Physostigmine hemisulfate
Based on 2 publication(s) in Google Scholar
Physostigmine hemisulfate (Eserine hemisulfate) is a reversible acetylcholinesterase (AChE) inhibitor. Physostigmine hemisulfate can crosses the blood-brain barrier and stimulates central cholinergic neurotransmission. Physostigmine hemisulfate can reverse memory deficits in transgenic mice with Alzheimer's disease. Physostigmine hemisulfate is also an antidote for anticholinergic poisoning.

Biological Activity
|
AChE |
Physostigmine hemisulfate (IV; 0.1, 0.2 mg/kg) delays time to emergence from isoflurane anesthesia at doses ≥0.2 mg/kg in male Sprague-Dawley rats[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Heterozygous transgenic mice (Tg(+) mice)[2]
-
Dosage:0.03, 0.1, and 0.3 mg/kg
-
Administration:SC; daily for 6 weeks
-
Result:Tended to normalize the contextual memory deficit in Tg(+) animals so that they became more similar to Tg(-) animals.
