Dehydrocostuslactone (DHE) is a sesquiterpene lactone extracted from Saussurea lappa and Aucklandia lappa. The compound possess antifungal and antimycobacterial activity and exhibit a cytotoxic effect against HepG2, OVCAR-3, and HeLa cell lines.
Suppressors of cytokine signaling (SOCS) proteins negatively regulate cytokine receptor signaling. The SOCS family include eight members SOCS-1 to SOCS-7 and CIS. Dehydrocostuslactone (DHE) is a sesquiterpene lactone extracted from Saussurea lappa and Aucklandia lappa. The compound possess antifungal and antimycobacterial activity and exhibit a cytotoxic effect against HepG2, OVCAR-3, and HeLa cell lines. DHE inhibits cell proliferation not only in early-stage breast cancer MCF-7 but also in more advanced stage MDA-MB-231 cancer cells, without significant effect on H184B5F5/M10 normal mammary epithelial cells. The inhibition of breast cancer cells proliferation occurs through cell cycle blockade and apoptosis. DHE inhibits cell cycle progression and cell death through SOCS-1 and SOCS-3.

Aspergillus versicolor D-1 was employed to convert dehydrocostuslactone (1) and 3-hydroxy-1(10),3,11(13)-guaiatriene-12,6-olide-2-one (5) stereoselectively. The reactions occurring were specific hydrogenation on the exocyclic alpha,beta-double bond of sesquiterpene lactones with excellent conversion. Products were identified by the analysis of their spectra such

Oxidative stress regulates cellular functions in multiple pathological conditions, including bone formation by osteoblasic cells. To elucidate the protective effects of dehydrocostus lactone on the response of osteoblast to oxidative stress, osteoblastic MC3T3-E1 cells were incubated with 0.3mM hydrogen peroxide
