Potent, selective and competitive silent antagonist for the NOP opioid receptor. Binds to NOP with high affinity (pKi = 10.24) and displays > 3000-fold selectivity over δ, μ and κ opioid receptors. Antinociceptive and opposes the action of nociceptin in vivo.
(Modifications: Gly-1 = N-(Bn)Gly, Gln-17 = C-terminal amide)

Peptides Involved in Appetite Modulation Scientific Review
Written by Sonia Tucci, Lynsay Kobelis and Tim Kirkham, this review provides a synopsis of the increasing number of peptides that have been implicated in appetite regulation and energy homeostasis; putative roles of the major peptides are outlined and compounds available from Tocris are listed.
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.
