Description

General description

Atropine is isolated from Atropa belladonna, Datura stramonium and Mandragora officinarum. It is a tertiary amine, which acts as a cholinergic receptor antagonist.

Application

Atropine sulfate salt hydrate has been used:

• to assay specific binding of high-affinity 3-quinuclidinyl benzilate-3H ([³H]QNB) to the muscarinic acetylcholine receptor (mAChR)
• to block the recovery phase of the aldicarb (Ald) response
• as an analyte for liquid chromatography with tandem mass spectrometry (LC-MS/MS)
• as a mAChR antagonist to block acetylcholine receptor[1]

Biochem/physiol Actions

Competitive nonselective antagonist at central and peripheral muscarinic acetylcholine receptors.
