Metal complexes with ONS donor Schiff bases. A review

Schiff bases, usually synthesized from the condensation of an amino group with carbonyl compounds and their transition complexes have interesting chemistry and are widely used for industrial purposes exhibiting a broad range of biological activities, including antifungal, antibacterial, antimalarial, antiproliferative, anti-inflammatory, antiviral, and antipyretic properties. This review is focused on the use and properties of substituted Schiff bases with ONS donating sites and their metal complexes, discussing in brief about biological activities.
