Padsevonil
Based on 2 publication(s) in Google Scholar
Padsevonil (UCB0942) is a potent antiepileptic agent that selectively acts on presynaptic and postsynaptic targets. Padsevonil binds to synaptic vesicular protein 2 (SV2) with high affinity. Padsevonil is also a positive allosteric modulator and partial agonist of GABAAR, with high potency against α1 and α5 receptors. Padsevonil has antiepileptic effects in a variety of rodent models.

Padsevonil (0.01-30 µM) regulates GABAAR activity through allosteric sites on the receptor in CHO cells that stably express human α1β2γ2 GABAAR with an EC50 of 138 nM[1].
Padsevonil (0-30 µM) enhances natural GABAAR activity in a concentration-dependent manner in primary rat neurons with an EC50 of 208 nM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Padsevonil (0.14-30 mg/kg; intraperitoneal injection; single dose) has a protective effect in a rodent model of chronic epilepsy [2].

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 (5.78 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.
