Lu AE98134, an activator of voltage-gated sodium channels, acts as a partly selective Nav1.1 channels positive modulator. Lu AE98134 also increases the activity of Nav1.2 and Nav1.5 channels but not of Nav1.4, Nav1.6 and Nav1.7 channels. Lu AE98134 can be used to analyze pathophysiological functions of the Nav1.1 channel in various central nervous system diseases, including cognitive restoring in schizophrenia, et al[1].
Lu AE98134 (30 μM) promotes the current mediated by Navv1.1 channel, and it 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 by step-wise depolarizing voltages using the whole-cell patchclamp configuration[1]. 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)[1].
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 NaV1.1 channels. The selective activation of FSINs by Lu AE98134 restores cognitive flexibility in adult Dlx5/6+/- mice[1].

The sodium channel activator Lu AE98134 normalizes the altered firing properties of fast spiking interneurons in Dlx5/6+/- mice
Neurosci Lett 2018 Jan 1;662:29-35.PMID:28987817DOI:10.1016/j.neulet.2017.10.004
Mental disorders such as schizophrenia are associated with impaired firing properties of fast spiking inhibitory interneurons (FSINs) causing reduced task-evoked gamma-oscillation in prefrontal cortex. The voltage-gated sodium channel NaV1.1 is highly expressed in PV-positive interneurons, but only at low levels in principal cells. Positive modulators of Nav1.1 channels are for this reason considered potential candidates for the treatment of cognitive disorders. Here we examined the effect of the novel positive modulator of voltage-gated sodium channels Lu AE98134. We found that Lu AE98134 facilitated the sodium current mediated by NaV1.1 expressed in HEK cells by shifting its activation to more negative values, decreasing its inactivation kinetics and promoting a persistent inward current. In a slice preparation from the brain of adult mice, Lu AE98134 promoted the excitability of fast spiking interneurons by decreasing the threshold for action potentials. We then tested if Lu AE98134 could normalize the altered firing properties of FSINs in Dlx5/6+/- mutant mice. FSINs of this model for schizophrenia are characterized by broader action potentials and higher spike threshold. We found that in the presence of Lu AE98134, the firing frequency was increased while the spike duration and the threshold were decreased. Compounds with similar mode of action appear as promising candidates for restoring cognitive deficits present in schizophrenia.
