(-)-pentazocine   

GtoPdb Ligand ID: 1606

Synonyms: pentazocine | WIN-20228
(-)-pentazocine is an approved drug (FDA (1967))
Compound class: Synthetic organic
Comment: (-)-pentazocine is one of the two enantiomers in the approved drug pentazocine. (-)-pentazocine is a κ-opioid receptor agonist, while (+)-pentazocine exhibits ten-fold greater affinity for the σ receptor. Pentazocine is a mixed agonist-antagonist opioid pain medication. It is postulated that pentazocine behaves as an agonist at the κ and σ opioid receptors and has weak antagonistic action at the μ receptor.
