Product Description
1-Hydroxypyrene is a biomarker of exposure to polycyclic aromatic hydrocarbons (PAHs) and is present in urine samples. 1-Hydroxypyrene is the primary biomarker of exposure to pyrenes.
1-Hydroxypyrene (1-OHP) is a monohydroxylated metabolite of pyrene and the most established and validated biomarker for assessing human exposure to carcinogenic polycyclic aromatic hydrocarbons (PAHs). It has a molecular formula of C16H10O and a molecular weight of 218.25. 1-Hydroxypyrene is analyzed in urine samples as the major biomarker of exposure to pyrenes. It functions as an orally active agonist for the aryl hydrocarbon receptor (AhR), which can contribute to renal fibrosis.
Biological Activity I Assay Protocols (From Reference)
Targets
1-Hydroxypyrene targets the aryl hydrocarbon receptor (AhR), a ligand-activated transcription factor that mediates the toxic effects of environmental pollutants. As an AhR agonist, it can activate AhR signaling, which may contribute to renal fibrosis. It has also been shown to inhibit DNA polymerase, RNA polymerase, and protein synthesis in vitro, and to inhibit mitochondrial dehydrogenases, leading to a decrease in cellular energy production.
ln Vitro
1-Hydroxypyrene exhibits in vitro activity as a biomarker of PAH exposure and as an AhR agonist. It inhibits DNA polymerase, RNA polymerase, and protein synthesis in vitro. It also inhibits mitochondrial dehydrogenases, leading to a decrease in cellular energy production. Its activity in the ER agonist pathway has been noted. These in vitro activities confirm its utility as a research tool for studying PAH toxicity and AhR signaling.
ln Vivo
In vivo, 1-hydroxypyrene is primarily used as a biomarker for PAH exposure. It is excreted in urine and can be used as an analytical marker for exposure to pyrene. Urinary 1-hydroxypyrene is extensively used in occupational health studies to monitor PAH exposure. Its presence in urine reflects recent exposure to PAHs, making it a valuable tool for environmental and occupational health research.
Enzyme Assay
In vitro assays for 1-hydroxypyrene are analytical rather than biological. The compound is measured in urine and other biological samples using high-performance liquid chromatography (HPLC) with fluorescence detection or liquid chromatography-mass spectrometry (LC-MS). Its levels are quantified to assess human exposure to PAHs. AhR activation can be assessed using reporter gene assays in cell lines expressing AhR.
Cell Assay
Cellular assays for 1-hydroxypyrene are used to study its effects on AhR signaling and cellular metabolism. Cells are treated with the compound, and AhR target gene expression (e.g., CYP1A1) is measured by qPCR. Mitochondrial function is assessed by measuring oxygen consumption or ATP production. Cytotoxicity assays can be performed to assess its effects on cell viability.
Animal Protocol
In vivo animal experiments with 1-hydroxypyrene are primarily conducted for toxicological and biomarker studies. The compound is administered to animals, and its levels in urine and tissues are measured to validate its use as a biomarker for PAH exposure. Its effects on AhR signaling and renal function can be studied in animal models of PAH toxicity.
ADME/Pharmacokinetics
1-Hydroxypyrene is a small, lipophilic molecule with a molecular weight of 218.25 and a molecular formula of C16H10O. It is excreted in urine as a metabolite of pyrene. Its pharmacokinetic properties are related to its role as a PAH metabolite; it is formed in the liver and excreted in urine. The compound is typically stored at room temperature.
Toxicity/Toxicokinetics
1-Hydroxypyrene is considered a biomarker of PAH exposure and is not typically evaluated for toxicity as a compound itself. However, as an AhR agonist, it may contribute to PAH-associated toxicities such as renal fibrosis. The compound is intended for research and analytical applications only and is not approved for human therapeutic use. Standard laboratory safety precautions should be followed when handling this compound.

Solubility Data
Solubility (In Vitro)
DMSO : ~50 mg/mL (~229.08 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (11.45 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (11.45 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
