Synthesis and Antibacterial Activity of Bis[2-amino-4-phenyl-5-thiazolyl] Disulfides

Abstract

Different dimeric disulfides, having the basic skeleton of bis[2-amino-4-phenyl-5-thiazolyl] disulfides were synthesized in a straightforward manner from acetophenones. 2-Amino-4-phenyl-1,3-thiazoles were prepared by the reaction of thiourea with substituted acetophenones in the presence of iodine which were then converted to the title compounds. All the compounds were subjected to preliminary evaluation for their biological activity against Gram positive and Gram negative bacteria. Some of the assayed compounds showed marked activity against Bacillus cereus and Pseudomonas aeruginosa.
