Abstract
A homologous series of substituted benzenesulfonamides has been synthesized, and the minimum inhibitory concentration (MIC) against two strains of bacteria has been determined. It is shown that there is an approximately linear relationship between the MIC of the substituted benzenesulfonamides and the σ-Hammett values as well as the b values calculated from infrared-spectrophotometric data of the substituted anilines used for the synthesis of the benzenesulfonamides. Thereby it is possible to predict the in vitro activity of sulfonamides using either Hammett or b values of the basic amines.
