GtoPdb Ligand ID: 10455

Synonyms: EL-737 | Optaflexx® | Paylean® | ractopamin | Tomax®
Compound class: Synthetic organic
Comment: Ractopamine exhibits agonist activity at the trace amine receptor 1 (TA1) [4] and β-adrenoceptors [1,3].

In some countries ractopamine is used as a feed additive in commercial livestock husbandry to increase lean meat mass. This use is banned in the EU and many other countries, but is permitted in countries including the US, Canada, Mexico, Japan and South Korea. Ractopamine's effect on human physiology has not been fully characterised, so the safety of consuming trace ractopamine in meat from treated animals remains controversial.

Commercially used ractopamine is administered as the hydrochloride salt and is a racemic mixture of all 4 possible stereoenantiomers. We show the structure without specified stereochemistry to represent the mixture.
