Metabolite Identification
Common NameCitalopram propionic acid
DescriptionCitalopram propionic acid belongs to the class of organic compounds known as isocoumarans. Isocoumarans are compounds containing the coumaran skeleton, which consists of a benzene ring fused to a 1,3-dihydrofuran ring. Citalopram is an antidepressant drug of the selective serotonin reuptake inhibitor (SSRI) class. It has U.S. Food and Drug Administration (FDA) approval to treat major depression, and is prescribed off-label for a number of anxiety conditions. Citalopram propionic acid is a metabolite of citalopram. Citalopram propionic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). citalopram propionic acid can be biosynthesized from citalopram aldehyde through its interaction with the enzyme aldehyde oxidase. In humans, citalopram propionic acid is involved in citalopram metabolism pathway.
