    Abstract:
    Specifically synthesized group of benzimidazole derivatives possessing varying degrees of delocalization of the positive charge in the cation group of the molecule has been studied in order to search for potential cholinergically active compounds and to study the role of the Coulomb interaction in cholinesterase catalysis. These compounds were reversible inhibitors of cholinesterase (ChE) of human erythrocytes, horse serum, brain of the frog Rana temporaria and visual ganglia of the Pacific squid Todarodes pacificus in the presence of acetylthiocholine iodide and propionylthiocholine iodide as substrates. The differences in the nature of reversible inhibitory effect were observed. The effect of the inhibitor structure and substrate nature, specific for each of the studied inhibitors, on the character of the process of reversible inhibition was found.
