The average 50% inhibitory concentration (IC50) values
for AD169 were 0.22 ± 0.09 µM 1263W94 and 5.36 ± 0.12 µM ganciclovir. For 35 human cytomegalovirus (HCMV) clinical isolates
the average IC50 was 0.42 ± 0.09 µM 1263W94, and
for 26 ganciclovir-susceptible HCMV clinical isolates the average
IC50 was 3.78 ± 1.62 µM ganciclovir. Nine HCMV
clinical isolates that were resistant to ganciclovir were completely
susceptible to 1263W94.
