Resveratrol - Solutions

Resveratrol is a natural compound found in grape seeds and skin and in red wine. Used previously against MERS-CoV infection (Lin et al., 2017).

Lin SC, Ho CT, Chuo WH, Li S, Wang TT, Lin CC - "Effective inhibition of MERS-CoV infection by resveratrol" BMC Infect Dis 17(1):144 (2017) doi: 10.1186/s12879-017-2253-8. PMID: 28193191; PMCID: PMC5307780.

Now suggested for treatment in COVID-19.

"Taken together, these evidences suggest that CoV-induced down-regulation of ACE2 activates RAS with collateral damage to organs, such as lungs, in the course of SARS-related pneumonia. Then, putative therapeutic measures aimed at increasing ACE2 levels on respiratory epithelial cells should be taken into serious consideration. Quite interestingly, over the past few years, three key papers have demonstrated the ability of a polyphenol, resveratrol (RES), to experimentally deactivate the RAS system in maternal and post-weaning high fat diet, arterial ageing and high fat diet, respectively [42-44]. In all these experimental models, RES led to an increase of ACE2 with reduction of organ damage."

Previous studies have shown that resveratrol exerted antiviral activities by blocking the NF-κB pathway (Zhang et al., 2015).

"Resveratrol, the naturally occurring polyphenolic compound characterized by anti-oxidative, anti-inflammatory and apoptotic properties, appears to contribute substantially to cardioprotection and cancer-prevention. In addition, resveratrol is believed to regulate several biological processes, mainly metabolism and aging, by modulating the mammalian silent information regulator 1 (SIRT1) of the sirtuin family. Resveratrol may arrest, among various tumors, cell growth in both papillary and follicular thyroid cancer by activation of the mitogen-activated protein kinase (MAPK) signal transduction pathway as well as increase of p53 and its phosphorylation. Finally, resveratrol also influences thyroid function by enhancing iodide trapping and, by increasing TSH secretion via activation of sirtuins and the phosphatidylinositol- 4-phosphate 5 kinase γ (PIP5Kγ) pathway, positively affects metabolism."

The NF-KappaB [NF-κB] pathway is downstream from Gq/11 activation.
