Biological Activity of Zederone

Description Zederone has anti-bacterial activity,it inhibits gram-positive bacteria activity. Zederone induces hepatotoxicity implicated the induction of Cyps, which leads to the formation of biological reactive metabolites and that cause the oxidative stress and liver cell injuries.
Targets TNF-α | Nrf2 | NADPH-oxidase | P450 (e.g. CYP17) | Antifection

Zederone, a sesquiterpene from Curcuma elata Roxb, is hepatotoxic in mice.[Pubmed: 24082031]

Int J Toxicol. 2013 Nov-Dec;32(6):454-62.

The present study aimed to investigate the hepatotoxicity of Zederone isolated from Curcuma elata in mice.
METHODS AND RESULTS:
Adult male mice were intraperitoneally injected with a single dose of Zederone (50-300 mg/kg body weight [BW]). Twenty-four hours after the injection, Zederone induced liver enlargement with scattered white foci over the organ. The medium lethal dose (LD??) value at 24 hours of Zederone was approximately 223 mg/kg BW. Hepatic centrilobular necrosis with marked increases in plasma alanine transaminase activity and total bilirubin levels was observed. Zederone at a dose of 200 mg/kg BW markedly decreased the activity of superoxide dismutase and the hepatic glutathione content, whereas the activity of catalase was not altered. The compound at this dose also increased the messenger RNA (mRNA) expression of Cyp2b10 and Cyp3a11, which are the main drug-metabolizing enzymes in the liver. The mRNA expression of proinflammatory cytokine tumor necrosis factor α was increased. The nuclear factor-E2-related factor 2 protein, which is the transcription factor regulating the antioxidant gene expression, was decreased.
CONCLUSIONS:
The histopathology of massive hepatic centrilobular necrosis with an increase in the expression of cytochrome P450 (Cyp) suggests that the possible potentiation of Zederone-induced hepatotoxicity implicated the induction of Cyps, which leads to the formation of biological reactive metabolites and that cause the oxidative stress and liver cell injuries.

Interactions of sesquiterpenes zederone and germacrone with the human cytochrome P450 system.[Pubmed: 23850985]

Toxicol In Vitro. 2013 Sep;27(6):2005-12.

Misclassification of Curcuma species (family Zingiberaceae) may lead to unwanted human exposure to Curcuma elata sesquiterpenes Zederone and germacrone which have caused hepatotoxicity and changes in CYP expression in laboratory animals.
METHODS AND RESULTS:
We investigated how these compounds interact with the human cytochrome P450 (CYP) system, in order to evaluate their potential for human liver toxicity and herb-drug interactions. We found that both sesquiterpenes (1-30 μM) greatly induced expression of CYP2B6 and CYP3A4 but not CYP1A2 mRNAs in human primary hepatocytes (HPHs). This induction profile correlated with activation of constitutive androstane and pregnane X receptors. Cytotoxicity was also observed in exposed HPHs. CYP inhibition studies with pooled human liver microsomes (HLMs) indicated that Zederone and germacrone moderately inhibited CYP2B6 and CYP3A4 activities in vitro, with IC50 values below 10 μM. When Zederone was incubated with HLMs and NADPH, one di-epoxide metabolite was formed and by using glutathione trapping, five epoxide-derived conjugates were detected. Germacrone produced two oxidized metabolites and four glutathione conjugates.
CONCLUSIONS:
The results suggest that enzymes in HLMs convert sesquiterpenes into reactive, electrophilic compounds which may be causative for the reported liver injuries. These findings provide insight on the safety and drug-herb interactions of the Curcuma species.
