This study was carried out to evaluate cytotoxicity of the extracts from Sophora flavescens Ait. against L1210 (lymphocytic leukemia) and $P388D_1$ (lymphoid neoplasms) cells in vitro. We have determined cytotoxicity by MTT {3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazo-liumbromide} assay. The order of cytotoxicity of Sophora flavescens Ait. extracts against L1210 and $P388D_1$ cells in vitro is as follows: AM> EASF > CFSF > MTSF > WSF > HXSF and AM> EASF> CFSF> MTSF> HXSF> WSF. These results suggest that the ethyl acetate soluble extract of Sophora flavescens Ait may be a valuable choice for the development of antitumor agents.

The effects of crude extracts from medicinal plants on biological activity were investigated. The crude ethanol extract of H. paucistipula inhibited the growth of the Gram positive bacterium Bacillus subtilis ATCC 19659, (2 mm inhibition zone at 150 ㎍/disc) and the dermatophyte Trichophyton mentagrophytes ATCC 28185, (7 mm inhibition zone at 150 ㎍/disc), and toxic to P388 murine leukaemia cells ATCC CCL 46 P388D1, (IC/sub 50/ 2.48 ㎍/㎖ at 75 ㎍/disc). This crude ethanol extract of H. paucistipula is the strongest antimicrobial and cytotoxic activities against P388 murine leukaemia cells ATCC CCL 46 P388D1.

생체내 중요한 면역조절물질의 하나인 IL-l은 주로 Macrophage로부터 분비되어 각종 면역반응에 관여하는 것으로 알려져 있는데 이러한 Macrophage에 의한 IL-I 생성에 미치는 Histamine의 효과를 검토하고자 Mac-rophage-like cell line인 $P388D^1$세포에 의한 IL-1생성에 미치는 Histamine의 첨가효과는 $10^-^8M~10^-^3M$에 이르기까지 전 범위에서 농도의존적으로 IL,-1생성을 촉진시켰으며 첨가후 배양시간에 있어서는 24~36시간이 가장 크게 상승되었다. Histamine에 의한 Macropahge로 부터의 IL-1생성은 EGTA 및 $Co^2^+$의 첨가로 인하여 농도의존적으로 저하되었으며 이 결과는 Histamine의 IL-1 생성촉진작용이 세포내로의 $Ca^2^+uptake가 signal 역할을 하고 있음을 시사한다. $P388D_1$세포로의 $Ca^2^+$uptake양을 동정한 결과는 Histamine의 $10^-^7M$에서 $10^-^3M$까지 농도의존적으로 $Ca^2^+3M$유입이 촉진되는 결과를 나타내었다.

This study was carried out to evaluate cytotoxic effects of the roots of Sophora flavescens Ait. extracts on murine leukemia tumor cells lines $(P388D_1\;and\;L1210)$. Disruptions in cell organelles were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The comparison of $IC_{50}$ values of the ethyl acetate of Sophora flavescens Ait. extract in leukemia cell lines showed that their susceptibility to these extracts decreased in the following order : Adriamycin>Fr.4>Fr.5>Fr.3>Fr.1>Fr.2 by the MTT assay. These results suggest that the fraction 4 of the ethyl acetate soluble extract of Sophora flavescens Ait. may be a valuable choice for the studies on the treatment of murine leukemia cell lines.

The effects of crude extracts from medicinal plants on biological activity were investigated. The crude ethanol extract of H. paucistipula inhibited the growth of the Gram positive bacterium Bacillus subtilis ATCC 19659, (2 mm inhibition zone at 150 ${\mu}g$/disc) and the dermatophyte Trichophyton mentagrophytes ATCC 28185, (7 mm inhibition zone at 150 ${\mu}g$/disc), and toxic to P388 murine leukaemia cells ($IC_{50}\;2.48\;{\mu}g/ml$ at 75 ${\mu}g$/disk). This crude ethanol extract of H. paucistipula is the strongest antimicrobial and cytotoxic activities against P388 murine leukaemia cells (ATCC CCL 46 P388D1).

