Press Release Body = Dr. Dominique Perrin, Group Leader of Biochemical Pharmacology
at Merck Serono International in Switzerland will give a presentation entitled
"Phosphatases Inhibitors: from Screening to Biological Activities" at GTCbio's 2nd
Assay Development & High Throughput Screening Conference on May 31-June 1 in Boston,
MA.

Protein tyrosine phosphatases (PTPs) play key roles in regulating tyrosine
phosphorylation levels in cells. Since the discovery of PTP1B as a major drug target
for diabetes and obesity, PTPs have emerged as a new and promising class of
signaling targets for drug development in a variety of therapeutic areas.
Phosphatase screening in-house was based either on generic substrate
6,8-difluoro-4-methyumbelliferyl phosphate (DiFMUP) using fluorescence intensity
readout or on specific phosphopeptides using an off-chip mobility shift assay.
Whilst assay robustness and sensitivity were comparable for both assays, the
mobility shift assay required a longer development time due to identification and
synthesis of a specific peptide and its cost per data point was higher. However
whilst most scaffolds found with DiFMUP assay were confirmed in the mobility shift
format, this latter assay allowed the identification of novel, more drug-like
chemical scaffolds.
Outcomes of screening campaigns as well as biological activities of positives will
be presented.

GTCbio's 2nd Assay Development & High Throughput Screening Conference on May 31-June
1 will take place at the Omni Parker House in downtown Boston, MA. The meeting will
be held concurrently with GTCbio's 2nd Protein Kinases in Drug Discovery Conference.
