Isatin based materials can exhibit a wide range of biological activities including antimicrobial, antiviral, antifungal, anthelmintic, antitumor, anti-HIV, anti-inflammatory, antidepressant, antioxidant, anticonvulsant, antitubercular, analgesic, and central nervous system depressant activities. In this study, six compounds containing 5-Fluoro-isatin thiosemicarbazone with fluorophenyl and nitrophenyl or fluorophenyl and nitrophenyl in different positions and zinc complexes were evaluated based on their biological activities. 5-Fluoro isatin -3-(N-2- Fluorophenyl) Thiosemicarbazone and 5-Fluoro isatin-3-(N-4-Nitro phenyl) Thiosemicarbazone were the strongest compounds affecting gram positive bacteria compared to the other compounds. Also, this compound indicated better antimicrobial activity than positive control antibiotics. Besides, 5-Fluoro isatin-3- (N-4- Fluorophenyl) Thiosemicarbazone showed large inhibition zone equal to 13 mm against to some gram negative bacteria such as Klebsiella pneumonia and Serratia marrescens.
