Biological Activity:
Curcumol is a common traditional Chinese medicine with antitumor activities. Curcumol is isolated from Rhizoma Curcumae. Curcumol is one of the major components of the essential oil of Curcuma wenyujin with the structure of a guaiane-type sesquiterpenoid hemiketal. Curcumol exhibits clear antitumor, antihepatic fibrosis, antioxidant, and antimicrobial activities. Curcumol is one of the representative index components in the quality standard of the essential oil which is currently used as an anti-cancer and anti-virus remedy,and embodied in the Pharmacopoeia of the P.R.China(2005). Curcumol induced a rapid translocation of Bax from cytosol into mitochondria within 6 h, leading to a rapid dissipation of mitochondrial membrane potential (?Ψm), implying that mitochondria play an important role in the curcumol-induced apoptosis. The fact that Z-VAD-fmk, a broad-spectrum inhibitor of caspases, did not reduce the curcumol-induced apoptosis showed that caspases were not involved in curcumol-induced apoptosis, which was further verified by monitoring the caspase-3 activation inside living cells stably expressing SCAT3, a FRET plasmid. curcumol induced cell death in a dominant apoptotic fashion via the caspases-independent mitochondrial pathway in ASTC-a-1 cells.
