**Abstract**

Pyridine is a heterocyclic molecule with a nitrogen atom that is often found in nature. As a prosthetic group taking part in redox processes in the biological system, it plays an important function in many enzymes of the living system. Pyridine is an important pharmacophore, a privileged scaffold, and a superior heterocyclic system in drug development, with various applications in anticancer research because of its ability to work on significant receptors. Typically, it is the core of several currently available medicines. In the fight against cancer, many pyridine derivatives have been shown to inhibit kinases, androgen receptors, tubulin polymerization, topoisomerase enzyme, human carbonic anhydrase, and several other targets. Researchers are now concentrating on developing pyridine novel entities with other moieties for cancer therapy. This section presents pyridine derivative synthesis and biological expansions, as well as their target receptor sites.
