Chitosan is a depolymerized and partially deacetylated derivative of chitin. We investigated the cytotoxicity of chitosan in cancer cell lines, such as P388, L1210, HCT-15, SK-HepG-1 and mouse splenocytes as a normal cell by MTT assay. To clarify whether chitosan enhances cytotoxicity of anticancer drugs, we also examined the cytotoxicity of combined treatment with chitosan and anticancer drugs, such as cisplatin, mitomycin C, and 5-fluorouracil in cancer cell lines in vitro. Chitosan ($37.5\;{\mu}g/mL,\;75\;{\mu}g/mL,\;112.5\;{\mu}g/mL,\;and\;150\;{\mu}g/mL$) showed concentration-dependent cytotoxicity in the cancer cell lines. In addition, chitosan showed relatively lower cytotoxicity in normal cells than in the cancer cell lines. Particularly, this trend was significant at high doses of chitosan, i.e. $112.5\;{\mu}g/mL,\;and\;150\;{\mu}g/mL$. Thus, these results suggest that chitosan may selectively induce the growth inhibition in cancer cell lines, compared to normal cells. Furthermore. the co-treatment of chitosan and anticancer drugs exhibited an apparant synergistic cytotoxicity in murine lymphoma cell lines, i.e. P388 and L1210 at $37.5\;{\mu}g/mL$ of chitosan rather than at $75\;{\mu}g/mL$ of chitosan, but such phenomenon could not be observed in solid tumor cell lines, i.e. HCT-15 and SK-HepG-1. However, chitosan did'nt reduced the cytotoxicity against normal mouse splenocytes induced by anticancer drugs. Therefore, it is concluded that the combination of chitosan and anticancer drugs might be useful for the cancer chemotherapy.

Geranylation of some synthetic and natural flavones have yielded cytotoxic products against L1210 coll; 5,2´-dihydroxy-6,7,8-trimethoxy-6´-geranyloxyflavone 4$(8.5{\mu}g/ml)$, 5,6-dihydroxy-7-gerenyloxyflavone 9$(2.3{\mu}g/ml)$. 2 has showed the same range of cytotoxicity as the starting material, 5,2´-dihydroxy-6,7,8-trimethoxy-6´-benzyloxyflavone$(17.0{\mu}g/ml)$. The cytotoxicity of 4 was lower than its starting substance, 5,2´,6´-trihydroxy-6,7,8-trimethoxyflavone $(4.5{\mu}g/ml)$. On geranylating 5,6,7-trihydroxyflavone(baicalein, $15.0{\mu}g/ml$) the cytotoxic activity has been strongly potentiated($2.3{\mu}g/ml$ of 9). The presence of at least a free hydroxy group in B-ring of Skullkapflavone II-type flavones. was essential for a high activity. A larger RD-group than methoxy in the B-ring has weakened the activity. The cytotoxicities of baicalein series could not be correlated to their structures.

To investigate polyacetylene compounds isolated from petroleum ether extract of panax ginseng effect on the macromolecule synthesis, lympoid lukemia L1210 cell was incubated with them at 4, 8, 12,16 hours. Panaxydol, panaxynol and panaxytriol as cytotoxic substances inhibited the synthesis of macromolecule such as DNA, RNA and protein. Panaxydol which had the most potent cytotoxicity among these three compounds showed the strongest inhibitory effect on DNA, RNA and protein synthesis. For DNA and RNA synthesis, panaxynol and panaxytriol decreased the rate of inhibition with the incubation time but panaxydol had a strongest inhibitory effect at 16 hour incubation time. Protein synthesis was markedly inhibited by all these polyacetylene compounds. It was obserbed that there is a relationship between cytotoxicities of polyacetylene compounds and the inhibition of macromolecule synthesis.

