  • The anticancer activities of petroleum ether extract of Panax ginseng root(crude GX) and its partially purified fraction from silicic acid column chromatography (7:3 GX) were studied with Sarcoma 180(S-180) or Walker carcinosarcoma 256 (Walker 256) in vivo and with L1210 leukemic lympocyte in vitro. Potential cytotoxic activities of the crude GX and against L1210 cells were compared with those of 5-Fluorouracil (5-FU) and saponin derivatives (Panax-diol, Panax-triol, Diol saponin, Triol saponin) in vitro. In order to observe the physiological effects of the crude GX and 7:3 GX on the animals with cancer, hemoglobin(Hb), red blood cell(R.B.C) and white blood cell after treatment with each GX in comparison with corresponding control groups, respectively. The anticancer effects of the crude GX and 7:3 GX were estimated by measuring the survival time of S-180 bearing mice after treatment with them. The experimental results obtained are summarized as follows; 1. The one unit of cytotoxic activity against L1210 cells was equivalent to 2.54$\mu\textrm{g}$ and 0.88$\mu\textrm{g}$of the crude GX and 7:3 GX per ml of culture medium, respectively. 2. The cytotoxic activities of Panax-diol, Panax=triol, Diol saponin and triol saponin against L1210 cells were not detected. 3. The anticancer activities of 5-FU against L1210, S-180 and Walker 256 were very effective in vivo and vitro tests. 4. The significantly increased W.B.C values of mice after inoculation with S-180 cells were reduced to normal range by the crude GX treatment. 5. The significantly decreased Hb values of rats after inoculation with Walker 256 were recovered to normal range by oral administration of the crude GX. 6. The survival times of mice inoculated with S-180 cells were extended about 1.5 to 2 times by the 7:3 GX treatment compared with their control group.

  • In order to find out a proper connecting bridge between 5-fluorouracil(5-FU) and a macromolecule such as a polypeptide, potentially hydrolytic N$^{1}$-derivartives of 5-FU have been systhesized and evaluated for their biological activity. When tested with in vitro leukemic L$_{1210}$ cells all the obtained derivartives exhibited slightly higher antitumor activity than the parent 5FU. Among them the N$^{1}$ -carbamoyl analogue 2 and N$^{1}$-acetamido analogue 6b showed 50% inhibition of the L$_{1210}$ cell growth at the concentrations of 5.01$\times$10$^{-8}$M and 1.03$\times$10$^{-7}$M, respectively. When tested against sarcoma 180 tumor cells inoculated into mice, the compounds 2 and 6b exhibited, respectively, 62% and 54% inhibition of the solid tumor growth at the 5-time doses of 100 mg/kg/day. Both compounds, N$^{1}$-carbamoyl analogue 2 and N$^{1}$-acetamido analogue 6b, realeased the parent 5-FU when incubated in the L$_{1210}$ cell cultural media for 5 hrs.

  • Taklihwangki-Tang was a drug that treated carbuncle and cellulitis. So, the purpose of this Study was to investigate effect of Taklihwangki-Tang on the anti-cancer and proliferation of immunocytes, nitric oxide(NO) production of peritoneal macrophages. We used Taklihwangki-Tang extract(THT) with freeze-dried, 8wks-old male mice and cancer cell lines(L1210, S-180) for this Study. The proliferation of cells was tested using a colorimetric tetrazoliun assay(MTT assay). The results of this Study were obtained as follow ; THT was showed cytotoxicity on the L1210 and S-180 cell lines, increased proliferation of thymocytes. And the combined effects of THT and vincristine were became cytotoxicity of cancer cell lines and increased significantly proliferation of thymocytes. THT accelerated proliferation of thymocytes in normal mice, and decreased significantly proliferation of L1210 cells and accelerated significantly NO production of peritoneal macrophages in L1210 cells transplanted mice. This results suggest that THT inhibit proliferation of cancer cells by becoming immunocytes activity(NO production, proliferation of T-cell).

  • 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.

  • A strongly cytotoxic fraction (Fc-2, ED50=0.0003$\mu\textrm{g}$/ml) against L1210 cell was obtained from the root, seed and fruit of Trichosanthes kirilowii. Administration of Fc-2 prolonged the life span of the BDF1 mice bearing L1210 and the ICR mice bearing S-180 by 135%, and 130%, respectively. The Fc-2 affected L1210 cells were enlarged in their diameters two or three times in comparison with the untreated ones. When 20mg/kg of Fc-2 was administered, intraperitoneally, all the mice were killed.

  • The present study was undertaken to investigate the anticancer activity of monoterepenes in the animal and the cancer cell line tests. Both of the noncyclic and cyclic monoterpenes showed significant life prolonging effects on ICR mouse with abdominal cancer induced by Sarcoma 180 cells up to 67.4% and 63.5% in case of linalool and geraniol, respectively. Linalool and geraniol also exhibited very excellent cytotoxicity against L1210 leukemic cells with $IC_{50}$/ value of 0.32 $\mu\textrm{g}$/mι in 5 days culture condition. In the presence of linalool and geraniol, the generation of $O_2$$^{[-10]}$ ion were found to be increased proportionally to the cytotoxicity arisen from these monoterpenes. Furthermore, the antioxidant enzymes activities such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) responsible for the conversion of $O_2$$^{[-10]}$ ion to $H_2O$$_2$ and then to $H_2O$ augmented remarkably by linalool and geraniol. All data put together it can be postulated that monoterpenes may kill abdominal cancer cells of ICR mouse probably by activating anticancer system of the body, whereas the death of L1210 cells may be due to the detrimental attacks of reactive oxygen species (ROS) including $O_2$$^{[-10]}$ in spite of antioxidant enzymes activities to overcome the ROS attacks.
