Biochem./physiol. Wirkung

(-)-Phenserine, a phenylcarbamate derivative, is a selective, non-competitive inhibitor of acetylcholinesterase (AChE). (-)-Phenserine produces rapid, potent, and long-lasting AChE inhibition, in vivo. It is significantly less toxic than (-)-physostigmine. (-)-Phenserine improves cognitive performance in both young learning-impaired and elderly rats. Reduced secretion of β-amyloid (Abeta) has been observed in cell lines exposed to (-)-phenserine, occurring through translational regulation of β-amyloid precursor protein (beta-APP) mRNA via a non-cholinergic mechanism. These in vitro findings appear to translate in vivo into animal models and humans.

Acetylcholine Synthesis and Metabolism

Acetylcholine is synthesized from acetyl coenzyme A and choline by the enzyme choline acetyltransferase. In addition to its synthesis in the liver, choline employed in acetylcholine production is derived from dietary sources.