Forty herbal drugs which are described to have potential antitumor activity were solvent-fractionated with petroleum ether, ether and ethyl acetate in sequence. The cytotoxic activity was mostly shown in the ether fraction(40.54%) and petroleum ether fraction (35.15%), but scarcely in the water phase (10.8%), meaning that most of the active components had less polar property. Twenty-seven percent of the drugs tested were active, which is higher value than 10.4% of the random sampled drugs The drugs possessing the $ED_{50}$ values less than $10{mu}g/ml$ were the roots of Lithospermum erythrorhizon, Curcuma domestica, Salvia miltiorrhiza, Astragalus membraneceus and Scutellaria indica, the leaves of Panax ginseng, S. indica and Liriodendron tulipifera, the barks of Picrasma ailanthoides and Rhus vernifera, the herbs of Agrimonia pilosa and Siegesbeckia pubescens the seeds of Tricosanthes kirilowii, P. ailanthoides, and the stem of P. ginseng.

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.

The present study investigated the antitumor activity of the aqueous-alcoholic extracts from unripe cotton balls of Gossypium indicum. An Exposure of murine B16 melanoma and L1210 lymphoma cells to the extracts resulted in their severe deaths in time- and concentration-dependent manners. Of the extracts, hydrophilic fractions were most efficacious for the antitumor activity and found to contain certain amounts of catechin and its derivatives. The hydrophilic extract fraction C36B2-8 had approximately 10 times more cytotoxic effects on B12 and L1210 cells than on isolated murine thymocytes. High concentrations (>150 $\mu$g/ml) of C 36B3-8 mainly induced necrotic cell death. At low concentrations (<100 $\mu$g/ml), however, C 36B3-8 induced not only necrosis but also apoptosis of the two tumor cell lines, which was proved by the TUNEL staining and DNA fragmentation techniques. The data indicate that certain ingredients of the cotton ball extract of G. indicum have an antitumor activity.

Echinacea angustifolia의 부위별(꽃봉오리, 잎, 줄기 및 뿌리) 메탄을 추출물의 암세포(HepG2, 3LL, HL60, L1210)를 대상으로 한 항암 활성과 전자공여능을 검색한 결과는 다음과 같다. 1. 에키네시아 메탄을 추출물의 간암세포인 HepG2 cell 대한 MTT assay는 농도의존적으로 세포독성 효과가 증가하였으며, 인간유래 백혈암세포인 HL60 cell의 경우에 잎과 뿌리 추출물은 저농도에서부터 독성효과가 컸고, 줄기와 꽃봉오리는 저농도에서는 독성효과가 낮았으나 고농도로 갈수록 독성효과가 커짐을 알 수 있었다 폐암세포인 3LL cell과 마우스 유래 백혈암세포인 L1210 cell에 대한 경우는 세포독성효과가 없었다. 2. Hemacytometer에 의한 HepG2 cell의 암세포 성장에 미치는 효과는 배양기간이 증가함에 따라 농도의존적으로 증식억제 효과가 증가되었다. 3. HepG2 세포주의 형태학적 변화에서 대조군은 암세포가 조밀하게 중첩되어 증식되었으나 시료를 0.5 mg/mL 이상의 농도로 첨가하였을 때 세포의 결속력이 감소되어 세포주위가 흐트러지고 세포가 사멸된 것을 관찰 할 수가 있었다. 4. 전자공여능의 수준은 부위에 따라 최고의 EDA를 나타내는 농도가 달랐으며, 뿌리와 줄기부위는 저농도에서도 매우 높은 전자공여능을 나타내었다.

In an effort to increase of the antitumor activity of 2(S)-$2^{I}$,$5^{I}$-trihydroxy-7, 8-dimethoxyflavanone isolated from Scutellaria indica, we synthesized its analogues, II, III and IV. They showed potent cytotoxicity in vitro against cancer cell lines, L1210, K562 and A549. On the basis of $ED_50$ values against the cancer cell lines, III exhibited about 2-7 times stronger activity than I against various cell lines. We tested the antitumor activity of the analogues against Sarcoma 180 cells in vivo and evaluated the structure-activity relationship. The antitumor activity appeared to be related to the hydrogen bond between carbonyl group at C-4 and hydroxyl group at C-5, in contrast to cytotoxic action.
