Synthesis and Antitumor Activities of Resveratrol Derivatives on Cervical Cancer Hela Cells

A Review on the Mechanism and Structure-activity Relationship of Resveratrol Heteroaryl Analogues

Resveratrol is one of the most interesting naturally-occurring nonflavonoid phenolic compounds with various biological activities, such as anticancer, neuroprotection, antibacterial, and anti-inflammatory. However, there is no clinical usage of resveratrol due to either its poor activity or poor pharmacokinetic properties. Heteroarenes-modified resveratrol is one pathway to improve its biological activities and bioavailability, and form more modification sites. In this review, we present the progress of heteroaryl analogues of resveratrol with promising biological activities in the latest five years, ranging from the synthesis to the structure-activity relationship and mechanism of actions. Finally, introducing heteroarenes into resveratrol is an effective strategy, which focuses on the selectivity of structure-activity relationship in vivo.

Resveratrol - A comprehensive review of recent advances in anticancer drug design and development

Resveratrol is a natural polyphenolic stilbene isolated from various plants, foods and beverages with a broad spectrum of biological and pharmacological properties through modulating diverse targets and signaling pathways. Particularly, it has attracted a great deal of attention as a promising and multitarget anticancer agent due to its potential use in chemoprevention and chemotherapy of various tumors. However, unfavorable pharmacokinetics/pharmacodynamics profile such as poor bioavailability restricted its applications. Therefore, medicinal chemists have synthesized a lot of novel derivatives and analogues of resveratrol using different modification strategies to overcome these limitations and improve anticancer efficacy. Herein, we reviewed the design, synthesis, structure-activity relationship and mechanism of the most potent and privileged resveratrol-based compounds that showed promising anticancer activities in the last five years. We classified these compounds into the ten different categories based on their chemical structure similarities.

Design, synthesis and antibreast cancer MCF-7 cells biological evaluation of heterocyclic analogs of resveratrol

A new series of resveratrol heterocyclic analogs (4a-m) were designed and synthesized, and their inhibitiory effects on MCF-7 cells were evaluated to investigate structure-activity relationship. The effects of these analogs on human breast cancer MCF-7 cells were also determined. Results showed that MCF-7 cells could be inhibited more potently by these analogs than by resveratrol (IC₅₀ = 80.0 μM). Among the analogs, compounds 4c, 4e, and 4k showed a significantly higher activity (IC₅₀ = 42.7, 48.1, and 43.4 μM) than resveratrol. Furthermore, the derivatives without additional heterocyclic structure in the 4'-OH position exhibited a more potent activity than that with addition heterocyclic structure. In addition, docking simulation was performed to adequately position compound 4c in a human F₁-ATPase active site to determine a probable binding model. These heterocyclic analogs could be effective candidates for the chemoprevention of human breast cancer.

Resveratrol derivatives: an updated patent review (2012-2015)

INTRODUCTION

Resveratrol is a well-studied natural small molecule that possesses diverse bioactivities. Chemical derivation based on the resveratrol scaffold is of great importance to overcome the drawbacks of resveratrol and to improve its therapeutic potential. Continuous efforts have been established to develop resveratrol derivatives that target different therapeutic applications. Areas covered: This review covers patents published from 2012 to 2015. All resveratrol derivatives discussed are classified based on its derivation strategy as simple derivatives, conjugated derivatives and miscellaneous derivatives. Their therapeutic related activities are reviewed and discussed. Expert opinion: Chemical derivation is an effective strategy to enhance the benefits of resveratrol and ameliorate its disadvantages. Recent studies on resveratrol derivatives have made great progress in the treatment of cancer and neurodegenerative diseases to name a few, demonstrating improved activity compared with resveratrol. Notably, its bioavailability was also improved in some cases. However, the 'next generation' of resveratrol derivatives still requires the development of new strategies and techniques.
