BioAssay: AID 480270

Agonist activity at human GPR17 expressed in human 1321N1 cells assessed as induction of [35S]GTPgammaS binding after 30 mins by rapid filtration assay

The application of frontal affinity chromatography-mass spectrometry (FAC-MS), along with molecular modeling studies, to the screening of potential drug candidates toward the recently deorphanized G-protein-coupled receptor (GPCR) GPR17 is shown. GPR17 is dually activated by uracil nucleotides and cysteinyl-leukotrienes, and is expressed in organs typically undergoing ischemic damage (i.e., more ..

Description:
Title: Frontal affinity chromatography-mass spectrometry useful for characterization of new ligands for GPR17 receptor.

Abstract: The application of frontal affinity chromatography-mass spectrometry (FAC-MS), along with molecular modeling studies, to the screening of potential drug candidates toward the recently deorphanized G-protein-coupled receptor (GPCR) GPR17 is shown. GPR17 is dually activated by uracil nucleotides and cysteinyl-leukotrienes, and is expressed in organs typically undergoing ischemic damage (i.e., brain, heart and kidney), thus representing a new pharmacological target for acute and chronic neurodegeneration. GPR17 was entrapped on an immobilized artificial membrane (IAM), and this stationary phase was used to screen a library of nucleotide derivatives by FAC-MS to select high affinity ligands. The chromatographic results have been validated with a reference functional assay ([(35)S]GTPgammaS binding assay). The receptor nucleotide-binding site was studied by setting up a column where a mutated GPR17 receptor (Arg255Ile) has been immobilized. The chromatographic behavior of the tested nucleotide derivatives together with in silico studies have been used to gain insights into the structure requirement of GPR17 ligands.
