Diversely Functionalized Pyridine Ring-Fused Heterocycles and Their Anticancer Properties

Among N-containing heterocycles, pyridine occupies a prominent position due to its presence in nature. Many enzymes in living systems, which are involved in redox reactions, contain pyridine moiety. In addition, its importance in medicinal chemistry and its presence in drugs are well documented. Several pyridine containing compounds are well-known as tubulin polymerization inhibitors and are found to bind with androgen receptors, kinases, carbonic anhydrase and topoisomerase. In recent years, researching have been modifying pyridine containing entities to treat cancer. This review sheds light on recent developments in anticancer studies of pyridine ring-fused heterocyclic compounds.
