Aim: A sensitive LC-MS/MS method was developed and validated for estimation of ZYAN1 in human blood/urine.
Methods: An analog internal standard IOX2 along with ZYAN1 was quantified using selective reaction monitoring in positive mode. The chromatographic separation was performed by gradient elution with C analytical column (3 µm, 50 mm × 2.0 mm) with 4-min run time using an acidified mobile phase consisting of ammonium formate and acetonitrile. Protein precipitation enabled extraction of analytes from diluted blood/urine.
Results: Calibration curve of ZYAN1 was linear (2-5000 ng/ml). The recovery of ZYAN1 and IOX2 was between 87 and 104%. Interday and intraday accuracy and precision was found well within the acceptance criteria.
Conclusion: The validated assay was applied for clinical pharmacokinetics of ZYAN1 in healthy volunteers.
