TREMORTIN A - Reference Information
| Introduction | penicillins A(Penitrem A), it is a kind of fungal neurotoxin produced by specific Aspergillus (Aspergillus), ergot (Claviceps) and Penicillium (Penicillium), which can inhibit smooth muscle potassium ion channels, for the first time, it was isolated from the moldy diet that caused the neurological symptoms of sheep, which mainly invaded the central nervous system, and caused the animals to tremors, convulsions, and even death. |
| toxicity | Wilson et al. isolated tremor toxin from the feed of sheep poisoning mainly with neurological symptoms, the toxin acts on the dorsal spinal cord, causing increased stress, tremors and convulsions in experimental animals. The dose of penicillins A to induce tremor in mice was 0.25mg/kg body weight, and the LD50 was 1.05 mg/kg by intraperitoneal injection. Tremor toxin is a neurotoxin, in addition, it can cause renal damage. |
| biological activity | Penitrem A is an indole diterpene neurotoxic alkaloid produced by Penicillium, it is a selective BK channel antagonist, which has anti-proliferative and anti-invasive effects on a variety of malignant tumors. Penitrem A can stimulate cerebral cortex synaptosomes to increase the spontaneous release of endogenous glutamic acid, GABA and aspartic acid, which can induce tremor syndrome in animals. |
| Target | BK channel |
