Determination of thalidomide concentration in human plasma by liquid chromatography-tandem mass spectrometry

Abstract: A rapid, sensitive and specific analytical method based on high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed for the determination of thalidomide concentration in human plasma. The analyte and internal standard were extracted by liquid-liquid extraction with ether-dichloromethane (3:2, v/v) and separated on a TC-C18 column using methanol-10 mM ammonium acetate-formic acid (60:40:0.04, v/v/v) as the mobile phase at a flow rate of 0.9 ml/min. The detection was performe… Show more

“…Whether the phenotypes in zebrafish and chicken are a result of species-specific downstream pathways or the high dose (400 µM) and direct application of thalidomide to the limb buds ( Ito et al, 2010 ), which both could result in off-target effects, remains to be shown. The plasma concentration of thalidomide in humans is, however, unlikely to exceed 10 µM ( Bai et al, 2013 ; Dahut et al, 2009 ), a concentration that results in effective degradation of SALL4, but is 40 times below the dose found to be teratogenic in chicken and zebrafish embryos. While we do not observe degradation of mmSALL4 or drSALL4 upon high-dose exposure, we cannot rule out that such high doses will induce degradation of other ZnF targets in zebrafish or chicken, which could potentially result in the observed phenotypes.…”

“…Poucos métodos de LC-MS/MS validados foram reportados para a quantificação de talidomida em fluidos biológicos (Bai et al, 2013;Li et al, 2021;Roche et al, 2012;Shu et al, 2016;Teo et al, 2002) e apenas três métodos reportaram a quantificação de talidomida no plasma por LC-MS/MS, principalmente usando extração líquido-líquido, que pode apresentar algumas limitações, incluindo baixa recuperação e necessidade de maiores volume de solventes e maior quantidade de amostras (Kole et al, 2011). Além disso, nenhum dos métodos reportados empregou a técnica de UHPLC, nem uma abordagem alternativa de obtenção de amostra.…”

“…Alguns métodos LC-MS/MS são reportados para a quantificação de THD em fluidos biológicos, incluindo plasma, soro e sêmen, mas nenhum em DS (Bai et al, 2013;Li et al, 2021;Roche et al, 2012;Shu et al, 2016;Teo et al, 2002). Para a preparação da amostra 100 μL de WP e 200 μL de DPS foram necessários no presente método.…”
