL6 injected C57BL/6, numbers of WBC were decreased insignificantly in KGSH treated groups, and also those of platelet were increased insignificantly in KGSH treated groups as compared with control. 7. In CAM assay, KGSH extracts inhibited angiogenesis at $15{\mu}g/egg $concentration significantly as compared with control. Taken together these results, it is strongly demonstrated that KGSH significantly suppressed tumor metastasis by blocking cell adhesion to extracellular matrix. Therefore, KGSH is expected to be clinically a potent antimetastatic drug for the prevention and treatment of cancer.

The methanol extract of the seed of Myristica fragrans (myristicaceae) demonstrated a potent inhibition on the proliferation of cultured human tumor cells such as A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2(melanoma), XF498 (central nerve system) and HCT-15(colon). The MeOH extract was fractionated into three portions by serial solvent partition i,e., EtOAc soluble part, BuOH soluble part and remaining water layer. Among them, the EtOAc soluble part of the extract demonstrated a potent inhibition on the proliferation of cultured human tumor cells, Bioassay-guided fractionation of the EtOAc soluble part led to the isolation of six lignan constituents, i.e., safrole(1), machilin A (2), licarin B (3), macelignan (4), mesodihydroguaiaretic acid (5) and myristargenol A (6) as well as a large amount of myristic acid as active ingredients. Structures of the isolated active components (1-6) were established by chemical and spectroscopic means.

The inhibitory effect of omega-3 such as linolenic acid (LNA), docosahexaenoic acid (DNA) and eicosapentaenoic acid(EPA) on the growth of normal cell lines and cancer cell lines was evaluated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyItetrazolium bromide (MTT) and 2,3-bis-2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-caboxanilide (XTT) methods. LNA was found to decrease the cell viability of human oral epithelioid carcinoma cells (KB) in the MTT assay, whereas EPA appeared to inhibit the cell adhesion activity of human skin melanoma cells (SK-MEL-3) in the XTT assay analysis. DPPH radical scavenging activity was examined on LNA, DHA and EPA at the concentration of 100 ${\mu}M$, where they showed about 53% scavenging activity. These results suggest that omega-3 unsaturated fatty acid has a potential anticancer activity.

It is demonstrated that phenolic compound has cytotoxic effect on cancer cells. Recently, ferulic acid is involved in anticancer activity by showing the decrease of cell viability in cancer cells. But, the anticancer mechanism of ferulic acid is left unknown. The purpose of this study was to examine the anticancer activity of ferulic acid on NIH3T3 fibroblasts and human skin melanoma cells (SK-MEL-3). The anticancer activity was measured by determining the cytotoxicy of ferulic acid on these cells. The cytotoxicity was measured by cell viability via XTT assay in these cells. In this study, ferulic acid decreased cell viability according to the dose-dependent manners after human skin melanoma cells were treated with various concentrations of ferulic acid for 48 hours. especially, ferulic acid remarkably decreased cell viability at a concentration of $120{\mu}M$ compared with control in human skin melanoma cells. While, ferulic acid did not show the significant decrease of cell viability at concentrations of $30{\sim}120{\mu}M$ in NIH3T3 fibroblasts. These results suggest that ferulic acid showed anticancer activity in cancer cells such as human skin melanoma cells by the decrease of cell viability significantly.

A bioassay-guided fractionation of the whole extract of Viscum album var. coloratum Ohwi (Loranthaceae) led to the isolation of two triterpenoidal components; oleanolic acid (1) and ${\beta}-amyrin$ acetate (2), and a flavonoid, homoflavoyadorinin B (3) as well as large quantity of free fatty acid mixtures as active ingredients of the extract responsible for the antitumoral property. The EtOAc soluble fraction and BuOH soluble fraction of the extract demonstrated a significant inhibition on the proliferation of cultured human tumor cells such as A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system), and HCT-15 (colon) in vitro, whereas the remaining water soluble fraction exhibited a poor inhibition. The intensive phytochemical investigation of the EtOAc soluble fraction and BuOH soluble fraction of the extract indicated that the oleanolic acid (1) and large amounts of free fatty acid mixtures might be attributed to the in vitro antitumoral property of the whole extract of Viscum album var. coloratum.

Myxobacterium sp. HK1, isolated from Korean soil, degrades cellulose, differentiates to fruiting body, and its 16s rDNA has $95\%$ similarity to Polyangium sp. An anticancer molecule, CDMHK, was identified from culture broth of Myxobacterium sp. HK1, and purified by Diaion HP20, Silica gel, Sephadex LH-20 chromatography, and preparative HPLC using an YMC OSD-A C18 column. The molecular structure and formula were determined to be $C_{l2}H_{l9}N_3O_2$ (M.W 237) by MS spectrometry, 300 MHz $^{1}H\;and\;^{13}C$ NMR. The CDMHK was not active against Escherichia coli, Staphylococcus aureus, and Candida albicans. However, this molecule inhibited the growth of various cancer cell lines. The $ED_{50}$ values of CDMHK were determined to be 0.147, 0.086, 0.18, 0.166, and 0.142 $\mu$g/ml against A549, SK-OV-3, SK-MEL-2, VF498, and HCTl5 cancer cell lines, respectively. In addition, the CDMHK was able to induce apoptosis of the CCRF-CEM cancer cell line, evidenced by DNA fragmentation assay and DAPI staining.
