Synthetic Routes and Biological Activities of Chromone Scaffolds: An Overview

Abstract

The central backbones of natural assets and therapeutic medications are chromone and flavone. Utilizing such preferred chalcone analogs in drug research has shown a successful blueprint, yielding new hits/leads and fast optimization procedures. Chromone can create novel molecules with pharmacological promise, particularly in neurological, inflammatory, infectious diseases, cancer and diabetes. The current perspective focuses mainly on flavones and flavonoids of biological significance, such as chromon-4-one analogs, both synthetic and natural sources. Furthermore, because drug repurposing is now a popular drug discovery strategy, current chromone-based medication repurposing research is discussed. As well the methods utilized to synthesize chromones and their derivatives are described in detail in this review. Since it’s uses in so many pharmacologically active substances, the stiff bicyclic chalcone fraction has been described as a preferred scaffold in drug development, with few instances as therapeutic agents. Due to their photochemical characteristics, chromone analogs are also utilized as scaffolds for creating bioactive molecules and their application in drug development, such as the production of fluorescent probes.
