A toxic alkaloid of the mushroom Amanita muscaria and certain other fungi. Although useful as a pharmacological tool, muscarine has no clinical or pesticidal applications. The compound is a potent and selective mimic of acetylcholine at parasympathetic neuromuscular junctions and at central muscarinic acetylcholine receptors. Symptoms of poisoning are primarily those attributable to peripheral parasympathetic stimulation (i.e., miosis, vomiting, diarrhea, bradycardia, and cardiovascular collapse). The i.v. LD50 in mice is 0.23 mg/kg.
