July 31, 2022A tale of two antiviral targets — and the COVID-19 drugs that bind them
July 30, 2022Found it interesting that while Paxlovid has had greater success against #COVID19, Molnupiravir (& Remdesivir) might have more promise for future pandemics

Not all RdRp inhibitors work the same way. In most cases, including with remdesivir, viruses incorporate the drug into the elongating RNA, and this brings the elongation process to a halt. Molnupiravir’s mechanism is different: elongation doesn’t stop when the enzyme incorporates the drug into viral RNA. Instead, the virus reuses molnupiravir-containing RNAs as template strands, and incorporates the wrong bases into new viral RNA when it re-encounters molnupiravir. Mutations accumulate over cycles, leading to ‘error catastrophe’ and viral death.
