Understanding ligand selectivity and efficacy at melatonin (MT 1 , MT 2 ) and serotonin (5-HT 2C ) receptors remains a key challenge in central nervous system (CNS) drug discovery. Ligands combining MT 1 /MT 2 agonism with 5-HT 2C antagonism are of therapeutic relevance in depression and circadian rhythm disorders. This review provides a comprehensive overview of ligands reported for these receptors in ChEMBL, with an emphasis on compounds evaluated across multiple targets.
