| Targets |
Pitavastatin lactone targets the same enzyme as its parent drug. Pitavastatin is a potent competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis. The lactone metabolite is less active than the parent drug but is a major circulating metabolite in humans.
|
|---|---|
| ln Vitro |
In vitro, Pitavastatin lactone is characterized as a major metabolite of Pitavastatin. It is formed when the hydroxy acid form of Pitavastatin undergoes lactonization. The compound is less active as an HMG-CoA reductase inhibitor compared to the parent drug but is an important metabolite for pharmacokinetic studies.
|
| ln Vivo |
In vivo, Pitavastatin lactone is a major circulating metabolite following Pitavastatin administration. It is formed in the liver and may contribute to the overall pharmacokinetic profile of the parent drug. The compound is used as a reference standard for analytical method development and quality control applications.
|
| Enzyme Assay |
In vitro assays for Pitavastatin lactone typically involve analytical method development using HPLC or LC-MS. The compound is used as a reference standard to identify and quantify the metabolite in Pitavastatin samples. Its retention time and mass spectrum are characterized for method validation.
|
| Cell Assay |
For in vitro cell-based assays, Pitavastatin lactone is not typically used, as it is a metabolite and not a pharmacological agent. It could be used to study its potential effects on HMG-CoA reductase activity if necessary, but its primary role is as an analytical reference standard. Cell viability and other cellular effects are not typically assessed for this compound.
|
| Animal Protocol |
In vivo animal studies with Pitavastatin lactone are not typically performed, as it is a metabolite and not a therapeutic candidate. Its use is confined to analytical and pharmacokinetic studies. The compound is used as a reference standard for the quantification of Pitavastatin and its metabolites in biological samples.

| Solubility (In Vitro) |
DMSO : ~100 mg/mL (~247.86 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: 2.5 mg/mL (6.20 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), Suspended solution; with ultrasonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of DMSO stock solution (25.0 mg/mL) to 900 μL of 20% SBE-β-CD saline and mix well. 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. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.20 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 DMSO stock solution (25.0 mg/mL) to 900 μL of corn oil and mix well. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