4-Geranyloxy compound (1) has elucidated by spectroscopic analysis. This compound (1) inhibited the growth of the dermatophytic fungus Trichophyton mentagrophytes ATCC 28185, (2 mm inhibition zone at 15 ㎍/disc), cytotoxic to P388 murine leukaemia eel/lines ATCC CCL 46 P388D1, (IC/sub 50/ 1,125 ng/ml at 7.5㎍/disc) and BSC monkey kidney cell lines (100% of well at 15 ㎍/disc).

A new isoprenylated acetophenone, acronyculatin P (1) as well as two known compounds, 3',5'-diisoprenyl-2',4'-dihydroxy-6'-methoxyphenylethanone (2) and 3'-isoprenyl-2',4',6'-trihydroxyphenylethanone (3) were isolated from the stem bark of Acronychia pedunculata (L.) Miq. The structures were determined by HRESIMS, 1D and 2D NMR. The inhibitory activity of the isoprenylated acetophenone derivatives against murine leukemia P-388 cells showed compound 1 moderate activity with $IC_{50}$ $15.42{\mu}M$.

In an effort to enhance the lipophilicities, thereby, the penetration into the cell membrane and to increase the antitumor activities of modified derivatives of 2',3'-didehydro-3'-deoxythymidine (d4T, 1), derivatives of 1 were designed and synthesized. Starting from thymidine, 1, 2',3'-didehydro-3'-deoxythymidine-5'-phosphate, disodium salt (d4T-p, 7), and two nicotinate esters of 1; 2',3'-didehydro-3'-deoxy-5'-O-(3-pyridinylcarbonyl)thymidine (d4T-NA, 5) and 2',3'-didehydro-3'-deoxy-5'-phosphoryl-O-(3-pyridinylcarbonyl)thymidine (d4T-p-NA, 8) were synthesized. The lipophilicities of the synthesized compounds were measured by P-values and antitumor activities of those were estimated against mouse leukemia P388, murine mammary carcinoma FM3A, and human histiocytic lymphoma U937 tumor cells in vitro. Although the lipophilicities of the nicotinate esters, 5 and 8 were increased 2.75- and 9.71-fold relative to that of 1 and 7, respectively, the synthesized compounds, 1, 5, 7, and 8 were found to be inactive against P388 and FM3A cells except weak antitumor activity against U937 cell.

To investigate the cytotoxicity of Korean traditional fermented soybean products using the MTT assay, we extracted soybean, Kanjang, Doenjang, Kochujang, and Chongkukjang with water, methanol, and hexane. Primary testing of cytotoxicity of 14 extracts was done for P388D1(mouse lympoid neoplasm) and L1210(mouse leukemia) cell lines. Doenjang methanol extract, Kochujang hexane extract, Chongkukjang methanol extract, and Chongkukjang hexane extract showed cytotoxicity of 86.1, 94.3, 83. 6, and 81.1%, respectively against P388D1, and showed cytotoxicity of 69.4, 96.9, 51.4, and 95.1%, respectively against L1210. All the other extracts showed less than 50% cytotoxicity. Methanol extracts of Doenjang and Chongkukjang showed dose-dependent cytotoxicity against P388DI, L1210, SNU-16 (human stomach cancer), HepG2(human hepatic cancer), WiDr(human colon cancer) cell lines, and IC$_{50}$ of Doenjang methanol extract was 67.7, 90.4, 1338.0, 706.4, and 371.2 $\mu$g/ml, respectively, and IC$_{50}$ of Chongkukjang methanol extract was 107.1, 228.3, 756.2, 1346.0, and 327.0 $\mu$g/ml, respectively.

During a survey of new antitumor substances from higher plants, we have found that the crude extract of Simaba cedron Planchon (Simaroubaceae) showed cytotoxic activity (IC$\sub$50/ 0.7 $\mu\textrm{g}$/mL) against P388 leukemia cells. Activity-guided chromatographic purification using P388 cells led to the isolation of five novel quassinoids, cedronolactones A-E (1-5) and nine known quassinoids, simalikalactone D (6), chaparrinon (7), chaparrin (8), glaucarubolone (9), glaucarubol (10), samaderine Z (11), guanepolide (12), ailanquassin A (13), and polyandrol (14). In this seminar, the structural elucidation of 1-5 and the cytotoxic activity of the isolated compounds are discussed.
