    Suppression of Inflammatory cytokine production by ar-Turmerone isolated from Curcuma phaeocaulis.[Pubmed: 25044589 ]
    Rhizomes of Curcuma phaeocaulis Valeton (Zingiberaceae) have traditionally been used for controlling inflammatory conditions. Numerous studies have aimed to isolate and characterize the bioactive constituents of C. phaeocaulis. It has been reported that its anti-inflammatory properties are a result of cyclooxygenase-2 inhibition; however, its effect on the T-cell function remains to be elucidated.
    In this study, four known sesquiterpenoids, viz., ar-turmerone (TM), germacrone (GM), (+)-(4S,5S)-Germacrone 4,5-epoxide (GE), and curzerenone (CZ), were isolated from C. phaeocaulis rhizomes and evaluated for their effects on the CD4(+) T-cell function. While GM, GE, and CZ had no effect on the activation of splenic T cells or CD4(+) T cells, TM suppressed the interferon (IFN)-γ production, without affecting the interleukin (IL)-4 expression. TM also decreased the expression of IL-2 in CD4(+) T cells, but did not change their cell-division rates upon stimulation.
    These results suggest that TM, a major constituent of C. phaeocaulis rhizomes selectively exerts potent anti-inflammatory effects via suppression of the inflammatory cytokines IFN-γ and IL-2.

    Compounds isolated from Curcuma aromatica Salisb. inhibit human P450 enzymes.[Pubmed: 21287405 ]
    Curcuma species (Zingiberaceae) are used as both food and medicine in Asia. Ten sesquiterpenes (1-10) and two curcuminoids (11 and 12) were isolated from the rhizomes of Curcuma aromatica Salisb. and identified.
    The compounds were evaluated for their ability to inhibit cytochrome P450 (CYP). Among them, the sesquiterpene (4S,5S)-(+)-Germacrone 4,5-epoxide (7) inhibited certain subtypes of CYP more potently than or at levels comparable to the curcuminoids curcumin (11) and demethoxycurcumin (12); 7 (IC(50) = 1.0 ± 0.2 μM) > 12 (IC(50) = 7.0 ± 1.7 μM) > 11 (IC(50) = 14.9 ± 1.4 μM) for CYP3A4 inhibition; 12 (IC(50) = 1.4 ± 0.2 μM) > 11 (IC(50) = 6.0 ± 1.4 μM) > 7 (IC(50) = 7.6 ± 2.5 μM) for CYP2C9 inhibition; and 7 (IC(50) = 33.2 ± 3.6 μM) = 12 (IC(50) = 34.0 ± 14.2 μM) > 11 (IC(50) > 100 μM) for CYP1A2 inhibition.
    These results suggest the possibility that Curcuma aromatica Salisb. may cause food-drug interactions via cytochrome P450 inhibition by sesquiterpene 7 and curcuminoids 11 and 12.
