[Interactions of aluminofluoride complexes (ALFx) with high-energy compounds (ADP, ATP) as revealed by molecular modeling].
BACKGROUND
Aluminofluoride complexes (AlFx) are toxic substances at the cellular and subcellular level, apparently implicated in degeneration of the nervous system. The present study focused on direct interactions with A1Fx of two common adenine nucleotides: adenosine diphosphate and adenosine triphosphate, both of which play an important role in many biochemical processes. The aim was to search for interactions between ADP-AlIF and ATP-AlFx complexes depending on the environment of the reaction.


METHODS
Modern HyperChem computer software was used allowing for the computation of heat of formation and bond energy. Results. The strongest bonds in vacuum were calculated for ADP-AIF4 ', ADP-AIF3 and ATP-AlF3. In water, the strongest bonds were found for ADP-AF3 and ATP-AlF3. Due to inhibition of metabolic processes, stable bonds between those molecules are less advantageous than labile ones. Nevertheless, strong bonds seem to be associated with reduced toxicity of AlFx complexes.
