Nonivamide
未知生产厂商
Nonivamide is found in herbs and spices. It is an alkaloid from the Capsicum species. The structures of Capsaicin and nonivamide differ only slightly with respect to the fatty acid moiety of the side chain (8-methyl nonenoic acid versus nonanoic acid) . Nonivamide is a flavoring ingredient. Nonivamide is an organic compound and a capsaicinoid. It is an amide of pelargonic acid and vanillylamine. It is naturally found in chili peppers but manufactured to produce a synthetic form for various pharmacologic preparations . This drug has been studied in combination with Nicarboxil in the treatment of lower back pain . Nonivamide has also been studied for its anti-inflammatory properties, as well as in fat loss therapies and has demonstrated promising results , , , .

Nonivamide is a naturally occurring analog of Capsaicin, isolated from peppers, described to produce effects similar to Capsaicin. It is an agonist of the VR1 (vanilloid/TRPV1 receptor) . It serves as a transient agonist of these receptors, which are potentiated by pro-inflammatory drugs, a phenomenon that leads to thermal hyperalgesia, or increased heat sensation . Nonivamide has been shown to stimulate afferent neurons with about half the potency of Capsaicin. Agonism of the VR1 (TRPV1) (vanilloid) receptor by Nonivamide was demonstrated to induce the release of Ca2+ from the endoplasmic reticulum (ER) of human lung cells, producing ER stress and cell death . Nonivamide, like other capsaicinoids, acts on the vanilloid receptors located in the peripheral afferent nerve fibers, providing short-acting irritant and algesic properties. Applied dermally, these substances act by stimulating sensitive chemoreceptors of the skin and by reflex, hyperemia and a local elevation in temperature. After repetitive administration, capsaicinoids have been reported to lead to desensitization to nociceptive stimuli possibly by long-acting depletion of peptide neurotransmitters (substance P) from peripheral sensory neurons. Capsaicinoids can modulate muscle tone (in bladder, bronchus etc.). Intravenous injection of nonivamide to rats (10 μg/kg) has been found to lead to bradycardia. The cardiovascular effects are partly explained by substance P release. Nonivamide given to rats subcutaneously (1 mg/kg) was found to cause body temperature decrease, vasodilatation, and increased salivation. Capsaicinoids have shown to illicit bronchospastic effects in guinea pigs. Capsaicin and its analogs were reported to increase barbiturate sleeping time in rats by interacting with hepatic metabolizing enzymes .
Nonivamide is used as a topical analgesic and is also used as a flavoring ingredient , , .
