The Small Molecule Screening Facility (SMSF) fosters collaborative drug discovery research between chemists, biologists and physician scientists that leads to the identification of new small molecules that inhibit disease targets and phenotypes in biochemical and cellular models relevant to any therapeutic area.


Our drug discovery services include:

News and Accomplishments


The SMSF migrated to a new scheduling system called iLab as of Monday, Oct. 19, 2015. If you did not receive an email with detailed instructions for activating your account in iLab and how to reserve equipment, please go to to register.


If you have questions or problems with this new system, please contact Gene Ananiev or Michael Hoffmann. All appointments for equipment usage or project discussions with SMSF staff should be made on iLab. 


Scott Wildman, PhD has recently joined the Small Molecule Screening Facility.  Scott is a computational chemist with expertise in drug design, molecular modeling, virtual screening and HTS hit triage. He will be collaborating with investigators from across campus to identify and optimize the design of small molecules and peptides that interact with targets of therapeutic and biological interest. Scott comes to UW from Washington University in St. Louis where he was a Research Assistant Professor in the Department of Biochemistry and Molecular Biophysics, and the Scientific Director of both the High-throughput Screening Core and Peptide Synthesis Core.  Prior to that, he worked at Pfizer for 7 years on a wide variety of drug targets, moving two molecules into clinical trials. He has a PhD in Medicinal Chemistry from the University of Michigan.


Tip-less, acoustic liquid dispensing of aqueous and DMSO solutions in 2.5nanoliter(!) and up volumes into 96, 384 and 1536-well plates is now available for any application on an Echo 555.

SMSF is the home of a new Seahorse Bioscience XFe96 Extracellular Flux Analyzer which simultaneously interrogates mitochondrial respiration and glycolysis - in a microplate, in real-time. The XFe96 Analyzer determines in vitro oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) in order to assess cellular functions such as oxidative phosphorylation, glycolysis and fatty acid oxidation.

With pilot project funding from Institute for Clinical and Translational Research (ICTR), the UW Carbone Cancer Center (UWCCC) and use of the UW Center for High-throughput computing, we have expanded our virtual screening capabilities to two million compounds on one binding pocket in one run and queries of over 100 protein binding pockets for compound binding.
