Pharmacokinetics Laboratory

About the PK Lab

  • The Center for Drug Design (CDD) Pharmacokinetics (PK) lab aims to facilitate medicinal chemists' efforts to discover new lead candidates with proper drug-like properties, and to obtain research funding and publish academic research findings.

  • The PK lab is supported by the CDD and was initially established to provide ADME/PK support within the center. In the last five years, the lab has studied the preclinical ADME/PK of more than 300 compounds from various CDD drug discovery projects, and has contributed to the application of two awarded R01 NIH grants and the publication of 16 joint manuscripts.


  • The PK lab is equipped with a state-of-the-art LC-MS instrument (Agilent 1260 HPLC and AB Sciex QTrap 5500 MS) that is used to detect and quantitate small molecules in biological matrices.

  • The PK lab also manages an Agilent 6230B Time of Flight LC/MS system with capability of high resolution mass.

  • The PK lab has licensed Phoenix WinNonlin software for PK data analysis and modeling.
