Innovative Horizons in Drug Design: Exploring the Synthesis and Medicinal Properties of Heterocyclic Schiff Bases. A Review

Schiff bases are an important scaffold for designing drug development. They are characterized by having a carbon-nitrogen double bond. This double bond is synthesized by different synthetic schemes by both the aromatic and aliphatic chains. Bases inspired chemists due to their versatile importance in drug discovery and drug development. A large number of drugs are designed through the heterocyclic Schiff base moieties. This review highlighted the importance of Schiff bases concerning their bioactive importance in drug design. Moreover, amide-iminol tautomerism is a significant tool for the high biological importance of Schiff bases due to the presence of the C=N bond. Furthermore, the reported synthesized heterocyclic scaffolds Schiff bases have a wide range of biological importance. Due to this different biological importance, such as antimicrobial, anticonvulsant, analgesic, antioxidant, antimalarial, anti-inflammatory, anticancer, antidiabetic, and antileishmanial properties, the researcher has shown their interest by synthesizing different heterocyclic Schiff bases. In this review article, biologically active heterocyclic Schiff bases were reviewed intensively concerning drug design and drug development.
