Gene Information

Application

Atropine sulfate salt monohydrate has been used for anaesthetizing mice for intranasal administration of ropinirole or 7-OH-DPAT.

Biochem/physiol Actions

Atropine sulfate salt monohydrate is a competitive nonselective antagonist of central and peripheral muscarinic acetylcholine receptors. Atropine is a cholinergic receptor antagonist isolated from Atropa belladona L., Datura stramonium L. and other plants of the solanaceae family. It blocks the ion currents mediated by neuronal nicotinic acetylcholine receptors. Further, it blocks the acetylcholine (ACh)-induced relaxations in human pulmonary veins.
Competitive nonselective antagonist at central and peripheral muscarinic acetylcholine receptors.

1. To characterize the muscarinic receptors on human pulmonary veins associated with the acetylcholine (ACh)-induced relaxation, isolated venous and arterial preparations were pre-contracted with noradrenaline (10 microM) and were subsequently challenged with ACh in the absence or presence of selective

This study consists of two parts, first to compare the pharmacological profile of atropine and CEB-1957 substance toward muscarinic receptor subtypes. In various rat brain structures, binding properties were determined by competition experiments of [3H]pirenzepine, [3H]AF-DX 384, and [3H]4-DAMP in

Atropine, the classic muscarinic receptor antagonist, inhibits ion currents mediated by neuronal nicotinic acetylcholine receptors expressed in Xenopus laevis oocytes. At the holding potential of -80 mV, 1 microM atropine inhibits 1 mM acetylcholine-induced inward currents mediated by rat alpha2beta2
