In this article, we have been chosen benzene sulphonamide derivatives which had been synthesized and evaluated as anti-oxidants for QSAR study. We made mathematical relationship between (AOs) and three descriptors log(ω) electrophilicity , SCF and Mol Refractivity (IC50 = - 6.38 - 9.26 log (ω)- 0.00173 SCF - 0.235 Mol Refractivity). By this equation, the values of experimental (IC50) and estimated (IC50) using the QSAR model have the convergence between the two values. By using QSAR model we predict new compounds have effectiveness as antioxidants. For example, 2g and 2j which have (calculated IC50 =0.33578 and 0.3412), respectively.
