HETEROCYCLIC COMPOUNDS IN DRUG DISCOVERY: RECENT DEVELOPMENTS AND APPLICATIONS

Heterocyclic compounds constitute a fundamental class of chemical entities extensively utilized in modern drug discovery due to
their remarkable structural diversity and biological versatility. These compounds, characterized by the presence of at least one
heteroatom such as nitrogen, oxygen, or sulfur within a cyclic framework, exhibit a wide range of pharmacological activities
including antimicrobial, anticancer, anti-inflammatory, antiviral, and central nervous system effects. Recent advancements in
synthetic methodologies, computational drug design, and high-throughput screening have significantly accelerated the
identification and optimization of heterocyclic scaffolds for therapeutic applications. Furthermore, the integration of structure
activity relationship (SAR) studies and molecular modeling has enhanced the rational design of potent and selective drug
candidates. Despite their advantages, challenges such as toxicity, metabolic instability, and synthetic complexity remain critical
considerations. This review highlights recent developments, therapeutic applications, and future perspectives of heterocyclic
compounds in drug discovery, emphasizing their indispensable role in pharmaceutical innovation.
