A series of novel ferrocene-pyrazole derivatives containing nitric oxide donors as COX-2 inhibitors for cancer therapy were designed, synthesized and biologically evaluated. Among them, compound 7l displayed the most potent inhibitory against COX-2 (IC50 = 0.82 μM) and antiproliferative activities against Hela cells (IC50 = 0.34 μM) compared with Celecoxib (IC50 = 0.38 and 7.91 μM). The further mechanistic
设计,合成和生物学评估了一系列新的含一氧化氮供体作为COX-2抑制剂的二茂铁-吡唑衍生物。其中,化合物7升对COX-2(IC显示的最有效的抑制50 = 0.82μM)和针对Hela细胞的抗增殖活性(IC 50 = 0.34μM)塞来昔布进行比较(IC 50 = 0.38和7.91μM)。进一步的机理研究表明,7l可以通过线粒体去极化诱导Hela细胞凋亡,而7l的抗增殖活性与Hela细胞内细胞内NO释放水平呈正相关。最值得注意的是7公升可以显着抑制异种移植Hela细胞肿瘤模型中的肿瘤生长。总之,化合物7l可能是用于癌症治疗的有希望的候选物。
