一种基于荧光探针和HK-2细胞的中药肾毒性物质筛查方法及其应用

本研究采用荧光探针FDA标记HK-2细胞,创建了一种快速筛查肾毒性物质方法.方法学考察结果表明,所建的肾毒性体外评价模型线性度、稳定性和准确性均满足应用要求.将其用于《中国药典》收载的32种有毒中药的352个组分进行规模化普筛,发现巴豆等14种中药材的31个组分对HK-2细胞具有明显毒性,可能会引起肾毒性.其他18种中药的各组分对HK-2细胞未见明显毒性.

An approach to screen nephrotoxic components in traditional Chinese medicine based on fluorescent probe and HK-2 cells and its application

Using fluorescein diacetate labeled HK-2 cells, a fast method for screening nephrotoxic components in traditional Chinese medicines (TCMs) was proposed in this study. The methodology validation showed that the linearity, stability and accuracy of the proposed method were suitable for screening nephrotoxic components in vitro . This method was further applied on screen 352 components from 32 Chinese Pharmacopoeia-indexed toxic TCMs. The results indicated that 31 components from 14 toxic TCMs, including Badou, had significant toxicity on HK-2 cells, which suggested these components may cause nephrotoxicity. The components from the other 18 toxic TCMs had no significant toxicity on HK-2 cells.
