애플리케이션

2,4-Dinitrophenol (DNP) can be used:
  • As a reactant for catalytic reduction reactions.
  • To activate carboxylic acids by converting them into dinitrophenyl (DNP) esters.
  • To prepare the corresponding ester via acylation reaction using isobutyric anhydride catalyzed by hafnium triflate.
  • As an effective cocatalyst to accelerate the activity and enantioselectivity of primary amine organocatalyst derived from natural primary amino acids for direct asymmetric aldol reaction.
  • As an alternative activator to tetrazoles in the reaction of phosphoroamidites with nucleosides.

Mitochondrial Stress and ROS

Oxidative stress is mediated, in part, by reactive oxygen species produced by multiple cellular processes and controlled by cellular antioxidant mechanisms such as enzymatic scavengers or antioxidant modulators. Free radicals, such as reactive oxygen species, cause cellular damage via cellular.
