Overview

Lu AE98134, an activator of voltage-gated sodium channels , acts as a partly selective Na v 1.1 channels positive modulator. Lu AE98134 also increases the activity of Na v 1.2 and Na v 1.5 channels but not of Na v 1.4, Na v 1.6 and Na v 1.7 channels. Lu AE98134 can be used to analyze pathophysiological functions of the Na v 1.1 channel in various central nervous system diseases, including cognitive restoring in schizophrenia, et al.

In Vitro

Lu AE98134 (30 μM) promotes the current mediated by Nav v 1.1 channel, and it activates Na v 1.5 and to a lesser extent Na v 1.2 but has no effect on Na v 1.4, Na v 1.6 and Na v 1.7 currents in HEK cells expressing Na v 1.1, Na v 1.2, Na v 1.6, Na v 1.5, and Na v 1.7 by step-wise depolarizing voltages using the whole-cell patchclamp configuration. Lu AE98134 (30 μM) increases the excitability of FSINs by decreasing the threshold for action potentials.Intracellular depolarizing current pulses evokes repetitive firing of action potentials at frequencies, additionally, Lu AE98134 increases the excitability since each current pulse generated a higher number of spikes (163 spikes in control; and 230 spikes in Lu AE98134). MCE has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

The fast spiking inhibitory interneurons (FSINs) from Dlx5/6 +/− animals exhibit abnormal excitability because of a more depolarized spike threshold and broader action potentials. Lu AE98134 (30 μM) increases the excitability of FSINs neurons from normal and Dlx5/6 +/− animals by modulating several parameters characteristic for NaV 1.1 channels. The selective activation of FSINs by Lu AE98134 restores cognitive flexibility in adult Dlx5/6 +/− mice . MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Application Protocols

• Item-specific (Product Data):
  • No validated application protocols are provided for this item.
• General lab protocol guidance for small-molecule stocks (informative):
  • Stock preparation: Accurately weigh compound (allow vial to equilibrate to room temperature in a desiccator to prevent moisture condensation). Dissolve in anhydrous DMSO to a convenient concentration (e.g., 10 mM), vortex, and, if needed, sonicate briefly. Record exact concentration and solvent composition.
  • Aliquoting: Dispense into low-bind microtubes or plates (amber if light sensitive) to single-use aliquots. Avoid repeated freeze–thaw.
  • Working solutions: Dilute stocks into assay buffer with vigorous mixing to the desired final concentration, ensuring final DMSO content is controlled and consistent across wells.
  • QC check: Verify concentration by UV (if extinction coefficient is known) or LC–MS quantitative methods. Inspect visually for precipitation; if present, adjust solvent or concentration.
  • Documentation: Capture lot number, preparation date, operator, and storage location in ELN/LIMS.

Biological Roles

• Item-specific (Product Data):
  • No biological target, pathway, or endogenous role is specified for this item. Classified for research use only.
• General guidance (informative):
  • As a synthetic small molecule, Lu AE98134 is not expected to have an endogenous biological role. In research contexts, such compounds are typically evaluated for interactions with proteins, enzymes, receptors, transporters, or pathways of interest.
  • Prior to biological testing, establish compound integrity (LC–MS purity, absence of reactive impurities) and confirm concentration by an orthogonal method (e.g., UV with extinction coefficient or qNMR).
  • Be alert to nonspecific activities: aggregation-based inhibition, redox cycling, metal chelation, or membrane perturbation can confound results. Incorporate counterscreens and detergent controls where appropriate.
  • If literature targets for Lu AE98134 are identified in your program, document species differences, plasma protein binding, and potential off-target panels before interpreting phenotypic outcomes.

Buffer Applications

• Applicability:
  • Lu AE98134 is not a buffering reagent. No buffer system specifications are provided for this item.
• Practical notes for assay buffers (informative):
  • When formulating assay media containing small-molecule stocks (often in DMSO), maintain final DMSO ≤0.5–1.0% v/v to limit cosolvent effects on proteins/cells.
  • Use well-characterized buffers (HEPES, PBS, Tris) at appropriate pH and ionic strength for your biological system. Validate compound solubility in the chosen buffer, with or without co-solvent.
  • For pH-sensitive compounds (unknown here), pre-dissolve in DMSO or ACN and add slowly to vigorously stirred buffer to avoid local supersaturation and precipitation.
  • Filter-sterilize final assay solutions when needed and verify recovery by analytical measurement to check for adsorption losses.

Green Alternatives

• Context:
  • As a discrete small molecule supplied for research screening, Lu AE98134 itself is not a process solvent or bulk reagent. “Green alternatives” considerations mainly pertain to how it is handled and formulated in the lab, not replacement of the compound itself.
• Greener handling strategies (informative):
  • Prefer aqueous-compatible co-solvent systems (e.g., minimal DMSO with phosphate-buffered saline) for assays to reduce organic solvent usage.
  • For purification/analytics, consider ethanol or isopropanol in place of acetonitrile or dichloromethane where compatible, and use water-rich LC gradients to minimize solvent waste.
  • Implement microscale experimentation and high-throughput miniaturization to reduce material and solvent consumption.
  • Employ closed-cap, low-dead-volume vials and 96/384-well plates to limit evaporative loss and VOC emissions.
• Waste minimization:
  • Segregate halogenated vs non-halogenated waste streams; prefer non-halogenated systems when possible. Use solvent recycling for ACN/MeOH if available.
• Tradeoffs:
  • Lower-toxicity solvents may alter solubility or assay performance; validate recovery and potency after any solvent change.

Pharmaceutical Uses

• Item-specific (Product Data):
  • No excipient role, pharmacopeial status, or manufacturing use is specified. The product is labeled for research use only.
