| 产品介绍 |
Costunolide is a sesquiterpene lactone isolated from Magnolia sieboldii. The compound is described to act as an antioxidant, anti-mycobacterial, anti-inflammatory, and anti-viral, with cytotoxic activity. Additionally, Costunolide is reported to inhibit the activity of TERT (telomerase). Studies indicate that Costunolide activates JNK downstream of ROS in leukemia cells, and upstream of Bcl-2. The compound has also been suggested to act as an inhibitor of NOS (nitric oxide synthase) and the VEGFR KDR/Flk-1 signaling pathway |

Costunolide, a sesquiterpene lactone, exhibits anti-inflammatory and anti-oxidant properties and mediates apoptosis.
in vitro: Costunolide significantly inhibited RANKL-induced BMM differentiation into osteoclasts in a dose-dependent manner without affecting cytotoxicity. Costunolide did not regulate the early signaling pathways of RANKL, including the mitogen-activated protein kinase and NF-κB pathways. However, costunolide suppressed nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) expression via inhibition of c-Fos transcriptional activity without affecting RANKL-induced c-Fos expression. The inhibitory effects ofcostunolide were rescued by overexpression of constitutively active (CA)-NFATc1 [1]. Exposure of T24 cells to costunolide was also associated with increased expression of Bax, down-regulation of Bcl-2, survivin and significant activation of caspase-3, and it |
