REVIEW ON SUBSTITUTED 1,2,4-TRIAZOLES AS POTENT ANTI-FUNGAL,ANTI-CANCER AND ANTI-TUBERCULAR AGENTS

Triazole derivatives are an important class of nitrogen-containing heterocyclic compounds widely studied in medicinal chemistry. These compounds possess a five-membered ring structure containing three nitrogen atoms, which contributes to their remarkable chemical stability and diverse biological activities. Due to their versatile structural properties, triazole derivatives have gained considerable attention in pharmaceutical research and drug development. Many triazole-based compounds exhibit significant pharmacological activities such as antifungal, antibacterial, anticancer, anti-tubercular, anti-inflammatory, and antiviral effects. Several clinically useful drugs, including Fluconazole, Itraconazole, and Voriconazole, contain the triazole ring as a key structural component responsible for their therapeutic action. The presence of nitrogen atoms in the triazole ring enhances their ability to interact with biological targets, improving potency and selectivity. Because of these advantages, triazole scaffolds are frequently used as core structures for designing new bioactive molecules. This review highlights the chemical characteristics of triazole derivatives and summarizes their important pharmacological activities and therapeutic significance in modern medicinal chemistry research.
