Abstract
- A series of deferiprone-resveratrol hybrids have been designed and synthesized as multitarget-directed ligands (MTDLs) through merging the chelating moiety 3-hydroxypyridin-4-one into the structure of resveratrol, a natural antioxidant agent and β-amyloid peptide (Aβ) aggregation inhibitor. The in vitro biological evaluation revealed that most of these newly synthesized compounds exhibited good inhibitory activity against self-induced Aβ 1–42 aggregation, excellent antioxidant activity and potent metal chelating capability. Compounds 3i and 4f were identified as the most promising MTDLs with triple functions, possessing micromolar IC 50 values for Aβ 1–42 aggregation inhibition, greater 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS •+ ) scavenging activity than Trolox and similar pFe(III) values to that of deferiprone.
