Biochem/physiol Actions

(-)-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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
