Physostigmine (Synonyms: Eserine)

Cat. No.: HY-N6608
Handling Instructions

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

Description

Physostigmine (Eserine) is a reversible acetylcholinesterase (AChE) inhibitor. Physostigmine can crosses the blood-brain barrier and stimulates central cholinergic neurotransmission. Physostigmine can reverse memory deficits in transgenic mice with Alzheimer's disease. Physostigmine is also an antidote for anticholinergic poisoning[1][2][3][4].

In Vivo

Physostigmine (Eserine; 0.03-0.3 mg/kg; s.c.; daily for 6 weeks) improves deficits in contextual and cued memory in Tg(+) mice[2].
Physostigmine (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].

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.
