  • 뉴질랜드의 자생식물인 Brachyglottis monroi와 Trichocolea hatcheri의 에탄올추출물에 대한 생리활성을 조사한 결과, 그람음성균인 Bacillus subtilis (ATCC 19659, 1 mm inhibition zone at $150{\mu}g/disc$)와 피부곰팡이균인 Trichophyton mentagrophytes (ATCC 28185, 6 mm inhibition zone at $150{\mu}g/disc$)에 대한 억제효과가 관찰되었으며, 이들 추출물은 P388 murine leukaemia cells ($IC_{50}$ $23.96{\mu}g/mL$)에서도 세포독성이 나타났다. B. monroi의 에탄올추출물의 항바이러스효과는 T. hatcheri의 에탄올추출물보다 강한 활성이 관찰되었으며, T. hatcheri의 에탄올추출물의 항균효과는 B. monroi의 에탄올추출물보다 강한 활성을 나타났다. 그렇지만 P388 murine leukaemia cells ($IC_{50}>12,500{\mu}g/mL$)에 대한 세포독성은 아주 미미한 것으로 나타났다.

  • Some known coumarins, decursin, nodakenetin, umbelliferone, 7-demethylsuberosin, columbianetin, decursinol angelate and decursinol, showing significant cytotoxic activities against P388 cell lines,were isolated from the roots of Angelica gigas (Umbelliferae) . 7-Demethylsuberosin and columbianetinwere obtained from Angelica gigas for the first time. Chernotaxonornic difference about coumarins com-ponents between the roots of Angelica gigas and those of A. acutiloba is also discussed.

  • Seven flavonoid compounds, kaempferol (1), quercetin (2), quercetin-3-O-${\beta}$-D-glucopyranoside (3), kaempferol-3-O-${\beta}$-D-glucopyranoside (4), kaempferol-3-O-${\alpha}$-L-rhamnoside (5), quercetin-3-O-sophoroside (6) and quercetin-3-O-rutinoside (7), were isolated from the methanolic extract of leaves of Kalanchoe prolifera. Compounds 1-7 were isolated for first time from this plant. These compounds were evaluated their cytotoxic activity against P-388 murine leukimia cells in vitro. Among those compounds kaempferol (1) and quercetin (2) showed strongest cytotoxic activity with $IC_{50}$ values of $4.45{\pm}0.05$ and $6.28{\pm}0.02{\mu}g/mL$, respectively.

  • 한국산 표고버섯(Lentinus edodes SR-1) 균사체를 액체배양한 후 균사체로부터 추출, 정제한 PBP의 항암효과 및 면역학적 특성에 대하여 실험하였다. PBP의 항암효과는 in vitro 배양에서 암세포의 배수시간을 2배로 연장하는 활성단위 1 unit은 mouse leukemic cell인 $P_{388}$$L_{1210}$의 경우 1 mg 정도였으며, 인체의 장암세포인 HCT-48, HRT-18, HT-29 및 간암세포인 Hep G2의 경우 각각 4.4, 3.6, 6.6, 2.6 mg이었다. 그리고 $P_{388}$$L_{1210}$의 경우 배지 1 mL당 4 mg 정도, HRT-18 및 HT-29, Hep G2의 경우 9 mg의 PBP를 첨가했을 때 암세포를 사멸시키는 것으로 나타났다. $P_{388}$$L_{1210}$, HCT-48, Hep G-2의 PBP 처리에 따른 암세포의 크기 분포도 변화는 PBP를 처리하지 않은 대조군에 비하여 시간이 경과함에 따라, 그리고 PBP의 농도가 증가함에 따라 비례적으로 적은 쪽으로 이동하였다. In vivo 실험에서 대조군보다 PBP를 첨가한 군에서 비장의 무게가 증가하였으며, 용혈반 형성실험에서 PBP를 투여한 군이 대조군에 비하여 항체 형성세포가 2배로 증가하였다.

  • A new flavonol derivative, meliglabrin (1) along with three known flavonols, ternatin (2), meliternatin (3), and 5,4'-dihydroxy-3,7,3'-trimethoxyflavon (4) were isolated from the leaves of Melicope glabra (Blume) T.G. Hartley. Their structures were determined using extensive spectroscopic methods, including UV, IR, HRESIMS, 1D and 2D NMR. Compounds 1 - 4 were evaluated for their cytotoxicity against murine leukemia P-388 cells, compound 4 showed moderate activity.

  • A series of 2-alkyl, 2-aryl, and 2-piperazinyl benzimidazole-4,7-dione derivatives (7a-h) and 16m-o) were prepared, and their cytotoxicities were tested against three cancer cell lines (mouse lymphocytic leukemia cell line P388, and human gastric carcinoma cell lines SNU-1 and SNU-16). These compounds showed potent cytotoxicity against all of three cell lines tested, and especially SNU-16 was sensitive to them. 2-Aryl (7g,h) and 2-piperazinyl benzimidazole-4,7-dione derivative (I6 m) were more potent than mitomycin C against P388 and SNU-16. Among benzimidazole-4,7-dione derivatives with alkyl group at position 2, 7a had the most potent cytotoxicity against all of the cell lines tested.

  • The effects of ethanol extract from Lepidolaena clavigera (L. clavigera) on antifungal activity were investigated. The crude ethanol extract of L. clavigera inhibited the growth of the Gram positive bacterium Bacillus subtilis ATCC 19659, (1 mm inhibition zone at 150 ${\mu}g/disc$) and the dermatophytic fungus Trichophyon mentagrophyes ATCC 28185, (2 mm inhibition zone at 150 ${\mu}g/disc$), and cytotoxic to P388 murine leukaemia cells ATCC CCL 46 P388D1, (IC50 >12,500 ${\mu}g/mL\;at\;150\;{\mu}g/disc$) and cytotoxic to BSC monkey kidney cells (@ 5 mg/mL, 150 ${\mu}g/disc$; ++: 50% activity). We suppose that this crude ethanol extract of L. clavigera is the antifungal activity.

  • The objective of this study was to evaluate and compare the antitumor activity of different solvent fractions (ethanol, dichloromethane, ethyl acetate, butanol and water) of the Auricularia auricula-judae 70% ethanol extract on the P388D1 macrophage and sarcoma 180 cells. A dose-dependent antitumor activity of each solvent fraction (from 0.01 mg/ml to 0.3 mg/ml) was shown against both cell types. These cytotoxic effects of all the tested fractions were confirmed on the MTT and SRB assays, without statistical differences each other. $IC_{50}$ value of dichloromethane fraction was 94.2 ${\mu}g/ml$ against sarcoma 180 cells lower than any other solvent fractions. The potent antitumor effect of the dichloromethane (DCM) fraction was also found against solid tumor in BALB/c mice. The splenomegaly and higher splenic index were found in tumor-bearing mice, with the DCM fraction returning to the negative control values. Thus, the results indicated the dichloromethane fraction may have potential ingredients as antitumor candidates.
