Antioxidant and antimalarial properties of butein and homobutein based on their ability to chelate iron (II and III) cations: a DFT study in vacuo and in solution
(Springer, 2016)A theoretical study on the antioxidant and antimalarial properties of butein and homobutein has been performed by considering their Fe2+ and Fe3+ chelation ability. In order to elucidate the origin of the antioxidant and ... -
Antioxidant enzyme activity is associated with blood pressure and carotid intima media thickness in black men and women: the SABPA study
(Elsevier, 2016)In the urbanized black population of South Africa, oxidative stress may play a crucial role in the development of hypertension. Since oxidative stress may result from impaired antioxidant capacity we aimed to investigate ... -
Antioxidant enzyme activity, proline accumulation, leaf area and cell membrane stability in water stressed Amaranthus leaves
(Elsevier, 2014)Traditional crops are extremely important for food production in low income, food-deficit countries (LIFDCs) where they continue to be maintained by socio-cultural preferences and traditional uses. Significant potential ... -
Antioxidant properties of 4-quinolones and structurally related flavones
(Elsevier, 2012)Neurodegenerative disorders are frequently associated with increased oxidative damage to the brain as a result of free radicals produced by cellular respiration. The onset and progression of neurodegeneration may therefore ... -
