Chalcones are α, β unsaturated aromatic ketones having enone moiety and exhibit a wide array of pharmaceutical and biological activities. Chalcones possess a wide range of biological activities such as anticancer, antituberculosis, antidiabetic, antioxidant, anti‐inflammatory, antimicrobial, and antimalarial. Nitrogen‐containing heterocyclic compounds are an extremely important class of organic compounds with a broad spectrum of pharmaceutical activities. Pyrazolines are N‐ heterocyclic compounds that exhibit a wide range of pharmaceutical activities and are synthesized from chalcone with enhanced biological activity. The present study summarizes the chemistry of various chalcone‐based pyrazolines and their derivatives with the available data till 2021.
