title: Synthesis and enzymatic transformations of 5-halo-6-methoxy-5,6-dihydro derivatives of 5-[1-methoxy-2-halo (or 2,2-dihalo)ethyl]-2'-deoxyuridines as potential herpes simplex virus inhibitors.
abstract: The 5-halo-6-methoxy-5,6-dihydro derivatives of 5-[1-methoxy-2-halo(or 2,2-dihalo)ethyl]-2'-deoxyuridines (3-12) were synthesized and investigated as potential anti-herpes agents. These 5,6-dihydro derivatives were designed to act as potential prodrugs to 5-[1-methoxy-2-halo(or 2,2-dihalo)ethyl]-2'-deoxyuridines (2a-e), with enhanced metabolic stability, and ready conversion to the parent molecules. These 5,6-disubstituted-5,6-dihydro analogs are stable to E. coli thymidine phosphorylase, and undergo regeneration of the 5,6-olefinic bond to provide parent moieties (2a-e), upon incubation with glutathione at 37 degrees C. The compounds (3-12) themselves were found to be non-inhibitory against herpes simplex virus type-1 (HSV-1), likely due in part to their inability to undergo conversion to parent compounds in cell culture medium.
