In the scientific journal Pharmaceutics, researchers from the ESI International Chair of the CEU Cardenal Herrera University (CEU UCH) and ESI Group have just published a new computational topology strategy to identify existing medicines that could be applied to treat COVID-19 without waiting for the research and clinical trial phases required to develop a new medicine. This mathematical model applies topologic data analysis in a pioneering way in order to compare the three-dimensional structure of the target proteins of known medicines to SARS-CoV-2 coronavirus proteins such as protein NSP12, an enzyme in charge of replicating the viral RNA.
