title: Determination of deramciclane and N-desmethylderamciclane in human plasma by liquid chromatography-tandem mass spectrometry using off-line robotic sample pretreatment.
abstract: A rapid and highly sensitive LC-MS-MS method using deuterium-labelled internal standards was developed and evaluated for the simultaneous determination of deramciclane and its pharmacologically active metabolite (N-desmethylderamciclane). The sample preparation based on liquid-liquid extraction was carried out with an off-line robotic system. Evaluation of this analytical method shows that samples can be assayed with acceptable accuracy and precision in the 0.1 to 50 ng/ml concentration range for both compounds. The method was applied for the quantitative determination of deramciclane and its metabolite in human plasma samples during a food interaction pharmacokinetic study.
