Potential Anti-Cancer Activities and Mechanisms of Costunolide and Dehydrocostuslactone

Costunolide (CE) and dehydrocostuslactone (DE) are derived from many species of medicinal plants, such as Saussurea lappa Decne and Laurus nobilis L. They have been reported for their wide spectrum of biological effects, including anti-inflammatory, anticancer, antiviral, antimicrobial, antifungal, antioxidant, antidiabetic, antiulcer, and anthelmintic activities. In recent years, they have caused extensive interest in researchers due to their potential anti-cancer activities for various types of cancer, and their anti-cancer mechanisms, including causing cell cycle arrest, inducing apoptosis and differentiation, promoting the aggregation of microtubule protein, inhibiting the activity of telomerase, inhibiting metastasis and invasion, reversing multidrug resistance, restraining angiogenesis has been studied. This review will summarize anti-cancer activities and associated molecular mechanisms of these two compounds for the purpose of promoting their research and application.     

微波法提取川木香中的木香烃内酯和去氢木香内酯的研究

∶微波法提取川木香中的木香烃内酯和去氢木香内酯,考察了微波功率、辐射时间、料液比对提取率的影响。最优工艺条件是微波辐射功率为400 W,辐射时间为3 min,料液比为1∶30(g/mL)。在此工艺条件下,提取率可以分别达到0.76%和2.31%。
