摘要: 将4种稳定氮氧自由基引入5-氟尿嘧啶,合成了10个新的5-氟尿嘧啶(Fu)自旋标记衍生物2a-8.经元素分析、IR、UV、MS和ESR确定了其组成和结构.化合物对KB、HCT-8和A 2780细胞毒性实验结果表明,化合物2a和3a的抗癌活性高于5-Fu,与HCFU的活性相当.

关键词: 5-氟尿嘧啶, 自旋标记, 氮氧自由基, 抗肿瘤活性

Abstract: Ten new spin-labeled derivatives of 5-fluorouracil(2a-8) were synthesized by introducing four kinds of stable nitroxyl radicals into N1 and N3 site of 5-Fu. The structures of these new compounds were confirmed by IR, UV, MS, ESR spectra and elemental analysis. The antitumor activities of these compounds were tested to be against KB, HCT-8 and A 2780. The preliminary results showed that the antitumor activities of compounds 2a and 3a were stronger than that of 5-Fu and were similar to that of HCFU.

Key words: 5-Fluorouracil, Spin-label, Nitroxyl radical, Antitumor activity
