Solvent and TLC-fractionations of the root of Salvia miltiorrhiza have yielded the results as follows ; Solvent fractions Petr. ether Ether Ethy1 acetate Water Control 100uL 0 0.2 35.1 41.9 43.0 50ul 0.7 3.7 37.2 42.0 TLC-fractionation and the Cytotoxic activity Fractions I II III IV V VI Petr. ehter Control 100uL13.0 7.1 16.8 1.2 30.9 23.2 0.5 48.3 50uL 37.1 26.1 30.0 20.1 45.7 27.2 29.7 Among the solvent fractions the petroleum ehter fraction corresponding to the concentration of 20ug/ml has showed the strongest Cytotoxic activity. (no cell survived) A double dilution of the fraction(10ug/ml) still showed strong activity.(0.2 cells survived) The ether fraction contained strong activity. Of the fraction which have veen obtained by a prcparative silicagel TLC I, II, III & IV were cytotoxic, but V and VI were inactive Howevcr, it is worthwhile to note that no one of these has no strong Cytotoxicity as the pertoleum ether fraction itself. This observation says that the active fractions could be additive or synergic to each other. The most active fraction, IV, was scrached out from the TLC and its UV-spectrum taken. The absorption maxima were 207 and 272 nm, indicating the presence of a flavanone strucuture.

This research was performed to screen the cytotoxic activities of some pharmaceutical insect relatives. Cytotoxic activities of total extract and fractions of hexane, ethyl acetate, methanol, water and boiling water were extracted from four pharmaceutical insect relatives: the Chinese gall, the cicada slough, the hornet nest and the batryticated silkworm. These extracts were investigated against the cancer cell lines of L1210, P388 and SNU-1 in vitro tests. Results showed that, ED, , against the cancer cell lines of L1210, P388 and SNU-1 were 0.55, 0.50, and $0.83{\mu}g/ml$ in the ethyl acetate fraction from the Chinese gall; 1.07, 2.19, and $2.24{\mu}g/ml$in the ethyl acetate fraction, 1.51, 1.26, and $1.45{\mu}g/ml$ in the water fraction and 1.48, 2.29, and $1.29{\mu}g/ml$in the boiling water fraction from the cicada slough; 3.31, 2.00, and $6.61\mug/ml$ in the water fraction from the hornet nest and 13.80, 19.95, and $31.62{\mu}g/ml$in the hexane fraction and 33.88, 21.88, and $25.12{\mu}g/ml$in the ethyl acetate fraction from the batryticated silkworm, respectively. All of the fractions mentioned above showed high cytotoxic activities and could be suggested for further studies in vivo tests.

A new series of highly water soluble platinum(II) complexes {Pt(II)[1,3-bis(phenylthio) propane](trans- -1,2-diaminocyclohexane) (PC-1) and Pt(II)[1,3-bis-(phenythio)propane] cis-1,2-diaminocyclohexane(PC-2)} were synthesized, and characterized by their elemental analysis and by various spectroscopic techniques[infrared(IR), 13C-nuclear magnetic resonance (NMR)]. In vitro antitumor activity of new Pt(II) complexes was tested against P-388 and L-1210 mouse lymphocytic leukemia cell lines, PC-14 / P, PC-14/ADM and PC-14 / CDDP human pulmonary adenocarcinima, DU-145 human prostate carcinoma, HT-1376 human bladder carcinoma, ZR-75-1 human breast carcinoma, MKN-45/P and MKN-45/CDDP human gastric adenocarcinoma cell lines using colorimetric MTT[3-(4,5-dimethyl thiazol-2-yl)-2.5-diphenyltetrazoliumbromide] assay for cell survival and proliferation. PC-1 showed active against L-1210, P-388 leukemia, human lung, stomach, prostate, bladder and breast cancer cell lines, and the antitumor activity of these compounds were comparable or superior to those of PC-2 and displatin. The nephrotoxicities of PC-1 and PC-2 were found quite less than that of cisplatin using MTT and [3H] thymidine uptake in rabbit proximal tubule cells and human kidney cortical cells. Based on these results, this novel platinum (II) complex compound (PC-1) represents a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low nephrotoxicity.

