  • 21plants, which collected from Korea and Japan, were applied to antitumor and cytotoxic screening tests against sarcoma 180 a ascitec in mice. The results are summariged as follows : 1) The total packed cell volume method has been used for the antimeoplastic screening for from natural higher plants in Korea. By this method, we have found out that Selaginella involves, Patrinia hispida, Archyranthes japonica and Solanum nigrum having significant activity and also Cydonia sinensis and Rubia akane showed slight activity to antitumor 2) The total packed cell volune method has been used for the antineoplastic screening for from natural higher plants in Japan.

  • SB31, an extract of Pulsatilla koreana, has been tried as an antitumor agent by traditional medicine pratitioner in Korea for the past 30 years, SB31 was evaluated for cytotoxic and antitumor activity against a variety of cancer cell lines. The SB31 exhibited 5-6 fold less cytotoxic activity against normal mononuclear cells (ED$\sub$50/. 1.1 mg/$m\ell$) than against cancer cell lines (ED$\sub$50/ 0.14-0.19mg/$m\ell$). (omitted)

  • Many attention has been focused on developing new chemotherapeutic agents for a treatment of cancer from natural products. From Carpesium divaricatum S. et Z. (Compositae), various monoterpenoid compounds were isolated and exhibited mild antitumor activity against human tumor cell lines. These facts prompted us to explore the structure-activity relationship of these compounds. The synthesis of monoterpenoid compound was accomplished by Fries rearrangement, Grignard reaction, elimination, allylic oxidation, esterification and epoxidation as key steps. The results of in vitro cytotoxicity (A549, SK-OV-3, SK-MEL-2, XF498, HCT15) of the synthesised compounds are as follows: First of all, epoxide moiety is prerequisite for cytotoxic activity in diester compound. Any kind of compounds with olefin or diol moiety instead of epoxide ring exhibited poor or mild cytotoxic activity respectively. Of o-acetoxy and isobutoxy epoxy esters, p-sub-stituted phenylacetate compounds exhibited high cytotoxic activities against SK-MEL-2 and HCT15.

  • Antitumor and anti-metastatic effects of mineral powder(MP) were studied. In the present study, MP did not exhibit the any cytotoxic activity against leukemic cells such as L1210 and U937 tumor cell lines in vitro. Also, MP did not exhibit the any cytotoxic activity against solid cells such as A549 and B16-BL6 tumor cell lines in vitro. However, in vivo, MP exhibit a significant antitumor activity in BDF1 mice bearing Lewis lung carcinoma cells(LLC) with inhibition rates of 46 and $23\%$ at 200 and 100 mg/kg/day, respectively. Furthermore, in pulmonary colonization assay, MP exhibit the inhibitory effect of tumor metastasis. From these results, it was concluded that MP had antitumor and anti-metastatic activity suggesting its application for the prevention and treatment of cancer.

  • 6-(1-azidoalkyl)-DMNQ derivatives compared to 2-(1-azidoalkyl)-DMNQ isomers, exhibited higher cytotoxic activity against L1210 mouse leukemia cells and stronger inhibition of DNA topoisomerase-I (TOPO-I), suggesting involvement of steric hindrance. However, similar antitumor activity against mice bearing S-180 cell was shown by 2-an 6-(1-azidoalkyl)-DMNQ derivatives.

  • Oncolytic vaccinia virus is an engineered vaccinia virus that selectively destroys cancer cells and induces tumor immune response. Oncolytic vaccinia expressing mouse GM-CSF showed cytotoxic activity against various kinds of cancer cells when oncolytic vaccinia virus expressing human GM-CSF and mouse GM-CSF is intravenously administered in the mouse CT26 colon tumor model. Cancer cells treated with isolated immunoglobulin G from the serum with complement showed these cytotoxic activity and complement observed dose-dependent cytotoxic effect. These results suggest that oncolytic vaccinia virus expressing mouse GM-CSF can increase oncolytic vaccinia virus by inducing anticancer antibody in a mouse tumor model. Further studies are needed on antitumor immunity of GM-CSF.

  • The polysaccharide fraction from the rhizome of Trichosanthes kirilowii (Cu-curbitaceae) showed marked antitumor and cytotoxic activity with immunopotentiating activity. It was evidenced by the increase in the number of circulating leucocytes and peritoneal exudate cells and the recovery of lowered antibody forming activity in mice. The polysaccharide was mainly composed of glucose, galactose, fructose, manmose and xylose and a small amount of protein.

