Brevetoxin-3 (PbTx-3) is a highly potent allosteric voltage-gated Na+ channel activator and has multiple active centers (A-ring lactone, C-42 of R side chain). Brevetoxin-3 (PbTx-3) has a high affinity to site 5 of the voltage-sensitive Na+ channels, inhibits the inactivation of Na+ channels and prolongs the mean open time of these channels. Brevetoxin-3 (PbTx-3) repeated exposures can lead to prolonged airway hyperresponsiveness (AHR) and lung inflammation. References: [1]. Jeglitsch G,et al.
