32313880 Thus, as alternative potentially more direct “broad-spectrum” COVID-19 therapeutics, several natural and synthetic PAK1-blockers such as propolis, melatonin, ciclesonide, hydroxy chloroquine (HQ), ivermection, and ketorolac, which are readily available in the market, are introduced here.
32314850 Viral, or preexistent, suppression of pineal melatonin disinhibits neutrophil attraction, thereby contributing to an initial “cytokine storm”, as well as the regulation of other immune cells. […] Melatonin induces the circadian gene, Bmal1, which disinhibits the pyruvate dehydrogenase complex (PDC), countering viral inhibition of Bmal1/PDC. […] Pineal melatonin suppression attenuates this, preventing the circadian “resetting” of mitochondrial metabolism. […] Consequently, pineal melatonin regulates mitochondrial melatonin and immune cell phenotype.
32347747 Children don’t suffer from COVID-19 as much as their grandparents and have a much higher melatonin level. […] Bats are nocturnal animals possessing high levels of melatonin, which may contribute to their high anti-viral resistance.

32597503 Melatonin is a chronobiotic hormone, which can regulate human diseases like cancer, atherosclerosis, respiratory disorders, and microbial infections by regulating redox system. […] Melatonin exhibits innate immunomodulation by communicating with immune system and influencing neutrophils to fight infections and inflammation. […] Therefore, we hypothesized that redox modulators like melatonin can protect neutrophil health and functions under GSH and GR activity-deficient conditions. […] We demonstrate the dual role of melatonin, wherein it protects neutrophils from oxidative stress-induced apoptosis by reducing ROS generation; in contrast, it restores neutrophil functions like phagocytosis, degranulation, and NETosis in GSH and GR activity-deficient neutrophils by regulating ROS levels both in vitro and in vivo. […] Melatonin mitigates LPS-induced neutrophil dysfunctions by rejuvenating GSH redox system, specifically GR activity by acting as a parallel redox system. […] Our results indicate that melatonin could be a potential auxiliary therapy to treat immune dysfunction and microbial infections, including virus, under chronic disease conditions by restoring neutrophil functions. […] Further, melatonin could be a promising immune system booster to fight unprecedented pandemics like the current COVID-19. […] However, further studies are indispensable to address the clinical usage of melatonin.

[…] Interestingly, one of the most promising hits in our docking study was melatonin. […] Consequently, melatonin can have response potential in early stages for its possible effects on ACE-2 and Mpro, although it is also promising in more severe stages of the disease for its action against hyper-inflammation.
32992875 Melatonin is a molecule that can enhance the host’s tolerance against pathogen invasions. […] Due to its antioxidant, anti-inflammatory, and immunoregulatory activities, melatonin has the capacity to reduce the severity and mortality of deadly virus infections including COVID-19. […] Melatonin is synthesized and functions in mitochondria, which play a critical role in viral infections. […] Not surprisingly, melatonin synthesis can become a target of viral strategies that manipulate the mitochondrial status. […] For example, a viral infection can switch energy metabolism from respiration to widely anaerobic glycolysis even if plenty of oxygen is available (the Warburg effect) when the host cell cannot generate acetyl-coenzyme A, a metabolite required for melatonin biosynthesis. […] Under some conditions, including aging, gender, predisposed health conditions, already compromised mitochondria, when exposed to further viral challenges, lose their capacity for producing sufficient amounts of melatonin. […] Thus, the maintenance of mitochondrial function by melatonin supplementation can be expected to generate beneficial effects on the outcome of viral infectious diseases, particularly COVID-19.
