title: [Effect of macrocyclic esters on mitochondrial and phosphatidylcholine membranes].
abstract: It has been found that some macrocyclic esters have no ionophoric properties, but can block valinomycin-induced potassium transport in mitochondrial membranes and lessen the potassium current induced by valinomycin in phosphatidylcholine bilayers. It has been also discovered that 36-member cyclic esters of succinic acid and propylene glycoles decrease fluorescence of puridine nucleotides in mitochondria and produce a modifying effect on bimolecular phosphatidylcholine membranes in the medium of litium, calcium and magnesium chlorides at unilateral injection. The results obtained suggest that cyclopolyesters under investigation form mixed complexes with the macromolecules in the composition of mitochondrial and phosphatidylcholine membranes with the participation of the integrated ion.
