concentrated hydrochloric acid and to evaluate their cytotoxicity to Hep-G2 cells in terms of their active functional groups and polarity. The chemical structures of the PDs were characterized by Fourier transform infrared, nuclear magnetic resonance and high resolution mass spectroscopy. Two PDs (PD1 and PD2) were fractionated by silica gel column chromatography with a R f of 0.37 and 0.19, respectively
摘要 通过用浓盐酸对小白菊内酯进行化学修饰合成了两种小白菊内酯衍生物(PDs),并从活性官能团和极性方面评估了它们对Hep-G2细胞的细胞毒性。PDs的化学结构通过傅里叶变换红外、核磁共振和高分辨率质谱进行表征。两种 PD(PD1 和 PD2)在 1:1 (v/v) 己烷:乙酸乙酯流动相中通过硅胶柱色谱分离,R f 分别为 0.37 和 0.19,表明 PD1 的极性低于 PD2 . 与母体小白菊内酯相比,PD1 和 PD2 都失去了活性碳碳双键和环氧化物官能团,但保留了活性 14-甲基和 α-亚甲基-γ-丁内酯基团。尽管 PD1 和 PD2 具有相似的官能团,但它们的结构排列和极性不同。PD1 和 PD2 对 Hep-G2 细胞系的体外 IC 50 分别为 41.0 和 94.0 μg/ml,弱于小白菊内酯(PD1 > 小白菊内酯与其对 Hep-G2 细胞系的细胞毒性呈负相关) (parthenolide
