The 9-(3,4-dihydroxybut-1-yl)guanine (bucyclovir, 23) with a hydroxyl directly attached to the butyl side chain is very potent against HSV-1 and HSV-2 (IC50=0.4 ?M against HSV-1 and 0.9 ?M against HSV-2). The stereochemistry of the 3-position of bucyclovir is crucial in determining the antiherpetic activities. While the R configuration is very potent, the S-isomer (24) is essentially inactive against HSV-1 and HSV-2
IC50
INHIBITOR->TARGET ORGANISM
The in vitro activities of penciclovir against HSV-1, HSV-2 and VZV are similar to those of aciclovir, with median IC50 values of 0.4, 1.5 and 4.0?µg/mL, respectively, in MRC-5 cells.
