Dehydrocostus Lactone is a major sesquiterpene lactone isolated from the roots of Saussurea lappa.IC50 value:Target:In vitro: Dehydrocostus Lactone promoted apoptosis with increased activation of caspases 8, 9, 7, 3, enhanced PARP cleavage, decreased Bcl-xL expression and increased levels of Bax, Bak, Bok, Bik, Bmf, and t-Bid. We have demonstrated that Dehydrocostus Lactone inhibits cell growth and induce apoptosis in DU145 cells . Dehydrocostus Lactone inhibits NF-kappaB activation by preventing TNF-alpha-induced degradation and phosphorylation of its inhibitory protein I-kappaB alpha in human leukemia HL-60 cells and that dehydrocostus lactone renders HL-60 cells susceptible to TNF-alpha-induced apoptosis by enhancing caspase-8 and caspase-3 activities . Dehydrocostus Lactone inhibited the production of NO in lipopolysaccharide (LPS)-activated RAW 264.7 cells by suppressing inducible nitric oxide synthase enzyme expression.In vivo: Dehydrocostus Lactone decreased the TNF-alpha level in LPS-activated systems in vivo .

This study evaluates the anticancer effects of dehydrocostus lactone, a plant-derived sesquiterpene lactone, on human chronic myeloid leukemia cells. Dehydrocostus lactone significantly inhibits cell proliferation by inducing cells to undergo cell cycle arrest, apoptosis, and differentiation. Dehydrocostus lactone suppresses the expression of cyclin B1, cyclin A, cyclin E, cyclin-dependent kinase 2 (CDK2), and cyclin-dependent kinase 1 (CDK1) and increases p21 expression, resulting in S-G2/M phase arrest in K562 cells. Dehydrocostus lactone also induces apoptosis by increasing the generation of reactive oxygen species (ROS), disruption of mitochondrial membrane potential (MMP), and modulating the protein levels of Bcl-2 family members. We also found that dehydrocostus lactone significantly inhibits the phosphorylation expression of Bcr/Abl, STAT5, JAK2, and STAT3 and downstream molecules including p-CrkL, Mcl-1, Bcl-XL, and Bcl-2 proteins in K562 cells. At a low concentration, dehydrocostus lactone significantly increased CD11b and CD14 expression on the surface of K562 cells, and induced cells to differentiate into monocytes or mature macrophages. Taken together, this study provides new insight into the molecular mechanisms of dehydrocostus lactone actions that may contribute to the chemoprevention of chronic myeloid leukemia. J. Cell.

Dehydrocostus lactone is considered to be the major cholagogic ingredient of the Costus genus of plants. It exhibits strong cholagogic effects, and also exerts antimicrobial and antineoplastic activity. The present study aimed to investigate the effects of dehydrocostus lactone on the cell growth and apoptosis of recombinant human papilloma virus (HPV)‑18 HaCaT cells. The HPV‑18 genome was transfected into HaCaT cells, which were subsequently used for analysis. The results demonstrated that dehydrocostus lactone reduced the cell proliferation and induced apoptosis of HPV‑18 HaCaT cells, as determined by MTT and N‑acetyl‑Asp‑Glu‑Val‑Asp p‑nitroanilide assays, respectively. Furthermore, caspase‑3/9 activity was determined using a caspase‑3/9 activity kit and western blotting was performed to investigate the expression of certain proteins. The results demonstrated that caspase‑3/9 activities, and the protein expression of Bcl‑2‑associated X and p53, in HPV‑18 HaCaT cells were significantly increased, while cyclin D1 protein expression was suppressed by dehydrocostus lactone. Additionally, dehydrocostus lactone significantly upregulated the protein expression of phosphatase and tensin homolog and inhibited the phosphatidylinositol 3‑kinase (PI3K)/Akt signaling pathway in HPV‑18 HaCaT cells. Therefore, the results of the present study indicate that dehydrocostus lactone may suppress cell growth and induce apoptosis in recombinant HPV‑18 HaCaT cells via the PI3K/Akt signaling pathway, and may be a represent a novel potential therapeutic agent for the treatment of condyloma acuminatum.

Acute lung injury (ALI) is a severe clinical disease marked by dysregulated inflammation response and has a high rate of morbidity and mortality. Macrophages, which play diverse roles in the inflammatory response, are becoming therapeutic targets in ALI. In this study we investigated the effects of dehydrocostus lactone (DHL), a natural sesquiterpene, on macrophage activation and LPS-induced ALI. The macrophage cell line RAW264.7 and primary lung macrophages were incubated with DHL (0, 3, 5, 10 and 30 μmol/L) for 0.5 h and then challenged with LPS (100 ng/mL) for up to 8 hours. C57BL/6 mice were intratracheally injected with LPS (5 mg/kg) to induce acute lung injury (ALI) and then treated with a range of DHL doses intraperitoneally (5 to 20 mg/kg). The results showed that DHL inhibited LPS-induced production of proinflammatory mediators such as iNOS, NO, and cytokines including TNF-α, IL-6, IL-1β, and IL-12 p35 by suppressing the activity of NF-κB via p38 MAPK/MK2 and Akt signaling pathway in macrophages. The in vivo results revealed that DHL significantly attenuated LPS-induced pathological injury and reduced cytokines expression in the lung. NF-κB, p38 MAPK/MK2 and Akt signaling molecules were also involved in the anti-inflammatory effect. Collectively, our findings suggested that DHL is a promising agent for alleviating LPS-induced ALI.
