SNX-482, Selective blocker of Cav2.3 channel
SNX-482 has been isolated from the venom of the Spider Hysterocrates gigas (African tarantula). SNX-482 modulates the R-type current associated with the class α1E calcium channel (Cav2.3 from the CACNA1E gene). SNX-482 antagonizes channel activation by inducing a depolarizing shift in the activation potential, thus preventing the channel from undergoing normal membrane depolarization. SNX-482 acts rapidly and maintains its effect.
