Hemicholinium-3 (HC3), also known as hemicholine, is a
acetylcholine antagonist.[1]
Acetylcholine is synthesized from choline and a donated
acetyl group from acetyl-CoA, by the action of choline acetyltransferase (ChAT). Thus, decreasing the amount of choline available to a neuron will decrease the amount of acetylcholine produced. Neurons affected by hemicholinium-3 must rely on the transport of choline from the soma
(cell body), rather than relying on reuptake of choline from the synaptic cleft.
Toxicity
Hemicholinium-3 is highly toxic because it interferes with cholinergic neurotransmission. The LD50 of hemicholinium-3 for mice is about 35 μg.[2]
