By using the lH—NMR method and paramagnetic ions Pr3+, the incorporation into the liposome membrane of a series of biologically active single-chain (TGE-n) and double-chain (DGE-n) quaternary ammonium salts was studied. Corresponding compounds of both groups differed in their alkyl chain-length (n = 8,10,12,14 and 16). Minimal concentration CA of compounds TGE-n and DGE-n which caused total release of Pr3+ ions from the external layer of liposome membrane and the ratio of CA to the 4.5 mM extravesicular concentration of Pr3+ (CPr) used in experiments was determined. Based on the results obtained, one can conclude that the effectiveness of Pr3+ release from liposome membrane is (with n = 12,14 and 16) twice as high for double-chain compounds as for analogous single-chain compounds, and about 2.5 and 5 times higher for DGE-10 and DGE-8 than for TGE-10 and TGE-8, respectively.
