Synthesis and anticancer properties of ‘Azole’ based chemotherapeutics as emerging chemical moieties: A comprehensive review

Azole frameworks serve as privileged scaffolds in the contemporary drug design paradigm owing to their unique physicochemical profile that promotes the development of highly selective, physiological benevolent chemotherapeutics. Several azole nuclei function as bioisostere in medicinal chemistry and prompt the development of tailored therapeutics for targeting the desired biological entities. Besides, the azole scaffold forms an integral part in the advanced drug designing methodologies, such as target template in-situ drug synthesis, that assists in rapid identification of the hit molecules form a diverse pool of leads; and direct biomolecule-drug conjugation, along with bioorthogonal strategies that ensure localization, and superior target specificity of the directed therapeutic. Lastly, the structural diversity of azole framework and high yielding click synthetic meth-ods provide a comprehensive Structure-Activity Relationship analysis for design optimization of the potential drug molecules by fine-tuning the placement of different substituents critical for the activity. This review provides a comprehensive analysis of the synthesis and anticancer potential of azole based chemotherapeutics.
