A team of interdisciplinary researchers from the Institut National de la Recherche Scientifique (INRS) is hoping to identify effective COVID-19 therapeutics. With help from the Canadian Light Source (CLS) at the University of Saskatchewan, the team has been able to visualize the interaction between inhibitory molecules and viral proteins. This allows researchers to see if their drug designs work as intended.

"We have libraries of molecular fragments and drug candidates that we are testing," said Michael Maddalena, a research intern in Steven LaPlante's lab at INRS. "We are screening to see if they are active and actually stick to the virus's proteins or to essential human receptors where we think there are opportunities for drugs."

This research targets the proteins of the SARS-CoV-2 virus that are involved in its replication and survival. Their work also targets the essential human receptors that the virus depends on to enter human cells. Drugs that stick to human receptors are unlikely to be susceptible to viral mutants—ensuring that new therapeutics will be effective against new variants.

Getting a drug to stick to the proteins on SARS-CoV-2 or essential human receptors can prevent the virus from replicating, and stop the infection in its tracks. A therapeutic for COVID-19 like this should lessen the length and severity of the illness, keeping more people out of the hospital and improving patient outcomes.

The CMCF beamline at the CLS has been "enormously beneficial" to the team, according to Maddalena. The synchrotron allowed the researchers to collect high-quality data on their drug candidates quickly and efficiently. Their related research is published in ChemMedChem.

"Without access to the CLS, we definitely wouldn't be able to get the same quality of data that plays a big part in how we conduct our science," Maddalena said.
