Natural products as models for the conception of new active products: Benzopyran, a privileged structure

Abstract

Natural products are a useful source for the discovery of new bioactive products. The role of defense played by natural products in the living organisms that synthesize them most probably explains their particular interest in the discovery of antifungal, antibacterial, antiparasitic, and anticancer drugs implying novel mechanisms of action. In those therapeutic fields, most of new approved drugs are natural products, natural products derivatives, or synthetic mimics, which incorporate a pharmacophore present in a natural product.
