Benzopyrans

Benzopyrans (also called chromenes), bicyclic heterocyclic systems consisting of a benzene ring fused to a heterocyclic pyran ring, constitute a privileged structure in medicinal chemistry. Benzopyran derivatives (chromones and flavones) are potentially useful anti-inflammatory agents due to their ability to inhibit protein kinase dependant signal transduction pathways. Furthermore, some natural benzopyran derivatives showed inhibitory activity of prostaglandin E2 (PGE2) production. Benzopyran derivatives are also an attractive template for the identification of potential anticancer agents.
