By step-wise depolarizing voltages using the whole-cell patchclamp configuration, Lu AE98134 (30 μM) promotes the current mediated by Navv1.1 channel, activates Nav1.5 and, to a lesser extent, Nav1.2, but has no effect on Nav1.4, Nav1.6, and Nav1.7 currents in HEK cells expressing Nav1.1, Nav1.2, Nav1.6, Nav1.5, and Nav1.7[1]. Lu AE98134 (30 μM) lowers the action potential threshold, increasing the excitability of FSINs. Repeated firing of action potentials at specific frequencies is induced by intracellular depolarizing current pulses. In addition, Lu AE98134 increases excitability because each current pulse produces a greater number of spikes (163 in control and 230 in Lu AE98134) [1].

ln Vivo |
Fast spiking inhibitory interneurons (FSINs) from Dlx5/6+/− mice had wider action potentials and a greater depolarized spike threshold, which causes aberrant excitability. Lu AE98134 (30 μM) modulates various characteristics characteristic for NaV1.1 channels, increasing the excitability of FSINs neurons from both normal and Dlx5/6+ /− mice. In mature Dlx5/6+/− mice, selective FSIN activation by Lu AE98134 restores cognitive flexibility[1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.89 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.89 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
