Abstract <p>Organic compounds play a crucial role in medicinal chemistry and chemical industry. Among them, Schiff bases formed by the condensation of aldehydes or ketones with amines are of significant importance. These compounds can be synthesized through various methods, including conventional heating, ultrasonic irradiation, catalyst-mediated processes, and microwave-assisted techniques. The azomethine linkage –HC=N– present in Schiff bases and their derivatives is associated with a wide range of pharmacological activities, such as anticancer, antioxidant, antimicrobial, antiviral, analgesic, anti-inflammatory, antidiabetic, and immuno­suppressive effects. In addition to their biological significance, Schiff bases are widely utilized in chemical industry. They serve as key intermediates in organic synthesis, as ligands in metal complex formation, and in the synthesis of amino acids. This review highlights the diverse applications of Schiff bases and aims to support the development of more potent molecular scaffolds for future drug design.</p>
