Chemical Name: (E)-N-[(4-Hydroxy-3-methoxyphenyl)methyl]-8-methyl-6-nonenamide

Biological Activity

Prototypic vanilloid receptor agonist (pEC50 values are 7.97 and 7.10 at rat and human VR1 receptors respectively). Excites a subset of primary afferent sensory neurons, with subsequent antinociceptive and anti-inflammatory effects. Reversibly inhibits aggregation of platelets. Also available as part of the Vanilloid TRPV1 Receptor Tocriset™.

Technical Data

Soluble to 50 mM in DMSO and to 50 mM in ethanol
>98 %
Store at RT
