Cardiotoxin, protamine and polylysine are potent inhibitors of various cholinesterases. CaCl2 and MgCl2 overcome the inhibition. The order of addition of the inhibitor and the protecting agent (MgCl2) influences the final degree of the inhibition observed. These findings suggest that cardiotoxin, protamine and polylysine inhibit cholinesterases by the ionic binding of their basic groups with th...

The study was conducted to explore the anticholinesterase inhibition property of eugenol derived molecules. Ten derivatives were synthesized and evaluated for inhibitory activities against acetylcholinesterase (AChE) butyrylcholinesterase (BChE) by Ellman’s method. Most tested showed higher on BChE than AChE, however, their overall activity weak. In contrast, three (compounds 3,6,9) good AChE m...
