sesquiterpene

[¦ses·kwē′tər‚pēn]
(organic chemistry)
Any terpene with the formula C15H24; that is, 1½ times the terpene formula.

Sesquiterpene

 

any of the hydrocarbons with the general formula C15H24 (trimers of isoprene) or oxygen derivatives of these hydrocarbons. The name “sesquiterpenes” indicates that the molecular weight of these compounds is 1.5 times greater than that of the monoterpenes (from the Latin sesqui, “one and one-half times”). Sesquiterpenes, like terpenes, occur in essential oils and balsams and account for the characteristic odors of plants.

Methods: ALCL, leukaemia and breast cancer cells, and normal peripheral blood mononuclear cells (PBMCs) were treated with isolated sesquiterpene lactones and analysed for cell cycle progression, proliferation, mitochondrial activity, apoptosis, protein and mRNA expression, NF-[kappa]B and cytochrome P450 activity, 12(S)-HETE production and lymphendothelial intravasation.
Previous research with essential oils and lauraceous hosts suggests that [alpha]-copaene is the primary host attractant (kairomone), but other volatile sesquiterpenes may contribute; potential candidates include [alpha]-cubebene, [alpha]-humulene, [beta]-caryophyllene, [delta]-cadinene, and calamenene (Hanula & Sullivan 2008; Kendra et al.
