In this study, 4',7-diacetoxyapigenin [4-(7-acetoxy-5-hydroxy-4-oxo-4H-chromen-2-yl) phenyl acetate] was synthesized for the first time. Its chemical structure was identified by UV, ESI-MS, (1)H and (13)C-NMR. It could inhibit the proliferation of Hep G2 cells in a dose-dependent manner and induce the significant increase of the G0/G1 cell population. After treatment by 4',7-diacetoxyapigenin, phosphatidylserine of Hep G2 cells could significantly translocate to the surface of the membrane. The increase of an early apoptotic population was observed by both annexin-FITC and PI staining. It was concluded that 4',7-diacetoxyapigenin not only induced cells to enter into apoptosis, but also affected the progress of the cell cycle.
在本研究中,首次合成了4',7-二乙酰氧基芹菜素[4-(7-乙酰氧基-5-羟基-4-氧代-4H-色烯-2-基)苯基乙酸酯]。通过紫外光谱、电喷雾电离质谱、氢核磁共振和碳-13核磁共振对其化学结构进行了鉴定。它能以剂量依赖的方式抑制肝癌细胞系Hep G2细胞的增殖,并诱导G0/G1期细胞数量显著增加。用4',7-二乙酰氧基芹菜素处理后,Hep G2细胞的磷脂酰丝氨酸可显著转移至细胞膜表面。通过膜联蛋白-FITC和碘化丙啶染色均观察到早期凋亡细胞数量增加。得出的结论是,4',7-二乙酰氧基芹菜素不仅能诱导细胞进入凋亡,还能影响细胞周期进程。
