to the formation of new pyrazoline derivatives 8a-8u. All final compounds were characterized by spectral and elemental analyses. They were screened for their antiproliferative activities against A549 (lung), HepG-2 (liver), CaCo-2 (intestinal) and MCF-7 (breast) cancer cell lines. Some of the synthesized compounds exhibited promising antiproliferative activities especially compound 8k with IC50 values
在碱性条件下,将查尔酮3a - 3u与3-肼基-6-苯基哒嗪7环合导致形成新的吡唑啉衍生物8a-8u。所有最终化合物均通过光谱和元素分析进行表征。筛选了它们对A549(肺),HepG-2(肝),CaCo-2(肠)和MCF-7(乳腺癌)癌细胞系的抗增殖活性。某些合成的化合物显示出有希望的抗增殖活性,尤其是具有IC 50的化合物8k分别针对HepG-2,MCF-7和CaCo-2癌细胞系的8.33、1.67和10μM的最高值。此外,它们的抗增殖活性是由于细胞凋亡而不是坏死诱导,除了化合物8h表现出相同的凋亡和坏死特性。化合物8k显示caspase-3活性增加了5倍,表明细胞凋亡通过caspase-3活化而进行。
