3,5-Diamino-4-(3-trifluoromethylphenyldiazenyl)-1H-pyrazole was used as a starting scaffold for the synthesis of new pyrazole-based heterocycles to study their effects on the proliferation of three human cancer cell lines; human liver carcinoma cell line (HepG-2), colon cancer cell line (HCT-116) and human breast cancer cell line (MCF-7) using MTT assay. The synthesized compounds were characterized
3,5-二氨基-4-(3-三氟甲基苯基二氮烯基)-1 H-吡唑被用作合成新型吡唑基杂环的起始支架,以研究其对三种人类癌细胞系增殖的影响。使用MTT分析法检测人肝癌细胞系(HepG-2),结肠癌细胞系(HCT-116)和人乳腺癌细胞系(MCF-7)。根据IR,1 H NMR,13表征合成的化合物13 C NMR,质谱数据和元素分析结果。细胞毒性测定结果表明,某些化合物对所有测试的细胞系均显示出有效的生长抑制作用,IC50值在0.64–7.73μg/ mL范围内。乳腺癌细胞被用于进一步的详细研究,以了解最有效化合物的细胞生长抑制和细胞凋亡诱导作用的机制。结果表明,化合物3a,10b和11aMCF-7细胞在细胞周期的G2 / M期停滞,并可能通过caspase-3依赖性途径诱导凋亡。最活跃的化合物对caspase 3活性位点的分子建模和结合模式分析进一步为它们的促凋亡作用提供了协同机制。为了探索
