Description: |
Colupulone is an inducer of hepatic cytochrome P-4503A .Colupulone can increase cytochrome P450IIB and P450IIIA steady-state mRNA levels. Colupulone also has antibacterial effects. |
Targets: |
P450 (e.g. CYP17) | Calcium Channel | Sodium Channel | Potassium Channel | Antifection |
In vitro: |
J Appl Bacteriol. 1992 Apr;72(4):327-34. | Factors affecting antibacterial activity of hop compounds and their derivatives.[Pubmed: 1517174] | The antibacterial effect of weak acids derived from the hop plant (Humulus lupulus L.) increased with decreasing pH.
METHODS AND RESULTS:
Analysis of the minimum inhibitory concentration of such compounds against Lactobacillus brevis IFO 3960 over pH 4-7 suggests that undissociated molecules were mainly responsible for inhibition of bacterial growth. The antibacterial activity of trans-isohumulone was ca 20 times greater than that of humulone, 11 times greater than that of Colupulone and nine times greater than that of trans-humulinic acid when the degree of ionization was taken into account. Monovalent cations (K+, Na+, NH4+, Rb+, Li+) stimulated antibacterial activity of trans-isohumulone but the effect was smaller than that observed with H+.
The response to divalent cations varied: Ca2+ had little effect on antibacterial activity, whereas Mg2+ reduced activity. Lipid materials and beta-cyclodextrin also antagonized the antibacterial action of trans-isohumulone. |

In vivo: |
Food Chem Toxicol. 1994 Nov;32(11):1007-14. | The effect of colupulone (a HOPS beta-acid) on hepatic cytochrome P-450 enzymatic activity in the rat.[Pubmed: 7959454] | Colupulone, a component of hops, was examined for its ability to alter rat hepatic cytochrome P-450 enzymatic activity, expression of hepatic cytochrome P-450 mRNA, and in vitro promutagen activation.
METHODS AND RESULTS:
Colupulone was fed to male Sprague-Dawley rats for 5 days at 0.36% in the modified AIN 76 diet. Three cytochrome P-450 enzymatic activities were measured, and the corresponding steady-state mRNA levels were examined by Northern blot hybridization. Colupulone increased cytochrome P450IIB and P450IIIA steady-state mRNA levels. In vitro promutagen activation was measured in the Ames assay using liver homogenates from each treatment group. Colupulone treatment did not alter the ex vivo cytochrome P-450-mediated activation of aflatoxin B1 or benzo[a]pyrene to their mutagenic forms.
CONCLUSIONS:
The effect of long-term Colupulone administration on in vivo cytochrome P-450 enzymatic activity remains to be determined. |
