In this study, a series of novel 2H-imidazo [1, 2-c] pyrazolo [3, 4-e] pyrimidine derivatives were designed, synthesized, and evaluated for their cytotoxic activities. The in vitro cell growth inhibition assay of the target compounds indicated their selectivity in inhibiting the proliferation of blood tumor cells (K562, U937) and solid tumor cells (HCT116, HT-29). Compound 9b exhibited the highest
在这项研究中,设计、合成了一系列新型 2H-咪唑并 [1, 2-c] 吡唑并 [3, 4-e] 嘧啶衍生物,并评估了它们的细胞毒活性。在体外目标化合物的细胞生长抑制测定表明在抑制血液的肿瘤细胞(K562,U937)和固体肿瘤细胞(HCT116,HT-29)的增殖它们的选择性。化合物9b对 K562 (IC 50 = 5.597 µM) 和 U937 (IC 50 = 3.512 µM)表现出最高的抗增殖活性。基于流式细胞术分析,化合物9b在S期引起细胞凋亡和细胞停滞的明显诱导。此外,蛋白质印迹分析显示化合物9b上调Bax的表达,下调Bcl-2的水平,并进一步激活K562细胞中的caspase-3。因此,化合物9b可能是一种值得进一步研究的潜在抗癌剂。
