A series of novel N-arylpyrazole derivatives (4a–4l) bearing the sulfonamide moiety were synthesized by the condensation reaction of 1,3-dicarbonyl compounds with 4-hydrazinylbenzenesulfonamide. The structures of the obtained compounds were established on the basis of elemental (C, H, and N) and spectral analysis (1H NMR, 13C NMR, ESIMS, and FT-IR). These compounds were tested for their in vitro cytotoxic
通过1,3-二羰基化合物与4-肼基苯磺酰胺的缩合反应,合成了一系列带有磺酰胺基团的新型N-芳基吡唑衍生物(4a-4l)。根据元素(碳,氢和氮)和光谱分析(1 H NMR,13 C NMR,ESIMS和FT-IR)建立所得化合物的结构。测试了这些化合物对三种人类肿瘤细胞系MCF-7,Hela和A549的体外细胞毒性活性。结果表明,大多数获得的化合物对IC 50值较低的被测细胞系均显示出有希望的细胞毒性。吡唑衍生物4k最有效的一种是在苯环的3位和4位带有两个甲氧基的化合物。它对MCF-7细胞的细胞生长抑制作用优于塞来昔布和顺铂。
