  • Praecoxin A, an ellagitannin, purified from Alnus hirsuta var.microphlla was evaluated on the antitumor activity. Praecoxin A had the significant cytotoxicity to s ix tumor cell lines: human chronic myelogenous leukemia K-562, human promyelocytic leukemia HL-60, mouse leukemia P388, mouse lymphocytic leukemia L-1210, sarcoma-l8O, mouse lymphoma L5178Y except L-1210. And the most sensitive cell line was K-562 ($ED_{50}=2.43{\mu}g/ml$). The $ED_{50} of praecoxin A against HL-60, P388, L-1210, sarcoma7l8O and L5178Y were 6.28, 8.66, 10.00, 7.01, $9.32{\mu}g/ml$, respectively. Praecoxin A showed the increasing effect in life span by 36.8% on the 1st day after treatment of 10mg/kg in mice bearing sarcoma-180 tumor cells (ascitic form) via NCI (National Cancer Institute, U.S.A.) protocol in vivo assay. As a result, praecoxin A is considered to show the antitumor activity.

  • Cancer chemoprevention refers to the use of natural or synthetic substances to prevent initiational and promotional events that occur during the process of carcinogenesis. Thesium Chinese Turczaninow aqua-acupuncture solution (TCTAS) and Astragli Radix aqua-acupuncture solution (ARAS) were tested as the cancer chemopreventive agents using biochemical markers of carcinogenesis. The effects on the inhibition of phorbol 12- myristate 13-acetate(TPA)-induced free radical formation in HL-60 cells and the inhibition of polyamine metabolism were measured. There is significant inhibition of TAP-induced free radical formation in human leukemic cells with cells with ARAS. Proliferation of Acanthamoeba castellanii was inhibited by TCTAS and ARAS. TCTAS and ARAS positive in these assays may inhibit the carcinogenesis process and is considered promising cancer-preventing agents.

  • The purpose of this research was to investigate the effects of Chungjokupye-tang(CJKPT) on the anti-carcinogenic action. The cell viability of mouse spienocytes and thymocytes were enhanced by the addition of CJKPT. CJKPT were increased of splenic and thymic T lymphocytes, such as T/sub H/ cells were markedly increased by the treatment of CJKPT in vivo. CJKPT treatment induced the apoptotic cell death of Jurkat and HL60 leukemia cells. CJKPT reduced mitochondrial transmembrane potential and increased the expression of ICE, c-myc and p53 gene in Molt-4cells dose dependant manner. These results suggest that CJKPT have an anti-carcinogenic action via immunoregulatory mechanism.

  • Antiproliferative activity of the ethanol extract of Atractylodes japonica rhizomes (AJEX) was investigated using methyl thiazolyl tetrazolium (MTT) assays with various cancer cell lines (HL-60, MCF-7, SK-Br-3, MDA-MB-453, HepG2, Hep3B, PC-3, LNCaP, MKN 28, MKN 45, and HT-29 cells). Gastric carcinoma cell lines were the most responsive in terms of cell proliferation. The $IC_{50}$ of MKN 28 and MKN 45 cells were 35.98 and 27.57 ${\mu}g/mL$, respectively. Moreover, gastric carcinoma cells exposed to AJEX underwent apoptosis, as determined by Annexin V binding assay. Compared to respective control level, exposure to the AJEX at each $IC_{50}$ concentration resulted in a remarkable increase in the shift of cell populations. Present results suggest that AJEX possess potential anticancer properties.
