Potential therapeutic effects of Resveratrol against SARS-CoV-2.

Novel Coronavirus COVID-19 or Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as well as Severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), are human pathogens. Current pandemics of SARS-CoV-2 represents a major health problem worldwide, with over four million cases and more than 300,000 deaths in the world. Development of effective therapy thus became an emergency. This report aims to highlight Resveratrol as possible therapeutic candidate in SARS-CoV-2 infection. The antiviral efficacy of Resveratrol was demonstrated for several viruses, including coronavirus. Resveratrol was shown to mitigate the major pathways involved in the pathogenesis of SARS-CoV-2, including regulation of the renin-angiotensin system (RAS) and expression of angiotensin-converting enzyme 2 (ACE2), stimulation of immune system and downregulation of pro-inflammatory cytokines release. It was also reported to promote SIRT1 and p53 signaling pathways and increase cytotoxic T lymphocytes (CTLs) and natural killer (NK) immune cells. In addition, Resveratrol was demonstrated to be a stimulator of fetal hemoglobin and a potent antioxidant, by trapping reactive oxygen species (ROS). According to these reports, Resveratrol could be proposed as potential therapeutics in the treatment of SARS-CoV-2.
