The effect of lactic acid (lactate) on Fenton based hydroxyl radical (*OH) production was studied by spin trapping, ESR, and fluorescence methods using DMPO and coumarin-3-carboxylic acid (3-CCA) as the *OH traps respectively. The *OH adduct formation was inhibited by
In Alzheimer's disease (AD), insoluble Aβ42 peptide fragments self-aggregate and form oligomers and fibrils in the brain, causing neurotoxicity. Further, the presence of redox-active metal ions such as Cu2+ enhances the aggregation process through chelation with these Aβ42 aggregates as
The chemotherapeutic potential of coumarin-3-carboxylic acid (C-3-COOH) and a series of three hydroxylated coumarin-3-carboxylic acid ligands, namely 6-hydroxy-coumarin-3-carboxylic acid (6-OH-C-3-COOH), 7-hydroxy-coumarin-3-carboxylic acid (7-OH-C-3-COOH) and 8-hydroxy-coumarin-3-carboxylic acid (8-OH-C-3-COOH), along with their corresponding silver-based complexes, namely 6-hydroxycoumarin-3-carboxylatosilver (6-OH-C-COO-Ag), 7-hydroxycoumarin-3-carboxylatosilver (7-OH-C-COO-Ag) and 8-hydroxycoumarin-3-carboxylatosilver
Aqueous solutions of highly stable supramolecular donor-acceptor complexes of chemically nonmodified pristine C(60) fullerene molecules with H(2)O molecules (hydrated C(60) fullerene-C(60)HyFn) and their labile nano-sized clusters were examined for their antioxidant effects on removal of hydroxyl radicals (.OH) and protecting
As part of an ongoing series of experimental charge-density investigations into the intra- and intermolecular interactions present in compounds which undergo solid-state [2 + 2] cycloaddition reactions, the charge-density analyses of trans-cinnamic acid and coumarin-3-carboxylic acid are reported. Thus, high-resolution
