Noncrystal. | [Hazard]
Extremely toxic; deadly poison; neurotoxic; cardiotoxic activity; bara-chotoxin that blocks neuromuscular transmission; respiratory paralysis; death. | [Biological Activity]
Potent neurotoxin that activates voltage-gated sodium channels. Shifts voltage-dependent activation to more negative potentials, inactivation is disabled and pore conductance and selectivity are altered (displays increased permeability for NH 4 + , K + and Cs + ions). |
