Posiphen

Phenyl carbamoyl analogues of physostigmine-esrine were developed to provide longer acting and better tolerated Alzheimer's disease treatment. Posiphen (enantiomer of phenserine: ANVS401 (+)-phenserine) is under investigation in clinical trial NCT02925650 (Early Alzheimer's Disease) Posiphen does not inhibit AChE or BChE, but its major and minor metabolites (+)-N1-norPosiphen and (+)-N1,N8-bisnorPosiphen, respectively, possessed modest AChE inhibitory activity.
