Toxicity Profile
Route of ExposureOral, dermal, inhalation, and parenteral (contaminated drugs). (2)
Mechanism of ToxicityPhallotoxins bind actin, preventing its depolymerization and poisoning the cell. They bind specifically at the interface between F-actin subunits, locking adjacent subunits together. This leads to a decrease in the rate constant for the dissociation of actin subunits from filament ends, which essentially stabilizes actin filaments through the prevention of filament depolymerization. Moreover, they inhibit the ATP hydrolysis activity of F-actin. (8, 1)
MetabolismNot Available
Toxicity ValuesLD50: >20 mg/kg (Mouse) (5)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesPhalloidin is one of a group of toxins from the death cap (Amanita phalloides) known as phallotoxins. (6)
Minimum Risk LevelNot Available
Health EffectsLiver lesions, tachycardia, hypoglycemia, hypotension and electrolyte imbalance with acid- base disturbance (7).
SymptomsHypovolemic shock; Gastrointestinal symptoms occur after a latent period and include abdominal pain, vomiting, and watery diarrhea. Neurologic symptoms are related to hepatic failure and may include encephalopathy, somnolence, confusion, coma and seizures (7).
TreatmentConsider gastric lavage and activated charcoal. (3)
