Determination of key receptor-ligand interactions of dopaminergic arylpiperazines and the dopamine D2 receptor homology model
JOURNAL OF MOLECULAR MODELING, 19:1751-1762, APR 2013
Interest in structure-based G-protein-coupled receptor (GPCR) ligand discovery is huge, given that almost 30 % of all approved drugs belong to this category of active compounds. The GPCR family includes the dopamine receptor subtype D2 (D2DR), but unfortunately-as is true of most GPCRs-no experimental structures are available for these receptors. In this publication, we present the molecular model of D2DR based on the previously published crystal structure of the dopamine D3 receptor (D3DR). A molecular modeling study using homology modeling and docking simulation provided a rational explanation for the behavior of the arylpiperazine ligand. The observed binding modes and receptor-ligand interactions provided us with fresh clues about how to optimize selectivity for D2DR receptors.
