Heterocyclic compounds are of fundamental importance to biological process and are wide spread of natural products. Heterocyclic compounds are finding an increasing use as intermediates in organic synthesis. Heterocyclic compounds are organic compounds that contain a ring structure containing atom in addition to carbon, as part of the ring. Many of the heterocyclic ring systems are of fundamental importance to living systems. Naphthyridine is the name commonly given to the fused-ring system resulting from the fusion of two pyridine rings through two adjacent carbon atoms, each ring thus containing only one nitrogen atom. Many heterocyclic have important pharmaceutical properties and have a wide range of applications: they are predominant among the types of compounds used as pharmaceuticals, as agro chemicals and as veterinary products. The 1, 8-Naphthyridine derivatives are reported to possess a wide spectrum of biological activities such as antibacterial, antimalarial, anti-inflammatory, antitumor, antiviral, and other useful biological and chemical applications.
