β-NETA

β-NETA is a potent and noncompetitive choline acetyltransferase (ChA; IC50=76 μM) and cholinesterase (ChE; IC50=40 µM) inhibitor. β-NETA weakly inhibits acetylcholinesterase (AChE; IC50=1 mM).

How to use

In Vitro:

β-NETA exhibits no effects at muscarinic receptors, ganglionic nicotinic receptors, skeletal muscular nicotinic receptors, cholinesterases or carnitine acetyltransferase at concentrations which inhibits ChA. At concentrations higher than the IC50 value to inhibit ChA, β-NETA antagonizes the effect of acetylcholine (ED50=100 µM), histamine and KCl-induced contractions in the guinea pig longitudinal ileal muscle.
