原始语种摘要: Abstract(#br)Pimavanserin is a new drug approved by the FDA for Parkinson's disease psychosis and other neurological disorders such as Alzheimer's disease. In this study, we developed a UPLC-MS/MS method to quantify pimavanserin disposition in the brain and its pharmacokinetics in mice. Vilazodone was used as the internal standard. Pimavanserin and IS were extracted by liquid-liquid extraction using tert -butyl methyl ether and separated using an Acquity UPLC BEH™ C 18 column. The mobile phase consisted of solvent A (0.1% formic acid in acetonitrile) and B (0.1% formic acid in 20 mM ammonium acetate buffer) (A: B, 70:30 v/v) at a flow rate of 0.25 ml/min. The multiple reaction monitoring transitions were performed at m / z 428.23 → 98.15 for pimavanserin and m / z 441.70 > 155.03 for the...
