To evaluate the capability of human-induced pluripotent stem cell-derived hepatocytes (h-iPS-HEP) in drug metabolism, the profiles of the metabolites of fentanyl, a powerful synthetic opioid, and acetylfentanyl, an N-acetyl analog of fentanyl, in the cells were determined and analyzed. Commercially available h-iPS-HEP were incubated with fentanyl or acetylfentanyl for 24 or 48 h. After enzymatic hydrolysis, the medium was deproteinized with acetonitrile, then analyzed by LC/MS. Desphenethylated metabolites and some hydroxylated metabolites, including 4′-hydroxy-fentanyl and β-hydroxy-fentanyl, were detected as metabolites of fentanyl and acetylfentanyl in the medium. The main metabolite of fentanyl with h-iPS-HEP was the desphenethylated metabolite, which was in agreement with in vivo results. These results suggest that h-iPS-HEP may be useful as a tool for investigating drug metabolism.
为了评估人诱导多能干细胞衍生的肝细胞(h-iPS-HEP)在药物代谢中的能力,测定并分析了强效合成阿片类药物芬太尼和其N-乙酰化类似物乙酰芬太尼在细胞中的代谢物谱。将市售的h-iPS-HEP与芬太尼或乙酰芬太尼共同孵育24或48小时。通过酶解后,用乙腈去蛋白化处理介质,然后通过LC/MS进行分析。在介质中检测到去苯乙基代谢物和一些羟基化代谢物,包括4′-羟基芬太尼和β-羟基芬太尼,它们作为芬太尼和乙酰芬太尼的代谢物存在。与体内结果一致的是,h-iPS-HEP主要代谢芬太尼为去苯乙基代谢物。这些结果表明,h-iPS-HEP可能作为研究药物代谢的有用工具。
