Pyran-Fused Analogues and Their Potential Applications

Heterocyclic compounds represent one of the most prominent classes of currently used pharmaceuticals. Among these, the pyran ring has attracted significant research interest due to its broad spectrum of pharmacological properties. Notably, molecules such as benzopyrans, chromones, flavonoids, coumarins, xanthones, and naphthoquinones—each featuring a pyran core—exhibit diverse biological activities. This structural motif is widely present in both naturally occurring and synthetically derived compounds. The remarkable medicinal properties of various natural products, including pyrans and benzopyrans, have captivated the scientific community. This report provides a concise overview of the synthesis, characterization, and therapeutic applications of pyran-fused analogues.
