respectively. Good biocompatibility with tumor cells can be observed in cell imaging. The anti-tumor mechanism of the compound was further studied by flow cytometry. After BP-2, BP-3 and BP-4 treated HeLa cells, the percentage of apoptotic cells was 19.07%, 22.09% and 27.3%, respectively. The cell cycle study found that, compared with the positive control 5-FU (48.05%), the compounds BP-2, BP-3 and BP-4
BODIPY-嘧啶(BP)是一种高选择性、高活性、高生物相容性的荧光药物,其特点是自身具有与荧光团结合的活性。将具有良好生物活性的嘧啶与荧光团结合,获得兼具抗肿瘤活性和荧光靶向探针功能的新型化合物是本研究的重点。在生物活性方面,研究了化合物对四种人类癌细胞(HepG2、HeLa、A-459 和 HCT-116)和人类正常细胞系 L-02 的体外细胞毒性。BP-4具有良好的抗增殖活性,其 IC 50值分别为 19.12 ± 2.29、13.47 ± 3.80、18.59 ± 7.42、14.57 ± 2.44 和 92.48 ± 6.03 μM。在细胞成像中可以观察到与肿瘤细胞的良好生物相容性。通过流式细胞术进一步研究了该化合物的抗肿瘤机制。后BP-2 ,BP-3和BP-4处理的HeLa细胞,凋亡细胞的百分比分别为19.07%,22.09%和27.3%。细胞周期研究发现,与阳性对照5-FU(48
