Abstract:
An electrophoretically mediated microanalysis technique was developed for the rapid screening of acetylcholinesterase inhibitors. Activity of four original compounds, N-benzylpiperidine, carbamoyloxyphenyl derivatives and reference inhibitor--tacrine was determined and compared with the data obtained from Ellman's assay. Percentage of enzyme inhibition detected at inhibitor concentration of 3.33.10(-4) M was between 0 and 78% and was the highest for tacrine. The comparison of data obtained from the EMMA assay and Ellman's test proved inhibitory activity of novel compounds.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
