Synthesis and Antioxidant Evaluation of Indole Quinoline Derived Chalcones

Abstract

A series of novel indole quinoline derived chalcones were synthesized using cost-effective synergetic catalytic system consisting of heterogeneous basic bleaching earth clay (pH 12.5) and PEG-400 as solvent at ambient temperature with the yields of 60-76%. All these chalcones were characterized by spectral data. Both the DPPH and SOR scavenging assays were performed to evaluate their antioxidant nature of these compounds.
