for obtaining a series of 5-arylidene derivatives 3–10, 13–18. Alternatively 11, 12 and their 5-arylidene derivatives were synthesized by means of 3-phenyl-5-aryl-1-thiocarbamoyl-2-pyrazoline as S,N-binucleophile via [2 + 3]-cyclocondensation approach. The structures of compounds were determined by 1H, 13C NMR, LC–MS, EI-MS and X-ray analysis. The in vitro anticancer activity of synthesized compounds
为了检查抗癌活性,获得了几种含有5-芳基-3-苯基-4,5-二氢-1 H-吡唑-1-基骨架的新型基于噻唑酮的化合物。5-芳基-3-苯基-4,5-二氢吡唑与4-硫代-2--2-噻唑烷酮或2-乙氧基甲硫基-2-噻唑啉-4-酮的反应生成起始4-(1和2)或2-取代(11和12),其中使用了Knoevenagel缩合获得一系列5-亚芳基衍生物的噻唑酮3 - 10,13 - 18。可替代地11,12并通过[2 + 3]-环缩合反应,以3-苯基-5-芳基-1-硫代氨基甲酰基-2-吡唑啉为S,N-双亲核试剂合成了它们的5-亚芳基衍生物。化合物的结构通过1 H,13 C NMR,LC-MS,EI-MS和X射线分析确定。在体外合成的化合物的抗癌活性是由国家癌症研究所测试,其中大部分显示在白血病,黑色素瘤,肺癌,结肠癌,中枢神经系统癌,卵巢癌,肾癌,前列腺癌和乳腺癌细胞系中的抗癌活性。讨论了结构与活性之间的关
