RESINIFERATOXIN Chemical Properties,Usage,Production

Description

Resiniferatoxin (57444-62-9) is an ultrapotent TRPV1 activator (Ki=43 pM).1 Resiniferatoxin is 100-10,000 fold more potent than capsaicin for most responses yet displays a spectrum of activity distinct from capsaicin.2 A potent sensory neuron excitotoxin.3 Induces a long lasting analgesia in a rodent model of burn pain.4 SEVERE IRRITANT – HANDLE WITH CARE

Chemical Properties

white to off-white solid

Uses

Resiniferatoxin has been used as an agonist to transient receptor potential vanilloid 2 (TRPV2):

for complex preparation for cryo-electron microscopy structural studies
to test its effect towards immune responses toP.aeruginosa in sensory neurons associated with the cornea
to study its effects in the denervation of the peripheral sensory nerves in psoriatic mice

Definition

ChEBI: Resiniferatoxin is a heteropentacyclic compound found in Euphorbia poissonii with molecular formula C37H40O9. It is an agonist of the transient receptor potential cation channel subfamily V member 1 (TrpV1). It has a role as a TRPV1 agonist, a plant metabolite, a neurotoxin and an analgesic. It is a diterpenoid, an ortho ester, a tertiary alpha-hydroxy ketone, a member of phenols, a monomethoxybenzene, an organic heteropentacyclic compound, a carboxylic ester and an enone.

Hazard

A poison.

Biological Activity

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

Biochem/physiol Actions

Resiniferatoxin (RTX) is an analog of capsaicin. It effectively ablates corneal sensory neurons by activating transient receptor potential vanilloid 1 (TRPV1) channels. RTX facilitates corneal bacterial clearance. It also elicits protective functionality towards cardiac function in a rat model with congestive heart failure (CHF).
