Bioanalytical method development and validation of MES207, a neuropeptide FF receptor antagonist, and its application in preclinical pharmacokinetics.

ABSTRACT: The nonpeptide small molecule, MES207, exhibits 17-fold preferential binding to the neuropeptide FF receptor 1 (NPFFR1) over NPFFR2 and shows antagonist functionality at NPFF receptors. In order to further the development of MES207 as a NPFFR1 probe, an UPLC-MS/MS bioanalytical method was developed and validated to quantify MES207 in rat plasma for a linearity range of 3-200 ng/mL. The method was applied in the analysis of the plasma, brain, and urine samples collected during pharmacokinetic studies in healthy male and female Sprague Dawley rats. The animals were dosed through oral gavage (50 mg/kg) and intravenously (2.5 mg/kg). Test samples were analyzed using the validated bioanalytical method to generate plasma concentration-time profiles. The results were further subjected to non-comp
