Abstract

Pyridazinones and pyrrolones are important building blocks for some important drugs such as the naturally occurring antibacterial pyrrolone, althiomycin; the cardiotonic pyridazinones, pimobendan and levosimendan and the analgesic anti-inflammatory, emorfozan. Therefore, researchers all over the world paid attention to prepare various pyridazinones and pyrroolones derivatives. The variability in the biological response and ease of preparation from the corresponding furanones attracted attention of researchers to explore these two nuclei in the design and synthesis of different analogues with potential biological actvities. This review article focuses on different biological activities, structure activity relationship and mechanism of action of pyridazinones and pyrrolones derivatives.
