Solid | [Uses]
Penitrem A is a tremorgenic mycotoxin isolated from Penicillium species. Penitrem A is a selective blocker of high-conductance Ca2+-activated potassium channels. | [Description]
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 | [Definition]
ChEBI: Penitrem A is an organooxygen compound and an organic heterotricyclic compound. | [Biochem/physiol Actions]
Penitrem A intoxication causes ataxia, polypnea, and sustained tremors and may lead to seizures and death. Penitrem A affects the central and peripheral nervous system. It impairs the GABAergic neurotransmission in the cerebellum. | [Safety Profile]
Poison by ingestion and intraperitoneal routes. An experimental teratogen. When heated to decomposition it emits very toxic fumes of Clí and NOx. | [storage]
