1H-1,2,3-triazole tethered isatin conjugates have been synthesized and evaluated for cytotoxicity on four human cancer cell lines. The results revealed 5a, 5c, 5e and 5n proved to be twice as potent as 5-fluorouracil on THP-1 cell line with 5a and 5c being most active exhibiting IC50 values of <1 against all cell lines except Caco-2. Activity profiles showed dependence on the substituents on isatin
已经合成了1 H -1,2,3-三唑拴系的靛红共轭物,并评估了其对四种人类癌细胞系的细胞毒性。结果表明5a,5c,5e和5n在THP-1细胞系上的效力是5-氟尿嘧啶的两倍,其中5a和5c最活跃,对除Caco-2以外的所有细胞系的IC 50值均<1。活性曲线显示出对异丁环的取代基的依赖性,优选氢,而任一环上的强吸电子氟和硝基取代基均降低了抗癌活性。
