Identification
Common Name Slaframine
Description Slaframine is a mycotoxin produced by the fungus Rizoctonia leguminicola. It is a parasympathomimetic compound and causes increased exocrine function, especially salivation. Along with swainsonine, the other biologially active compound of R. leguminicola, it is known to cause a condition called "slobbers syndrome" in livestock that has ingested contaminated feed.

Toxicity Profile
Route of Exposure Oral, dermal, inhalation, and parenteral (contaminated drugs). (W967)
Mechanism of Action Slaframine is a parasympathomimetic compound and causes increased secretion by salivary glands, pancreas, and other exocrine and endocrine glands. This is due to its activity as a cholingergic agonist. Slaframine has a high affinity for muscarinic receptors, especially in the gastrointestinal tract, and it stimulates these to produce its parasympathomimetic effects. Slaframine is also known to affect the concentration of circulating metabolic hormones, though the mechanism of this is unknown. (W956, W957)
Metabolism Slaframine is though to be activated in the liver by a hepatic microsomal flavoprotein oxidase to a ketoimine metabolite with a configuration similar to that of the parasympathetic neurotransmitter acetylcholine. (W957)

Health Effects Slaframine is a parasympathomimetic compound and causes increased exocrine function, especially salivation. Along with swainsonine, the other biologially active compound of R. leguminicola, it is known to cause a condition called "slobbers syndrome" in livestock that has ingested contaminated feed. (W956, W957)
Symptoms The major symptom of "slobbers syndrome" is profuse salivation. Other symptoms include diarrhea, lacrimation, stiff joints, frequent urination, tremors, spontaneous abortion, labored breathing, loss of appetite, bloat, and possibly death. (W957)
Treatment The effects of slaframine can be prevented by pre-treatment with an muscarinic receptor antagonist such as atropine or pirenzepine. (W957)

Targets

1. Muscarinic acetylcholine receptor M3

The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover.

Slaframine is a parasympathomimetic compound and causes increased secretion by salivary glands, pancreas, and other exocrine and endocrine glands. This is due to its activity as a cholingergic agonist. Slaframine has a high affinity for muscarinic receptors, especially in the gastrointestinal tract, and it stimulates these to produce its parasympathomimetic effects. (W956, W957)
