Description and Uses
Penitrem A (12627-35-9) is a fungal mycotoxin that acts as a selective, irreversible blocker of the smooth muscle high conductance Ca2+-activated K+?(BK, KCa1.1) channel (100% block at 10 nM).1?Displays brain neurotoxicity in rats along with dose-dependent convulsions and death.2?An important tool for studying the role of BK channels in vascular function which is effective in cellular, tissue and?in vivo?experiments.3?Inhibits BK channels in inside-out and cell-attached patches, whereas iberiotoxin (considered the gold standard BK channel blocker) does not.3?May be used to partially ablate Purkinje cells in immature rat cerebellum providing a model for neural stem cell transplantation studies.4
Penitrem A has been used as Ca2+-Activated K+ (BK) channel blocker to study its effect on BK current in bag cell neurons.
