Researchers Innovate to Expand Oral Antiviral Options for COVID-19

A team of researchers from the University of Alberta is dedicated to improving the accessibility of oral antiviral medications for COVID-19. Currently, the only orally administered antiviral approved for COVID-19 is Pfizer’s Paxlovid, which utilizes a metabolic booster to prolong the drug’s effectiveness in the body. However, this approach limits its use for individuals who require other medications, specifically immunocompromised patients or those with chronic conditions. To address this limitation, the researchers embarked on a mission to develop second-generation antivirals that can be safely consumed alongside other medications.

By utilizing the Canadian Light Source (CLS) at the University of Saskatchewan, the research team, led by Professor Joanne Lemieux, analyzed the molecular structure of Paxlovid in detail. This examination enabled them to identify areas of the drug that could be modified. With this information, the team focused on modifying a specific area of the active drug molecule, eliminating the need for a separate booster drug. This advancement could potentially broaden the spectrum of individuals who can safely and effectively treat their COVID-19 infections.

The innovation of this research lies in its ability to enhance the potency of the antiviral drug while addressing its limitations. By modifying the drug molecule, the researchers have expanded the potential applications of the medication beyond its existing restrictions. This breakthrough could greatly benefit populations that were previously unable to access this treatment option due to their medication regimens.

Building on their success, Professor Lemieux and her colleagues are continuing their work in designing novel antiviral drugs to combat a range of viruses, including respiratory viruses beyond COVID-19. The utilization of the CLS synchrotron facility has been and continues to be crucial in their research, enabling the team to make significant strides in the field of antiviral drug discovery.

As the world grapples with ongoing viral threats, innovation in the field of antiviral drugs plays a pivotal role in safeguarding public health. The dedication of researchers like Professor Lemieux and her team at the University of Alberta is paving the way for more accessible and effective treatments against not only COVID-19 but also future emerging viruses. Their efforts highlight the importance of collaboration, advanced technology, and a commitment to providing solutions that benefit diverse populations.
