| PENITREM A Usage And Synthesis |
| 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 | | Chemical Properties | Solid | | Occurrence | A series of closely related metabolites of Penicillium crustosum has recently been isolated and the components separated chromatographically. Penitrem A forms colourless crystals from EtOH. | | Uses | Penitrem A is a tremorgenic mycotoxin isolated from Penicillium species. Penitrem A is a selective blocker of high-conductance Ca2+-activated potassium channels. | | Uses | Penitrem A has been used as Ca2+-Activated K+ (BK) channel blocker to study its effect on BK current in bag cell neurons. | | 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. | | References | References/Citations: |
