Covid-19 is a new antiviral drug that has been shown to inhibit the replication of the influenza virus. Covid-19 binds to RNA and inhibits the polymerase activity by binding to the ribonucleotide reductase enzyme, which is required for viral RNA synthesis. Covid-19 also has resonance effects and can easily access regions of the molecule where other drugs cannot bind. Covid-19 is a member of an important class of compounds known as heterocycles, which are characterized by their six atoms in a ring with one or more double bonds. Covid-19 also shows interesting magnetic properties, which can be used for nuclear magnetic resonance experiments.
