A drug used to treat coronavirus infections in cats could soon be used to treat Covid-19 in humans, after researchers demonstrated that the drug works as opposed to SARS-CoV2 coronavirus in laboratory experiments.
“In two months, our effects have shown that the drug is effective in inhibiting viral replication in CELLS with SARS-CoV-2,” said Joanne Lemieux, professor of biochemistry at the University of Alberta School of Medicine and Dentistry in Canada.
Research published in Nature Communications examines two very similar drugs called GC373 and GC376, both paintings inhibiting proteases, a type of enzyme widely discovered in various types of living beings, adding viruses and humans, protecting paints by decomposing proteins into smaller building blocks. Protease inhibitors prevent or slow this process, restricting the replication of certain viruses. Several protease inhibitors are FDA approved for HIV remedy and researchers expect them to act the same way in SARS-CoV2 coronavirus.
Inflamed monkey cells and human lung cells with SARS-CoV2 virus in laboratory boxes tested protease inhibitors in them, and found that they were very effective at preventing virus replication.
“This drug is most likely for paints in humans, so we are encouraged to have it as an effective antiviral remedy for COVID-19 patients,” Lemieux said.
Coronavirus infection in cats in which the drug has been shown to be effective in treating is not the same as that of Covid-19 in humans. In cats, the infection is mild, but infrequently causes peritonitis, an abdominal infection that can be fatal. However, the researchers also observed precisely how the drugs join SARS-CoV2 protease and prevent the virus from replicaging, giving them confidence that the drug also has a smart chance of functioning in humans.
“As a general rule, for a drug to be tested clinically, it will have to be confirmed in the laboratory and then tested on animal models. Because this drug has already been used to treat cats with coronavirus, and is effective with little or no toxicity, it has already passed those steps and this allows us to move forward,” Lemieux said.
The drug worked in laboratory experiments at nanomolar concentrations, which meant that very little was needed to produce a significant effect on the virus. This is because if maximum concentrations of experimental drugs are needed in laboratory experiments, they are more likely to produce appearance effects in humans.
“Because of the falsified knowledge we and others have collected, we are conducting clinical trials for this drug as an antiviral drug for Covid-19,” Lemieux said.
Researchers are working with Anvive Life Sciences, which produces the veterinary medicine drug, to produce the amount for a human clinical trial. The company is currently conducting more animal studies with the drug to determine its protection and the study team expects it to be tested in humans until the end of this year.
Only another antiviral drug, remdesivir, has recently been approved for the Covid-19 remedy, after clinical trials have shown that it can boost recovery for some Patients with Covid-19; however, it is far from as expected. and if this protease inhibitor is promising in humans, it may simply provide some other remedy option, although its evaluation will likely take some time.
