Chemical Taxonomy
Description belongs to the class of organic compounds known as rhamnofolane and daphnane diterpenoids. These are diterpenoids with a structure based on one the rhamnofolane or daphnane skeleton. The rhamnofolane and daphnane skeletons are closely related, being formally derived from casbane by two cyclizations (6,10 and 5,14) followed by cleavage of the 1,15 (daphnane) or 2,15 (rhamnofolane) cyclopropane bonds.

Toxicity Profile
Route of ExposureOral (ingestion) (2) ; dermal (2)
Mechanism of ToxicityResiniferatoxin activates the vanilloid receptor in a subpopulation of primary afferent sensory neurons involved in nociception (the transmission of physiological pain). RTX causes a novel ion channel in the plasma membrane of sensory neurons, the transient receptor potential vanilloid 1, to become permeable to cations, most particularly the calcium cation. This evokes a powerful irritant effect followed by desensitization and analgesia. (1)

Targets

Target Details
1. Transient receptor potential cation channel subfamily V member 1
General Function:
Transmembrane signaling receptor activity
Specific Function:
Ligand-activated non-selective calcium permeant cation channel involved in detection of noxious chemical and thermal stimuli. Seems to mediate proton influx and may be involved in intracellular acidosis in nociceptive neurons. Involved in mediation of inflammatory pain and hyperalgesia. Sensitized by a phosphatidylinositol second messenger system activated by receptor tyrosine kinases, which involves PKC isozymes and PCL. Can be activated by endogenous compounds, including 12-hydroperoxytetraenoic acid and bradykinin. Acts as ionotropic endocannabinoid receptor with central neuromodulatory effects. Triggers a form of long-term depression (TRPV1-LTD) mediated by the endocannabinoid anandamine in the hippocampus and nucleus accumbens by affecting AMPA receptors endocytosis (By similarity). Activation by vanilloids, like capsaicin, and temperatures higher than 42 degrees Celsius, exhibits a time- and Ca(2+)-dependent outward rectification, followed by a long-lasting refractory state. Mild extracellular acidic pH (6.5) potentiates channel activation by noxious heat and vanilloids, whereas acidic conditions (pH <6) directly activate the channel.
