General description

Acetylcholine is a neurotransmitter released at nerve endings in both the central and peripheral nervous systems. Acetylcholine chloride (C7H16ClNO2) is a stable cholinergic agonist with muscarinic and nicotinic actions. It is available as white or off-white hygroscopic crystals, or as a crystalline powder. Acetylcholine chloride is hygroscopic in nature and is highly soluble in water, alcohol, propylene glycol and chloroform.

Application

Acetylcholine chloride has been used:
  • as an agent to trigger sudomotor axon reflex response during autonomic test
  • to induce contraction amplitude of pyloric circular smooth muscle strip (PCSMS) in rats
  • as a substrate for acetylcholinesterase
  • to stimulate after discharge in Aplysia bag cell neurons

Biochem/physiol Actions

Acetylcholine chloride, injected at 20 mg/kg body weight, reduces mortality and plasma proinflammatory cytokines in mice with experimentally-induced sepsis . The cholinergic anti-inflammatory mechanism is probably mediated by interaction of acetylcholine with α7n cholinoreceptor on monocytes, macrophages, and neutrophils, which decreases the levels of proinflammatory cytokines such as TNF-α, IL-1β, and IL-6.

Caution

Very hygroscopic
