Brevetoxin-3
Based on 1 publication(s) in Google Scholar
Brevetoxin-3 (PbTx-3) is a 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.

Biological Activity
IC50: voltage-gated Na+ channel[1]
Brevetoxin-3 (PbTx-3)(30-500 nM) produces a shift in activation to more negative membrane potentials whereby single-channel activity is observed under steady-state conditions (maintained depolarization at -50 mV)[1].
