  • DA-125, a new anthracycline derivative, shows significant anticancer activities. We conducted a study to examine the local irritating effect of DA-125 using mice and rabbits. In the skin test in mice, intradermal injection of 0.4 mg of DA-125, compared to a dosage of 0.2 mg of adriamycin, had weak irritating potentials to induce skin ulceration and erythematous induration. A dosage of 0.6 mg of DA-125 produced similar degree of lesions in perivascular irritation model to that of 0.2 mg of adriamycin, but the healing time was shorter in the case of mice treated with DA-125. In ocular irritation study in rabbit, the highest M.O.I.(mean ocular irritation index) of 0.5% DA-125 solution was 0.67, therefore DA-125 could be considered as a practically non-irritating anticancer agent. These results suggest that substitution of DA-125 for Adriamycin would reduces the possibility of outbreaks of local irritation and the severity of the lesions.

  • In order to indentify the effect of Astragali Radix(A.R) on cyclophosphamide(C.Y) induced leukopenia, A.R. extracts(EAR) were treated to mice orally, and blood sampling was done by periods. For the in vivo experiments, mice were divided into 4 groups, which treated EAR before, or after C.Y injection, or both, or none. Rapid normalization in the peripheral blood count of WBC, neutrophils, lymphocytes, RBC, and platelets observed in every EAR treated group regardless of the treatment periods of EAR. These studies suggest that, A.R. premedication can be effective in protection of bone marrow suppression during anticancer therapy.

  • The purification of the MeOH extracts from the aerial parts of Aceriphyllum rossii Engler (Saxifragaceae) using column chromatography furnished fourteen compounds (1 - 14). The chemical structures of the isolated compounds were determined using mainly nuclear magnetic resonance spectra and mass spectrometry. All the isolated compounds were tested for their cytotoxic activity against LH-60, MCF-7 and HeLa cancer cells in vitro using a MTT assay method. Compounds possessing an olean-triterpenoid skeleton entirely exhibit dose dependent cytotoxic activity. These findings partially confirmed the anticancer effect of this medicinal plant, suggesting a further study on the anticancer potential of the triterpenoid structure in compounds from this plant.

  • A study was performed to compare the anticancer effects of Korean and Chinese red ginseng roots. The whole crude extracts or chloroform, methanol and acetone fractions of the crude extracts were added in the culture medium of three cancer cell lines, a mouse leukemia cell line ($P_{388}$), a human colon carcinoma cell line (HT-29) and a human rectal carcinoma cell line (HRT-18), to screen the growth inhibition effects. The results are summarized as follows : 1. Crude extracts of both Korean and Chinese red ginseng roots inhibited the proliferation of all the three cancer cell lines tested in a dose dependent manner. However, the growth inhibition effects of Korean red ginseng extracts were significantly greater than that of Chinese red ginseng. 2. An acetone fraction showed the greatest antiproliferative effects among the 11'hole crude extracts, chloroform, methanol and acetone fractions of the crude extracts. 3. These results suggest that the active antiproliferative components of the crude extracts are present mostly in the acetone fraction.

  • Ginseng is a natural product best known for its curative properties in diverse physiological processes such as cancer, neurodegenerative disorders, hypertension, and maintenance of hemostasis in the immune system. In previous decades, there have been some promising studies into the pharmacology and chemistry of ginseng components and the relationship between their structure and function. The emerging use of modified ginseng and development of new compounds from ginseng for clinical studies have been topics of study for many researchers. The present review deals with the anticancer, anti-inflammatory, antioxidant, and chemopreventive effects, and recent advances in microRNA technology related to red ginseng. The review also summarizes the current knowledge on the effect of ginsenosides in the treatment of cancer.

  • Present anticancer drugs in the clinical side have not showed a conclusive effect of the chemotherapy for cancer patients. In order to find much more efficient antitumor agents fromnatural resources, various screening methods vivo and in vitro have been developed by manyresearchers. The intention of this paper is to provide an outline of some background on the tumorsystem in drug development of natural products, to review some screening programs for theevaluation of antitumor activity and to introduce the practical procedures of some antitumorscreening methods in vivo and in vitro. At the end of this paper, the current literatures related toantitumor natural products from higher plants at our laboratory are described.Key words'anticancer drugs, screening methods.

  • Mylabris phalerata(MP) is an insect that has been used for the treatment of cancer in oriental medicine. To evaluate the anticancer activity of Mylabris phalerata, We measured the cytotoxicity of Mylabris phalerata solvent fractions such as MC, EA, BuOH and residual layers on U937, human monocytic leukemia cells. Of those fractions BuOH layer of Mylabris phalerata was the most effective with ID$_{50}$ of 140$\mu\textrm{g}$/ml. It effectively caused DNA fragmentation from the concentration of 50$\mu\textrm{g}$/ml, showed apoptotic nucleus by tenets assay and expressed apototic portion stained by Annexin-V. It also induced the activation of caspase-3 and cleavage of the substrate poly (ADP-ribose) polymerase (PARP). These results suggest BuOH layer of Mylabris phalerata exerts anticancer activity by induction of apoptosis via activation of caspase-3 protease.e.

  • Ecklonia cava is a brown alga(Laminariaceae) that is abundant in the subtidal regions of Jeju island in Korea. Phlorotannins were identified to be responsible for the biological activities in Ecklonia species. In the present study, triphlorethol-A, a phlorotannin, was isolated from Ecklonia cava and its anticancer properties were investigated. Triphlorethol-A was investigated whether it may show cytotoxicity effects against U937, HeLa, NCI-H460 and MCF-7 cancer cells by MTT test. As a result, triphlorethol-A did not show cytotoxic effects against tested four cell lines.

  • This study was Performed to determine the effects of antimutagenicity and anticancer of Taxus cuspidata produced in Korea. Extracts of Taxus cuspidata were obtained from leaves, barks and roots. All the samples tested had no effects on the mutagenicity by Ames test using Salmonella typhimurium TA98 and TA100 or rec-assay using Bacillus subtilis Hl7 and M45 strains. However the treatment of 50$\mu\textrm{g}$/plate of Taxus cuspidata extracts showed strong antimutagenicity with 98% inhibition against TA100 induced by MNNG and with 98% inhibition against TA98 and TA100 induced by 4NQO whereas 73~89% and 16~60% antimutagenic effect were shown against both strain induced by Trp-P-1 and $Benzo(\alpha)pyrene,$ respectively. The treatment of $0.5$\mu\textrm{g}$/{\mu}\ell$ root extracts had the highest cytotoxicity with 90% against liver cancer cell, Hep 3B, followed by bark extracts(87%) and leave extracts(72%), whereas $0.5$\mu\textrm{g}$/{\mu}\ell$ treatment of Taxus cuspidata extract had only 22~36% cytotoxicity on human normal liver cell WRL 68.
