Phenserine tartrate ((-)-Eseroline phenylcarbamate) is a derivative of Physostigmine and functions as an efficient, non-competitive, long-acting, and selective inhibitor of acetylcholinesterase (AChE). This compound reduces the formation of amyloid precursor protein (APP) and β-amyloid peptides (Aβ), potentially improving cognitive abilities and alleviating the progression of Alzheimers disease.
