A Comprehensive Appraisal of Chalcones and Their Heterocyclic Analogs as Antimicrobial Agents

Owing to the growing demand for compelling antimicrobial agents, chalcones and their heterocyclic derivatives have engrossed prodigious attention of medicinal chemists as an effective clinical template for the synthesis of such agents on account of their structural diversity and molecular flexibility. Chalcones are considered as a fortunate scaffold in the field of both synthetic as well as natural product chemistry. They are reflected as a remarkable section of logically occurring pharmacophores that possess a comprehensive scale of biological activities, such as anti-cancer, anti-malarial, anti-viral and anti-inflammatory, rendering them with a high degree of assortment and noble therapeutic profile. They act as a crucial intermediate for the synthesis of novel heterocyclic skeletons holding biodynamic behavior. This review emphasizes on different aspects of chalcones including their natural sources, recent synthetic methodologies and evaluation of their anti-microbial potential. It is expected as a persuasive compilation on chalcones that may benefit the experts to design potent and less toxic chalcone referents as medicinal agents.
