Previously, it was reported that 3[3‐(2,4‐dinitrophenylamino)‐propyl]‐5‐fluorouracil 8c unlike its components 5‐fluorouracil (5‐FU) 6 and 2,4‐dinitroaniline 2 in HT‐29 cells under aerobic conditions had no cytotoxicity but showed radiosensitizing activity. In this study several analogues of 8c differing in the number of linking methylene groups were prepared and tested for in vitro cytotoxicity and
以前,有报道称HT-29细胞中的3 [3-(2,4-二硝基苯氨基)-丙基] -5-氟尿嘧啶8c与它的成分5-氟尿嘧啶(5-FU)6和2,4-二硝基苯胺2不同。有氧条件没有细胞毒性,但表现出放射增敏活性。在这项研究中,制备了几种在连接亚甲基数量上不同的8c类似物,并测试了在有氧和低氧条件下的体外细胞毒性和放射增敏活性。通过5‐FU 6与多聚甲醛和2,4-二硝基苯胺2的反应在一个锅中制备栓系化合物8a在浓盐酸存在下,通过N-(溴代烷基)-2,4-二硝基苯胺5b-f与1-(叔丁氧羰基)-5-氟尿嘧啶7反应,然后水解制备化合物8b-f的保护基团。通过3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑(MTT)和碘化丙啶(PI)-洋地黄皂苷测定法和敏化增强比值(SER)来测定被测化合物的细胞毒性根据在不存在和存在每种敏化剂的情况下的放射存活曲线,分别测量37%的存活率,作为放射增敏活性的量
