In the present study, the interaction of the protein structure of Escherichia coli DNA Gyrase-A (EcGyr-A) extracted from protein data bank (PDB Code: 1AB4) with ligands Nferrocenylmethyl-2-nitroaniline (2FMNA), N-ferrocenylmethyl-3-nitroaniline (3FMNA) and Nferrocenylmethyl-4-nitroaniline (4FMNA) were investigated by performing docking studies using the Molegro Virtual Docker (MVD) software. The results obtained showed that the best poses which is derived from MolDock score for Escherichia coli DNA Gyrase-A were respectively equal to -92.0111, -96.0866 and -95.6808 with reranking score equal to -40.9575, -73.4476 and -73.6423. Calculations revealed that 3FMNA react strongly with EcGyr-A followed by 4-FMNA and 2-FMNA.
