Abstract
Several new and known 2-(4-substituted phenyl)-3(2H)-isothiazolone derivatives with or without chloro substituent at C-5 position were synthesized and their in vitro antibacterial activity against selected Gram-negative and Gram-positive bacteria were evaluated using agar dilution method. Most of compounds exhibited moderate to high activities against tested microorganisms, and in comparison with the reference drugs some compounds showed comparable or higher activities. In contrast to results of the previous studies, some 5-chloro derivatives showed lower or comparable activities against some tested microorganism, in comparison with analogues without C-5 substitution. In general, most of the compounds bearing electron withdrawing group at 4-position of the phenyl ring were more active against Gram-positive and most of those having piperazine derivatives were more active against Gram-negative bacteria.
