Abstract:Zerumbone is a cyclic seaquiterpene and, a potential resource for natural materials-related diversityoriented synthesis (NMRDOS). Zerumbone, the main component of the essential oil of a wild ginger, Zingiber zerumbet Smith, showed strong reactivity with good chemo-, regio-, and stereoselectivity. To build the foundations for the industrial use of zerumbone, we examined conjugate addition, transannular reactions, ring cleavage, ring expansion, and asymmetric induction. The biological activity of zerumbone deriv… Show more
“…Accordingly, development of multitarget drugs has been proposed recently Csermely et al 2005). Zerumbone is a naturally occurring dietary compound and has been reported to (Sobhan et al 2013;Prasannan et al 2012;Abdelwahab et al 2012;Kitayama 2011;Yob et al 2011;Eguchi et al 2007). Although numerous studies have discovered the signaling pathways of zerumbone in several types of cancers, the primary targets and the crosstalk between key death programs have not been fully identified.…”

“…Zerumbone, a cyclic sesquiterpene, is the main component of Zingiber zerumbet Smith which has attracted extensive attention in the recent decade for anticancer activities (Prasannan et al 2012;Kitayama 2011;Yob et al 2011). Existing studies suggest that zerumbone can regulate numerous signaling pathways.…”
Zerumbone, a natural monocyclic sesquiterpene, is the main component of the tropical plant Zingiber zerumbet Smith. Zerumbone induced antiproliferative and apoptotic effects against PC-3 and DU-145, two human hormone-refractory prostate cancer (HRPC) cell lines. Zerumbone inhibited microtubule assembly and induced an increase of MPM-2 expression (specific recognition of mitotic proteins). It also caused an increase of phosphorylation of Bcl-2 and Bcl-xL, two key events in tubulin-binding effect, indicating tubulin-binding capability and mitotic arrest to zerumbone action. Furthermore, zerumbone induced several cellular effects distinct from tubulin-binding properties. First, zerumbone significantly increased, while paclitaxel (as a tubulin-binding control) decreased, Mcl-1 protein expression. Second, paclitaxel but not zerumbone induced Cdk1 activity. Third, zerumbone other than paclitaxel induced Cdc25C downregulation. The data suggest that, in addition to targeting tubulin/microtubule, zerumbone may act on other targets for signaling transduction. Zerumbone induced mitochondrial damage and endoplasmic reticulum (ER) stress as evidenced by the loss of mitochondrial membrane potential and upregulation of GRP-78 and CHOP/GADD153 expression. Zerumbone induced an increase of intracellular Ca(2+) levels, a crosstalk marker between ER stress and mitochondrial insult, associated with the formation of active calpain I fragment. It induced apoptosis through a caspase-dependent way and caused autophagy as evidenced by dramatic LC3-II formation. In summary, the data suggest that zerumbone is a multiple targeting compound that inhibits tubulin assembly and induces a crosstalk between ER stress and mitochondrial insult, leading to apoptosis and autophagy in HRPCs.

“…7 Zerumbone is a natural compound isolated from essential volatile oil of rhizomes from the edible wild ginger, Zingiber zerumbet (L.) Smith. 9 Although zerumbone was recently shown to have several favorable pharmacologic properties, poor water solubility has limited its therapeutic use. The solubility of zerumbone can be improved by incorporation into an NLC.…”
This investigation evaluated the antileukemia properties of a zerumbone (ZER)-loaded nanostructured lipid carrier (NLC) prepared by hot high-pressure homogenization techniques in an acute human lymphoblastic leukemia (Jurkat) cell line in vitro. The apoptogenic effect of the ZER-NLC on Jurkat cells was determined by fluorescent and electron microscopy, Annexin V-fluorescein isothiocyanate, Tdt-mediated dUTP nick-end labeling assay, cell cycle analysis, and caspase activity. An MTT (3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide) assay showed that ZER-NLC did not have adverse effects on normal human peripheral blood mononuclear cells. ZER-NLC arrested the Jurkat cells at G2/M phase with inactivation of cyclin B1 protein. The study also showed that the antiproliferative effect of ZER-NLC on Jurkat cells is through the intrinsic apoptotic pathway via activation of caspase-3 and caspase-9, release of cytochrome c from the mitochondria into the cytosol, and subsequent cleavage of poly (adenosine diphosphate-ribose) polymerase (PARP). These findings show that the ZER-NLC is a potentially useful treatment for acute lymphoblastic leukemia in humans.
“…In the last years, the monocyclic sesquiterpenoid α-humulene (also called α-caryophyllene) has received increased attention due to its anti-inflammatory and potential anti-cancerogenic properties Passos et al, 2007). In addition, it is a precursor in the biosynthetic route to zerumbone which itself shows striking anti-inflammatory and anti-cancerogenic effects (Kitayama, 2011;Prasannan et al, 2012). α-Humulene is a natural constituent of Humulus lupulus (Katsiotis et al, 1989) and the shampoo ginger plant Zingiber zerumbet (Yu et al, 2008).…”
