Abstract

We report the synthesis, antioxidant and antiproliferative activity and a QSARanalysis of synthetic diphenylpropionamide derivatives. Synthesis of these compounds wasachieved by direct condensation of 2,2- and 3,3-diphenylpropionic acid and appropriateamines using 1-propylphoshonic acid cyclic anhydride (PPAA) as catalyst. Compoundstructures were elucidated by NMR analysis and their melting points were measured. Thein vitro antioxidant activity of these compounds was tested by evaluating the amount ofscavenged ABTS radical and estimating ROS and NO production in LPS stimulatedJ774.A1 macrophages. All compounds were tested for their effect on viability of cells andresults demonstrated that they are not toxic towards the cell lines used. The cytotoxicactivity of all compounds was evaluated by a Brine Shrimp Test. View Full-Text
