The Effects of Antioxidant Approved Drugs and Under Investigation Compounds with Potential of Improving Sleep Disorders and their Associated Comorbidities associated with Oxidative Stress and Inflammation

Abstract: Sleep disorders and the resultant sleep deprivation (SD) are very common nowadays, resulting in depressed mood, poor memory and concentration, and various important changes in health, performance and safety. They may provoke further impairment of the cell lining of the blood vessels, as acting as a risk factor for cardiovascular disease (CVD) onset and progression. SD may lead to low neuronal regaining and plasticity, drastically affecting brain function. Thus, SD is a known risk factor for mental, behavioral and developmental disorders. Due to the inflammatory and oxidative stressful nature of SD, immune response modulation and antioxidants could be another therapeutic approach, apart from the already known symptomatic treatment with sedatives. Additionally, many drugs approved for other indications and under investigation, have been revisited due to their wide array of pharmacological activities. This review summarizes the main aspects of SD pathology and SD interrelated comorbidities and presents direct and indirect antioxidant molecules and drugs with multi-targeting potential that could assist in the prevention or management of these factors. A number of research groups have investigated well-known antioxidant compounds with multi-targeting cores, combining structural characteristics with properties including antiinflammatory, metal chelatory, gene transcription and immune modulatory that may add towards the effective SD and its associated comorbidities treatment.
