This research investigates how antiviral drug resistance develops by examining structural changes in viral proteins. Using protein crystallography, it identified why SARS-CoV-2 mutations prevent Paxlovid binding and discovered two compounds capable of inhibiting resistant viruses. The findings could guide development of more effective antivirals against future drug-resistant viral infections.

Respiratory Syncytial Virus (RSV) hospitalises thousands of children each year, yet effective treatments remain unavailable. This research investigates a critical protein–protein interaction that enables RSV infection. By identifying and disrupting key molecular binding sites using AI, the work aims to support the development of targeted antiviral therapies for severe RSV.
