OXIDATIVE STRESSAn imbalance between oxidants and antioxidants in favour of the oxidants, leading to a disruption of redox signaling and/or molecular damage.Sies H, Jones D. Encyclopedia of Stress (2007)

An antioxidant is any substance that is present in low concentrations
compared
to
those
of
an
oxidizable
substrate
and
significantly
delays
or
prevents oxidation of that substance.
Halliwell B, Gutteridge JMC (2007)
There

universal
antioxidants

any type of reactive oxygen species

Classification of Antioxidants
• Direct Antioxidants– Free radical scavengers (SOD/O2
‐.)
– Non radical scavengers (Catalase/H2
O2
)
• Indirect Antioxidants– Inhibitors of cellular sources of oxidants
(chelators/metals, apocynin/Nox)
– Inducers of cellular antioxidants (sulforaphane/Nrf2 targets‐GSH)
