Pharmacological Screening of Cholinergic Drugs Using Daphnia magna Straus Hydrobionts as a Biological Test Object

Abstract

This work presents the results of primary pharmacological screening of anticholinergic drugs and comparative evaluation of their specific activity in equitoxic concentrations using Daphnia magna Straus hydrobionts as a biological test object. We determine the protective index and the minimum effective concentration in terms of preventing atypical motor hyperactivity of pharmacological substances when poisoning with a reversible acetylcholinesterase inhibitor. On the basis of the results obtained, the list of promising candidates for further research in warm-blooded animals is extended by all of the anticholinergic drugs previously selected in experiments on mammals.
