Spectrofluorometric and molecular docking studies on the binding of curcumenol and curcumenone to human serum albumin.[Pubmed:25756376]

Int J Mol Sci. 2015 Mar 6;16(3):5180-93.

Curcumenol and curcumenone are two major constituents of the plants of medicinally important genus of Curcuma, and often govern the pharmacological effect of these plant extracts. These two compounds, isolated from C. zedoaria rhizomes were studied for their binding to human serum albumin (HSA) using the fluorescence quench titration method. Molecular docking was also performed to get a more detailed insight into their interaction with HSA at the binding site. Additions of these sesquiterpenes to HSA produced significant fluorescence quenching and blue shifts in the emission spectra of HSA. Analysis of the fluorescence data pointed toward moderate binding affinity between the ligands and HSA, with curcumenone showing a relatively higher binding constant (2.46 x 105 M-1) in comparison to Curcumenol (1.97 x 104 M-1). Cluster analyses revealed that site I is the preferred binding site for both molecules with a minimum binding energy of -6.77 kcal.mol-1. However, binding of these two molecules to site II cannot be ruled out as the binding energies were found to be -5.72 and -5.74 kcal.mol-1 for Curcumenol and curcumenone, respectively. The interactions of both ligands with HSA involved hydrophobic interactions as well as hydrogen bonding.

Inhibitory effects of curcumenol on human liver cytochrome P450 enzymes.[Pubmed:20148399]

Phytother Res. 2010 Aug;24(8):1213-6.

Curcumenol, one of the major components of Zedoary turmeric oil, has been widely used to treat cancer and inflammation. As an antibiotic or anticancer drug, Curcumenol is highly likely to be used in combination with various synthetic drugs in most cases, thus it is necessary to evaluate potential pharmacokinetic drug-drug interactions induced by Curcumenol. In this study, the inhibitory effects of Curcumenol on seven CYP isoforms were investigated, and the results demonstrated that only CYP3A4 was strongly inhibited (IC(50) = 12.6 +/- 1.3 microM). Kinetic analysis showed the inhibition type was competitive with K(i) value of 10.8 microM. Time- and NADPH-dependent inhibitions were also investigated to show Curcumenol is not a mechanism-based inhibitor. Employing these in vitro data and maximum plasma concentration of Curcumenol in human predicted from beagle dog's in vivo pharmacokinetic data, the change in AUC of victim drugs was predicted to be 0.4%, which suggested that Curcumenol may be safely used without inducing metabolic drug-drug interaction through P450 inhibition. Nevertheless, due to the limited pharmacokinetic data available for Curcumenol in humans, it is still not possible to evaluate its potential clinical effects on human patients from in vitro data. Thus, the magnitude of drug-drug interaction (DDI) induced by Curcumenol warrants further investigation.
