| Targets |
Midodrine-d6 hydrochloride targets the same pathways as the parent compound midodrine. Midodrine is a prodrug that is converted to its active form, desglymidodrine, in the liver. Desglymidodrine is an α1-adrenergic receptor agonist. The deuterium labeling in Midodrine-d6 does not alter the target specificity, as the isotopic substitution does not affect receptor binding. Its purpose is analytical rather than therapeutic.
|
|---|---|
| ln Vitro |
In vitro, Midodrine-d6 hydrochloride is not used for biological activity assays but as an internal standard in analytical chemistry. Its utility lies in its ability to co-elute with the native analyte (midodrine) while being distinguishable by mass spectrometry due to its +6 Da mass shift. This enables accurate quantification and correction for matrix effects in complex biological samples. The compound is used in the development and validation of bioanalytical methods.
|
| ln Vivo |
In vivo, Midodrine-d6 hydrochloride is not administered for therapeutic purposes. Its primary use is as an internal standard in pharmacokinetic studies to determine the bioavailability and metabolism of midodrine hydrochloride. By using the deuterated analog, researchers can accurately quantify the parent drug and its metabolites in biological samples, which is essential for understanding its pharmacokinetic profile in living organisms.
|
| Enzyme Assay |
For non-cell-based assays, Midodrine-d6 hydrochloride is used as an analytical standard. Its identity and purity are confirmed using techniques such as NMR, HPLC, and mass spectrometry. The compound's isotopic purity (≥99%) is verified. It is not used in receptor binding assays as it is not intended for pharmacological study. Its role is to serve as a quantitative tracer in analytical method development.
|
| Cell Assay |
For in vitro cellular assays, Midodrine-d6 hydrochloride is not typically used, as it is an analytical standard. However, it may be used in cell culture media as a part of sample preparation for LC-MS/MS analysis to quantify drug uptake or metabolism. The compound is added to biological samples (e.g., plasma, cell lysates) at a known concentration to serve as an internal standard, correcting for variability during sample processing and analysis.
|
| Animal Protocol |
For in vivo animal studies, Midodrine-d6 hydrochloride is used as an internal standard for the quantification of midodrine and its metabolites in pharmacokinetic studies. Blood or tissue samples collected from animals dosed with midodrine are spiked with a known amount of Midodrine-d6. The samples are then processed and analyzed by LC-MS/MS. The ratio of the signal of the analyte to that of the internal standard is used to calculate the concentration of the analyte, correcting for any losses during sample preparation.
|
| ADME/Pharmacokinetics |
Midodrine-d6 hydrochloride has a molecular weight of 296.78 and a molecular formula of C12H12D6N2O4·HCl. It is a stable isotope-labeled compound with a +6 Da mass shift relative to unlabeled midodrine. The compound is supplied as a solid and should be stored at -20°C for long-term stability. It is soluble in appropriate solvents for LC-MS/MS analysis. The compound is for research use only and is not intended for human consumption.
|
| Toxicity/Toxicokinetics |
The toxicity profile of Midodrine-d6 hydrochloride is not applicable, as it is used as an analytical standard at very low concentrations. The deuterium substitution is not expected to introduce new toxicities, as deuterium is a stable, non-radioactive isotope of hydrogen that is generally considered safe for research applications. The compound is not intended for human consumption. Standard safety precautions should be observed when handling the compound.
|
| Additional Infomation |
Midodrine-d6 hydrochloride is a stable isotope-labeled internal standard used in analytical and pharmacokinetic research. It is the deuterated form of midodrine hydrochloride, a medication primarily used to treat orthostatic hypotension. By using this internal standard, researchers can achieve precise quantification of midodrine and its active metabolite desglymidodrine in biological samples, supporting bioequivalence studies and therapeutic drug monitoring. It is available for research purposes only.
