Reactive oxygen and nitrogen species and inflammatory proteins (RONS and inflammatory proteins)

Reactive oxygen and nitrogen species (RONS) and inflammatory proteins represent a broad and heterogeneous group of molecules that mediate cellular signaling and the immune response. RONS, such as superoxide and nitric oxide, are highly reactive molecules that can cause oxidative and nitrosative stress, leading to damage of DNA, proteins, and lipids (Source: NIH). Inflammatory proteins, including cytokines like TNF-alpha and enzymes like COX-2, are critical drivers of the inflammatory cascade in response to tissue injury or pathogens (Source: StatPearls). While these molecules are essential for normal physiological processes like pathogen defense and cell signaling, their chronic overproduction is a hallmark of diseases such as rheumatoid arthritis, atherosclerosis, and neurodegeneration (Source: PubMed). Therapeutic strategies often involve the use of antioxidants to neutralize RONS or monoclonal antibodies and small molecules to inhibit specific inflammatory proteins (Source: PubChem). However, because this category encompasses a vast network of molecules rather than a single discrete target, it is considered a biological pathway or process. This complexity presents significant challenges for drug specificity, as broad inhibition can interfere with necessary physiological functions.

Drugs targeting these entities work by scavenging free radicals, inhibiting enzymes that produce reactive species (such as NADPH oxidase or COX-2), or neutralizing specific inflammatory proteins like cytokines to prevent downstream signaling cascades.
