ABSTRACT: In the present study various thiosemicarbazides and thiosemicarbazones were synthesized and screened for their antimicrobial activity. Among the ligands tested, compounds 1, 3, 4 and 5 demonstrated inhibitory effects at 0.4 - 0.5 μM concentrations against E. coli while 1-(4-fluorobenzoyl)-N4-ethyl-thiosemicar-bazide (3) demonstrated the maximum inhibitory effective compound against E. coli, also possessing high water solubility. Instead, compound 3 demonstrated weak antibiotic effects against S. aurous while compounds 4 - 6 demonstrated significant antibacterial effects at 0.4 - 0.42 μM against the latter organism. Chloramphenicol was used as the positive control.
