Hydrogen transfer from artepillin C to cumylperoxyl radical proceeds via one-step hydrogen atom transfer rather than via electron transfer, the rate constant of which is comparable to that of (+)-catechin, indicating that artepillin C can act as an efficient antioxidant.

Enhanced radical-scavenging activity of naturally-oriented artepillin C derivatives.
More than two-fold augmentation in the radical-scavenging activity of artepillin C could be achieved via altering the O-H bond dissociation enthalpy of artepillin C by means of structuralExpand
Insights into the mechanisms and kinetics of the hydroperoxyl radical scavenging activity of Artepillin C
Through the single electron transfer mechanism, Artepillin C scavenges the hydroperoxyl radical in water approximately 572 times faster than Trolox.

The kinetics for the reaction of the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•) with artepillin C, a prenylated phenylpropanoid found specifically in Brazilian propolis, and its analogues was ex...
The protective effect of Artepillin C against lipid oxidation on model membranes
Abstract Brazilian green propolis is a well-known therapeutic product, commonly used in folk medicine. Artepillin C is the major compound of Brazilian green propolis and has received considerableExpand
The interaction of new plant flavonoids with rat liver mitochondria: relation between the anti- and pro-oxydant effect and flavonoids concentration.
TLDR
It is concluded that flavonoids extracted from algerian plants have some protecting effects against oxidative stress by protecting the mitochondria, since they acted as antioxidant and also as uncoupler at high concentrations, which is a risk for the cells. Expand

Capillary Electrophoresis Separation of Artepillin C: Determination in Brazilian Green Propolis.
TLDR
Capillary electrophoresis as an effective and reliable method for the analysis of artepillin C is desired as the standardized quality controls are essential before propolis or its biomolecules can be adopted routinely in nutraceuticals, food ingredients and therapeutic applications. Expand
Anti-inflammatory effects of a bioavailable compound, Artepillin C, in Brazilian propolis.
TLDR
Collectively, Artepillin C showed anti-inflammatory effects mediated, at least in part, by prostaglandin E(2) and nitric oxide inhibition through NF-kappaB modulation, and exhibited bioavailability by oral administration. Expand
