Description
Phenserine ((-)-Eseroline phenylcarbamate) is a derivative of Physostigmine and is a potent, noncompetitive, long-acting and selective AChE inhibitor. Phenserine reduces β-amyloid precursor protein (APP) and β-amyloid peptide (Aβ) formation. Phenserine improves cognitive performance and attenuates the progression of Alzheimer's disease.

How to use
In Vitro:
Phenserine (1-25 μM; 48 hours; CHO APP751SW cells) treatment CHO APP751SW cell shows 18.6% reduction in cells treated with 10 μM of Phenserine, while 25 μM concentration of Phenserine reduces APP level by 51.4%.
In Vivo:
Phenserine (1-4 mg/kg; intraperitoneal injection; for 4 days; male Fischer-344 rats) treatment improves learning when cholinergic function has been impaired in a spatial memory task.
