Insights

New small molecules can activate p53 and inhibit nuclear factor-kappaB (NF-kappaB) simultaneously, promoting cancer cell apoptosis. This review explores dual-acting drugs for cancer therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Discovery

Background:

  • The p53 and nuclear factor-kappaB (NF-kappaB) pathways are critical in human cancer.
  • Cancer often involves p53 inactivation and NF-kappaB hyperactivation.
  • Activating p53 and inhibiting NF-kappaB induces apoptosis.

Purpose of the Study:

  • To review small molecules with dual activity on p53 and NF-kappaB pathways.
  • To explore the principles and mechanisms of these dual-acting compounds.
  • To suggest future directions for developing dual-acting cancer drugs.

Main Methods:

  • Literature review of existing research on p53 and NF-kappaB pathways.
  • Analysis of small molecules exhibiting dual activity.
  • Discussion of proposed mechanisms for dual action.

Main Results:

  • Certain small molecules possess the ability to simultaneously activate p53 and inhibit NF-kappaB.
  • These dual-acting molecules show potential for promoting cancer cell apoptosis.
  • The review identifies candidate molecules and discusses their therapeutic implications.

Conclusions:

  • Simultaneous modulation of p53 and NF-kappaB represents a promising therapeutic strategy for cancer.
  • Further development of dual-acting small molecules could lead to novel cancer treatments.
  • Targeting both pathways offers a concerted approach to cancer therapy.

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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...
