Scientists find the key to curing COVID-19
Developing new drugs to treat diseases can take years or decades—a time that we do not have when it comes to treating patients with COVID-19.
In a recent study published in PNAS, researchers found another way to discover treatments for the disease: parsing through drugs that already exist.
And, after considering all the drugs that are currently available to patients to treat myriad other ailments, they identified four strong contenders to treat COVID-19.
The study is from Northeastern University. One author is Deisy Morselli Gysi.
Looking at existing drugs is a much faster and cheaper approach than developing something new because the drugs already exist and they’re generally already approved by regulatory authorities, so can be put straight into clinical trials to test whether they can work to beat the new disease.
But doing that for every individual drug on the market isn’t very efficient. There are thousands.
In the study, the team used a network medicine approach to scan a database of existing drugs for characteristics that might make them good at treating COVID-19.
They examined the network of cellular interactions that occur as the virus that causes COVID-19 establishes itself in the human body and used that information to figure out what existing drugs might disrupt that process.
Using artificial intelligence and other network science tools, the researchers ranked around 7,000 drugs and selected 918 for further screening to determine if they would be viable treatments for COVID-19 in the real world.
In the laboratory, 918 drugs were tested to treat COVID-19 in green monkey cells first. Then, the best-performing ones out of the top 200 were tested in human cells.
Of those drugs screened, six prevented the virus from reproducing (and thus killed it off) without killing the human cells.
Four of those six drugs could feasibly be repurposed and potentially deployed in COVID-19 patients, the team says.
