ADWX-1 inhibits Kv1.3 channel with a high affinity and selectivity (IC50=1.89 pM)
Leuirotoxin binds to the SK channels (small conductance Ca2+-activated K+ channels)
This toxin blocks Kv1.3 channel with 11pM.
Apamin binds to and inhibits the SK channels (small conductance Ca2+-activated K+ channels) in the brain and spinal cord.
Kaliotoxin-1 is a selective inhibitor of BK channels
Tamapin binds to small conductance Ca2+-activated K+ channels (SK channels)
This toxin is a potent selective inhibitor of voltage-dependent potassium channels such as Kv1.3.
Tertiapin Q blocks the inwardly rectifying Kir1.1and Kir3.1/3.4 potassium channels
Charybdotoxin blocks voltage gated and Ca2+ activated K+ channels.
Guangxitoxin 1E: . GxTx-1E inhibits Kv2.1 with an IC50 value of 1 nM and Kv2.2 with an IC50 value of 3 nM.
It is one of the most potent toxins active on Kv1.3 channels (Kd close to 10 pM).
Maurotoxin inhibits Kv1.1, Kv1.2, Kv1.3 (preferentially Kv1.2) and apamin sensitive SK channels
