title: The enantiomers of carbocyclic 5'-norguanosine: activity towards Epstein-Barr virus.
abstract: (-)-5'-noraristeromycin (1) has shown antiviral activity towards, particularly cytomegalovirus, vaccinia virus and measles while its (+)-enantiomer (2) is effective towards hepatitis B virus. To determine if the antiviral characteristics of 1 and 2 extended to the guanine analogues (3 and 4), these enantiomers were prepared and evaluated against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), cytomegalovirus (CMV), varicella zoster virus (VZV), Epstein-Barr virus (EBV), human herpes virus type 6 (HHV-6), human herpes virus type 8 (HHV-8), vaccinia virus (VV), cowpox virus (CV), vesicular stomatitis virus (VSV), respiratory syncytial virus (RSV), hepatitis B virus (HBV), and human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2). The only activity found for 3 was for Epstein-Barr virus in VCA Elisa (EC50 0.78 microg/mL), immunofluorescence assay for VCA or gp 350/250 (1.8-4.0 microg/mL) and DNA hybridization (EC50 0.82 microg/mL) assays with no accompanying toxicity seen in the host Daudi cells. No activity was noted for 4.
