Salvicine,a novel topoisomerase Ⅱ inhibitor,exerts its potent anticancer activity by ROS generation

Acta Pharmacologica Sinica 2007年第9期28卷 1460-1465页

作者： Ling-hua MENG Jian DING division of antitumor pharmacology,State Key laboratory of Drug Research,shanghai institute of materia medica,Chinese Academy of Sciences,shanghai 201203.china division of antitumor pharmacology State Key laboratory of Drug Research Shanghai Institute of Materia Medica Chinese Academy of Sciences Shanghai China

Salvicine is a novel diterpenoid quinone compound obtained by structural modi-fication of a natural product lead isolated from a Chinese herb with potent growthinhibitory activity against a wide spectrum of human tumor cells in vitro and inmice bearing human tumor xenografts. Salvicine has also been found to have aprofound cytotoxic effect on multidrug-resisitant (MDR) cells. Moreover, Salvicinesignificantly reduced the lung metastatic foci of MDA-MB-435 orthotopicxenograft. Recent studies demonstrated that salvicine is a novel non-intercalativetopoisomerase II (Topo II) poison by binding to the ATPase domain, promotingDNA-Topo II binding and inhibiting Topo II-mediated DNA relegation and ATPhydrolysis. Further studies have indicated that salcivine-elicited ROS plays acentral role in salvicine-induced cellular response including Topo II inhibition,DNA damage, circumventing MDR and tumor cell adhesion inhibition.

Antihepatoma effect of alpha-fetoprotein antisense phosphorothioate oligodeoxyribonucleotides in vitro and in mice

World Journal of Gastroenterology 2001年第3期7卷 345-351页

作者： Xing Wang Wang~1 Jin Hui Yuan~1 Ru Gang Zhang~1 Li Xia Guo~1 Yong Xie~2 Hong Xie~1 ~1Department of Biotherapy,shanghai institute of Cell Biology,Chinese Academy of Sciences,shanghai 200031,china ~2Department of Biology,Hong Kong University of Science and Technology,chinaDr.Xing Wang Wang earned Ph.D.from shanghai institute of materia medical,Chinese Academy of Sciences in 1997.Now a professor at shanghai institute of Cell Biology,Chinese Academy of Sciences. Department of Biotherapy Shanghai Institute of Cell Biology Chinese Academy of Sciences 320 Yue-Yang Road Shanghai 200031 China.

AIM: To evaluate antihepatoma effect of antisense phosphorothioate oligodeoxyribonucleotides (S-ODNs) targeted to alpha-fetoprotein (AFP) genes in vitro and in nude mice. METHODS: AFP gene expression was examined by immunocytochemical method or enzyme-linked immunosorbent assay. Effect of S-ODNs on SMMC-7721 human hepatoma cell growth in vitro was determined using microculture tetrazolium assay. In vitro antitumor activities of S-ODNs were monitored by measuring tumor weight differences in treated and control mice bearing SMMC-7721 xenografts. Induction of cell apoptosis was evaluated by fluorescence-activated cell sorter (FACS) analysis. RESULTS: Antisense S-ODN treatment led to reduced AFP gene expression. Specific antisense S-ODNs, but not control S-ODNs, inhibited the growth of hepatoma cells in vitro. In vitro, only antisense S-ODNs exhibited obvious antitumor activities. FACS analysis revealed that the growth inhibition by antisense S-ODNs was associated with their cell apoptosis induction. CONCLUSION: Antisense S-ODNs targeted to AFP genes inhibit the growth of human hepatoma cells and solid hepatoma, which is related to their cell apoptosis induction.

＜正＞Curcumin（CUR） is a polyphenol derived from the plant Curcuma longa and displays potential anti-cancer *** of the mechanisms stems from its ability to induce cancer cell cycle arrest followed by suppression of cell proliferation.
