Interactions between neuropsychiatric drugs with key residues in the orthosteric ligand binding pocket of GPCRs (e.g., adrenoceptors, dopamine receptors, histamine receptors, melatonin receptors, S1P1/5 receptors, and serotonin receptor). The small molecules regulate GPCR activity by stabilizing receptors at unique conformational state
