| Targets |
Furosemide-d5 targets the same targets as furosemide, which is a potent orally bioactive Na+/K+/2Cl- (NKCC), NKCC1 and NKCC2 cotransporter inhibitor. Furosemide is also a GABAA receptor antagonist with 100-fold selectivity for α6-containing receptors over α1-containing receptors. Furosemide-d5 is not typically used for pharmacological studies of the target itself, but rather as an internal standard.

| 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 activity data for Furosemide-d5 are not typically generated, as the compound is primarily used as an internal standard. The biological activity of Furosemide-d5 is expected to be similar to that of furosemide, which inhibits NKCC cotransporters. However, Furosemide-d5 is not typically used for activity assays; its primary use is as an analytical standard. |
| ln Vivo |
In vivo studies using Furosemide-d5 are primarily pharmacokinetic in nature. The compound is used as an internal standard to study the pharmacokinetics of furosemide. Deuterium-labeled compounds are used to track the parent drug and its metabolites in biological samples.
|
| Enzyme Assay |
The use of Furosemide-d5 in in vitro experiments is primarily analytical. It is used as an internal standard in liquid chromatography-mass spectrometry (LC-MS) methods for the quantification of furosemide in biological samples. The compound is added to samples at a known concentration, and the ratio of furosemide to Furosemide-d5 is used to calculate the concentration of furosemide.
|
| Cell Assay |
In vitro cellular assays are not typically performed with Furosemide-d5, as the compound is primarily used as an analytical standard. If cellular studies were performed, they would be similar to those for furosemide, assessing NKCC inhibition or GABAA receptor antagonism. However, the primary use of Furosemide-d5 is in analytical chemistry.
|
| Animal Protocol |
Furosemide-d5 is used in pharmacokinetic studies in animals and humans. The compound is administered along with furosemide, and blood or tissue samples are collected at various time points. The concentration of Furosemide-d5 is measured by LC-MS. Pharmacokinetic parameters such as Cmax, Tmax, half-life, and AUC are calculated.
|
| ADME/Pharmacokinetics |
The pharmacokinetic properties of Furosemide-d5 are similar to those of furosemide, as the deuterium label does not significantly alter the compound's physicochemical properties. The compound has a molecular weight of 335.77. Furosemide-d5 is used as an internal standard in pharmacokinetic studies to accurately measure furosemide concentrations.
|
| Toxicity/Toxicokinetics |
Furosemide-d5 is a stable isotope-labeled compound with a molecular weight of 335.77. It is an off-white solid. As a labeled compound, it is not typically used for toxicology studies; its primary use is analytical. Furosemide-d5 is for research use only and not for human use.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
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.
