Leishmaniases are endemic diseases in tropical and sub-tropical regions of the world and are considered by the World Health Organization (WHO) to be among the six most important neglected tropical diseases. The current therapeutic arsenal against the disease is associated with a series of chemotherapeutic setbacks. However, since the early 1990s, naturally occurring chalcones with promising antileishmanial effects have been reported, and several other synthetic chalcones and chalcone-hybrid molecules have been confirmed to possess potent activity against various Leishmania species. This paper is a comprehensive review covering the antileishmanial activity of 34 naturally occurring chalcones, 224 synthetic/semisynthetic chalcones and 54 chalcone-hybrid molecules. Several chalcones in the synthetic/semisynthetic category had IC50 values < 5 mu M, with very good selectivity against parasites, and the structure-activity relationships as well as the proposed mechanism of action are discussed. We identified knowledge-gaps with the hope of providing future direction for the discovery of novel antileishmanial drugs from chalcones.
