Oxidative stress and inflammatory mediators

Oxidative stress and inflammatory mediators represent a broad category of physiological processes and signaling molecules rather than a single discrete therapeutic target. Oxidative stress is characterized by an imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant defense systems, leading to oxidative damage of lipids, proteins, and DNA (NIH, 2022). Inflammatory mediators, including cytokines (e.g., TNF-alpha, IL-6), chemokines, and lipid mediators like prostaglandins, are soluble agents that coordinate the immune response to injury or infection (StatPearls, 2023). These two systems are fundamentally linked; oxidative stress can activate pro-inflammatory transcription factors such as NF-kappaB, while chronic inflammation induces further ROS production by immune cells, creating a self-amplifying pathological cycle (Reuter et al., 2010). Because this term encompasses a vast array of distinct molecular targets across numerous disease states—including cardiovascular disease, neurodegeneration, and cancer—it is considered a therapeutic area or mechanism of action rather than a specific protein target. Drug development in this space typically focuses on specific components, such as monoclonal antibodies against cytokines or small molecules that activate the Nrf2 antioxidant pathway.
