| Targets |
This compound is a structural analog of amlodipine and is expected to share a similar pharmacological target profile, acting on L-type voltage-dependent calcium channels. However, as a process impurity, it is not intended for therapeutic use and its specific biological activity is not the primary focus of study. The compound functions as an impurity reference standard rather than a pharmacologically active agent for in vivo applications.
|
|---|---|
| ln Vitro |
As an impurity reference standard, this compound is not evaluated for pharmacological activity in vitro. Its primary use is in analytical chemistry for the identification, quantification, and quality control of amlodipine besilate in pharmaceutical formulations. In vitro activity data, if any, would be limited to its potential cross-reactivity in analytical assays such as HPLC, where it serves as a marker for impurity profiling.
|
| ln Vivo |
This compound is not administered in vivo as a therapeutic agent. Its relevance is confined to pharmaceutical quality control and regulatory submissions. It does not possess pharmacological activity that would be evaluated in vivo. Any in vivo effects would be related to its presence as an impurity in amlodipine formulations, which are strictly controlled to ensure patient safety.
|
| Enzyme Assay |
The in vitro analytical procedure for amlodipine besilate impurity E typically involves high-performance liquid chromatography (HPLC) with UV detection. The compound is used as a reference standard to identify and quantify the impurity in amlodipine besilate samples. Its retention time and peak area are compared against a calibration curve to determine the impurity level, ensuring compliance with pharmacopoeial specifications.
|
| Cell Assay |
This compound is not used in cellular assays, as it is an impurity standard rather than a pharmacologically active substance. Its application is exclusively in chemical analysis for pharmaceutical quality control. No cellular activity data are available or relevant for this compound.
|
| Animal Protocol |
In vivo animal studies are not conducted for this impurity standard, as it is not a therapeutic agent. Its use is limited to analytical and regulatory purposes in pharmaceutical development. The compound does not have a pharmacological profile that would warrant in vivo testing.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties are not applicable to this compound as an impurity reference standard. It is not administered as a drug, and its absorption, distribution, metabolism, or excretion are not studied. Its relevance is purely analytical in the context of pharmaceutical quality control.
|
| Toxicity/Toxicokinetics |
Toxicological data for amlodipine besilate impurity E are limited, as it is not a therapeutic agent. Its presence is controlled as an impurity to ensure patient safety. The compound is considered a process-related impurity that must be monitored and controlled to meet regulatory limits, thereby minimizing any potential toxicological risk associated with its presence in amlodipine formulations.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*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.
