Biological Activity
IC50: 0.7 nM (hAChE), 7 μM (hBChE)[1]
Ambenonium chloride inhibits Acetyicholinesterase (AChE) in a rapidly reversible method, and shows strong inhibition with inhibition constant Ki of 0.12 nM against hAChE[1].
Ambenonium chloride shows inhibitory effect towards BChE with an IC50 value of 7 μM (hBChE)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Ambenonium chloride (6 mg/kg; p.o.; daily; 14 d) decreases the number of AChR in motorend-plates[3].

-
Animal Model:Female Sprague Dawley rats (weight 250 g) with myasthenia gravis[3]
-
Dosage:6 mg/kg
-
Administration:Oral gavage; daily; 14, 30, 60, 90, 360 days (Stop administration 24 h in advance)
-
Result:Resulted general activity decreasing and hypersensity to stimulation in rats during day 30-60, but these behaviors disappeared on day 90.
Induced degeneration and simplification of the postsynaptic folds, widening of the synaptic clefts, increased number of the postsynaptic vesicles, and reduction in the number of the AChR in the postsynaptic membrane on days 360.
