Application

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

Cellular oxidative stress is countered by enzymatic scavengers and antioxidant modulators against reactive oxygen species damage.

线粒体应激和ROS

氧化应激，在一部分上，是由多种细胞过程产生的活性氧介导，并由诸如酶清除剂或抗氧化剂调节剂等细胞抗氧化剂机制所控制的。自由基，如活性氧，会通过细胞引起细胞损伤。
