| Targets |
Flibanserin-d4-1 targets serotonin receptors, specifically acting as a full agonist of the 5-HT1A receptor (Ki=1 nM) and an antagonist of 5-HT2A (49 nM). It also binds to dopamine D4 receptors (4-24 nM). Flibanserin has negligible affinity for a variety of other neurotransmitter receptors and ion channels. The compound is being investigated for HSDD.

| 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, Flibanserin-d4-1 is used as a tracer to study serotonin receptor binding and signaling. The compound does not exhibit intrinsic pharmacological activity beyond that of Flibanserin but serves as a quantitative tool for studying 5-HT1A agonism, 5-HT2A antagonism, and drug metabolism in cell-based systems. Flibanserin is a full agonist of 5-HT1A (Ki=1 nM). |
| ln Vivo |
In vivo, Flibanserin-d4-1 is used in pharmacokinetic and pharmacodynamic studies to trace the distribution and metabolism of Flibanserin in animal models. The deuterium label allows for precise quantification of the drug and its metabolites in plasma and tissues using mass spectrometry. The compound is used in research on HSDD and other disorders.
|
| Enzyme Assay |
As an internal standard, Flibanserin-d4-1 is used in analytical assays such as LC-MS/MS. Typical protocols involve spiking the labeled compound into biological samples prior to extraction and analysis. The labeled compound co-elutes with the unlabeled Flibanserin but is detected at a different mass-to-charge ratio, allowing for precise quantification and correction for matrix effects.
|
| Cell Assay |
In vitro cell-based experiments using Flibanserin-d4-1 involve treating cells expressing serotonin receptors with the compound and analyzing its uptake and metabolism by mass spectrometry. The compound can be used to study serotonin receptor signaling, drug-receptor interactions, and the pharmacokinetics of Flibanserin in various cell types.
|
| Animal Protocol |
In vivo animal studies using Flibanserin-d4-1 involve administering the compound to rodents via oral gavage. Blood samples are collected at various time points, and the concentration of the labeled compound is measured by mass spectrometry. Tissue distribution and metabolic profiling can also be performed.
|
| ADME/Pharmacokinetics |
Flibanserin-d4-1 exhibits pharmacokinetic properties similar to those of unlabeled Flibanserin. Flibanserin is orally bioavailable and has good brain penetration. It is metabolized in the liver and excreted primarily in urine. The deuterium label provides a distinct mass shift for analytical detection without significantly altering the compound's physicochemical properties.
|
| Toxicity/Toxicokinetics |
Flibanserin-d4-1 is considered safe for research use at typical concentrations. Unlabeled Flibanserin has been studied in clinical trials for HSDD and has a well-established safety profile but can cause adverse effects such as dizziness and somnolence. As a stable isotope-labeled compound, it is not intended for therapeutic use and is handled under standard laboratory safety practices.

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).
