In this study, four compounds containing 5-Fluoro-isatin thiosemicarbazone with methoxyphenyl or methoxyphenyl in different positions and zinc complexes were evaluated based on their biological activities. Compound 2 was the strongest compound affecting gramnegative bacteria compared to the other compounds. Also, this compound indicated better antimicrobial activity than positive control antibiotics. Besides, compound 3 was the only compound that inhibited the growth of Salmonella spp. such as Salmonella enteritidis ATCC 13076 and Salmonella typhimurium NRRLE 4463. 5-Fluoro-Isatin thiosemicarbazone and its derivatives also showed DNA protection property from moderate to good protections. Among them, compound 4 displayed the highest DNA binding affinity. These compounds possessed a capacity for utilization as drugs or drug additives based on their effects on bacteria strains and DNA binding affinity.false5-Fluoro-Isatin | Antimicrobial activity | DNA protection | ThiosemicarbazoneEvaluation of biological activity of 5-fluoro-isatin thiosemicarbazone derivativesEvaluation of Biological Activity of 5-Fluoro-Isatin Thiosemicarbazone DerivativesArticle10.22052/JNS.2020.03.00710.22052/JNS.2020.03.0072-s2.0-85091853796WOS:000577165100007509517102251-788X
