Abstract: Nowadays, the dilemma of drug resistance to antibacterial strains is of huge concern. Among the bacteria, Escherchia coli (E. coli) is the major pathogen, which is found in human and other animals. It is responsible for variety of severe diseases. A variety of commonly used antibiotics such as amoxicillin, gentamycin, etc and fluid replacement method are the suggested treatments for the infections caused by E. coli. In a study, it was established that the metal-based heterocyclic drugs demonstrated a different mode of action compared to the commonly used heterocyclic antibacterial drugs. Coumarin, an oxaheterocycle, is a privileged scaffold in medicinal chemistry. Metal complexes of coumarin-derived Schiff’s bases exhibit a broad range of pharmacological activities. Therefore, in the present review article, we have focused on the synthesis of metal complexes of coumarin derived Schiff’s bases as well as their respective Schiff’s base ligands and their antibacterial activities against the gram-negative bacterium E. coli.
