Brevetoxin-3 (PbTx-3) is a potent allosteric voltage-gated Na+ channel activator. Brevetoxin-3 has a high affinity to site 5 of the voltage-sensitive Na+ channels, inhibits the inactivation of Na+ channels.
Hyperforin dicyclohexylammonium salt is a transient receptor canonical 6 channel activator with antidepressant effect. It modulates Ca2+ levels by activating Ca2+-conducting non-selective canonical TRPC6 channels.
VU0529331 is a modestly selective non-GIRK1-containing G protein-gated, inwardly-rectifying, potassium channel activator (EC50s: 5.1 µM and 5.2 µM for GIRK2 and GIRK1 2 in HEK293 cells, respectively). It is also effective on the GIRK4 homomeric channel.
