Based on 2 publication(s) in Google Scholar
Piromelatine (Neu-P11) is a melatonin MT1/MT2 receptor agonist, serotonin 5-HT1A/5-HT1D agonist, and serotonin 5-HT2B antagonist. Piromelatine (Neu-P11) possesses sleep promoting, analgesic, anti-neurodegenerative, anxiolytic and antidepressant potentials. Piromelatine (Neu-P11) also possesses pain-related P2X3, TRPV1, and Nav1.7 channel-inhibition capacities.

Piromelatine (5-50 mg/kg, ip, daily) decreases plasma glucose significantly[2].
Piromelatine (100 mg/kg) decreases thermal hyperalgesia and mechanical allodynia in PSL (partial sciatic nerve ligation) mice[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Twenty four male Sprague-Dawley rats (3 months old, weighing 250-300 g)[1].
-
Dosage:20 mg/kg.
-
Administration:IP, daily at 8:00 p.m.
-
Result:Resulted in significantly decreased plasma glucose levels (6.670.35 mmol/L, 6.770.34 mmol/L vs. 8.27 0.38 mmol/L), and the plasma glucose levels of the two groups were even neared to that of the normal control group (6.07±0.35 mmol/L).
Resulted in a decrease in triglycerides and total cholesterol levels (51.8% and 43.0%, respectively) and an elevation in HDL-C level (increase of 32.4%).
-
Animal Model:Five groups of 12-wk-old rats (10/group)[2].
-
Dosage:5-50 mg/kg.
-
Administration:Intraperitoneal injection in 18:00 every day.
-
Result:Plasma glucose was decreased significantly by 27.3%, 34.5% and 61.5%, respectively.
-
Animal Model:Male C57BL/6 J mice, weighing 22-26 g (10 weeks old; PSL mice)[3].
-
Dosage:25, 50, or 100 mg/kg.
-
Administration:IP 1 h before assessment of thermal hyperalgesia and mechanical allodynia.
-
Result:Remarkably prolonged thermal latency (surgery×treatment interaction, F1,24=15.7, p<0.001; surgery×treatment×hours interaction, F5,120=3.0, p<0.05) and increased mechanical threshold (surgery×treatment interaction, F1,24=18.4, p<0.001; surgery× treatment×hours interaction, F5,120=2.6, p<0.05) for 4 h after administration of piromelatine to PSL mice.

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: ≥ 2.08 mg/mL (6.66 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (6.66 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
