摘要
从金丝马尾连提取的总生物碱及其主要成分碱甲(hernandezine)对P388白血病小鼠、腹水型S180及C26结肠癌小鼠有一定的治疗作用。在体外,碱甲明显地抑制小鼠白血病L1210细胞及人口腔癌KB细胞的生长,对小鼠正常造血祖细胞(CFU-GM)的抑制作用较弱。初步结果表明,碱甲可阻断G_1细胞向S期过渡,其杀细胞作用似为细胞周期特异性。金丝马尾连的其它两个成分碱乙(thalidezine)及碱丙(isothalidezine)也有类似的抑制癌细胞作用。
The total alkaloids of T. glandulosissimum and its main component hernandezine were found to be effective for treatment of mice bearing P388 leukemia, S180 ascites and C26 colon cancer. Although hernandezine inhibited the growth of mouse L1210 cells and human oral cancer KB cells in vitro markedly, its inhibitory effect on normal hemopoietic progenitor cells (CFU-GM) in mice was relatively low. Preliminary results showed that hernandezine blocked cell-cycle transfer from G1 to S phase, and its cytocidal action might be cell cycle specific. In addition, two other components, thalidezine and isothalidezine, isolated from the same plant exerted similar inhibitory effect on L1210 cells.
