Approved drug PDB Ligand
escitalopram is an approved drug (FDA (2002))
Compound class: Synthetic organic
Comment: Escitalopram is a selective serotonin-reuptake inhibitor (SSRI) drug. It is the S-enantiomer of citalopram.
Marketed formulations may contain escitalopram oxalate (PubChem CID 146571). An X-ray structure of SERT bound by escitalopram ((S)-citalopram) reveals two binding sites for the drug: one central site, and one allosteric site [1]. When (S)-citalopram binds the allosteric site, it prevents unbinding of ligand at the central site, thereby preventing further ligand transport.
