Brevetoxin-3 (PbTx-3) is a potent allosteric activator of voltage-gated Na+ channels. It demonstrates high affinity for site 5 on these channels, effectively inhibiting their inactivation and prolonging the mean open time. This compound is valuable for research into airway hyperresponsiveness and lung inflammation, as repeated exposure has been shown to induce these conditions. Brevetoxin-3 serves as a critical tool for studying sodium channel modulation and its implications in respiratory pathophysiology.
