摘要: 目的:观察半边旗提取物5F 对SPCA-1 细胞的抑瘤作用及对细胞周期、DNA 、RNA 合成的影响。方法:用MTT 法观察5F 对SPCA-1 细胞的抑瘤作用;流式细胞术分析细胞周期变化;[3H]-TdR 和[3H]-UTR 掺入法观察5F 对SPC-A-1 细胞DNA 、RNA 合成的影响。结果:5F 对SPCA-1 细胞有显著抑制生长作用;在一定剂量5F 作用下SPCA-1 细胞表现为G1 期明显减少, 而G2 和S 期相对增多;5F作用24 h 后细胞[3H]-TdR 和[3H]-UTR 掺入量明显减少。结论:半边旗提取物5F 具有体外抗肿瘤活性;干扰肿瘤细胞的周期;对肿瘤细胞DNA 、RNA 合成有抑制作用。

Abstract: AIM: To study the effects of compound 5F, one of the diterpenoids extracted from Pteris Semipinnata L, on cell cycle and synthesis of DNA and RNA of SPC-A-1 cells.METHODS: Cytotoxicity was determined by MTT test, the cell cycle was analysed by flowcytometry (FCM) and the synthesis of DNA and RNA was observed by the [3H]-TdR and [3H]-UTP incorporation.RESULTS: Compound 5F strongly inhibited the growth of SPC-A-1cells, FCM analysis revealed that 5F could increase the percentage of cells in G2 and S phase and decrease those in G1 phase after 24 h treatment.The assays of [3H]-TdR and [3H]-UTP incorporation into DNA and RNA respectively showed obvious inhibition dose-dependent after exposure to 5F for 24 h.CONCLUSION: Compound 5F obviously inhibits SPC-A-1cells proliferation, arrests SPC-A-1cells in G2 and S phase and inhibits the synthesis of DNA and RNA.

Key words: Pteris Semipinnata L, diterpenoid, SPCA-1, cellcycle, DNA synthesis
