Beyond Single Targets: A Review of Triazole-Thiazole Hybrids in Modern Drug Design

Triazole-thiazole hybrids represent highly privileged scaffolds in medicinal chemistry, characterized by exceptional structural versatility and a broad spectrum of pharmacological profiles, including anticancer, antimicrobial, antidiabetic, and anti-inflammatory activities. This review provides a critical overview of recent advancements in the synthesis, structure–activity relationships (SAR), and therapeutic applications of these dual-heterocyclic frameworks. We highlight strategic methodologies for integrating triazole and thiazole cores with complementary pharmacophores to enhance potency, optimize pharmacokinetic profiles, and circumvent multi-drug resistance. Furthermore, current optimization bottlenecks and emerging computational paradigms are systematically evaluated. Ultimately, this survey delineates key design principles for leveraging the modularity of triazole-thiazole scaffolds in the development of next-generation, multi-target directed ligands (MTDLs) against complex etiologies.
