The P-L-dioxolane nucleosides show potent anti-VZV and anti-EBV activities, which can be related to the size of the halogen atoms [chlorovinyl (123) < bromovinyl (124) < iodovinyl (125) against VZV and iodovinyl < bromovinyl < chlorovinyl against EBV]. p-L-(£)-5-(2-Iodovinyl)uracil dioxolane (125, L IV-OddU) is 60-fold more potent against VZV than ACV. No inhibition of CEM cell growth or mt-DNA synthesis is observed for any compounds at concentrations up to 200 jiiM. ^^^ Unlike other D-configuration BVU analogs, such as BVdU and BVaraU, L-BV-OddU is metabolized only to its corresponding monophosphate instead of the dior triphosphate, which suggests a unique inhibitory mechanism other than DNA chain termination.
