The toxic effects of nanomolar AFB 1 metabolites on oxidative status and immune cells (neutrophils, monocytes, lymphocytes, and dendritic cells [DCs]) in mammals are represented by increased free radicals, inflammatory molecules, and mitochondrial pathways of cell apoptosis (via caspase-3/7/9 activation and ATP depletion) (8688)
QM/MM calculations Enzymesubstrate complexes were generated through molecular docking using the GOLD software 76 (ChemScore fitness function) on the crystal structure of PtGSTF8 preserving crystallographic Na + ions and flav-3-on-4-ol coordinates optimized at the B3LYP/6-31 G(d) quantum mechanical level (see below for details)
Below, we summarize novel therapeutic targets and strategies with clinical application potential to provide more options for disease treatment (Table 1)
