Current Developments in the Pyran-Based Analogues as Anticancer Agents.

Heterocyclic compounds offer an enormous area for new lead molecules for drug discovery. Till today, efforts are being continuously made to find appropriate treatment for the management of the deadly disease of cancer. Amongst the large number of heterocycles that are found in nature, heterocycles having oxygen obtained noteworthy attention due to their distinctive and pharmacological activities.'Pyran' is one of the most significant non-aromatic, sixmembered ring composed of one oxygen atom and five carbon atoms. It is considered a privileged structure since pyran and its related derivatives exhibit a wide spectrum of biological activities. Pyran derivatives are found to have excellent anti-cancer properties against various types of cancer. The present review focussed on the current advances in different types of pyran-based derivatives as anti-cancer agents. Various in vitro (cell based testing), in vivo (animal based testing) models as well as molecular docking along with results are also covered. A subsection describing briefly natural pyran containing anticancer compounds is also incorporated in the review.
