The scavenging activity of juglone and its derivatives is related to O-H bond dissociation enthalpy (BDE), ionization potential (IP), proton dissociation enthalpy (PDE), proton affinity (PA), and electron transfer enthalpy (ETE).
The phenolic OH bond dissociation enthalpy (BDE) represents reaction enthalpy of the HAT mechanism.According to this mechanism the lower BDE advocated easier dissociation of the phenolic OH bond.
We refined existing theoretical methods so we could accurately predict the chemical behaviour of antioxidants, based on the bond dissociation enthalpy (BDE) of the weakest, and hence most reactive, bond in each molecule (1).
(i) the bond dissociation enthalpy (BDE) characterizing the direct hydrogen atom transfer from the antioxidant (MJ-OH) to a free radical as
