| In vitro |
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] |

| In vivo | 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.

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). Piroxicam, 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. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
