| Targets |
Atorvastatin-d5 hemicalcium is the deuterated form of atorvastatin, which is an orally active HMG-CoA reductase inhibitor. HMG-CoA reductase is the rate-limiting enzyme in cholesterol biosynthesis. By inhibiting this enzyme, atorvastatin effectively decreases blood lipids, including LDL-cholesterol and triglycerides.

| 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].
The in vitro activity of Atorvastatin-d5 hemicalcium mirrors that of atorvastatin, which is a potent HMG-CoA reductase inhibitor. Atorvastatin hemicalcium has the ability to effectively decrease blood lipids. The deuterated form is used as an internal standard in in vitro assays to accurately quantify atorvastatin. |
| ln Vivo |
In vivo, Atorvastatin-d5 hemicalcium is used as a tracer to study the pharmacokinetics and metabolism of atorvastatin. Atorvastatin is an orally active HMG-CoA reductase inhibitor with the ability to effectively lower blood lipids.
|
| Enzyme Assay |
The primary application of Atorvastatin-d5 hemicalcium is as an internal standard in LC-MS/MS analysis. A known amount of the labeled compound is added to biological samples (e.g., plasma or serum). Following protein precipitation and extraction, the sample is analyzed by LC-MS/MS. The internal standard corrects for variability in the analytical process.
|
| Cell Assay |
In cellular assays, Atorvastatin-d5 hemicalcium is used to quantify the intracellular concentration of atorvastatin. This allows researchers to study drug uptake and accumulation in cell lines.
|
| Animal Protocol |
In animal studies, Atorvastatin-d5 hemicalcium is utilized as an internal standard for the quantification of atorvastatin in pharmacokinetic studies. Following administration to animal models, blood samples are collected at various time points and analyzed by LC-MS/MS.
|
| ADME/Pharmacokinetics |
Atorvastatin-d5 hemicalcium is a chemically stable compound with a molecular weight of 583.71. It has an isotopic enrichment of 99.0% and a purity of ≥98.0%. It is stored as a solid at 2-8°C for long-term stability.
|
| Toxicity/Toxicokinetics |
Atorvastatin-d5 hemicalcium is intended for research use only and is not for therapeutic or diagnostic use in humans. As a stable isotope, it is non-radioactive and poses minimal radiological risk. Its toxicological profile is expected to be similar to that of atorvastatin, which is generally well-tolerated but may cause myopathy and hepatotoxicity.

*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.
