Abstract:
Sesquiterpenoid lactones such as artemisinin from natural products have an important pharmaceutical potential. Dehydrozaluzanin C, a kind of guaianolide sesquiterpenoid lactone, is originally isolated from medicinal plants like A insliaea DC. However, the extremely low content in those plants limits its further development and utilization. So far the anti-cancer activity of Dehydrozaluzanin C remains largely unknown. In this study, Dehydrozaluzanin C was synthesized by a rapid and efficient method, and the anti-proliferative and apoptotic effects on human bladder cancer T24 cells were further investigated. Firstly, Dehydrozaluzanin C was synthesized beginning with dehydrocostuslactone in two steps including allylic and Dess-Martin oxidation, and the total yield was 73%. Furthermore, MTT assays showed that Dehydrozaluzanin C significantly inhibited the proliferation of bladder cancer T24 cells in a dose-dependent manner. Moreover, DAPI staining demonstrated that Dehydrozaluzanin C significantly induced the apoptosis of bladder cancer T24 cells. Mechanistically, western blot analysis further confirmed that the apoptotic effect of Dehydrozaluzanin C was associated with activation of the cleavage of PARP, leading to the apoptotic effect of T24 cells. Taken together, these findings suggest that guaianolide Dehydrozaluzanin C may be a promising lead compound for prevention and treatment of bladder cancer.
