Antioxidant Development
Antioxidants are defined as compounds or therapies designed to treat or manage rare neurologic conditions where oxidative stress is a predominant underlying pathological feature. At Protheragen, we focus on the development of new therapeutic antioxidants and the creation of exact animal models to expedite the preclinical evaluation of drug candidates. With us, you can rest assured that your research is receiving the best and most pertinent assistance, which in turn, speeds up your medication development timeline.
Introduction to Antioxidants for Rare Neurological Diseases
Chronic oxidative stress marks the pathological hallmarks of most neurological diseases and is defined by the overproduction of reactive oxygen species (ROS) and reactive nitrogen species (RNS), which inflict injury to lipids, proteins, and DNA, as well as impair mitochondrial function. Antioxidants can neutralize neurotoxic ROS directly or tune up endogenous defense mechanisms, which in turn provides neuroprotection, reduces neuroinflammation, and slows disease progression. They are essential therapeutic agents to cope with chronic oxidative stress in neurological disorders.

Mechanisms of Action of Antioxidants
Combating neurological oxidative stress, antioxidants work through multiple mechanisms: direct free radical scavenging, enhancement of endogenous defenses, ROS-producing enzyme inhibition, mitochondrial protection, and chelation of redox-active metals. The neuroprotective properties of antioxidants in oxidative stress are achieved collectively through the different pathways noted above.
