A series of (o- and p-nitrobenzyloxycarbonyl)-5-fluorouracil derivatives were synthesized by reacting o- or p-nitrobenzyl chloroformate with 5-fluorouracil in the presence of triethylamine in DMF or Me2SO. The reductive activation of these agents was hypothesized to generate a reactive methide and 5-fluorouracil, two components that are capable of synergistic interaction through complementary inhibition
在三乙胺的存在下,在DMF或Me2SO中,使氯甲酸邻-或对硝基苄基酯与5-氟尿嘧啶反应,合成了一系列(邻-和对硝基苄氧基羰基)-5-氟尿嘧啶衍生物。假设这些试剂的还原活化产生反应性甲基化物和5-氟尿嘧啶,这两种成分能够通过互补抑制产生协同相互作用。在缺氧和需氧条件下,用这些试剂处理的EMT6肿瘤细胞的存活分数的测量可导致相等的细胞杀伤力,而与氧合作用的状态无关。一种合成的药物3-(对硝基苄氧基羰基)-5-氟尿嘧啶(4)在延长带有P388白血病和肉瘤180腹膜内植入物的小鼠的存活时间方面似乎优于5-氟尿嘧啶。
