Thiazolidinone-Heterocycle Frameworks: A Concise Review of Their Pharmacological Significance

Molecular hybridization is deemed an optimistic approach in drug design and the discovery of novel biologically active molecules as it may advance their affinity and potency while concurrently decreasing associated resistance and side effects. Approximately 20 % of approved drugs were developed using this approach in the past few years. Thiazolidinone is one of the privileged pharmacophores in medicinal chemistry and is associated with various biological activities; it forms a functional unit in several FDA-approved drugs. Consequently, this pharmacophore has attracted the attention of many research groups to further explore its pharmacological relevance by coupling it with other pharmacophoric moieties. This review presents a concise account of scholarly research exploits directed at the biological activities of newly synthesized thiazolidinone-tagged molecular hybrids. Focused attention is given to the existing structural activity relationship in each compound library and the toxicity profile of potent compounds including in silico docking studies (where applicable). This work would provide a base on which new pharmaceuticals with improved potency can be modelled.
