Description and Uses
Costunolide is a germacranolide sesquiterpene lactone extracted from costus oil. With alantolactone and dehydrocostuslactone, it is a component of lactone mix used to elicit reactions in Compositae-sensitive patients. An erythema-multiform-like occupational contact dermatitis case occurred in a chemistry student after accidental exposure to costus oil (CJ Le Coz & JP Lepoittevin, unpublished results).
(+)-Costunolide is an inhibitor of osteoclast differentiation, acting as an anti-inflammatory and anti-oxidant agent. It is a sesquiterpene lactone which mediates apoptosis.
