Insights

Polyphenols show anticancer effects by targeting specific protein kinases. This review highlights polyphenols as potential agents against aggressive and metastasizing cancers by analyzing their structure-activity relationships.

Area of Science:

  • Oncology
  • Pharmacology
  • Natural Products Chemistry

Background:

  • Over 1100 publications document polyphenol anticancer activities.
  • Polyphenols exhibit diverse anticancer effects, including anti-oxidative and pro-apoptotic properties.
  • Targeting protein kinases is a key strategy in modern cancer therapy.

Purpose of the Study:

  • To comprehensively review anticancer polyphenols targeting specific kinases.
  • To analyze polyphenol structure-activity relationships in kinase inhibition.
  • To identify potential polyphenol-based antitumor agents for aggressive cancers.

Main Methods:

  • Literature search of PubMed database (July 2009) using keywords: "polyphenols - cancer - review" and "polyphenols - cancer - kinases".
  • Analysis of existing review articles on polyphenol anti-kinase activity.
  • In-depth examination of structure-activity relationships for kinase targeting.

Main Results:

  • Over 320 review articles and 130 research articles on polyphenols and cancer were identified.
  • Curcumin and epigallocatechin 3-gallate (EGCG) are prominent examples of kinase-targeting polyphenols.
  • Significant research exists on polyphenol kinase inhibition, with a recent surge in publications.

Conclusions:

  • Polyphenols demonstrate significant potential as anticancer agents through specific kinase targeting.
  • Understanding structure-activity relationships is crucial for developing effective polyphenol-based therapies.
  • Polyphenols may offer novel therapeutic strategies against aggressive and metastatic cancers.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
