Application

Hemicholinium-3 has been used in the preparation of Krebs-HC-3 buffer to study its effects on choline uptake and choline acetyltransferase activity in differentiated human neuroblastoma (SK-N-SH) cells.

Biochem/physiol Actions

Hemicholinium-3 plays a role in blocking the neuronal choline uptake thereby inhibiting acetylcholine synthesis in the brain.
