Recent Updates in Curcumin Pyrazole and Isoxazole Derivatives: Synthesis and Biological Application.

Abstract

Curcumin is an admired, plant-derived compound that has been extensively investigated for diverse range of biological activities, but the use of this polyphenol is limited due to its instability. Chemical modifications in curcumin are reported to seize this limitation; such efforts are intensively performed to discover molecules with similar but improved stability and better properties. Focal points of these reviews are synthesis of stable pyrazole and isoxazole analogs of curcumin and application in various biological systems. This review aims to emphasize the latest evidence of curcumin pyrazole analogs as a privileged scaffold in medicinal chemistry. Manifold features of curcumin pyrazole analogs will be summarized herein, including the synthesis of novel curcumin pyrazole analogs and the evaluation of their biological properties. This review is expected to be a complete, trustworthy and critical review of the curcumin pyrazole analogs template to the medicinal chemistry community.
