PF-06526290 can both enhance and inhibit conduction through voltage-gated sodium channels.

ABSTRACT:

Background and purpose

Pharmacological agents that either inhibit or enhance flux of ions through voltage-gated sodium (Na_v ) channels may provide opportunities for treatment of human health disorders. During studies to characterize agents that modulate Na_v 1.3 function, we identified a compound that appears to exhibit both enhancement and inhibition of sodium ion conduction that appeared to be dependent on the gating state that the channel was in. The objective of the current study was to determine if these different modulatory effects are mediated by the same or distinct interactions with the channel.

Experimental approach

Electrophysiology and site-directed mutation were used to investigate the effects of PF-06526290 on Na_v channel functio
