The current investigation was carried out to find out the anticancer activity of the methanol extract from Buplerum falcatum against cancered ICR mouse and cancer cell lines such as J774A.1 and L1210 cells. Extract of Buplerum falcatum displayed the considerable augmentation(134%) of the survival of ICR mouse bearing Sarcoma 180 cancer. In addition, the cytotoxic effects of methanol extract of Buplerum falcatum against J774A.1 cells and L1210 cells were found to show $IC_{50}$ values of $57.3\;{\mu}g/ml$ and $54.6\;{\mu}g/ml$, respectively. In contrast to such cytotoxicity against cancer cells, the extract exerted only meagre toxicity against normal lymphocytes. The increased generation of $O_2^-$ and the considerably increased activities of super-oxide dismutase(SOD) and glutathione peroxidase(GPx) of both J774A.1 cells and L1210 cells in the presence of Buplerum falcatum extract implied that the observed cytotoxicities may have resulted from the detrimental effect of reactive oxygen species(ROS) evoked by Buplerum falcatum extract on the cancer cells.

To clarifiy the activating effects of Buthus martensi Karsch(BMK) on tumor promotion in two-stage carcinogenesis in mice was investigated. In vivo system, BMK was seen to gave an inhibitory activity on TPA-induced mouse ear edema. In addition, the BMK was proved to have antitumor-promoting activity in two-stage mouse skin carcinogenesis induced by DMBA and two-stage mouse lung carcinogenesis induced by 4-NQO as a initiator plus TPA and glycerol as a promoter. Moreover, BMK significantly exhibited an cytolytic effect in HepG2 cells and showed significant antitumor activity against Sarcoma-180 bearing mice by oral administration. These results suggest that BMK could be effective in adjuvant chemotherapy for human cancer.

The first original inducer of interferon had been synthesized in Russia in 1965-1967. It was 2-car-boxiethyl-germanysesquioxan (Lx-13) and other-1 hydroxigermanytrans-monohydral (Lx-5), These compounds have very high induct$\circledcirc$on of interferon. The strain of Panax ginseng C. A. Meyer was recultivated on medium with different concentiation of (Lx-13) and (Lx-5) many times. The strain was stabilized when biomass of cells contain of the Ge form 10${\times}$10-3mg% to 2.3x10-3mg% to ashes, Biomass are hard physical work (swimming test) and also had stress-protective, immunomodulating action and anticarcinogenic effect hampered the sarcoma-180 by 33-80% and suppressed quantity of metanes on 43-46%.

Water-soluble pectins isolated from Trichosanthes Rhizoma and Taraxii Herba and their deproteinized polysaccharides were purified through DEAE cellulose column and were applied to immunopotentiating and antitumor studies to clarify the nature of their activities of our previous reports. As the results of works, the lectins and deproteinized polysaccharides increased the number of circulating leukocytes and total peritoneal cells. And they markedly elevated the lowered production of antibody and reactivity of T Iymphocyte in tumor-bearing mice, which were rapidly recovered by discontinuance of sample treatments. They also decreased the growth of Sarcoma 180 solid tumor in mice.

The in vivo anti-tumor activities of decursinol angelate (1) and decursin (2) isolated from the roots of Angelica gigas were investigated. These two compounds, when administered consecutively for 9 days at 50 and 100 mg/kg i.p. in mice, caused a significant increase in the life span and a significant decrease in the tumor weight and volume of mice inoculated with Sarcoma-180 tumor cells. These results suggest that decursinol angelate (1) and decursin (2) from A. gigas have anti-tumor activities.

In the previous study we described the antitumor activity of GLB, a protein-polysaccharide fraction of the growing tips of Ganoderma lucidum, against sarcoma 180 solid tu mor in ICR mice. In this study we investigated the stimulatory activity of GLB on macrophages. When analyzed using a flow cytometer, GLB ($100{\mu}g/ml$) was found to increase the phagocytic activity of the BALB/c mouse peritoneal macrophages as well as chicken macrophage BM2CL cells against FITC-labeled C.albicans by 55.2% and 21.2%, respectively. GLB also increased the spreading and the expression of MHC class II molecules of BM2CL cells as well as the mouse peritoneal macrophages. From these results, it is clear that GLB is a strong stimulator to the macrophages.

To data, many types of compounds having antineoplastic activity have been isolated from higher plants, that is, alkalodids, terpenes, lignans, steroids and so on. Some of ther were isolated from Indonesian plants, Curcuma xanthorrhiza and Eurycoma longifolia. Bisaborane type compounds were compounds were isolated as antimeoplastic compounds againest Sarcoma 180A from C. xanthorrhiza, and quassinoids and euryrene type triterpenes from triterpenes from El longifolia. Casearines, a kind of diterpene, had been isolated as cytotxic components from Casearia sylvestris distributed in South America. RA series Cyclic hexapeptides isolated from Rubia akane and R. cordifolia also have strong antineoplastic activity against various types of tumors. Till now, 16 kinds of RA series compounds were isolated and named as RA-I~XVI. Moreover, monoglucoside of RA-V newly isolated from same plant. Many kinds of derivatives including natural RA compounds were tested for QSAR, and one of them, RA-VII was screened up as a most suitable substance as an antitumor agent. RA-VII(=RA 700) has strong cytotoxic activity against KB cells, P388 lymphocytic leukemia and MM2 mammary carcinoma cells. In some solution, three conformers of RA-VII were observed by NMR. It was discussed the relationship between conformation and activity. Total synthesis was already completed, but there is left room for improvement. Phase I clinical trials for RA-VII has been finished, then Phase II trials will be started before long.
