Abstract
Various carbocyclic analogues of adenosine, including aristeromycin (carbocyclic adenosine), carbocyclic 3-deazaadenosine, neplanocin A, 3-deazaneplanocin A, the 5′-nor derivatives of aristeromycin, carbocylic 3-deazaadenosine, neplanocin A and 3-deazaneplanocin A, and the 2-halo (i.e., 2-fluoro) and 6′-R-alkyl (i.e., 6′-R-methyl) derivatives of neplanocin A have been recognized as potent inhibitors of S-adenosylhomocysteine (AdoHcy) hydrolase. This enzyme plays a key role in methylation reactions depending on S-adenosylmethionine (AdoMet) as methyl donor. AdoHcy hydrolase inhibitors have been shown to exert broad-spectrum antiviral activity against pox-, paramyxo-, rhabdo-, filo-, bunya-, arena-, and reoviruses. They also interfere with the replication of human immunodeficiency virus through inhibition of the Tat transactivation process.Keywords
