Use of Phenserine

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[1][2][3].

Name	Phenserine,(3aS,8aR)-1,2,3,3a,8,8a-Hexahydro-1,3a,8-trimethylpyrrolo[2,3-b]indol-5-ol5-(N-phenylcarbamate)

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[1][2][3].

Target	AChE; β-amyloid precursor protein; β-amyloid peptide[1]
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%[2]. Western Blot Analysis[2] Cell Line: CHO APP751SW cells Concentration: 1 μM, 2.5 μM, 5 μM, 10 μM, 25 μM Incubation Time: 48 hours Result: 8.6% reduction in cells treated with 10 μM, while 25 μM concentration 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[3]. Animal Model: Male Fischer-344 rats (5 months old) induced by scopolamine[3] Dosage: 1 mg/kg, 2 mg/kg, 4 mg/kg Administration: Intraperitoneal injection; for 4 days Result: Improved morris water maze performance of scopolamine-treated rats..
