  • Highly potent TRPV1 agonist.
  • Resiniferatoxin (RTX) is a phorbol-related diterpene ester analog of capsaicin. RTX is a highly potent transient receptor potential vanilloid 1 (TRPV1) agonist (Ki=43pM) and acts as a selective modulator of primary afferent neurons. TRPV1 or vanilloid receptor 1 is a non-selective cation channel that is involved in the detection and transduction of nociceptive stimuli. TRPV1 is expressed in the plasma membrane of sensory neurons and stimulation by RTX causes this ion channel to become permeable to cations, especially calcium. The influx of cations causes the neuron to depolarize, transmitting signals similar to those that would be transmitted if the innervated tissue were being burned or damaged. This stimulation is followed by desensitization and analgesia, in part because the nerve endings die from calcium overload. Inflammation and nerve damage result in the up-regulation of TRPV1 transcription and therefore, modulators of TRPV1 channels are potentially useful in the treatment of inflammatory and neuropathic pain.

  • The primary action of RTX is to activate sensory neurons responsible for the perception of pain. RTX has been developed as an analgesic (painkiller) as a mean to provide pain relief for forms of advanced cancer. RTX has been investigated for treatment of urinary bladder hyper-reflexia, interstitial cystitis, rhinitis and chronic pain conditions. RTX has also been shown anti-inflammatory activity in T. spiralis infection, by inhibiting the Th1 immune response through the inhibition of Th1 cytokines in the intestinal phase.

  • Reduces myocardial ischemia-induced ventricular arrhythmias.
