Potent analog of capsaicin that is an agonist at vanilloid receptors (Ki = 43 pM). Like capsaicin, it acts as a selective modulator of primary afferent neurons. Also available as part of the Vanilloid TRPV1 Receptor Tocriset™.

Literature in this Area
Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
