title: Quantitative determination of L-775,606, a selective 5-hydroxytryptamine 1D agonist, in rat plasma using automated sample preparation and detection by liquid chromatography-tandem mass spectrometry.
abstract: L-775,606 is under investigation as a selective 5-hydroxytryptamine 1D agonist for the treatment of migraine. A reliable and sensitive method for the analysis of L-775,606 in plasma was required in order to support preclinical evaluation of this compound. A semi-automated sample preparation method using the Beckman Biomek 2000 workstation to perform all liquid handling tasks has been established. The sample analysis was performed using HPLC-MS-MS with a cycle time of 3.5 min per sample. Intra- and inter-day assay accuracy and precision are excellent with a calibration range of 1-2000 ng/ml and a reproducible limit of quantification of 1 ng/ml.
