COVID-19 agent molnupiravir
23 Nov 2023In response to the COVID-19 pandemic the anti-viral drug, molnupiravir, sold under the brand name Lagevrio®, was developed to treat mild to medium COVID-19 infection. Molnupiravir is a prodrug of the active substrate N4-hydroxycytidine (NHC), a synthetic ribonucleoside analogue. During the viral RNA replication the treatment introduces copying errors which inhibits the viral reproduction. In this application note from YMC Europe, explore how molnupiravir and its active agent β-d-N4-hydroxycytidine can be separated by using a YMC-Triart C18 column and a MS compatible mobile phase at pH 4.3 and relatively mild temperatures of 40°C.
