DENSITY FUNCTIONAL THEORY STUDY OF THE ANTIOXIDANT ACTIVITY OF FORMLY CHROMONE SCHIFF BASES

Abstract

Antioxidant compounds in food play an important role as health-protecting factors. Scientific evidence suggests that antioxidants can reduce the risk for chronic diseases including cancer and heart disease. The main characteristic of an antioxidant is its ability to trap free radicals. Highly reactive free radicals and oxygen species are present in biological systems from a wide variety of sources. These free radicals may oxidize nucleic acids, proteins, lipids or DNA and can initiate degenerative disease. Antioxidant compounds scavenge free radicals such as peroxides, hydroperoxides or lipid peroxyls and thus inhibit the oxidative mechanisms that lead to degenerative diseases.

Chromone derivatives are abundant in nature and exhibit a wide range of pharmacological activity like anti-bacterial, anti-fungal, anti-cancer, anti-oxidant, anti-HIV, anti-ulcers [1,2]. Schiff bases of 3-formyl chromone also have a variety of applications in biological, clinical and pharmacological areas [3,4]. In this work, 3-((3-hydroxypyridin-2-ylimino)methyl)-4Hchromen-4-one (I) and 3-(-(2-mercaptophenylimino)methyl)-4H-chromen-4-one (II)[5] are
chosen to investigate the capacity of their antioxidant activity. In order to explain the antioxidant performance of these compounds, the BDE and electronic properties such as HOMO and LUMO energies, IP, hardness and sofness were computed and in detail.
