Mission

 

The Pharmacokinetics and Mass Spectrometry (PKMS) Core aims to facilitate researchers' efforts to discover new medicines, obtain research funding, file patent applications, and publish academic research findings.  

 

About the Core

The pharmacokinetics and mass spectrometry (PKMS) core plays a pivotal role in advancing the drug discovery, clinical translation, and optimization of novel and existing therapeutics. The PKMS core has a thirteen year track record of supporting: (1) quantitative LC-MS analysis of molecules and mass spectrometry imaging of spatial localization biomarkers in tissue section; (2) preclinical ADME and pharmacokinetics for lead compound optimization in drug discovery and development; (3) clinical pharmacokinetics and dosage regimen design for clinical trials.  

The PKMS core was founded in 2009 and has been funded by the cancer center supported grant (CCSG) since 2012. The PKMS core is led by Co-Directors Drs. Duxin Sun and Amit Pai. Dr. Sun has expertise in preclinical ADME, pharmacokinetics, and drug discovery. Dr. Pai has expertise in clinical pharmacokinetics and clinical trial design. Assistant director Dr. Bo Wen oversees the day-to-day operations that are run by ten full time staff members (four PhD and two MS level analytical chemists, two animal specialists, and two clinical study coordinators). PKMS core has eight LC-MS instruments that include three MS with high resolution MS capability and two MS with mass spectrometry imaging capability. 

In the core's short history, we have supported LC-MS analysis, pre-clinical ADME and PK of more than 6500 compounds; supported clinical pharmacokinetics of more than 55 compounds in clinical trials. We have contributed to more than 310 grant applications, in which 101 grants were funded with a total funding of $260 million to the University of Michigan. We have provided services to more than 70 U-M labs, and 20 external labs. Our work has resulted in over 130 joint manuscripts, with five patents issued and six pending. 

We can work with you either by joining your grant proposals as collaborators, for which we provide consultation as well as PK services, or fee-for-service via recharge. Please contact the PK Core assistant director, Dr. Bo Wen, if you are interested in working with us. 

The PK Core is supported by the College of Pharmacy, the Comprehensive Cancer Center, and the Center for Discovery of New Medicines.
