Insights

Reactive oxygen species (ROS) are crucial for cell signaling but can cause diseases like cancer when imbalanced. This review explores small-molecule inhibitors targeting ROS production for therapeutic development.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Pharmacology

Background:

  • Reactive oxygen species (ROS) are vital signaling molecules regulating cellular processes like proliferation and apoptosis.
  • Maintaining redox homeostasis, the balance of ROS production and neutralization, is critical for cell health.
  • Elevated ROS levels are implicated in major diseases, including cancer, neurodegeneration, and cardiovascular conditions.

Purpose of the Study:

  • To outline major cellular sources of ROS production.
  • To comprehensively review small-molecule inhibitors targeting ROS production.
  • To critically assess the therapeutic potential and future research directions for ROS inhibitors.

Main Methods:

  • Literature review of major cellular ROS production pathways.
  • Systematic evaluation of small-molecule ROS inhibitors.
  • Analysis of inhibitor potency, mechanism of action, off-target effects, and clinical/preclinical status.

Main Results:

  • Identification of key cellular sources of ROS.
  • Compilation and critical assessment of various ROS-targeting small-molecule inhibitors.
  • Evaluation of the therapeutic landscape and challenges in developing ROS inhibitors.

Conclusions:

  • Targeting ROS production with small molecules presents a promising therapeutic strategy for diseases linked to oxidative stress.

The Electron Transport Chain01:30

The Electron Transport Chain

The electron transport chain or oxidative phosphorylation is an exothermic process in which free energy released during electron transfer reactions is coupled to ATP synthesis. This process is a significant source of energy in aerobic cells, and therefore inhibitors of the electron transport chain can be detrimental to the cell's metabolic processes.
Inhibitors of the electron transport chain

Radical Autoxidation01:20

Radical Autoxidation

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Oxidation of Phenols to Quinones01:17

Oxidation of Phenols to Quinones

In the presence of oxidizing agents, phenols are oxidized to quinones. Quinones can be easily reduced back to phenols using mild reducing agents. The electron-donating hydroxyl group enhances the reactivity of the aromatic ring, enabling oxidation of the ring even in the absence of an α hydrogen.
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...

Peroxisomes01:24

Peroxisomes

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...
