Abstract

A series of curcumin analogs (1–3, 5a–5t) was synthesized through the condensation of appropriately protected hydroxybenzaldehydes with acetylacetone, followed by deprotection. The antioxidant activity of these analogs was determined by superoxide free radical nitroblue tetrazolium and DPPH free radical scavenging methods and the polyhydroxycurcuminoids (5l–5s) displayed excellent antioxidant activity. These analogs ...
