The naturally occurring adenine based carbocyclic nucleosides aristeromycin and neplanocin A and their 3-deaza analogues have found a prominent place in the search for diverse antiviral activity agent scaffolds because of their ability to inhibit S-adenosylhomocysteine (AdoHcy) hydrolase. Following the lead of these compounds, their 3-deaza-3-fluoroaristeromycin analogues have been synthesized and their effect on S-adenosylhomocysteine hydrolase and RNA and DNA viruses determined.
