ANTIOXIDANT ACTIVITY AND DFT STUDIES OF ETHYL 2-(2-((6-METHYL-4-OXO-4H-CHROMEN-3-YL) METHYLENE)HYDRAZINYL)THIAZOLE-4-CARBOXYLATE

Abstract

  ABSTRACT. The microwave-assisted improved synthesis of ethyl 2-(2-((6-methyl-4-oxo-4H-chromen-3-yl)methylene)hydrazinyl)thiazole-4-carboxylate is described. The antioxidant potential of the target compound was evaluated using spectrophotometric methods, including the DPPH• and ABTS•⁺ radical scavenging assays, as well as three additional electron-transfer assays employing metal-based oxidizing agents. The title compound exhibited good antioxidant activity compared to reference antioxidants. For the title compound theoretical quantum chemical (DFT) calculations were performed
