treatment option for various cancers, including lung cancer. In order to find compounds with superior bioactivity and less toxicity against lung cancer, novel spin-labeled 5-fluorouracil (5-FU) derivatives (3a–f) were synthesized and evaluated against four human tumor cell lines (A-549, DU-145, KB, and KBvin). Two promising compounds 3d and 3f exhibited IC50 values of 2.76 and 2.38 μM, respectively
化学疗法是各种癌症(包括肺癌)的一般治疗选择。为了找到对肺癌具有较高生物活性和较低毒性的化合物,合成了新型自旋标记的5-氟尿嘧啶(5-FU)衍生物(3a - f),并针对四种人类肿瘤细胞系(A-549,DU- 145,KB和KBvin)。两种有希望的化合物3d和3f对非小细胞肺癌细胞A-549的IC 50值分别为2.76和2.38μM。这些化合物的细胞毒性是5-FU的两倍,对其他测试细胞系的毒性也较小。化合物3f对A-549的选择性细胞毒性是5-FU的7倍。我们的结果表明,化合物3d和3f值得进一步研究,以发展成为非小细胞肺癌的临床试验候选药物。
