Abstract: A review concerning the synthesis and pharmacological properties of pyrazoles
obtained from Chalcone described in the literature over the last 5 years (2016-2020) was presented
and discussed. Among the synthetic approaches for pyrazoles described so far, the
cyclization and acetylation method of α,β-unsaturated chalcones, and substituted hydrazine
were selected and analyzed. 105 pyrazole derivatives (3-107) were evaluated as well as their
pharmacological activities, namely, antineoplastic, anti-inflammatory, antioxidant, antibacterial,
antifungal, antimycobacterial, antiplasmodial, Alzheimer's disease, enzymes inhibition
(like acetylcholinesterase, carbonic anhydrase, and malonyl CoA decarboxylase), anticonvulsant,
among others. Pyrazolic compounds are widely used in the design of the new drug with
a wide spectrum of pharmacological approaches. Therefore, it is relevant to research the synthetic
methods and therapeutic properties of different pyrazole derivatives.
