In this study, two series of 3-oxo-3H-benzo[f]chromene-2-carboxylic acid derivatives (compounds 5a–i and 6a–g) were synthesized. Their in vitro proliferation inhibitory activities against the A549 and NCI-H460 human non-small cell lung cancer (NSCLC) cell lines were evaluated. Their photophysical properties were measured. Among these target compounds, 5e exhibited the strongest antiproliferative activity by inducing apoptosis, arresting cell cycle, and elevating intracellular reactive oxygen species (ROS) level, suggesting that it may be a potent antitumor agent. In addition, compound 6g with very low cytotoxicity, demonstrated excellent fluorescence properties, which could be used as an effective fluorescence probe for biological imaging.
在本研究中,合成了两系列3-氧-3H-苯并[f]香豆烯-2-羧酸衍生物(化合物5a–i和6a–g)。评估了它们对A549和NCI-H460人类非小细胞肺癌(NSCLC)细胞系的体外增殖抑制活性。测量了它们的光物理特性。在这些目标化合物中,5e表现出最强的抗增殖活性,通过诱导细胞凋亡、 arrest 细胞周期和提高细胞内活性氧(ROS)水平,表明它可能是一种有效的抗肿瘤药物。此外,6g化合物具有非常低的细胞毒性,展现出优良的荧光特性,可作为生物成像的有效荧光探针。
