Thiazole-Based Antioxidants: Pioneering a Decade of Therapeutic Advances

Background:: Thiazole-based compounds have attracted considerable interest due to their potent antioxidant abilities, which are crucial for combating diseases associated with oxidative stress. Over the last decade, significant progress has been made in the development and evaluation of thiazole derivatives exhibiting improved antioxidant properties. Objective:: This review aims to provide a comprehensive overview of the antioxidant properties of thiazole-derived compounds established over the past decade, emphasizing their SAR (Structureactivity relationships), mechanistic understanding, and potential therapeutic applications. Methods:: A comprehensive evaluation of peer-reviewed research from 2016 to 2025 was conducted, with an emphasis on studies investigating the antioxidant properties of thiazole-based compounds. SARs were evaluated to assess the effects of various substituents on antioxidant activity. Investigations into the mechanism were done further to understand the contribution of thiazole moieties in antioxidant activity. Results:: Various thiazole derivatives exhibited remarkable radical scavenging ability, frequently outperforming standard antioxidants. Structural characteristics including electron-donating substituents, catechol-containing scaffolds, and Schiff-base frameworks significantly improved activity. Metal complexes and hybrid structures enhanced the efficiency of electron transfer and the stability of radical intermediates. Discussion:: The findings indicate that thiazole derivatives exhibit antioxidant properties via synergistic structural and electronic characteristics that promote hydrogen-atom transfer along with single- electron transfer mechanisms. The integration of heterocyclic hybrids and metal coordination represents a promising strategy for the development of next-generation antioxidant agents characterized by enhanced stability and biological significance. Conclusion:: Over the last ten years, there have been significant advances in the development of thiazole-based antioxidants, including various derivatives exhibiting potent free radical scavenging capabilities. The results highlight the therapeutic efficacy of thiazole scaffolds in addressing diseases associated with oxidative stress. Future studies should focus on improving bioavailability and in vivo efficacy to facilitate the translation of these results into clinical applications.
