Since the beginning of the pandemic, researchers worldwide have been looking for ways to treat COVID-19.

And while the COVID-19 vaccines represent the best measure to prevent the disease, therapies for those who do get infected remain in short supply.

In a recent study published in the Proceedings of the National Academy of Science, researchers found several drug contenders already in use for other purposes—including one dietary supplement—that have been shown to block or reduce SARS-CoV2 infection in cells.

The study is from the University of Michigan. One author is Jonathan Sexton, Ph.D.

In the study, the team used artificial intelligence-powered image analysis of human cell lines during infection with the novel coronavirus.

The cells were treated with more than 1,400 individual FDA-approved drugs and compounds, either before or after viral infection, and screened, resulting in 17 potential hits.

Ten of those hits were newly recognized, with seven identified in previous drug repurposing studies, including remdesivir, which is one of the few FDA-approved therapies for COVID-19 in hospitalized patients.

The team validated the 17 candidate compounds in several types of cells, including stem-cell-derived human lung cells in an effort to mimic SARS-CoV2 infection of the respiratory tract.

Nine showed anti-viral activity at reasonable doses, including lactoferrin, a protein found in human breastmilk that is also available over the counter as a dietary supplement derived from cow’s milk.

The team is now soon launching clinical trials of the compound to examine its ability to reduce viral loads and inflammation in patients with SARS-CoV2 infection.

The trials are adding to the list of ongoing studies of promising repurposed drugs.

The team noted that over the course of the pandemic, other drug repurposing studies have identified different compounds with potential efficacy against SARS-CoV2.

Remarkably, the team also identified a class of compounds called MEK-inhibitors, typically prescribed to treat cancer, that appears to worsen SARS-CoV2 infection.

If you care about COVID drugs, please read studies about this existing drug could inhibit COVID-19 virus and findings of aspirin and other common anti-inflammatory drugs could help prevent COVID-19 deaths.

For more information about COVID and your health, please see recent studies about early use of this blood thinner drug may reduce COVID-19 death and results showing that this drug may prevent respiratory and heart damage in people with COVID-19.

So wonderful to think that they have been studying and messing with covid for years but didn't make sure to know what would treat it prior to this happening? And were fast on that vaccine. Something doesn't add up. So tired of the games.

If you can't come to the realization that this was all planned by the deep state and funded by Bill Gates and Fauci, you'll never be awake.

Cherie H

how is Remdesivir approved when it killed 52% of the people it was used on to treat Ebola? Oh wait these companies pay for the testing and that's Fuaci's drug he can profit from And his wife is head of the company that does the testing so there is that.
