MaribavirMaribavir(GW257406X; BW1263W94; 1263W94) inhibits HCMV replication is by inhibition of an HCMV encoded protein kinase enzyme called UL97 or pUL97.
IC50 value:
Target: HCMV
in vitro: 1263W94 inhibited viral replication in a dose-dependent manner, with a mean 50% inhibitory concentration (IC50) of 0.12 ± 0.01 μM compared to a mean IC50 for GCV of 0.53 ± 0.04 μM, as measured by a multicycle DNA hybridization assay [1].
