| Аннотация |
The mechanism of an antioxidant action of water-soluble polyol
- methanofullerenes С60[C9H10O4((OH)4]6 and С60[C13H18O4((OH)4]6, as the
mild uncouplers of an oxidative phosphorylation and respiration is
postulated. According to this mechanism, hydroxyl group of
methanofullerenols can aссept protons with the formation of oxonium
cations in acidic environment of intermembrane space of hyperpolarized
mitochondria. Protonation of fullerene derivatives is confirmed by the
decrease in their negative zeta potential in the pH below 5.4. Heavily
protonated methanofullerenols become positively charged and diffuse into
the mitochondrial matrix. As a consequence, the proton gradient is
disrupted, which causes a decrease in mitochondrial transmembrane
potential and reduction ROS production.
