The P2Y(1) receptor (P2Y(1)R) is a G protein-coupled receptor naturally activated by extracellular ADP. Its stimulation is an essential requirement of ADP-induced platelet aggregation, thus making antagonists highly sought compounds for the development of antithrombotic agents. Here, through a virtual screening campaign based on a pharmacophoric representation of the common characteristics of known P2Y(1)R ligands and the putative shape and size of the receptor binding pocket, we have identified novel antagonist hits of mu M affinity derived from a N,N'-bis-arylurea chemotype. Unlike the vast majority of known P2Y(1)R antagonists, these drug-like compounds do not have a nucleotidic scaffold or highly negatively charged phosphate groups. Hence, our compounds may provide a direction for the development of receptor probes with altered physicochemical properties. Published by Elsevier Ltd.
