Befiradol
Based on 1 Customer Validation
Befiradol (NLX-112) is a highly selective 5-HT1A receptor agonist that acts on both presynaptic and postsynaptic sites. Befiradol attenuates fentanyl-induced respiratory depression in neonatal and adult rats. Befiradol reduces the duration of fentanyl-induced analgesia and sedation in adult rats. Befiradol can be used in studies related to opioid-induced respiratory depression.

5-HT1A Receptor |
Befiradol (1-30 μM) does not alleviate DAMGO-induced respiratory depression or alter baseline respiratory rhythm in vitro neonatal rat brainstem-spinal cord preparations[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Befiradol (0.1-0.4 mg/kg; intravenous injection; single bolus) dose-dependently attenuates fentanyl-induced respiratory depression and sedation in adult rats, but also significantly reduces fentanyl-induced analgesic effects at effective doses[1].
Befiradol (0.2 mg/kg; subcutaneous injection; single bolus dose) induces hyperventilation, hyperalgesia and behavioral syndrome in normal adult rats[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Sprague-Dawley (neonatal, 3 to 4 days after birth)[1]
-
Dosage:0.6 mg/kg
-
Administration:s.c.; single bolus
-
Result:Increased relative respiratory frequency to 39.2% of control (vs. saline 24.2% of control).
Increased relative tidal volume to 76.1% of control (vs. saline 52.2% of control).
Increased relative minute ventilation to 29.3% of control (vs. saline 12.4% of control).
Alleviated fentanyl-induced respiratory depression over 20 minutes.
-
Animal Model:Sprague-Dawley (adult male, 290 to 360 g)[1]
-
Dosage:0.1, 0.2, 0.4 mg/kg
-
Administration:i.v.; single bolus
-
Result:At 0.1 mg/kg, increased relative minute ventilation to 37.4% of control (vs. saline 18.7% of control) and oxygen saturation to 59.5% (vs. saline 45.7%) 4 minutes post-administration; alleviation lasted less than 10 minutes.
At 0.2 mg/kg, increased relative minute ventilation to 53.7% of control (vs. saline 18.7% of control) and oxygen saturation to 75.4% (vs. saline 45.7%) 4 minutes post-administration; alleviation lasted beyond fentanyl infusion duration.
At 0.4 mg/kg, increased relative minute ventilation to 65.8% of control (vs. saline 18.7% of control) and oxygen saturation to 78.5% (vs. saline 45.7%) 4 minutes post-administration; alleviation lasted beyond fentanyl infusion duration.
At 0.2 mg/kg, reduced duration of analgesia via tail clamping to 28.4 min (vs. saline 52.4 min) and via thermal paw withdrawal to 90.4 min (vs. saline 130.5 min).
At 0.2 mg/kg, reduced duration of fentanyl-induced sedation to 39.8 min (vs. saline 58 min).

Solvent & Solubility
DMSO : 50 mg/mL (126.95 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.35 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.35 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
