A sequiterpene lactone that inhibits telomerase

ChEBI: A germacranolide with anthelminthic, antiparasitic and antiviral activities.

Inhibitor of human telomerase activity (IC 50 = 65 μ M in MCF-7 breast cancer cells). Suppresses proliferation and induces apoptosis in a variety of human tumor cell lines. Selectively blocks endothelial cell proliferation induced by VEGF. Inhibits expression of iNOS and IL-1 β and disrupts NF κ B activation. Displays anti-inflammatory, antifungal and antiviral properties.

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dermatitis case occurred in a chemistry student after accidental exposure to costus oil (CJ Le Coz & JP Lepoittevin, unpublished results).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 a sesquiterpene lactone originally isolated from plants widely used in many herbal medicines. It has a variety of effects. Costunolide is a potent inducer of apoptosis, a potent anti-cancer agent, has anti-inflammatory, anti-viral, anti-fungal, antimycobacterial activity and has been shown to inhibit telomerase activity.
