Synthesis and Biological Activity of 2-pyridone Derivatives: A Mini Review

pyridone nucleus is an important scaffold present in various compounds with diverse pharmacological activity. Among the reported 2-pyridone analogs, the majority of the compounds either have a substituted ring system or a fused ring system. Till now, several derivatives have been reported by different researchers for their antimicrobial activity, anticancer activity, antiviral activity, antioxidant activity, anti-hepatitis virus activity, and anti-allodynia and anti-obesity activities. In this review, we have attempted to compile synthetic methods of 2-pyridone ring by ring cyclization along with pharmacological aspects related to various synthesized derivatives of the 2-pyridone nucleus.
