Biological Activity

Description

Atropine sulfate monohydrate is a competitive antagonist for the muscarinic acetylcholine receptor, used to decrease the production of saliva and secretions of the airway prior to surgery.

Targets

mAChR ^[1]

2.5 nM

In vitro
In vitro	Atropine increases the release of the neurotransmitter dopamine into the superfusate in vitro at 100-500 mM and into the vitreous in vivo at 250 mg. Atropine induces spreading depression (SD) in the in vitro preparation. Atropine reduces the ERG b- and d-wave, leads to damped oscillations of RPE potentials, and reverses the ERG c-wave. Atropine suppresses myopia only at doses at which severe nonspecific side effects are observed in the retina. ^[1]

In Vivo
In vivo	Atropine (1.0 mg/kg, i.p.), but not methylatropine (1.0 mg/kg, i.p.), prevents the enhancement of retention induced by both doses of the anticholinesterase when given immediately after training in mice. ^[2] Atropine administration effectively prevents bradycardia and second-degree heart block but induces pulsus alternans and hypertension in dogs. ^[3] Atropine has no effect on handling-induced acetylcholine output in the presence of 10 nM neostigmine, but causes greater and longer increases in the presence of 100 nM and 1000 nM neostigmine in rats. ^[4] Atropine not only blocks the rapid eye movement (REM) sleep increases induced by CGS but it also tends to decrease REM sleep compared to atropine preceding saline in rats. ^[5] Atropine decreases the time to exhaustion by 67% in intact rats and by 96.2% in adrenodemedullated (ADM) and also reduces the exercise-induced pituitary prolactin (PRL) release in both intact (50%) and ADM rats (90%). ^[6]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
