title: Establishment of a HPLC method for preclinical pharmacokinetic study of the novel anti-Parkinson's disease candidate drug FLZ in rats.
abstract: An HPLC method was established and validated for the determination of compound FLZ, a synthetic novel anti-Parkinson's disease candidate drug, in rat plasma. FLZ and the internal standard bicyclol were extracted from plasma by solid-phase extraction method and analyzed on a Restek C18 column (4.6 x 250 mm, 5 microm) with a mobile phase consisting of methanol and water (60:40, v/v) at a flow rate of 1.0 mL/min. The detection wavelength was set at 320 nm. The calibration curve was linear within the concentration range from 25 to 500 ng/mL (r2 > 0.999), the limit of quantitation was 25 ng/mL and the average recovery was 92.0% with the RSD less than 5.9%. The relative standard deviation for intra- and inter-day precision was less than 3.8 and 6.9%, respectively. The established HPLC method was validated to be a simple, rapid and reliable procedure and applied to study the preclinical pharmacokinetics of FLZ in rat plasma, and it was the first time that the pharmacokinetics of FLZ had been investigated.
