New Rochelle, September 11, 2018-A novel high throughput screening (HTS) assay compatible with an ion channel biosensor component was used successfully to identify selective and active small molecule modulators of G protein-coupled receptor 119 (GPR119), a promising target for the treatment of type 2 diabetes and related metabolic disorders. The development of this cell-based HTS assay and its miniaturization are described in an article published in ASSAY and Drug Development Technologies, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Patricia McDonald, Ainhoa Nieto, Virneliz Fernandez-Vega and colleagues from The Scripps Research Institute, Jupiter, FL coauthored the article entitled "Identification of Novel, Structurally Diverse, Small Molecule Modulators of GPR119."
The researchers describe the use of a HEK293 cell line to co-express the receptor of interest and the ion channel, which functions as a biosensor for cAMP. The group presented data indicating having met their goal, with more than 500,000 small molecules screened and 200 modulators of hGPR119 identified for further follow-up. They were also able to miniaturize the assay and implement it in a 1536-well plate format.
"Prof. McDonald and her team have developed an efficient and robust assay platform to identify new hits for the treatment of type 2 diabetes. The congruence of GPCR screening and development of new drugs for diabetes and other metabolic diseases is of high interest to our readers," says ASSAY and Drug Development Technologies Editor-in-Chief Bruce Melancon, PhD, Director of the Chemical Synthesis and Drug Discovery facility at the University of Notre Dame.
