    摘要:

    目的 探讨东莨菪内酯在大鼠肝微粒体孵育体系中的代谢产物及其含药血清对大鼠肝星状细胞的 影响。 方法 应用高分辨液质联用技术对东莨菪内酯在大鼠肝微粒体孵育体系中的代谢产物进行分析,并观察其 含药血清对大鼠肝星状细胞的影响。 采用 ACQUITY UPLC HSS T3 色谱柱 (100 mm×2. 1 mm 内径 1. 8 μm) 和 0. 1%甲酸水溶液-0. 1%甲酸乙腈流动相进行梯度洗脱,通过高分辨的二级质谱分析东莨菪内酯的代谢产物。 制 备各组大鼠含药血清分别运用 Annexin V-APC 单染法和 MTT 法检测含药血清诱导大鼠 HSC 凋亡及抑制其增殖的 情况。 结果 通过大鼠肝微粒体孵育体系统初步鉴定了 3 个东莨菪内酯的代谢产物,提示其主要代谢途径为脱甲 基化和葡萄糖醛酸化反应。 含药血清有较弱的诱导大鼠 HSC 凋亡、抑制 HSC 增殖作用。 结论 结合先前的研究, 东莨菪内酯的抗肝纤维化作用不直接作用于 HSC,应结合其代谢产物情况,进一步进行其作用机制的深入研究,以 明确其作用靶点。

    Abstract:

    Objective To investigate the metabolites of scopoletin using a rat liver microsomal incubation system and the effects of drug-containing serum on rat hepatic stellate cells (HSC). Methods The metabolites of scopoletin from the rat liver microsomal incubation system were analyzed by high-performance liquid chromatography-mass spectrometry (HPLC-MS) and the effects of drug-containing serum on rat HSC were observed. The metabolites of scopoletin were analyzed by high-resolution second-order mass spectrometry with an ACQUITY UPLC HSS T3 column (100 mm×2. 1 mm i. d.d., 1. 8 μm) and 0. 1% formic acid aqueous solution-0. 1% formic acid acetonitrile mobile phase. Annexin V-APC single staining and MTT method were used to observe the induction of apoptosis and inhibition of proliferation of HSC induced by drug-containing serum. Results Three metabolites of scopolactone were identified with the rat liver microsome incubation system, which indicated that the main metabolic pathway was demethylation and glucuronidation. The drug-containing serum had a weak effect on inducing HSC apoptosis and inhibiting HSC proliferation. Conclusions Combined with previous studies, the anti-fibrotic effects of scopolactone do not directly affect HSC, and further study is needed to clarify the possible mechanism.
