Definition

An organic heterotricyclic compound and guaianolide sesquiterpene lactone that is acrylic acid which is substituted at position 2 by a 4-hydroxy-3,8-bis(methylene)decahydoazulen-5-yl group and in which the hydroxy group and the carboxy group have undergone formal condensation to afford the corresponding γ-lactone.

Standard InChI

InChI=1S/C15H18O2/c1-8-4-7-12-10(3)15(16)17-14(12)13-9(2)5-6-11(8)13/h11-14H,1-7H2/t11-,12-,13-,14-/m0/s1

Biological Activity

Dehydrocostus lactone(DCL) is exuded from sunflower roots and low DCL concentrations stimulate germination of the root parasite Orobanche cumana.[1]
Dehydrocostus lactone(0.1-10microg/ml) can protect osteoblasts against H(2)O(2)
-induced cellular dysfunction, may be valuable as a protective agent against oxidative damage in osteoblasts.[2]
Dehydrocostus lactone increases cellular resistance to oxidant injury in HepG2 cells, may via causing the nuclear accumulation of the nuclear factor E2-related factor 2 (Nrf2) and increasing the promoter activity of antioxidant response element (ARE).[3]
Dehydrocostus lactone and costunolide exhibits strong larvicidal activity against A. albopictus with LC(50) values of 2.34 and 3.26 ug/ml, respectively, while the essential oil had an LC(50) value of 12.41 ug/ml. [4]
