Biological Activity

Description Molnupiravir (EIDD-2801, MK-4482) is an orally bioavailable prodrug of the ribonucleoside analog β-d-N4-hydroxycytidine (NHC; EIDD-1931) with broad-spectrum antiviral activity against SARS-CoV-2, MERS-CoV, SARS-CoV, and the causative agent of COVID-19.
Targets
SARS-CoV-2 [1] MERS-CoV [1] SARS-CoV [1]
In vitro

EIDD-2801 is an orally bioavailable NHC-prodrug. NHC is potently antiviral against SARS-CoV-2, MERS-CoV and SARS-CoV in primary human epithelial cell cultures without cytotoxicity. NHC is effective against remdesivir (RDV)-resistant vi-rus and multiple distinct zoonotic CoV. NHC antiviral activity is associated with increased viral mutation rates.[1]
In vivo

EIDD-2801 is efficiently hydrolyzed in vivo after absorption, resulting in detection of only free NHC in plasma.[2]

Therapeutic EIDD-2801 is potently antiviral against SARS-CoV in vivo but the degree of clinical benefit is dependent on the time of initiation post-infection. EIDD-2801 robustly reduces MERS-CoV infectious titers, viral RNA, and pathogenesis under both prophylactic and early therapeutic conditions.[1]
