3126 Resiniferatoxin Resiniferatoxin (RTX) is a plant toxin and ultrapotent capsaicin analog that occurs in various species of plants, such as resin spurge (Euphorbia resinifera). It evokes a powerful irritant effect followed by desensitization and analgesia. (L1244) 57444-62-9 104826 C37H40O9 628.7081 White powder. Oral (ingestion) (L1817) ; dermal (L1817) Resiniferatoxin 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. (L1244) No indication of carcinogenicity to humans (not listed by IARC). Resiniferatoxin (RTX) is a plant toxin and ultrapotent capsaicin analog that occurs in various species of plants, such as resin spurge (Euphorbia resinifera). (L1244) Investigated for use/treatment in interstitial cystitis and urinary incontinence. Resiniferatoxin is a neurotoxin that targets afferent sensory neurons involved in nociception. It evokes a powerful irritant effect followed by desensitization and analgesia. (L1244) Resiniferatoxin evokes a powerful irritant effect followed by desensitization and analgesia.
