title: An epimer of 5'-noraristeromycin and its antiviral properties.
abstract: A derivative of 5'-noraristeromycin epimeric at the 5'-nor center ((-)-3) has been prepared enantiospecifically in three steps from (+)-((1R,4S)-4-hydroxy-2-cyclopenten- 1-yl acetate. Compound (-)-3 was evaluated for antiviral activity against a large number of viruses and found to display marked activity against varicella-zoster virus, vaccinia virus, vesicular stomatitis virus, parainfluenza virus, reovirus, and cytomegalovirus. A similar antiviral activity spectrum was shown by the S-adenosylhomocysteine hydrolase inhibitors neplanocin A and carbocyclic 3-deazaadenosine. While equally potent as neplanocin A against most of the viruses tested, compound (-)-3 was significantly less cytotoxic. The results of this study suggest that (-)-3 should be pursued for the treatment of those virus infections [that is, pox (VV), rhabdo (VSV), paramyxo (parainfluenza), and reo] that appear to be exquisitively sensitive to the compound.
