  5-氟尿苷核脂衍生物的合成及其对人 HT-29 结肠癌细胞的细胞抑制/细胞毒活性

  摘要：

  化学治疗剂的主要缺点之一是由于高疏水性，它们不能充分穿透细胞膜。因此，我们合成了一系列选定的 5-氟尿苷 (5-FUrd; 2a) 核脂衍生物，在 N(3) 和/或 2',3'-O-位（即 3a- 7a 和 3c)，并使用 HT-29 人结肠癌细胞测试它们的细胞抑制/细胞毒性活性，与例如 5-FU (1) 和 5-FUrd (2a) 进行比较。在与荧光染料 Atto 425 缀合后进行被测物质的掺入和细胞内定位。我们发现所有 5'-O 标记的 Atto 425 衍生物都被人类 HT-29 细胞掺入并积累在其细胞质中。此外，在 HT-29 人结肠癌细胞处理 24 小时后，1 或 2a (10, 20, 40, 或 80 μM）显示与（阴性）对照相比，存活率显着降低（分别为 14-23 或 33-45%）。有趣的是，衍生物 3a 和 3c（40 和 80 μM）导致显着（77-95 或 89-96%，分别）抑制人

  An object of the present invention is to provide a method for accurately and quantitatively discriminating and detecting a wide variety of gene mutations, or particularly, single base substitutions or point mutations. In an ASP for analyzing gene mutations, or particularly, single base substitutions or point mutations, when a non-nucleotide component is added to the 5' end of at least one of the ASP and a primer paired therewith before amplification by PCR and amplification products thereof are separated by ion-exchange chromatography, even the amplification products having the same length can be separated and detected.

  本发明的目的是提供一种方法，用于准确和定量地鉴别和检测各种基因突变，特别是单碱基替换或点突变。在用于分析基因突变，特别是单碱基置换或点突变的 ASP 中，如果在 PCR 扩增前在至少一种 ASP 的 5'端和与之配对的引物中加入非核苷酸成分，并用离子交换色谱法分离其扩增产物，即使是具有相同长度的扩增产物也能被分离和检测出来。
