Xanthohumol

Xanthohumol, a prenylated chalcone from hop, inhibits COX-1 and COX-2 activity and shows chemopreventive effects. Xanthohumol inhibits diacylglycerol acyltransferase 1 (DGAT1) and DGAT2 with both IC50 of 40 μM. Xanthohumol is also a potent antiviral agent against a series of DNA and RNA viruses. Xanthohumol induces growth inhibition and apoptosis in cancer cells. Phase 1.

Xanthohumol inhibits Cyp1A activity and induces QR activity in mouse hepatoma cell culture. Xanthohumol scavenges reactive oxygen species and inhibits superoxide anion radical and nitric oxide production. In addition, Xanthohumol prevents carcinogenesis via inhibition of DNA synthesis and induction of cell cycle arrest in S phase, apoptosis, and cell differentiation. [1] Xanthohumol shows potent anti-HIV-1 activity. [2]

Kinase Assay Inhibition of Cox Activity
Inhibition of Cox-1 activity is measured by monitoring oxygen consumption during the conversion of arachidonic acid to PGs using a Clark-type O2-electrode. The reaction mixture contains ∼0.2 units Cox-1 in 100 μL of microsome fraction derived from ram seminal vesicles as a crude source of Cox-1 (specific activity 0.2–1 units/mg protein) or 0.23 units of recombinant human Cox-2 (specific activity 43 units/mg protein). For calculation, the rate of O2 consumption is compared with a DMSO control (100% activity). CP-16171, a nonsteroidal anti-inflammatory drug, is used as positive inhibitory substance for Cox-1 activity with an IC50 of 0.35 ± 0.05 μM (n = 2). Alternatively, nimesulide, a Cox-2 specific inhibitor, inhibits Cox-2 activity by 52 ± 5.7% (n = 2) at a concentration of 50 μM.

Concentrations 12.5 μM
Incubation Time 96 h
Method

HL-60 cells are maintained in RPMI 1640 supplemented with 10% FBS at 37°C in a 5% CO2 atmosphere. Log-phase cells with a population doubling time of 14–16 h are used for experiments. Serial 2-fold dilutions of compounds (dissolved in DMSO, final concentration 0.1%) in a final concentration range of 0.2–12.5 μM are prepared in 24-well plates using 1 ml of RPMI/well. Control wells obtain the same amount of solvent. Subsequently, 1 ml of the cell suspension is added to the wells. After 96 h, the experiment is evaluated. Cell numbers are counted using a Casy 1 TTC flow-cytometer. The proliferation of treated cells is expressed as a percentage in comparison with the solvent control.

In CETP-Tg mice, xanthohumol (p.o.) prevents cholesterol accumulation leading to atherosclerosis. [3] In TRAMP mice, xanthohumol (p.o.) induces a decrease in the average weight of the urogenital (UG) tract, delays advanced tumor progression and inhibits the growth of poorly differentiated prostate carcinoma.
