| Description | Capsaicin, also known as zostrix or axsain, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. Thus, capsaicin is considered to be a fatty amide lipid molecule. Capsaicin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Capsaicin is a potentially toxic compound. (6e)-n-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methylnon-6-enimidic acid is found in Capsicum annuum and Capsicum pubescens. (6e)-n-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methylnon-6-enimidic acid was first documented in 1996 (PMID: 8621114). For example, the mode of action of capsaicin in inducing bronchoconstriction is thought to involve stimulation of C fibers culminating in the release of neuropeptides (PMID: 17959343). |
