Abstract
Aim. To assess the effect of newly synthesized quaternary phosphonium salts with highest alkyl substituents (C10, C12, C14, C16, C18) on the permeability of cell membranes for sodium ions in vitro. Methods. In vitro studied was the effect of different concentrations of new quaternary phosphonium salts with highest alkyl substituents on the cell membrane permeability to sodium ions according to the rate of Na+-Li+-countertransport in the erythrocyte membrane. Results. Low concentration (0.001 mM) of substance C10 increased the rate of Na+-Li+-countertransport in the erythrocyte membrane by 11.9%, substance C12 - by 11.8%, substance C14 - by 12.7%, substance C16 - by 13%, substance C18 - by 12.3%. Higher concentrations of substances (0.01-0.05 mM) had no significant effect on the cell membrane permeability to sodium ions. Conclusion. An increase in the rate of Na+-Li+-countertransport in the erythrocyte membrane is influenced by minimal concentrations of a substance, under the influence of other concentrations the rate of Na+-Li+-countertransport doe not change.
