[Effect of macrocyclic amidoesters on membranes].
A comparative analysis of new macrocyclic amidoesters effect on the bimolecular lipid membrane as well as on the electroexcitable membrane of snail isolated neurons was carried out. It was shown that the investigated complexes inducing a small change in lipid bilayer conductivity and some changes in Na-Ca neuron current characteristics produce essential changes of rapid potassium as well as late potassium current properties. It was concluded on the basis of these results and potassium compounds specificity that the investigated complexes interact directly with neuron potassium channels.