  • We previously reported that the extract of unripe cotton ball of Gossypium indicum shows cytotoxic activity and induces an apoptosis in vitro. In present study, its antitumor activity was investigated in vivo. Butanol soluble extract of unripe cotton ball reduced the weight of solid tumor in sarcoma 180 transplanted mouse model. It showed stronger activity than that of Krestin.

  • Background and Objective : In order to investigate the effects of Gilgyunglwedok-tang (GRT) on antitumor activity and antimetastatic activity, studies were done experimentally. Materials and Methods : Experimental studies were perfonned for the cytotoxic effect on BALB/c mouse lung fibroblast cells, the proliferating effect of splenic lymphocyte, the expression of CD3e/CD4, CD3e/CD8, and B220 in peripheral blood mononuclear cells (PBMCs), the cytotoxic effect on A549, SK-OV-3, SK-MEL-2, MCF-7 cells, the inhibitory effect on the activity of DNA topoisomerase I, the T/C% in ICR mice bearing S-180, the inhibitory effect of Cell adhesive of A549 Cells and SK-OY-3 Cells to complex extracellular matrix, the inhibitory effect on lung colonies, the change of lung tissue, the antiangiogenic activity, and the effect on MMP-2 and MMP-9 gene expression in the RT1080 cell line. Results and Conclusion : The results were obtained as follows : 1. In the cytotoxic effect on BALB/C mouse lung fibroblast Cell, GHT didn't show the significant cytotoxic effect on BALB/C mouse lung fibroblast cell compared to the control group. 2. In thymidine uptake assay, GHT showed the significant proliferating effect of splenic lymphocyte in proportion to the concentration. 3. In the expression of CD3e/CD4, CD3e/CD8, and B220 in peripheral blood mononuclea cells (PBMCs) of mice, GRT had no significant change to the normal group in CD4. However, GRT showed an increase to the normal group in CD8 and GHT in the only $1\mu\textrm{g}/ml$ category showed an increase to the normal group in B220. 4. In the cytotoxic effect of GRT on A549, SK-OY-3, SK-MEL-2 and MCF-7 cells, there was no significant cytotoxic effect compared to the control group. 5. In the inhibitory effect on the activity of DNA topoisomerase I, GHT in the $10\mu\textrm{g}/ml$ category showed the inhibitory effect on the activity of DNA topoisomerase I in proportion to the concentration. 6. In the T/C% in ICRmice bearing S-180, GHTtreated group showed 123.7% of T/C% compared to the control group. 7. In the inhibitory effect of cell adhesive of A549 Cells and SK-OV-3 Cells to complex extracellular matrix, GRT in the only $100\mu\textrm{g}/ml$ category showed the significant inhibitory effect compared to the control group. 8. In the inhibitory effect on lung colonies, GHT showed the significant inhibitory effect on lung colonies compared to the control group. 9. In the change of lung tissue, GHT showed a significant decrease of lung cancer growth, interalveolar fibrosis and hyaline material compared to the control group. In the development of lymphocyte around lung cancer cells and lung parenchymal, GHT showed the significant inducement efficacy compared to the control group. 10. In CAM assay, the antiangiogenic activity of GHT showed 30%. 11. In the effect on MMP-2 and MMP-9 gene expression in the RT1080 cell line, GHT had no significant inhibitory effect on MMP-2 and MMP-9 gene expression compared to the control group. According to the above results, it could be suggested that GHT has an antitumor activity and antimetastatic activity.

  • Many types of compounds have been isolated from higher plants till now, that is, alkaloids, terpenes, lignans, steroids and so on. One of them, named as RA series Cyclic hexapeptides isolated from Rubia akane and R. cordijofia also have strong antineoplastic activity against various types of tumors. Till now 10 kinds ofRA series compounds were isolated and named as RA - I, II, III, IV, V, VI, VII, VIII, IX and X. Moreover,monogl-ucoside of RA - V newly Isolated from same plant. Many kinds of derivatives including natural RAcompounds were tested for QSAR, and one of them, RA - VII was screened up as a most suitable substance asan antitumor agent. RA - VII(=RA-700) has strong cytotoxic activity against KB cells, P388 Iymphocyticleukemia and MM2 mammary carcinoma cells. RA - VII has been under investigation for Phase I clinical trials.
