Schisandrin C, a dibenzocyclooctadiene lignan isolated from the fruits of Schisandra chinensis (Turcz.) Baill. (Schisandraceae), was investigated for cytotoxicity and influence on three human cancer cell lines. Among human hepatocelluar carcinoma cells (Bel-7402), human breast cancer cells (Bcap37) and human nasopharyngeal carcinoma cells (KB-3-1), Bel-7402 cells were most sensitive with IC50 equal to 81.58 ± 1.06 μ M after treatment with schisandrin C for 48 h. Cytotoxicity of schisandrin C on tumor cells depends on cellular accumulation of the drug. The intracellular schisandrin C concentration was assayed by high-performance liquid chromatography (HPLC) and showed that schisandrin C could permeate the cell membrane. Staining with Hoechst 33258 showed fragmentation and condensation of chromatin in the cell treated with 75 μ M schisandrin C for 24 h. Flow cytometric analysis was performed to determine hypodiploid cells. The results of flow cytometry indicated that the percentage of hypodiploid Bel-7402 cells was 40.61 ± 1.43% after 24 h treatment with 100 μ M schisandrin C. The treatment resulted in the appearance of a hypodiploid peak (sub-G0/G1 region), probably due to the presence of apoptosing cells and apoptotic bodies with DNA content less than 2n. To our knowledge, this is the first report against human hepatocelluar carcinoma cells (Bel-7402) of schisandrin C.

从五味子中分离的五味子C对人癌细胞系的活性

五味子 C,一种从五味子 (Turcz.) Baill 果实中分离的二苯并环辛二烯木脂素。(五味子科),研究了细胞毒性和对三种人类癌细胞系的影响。在人肝细胞癌细胞 (Bel-7402)、人乳腺癌细胞 (Bcap37) 和人鼻咽癌细胞 (KB-3-1) 中,Bel-7402 细胞最敏感,用五味子C 48小时。五味子 C 对肿瘤细胞的细胞毒性取决于药物的细胞积累。细胞内五味子 C 浓度通过高效液相色谱法 (HPLC) 测定,表明五味子 C 可以渗透细胞膜。用 Hoechst 33258 染色显示,在用 75 μ M 五味子 C 处理 24 小时的细胞中染色质发生断裂和凝聚。进行流式细胞术分析以确定亚二倍体细胞。流式细胞术结果表明,100 μ M五味子C处理24 h后亚二倍体Bel-7402细胞的百分比为40.61±1.43%。处理导致亚二倍体峰(sub-G0/G1区域)的出现,可能是由于存在DNA含量小于2n的凋亡细胞和凋亡小体。据我们所知,这是五味子 C 对人肝细胞癌细胞 (Bel-7402) 的首次报道。用 100 μ M 五味子 C 处理 24 小时后为 43%。处理导致出现亚二倍体峰(亚 G0/G1 区域),这可能是由于存在凋亡细胞和 DNA 含量小于 2n 的凋亡小体。据我们所知,这是五味子 C 对人肝细胞癌细胞 (Bel-7402) 的首次报道。用 100 μ M 五味子 C 处理 24 小时后为 43%。处理导致出现亚二倍体峰(亚 G0/G1 区域),这可能是由于存在凋亡细胞和 DNA 含量小于 2n 的凋亡小体。据我们所知,这是五味子 C 对人肝细胞癌细胞 (Bel-7402) 的首次报道。
