Synthesis and Pharmacological Activity of 4', 4''-bit modified, Curcumin Derivatives

Background: Curcumin is a polyphenol compound extracted from plant turmeric with high pharmacological activities. The clinical application of curcumin is limited due to the shortcomings of poor water solubility, instability, and low bioavailability. Objective: Modifying the 4', 4''-bit of curcumin is an effective strategy to improve the pharmacological activity of curcumin. Conclusion: In this review, we focused on the strategy of synthesis, medicinal properties, and structurefunction relationship of 4', 4''-bit modified, curcumin derivatives.