Flavin mononucleotide (1,4-butanediamine) Pt(II) complex (7FMN) was synthesized and screened anticancer activity [J. Pharm. Soc. Korea 43(6),762-770 (1999)]. 7FMN have good water solubility and moderate anticancer activiy In this paper cell-cycle specificity and nephrotoxicity were studied. Interaction of DNA with cisplatin and synthesized 7FMN was analyzed by flow cytometry and showed G2 arrest in L1210 cell line. It means that cell-cycle on L1210 was inhibit in S phase by cisplatin and 7FMN. In order to biochemically analyze nephrotoxicity of cisplatin and 7FMN, after injecting each agent intraperitoneally, blood was exsanguinated after 6 hours, 1 day, 3 days and 7 days, respectively. Then, serum was separated from the blood. The serum level of BUN, creatinine and uric acid in cisplatin and 7FMN administated mice (25~35 g, ICR strain, a dose each 8,12 and 16 times of the $IC_{50}$/ value, cisplatin; 7 times) were determined by autochemistry analyzer. In cisplatinadministered mice group, BUN level was elevated than normal control group at 3rd day and repaired at 7th day. In 7FMN administrated group was not elevated. Creatinine and uric acid level were no difference with the normal control group. Therefore synthesized 7FMN is less toxic than cisplatin in nephrotoxiciaty.

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.

2- or 6-Substituted BZT-N derivatives were synthesized, and their cytotoxic activity against can-cer L1210 and SNU-1 cells was examined. The antitumor action was also assessed in mice bearing S-180 cells in peritoneal cavity. In a comparison, it was found that 6-substituted BZT-N derivatives exhibited higher potencies in both bioactivities than 2-substituted BZT-N derivatives against L1210 cells in in vitro and S-180 in vitro tests exception of compound 36. Interestingly, it was observed that 2-substituted compound 36, which has methyl group at RI position, exhib-ited a better antitumor activity than 6-substituted compounds against L1210 and SNU-1 in vitro. The EDso value of 2-substituted compound 36 against L1210 was found to be comparable to the EDso value of adriamycin and was even better against the solid cancer cell line SNU-1. It was also observed that 2-substituted compound 36 showed better antitumor activity in mice bearing S-180 cells in the peritoneal cavity. The T/C (％) value of 2-substituted compound 36 was simi-lar to that of adriamycin. Quantitative structure-activity relationship (QSAR) tests reveal that the experimental E $D_{50}$ values against SNU-1 closely correlate with both the calculated HOMO ener-gies ( $E_{HOMO}$) and the measured H-NMR chemical shift of 3-H ($\delta$$_{H}$). The results suggests that a compound having higher $E_{HOMO}$ and $\delta$$_{H}$ values usually should have a lower E $D_{50}$ (SNU-1) value.lue.lue.lue.

In an effort to screen new selective antitumor agents from the broth of soil microorganism, cytotoxicity oriented screening was performed against tumor cells and 3 compounds (Compound 1, 2 and 3) were isolated from Sreptomyces parvullus ISP 5048 and their chemical structures were determined. Among these compounds, Compound 2 showed the highest cytotoxicity against P388Dl and L1210. While the $IC_{50}$/ values of compound 2 against P388Dl and L1210 were 0.073$\mu$g/ml and 0.07$\mu$g/ml, respectively, and the $IC_{50}$/ value of Compound 3 was 0.17$\mu$g/ml against human lung cancer cells, A549, the cytotoxicity of Compound 2 and 3 against normal cell line, Vero E6 cell was about 4- and 8-fold lower than that of adriamycin. Based on the chemical analysis data, Compound 3 was octacosamicine A, a known antibiotic, which was reported by Dobasih et al. (1988). Taken together the results demonstrated that Compound 2 and Compound 3 has the possibility to be developed as antitumor agent because of its potent cytotoxicity as well as high selectivity against various cancer cell lines.

Bioassay-guided fractionation of Crataegus pinnatifida (Rosaceae) gave two cytotoxic ursane-type triterpenes which were identified as uvaol (1) and ursolic acid (2) by physicochemical and spectroscopic methods. 3-Oxo-ursolic acid (3) was synthesized from ursolic acid (2) by Jones method. The cytotoxic activities of these compounds were tested against murine L1210 and human cancer cell lines (A549, SK-OV-3, SK-MEL-2, XF498, and HCT15) in vitro. Compounds 1 and 2 showed moderate cytotoxicities against L1210, whereas they showed weak activities against human cancer cell lines. However compound 3 exhibited potent cytotoxic activities both in murine and in human cancer cell lines.
