| Targets |
1-Hydroxypyrene-d9 does not have a specific pharmacological receptor target. As a stable isotope-labeled compound, it is used as an internal standard for the quantification of 1-hydroxypyrene in biological samples. 1-Hydroxypyrene itself is a metabolite of pyrene and is used as a biomarker of PAH exposure in humans.

| ln Vitro |
Drug compounds have included stable heavy isotopes of carbon, hydrogen, and other elements, mostly as quantitative tracers while the drugs were being developed. Because deuteration may have an effect on a drug's pharmacokinetics and metabolic properties, it is a cause for concern [1].
In vitro, 1-Hydroxypyrene-d9 is not used for biological activity assays. Its primary utility is as an internal standard in analytical chemistry. It is used to accurately quantify levels of 1-hydroxypyrene in biological samples such as urine, which serves as a biomarker for PAH exposure. The deuterium labeling provides a distinct mass shift for mass spectrometry detection. |
| ln Vivo |
In vivo, 1-Hydroxypyrene-d9 is not administered for therapeutic purposes. Its primary use is as an internal standard in analytical studies to quantify 1-hydroxypyrene levels in biological samples. By using the deuterated analog, researchers can accurately measure the concentration of this PAH metabolite in urine or other biological matrices for biomonitoring studies.
|
| Enzyme Assay |
For non-cell-based assays, 1-Hydroxypyrene-d9 is used as an analytical standard. Its identity and purity are confirmed using techniques such as NMR, HPLC, and mass spectrometry. It is not used in receptor binding assays. Its role is to serve as a quantitative internal standard for the analysis of 1-hydroxypyrene in biological and environmental samples.
|
| Cell Assay |
For in vitro cellular assays, 1-Hydroxypyrene-d9 is not typically used. It may be used in cell culture media as a part of sample preparation for LC-MS/MS analysis to quantify 1-hydroxypyrene uptake or metabolism in studies of PAH toxicity. The compound is added to biological samples at a known concentration to serve as an internal standard.
|
| Animal Protocol |
For in vivo animal studies, 1-Hydroxypyrene-d9 is used as an internal standard for the quantification of 1-hydroxypyrene in pharmacokinetic and metabolic studies. Urine or tissue samples collected from animals exposed to pyrene or other PAHs are spiked with a known amount of 1-Hydroxypyrene-d9. The samples are then processed and analyzed by LC-MS/MS.
|
| ADME/Pharmacokinetics |
1-Hydroxypyrene-d9 has a molecular weight of 227.28 g/mol and a molecular formula of C16H9DO (with nine deuterium atoms). It is a deuterium-labeled compound. The compound should be stored at -20°C for long-term stability. It is soluble in appropriate solvents for LC-MS/MS analysis. It is for research use only and is not intended for human consumption.
|
| Toxicity/Toxicokinetics |
The toxicity profile of 1-Hydroxypyrene-d9 is not applicable, as it is used as an analytical standard at very low concentrations. The deuterium substitution is not expected to introduce new toxicities, as deuterium is a stable, non-radioactive isotope of hydrogen. The compound is not intended for human consumption. Standard safety precautions should be observed when handling the compound.
