Human erythrocyte membrane permeability for nonelectrolytes - series of amides
Abstract
Permeability coefficients for human erythrocyte membranes for a series of amides have been determined. When molecular diameter is greater than 4Å a significant decrease in aqueous permeability has been shown. Permeability coefficients of erythrocytes incubated with pCMBS which is known as a protein channel blocker, rise with a distribution coefficient increase between hydrophilic and hydrophobic phases for the series of amides with the correlation coefficient of 0.94. The results obtained give evidence that the substances investigated permeate erythrocyte membrane by two passes: through aqueous protein channels and directly through lipid phase.
