Synthetic and medicinal perspective of thiazolidinones: A review

[Display omitted] •This review is focused on synthetic prospective of 4-thiazolidinones.•This review is also focused on medicinal prospective of 4-thiazolidinones.•It includes structure–activity relationship study of different activities. In the modern scenario, thiazolidinone scaffold has emerged as a very potent scaffold as per its clinical significance concerned. It has attracted the keen interest of the researchers due to its great diversity in biological activities. Thiazolidinones are the saturated form of thiazole, called thiazolidine with a carbonyl group. The 1,3-thiazolidin-4-ones possess wide range of pharmacological activities such as anti-cancer, anti-diabetic, anti-microbial, anti-viral, anti-inflammatory and anti-convulsant. In the past few years, various newer synthetic approaches have been designed to synthesize diverse scaffolds to explore the various types of biological activities. In this review, an attempt has been made by the authors to summarize various synthetic strategies for thiazolidinone derivatives as well as their biological significance.
