| Targets |
The primary target of Pentoxifylline-d6 is not the compound itself but the parent drug Pentoxifylline, which is a non-selective phosphodiesterase (PDE) inhibitor. Pentoxifylline has immunomodulatory, anti-inflammatory, hemorheologic, antifibrinolytic, and antiproliferative effects and is used to treat peripheral vascular diseases. Pentoxifylline-d6 is used as an internal standard for the quantification of Pentoxifylline.

| 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].
Pentoxifylline-d6 itself does not exhibit direct in vitro biological activity because it is a stable isotope-labeled internal standard. However, the parent compound Pentoxifylline is a non-selective PDE inhibitor with immunomodulatory and anti-inflammatory effects. Pentoxifylline-d6 is used as an internal standard to accurately measure Pentoxifylline concentrations in biological samples. |
| ln Vivo |
Pentoxifylline-d6 is not intended for in vivo administration as a therapeutic agent; it is used as an analytical standard. The in vivo activity of the parent compound Pentoxifylline is well documented as a hemorheologic agent. Pentoxifylline-d6 is utilized in pharmacokinetic studies to track the distribution, metabolism, and excretion of Pentoxifylline in biological systems.
|
| Enzyme Assay |
In vitro enzyme/receptor binding assays for Pentoxifylline-d6 are not typically performed, as it is an analytical standard. Instead, the compound is used in analytical method development and validation. Quality control assays involve HPLC or LC-MS/MS to verify isotopic purity (≥98 atom % D) and chemical purity. The compound is tested for stability under various storage conditions.
|
| Cell Assay |
Pentoxifylline-d6 itself is not tested in in vitro cellular assays for biological activity, as it is an analytical standard. Its utility is assessed by its performance as an internal standard in analytical workflows, including its ability to provide accurate quantification in LC-MS/MS analyses. The compound is used in quality control applications for Pentoxifylline analysis.
|
| Animal Protocol |
In vivo animal studies for Pentoxifylline-d6 are not conducted as therapeutic efficacy studies. Instead, the compound is administered to animals as a tracer in pharmacokinetic studies to quantify the parent drug Pentoxifylline in plasma, tissues, and excreta. These studies help determine the absorption, distribution, metabolism, and excretion (ADME) profile of Pentoxifylline.
|
| ADME/Pharmacokinetics |
Pentoxifylline-d6 has a molecular formula of C13H12D6N4O3 and a molecular weight of 284.34. It has a purity of ≥98% and an isotopic enrichment of ≥98 atom % D. It appears as a solid. The compound is stable under recommended storage conditions. It is intended for research use only and is not for human consumption.
|
| Toxicity/Toxicokinetics |
The toxicity profile of Pentoxifylline-d6 is not extensively characterized, as it is an analytical standard rather than a therapeutic agent. The parent compound Pentoxifylline has well-established safety and toxicity profiles as a hemorheologic agent. Pentoxifylline-d6 is intended for research use only and is not approved for clinical use. Standard laboratory safety precautions should be followed when handling this compound.

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.
