Abstrakt: In this work membrane fluidity alterations in synaptosomes, isolated from mice brain tissue, at chronic administration of neuroprotectors Dimebon and NT-1505 in vivo were studied. Membrane microviscosity was measured by electron paramagnetic resonance spin labeling of 2,2,6,6-tetramet-hyl-4-capryloyl-oxylpiperidine-l-oxyl (lipid probe) and 5,6-benzo-2,2,6,6-tetramethyl-1,2,3,4-tetrahydro-gamma-carboline-3-oxyl (near protein probe). It was shown that the neuroprotectors Dimebon and NT-1505 affect a membrane structure. Despite the difference in membrane structures, fluidity of the lipid bilayer in time returned to control values.
