 | Hazard Information | Back Directory |  | [Uses] 
 Letermovir acts as an orally or i.v administered cytomegalovirus terminus complex inhibitor, antiviral agent, used in the treatment of CMV infection which is prevalent in those with immunocompromised systems.
 |  | [Biological Activity] 
 Letermovir (AIC246) is an orally activepotent and selective human cytomegalovirus (HCMV) DNA terminase complex inhibitor th at blocks HCMV replication (EC50 = 0.9-3.1 nM among 17 clinial HCMV isolates; EC50 = 1.6-3.9 nM against 6 AD169-derived drug-resistant variants) by interfering with viral DNA cleavage/packaging. Letermovir exhibits little potency toward MCMV (Smith)RCMV (Maastricht)VZV (Oka)HSV-1 (166v VP22-GFP)HSV-2 (01-6332)HHV-6 (typeA-GS) or EBV (B95-8) (MCMV EC50 = 4.5 μMall other EC50 >10 μM).
