Description

Biochem/physiol Actions

Letermovir (AIC246) is an orally active, potent and selective human cytomegalovirus (HCMV) DNA terminase complex inhibitor that 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 µM, all other EC50 >10 µM).
