selective antitumor efficacy in the four colon cancer cell lines, with IC50 values ranging from 2.3 to 10.2 µM. Furthermore, QTZ05 inhibited colony formation in HCT-116 cells in a concentration-dependent manner. Cell cycle analysis data indicated that QTZ05 caused an arrest in the sub G1 cell cycle in HCT-116 cells. QTZ05 induced apoptosis in HCT-116 cells in a concentration-dependent manner that was
合成了一系列1 H-吡唑并[3,4- b ]喹啉-3-胺衍生物,并评估了十种癌细胞系(包括乳腺癌(MDAMB-231和MCF-7),结肠( HCT-116,HCT-15,HT-29和LOVO),前列腺(DU-145和PC3),脑(LN-229),卵巢(A2780)和人胚肾(HEK293)细胞(非癌细胞)线。在筛选的八种衍生物中,化合物QTZ05在四种结肠癌细胞系中具有最强效和选择性的抗肿瘤功效,IC 50值范围为2.3至10.2 µM。此外,QTZ05以浓度依赖的方式抑制HCT-116细胞中的集落形成。细胞周期分析数据表明,QTZ05导致HCT-116细胞亚G1细胞周期停滞。QTZ05以浓度依赖的方式诱导HCT-116细胞凋亡,其特征在于染色质浓缩和荧光素偶联膜联蛋白V的荧光增强。我们的研究结果表明QTZ05可能是化学疗法发展的有价值的原型靶向大肠癌细胞的凋亡途径。
