[Binding of phenyldicarbaundecaborane with proteins, membrane fragments, and whole cells].

The binding of the lipophilic synthetic anion, phenyldicarbaundecaboran, to inner and outer membranes of myocytes, platelets and erythrocytes as well as to integral and surface membrane proteins has been studied. It has been found that the distribution of lipophilic synthetic ions in the system biopreparations--aqueous phase is not determined by the value of the transmembrane difference of electric potentials but, rather, by ion adsorption by the protein-lipid components of the cell. The latter is controlled by the correlation between the volume of hydrophobic areas and the local electrochemical characteristics of the cell.
