Abstract:
The arbocyclic nucleosides aristeromycin and neplanocin have been studied as a source for new antiviral agents. A convenient synthesis of C-5'-truncated 3-deaza-1',6'-isoneplanocin, which combines the features of antiviral candidates 5'-noraristeromycin and 3-deaza-1',6'-isoneplanocin is reported from (-)-cyclopentenone to give the two C-4' epimers of 5'-nor-3-deaza isoneplanocin. Antiviral assays showed activity against the JC virus (EC50 = 1.12 µM for (4'R)-8; EC50 = 59.14 µM for (4'S)-7) and inactivity of both compounds against several DNA and RNA viruses. Both compounds lacked cytotoxicity.
